[0028] FIG. 1A illustrates an example of an electronic device including an LCoS panel.

[0029] FIG. 1A illustrates an example of an electronic device (101) including an LCoS panel (115). The electronic device (101) of FIG. 1A may be an example of the electronic device (1001) of FIG. 10. For example, the electronic device (101) may include at least a portion of, or correspond to at least a portion of, the electronic device (1001).

[0030] For example, the electronic device (101) may be implemented in various form factors. For example, the electronic device (101) may include a wearable device (or, a head mounted display (HMD)) worn on the user's head. For example, the wearable device may include an augmented reality (AR) device or a virtual reality (VR) device. However, the present disclosure is not limited thereto. For example, the electronic device may include not only an electronic device including the display of the bar type, but also an electronic device including the display that is a flexible display. For example, the flexible display may include a rollable display, a foldable display, or a multi-foldable display.

[0031] Referring to FIG. 1A, the electronic device (101) may include a processor (111), a display driver integrated circuitry (IC) (113), an LCoS panel (115), a light emitting driver IC (117), a light source (120), a polarization structure (125), and a projection structure (127).

[0032] For example, the processor (111) may be used to acquire an image. For example, the processor (111) may provide the image to the display driver IC (113). For example, the processor (111) may provide at least one command related to displaying the image to the display driver IC (113). For example, the processor (111) may include at least a part of the processor (1020) of FIG. 10.

[0033] For example, the processor (111) may include a central processing unit (CPU), a graphics processing unit (GPU), or a display controller (or display processing unit (DPU)) configured to process an image acquired from a volatile memory into a format suitable for the LCoS panel (115). For example, the processor (111) may be operatively or operably coupled with a display driver IC (113). For example, operatively or operably coupled with the processor (111) may indicate that the processor (111) is directly connected to the display driver IC (113). For example, operatively or operably coupled with the display driver IC (113) may indicate that the processor (111) is connected to the display driver IC (113) through another component of the electronic device (101). For example, the processor (111) may be connected to the display driver IC (113) via an interface. For example, the interface may be used to transmit an image from the processor (111) to the display driver IC (113). For example, the interface (225) may be a display serial interface (DSI) of the mobile industry process interface (MIPI) alliance. However, the embodiments of the present disclosure are not limited thereto. For example, the fact that the processor (111) is operatively coupled with the display driver IC (113) may indicate that the display driver IC (113) operates based on instructions executed by the processor (111). For example, the fact that the processor (111) is operatively coupled with the display driver IC (113) may indicate that the display driver IC (113) is controlled by the processor (111).

[0034] For example, the display driver IC (113) may process the image based on characteristics of the image and / or characteristics of the LCoS panel (115). For example, the display driver IC (113) may provide signals for displaying the image to the LCoS panel (115). For example, the display driver IC (113) may include at least a portion of a DDI (e.g., the DDI (1130) of FIG. 11). For example, the display driver IC (113) may be operatively coupled with the LCoS panel (115). For example, the display driver IC (113) being operatively coupled with the LCoS panel (115) may indicate that the display driver IC (113) is connected to the LCoS panel (115). For example, the fact that the display driver IC (113) is operatively coupled with the LCoS panel (115) may indicate that the LCoS panel (115) is controlled by the display driver IC (113). However, this is not limited thereto.

[0035] For example, the display driver IC (113) may include a first set of circuits for processing the image obtained from the processor (111). For example, the first set may be connected to the processor (111) among the processor (111) and the LCoS panel (115). For example, the display driver IC (113) may include a second set of circuits for obtaining the processed image from the first set and providing signals for displaying the obtained image to the LCoS panel (115). For example, the signals for displaying the obtained image may be provided for each of the pixels included in the pixel array (116) of the LCoS panel (115). For example, the signals may include pixel data (or data voltage) applied to each of the pixels, and a scan signal provided to each of the pixels.

[0036] For example, the first set may include an interface controller connected to the processor (111) via the interface. For example, the interface controller may be used to provide the image acquired from the processor (111) to an image processing circuit or a graphic random access memory (GRAM) and to provide a command acquired from the processor (111) to a command controller. For example, the interface controller may be included in the interface module (1131) of FIG. 11.

[0037] For example, the first set may include the image processing circuit. For example, the image processing circuit may process the image from the processor (111) to adjust the resolution, brightness, and / or size of the image. For example, the processed image may be provided to the second set. For example, the image processing circuit may be included in the image processing module (1135) of FIG. 11.

[0038] For example, the first set may further include the GRAM and the GRAM controller. For example, the GRAM may be used to store or record the image acquired from the processor (111). For example, the GRAM controller may be used to control the GRAM. The GRAM and the GRAM controller may be included in the memory (1133) of FIG. 11.

[0039] In the above example, the display driver IC (113) is described as including the first set of circuits for processing the image, but the present disclosure is not limited thereto. For example, the display driver IC (113) may not include the first set of circuits. For example, the processor (111) may perform processing on the image and then transmit it to the display driver IC (113). Accordingly, the display driver IC (113) may provide the processed image to the LCoS panel (115) and may not perform additional processing. At this time, the display driver IC (113) may control the LCoS panel (115) and the light emitting driver IC (117) to display the processed image.

[0040] For example, the second set may include a timing controller. For example, the timing controller may be used to provide a synchronization signal (or timing signal) to the GRAM controller, the source driver circuit, the gate driver circuit, and / or the light emitting driver circuit. For example, the synchronization signal may include a vertical synchronization signal (Vsync) (or frame) and a horizontal synchronization signal (Hsync). For example, the synchronization signal may be generated by the timing controller or may be generated by a synchronization signal generation circuit located outside the display driver IC (113). For example, the timing controller may be used to provide signals for controlling the source driver circuit, the gate driver circuit, and / or the light emitting driver. For example, at least some of the second set may be included in the mapping module (1137) of FIG. 11.

[0041] For example, the second set may include the source driver circuit. For example, the source driver circuit may be used to provide the pixel data to be applied to the pixel electrode of each pixel. For example, the source driver circuit may be used to provide the pixel data corresponding to a specific grayscale within the grayscale that the pixels of the LCoS panel (115) can implement. For example, depending on the size of the pixel data, the grayscale implemented by each pixel may change.

[0042] For example, the second set may include the gate driver circuit. For example, the gate driver circuit may be used to provide a gate voltage applied to a gate electrode of each pixel to the LCoS panel (115). The gate voltage may include a voltage for driving (e.g., turning on / off) a transistor included in the pixel. For example, the gate voltage may be referenced as a scan signal.

[0043] For example, the second set may include a light emitting driver circuit. For example, the light emitting driver circuit may be used to provide a light emitting signal to the light emitting driver IC (117). For example, the light emitting signal may be provided to the light emitting driver IC (117) to control the light emitting driver IC (117) (or the light emitting circuit within the light emitting driver IC (117)) to emit light with respect to pixels to be used for displaying an image according to the pixel data and the scan signal. For example, the light emitting signal may indicate a voltage, timing, and light emitting area for emitting the light in accordance with synchronization for displaying the image. For example, the light emitting area may include an area of ​​the pixel array (116) to which light emitted by the light emitting circuits (121, 122, 123) within the light source (120) is provided. For example, the above-described light emission signal can be used to synchronize between the display driver IC (113) and the light emission driver IC (117).

[0044] For example, the LCoS panel (115) may include a pixel array (116). For example, the pixel array (116) may include a plurality of pixels. For example, the pixels may be configured as a plurality of lines. Specific details related thereto are exemplified and described below with reference to FIG. 2A.

[0045] For example, the pixels of the LCoS panel (115) can receive (or obtain) light transmitted (or provided) from a light source (120) through a polarizing structure (125). For example, the pixels can reflect the light transmitted from the light source (120). The light reflected by the pixels passes through the polarizing structure (125) again, and the passed light can be provided (or displayed) to the outside of the electronic device (101) through a projection structure (127). For example, the LCoS panel (115) can be an example of an LCD panel (or LCD). An LCoS panel (115) that displays an image using reflected light can be referred to as a reflective LCoS.

[0046] For example, the light emitting driver IC (117) can control the light source (120) to emit light for displaying the image. For example, the light emitting driver IC (117) can be electrically connected to the light emitting circuits (121, 122, 123) included in the light source (120). For example, the light emitting driver IC (117) can adjust the timing, area, and intensity of light emitted through the light emitting circuits (121, 122, 123). In Fig. 1A, the light emitting driver IC (117) is illustrated as being controlled by the display driver IC (113), but the present disclosure is not limited thereto. For example, the light emitting driver IC (117) can also be controlled by the processor (111) instead of the display driver IC (113).

[0047] For example, the light source (120) can provide light to the LCoS panel (115) as controlled by the light emitting driver IC (117). For example, the light source (120) can include a first light emitting circuit (121) configured to emit light (121a) of a first color. For example, the first color can include R (red) color. For example, the light source (120) can include a second light emitting circuit (122) configured to emit light (122a) of a second color. For example, the second color can include G (green) color. For example, the light source (120) can include a third light emitting circuit (123) configured to emit light (123a) of a third color. For example, the third color can include B (blue) color. In the example of FIG. 1A, the light source (120) is illustrated as including three light-emitting circuits, but the present disclosure is not limited thereto. For example, the light source (120) may further include an additional light-emitting circuit for a fourth color. For example, the fourth color may include a W (white) color.

[0048] For example, the polarizing structure (125) may be used to provide light from a light source (120) to the LCoS panel (115) (or pixel array (116)) and to provide light reflected from the LCoS panel (115) to the projection structure (127). For example, the polarizing structure (125) may be referred to as a PBS (polarizing beam splitter).

[0049] For example, the projection structure (127) may be used to provide (or display) light passing through the polarizing structure (125) to the outside of the electronic device (101). For example, the projection structure (127) may be referred to as a projection.

[0050] In FIG. 1A, a case in which the display driver IC (113) and the light emitting driver IC (117) are implemented as separate components is illustrated, but the present disclosure is not limited thereto. For example, the display driver IC (113) and the light emitting driver IC (117) may be implemented as a single control circuit. For example, the single control circuit may be included in the LCoS panel (115).

[0051] The components included in the electronic device (101) of FIG. 1A are merely exemplary, and the present disclosure is not limited thereto. For example, the electronic device (101) may not include at least some of the components, and may further include other components in addition to the components. For example, the electronic device (101) may include a memory that includes one or more storage media and stores instructions. The memory may include at least a portion of the memory (1030) of FIG. 10 or may correspond to at least a portion of the memory (1030) of FIG. 10. The instructions, when individually or collectively executed by the processor (111), may cause the electronic device (101) to generate or acquire an image to be displayed through the display. For example, the display may include a display driver IC (113), an LCoS panel (115), and a light emitting driver IC (117). The above instructions, when executed individually or collectively by the processor (111), may provide data for the image to the display (or the display driver IC (display driving integrated circuit, DDI) (1130, display driving circuit (1130) of FIG. 11) to display the image through the display.

[0052] Figures 1b and 1c illustrate examples of a method for displaying an image using an LCoS panel.

[0053] FIG. 1b and FIG. 1c illustrate an example of a method for displaying an image (135) using the LCoS panel (115) of FIG. 1a. For example, the image (135) may be provided from a processor (111) to a display driver IC (113).

[0054] For example, in the example of the electronic device (101) of FIG. 1A, if the light source (120) includes light-emitting circuits (121, 122, 123) that emit light of multiple colors, the image (135) can be displayed by displaying partial images (131, 132, 133). For example, the first partial image (131) can be an image expressed based on a first color of the image (135). For example, the second partial image (132) can be an image expressed based on a second color of the image (135). For example, the third partial image (133) can be an image expressed based on a third color of the image (135).

[0055] For example, the display driver IC (113) can identify pixel data for displaying the image (135). For example, the display driver IC (113) can identify first pixel data of a first color for the image (135) (or, the first partial image (131)). For example, the display driver IC (113) can identify second pixel data of a second color for the image (135) (or, the second partial image (132)). For example, the display driver IC (113) can identify third pixel data of a third color for the image (135) (or, the third partial image (131)).

[0056] Referring to example (130) of FIG. 1B, the display driver IC (113) may apply pixel data to pixels of the LCoS panel (115) and emit light with respect to the pixels to which the pixel data has been applied, in order to display an image (135). Hereinafter, in the present disclosure, scanning may include applying pixel data to the pixel electrode of each of the pixels by providing a scan signal to the gate electrode of the transistor of each of the pixels of the LCoS panel (115). In addition, in the present disclosure, emission may include controlling a light emitting circuit to emit light of a specific color with respect to at least some of the pixels of the LCoS panel (115) using the light emitting driver IC (117). The at least some may include pixels to which pixel data has been applied.

[0057] Example (130) illustrates a timing diagram in which an R scan (140), an R emission (145), a G scan (150), a G emission (155), a B scan (160), and a B emission (165) are performed. For example, the R scan (140) may represent the scan for applying pixel data for a first color to a pixel electrode. For example, the R emission (145) may include the emission for emitting light of the first color with respect to a pixel including a pixel electrode to which pixel data for the first color has been applied. For example, the G scan (150) may represent the scan for applying pixel data for a second color to a pixel electrode. For example, the G emission (155) may include the emission for emitting light of the second color with respect to a pixel including a pixel electrode to which pixel data for the second color has been applied. For example, B scan (160) may represent the scan for applying pixel data for a third color to a pixel electrode. For example, B emission (165) may include the emission for emitting light of the third color with respect to a pixel including a pixel electrode to which pixel data for the third color has been applied.

[0058] Referring to the R scan (140) of example (130), the display driver IC (113) can apply the first pixel data for the first color to the pixels of the LCoS panel (115) within a first time interval (141). For example, the first time interval (141) can represent the time between a start time (141a) and an end time (141b). Referring to the R emission (145) of example (130), the display driver IC (113) can control the first emission circuit (121) using the emission driver IC (117) to emit light of the first color for the pixels to which the first pixel data is applied within a second time interval (146). For example, the second time interval (146) can represent the time between a start time (146a) and an end time (146b). For example, the start time (146a) of the second time interval (146) may be a time after the reference time (144) from the end time (141b) of the first time interval (141). For example, the reference time (144) may be related to the response speed of the liquid crystal of the LCoS panel (115). For example, the reference time (144) may be referred to as a waiting time for changing the state of the liquid crystal according to the voltage (or data voltage, pixel data) applied according to the scan. For example, the display driver IC (113) may display the first partial image (131) by performing an R scan (140) within the first time interval (141) and an R emission (145) within the second time interval (146).

[0059] Referring to the G scan (150) of the example (130), the display driver IC (113) can apply the second pixel data for the second color to the pixels of the LCoS panel (115) within a third time interval (151). For example, the third time interval (151) can represent a time between a start time (151a) and an end time (151b). For example, the start time (151a) of the third time interval (151) can be a time after the end time (146b) of the second time interval (146). Referring to the G emission (155) of the example (130), the display driver IC (113) can control the second emission circuit (122) using the emission driver IC (117) to emit light of the second color with respect to the pixels to which the second pixel data is applied within a fourth time interval (156). For example, the fourth time interval (156) may represent the time between the start time (156a) and the end time (156b). For example, the start time (156a) of the fourth time interval (156) may be the time after the reference time (154) from the end time (151b) of the third time interval (151). For example, the reference time (154) may correspond to the reference time (144). For example, the display driver IC (113) may display the second partial image (132) by performing a G scan (150) within the third time interval (151) and a G emission (155) within the fourth time interval (156).

[0060] Referring to the B scan (160) of the example (130), the display driver IC (113) can apply the third pixel data for the third color to the pixels of the LCoS panel (115) within a fifth time interval (161). For example, the fifth time interval (161) can represent a time between a start time (161a) and an end time (161b). For example, the start time (161a) of the fifth time interval (161) can be a time after the end time (156b) of the fourth time interval (156). Referring to the B emission (165) of the example (130), the display driver IC (113) can control the third emission circuit (123) using the emission driver IC (117) to emit light of the third color for the pixels to which the third pixel data is applied within a sixth time interval (166). For example, the sixth time interval (166) may represent the time between the start time (166a) and the end time (166b). For example, the start time (166a) of the sixth time interval (166) may be the time after the reference time (164) from the end time (161b) of the fifth time interval (161). For example, the reference time (164) may correspond to the reference time (144). For example, the display driver IC (113) may display the third partial image (133) by performing the B scan (160) within the fifth time interval (161) and the B emission (165) within the sixth time interval (166).

[0061] In Fig. 1b, the time for displaying the image (135) may be referred to as a frame. For example, the frame may be referred to as the time from the start time (141a) of the first time interval (141) to the end time (146b) of the sixth time interval (166). In Fig. 1b, one R scan (140), one R flash (145), one G scan (150), one G flash (155), one B scan (160), and one B flash (165) may be performed to display the image (135). In the above example, if the display of the image (135) is repeated 60 times per second, the driving frequency (or refresh rate) of the display may be 60 Hz (Hertz). However, the present disclosure is not limited thereto. For example, to display an image (135), one R scan (140), one R flash (145), one G scan (150), one G flash (155), one B scan (160), and one B flash (165) may be performed, and then additionally one R scan (140), one R flash (145), one G scan (150), one G flash (155), one B scan (160), and one B flash (165) may be repeatedly performed. In the above example, since the display of the image (135) is repeated 120 times per second, the driving frequency (or, refresh rate) of the display may be 120 Hz.

[0062] Example (170) of FIG. 1c illustrates an example of scanning and luminescence performed on an LCoS panel (115) according to example (130) of FIG. 1b.

[0063] Referring to example (171), the display driver IC (113) may perform an R scan (140) on the LCoS panel (115) within a first time interval (141). At this time, the R scan (140) may be sequentially performed on the pixels of the LCoS panel (115) within the first time interval (141). For example, if the pixels are composed of pixel lines extending from pixel line #1 to pixel line #n, the display driver IC (113) may perform an R scan (140) on the pixels of pixel line #1 in a first time section of the first time interval (141), and sequentially perform an R scan (140) on the pixels of pixel line #2 in a second time section of the first time interval (141) after the first time section. Thereafter, the R scan (140) may be sequentially performed on the pixels of pixel line #n.

[0064] Referring to example (172), the display driver IC (113) can perform R light emission (145) within the second time interval (146). For example, the R light emission (145) can start from a time after the reference time (144) from the first time interval (141) (or, the end time (141b) of the first time interval (141)). For example, the display driver IC (113) can control the first light emission circuit (121) using the light emission driver IC (117) so that all pixels of the LCoS panel (115) (i.e., pixels of pixel line #1 to pixel line #n) emit light of the first color during the second time interval (146). This may be because the light emission elements of the first light emission circuit (121) are configured as one unit and thus emit light simultaneously.

[0065] Referring to example (173), the display driver IC (113) may perform a G scan (150) on the LCoS panel (115) within a third time interval (151). At this time, the G scan (150) may be sequentially performed on the pixels of the LCoS panel (115) within the third time interval (151). For example, if the pixels are composed of pixel lines extending from pixel line #1 to pixel line #n, the display driver IC (113) may perform a G scan (150) on the pixels of pixel line #1 in a first time interval of the third time interval (151), and sequentially perform a G scan (150) on the pixels of pixel line #2 in a second time interval of the third time interval (151) following the first time interval. Thereafter, the G scan (150) may be sequentially performed on the pixels of pixel line #n.

[0066] Referring to example (174), the display driver IC (113) can perform G light emission (155) within the fourth time interval (156). For example, the G light emission (155) can start from a time after the reference time (154) (or the reference time (144)) from the third time interval (151) (or the end time (151b) of the third time interval (151)). For example, the display driver IC (113) can control the second light emission circuit (122) using the light emission driver IC (117) to emit light of a second color for all pixels of the LCoS panel (115) (i.e., pixels of pixel line #1 to pixel line #n) during the fourth time interval (156). This may be because the light emission elements of the second light emission circuit (122) are configured as one unit and thus emit light simultaneously.

[0067] Referring to example (175), the display driver IC (113) may perform a B scan (160) on the LCoS panel (115) within a fifth time interval (161). At this time, the B scan (160) may be sequentially performed on the pixels of the LCoS panel (115) within the fifth time interval (161). For example, if the pixels are composed of pixel lines extending from pixel line #1 to pixel line #n, the display driver IC (113) may perform a B scan (160) on the pixels of pixel line #1 in a first time interval of the fifth time interval (161), and sequentially perform a B scan (160) on the pixels of pixel line #2 in a second time interval of the fifth time interval (161) following the first time interval. Thereafter, the B scan (160) may be sequentially performed on the pixels of pixel line #n.

[0068] Referring to example (176), the display driver IC (113) can perform B light emission (165) within the sixth time interval (166). For example, the B light emission (165) can start from a time after the reference time (164) (or the reference time (144)) from the fifth time interval (161) (or the end time (161b) of the fifth time interval (161)). For example, the display driver IC (113) can control the third light emission circuit (123) using the light emission driver IC (117) to emit light of a third color for all pixels of the LCoS panel (115) (i.e., pixels of pixel line #1 to pixel line #n) during the sixth time interval (166). This may be because the light emission elements of the third light emission circuit (123) are configured as one unit and thus emit light simultaneously.

[0069] Referring to FIGS. 1B and 1C, when the electronic device (101) uses a light source (120) configured to emit light for all pixels of the LCoS panel (115) (or light-emitting circuits (121, 122, 123) of the light source (120)), the electronic device (101) waits for the scan to be completed before performing light emission. Accordingly, a limitation of the driving frequency of the LCoS panel (115) of the electronic device (101) may occur. In other words, the electronic device (101) may not be able to provide a driving frequency of the LCoS panel (115) above a certain level. In addition, the electronic device (101) emits light for all pixels even when there is no need to emit light for all pixels of the LCoS panel (115). Accordingly, the power consumed by the LCoS panel (115) and the light source (120) of the electronic device (101) may increase. In other words, power consumption may increase regardless of the image being displayed.

[0070] For example, if the electronic device (101) is the AR device, the display (e.g., LCoS panel (115)) of the electronic device (101) may be exposed to the outside of the electronic device (101). Accordingly, high brightness may be required for the electronic device (101) to display a visual object that at least partially overlaps the external environment on the display. In addition, the electronic device (101), which is the AR device, may display a visual object (e.g., an indicator) that is displayed on a part, not the entire display area, of the display. Accordingly, power consumption may be reduced by the electronic device (101) performing a display on a part (or some pixels) of the display area (or pixels).

[0071] The present disclosure can utilize local dimming driving to improve the limitations of the driving frequency and the increase in power consumption as described above. For example, local dimming driving can be performed by controlling the light-emitting driver IC (117) and the light source (120) to emit light with respect to some pixels of the pixels of the LCoS panel (115). For specific details related to the local dimming driving, reference may be made to FIGS. 2A and 2B below.

[0072] Figures 2a and 2b illustrate examples of local dimming driving of an LCoS panel.

[0073] Fig. 2a illustrates an example (200) of local dimming driving of an LCoS panel (115). In the example (200), the LCoS panel (115) may be an example of the LCoS panel (115) of Fig. 1a. For example, the pixel array (116) may be the pixel array (116) of Fig. 1a.

[0074] For example, in order to drive local dimming of the LCoS panel (115), the light source (120) may include a light emitting circuit implemented as a plurality of blocks, rather than a light emitting circuit implemented as a single unit. For example, the first light emitting circuit (201) of the light source (120) may be composed of a plurality of blocks (211, 212, 213, 214). For example, the first light emitting circuit (201) may be an example of the first light emitting circuit (121) of FIG. 1A. For example, the second light emitting circuit (202) of the light source (120) may be composed of a plurality of blocks (221, 222, 223, 224). For example, the second light emitting circuit (202) may be an example of the second light emitting circuit (122) of FIG. 1A. For example, the third light-emitting circuit (203) of the light source (120) may be composed of a plurality of blocks (231, 232, 233, 234). For example, the third light-emitting circuit (203) may be an example of the third light-emitting circuit (123) of FIG. 1A. For example, each of the blocks may include a plurality of light-emitting elements. For example, the blocks may each correspond to pixel lines of the LCoS panel (115). For example, the first block (211) (or the first block (221), the first block (231)) may correspond to the first pixel line of the LCoS panel (115) (e.g., pixel line #1 of FIG. 1C). For example, the nth block (214) (or, the nth block (224), the nth block (234)) may correspond to the nth pixel line (e.g., pixel line #n of FIG. 1C) of the LCoS panel (115). In the above example, the block and the pixel line are described as corresponding 1:1, but the present disclosure is not limited thereto. For example, the block and the pixel line may correspond n:1, 1:n. Hereinafter, for the convenience of explanation, a 1:1 correspondence is assumed.

[0075] For example, the light emitting circuits (201, 202, 203) may be connected to the light emitting driver IC (117). For example, the light emitting driver IC (117) may control the light emitting circuits (201, 202, 203) to emit (or drive) light in areas of the light emitting elements. For example, the light emitting driver IC (117) may control the first block (211) of the first light emitting circuit (201) (or some light emitting elements of the first block (211)) to emit light of a first color. In order to control the areas of the light emitting elements, the light emitting driver IC (117) may be electrically connected to the light emitting circuits (201, 202, 203) using control lines arranged along the rows and columns of each of the light emitting circuits (201, 202, 203).

[0076] For example, the direction of the scan performed on the pixels of the LCoS panel (115) may be the same as the direction of the light emission performed on the pixels (or the order in which light is transmitted in the blocks). For example, when the scan is performed in a direction from pixel line #1 (e.g., pixel line #1 of FIG. 1C) of the LCoS panel (115) to pixel line #n, the light emission may be performed in a direction from the first block (211) to the n-th block (214).

[0077] For example, the display driver IC (113) can perform local dimming driving of the LCoS panel (115) by controlling some of the light-emitting circuits (201, 202, 203) to be driven by using the light-emitting driver IC (117). For example, the display driver IC (113) can control some of the light-emitting circuits (201, 202, 203) to emit light by using the light-emitting driver IC (117). At this time, the display driver IC (113) can control the remaining light-emitting circuits to refrain from (or stop) emitting light by using the light-emitting driver IC (117). In addition, for example, the display driver IC (113) can control some blocks (or some light-emitting elements) of the some of the light-emitting circuits to emit light by using the light-emitting driver IC (117).

[0078] For example, the emission time of light emitted from each of the light emitting circuits (201, 202, 203) can be adjusted according to the required brightness, the characteristics of the light emitting elements within the light emitting circuit, or the properties (e.g., gradation, brightness) of the image to be displayed. In addition, for example, the brightness (or light quantity) of the lights emitted from blocks (or light emitting elements) within one light emitting circuit can be set differently from each other.

[0079] FIG. 2b illustrates an example (250) of a method for displaying an image (257) using a light-emitting circuit composed of one unit and an example (255) of a method for displaying an image (257) using a light-emitting circuit composed of a plurality of blocks.

[0080] Referring to example (250), the display driver IC (113) can control the light emitting circuits (261, 262, 263) to emit light using the light emitting driver IC (117) to display the image (257). Each of the light emitting circuits (261, 262, 263) can be an example of a light emitting circuit configured as a single unit. For example, the display driver IC (113) can control a first light emitting circuit (261) configured to emit light of a first color to emit light of the first color. For example, the display driver IC (113) can control a second light emitting circuit (262) configured to emit light of a second color to emit light of the second color after emitting light of the first color. For example, the display driver IC (113) can control the third light-emitting circuit (263), which is configured to emit light of a third color after emitting light of the second color, to emit light of the third color. At this time, the image (257) can be displayed based on the light of the second color emitted by the second light-emitting circuit (262) with respect to pixels within an area (257a) to which pixel data for the second color has been applied.

[0081] Alternatively, referring to example (255), the display driver IC (113) may control the second light-emitting circuit (202) to emit light using the light-emitting driver IC (117) to display the image (257). For example, the display driver IC (113) may control the first light-emitting circuit (201) configured to emit light of a first color to refrain from emitting light of the first color. For example, the display driver IC (113) may control the second light-emitting circuit (202) configured to emit light of a second color to emit light of the second color. More specifically, the display driver IC (113) may control a part (221a) of the first block (221) of the second block (222) and a part (222a) of the second block (222) of the second light-emitting circuit (202) to emit light of the second color. The light of the second color emitted by a portion (221a) of the first block (221) and a portion (222a) of the second block (222) can be emitted with respect to pixels within an area (257a) to which pixel data for the second color has been applied. For example, the display driver IC (113) can control a third light-emitting circuit (203) configured to emit light of a third color after emitting light of the second color to refrain from emitting light of the third color.

[0082] As described above, the electronic device (101) according to the present disclosure can reduce power consumption by emitting light to pixels that are actually used to display an image and light-emitting elements corresponding to the pixels through local dimming driving of the LCoS panel (115).

[0083] Figure 3a shows an example of pixels of an LCoS panel for local dimming driving.

[0084] FIG. 3A illustrates an example (300) of pixels included in a pixel array (116) of an LCoS panel (115). In the example (300), four pixels included in the pixel array (116) are illustrated, but this is merely an example for convenience of explanation, and the present disclosure is not limited thereto.

[0085] Referring to example (300), the pixel array (116) may include a first pixel (301), a second pixel (302), a third pixel (303), and a fourth pixel (304). For example, the first pixel (301) and the second pixel (302) may constitute a pixel line (300a). For example, the third pixel (303) and the fourth pixel (304) may constitute a pixel line (300b) following (or consecutive to) the pixel line (300a). In example (300), each of the pixel line (300a) and the pixel line (300b) is illustrated as including two pixels, but the present disclosure is not limited thereto. For example, each pixel line may include three or more pixels.

[0086] For example, the first pixel (301) may include a pixel electrode (310) and a first transistor (311). For example, the pixel electrode (310) may be formed of metal for reflecting light provided from a light source (120). For example, the pixel electrode (310) may be formed of a metal plate or a metal thin film. For example, the first transistor (311) may include a gate electrode (311a) electrically connected to a first scan line (312) (e.g., Scan1), a first electrode (311b) electrically connected to a first data line (313) (e.g., Data1), and a second electrode (311c) electrically connected to the pixel electrode (310). For example, the first electrode (311b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode (311c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0087] For example, similar to the first pixel (301), the second pixel (302) may include a pixel electrode (314) and a first transistor (315). The specific details of the pixel electrode (314) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (315) may be substantially the same as those of the first transistor (311). For example, the first transistor (315) may be electrically connected to a first scan line (312) (e.g., Scan1) and a first data line (317) (e.g., Data2).

[0088] Also, for example, similar to the first pixel (301), the third pixel (303) may include a pixel electrode (320) and a first transistor (321). The specific details of the pixel electrode (320) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (321) may be substantially the same as those of the first transistor (311). For example, the first transistor (321) may be electrically connected to a first scan line (322) (e.g., Scan2) and a first data line (313) (e.g., Data1).

[0089] Also, for example, similar to the first pixel (301), the fourth pixel (304) may include a pixel electrode (324) and a first transistor (325). The specific details of the pixel electrode (324) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (325) may be substantially the same as those of the first transistor (311). For example, the first transistor (325) may be electrically connected to a first scan line (322) (e.g., Scan2) and a first data line (317) (e.g., Data2).

[0090] For example, the display driver IC (113) can perform a scan for the first pixel (301). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (310) through the first data line (313) by providing a scan signal to the gate electrode (311a) of the first transistor (311) through the first scan line (312). For example, the display driver IC (113) can perform a scan for the second pixel (302). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (314) through the first data line (317) by providing a scan signal to the gate electrode of the first transistor (315) through the first scan line (312). For example, the display driver IC (113) can perform a scan for the third pixel (303). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (320) through the first data line (313) by providing a scan signal to the gate electrode of the first transistor (321) through the first scan line (322). For example, the display driver IC (113) can perform a scan for the fourth pixel (304). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (324) through the first data line (317) by providing a scan signal to the gate electrode of the first transistor (325) through the first scan line (322).

[0091] As described above, a single scan line may be used to provide scan signals to pixels within a single pixel line (e.g., a row). A single data line may be used to apply pixel data to pixels arranged in a direction perpendicular to the pixel line (e.g., a column).

[0092] Figures 3b and 3c illustrate a first example of local dimming driving.

[0093] FIG. 3B illustrates a first example (330) of local dimming driving performed using the light source (120) of FIG. 2A and the LCoS panel (115) of FIG. 3A. The local dimming driving of the first example (330) may include performing light emission of a specific color (e.g., R light emission) while a scan of a specific color (e.g., R scan) is performed.

[0094] A first example (330) illustrates a timing diagram in which an R scan (340), an R emission (345), a G scan (350), a G emission (355), a B scan (360), and a B emission (365) are performed. For example, the R scan (340) may represent the scan for applying pixel data for a first color to a pixel electrode. For example, the R emission (345) may include the emission for emitting light of the first color with respect to a pixel including a pixel electrode to which pixel data for the first color has been applied. For example, the G scan (350) may represent the scan for applying pixel data for a second color to a pixel electrode. For example, the G emission (355) may include the emission for emitting light of the second color with respect to a pixel including a pixel electrode to which pixel data for the second color has been applied. For example, B scan (360) may represent the scan for applying pixel data for a third color to a pixel electrode. For example, B emission (365) may include the emission for emitting light of the third color with respect to a pixel including a pixel electrode to which pixel data for the third color has been applied.

[0095] Referring to the R scan (340) of the first example (330), the display driver IC (113) may apply the first pixel data for the first color to the pixels of the LCoS panel (115) within a first time interval (341). For example, the first time interval (341) may represent the time between a start time (341a) and an end time (341b). For example, the display driver IC (113) may apply the first pixel data for the first color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 3A) of the LCoS panel (115) within a first time section (342) within the first time interval (341). For example, the first time section (342) may extend from the start time (341a) of the first time interval (341). Although not illustrated in the first example (330), in each of the time sections within the first time interval (341), the display driver IC (113) may sequentially apply the first pixel data for the first color to the pixels of each pixel line. For example, in a second time section of the first time interval (341) extending from the end time of the first time section (342) of the first time interval (341), the first pixel data for the first color may be applied to the pixels of the pixel line following the first pixel line (e.g., the pixel line (300b) of FIG. 3A).

[0096] Referring to the R emission (345) of the first example (330), the display driver IC (113) can control the first emission circuit (201) using the emission driver IC (117) to emit light of the first color for the pixels to which the first pixel data is applied within a second time interval (346). For example, the second time interval (346) can represent a time between a start time (346a) and an end time (346b). For example, the start time (346a) of the second time interval (346) can be a time before the end time (341b) of the first time interval (341). For example, the start time (346a) can be a time after the reference time (144) from the end time of the first time section (342). For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 3A) to which the first pixel data for the first color of the LCoS panel (115) is applied within the first time section (347) of the second time interval (346). For example, the start time of the first time section (347) may be the same as the start time (346a) of the second time interval (346). For example, the length of the first time section (347) may be longer than or equal to the length of the first time section (342). Although not shown in the first example (330), in each of the time sections within the second time interval (346), the display driver IC (113) can control the first light-emitting circuit (201) using the light-emitting driver IC (117) to sequentially emit light of the first color for each pixel of the pixel lines to which the first pixel data for the first color has been applied.For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the second pixel line to which the first pixel data for the first color of the LCoS panel (115) is applied within the second time section (348) of the second time interval (346). For example, the end time of the second time section (348) may be the same as the end time (346b) of the second time interval (346). The second pixel line may represent the last pixel line among the pixel lines of the LCoS panel (115).

[0097] Referring to the G scan (350) of the first example (330), the display driver IC (113) may apply the second pixel data for the second color to the pixels of the LCoS panel (115) within a third time interval (351). For example, the third time interval (351) may represent a time between a start time (351a) and an end time (351b). For example, the start time (351a) of the third time interval (351) may be a time after the end time (346b) of the second time interval (346). For example, the display driver IC (113) may apply the second pixel data for the second color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 3A) of the LCoS panel (115) within a first time section (352) within the third time interval (351). For example, the first time interval (352) may extend from the start time (351a) of the third time interval (351). Although not illustrated in the first example (330), in each of the time intervals within the third time interval (351), the display driver IC (113) may sequentially apply the second pixel data for the second color to the pixels of each of the pixel lines. For example, in the second time interval of the third time interval (351) extending from the end time of the first time interval (352) of the third time interval (351), the second pixel data for the second color may be applied to the pixels of the pixel line following the first pixel line (e.g., the pixel line (300b) of FIG. 3a).

[0098] Referring to the G emission (355) of the first example (330), the display driver IC (113) can control the second emission circuit (202) using the emission driver IC (117) to emit light of the second color for the pixels to which the second pixel data is applied within the fourth time interval (356). For example, the fourth time interval (356) can represent the time between a start time (356a) and an end time (356b). For example, the start time (356a) of the fourth time interval (356) can be a time before the end time (351b) of the third time interval (351). For example, the start time (356a) can be a time after the reference time (144) from the end time of the first time section (352). For example, the display driver IC (113) may control the second light-emitting circuit (202) using the light-emitting driver IC (117) to emit light of the second color for the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 3A) to which the second pixel data for the second color of the LCoS panel (115) is applied within the first time interval (357) within the fourth time interval (356). For example, the start time of the first time interval (357) may be the same as the start time (356a) of the fourth time interval (356). For example, the length of the first time interval (357) may be longer than or equal to the length of the first time interval (352). Although not shown in the first example (330), in each of the time sections within the fourth time interval (356), the display driver IC (113) can control the second light emitting circuit (202) using the light emitting driver IC (117) to sequentially emit light of the second color for each pixel of the pixel lines to which the second pixel data for the second color has been applied.For example, the display driver IC (113) can control the second light-emitting circuit (202) using the light-emitting driver IC (117) to emit light of the second color with respect to the pixels of the second pixel line to which the second pixel data for the second color of the LCoS panel (115) is applied within the second time interval (358) of the fourth time interval (356). For example, the end time of the second time interval (358) can be the same as the end time (356b) of the fourth time interval (356).

[0099] Referring to the B scan (360) of the first example (330), the display driver IC (113) may apply the third pixel data for the third color to the pixels of the LCoS panel (115) within a fifth time interval (361). For example, the fifth time interval (361) may represent a time between a start time (361a) and an end time (361b). For example, the start time (361a) of the fifth time interval (361) may be a time after the end time (356b) of the fourth time interval (356). For example, the display driver IC (113) may apply the third pixel data for the third color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 3A) of the LCoS panel (115) within a first time section (362) within the fifth time interval (361). For example, the first time interval (362) may extend from the start time (361a) of the fifth time interval (361). Although not illustrated in the first example (330), in each of the time intervals within the fifth time interval (361), the display driver IC (113) may sequentially apply the third pixel data for the third color to the pixels of each of the pixel lines. For example, in the second time interval of the fifth time interval (361) extending from the end time of the first time interval (362) of the fifth time interval (361), the third pixel data for the third color may be applied to the pixels of the pixel line following the first pixel line (e.g., the pixel line (300b) of FIG. 3a).

[0100] Referring to the B light emission (365) of the first example (330), the display driver IC (113) can control the third light emission circuit (203) using the light emission driver IC (117) to emit light of the third color for the pixels to which the third pixel data is applied within the sixth time interval (366). For example, the sixth time interval (366) can represent the time between a start time (366a) and an end time (366b). For example, the start time (366a) of the sixth time interval (366) can be a time before the end time (361b) of the fifth time interval (361). For example, the start time (366a) can be a time after the reference time (144) from the end time of the first time section (362). For example, the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color for the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 3A) to which third pixel data for the third color of the LCoS panel (115) is applied within the first time interval (367) within the sixth time interval (366). For example, the start time of the first time interval (367) may be the same as the start time (366a) of the sixth time interval (366). For example, the length of the first time interval (367) may be longer than or equal to the length of the first time interval (362). Although not shown in the first example (330), in each of the time sections within the sixth time interval (366), the display driver IC (113) can control the third light-emitting circuit (203) using the light-emitting driver IC (117) to sequentially emit light of the third color for each pixel of the pixel lines to which the third pixel data for the third color has been applied.For example, the display driver IC (113) can control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color with respect to the pixels of the second pixel line to which the third pixel data for the third color of the LCoS panel (115) is applied within the second time interval (368) of the sixth time interval (366). For example, the end time of the second time interval (368) can be the same as the end time (366b) of the sixth time interval (366).

[0101] The time intervals included in the time intervals for light emission of FIG. 3B (e.g., the second time interval (346), the fourth time interval (356), and the sixth time interval (366)) may have the same length or different lengths. For example, the length of each time interval within the time intervals for light emission may be changed depending on the properties of the image to be displayed (e.g., gradation, luminance).

[0102] Also, in FIG. 3b, a first example (330) is illustrated in which one R scan (340), one R flash (345), one G scan (350), one G flash (355), one B scan (360), and one B flash (365) is performed, but the present disclosure is not limited thereto. For example, the display driver IC (113) may perform one R scan (340), one R flash (345), one G scan (350), one G flash (355), one B scan (360), and one B flash (365) in order to display a different image within another frame following the frame of the first example (330) (e.g., the length from the start time (341a) to the end time (366b)). At this time, the sum of the lengths of the time intervals for the flashes within the frame may be equal to or different from the sum of the lengths of the time intervals for the flashes within the other frame. For example, the sum of the lengths of the time intervals for emitting light in each frame can be set differently depending on the characteristics of the light-emitting element.

[0103] Referring to FIG. 3b, compared to the example (130) in which local dimming driving is not performed, in the first example (330), light emission of a specific color may be performed before scanning of a specific color for pixels (or pixel lines) of the LCoS panel (115) is completed. A more specific example of performing light emission of the first color before scanning of the first color is completed according to the first example (330) may be referred to with reference to FIG. 3c below.

[0104] Example (370) of FIG. 3c illustrates an example of scanning and light emission performed on an LCoS panel (115) according to the first example (330) of local dimming driving of FIG. 3b. In example (370) of FIG. 3c, for convenience of explanation, a case of scanning and light emission for the first color is illustrated, but the present disclosure is not limited thereto.

[0105] Hereinafter, for convenience of explanation, it is assumed that the pixel lines of the LCoS panel (115) are composed of pixel lines extending from pixel line #1 (or the first pixel line) to pixel line #10 (or the second pixel line). However, the present disclosure is not limited thereto.

[0106] Referring to example (371), the display driver IC (113) can perform an R scan (340) on the LCoS panel (115). At this time, the R scan (340) can be sequentially performed on the pixels of the LCoS panel (115). For example, the display driver IC (113) can sequentially perform an R scan (340) on the pixels of pixel line #1 and then sequentially perform an R scan (340) on the pixels of pixel line #2.

[0107] Referring to Example (372), the display driver IC (113) may not perform R light emission (345) while the R scan (340) of Example (371) is performed. For example, the display driver IC (113) may control the first light emission circuit (201) using the light emission driver IC (117) to refrain from emitting light of the first color for all pixels of the LCoS panel (115) (i.e., pixels of pixel line #1 to pixel line #n). Example (372) may represent the same time as Example (371).

[0108] Referring to Example (373), which is a time after Example (371) (and Example (372)), the display driver IC (113) can perform an R scan (340) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform an R scan (340) on the pixels of pixel line #3 and then perform an R scan (340) on the pixels of pixel line #4.

[0109] Referring to example (374), the display driver IC (113) can perform R light emission (345). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color for the pixels of pixel line #1 and pixel line #2 while performing the R scan (340) for pixel line #3 and pixel line #4 in example (373). Example (374) can represent the same time as example (373). The time at which pixel line #1 starts to emit light can be a time after the reference time (144) from the time at which the scan for pixel line #1 is completed.

[0110] Referring to Example (375), which is a time after Example (373) (and Example (374)), the display driver IC (113) can perform an R scan (340) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform an R scan (340) on the pixels of pixel line #5 and then perform an R scan (340) on the pixels of pixel line #6.

[0111] Referring to example (376), the display driver IC (113) can perform R light emission (345). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color for the pixels of pixel line #3 and pixel line #4 while performing the R scan (340) for pixel line #5 and pixel line #6 in example (375). Example (376) can represent the same time as example (375). At this time, the light emission for pixel line #1 and pixel line #2 can be maintained according to the light emission time (e.g., the length of the first time section (347) of the second time interval (346) of FIG. 3B).

[0112] Referring to Example (377), which is a time after Example (375) (and Example (376)), the display driver IC (113) can perform an R scan (340) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform an R scan (340) on the pixels of pixel line #7 and then perform an R scan (340) on the pixels of pixel line #8.

[0113] Referring to example (378), the display driver IC (113) can perform R light emission (345). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color for the pixels of pixel line #5 and pixel line #6 while performing the R scan (340) for pixel line #7 and pixel line #8 in example (377). Example (378) can represent the same time as example (377). At this time, the light emission for pixel line #1 and pixel line #2 can be stopped according to the light emission time (e.g., the length of the first time section (347) of the second time interval (346) of FIG. 3B).

[0114] Referring to Example (379), which is a time after Example (377) (and Example (378)), the display driver IC (113) may perform an R scan (340) on the LCoS panel (115). For example, the display driver IC (113) may sequentially perform an R scan (340) on the pixels of pixel line #9 and then perform an R scan (340) on the pixels of pixel line #10. When the R scan (340) on the pixels of pixel line #10 is completed, the R scan (340) on the LCoS panel (115) may be stopped. In other words, the time at which the R scan (340) on the pixels of pixel line #10 is completed may be the end time (341b) of FIG. 3B.

[0115] Referring to example (380), the display driver IC (113) can perform R light emission (345). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color for the pixels of pixel line #7 and pixel line #8 while performing the R scan (340) for pixel line #9 and pixel line #10 in example (379). Example (380) can represent the same time as example (379). At this time, the light emission for pixel line #3 and pixel line #4 can be stopped according to the light emission time (e.g., the length of the first time section (347) of the second time interval (346) of FIG. 3B). The light emission for pixel line #5 and pixel line #6 can be maintained according to the light emission time.

[0116] Although not shown in example (370) of FIG. 3c, within the time period after example (380), the display driver IC (113) can sequentially perform R light emission (345) for pixel lines.

[0117] Figures 4a and 4b illustrate a second example of local dimming driving.

[0118] Fig. 4a illustrates a second example (430) of local dimming driving performed using the light source (120) of Fig. 2a and the LCoS panel (115) of Fig. 3a. The local dimming driving of the second example (430) may include performing a scan of a specific color (e.g., a G scan) different from the specific color while performing light emission of a specific color (e.g., R light emission).

[0119] A second example (430) illustrates a timing diagram in which an R scan (440), an R emission (445), a G scan (450), a G emission (455), a B scan (460), and a B emission (465) are performed. For example, the R scan (440) may represent the scan for applying pixel data for a first color to a pixel electrode. For example, the R emission (445) may include the emission for emitting light of the first color with respect to a pixel including a pixel electrode to which pixel data for the first color has been applied. For example, the G scan (450) may represent the scan for applying pixel data for a second color to a pixel electrode. For example, the G emission (455) may include the emission for emitting light of the second color with respect to a pixel including a pixel electrode to which pixel data for the second color has been applied. For example, B scan (460) may represent a scan for applying pixel data for a third color to a pixel electrode. For example, B emission (465) may include emission for emitting light of the third color with respect to a pixel including a pixel electrode to which pixel data for the third color has been applied.

[0120] Referring to the R scan (440) of the second example (430), the display driver IC (113) may apply the first pixel data for the first color to the pixels of the LCoS panel (115) within a first time interval (441). For example, the first time interval (441) may represent the time between a start time (441a) and an end time (441b). For example, the display driver IC (113) may apply the first pixel data for the first color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 3A) of the LCoS panel (115) within a first time section (442) within the first time interval (441). For example, the first time section (442) may extend from the start time (441a) of the first time interval (441). Although not illustrated in the second example (430), in each of the time sections within the first time interval (441), the display driver IC (113) may sequentially apply the first pixel data for the first color to the pixels of each pixel line. For example, in the second time section of the first time interval (441) extending from the end time of the first time section (442) of the first time interval (441), the first pixel data for the first color may be applied to the pixels of the pixel line following the first pixel line (e.g., the pixel line (300b) of FIG. 3A).

[0121] Referring to the R emission (445) of the second example (430), the display driver IC (113) can control the first emission circuit (201) using the emission driver IC (117) to emit light of the first color for the pixels to which the first pixel data is applied within a second time interval (446). For example, the second time interval (446) can represent a time between a start time (446a) and an end time (446b). For example, the start time (446a) of the second time interval (446) can be a time before the end time (441b) of the first time interval (441). For example, the start time (446a) can be a time after the reference time (144) from the end time of the first time section (442). For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 3A) to which the first pixel data for the first color of the LCoS panel (115) is applied within the first time interval (447) of the second time interval (446). For example, the start time of the first time interval (447) may be the same as the start time (446a) of the second time interval (446). For example, the length of the first time interval (447) may be longer than or equal to the length of the first time interval (442). Although not shown in the second example (430), in each of the time sections within the second time interval (446), the display driver IC (113) can control the first light-emitting circuit (201) using the light-emitting driver IC (117) to sequentially emit light of the first color for each pixel of the pixel lines to which the first pixel data for the first color has been applied.For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the second pixel line to which the first pixel data for the first color of the LCoS panel (115) is applied within the second time section (448) of the second time interval (446). For example, the end time of the second time section (448) may be the same as the end time (446b) of the second time interval (446). The second pixel line may represent the last pixel line among the pixel lines of the LCoS panel (115).

[0122] Referring to the G scan (450) of the second example (430), the display driver IC (113) can apply the second pixel data for the second color to the pixels of the LCoS panel (115) within a third time interval (451). For example, the third time interval (451) can represent a time between a start time (451a) and an end time (451b). For example, the start time (451a) of the third time interval (451) can be a time before the end time (446b) of the second time interval (446). For example, the start time (451a) of the third time interval (451) can be a time after the end time (441b) of the first time interval (441). For example, the display driver IC (113) may apply the second pixel data for the second color to the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 3A) of the LCoS panel (115) within a first time interval (452) within a third time interval (451). For example, the first time interval (452) may extend from the start time (451a) of the third time interval (451). Although not illustrated in the second example (430), in each of the time intervals within the third time interval (451), the display driver IC (113) may sequentially apply the second pixel data for the second color to the pixels of each of the pixel lines. For example, within a second time interval of a third time interval (451) extending from the end time of a first time interval (452) of a third time interval (451), second pixel data for the second color may be applied to pixels of a pixel line following the first pixel line (e.g., pixel line (300b) of FIG. 3A).

[0123] Referring to the G emission (455) of the second example (430), the display driver IC (113) can control the second emission circuit (202) using the emission driver IC (117) to emit light of the second color for the pixels to which the second pixel data is applied within the fourth time interval (456). For example, the fourth time interval (456) can represent the time between a start time (456a) and an end time (456b). For example, the start time (456a) of the fourth time interval (456) can be a time before the end time (451b) of the third time interval (451). For example, the start time (456a) can be a time after the reference time (144) from the end time of the first time section (452). Referring to the second example (430) illustrated in FIG. 4A, the start time (456a) of the fourth time interval (456) may be a time before the end time (446b) of the second time interval (446). However, the present disclosure is not limited thereto. For example, the start time (456a) of the fourth time interval (456) may be a time after the end time (446b) of the second time interval (446). For example, the display driver IC (113) may control the second light-emitting circuit (202) using the light-emitting driver IC (117) to emit light of the second color, with respect to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 3A) to which the second pixel data for the second color of the LCoS panel (115) is applied, within the first time section (457) within the fourth time interval (456). For example, the start time of the first time interval (457) may be the same as the start time (456a) of the fourth time interval (456). For example, the length of the first time interval (457) may be longer than or equal to the length of the first time interval (452).Although not illustrated in the second example (430), in each of the time sections within the fourth time interval (456), the display driver IC (113) may control the second light emitting circuit (202) using the light emitting driver IC (117) to sequentially emit light of the second color for each pixel of the pixel lines to which the second pixel data for the second color has been applied. For example, the display driver IC (113) may control the second light emitting circuit (202) using the light emitting driver IC (117) to emit light of the second color for each pixel of the second pixel line to which the second pixel data for the second color has been applied for the LCoS panel (115) within the second time section (458) of the fourth time interval (456). For example, the end time of the second time section (458) may be the same as the end time (456b) of the fourth time interval (456).

[0124] Referring to the B scan (460) of the second example (430), the display driver IC (113) may apply the third pixel data for the third color to the pixels of the LCoS panel (115) within a fifth time interval (461). For example, the fifth time interval (461) may represent a time between a start time (461a) and an end time (461b). For example, the start time (461a) of the fifth time interval (461) may be a time before the end time (456b) of the fourth time interval (456). For example, the start time (461a) of the fifth time interval (461) may be a time after the end time (451b) of the third time interval (451). For example, the display driver IC (113) may apply the third pixel data for the third color to the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 3A) of the LCoS panel (115) within a first time interval (462) within a fifth time interval (461). For example, the first time interval (462) may extend from the start time (461a) of the fifth time interval (461). Although not illustrated in the second example (430), in each of the time intervals within the fifth time interval (461), the display driver IC (113) may sequentially apply the third pixel data for the third color to the pixels of each of the pixel lines. For example, within a second time interval of a fifth time interval (461) extending from the end time of a first time interval (462) of a fifth time interval (461), third pixel data for the third color may be applied to pixels of a pixel line following the first pixel line (e.g., pixel line (300b) of FIG. 3A).

[0125] Referring to the B emission (465) of the second example (430), the display driver IC (113) can control the third emission circuit (203) using the emission driver IC (117) to emit light of the third color for the pixels to which the third pixel data is applied within the sixth time interval (466). For example, the sixth time interval (466) can represent the time between a start time (466a) and an end time (466b). For example, the start time (466a) of the sixth time interval (466) can be a time before the end time (461b) of the fifth time interval (461). For example, the start time (466a) can be a time after the reference time (144) from the end time of the first time section (462). Referring to the second example (430) illustrated in FIG. 4A, the start time (466a) of the sixth time interval (466) may be a time before the end time (456b) of the fourth time interval (456). However, the present disclosure is not limited thereto. For example, the start time (466a) of the sixth time interval (466) may be a time after the end time (456b) of the fourth time interval (456). For example, the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color, with respect to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 3A) to which the third pixel data for the third color of the LCoS panel (115) is applied, within the first time section (467) within the sixth time interval (466). For example, the start time of the first time interval (467) may be the same as the start time (466a) of the sixth time interval (466). For example, the length of the first time interval (467) may be longer than or equal to the length of the first time interval (462).Although not illustrated in the second example (430), in each of the time sections within the sixth time interval (466), the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to sequentially emit light of the third color for each pixel of the pixel lines to which the third pixel data for the third color has been applied. For example, the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color for each pixel of the second pixel line to which the third pixel data for the third color has been applied for the LCoS panel (115) within the second time section (468) of the sixth time interval (466). For example, the end time of the second time section (468) may be the same as the end time (466b) of the sixth time interval (466).

[0126] The time intervals included in the time intervals for light emission of FIG. 4A (e.g., the second time interval (446), the fourth time interval (456), and the sixth time interval (466)) may have the same length or different lengths. For example, the length of each time interval within the time intervals for light emission may be changed depending on the properties of the image to be displayed (e.g., grayscale, luminance).

[0127] Also, in FIG. 4A, a second example (430) is illustrated in which one R scan (440), one R flash (445), one G scan (450), one G flash (455), one B scan (460), and one B flash (465) is performed, but the present disclosure is not limited thereto. For example, the display driver IC (113) may perform one R scan (440), one R flash (445), one G scan (450), one G flash (455), one B scan (460), and one B flash (465) in order to display a different image within another frame following the frame of the second example (430) (e.g., the length from the start time (441a) to the end time (466b)). At this time, the sum of the lengths of the time intervals for the flashes within the frame may be equal to or different from the sum of the lengths of the time intervals for the flashes within the other frame. For example, the sum of the lengths of the time intervals for emitting light in each frame can be set differently depending on the characteristics of the light-emitting element.

[0128] Referring to FIG. 4a, compared to the example (130) in which local dimming driving is not performed, in the second example (430), light emission of a specific color may be performed before a scan of a specific color for pixels (or pixel lines) of the LCoS panel (115) is completed. Furthermore, in the second example (430), a scan of another specific color may be performed before the light emission of the specific color is completed. A more specific example of performing a scan of the second color before the light emission of the first color is completed according to the second example (430) may be referred to with reference to FIG. 4b below.

[0129] Example (470) of Fig. 4b illustrates an example of scanning and light emission performed on an LCoS panel (115) according to the second example (430) of local dimming driving of Fig. 4a. In example (470) of Fig. 4b, light emission for the first color, scan for the second color, and light emission for the second color are illustrated for convenience of explanation, but the present disclosure is not limited thereto. In example (470), it is assumed that the scan for the first color on the LCoS panel (115) has already been performed.

[0130] Hereinafter, for convenience of explanation, it is assumed that the pixel lines of the LCoS panel (115) are composed of pixel lines extending from pixel line #1 (or the first pixel line) to pixel line #10 (or the second pixel line). However, the present disclosure is not limited thereto.

[0131] Referring to example (471), the display driver IC (113) can perform a G scan (450) on the LCoS panel (115). At this time, the G scan (450) can be sequentially performed on the pixels of the LCoS panel (115). For example, the display driver IC (113) can sequentially perform a G scan (450) on the pixels of pixel line #1 and then sequentially perform a G scan (450) on the pixels of pixel line #2.

[0132] Referring to Example (472), the display driver IC (113) can perform R light emission (445) while the G scan (450) of Example (471) is performed. For example, the display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color with respect to pixels of pixel line #7, pixel line #8, pixel line #9, and pixel line #10 while performing the G scan (450) for pixel line #1 and pixel line #2 in Example (471). Example (472) can represent the same time as Example (471).

[0133] Referring to Example (473), which is a time after Example (471) (and Example (472)), the display driver IC (113) can perform a G scan (450) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform a G scan (450) on the pixels of pixel line #3 and then perform a G scan (450) on the pixels of pixel line #4.

[0134] Referring to Example (474), the display driver IC (113) can perform R light emission (445) and G light emission (455). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color with respect to pixels of pixel line #9 and pixel line #10 while performing the G scan (450) for pixel line #3 and pixel line #4 in Example (473). The display driver IC (113) can control the second light emission circuit (202) using the light emission driver IC (117) to emit light of the second color with respect to pixels of pixel line #1 and pixel line #2 while performing the G scan (450) for pixel line #3 and pixel line #4 in Example (473). Example (474) can represent the same time as Example (473). In the example (470) of FIG. 4b, a case is illustrated where R emission (445) and G emission (455) are performed simultaneously, but the present disclosure is not limited thereto. For example, G emission (455) may start after the time interval of R emission (445) (e.g., the first time interval (441) of FIG. 4a) ends.

[0135] Referring to Example (475), which is a time after Example (473) (and Example (474)), the display driver IC (113) can perform a G scan (450) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform a G scan (450) on the pixels of pixel line #5 and then perform a G scan (450) on the pixels of pixel line #6.

[0136] Referring to example (476), the display driver IC (113) can perform G light emission (455). The display driver IC (113) can control the second light emission circuit (202) using the light emission driver IC (117) to emit light of the second color for the pixels of pixel line #3 and pixel line #4 while performing the G scan (450) for pixel line #5 and pixel line #6 in example (475). Example (476) can represent the same time as example (475). At this time, the light emission for pixel line #1 and pixel line #2 can be maintained according to the light emission time (e.g., the length of the first time section (457) of the fourth time interval (456) of FIG. 4A).

[0137] Although not shown in example (470) of FIG. 4b, within the time period after example (476), the display driver IC (113) can sequentially perform G scan (450) and G emission (455) for pixel lines.

[0138] Figure 5a illustrates another example of pixels of an LCoS panel for local dimming driving.

[0139] FIG. 5A illustrates an example (500) of pixels included in a pixel array (116) of an LCoS panel (115). In the example (500), four pixels included in the pixel array (116) are illustrated, but this is merely an example for convenience of explanation, and the present disclosure is not limited thereto. The pixel array (116) illustrated in the example (500) of FIG. 5A may include at least a portion of the pixel array (116) of the example (300) of FIG. 3A. For example, the first pixel (301) of the example (500) of FIG. 5A may correspond to the first pixel (301) included in the pixel array (116) of the example (300).

[0140] Referring to example (500), the pixel array (116) may include a first pixel (301), a second pixel (302), a third pixel (303), and a fourth pixel (304). For example, the first pixel (301) and the second pixel (302) may constitute a pixel line (300a). For example, the third pixel (303) and the fourth pixel (304) may constitute a pixel line (300b) following (or consecutive to) the pixel line (300a). In example (500), each of the pixel line (300a) and the pixel line (300b) is illustrated as including two pixels, but the present disclosure is not limited thereto. For example, each pixel line may include three or more pixels.

[0141] For example, the first pixel (301) may include a pixel electrode (310), a first transistor (311), and a second transistor (511). For example, the pixel electrode (310) may be formed of metal for reflecting light provided from a light source (120). For example, the pixel electrode (310) may be formed of a metal plate or a metal thin film. For example, the first transistor (311) may include a gate electrode (311a) electrically connected to a first scan line (312) (e.g., Scan1-1), a first electrode (311b) electrically connected to a first data line (313) (e.g., Data1-1), and a second electrode (311c) electrically connected to the pixel electrode (310). For example, the first electrode (311b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode (311c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the second transistor (511) may include a gate electrode (511a) electrically connected to a second scan line (512) (e.g., Scan1-2), a third electrode (511b) electrically connected to a second data line (513) (e.g., Data1-2), and a fourth electrode (511c) electrically connected to the pixel electrode (310). For example, the third electrode (511b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the fourth electrode (511c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0142] For example, similar to the first pixel (301), the second pixel (302) may include a pixel electrode (314), a first transistor (315), and a second transistor (515). The specific details of the pixel electrode (314) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (315) may be substantially the same as those of the first transistor (311). For example, the first transistor (311) may be electrically connected to a first scan line (312) (e.g., Scan1-1) and a first data line (317) (e.g., Data2-1). The specific details of the second transistor (515) may be substantially the same as those of the second transistor (511). For example, the second transistor (515) may be electrically connected to a second scan line (512) (e.g., Scan1-2) and a second data line (517) (e.g., Data2-2).

[0143] Also, for example, similar to the first pixel (301), the third pixel (303) may include a pixel electrode (320), a first transistor (321), and a second transistor (521). The specific details of the pixel electrode (320) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (321) may be substantially the same as those of the first transistor (311). For example, the first transistor (321) may be electrically connected to a first scan line (322) (e.g., Scan2-1) and a first data line (313) (e.g., Data1-1). The specific details of the second transistor (521) may be substantially the same as those of the second transistor (511). For example, the second transistor (521) can be electrically connected to a second scan line (522) (e.g., Scan2-2) and a second data line (513) (e.g., Data1-2).

[0144] Also, for example, similar to the first pixel (301), the fourth pixel (304) may include a pixel electrode (324), a first transistor (325), and a second transistor (525). The specific details of the pixel electrode (324) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (325) may be substantially the same as those of the first transistor (311). For example, the first transistor (325) may be electrically connected to the first scan line (322) (e.g., Scan2-1) and the first data line (317) (e.g., Data2-1). The specific details of the second transistor (525) may be substantially the same as those of the second transistor (511). For example, the second transistor (525) may be electrically connected to a second scan line (522) (e.g., Scan2-2) and a second data line (517) (e.g., Data2-2).

[0145] For example, the display driver IC (113) can perform a scan for the first pixel (301). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (310) through the first data line (313) by providing a scan signal to the gate electrode (311a) of the first transistor (311) through the first scan line (312). For example, the display driver IC (113) can apply different pixel data (or data voltage) to the pixel electrode (310) through the second data line (513) by providing a scan signal to the gate electrode (511a) of the second transistor (511) through the second scan line (512). At this time, the pixel data applied through the first data line (313) may be data for a different color from the different pixel data applied through the second data line (513). For example, when the pixel data applied through the first data line (313) is pixel data for the first color, the other pixel data applied through the second data line (513) may be pixel data for the second color. Or, for example, when the pixel data applied through the first data line (313) is pixel data for the second color, the other pixel data applied through the second data line (513) may be pixel data for the third color. Or, for example, when the pixel data applied through the first data line (313) is pixel data for the third color, the other pixel data applied through the second data line (513) may be pixel data for the first color.Alternatively, for example, if the pixel data applied through the first data line (313) is pixel data for the first color, the other pixel data applied through the second data line (513) may be reference data (or reference pixel data). For example, the reference data may be used to reduce the response speed of the liquid crystal constituting the LCoS panel. For specific details related thereto, reference may be made to FIGS. 8A to 8C below.

[0146] For example, the display driver IC (113) can perform a scan for the second pixel (302). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (314) through the first data line (317) by providing a scan signal to the gate electrode of the first transistor (315) through the first scan line (312). For example, the display driver IC (113) can apply other pixel data (or data voltage) to the pixel electrode (314) through the second data line (517) by providing a scan signal to the gate electrode of the second transistor (515) through the second scan line (512). For example, the display driver IC (113) can perform a scan for the third pixel (303). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (320) through the first data line (313) by providing a scan signal to the gate electrode of the first transistor (321) through the first scan line (322). For example, the display driver IC (113) can apply other pixel data (or data voltage) to the pixel electrode (320) through the second data line (513) by providing a scan signal to the gate electrode of the second transistor (521) through the second scan line (522). For example, the display driver IC (113) can perform a scan on the fourth pixel (304). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (324) through the first data line (317) by providing a scan signal to the gate electrode of the first transistor (325) through the first scan line (322).For example, the display driver IC (113) can apply different pixel data (or data voltage) to the pixel electrode (324) through the second data line (517) by providing a scan signal to the gate electrode of the second transistor (525) through the second scan line (522).

[0147] As described above, a single scan line may be used to provide scan signals to pixels within a single pixel line (e.g., a row). A single data line may be used to apply pixel data to pixels arranged in a direction perpendicular to the pixel line (e.g., a column).

[0148] Figures 5b and 5c illustrate a third example of local dimming driving.

[0149] Fig. 5b illustrates a third example (530) of local dimming driving performed using the light source (120) of Fig. 2a and the LCoS panel (115) of Fig. 5a. The local dimming driving of the third example (530) may include performing a scan of a specific color (e.g., a G scan) different from the specific color while performing light emission of a specific color (e.g., R light emission).

[0150] A third example (530) illustrates a timing diagram in which an R scan (540), an R emission (545), a G scan (550), a G emission (555), a B scan (560), and a B emission (565) are performed. For example, the R scan (540) may represent the scan for applying pixel data for a first color to a pixel electrode. For example, the R emission (545) may include the emission for emitting light of the first color with respect to a pixel including a pixel electrode to which pixel data for the first color has been applied. For example, the G scan (550) may represent the scan for applying pixel data for a second color to a pixel electrode. For example, the G emission (555) may include the emission for emitting light of the second color with respect to a pixel including a pixel electrode to which pixel data for the second color has been applied. For example, B scan (560) may represent the scan for applying pixel data for a third color to a pixel electrode. For example, B emission (565) may include the emission for emitting light of the third color with respect to a pixel including a pixel electrode to which pixel data for the third color has been applied.

[0151] Referring to the R scan (540) of the third example (530), the display driver IC (113) may apply the first pixel data for the first color to the pixels of the LCoS panel (115) within a first time interval (541). For example, the first time interval (541) may represent the time between a start time (541a) and an end time (541b). For example, the display driver IC (113) may apply the first pixel data for the first color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 5A) of the LCoS panel (115) within a first time section (542) within the first time interval (541). For example, the first time section (542) may extend from the start time (541a) of the first time interval (541). Although not illustrated in the third example (530), in each of the time sections within the first time interval (541), the display driver IC (113) may sequentially apply the first pixel data for the first color to the pixels of each pixel line. For example, in the second time section of the first time interval (541) extending from the end time of the first time section (542) of the first time interval (541), the first pixel data for the first color may be applied to the pixels of the pixel line following the first pixel line (e.g., the pixel line (300b) of FIG. 5A).

[0152] Referring to the R emission (545) of the third example (530), the display driver IC (113) can control the first emission circuit (201) using the emission driver IC (117) to emit light of the first color for the pixels to which the first pixel data is applied within the second time interval (546). For example, the second time interval (546) can represent a time between a start time (546a) and an end time (546b). For example, the start time (546a) of the second time interval (546) can be a time before the end time (541b) of the first time interval (541). For example, the start time (546a) can be a time after the reference time (144) from the end time of the first time section (542). For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 5A) to which the first pixel data for the first color of the LCoS panel (115) is applied within the first time interval (547) of the second time interval (546). For example, the start time of the first time interval (547) may be the same as the start time (546a) of the second time interval (546). For example, the length of the first time interval (547) may be longer than or equal to the length of the first time interval (542). Although not shown in the third example (530), in each of the time sections within the second time interval (546), the display driver IC (113) can control the first light-emitting circuit (201) using the light-emitting driver IC (117) to sequentially emit light of the first color for each pixel of the pixel lines to which the first pixel data for the first color has been applied.For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the second pixel line to which the first pixel data for the first color of the LCoS panel (115) is applied within the second time section (548) of the second time interval (546). For example, the end time of the second time section (548) may be the same as the end time (546b) of the second time interval (546). The second pixel line may represent the last pixel line among the pixel lines of the LCoS panel (115).

[0153] Referring to the G scan (550) of the third example (530), the display driver IC (113) can apply the second pixel data for the second color to the pixels of the LCoS panel (115) within a third time interval (551). For example, the third time interval (551) can represent a time between a start time (551a) and an end time (551b). For example, the start time (551a) of the third time interval (551) can be a time before the end time (546b) of the second time interval (546). For example, the start time (551a) of the third time interval (551) can be a time before the end time (541b) of the first time interval (541). This is because each pixel includes two transistors, the G scan (550) can start even before the R scan (540) ends. For example, the display driver IC (113) may apply the second pixel data for the second color to the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 5A) of the LCoS panel (115) within a first time interval (552) within a third time interval (551). For example, the first time interval (552) may extend from a start time (551a) of the third time interval (551). For example, the first time interval (552) of the third time interval (551) may be a time after the first time interval (547) of the second time interval (546). Although not illustrated in the third example (530), in each of the time intervals within the third time interval (551), the display driver IC (113) may sequentially apply the second pixel data for the second color to the pixels of each of the pixel lines.For example, within a second time interval of a third time interval (551) extending from the end time of a first time interval (552) of a third time interval (551), second pixel data for the second color may be applied to pixels of a pixel line following the first pixel line (e.g., pixel line (300b) of FIG. 5A).

[0154] Referring to the G emission (555) of the third example (530), the display driver IC (113) can control the second emission circuit (202) using the emission driver IC (117) to emit light of the second color for the pixels to which the second pixel data is applied within the fourth time interval (556). For example, the fourth time interval (556) can represent the time between a start time (556a) and an end time (556b). For example, the start time (556a) of the fourth time interval (556) can be a time before the end time (551b) of the third time interval (551). For example, the start time (556a) can be a time after the reference time (144) from the end time of the first time section (552). Referring to the third example (530) illustrated in FIG. 5b, the start time (556a) of the fourth time interval (556) may be a time before the end time (546b) of the second time interval (546). However, the present disclosure is not limited thereto. For example, the start time (556a) of the fourth time interval (556) may be a time after the end time (546b) of the second time interval (546). For example, the display driver IC (113) may control the second light-emitting circuit (202) using the light-emitting driver IC (117) to emit light of the second color, with respect to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 5a) to which the second pixel data for the second color of the LCoS panel (115) is applied, within the first time section (557) within the fourth time interval (556). For example, the start time of the first time interval (557) may be the same as the start time (556a) of the fourth time interval (556). For example, the length of the first time interval (557) may be longer than or equal to the length of the first time interval (552).Although not illustrated in the third example (530), in each of the time sections within the fourth time interval (556), the display driver IC (113) may control the second light emitting circuit (202) using the light emitting driver IC (117) to sequentially emit light of the second color for each pixel of the pixel lines to which the second pixel data for the second color has been applied. For example, the display driver IC (113) may control the second light emitting circuit (202) using the light emitting driver IC (117) to emit light of the second color for each pixel of the second pixel line to which the second pixel data for the second color has been applied for the LCoS panel (115) within the second time section (558) of the fourth time interval (556). For example, the end time of the second time section (558) may be the same as the end time (556b) of the fourth time interval (556).

[0155] Referring to the B scan (560) of the third example (530), the display driver IC (113) may apply the third pixel data for the third color to the pixels of the LCoS panel (115) within a fifth time interval (561). For example, the fifth time interval (561) may represent a time between a start time (561a) and an end time (561b). For example, the start time (561a) of the fifth time interval (561) may be a time before the end time (556b) of the fourth time interval (556). For example, the start time (561a) of the fifth time interval (561) may be a time before the end time (551b) of the third time interval (551). Additionally, the start time (561a) of the fifth time interval (561) may be a time after the end time (541b) of the first time interval (541). This means that since each pixel includes two transistors, the B scan (560) can start even before the G scan (550) ends, and the B scan (560) can start after the R scan (540) ends. For example, the display driver IC (113) can apply the third pixel data for the third color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 5A) of the LCoS panel (115) within a first time interval (562) within a fifth time interval (561). For example, the first time interval (562) can be extended from the start time (561a) of the fifth time interval (561). For example, the first time interval (562) of the fifth time interval (561) can be a time after the first time interval (557) of the fourth time interval (556). Although not shown in the third example (530), in each of the time intervals within the fifth time interval (561), the display driver IC (113) can sequentially apply third pixel data for the third color to each pixel of each pixel line.For example, within a second time interval of a fifth time interval (561) extending from the end time of a first time interval (562) of a fifth time interval (561), third pixel data for the third color may be applied to pixels of a pixel line following the first pixel line (e.g., pixel line (300b) of FIG. 5A).

[0156] Referring to the B emission (565) of the third example (530), the display driver IC (113) can control the third emission circuit (203) using the emission driver IC (117) to emit light of the third color for the pixels to which the third pixel data is applied within the sixth time interval (566). For example, the sixth time interval (566) can represent the time between a start time (566a) and an end time (566b). For example, the start time (566a) of the sixth time interval (566) can be a time before the end time (561b) of the fifth time interval (561). For example, the start time (566a) can be a time after the reference time (144) from the end time of the first time section (562). Referring to the third example (530) illustrated in FIG. 5b, the start time (566a) of the sixth time interval (566) may be a time before the end time (556b) of the fourth time interval (556). However, the present disclosure is not limited thereto. For example, the start time (566a) of the sixth time interval (566) may be a time after the end time (556b) of the fourth time interval (556). For example, the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color, with respect to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 5a) to which the third pixel data for the third color of the LCoS panel (115) is applied, within the first time section (567) within the sixth time interval (566). For example, the start time of the first time interval (567) may be the same as the start time (566a) of the sixth time interval (566). For example, the length of the first time interval (567) may be longer than or equal to the length of the first time interval (562).Although not illustrated in the third example (530), in each of the time sections within the sixth time interval (566), the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to sequentially emit light of the third color for each pixel of the pixel lines to which the third pixel data for the third color has been applied. For example, the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color for each pixel of the second pixel line to which the third pixel data for the third color has been applied for the LCoS panel (115) within the second time section (568) of the sixth time interval (566). For example, the end time of the second time section (568) may be the same as the end time (566b) of the sixth time interval (566).

[0157] The time intervals included in the time intervals for light emission of FIG. 5b (e.g., the second time interval (546), the fourth time interval (556), and the sixth time interval (566)) may have the same length or different lengths. For example, the length of each time interval within the time interval for light emission may be changed depending on the properties of the image to be displayed (e.g., grayscale, luminance).

[0158] Also, in FIG. 5b, a third example (530) is illustrated in which one R scan (540), one R flash (545), one G scan (550), one G flash (555), one B scan (560), and one B flash (565) are performed, but the present disclosure is not limited thereto. For example, the display driver IC (113) may perform one R scan (540), one R flash (545), one G scan (550), one G flash (555), one B scan (560), and one B flash (565) in order to display a different image within another frame following the frame of the third example (530) (e.g., the length from the start time (541a) to the end time (566b)). At this time, the sum of the lengths of the time intervals for the flashes within the frame may be equal to or different from the sum of the lengths of the time intervals for the flashes within the other frame. For example, the sum of the lengths of the time intervals for emitting light in each frame can be set differently depending on the characteristics of the light-emitting element.

[0159] Referring to FIG. 5b, compared to the example (130) in which local dimming driving is not performed, in the third example (530), light emission of a specific color may be performed before a scan of a specific color for pixels (or pixel lines) of the LCoS panel (115) is completed. Furthermore, in the third example (530), a scan of another specific color may be performed before the scan of the specific color is completed. A more specific example of performing a scan of the second color before the scan of the first color is completed according to the third example (530) may be referred to with reference to FIG. 5c below.

[0160] Example (570) of FIG. 5c illustrates an example of scanning and light emission performed on an LCoS panel (115) according to the third example (530) of local dimming driving of FIG. 5b. For convenience of explanation, example (570) of FIG. 5c illustrates a case of scanning for the first color, light emission for the first color, scanning for the second color, and light emission for the second color, but the present disclosure is not limited thereto.

[0161] Hereinafter, for convenience of explanation, it is assumed that the pixel lines of the LCoS panel (115) are composed of pixel lines extending from pixel line #1 (or the first pixel line) to pixel line #10 (or the second pixel line). However, the present disclosure is not limited thereto.

[0162] Referring to example (571), the display driver IC (113) can perform an R scan (540) and a G scan (550) on the LCoS panel (115). At this time, the R scan (540) can be sequentially performed on the pixels of the LCoS panel (115). For example, the display driver IC (113) can sequentially perform the R scan (540) on the pixels of pixel line #9 and then sequentially perform the R scan (540) on the pixels of pixel line #10. The G scan (550) can be sequentially performed on the pixels of the LCoS panel (115). For example, the display driver IC (113) can sequentially perform the G scan (550) on the pixels of pixel line #1 and then sequentially perform the G scan (550) on the pixels of pixel line #2. In one example, the R scan (540) for the pixels in pixel line #9 and the G scan (550) for the pixels in pixel line #1 can be performed simultaneously, and the R scan (540) for the pixels in pixel line #10 and the G scan (550) for the pixels in pixel line #2 can be performed simultaneously. This may be because each pixel includes two transistors.

[0163] Referring to Example (572), the display driver IC (113) can perform R light emission (545) while the R scan (540) and G scan (550) of Example (571) are performed. For example, the display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color for pixels of pixel line #3, pixel line #4, pixel line #5, and pixel line #6 while performing the R scan (540) for pixel line #9 and pixel line #10, and the G scan (550) for pixel line #1 and pixel line #2 in Example (571). Example (572) can represent the same time as Example (571).

[0164] Referring to Example (573), which is a time after Example (571) (and Example (572)), the display driver IC (113) can perform a G scan (550) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform a G scan (550) on the pixels of pixel line #3 and then perform a G scan (550) on the pixels of pixel line #4.

[0165] Referring to Example (574), the display driver IC (113) can perform R light emission (545) and G light emission (555). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color with respect to pixels of pixel line #5, pixel line #6, pixel line #7, and pixel line #8 while performing the G scan (550) for pixel line #3 and pixel line #4 in Example (573). The display driver IC (113) can control the second light emission circuit (202) using the light emission driver IC (117) to emit light of the second color with respect to pixels of pixel line #1 and pixel line #2 while performing the G scan (550) for pixel line #3 and pixel line #4 in Example (573). Example (574) can represent the same time as Example (573). In the example (570) of FIG. 5c, a case is shown where R emission (545) and G emission (555) are performed simultaneously, but the present disclosure is not limited thereto.

[0166] Referring to Example (575), which is a time after Example (573) (and Example (574)), the display driver IC (113) can perform a G scan (550) on the LCoS panel (115). For example, the display driver IC (113) can sequentially perform a G scan (550) on the pixels of pixel line #5 and then perform a G scan (550) on the pixels of pixel line #6.

[0167] Referring to example (576), the display driver IC (113) can perform R light emission (545) and G light emission (555). The display driver IC (113) can control the first light emission circuit (201) using the light emission driver IC (117) to emit light of the first color with respect to pixels of pixel line #7, pixel line #8, pixel line #9, and pixel line #10 while performing the G scan (550) for pixel line #5 and pixel line #6 in example (575). The display driver IC (113) can control the second light emission circuit (202) using the light emission driver IC (117) to emit light of the second color with respect to pixels of pixel line #1, pixel line #2, pixel line #3, and pixel line #4 while performing the G scan (550) for pixel line #5 and pixel line #6 in example (575). Example (576) may represent the same time as example (575). In example (570) of Fig. 5c, a case is shown where R emission (545) and G emission (555) are performed simultaneously, but the present disclosure is not limited thereto.

[0168] Although not illustrated in the example (570) of FIG. 5c, within the time period after example (576), the display driver IC (113) may sequentially perform R emission (545) for pixel lines, G scan (550) for pixel lines, and G emission (555) for pixel lines. Although not illustrated in FIG. 5c, for pixel lines where the R scan (540) is completed and G emission (555) is terminated, the display driver IC (113) may also start B scan (560), as in the third example (530) of FIG. 5b. This may be because each pixel includes two transistors.

[0169] FIG. 6a illustrates another example of pixels of an LCoS panel for local dimming driving.

[0170] FIG. 6A illustrates an example (600) of pixels included in a pixel array (116) of an LCoS panel (115). In the example (600), four pixels are illustrated in the pixel array (116), but this is merely an example for convenience of explanation, and the present disclosure is not limited thereto. The pixel array (116) illustrated in the example (600) of FIG. 6A may include at least a portion of the pixel array (116) of the example (300) of FIG. 3A. Furthermore, the pixel array (116) illustrated in the example (600) of FIG. 6A may include at least a portion of the pixel array (116) of the example (500) of FIG. 5A. For example, the first pixel (301) of the example (600) of FIG. 6A may correspond to the first pixel (301) included in the pixel array (116) of the example (300). For example, the second transistor (511) of the example (600) of FIG. 6a may correspond to the second transistor (511) included in the pixel array (116) of the example (500).

[0171] Referring to example (600), the pixel array (116) may include a first pixel (301), a second pixel (302), a third pixel (303), and a fourth pixel (304). For example, the first pixel (301) and the second pixel (302) may constitute a pixel line (300a). For example, the third pixel (303) and the fourth pixel (304) may constitute a pixel line (300b) following (or consecutive to) the pixel line (300a). In example (600), each of the pixel line (300a) and the pixel line (300b) is illustrated as including two pixels, but the present disclosure is not limited thereto. For example, each pixel line may include three or more pixels.

[0172] For example, the first pixel (301) may include a pixel electrode (310), a first transistor (311), a second transistor (511), and a third transistor (611). For example, the pixel electrode (310) may be formed of a metal for reflecting light provided from a light source (120). For example, the pixel electrode (310) may be formed of a metal plate or a metal thin film. For example, the first transistor (311) may include a gate electrode (311a) electrically connected to a first scan line (312) (e.g., Scan1-1), a first electrode (311b) electrically connected to a first data line (313) (e.g., Data1-1), and a second electrode (311c) electrically connected to the pixel electrode (310). For example, the first electrode (311b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode (311c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the second transistor (511) may include a gate electrode (511a) electrically connected to a second scan line (512) (e.g., Scan1-2), a third electrode (511b) electrically connected to a second data line (513) (e.g., Data1-2), and a fourth electrode (511c) electrically connected to the pixel electrode (310). For example, the third electrode (511b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the fourth electrode (511c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the third transistor (611) may include a gate electrode (611a) electrically connected to a third scan line (612) (e.g., Scan1-3), a fifth electrode (611b) electrically connected to a third data line (613) (e.g., Data1-3), and a sixth electrode (611c) electrically connected to a pixel electrode (310).For example, the fifth electrode (611b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the sixth electrode (611c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0173] For example, similar to the first pixel (301), the second pixel (302) may include a pixel electrode (314), a first transistor (315), a second transistor (515), and a third transistor (615). The specific details of the pixel electrode (314) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (315) may be substantially the same as those of the first transistor (311). For example, the first transistor (311) may be electrically connected to a first scan line (312) (e.g., Scan1-1) and a first data line (317) (e.g., Data2-1). The specific details of the second transistor (515) may be substantially the same as those of the second transistor (511). For example, the second transistor (515) may be electrically connected to the second scan line (512) (e.g., Scan1-2) and the second data line (517) (e.g., Data2-2). The specific details of the third transistor (615) may be substantially identical to the details of the third transistor (611). For example, the third transistor (615) may be electrically connected to the third scan line (612) (e.g., Scan1-3) and the third data line (617) (e.g., Data2-3).

[0174] Also, for example, similar to the first pixel (301), the third pixel (303) may include a pixel electrode (320), a first transistor (321), a second transistor (521), and a third transistor (621). The specific details of the pixel electrode (320) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (321) may be substantially the same as those of the first transistor (311). For example, the first transistor (321) may be electrically connected to a first scan line (322) (e.g., Scan2-1) and a first data line (313) (e.g., Data1-1). The specific details of the second transistor (521) may be substantially the same as those of the second transistor (511). For example, the second transistor (521) may be electrically connected to the second scan line (522) (e.g., Scan2-2) and the second data line (513) (e.g., Data1-2). Specific details regarding the third transistor (621) may be substantially identically applied to the details regarding the third transistor (611). For example, the third transistor (621) may be electrically connected to the third scan line (622) (e.g., Scan2-3) and the third data line (613) (e.g., Data1-3).

[0175] Also, for example, similar to the first pixel (301), the fourth pixel (304) may include a pixel electrode (324), a first transistor (325), a second transistor (525), and a third transistor (625). The specific details of the pixel electrode (324) may be substantially the same as those of the pixel electrode (310). The specific details of the first transistor (325) may be substantially the same as those of the first transistor (311). For example, the first transistor (325) may be electrically connected to the first scan line (322) (e.g., Scan2-1) and the first data line (317) (e.g., Data2-1). The specific details of the second transistor (525) may be substantially the same as those of the second transistor (511). For example, the second transistor (525) may be electrically connected to the second scan line (522) (e.g., Scan2-2) and the second data line (517) (e.g., Data2-2). The specific details of the third transistor (625) may be substantially identical to the details of the third transistor (611). For example, the third transistor (625) may be electrically connected to the third scan line (622) (e.g., Scan2-3) and the third data line (617) (e.g., Data2-3).

[0176] For example, the display driver IC (113) can perform a scan for the first pixel (301). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (310) through the first data line (313) by providing a scan signal to the gate electrode (311a) of the first transistor (311) through the first scan line (312). For example, the display driver IC (113) can apply other pixel data (or data voltage) to the pixel electrode (310) through the second data line (513) by providing a scan signal to the gate electrode (511a) of the second transistor (511) through the second scan line (512). For example, the display driver IC (113) can apply another pixel data (or data voltage) to the pixel electrode (310) through the third data line (613) by providing a scan signal to the gate electrode (611a) of the third transistor (611) through the third scan line (612). At this time, the pixel data applied through the first data line (313), the other pixel data applied through the second data line (513), and the other pixel data applied through the third data line (613) may be data for different colors. For example, the pixel data applied through the first data line (313) may be pixel data for the first color, the other pixel data applied through the second data line (513) may be pixel data for the second color, and the other pixel data applied through the third data line (613) may be pixel data for the third color.

[0177] For example, the display driver IC (113) can perform a scan for the second pixel (302). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (314) through the first data line (317) by providing a scan signal to the gate electrode of the first transistor (315) through the first scan line (312). For example, the display driver IC (113) can apply other pixel data (or data voltage) to the pixel electrode (314) through the second data line (517) by providing a scan signal to the gate electrode of the second transistor (515) through the second scan line (512). For example, the display driver IC (113) can apply another pixel data (or data voltage) to the pixel electrode (314) through the third data line (617) by providing a scan signal to the gate electrode of the third transistor (615) through the third scan line (612). For example, the display driver IC (113) can perform a scan for the third pixel (303). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (320) through the first data line (313) by providing a scan signal to the gate electrode of the first transistor (321) through the first scan line (322). For example, the display driver IC (113) can apply different pixel data (or data voltage) to the pixel electrode (320) through the second data line (513) by providing a scan signal to the gate electrode of the second transistor (521) through the second scan line (522).For example, the display driver IC (113) can apply another pixel data (or data voltage) to the pixel electrode (320) through the third data line (613) by providing a scan signal to the gate electrode of the third transistor (621) through the third scan line (622). For example, the display driver IC (113) can perform a scan for the fourth pixel (304). For example, the display driver IC (113) can apply pixel data (or data voltage) to the pixel electrode (324) through the first data line (317) by providing a scan signal to the gate electrode of the first transistor (325) through the first scan line (322). For example, the display driver IC (113) can apply different pixel data (or data voltage) to the pixel electrode (324) through the second data line (517) by providing a scan signal to the gate electrode of the second transistor (525) through the second scan line (522). For example, the display driver IC (113) can apply different pixel data (or data voltage) to the pixel electrode (324) through the third data line (617) by providing a scan signal to the gate electrode of the third transistor (625) through the third scan line (622).

[0178] As described above, a single scan line may be used to provide scan signals to pixels within a single pixel line (e.g., a row). A single data line may be used to apply pixel data to pixels arranged in a direction perpendicular to the pixel line (e.g., a column).

[0179] Fig. 6b illustrates a fourth example of local dimming driving.

[0180] Fig. 6b illustrates a fourth example (630) of local dimming driving performed using the light source (120) of Fig. 2a and the LCoS panel (115) of Fig. 6a. The local dimming driving of the fourth example (630) may include performing a scan of a specific color (e.g., a G scan) different from the specific color while performing light emission of a specific color (e.g., R light emission).

[0181] A fourth example (630) illustrates a timing diagram in which an R scan (640), an R emission (645), a G scan (650), a G emission (655), a B scan (660), and a B emission (665) are performed. For example, the R scan (640) may represent the scan for applying pixel data for a first color to a pixel electrode. For example, the R emission (645) may include the emission for emitting light of the first color with respect to a pixel including a pixel electrode to which pixel data for the first color has been applied. For example, the G scan (650) may represent the scan for applying pixel data for a second color to a pixel electrode. For example, the G emission (655) may include the emission for emitting light of the second color with respect to a pixel including a pixel electrode to which pixel data for the second color has been applied. For example, B scan (660) may represent the scan for applying pixel data for a third color to a pixel electrode. For example, B emission (665) may include the emission for emitting light of the third color with respect to a pixel including a pixel electrode to which pixel data for the third color has been applied.

[0182] Referring to the R scan (640) of the fourth example (630), the display driver IC (113) may apply the first pixel data for the first color to the pixels of the LCoS panel (115) within a first time interval (641). For example, the first time interval (641) may represent the time between a start time (641a) and an end time (641b). For example, the display driver IC (113) may apply the first pixel data for the first color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 6A) of the LCoS panel (115) within a first time section (642) within the first time interval (641). For example, the first time section (642) may extend from the start time (641a) of the first time interval (641). Although not illustrated in the fourth example (630), in each of the time sections within the first time interval (641), the display driver IC (113) may sequentially apply the first pixel data for the first color to the pixels of each pixel line. For example, in the second time section of the first time interval (641) extending from the end time of the first time section (642) of the first time interval (641), the first pixel data for the first color may be applied to the pixels of the pixel line following the first pixel line (e.g., the pixel line (300b) of FIG. 6A).

[0183] Referring to the R emission (645) of the fourth example (630), the display driver IC (113) can control the first emission circuit (201) using the emission driver IC (117) to emit light of the first color for the pixels to which the first pixel data is applied within the second time interval (646). For example, the second time interval (646) can represent a time between a start time (646a) and an end time (646b). For example, the start time (646a) of the second time interval (646) can be a time before the end time (641b) of the first time interval (641). For example, the start time (646a) can be a time after the reference time (144) from the end time of the first time section (642). For example, the display driver IC (113) may control the first light-emitting circuit (201) using the light-emitting driver IC (117) to emit light of the first color for the pixels of the first pixel line (e.g., pixel line (300a) of FIG. 6A) to which the first pixel data for the first color of the LCoS panel (115) is applied within the first time interval (647) of the second time interval (646). For example, the start time of the first time interval (647) may be the same as the start time (646a) of the second time interval (646). For example, the length of the first time interval (647) may be longer than or equal to the length of the first time interval (642). Although not shown in the fourth example (630), in each of the time sections within the second time interval (646), the display driver IC (113) can control the first light-emitting circuit (201) using the light-emitting driver IC (117) to sequentially emit light of the first color for each pixel of the pixel lines to which the first pixel data for the first color has been applied.

[0184] Referring to the G scan (650) of the fourth example (630), the display driver IC (113) may apply the second pixel data for the second color to the pixels of the LCoS panel (115) within a third time interval (651). For example, the third time interval (651) may represent a time between a start time (651a) and an end time (651b). For example, the start time (651a) of the third time interval (651) may be a time before the end time (646b) of the second time interval (646). For example, the start time (651a) of the third time interval (651) may be a time before the end time (641b) of the first time interval (641). For example, the start time (651a) of the third time interval (651) may be a time after the end time of the first time section (647) of the second time interval (646). This is because the G scan (650) may start even before the R scan (640) ends, since each pixel includes three transistors. For example, the display driver IC (113) may apply the second pixel data for the second color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 6A) of the LCoS panel (115) within the first time section (652) within the third time interval (651). For example, the first time section (652) may extend from the start time (651a) of the third time interval (651). Although not shown in the fourth example (630), in each of the time intervals within the third time interval (651), the display driver IC (113) can sequentially apply second pixel data for the second color to each pixel of each pixel line.For example, within a second time interval of a third time interval (651) extending from the end time of a first time interval (652) of a third time interval (651), second pixel data for the second color may be applied to pixels of a pixel line following the first pixel line (e.g., pixel line (300b) of FIG. 6A).

[0185] Referring to the G emission (655) of the fourth example (630), the display driver IC (113) can control the second emission circuit (202) using the emission driver IC (117) to emit light of the second color for the pixels to which the second pixel data is applied within the fourth time interval (656). For example, the fourth time interval (656) can represent the time between a start time (656a) and an end time (656b). For example, the start time (656a) of the fourth time interval (656) can be a time before the end time (651b) of the third time interval (651). For example, the start time (656a) can be a time after the reference time (144) from the end time of the first time section (652). Referring to the fourth example (630) illustrated in FIG. 6b, the start time (656a) of the fourth time interval (656) may be a time before the end time (646b) of the second time interval (646). For example, the display driver IC (113) may control the second light-emitting circuit (202) using the light-emitting driver IC (117) to emit light of the second color for the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 6a) to which the second pixel data for the second color of the LCoS panel (115) is applied, within a first time section (657) within the fourth time interval (656). For example, the start time of the first time section (657) may be the same as the start time (656a) of the fourth time interval (656). For example, the length of the first time interval (657) may be longer than or equal to the length of the first time interval (652).Although not shown in the fourth example (630), in each of the time sections within the fourth time interval (656), the display driver IC (113) can control the second light emitting circuit (202) using the light emitting driver IC (117) to sequentially emit light of the second color for each pixel of the pixel lines to which the second pixel data for the second color has been applied.

[0186] Referring to the B scan (660) of the fourth example (630), the display driver IC (113) may apply the third pixel data for the third color to the pixels of the LCoS panel (115) within a fifth time interval (661). For example, the fifth time interval (661) may represent a time between a start time (661a) and an end time (661b). For example, the start time (661a) of the fifth time interval (661) may be a time before the end time (656b) of the fourth time interval (656). For example, the start time (661a) of the fifth time interval (661) may be a time before the end time (651b) of the third time interval (651). Additionally, the start time (661a) of the fifth time interval (661) may be a time before the end time (641b) of the first time interval (641). Additionally, the start time (661a) of the fifth time interval (661) may be a time after the end time of the first time section (657) of the fourth time interval (656). This is because the B scan (660) may start even before the R scan (640) and the G scan (650) end, since each pixel includes three transistors. For example, the display driver IC (113) may apply the third pixel data for the third color to the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 6A) of the LCoS panel (115) within the first time section (662) within the fifth time interval (661). For example, the first time section (662) may be extended from the start time (661a) of the fifth time interval (661). Although not shown in the fourth example (630), in each of the time intervals within the fifth time interval (661), the display driver IC (113) can sequentially apply third pixel data for the third color to each pixel of each pixel line.For example, within a second time interval of a fifth time interval (661) extending from the end time of a first time interval (662) of a fifth time interval (661), third pixel data for the third color may be applied to pixels of a pixel line following the first pixel line (e.g., pixel line (300b) of FIG. 6A).

[0187] Referring to the B emission (665) of the fourth example (630), the display driver IC (113) can control the third emission circuit (203) using the emission driver IC (117) to emit light of the third color for the pixels to which the third pixel data is applied within the sixth time interval (666). For example, the sixth time interval (666) can represent the time between a start time (666a) and an end time (666b). For example, the start time (666a) of the sixth time interval (666) can be a time before the end time (661b) of the fifth time interval (661). For example, the start time (666a) can be a time after the reference time (144) from the end time of the first time section (662). Referring to the fourth example (630) illustrated in FIG. 6b, the start time (666a) of the sixth time interval (666) may be a time before the end time (656b) of the fourth time interval (656). For example, the display driver IC (113) may control the third light-emitting circuit (203) using the light-emitting driver IC (117) to emit light of the third color for the pixels of the first pixel line (e.g., the pixel line (300a) of FIG. 6a) to which the third pixel data for the third color of the LCoS panel (115) is applied, within a first time section (667) within the sixth time interval (666). For example, the start time of the first time section (667) may be the same as the start time (666a) of the sixth time interval (666). For example, the length of the first time interval (667) may be longer than or equal to the length of the first time interval (662).Although not shown in the fourth example (630), in each of the time sections within the sixth time interval (666), the display driver IC (113) can control the third light-emitting circuit (203) using the light-emitting driver IC (117) to sequentially emit light of the third color for each pixel of the pixel lines to which the third pixel data for the third color has been applied.

[0188] The time intervals included in the time intervals for light emission of FIG. 6B (e.g., the second time interval (646), the fourth time interval (656), and the sixth time interval (666)) may have the same length or different lengths. For example, the length of each time interval within the time intervals for light emission may be changed depending on the properties of the image to be displayed (e.g., grayscale, luminance).

[0189] Also, in FIG. 6b, a fourth example (630) is illustrated in which one R scan (640), one R flash (645), one G scan (650), one G flash (655), one B scan (660), and one B flash (665) are performed, but the present disclosure is not limited thereto. For example, the display driver IC (113) may perform one R scan (640), one R flash (645), one G scan (650), one G flash (655), one B scan (660), and one B flash (665) in order to display a different image within another frame following the frame of the fourth example (630) (e.g., the length from the start time (641a) to the end time (666b)). At this time, the sum of the lengths of the time intervals for the flashes within the frame may be equal to or different from the sum of the lengths of the time intervals for the flashes within the other frame. For example, the sum of the lengths of the time intervals for emitting light in each frame can be set differently depending on the characteristics of the light-emitting element.

[0190] Referring to FIG. 6b, compared to the example (130) in which local dimming operation is not performed, in the fourth example (630), light emission of a specific color can be performed before a scan of a specific color for pixels (or pixel lines) of the LCoS panel (115) is completed. Furthermore, in the fourth example (630), scans of other specific colors can be performed before the scan of the specific color is completed.

[0191] FIGS. 7A to 7D illustrate examples of frame lengths according to the first, second, third, and fourth examples of local dimming driving.

[0192] Fig. 7a illustrates the length of a frame (709) according to the example (130) of Fig. 1b and a frame (719) according to the first example (330) of Fig. 3b. In Fig. 7a, for convenience of explanation, it is assumed that the pixel array (116) (or pixels) of the LCoS panel (115) is implemented with n pixel lines (e.g., pixel line #1 to pixel line #n).

[0193] Referring to example (130) of FIG. 7A, within a frame (709), an R scan (701), an R emission (702), a G scan (703), a G emission (704), a B scan (705), and a B emission (706) may be performed. The R emission (702) may be performed simultaneously for all pixels within the pixel array (116) of the LCoS panel (115). For example, the R emission (702) may be started after a reference time (144) from the end time of the R scan (701). For example, the G scan (703) may be performed after the R emission (702). The G emission (704) may be performed simultaneously for all pixels within the pixel array (116) of the LCoS panel (115). For example, the G emission (704) may be started after a reference time (144) from the end time of the G scan (703). For example, the B scan (705) may be performed after the G emission (704). The B emission (706) may be performed simultaneously for all pixels in the pixel array (116) of the LCoS panel (115). For example, the B emission (706) may be started after a reference time (144) from the end time of the B scan (705).

[0194] Referring to the first example (330) of FIG. 7a, within a frame (719), an R scan (711), an R emission (712), a G scan (713), a G emission (714), a B scan (715), and a B emission (716) may be performed. The R emission (712) may be sequentially performed for pixel lines within the pixel array (116) of the LCoS panel (115). For example, a time interval (712a) of the R emission (712) for pixel line #1 may start after a reference time (144) from the end time of the time interval (711a) of the R scan (711) for pixel line #1. The R emission (712) for pixel line #2 may be performed after the end time of the time interval (712a) of the R emission (712) for pixel line #1. The start time of the time interval (713a) of the G scan (713) for pixel line #1 may be performed after the R emission (712) ends. The G emission (714) may be sequentially performed for the pixel lines in the pixel array (116) of the LCoS panel (115). For example, the time interval (714a) of the G emission (714) for pixel line #1 may be started after the reference time (144) from the end time of the time interval (713a) of the G scan (713) for pixel line #1. The G emission (714) for pixel line #2 may be performed after the end time of the time interval (714a) of the G emission (714) for pixel line #1. The start time of the time interval (715a) of the B scan (715) for pixel line #1 may be performed after the end of the G emission (714). B emission (716) can be sequentially performed for pixel lines within the pixel array (116) of the LCoS panel (115). For example, a time interval (716a) of B emission (716) for pixel line #1 can start after a reference time (144) from the end time of a time interval (715a) of B scan (715) for pixel line #1.The B emission (716) for pixel line #2 can be performed after the end time of the time interval (716a) of the B emission (716) for pixel line #1.

[0195] Referring to FIG. 7A, the length of the frame (719) according to the first example (330) may be longer than the length of the frame (709) of the example (130). Since the local dimming driving according to the first example (330) sequentially performs light emission for each pixel line, the length of the frame (719) may be substantially longer. Accordingly, the local dimming driving according to the first example (330) may have a lower driving frequency compared to the example (130) that does not use the local dimming driving. In the first example (330) of FIG. 7A, a case is illustrated where all pixel lines light up, but the present disclosure is not limited thereto. For example, in the first example (330), only some pixel lines of the LCoS panel (115) may light up. Accordingly, the local dimming drive according to the first example (330) can reduce power consumption compared to the example (130) that does not use local dimming drive.

[0196] Fig. 7b illustrates a frame (729) according to the second example (430) of Fig. 4a. In Fig. 7b, for convenience of explanation, it is assumed that the pixel array (116) (or pixels) of the LCoS panel (115) is implemented with n pixel lines (e.g., pixel line #1 to pixel line #n).

[0197] Referring to the second example (430) of FIG. 7B, within a frame (729), an R scan (721), an R emission (722), a G scan (723), a G emission (724), a B scan (725), and a B emission (726) may be performed. The R emission (722) may be sequentially performed for pixel lines within the pixel array (116) of the LCoS panel (115). For example, a time interval (722a) of the R emission (722) for pixel line #1 may start after a reference time (144) from the end time of the time interval (721a) of the R scan (721) for pixel line #1. The R emission (722) for pixel line #2 may be performed after the end time of the time interval (722a) of the R emission (722) for pixel line #1. The start time of the time interval (723a) of the G scan (723) for pixel line #1 can be performed before the end time of the R emission (722). For example, the start time of the time interval (723a) of the G scan (723) for pixel line #1 can be performed before the end time of the time interval (722b) of the R emission (722) for pixel line #n. The G emission (724) can be sequentially performed for the pixel lines in the pixel array (116) of the LCoS panel (115). For example, the time interval (724a) of the G emission (724) for pixel line #1 can be started after the reference time (144) from the end time of the time interval (723a) of the G scan (723) for pixel line #1. The G emission (724) for pixel line #2 may be performed after the end time of the time interval (724a) of the G emission (724) for pixel line #1. The start time of the time interval (725a) of the B scan (725) for pixel line #1 may be performed before the end time of the G emission (724). For example, the start time of the time interval (725a) of the B scan (725) for pixel line #1 may be performed before the end time of the time interval (724b) of the G emission (724) for pixel line #n.The B emission (726) may be sequentially performed for the pixel lines within the pixel array (116) of the LCoS panel (115). For example, the time interval (726a) of the B emission (726) for pixel line #1 may start after the reference time (144) from the end time of the time interval (725a) of the B scan (725) for pixel line #1. The B emission (726) for pixel line #2 may be performed after the end time of the time interval (726a) of the B emission (726) for pixel line #1. Although not shown in FIG. 7B, another R scan may be performed before the end of the B emission (726). For example, the start time of the other R scan may be performed before the end time of the time interval (726b) of the B emission (726) for pixel line #n.

[0198] Referring to FIG. 7B, the length of the frame (729) according to the second example (430) may be shorter than the length of the frame (709) of the example (130) of FIG. 7A. Since the local dimming driving according to the second example (430) sequentially scans the second color for each pixel line while sequentially emitting light for each pixel line for the first color, the length of the frame (729) may be shorter than the length of the frame (709). Accordingly, the local dimming driving according to the second example (430) may have a higher driving frequency compared to the example (130) that does not use the local dimming driving. In the second example (430) of FIG. 7B, a case is illustrated where all pixel lines emit light, but the present disclosure is not limited thereto. For example, in the second example (430), only some pixel lines of the LCoS panel (115) may emit light. Accordingly, the local dimming drive according to the second example (430) can reduce power consumption compared to the example (130) that does not use local dimming drive.

[0199] Fig. 7c illustrates a frame (739) according to the third example (530) of Fig. 5b. In Fig. 7c, for convenience of explanation, it is assumed that the pixel array (116) (or pixels) of the LCoS panel (115) is implemented with n pixel lines (e.g., pixel line #1 to pixel line #n).

[0200] Referring to the third example (530) of FIG. 7c, within a frame (739), an R scan (731), an R emission (732), a G scan (733), a G emission (734), a B scan (735), and a B emission (736) may be performed. While the R scan (731) is sequentially performed for pixel lines, the R emission (732) may be sequentially performed for pixel lines within the pixel array (116) of the LCoS panel (115). For example, the time interval (732a) of the R emission (732) for pixel line #1 may start after a reference time (144) from the end time of the time interval (731a) of the R scan (731) for pixel line #1. The R emission (732) for pixel line #2 may be performed after the end time of the time interval (732a) of the R emission (732) for pixel line #1. The start time of the time interval (733a) of the G scan (733) for pixel line #1 can be performed before the end of the R emission (732). For example, the start time of the time interval (733a) of the G scan (733) for pixel line #1 can be performed after the end time of the time interval (732a) of the R emission (732) for pixel line #1. The G emission (734) can be sequentially performed for the pixel lines in the pixel array (116) of the LCoS panel (115). For example, the time interval (734a) of the G emission (734) for pixel line #1 can be started after the reference time (144) from the end time of the time interval (733a) of the G scan (733) for pixel line #1. The G emission (734) for pixel line #2 can be performed after the end time of the time interval (734a) of the G emission (734) for pixel line #1. The start time of the time interval (735a) of the B scan (735) for pixel line #1 can be performed before the end of the G emission (734) and after the end of the R scan (731).For example, the start time of the time interval (735a) of the B scan (735) for pixel line #1 may be performed before the end time of the G emission (734) for pixel line #n and after the end time of the R scan (731) for pixel line #n. The B emission (736) may be sequentially performed for the pixel lines in the pixel array (116) of the LCoS panel (115). For example, the time interval (736a) of the B emission (736) for pixel line #1 may be started after the reference time (144) from the end time of the time interval (735a) of the B scan (735) for pixel line #1. The B emission (736) for pixel line #2 may be performed after the end time of the time interval (736a) of the B emission (736) for pixel line #1.

[0201] Referring to FIG. 7C, the length of the frame (739) according to the third example (530) may be shorter than the length of the frame (729) according to the second example (430) of FIG. 7B. Since the local dimming driving according to the third example (530) performs sequential scanning for the second color per pixel line while performing sequential scanning for the first color per pixel line, the length of the frame (739) may be shorter than the length of the frame (729). Accordingly, the local dimming driving according to the third example (530) may have a higher driving frequency compared to the example (130) that does not use local dimming driving and the first and second examples (330) and (430) that use local dimming driving through one transistor. In the third example (530) of FIG. 7C, a case where all pixel lines emit light is illustrated, but the present disclosure is not limited thereto. For example, in the third example (530), only some of the pixel lines of the LCoS panel (115) may emit light. Accordingly, the local dimming driving according to the third example (530) can reduce power consumption compared to the example (130) that does not use local dimming driving.

[0202] Fig. 7d illustrates a frame (749) according to the fourth example (630) of Fig. 6b. In Fig. 7d, for convenience of explanation, it is assumed that the pixel array (116) (or pixels) of the LCoS panel (115) is implemented with n pixel lines (e.g., pixel line #1 to pixel line #n).

[0203] Referring to the fourth example (630) of FIG. 7d, within a frame (749), an R scan (741), an R emission (742), a G scan (743), a G emission (744), a B scan (745), and a B emission (746) may be performed. While the R scan (741) is sequentially performed for pixel lines, the R emission (742) may be sequentially performed for pixel lines within the pixel array (116) of the LCoS panel (115). For example, a time interval (742a) of the R emission (742) for pixel line #1 may start after a reference time (144) from the end time of the time interval (741a) of the R scan (741) for pixel line #1. The R emission (742) for pixel line #2 may be performed after the end time of the time interval (742a) of the R emission (742) for pixel line #1. The start time of the time interval (743a) of the G scan (743) for pixel line #1 can be performed before the end of the R emission (742). For example, the start time of the time interval (743a) of the G scan (743) for pixel line #1 can be performed after the end time of the time interval (742a) of the R emission (742) for pixel line #1. The G emission (744) can be sequentially performed for the pixel lines in the pixel array (116) of the LCoS panel (115). For example, the time interval (744a) of the G emission (744) for pixel line #1 can be started after the reference time (144) from the end time of the time interval (743a) of the G scan (743) for pixel line #1. The G emission (744) for pixel line #2 can be performed after the end time of the time interval (744a) of the G emission (744) for pixel line #1. The start time of the time interval (745a) of the B scan (745) for pixel line #1 can be performed before the end of the G emission (744) and before the end of the R scan (741).For example, the start time of the time interval (745a) of the B scan (745) for pixel line #1 may be performed after the end time of the time interval (744a) of the G emission (744) for pixel line #1. At this time, the end time of the time interval (744a) of the G emission (744) for pixel line #1 may be a time before the end time of the R scan (741). The B emission (746) may be sequentially performed for the pixel lines in the pixel array (116) of the LCoS panel (115). For example, the time interval (746a) of the B emission (746) for pixel line #1 may be started after the reference time (144) from the end time of the time interval (745a) of the B scan (745) for pixel line #1. The B emission (746) for pixel line #2 can be performed after the end time of the time interval (746a) of the B emission (746) for pixel line #1.

[0204] Referring to FIG. 7d, the length of the frame (749) according to the fourth example (630) may be shorter than the length of the frame (739) of the third example (530) of FIG. 7c. Since the local dimming driving according to the fourth example (630) sequentially scans the second color and the third color per pixel line while performing a sequential scan for the first color per pixel line, the length of the frame (749) may be shorter than the length of the frame (739). Accordingly, the local dimming driving according to the fourth example (630) may have a higher driving frequency compared to the example (130) that does not use local dimming driving, the first example (330) and the second example (430) that use local dimming driving through one transistor, and the third example (530) that uses local dimming driving through two transistors. In the fourth example (630) of FIG. 7d, a case is illustrated where all pixel lines emit light, but the present disclosure is not limited thereto. For example, in the fourth example (630), only some of the pixel lines of the LCoS panel (115) may emit light. Accordingly, the local dimming driving according to the fourth example (630) can reduce power consumption compared to the example (130) that does not utilize local dimming driving.

[0205] FIGS. 8A and 8B illustrate an example of a method for adjusting the response speed of a liquid crystal of an LCoS panel by applying reference data to a pixel before applying pixel data.

[0206] Fig. 8a illustrates examples (800, 810) of a method for adjusting the response speed of a liquid crystal of an LCoS panel (115) according to pixel data. Example (800) of Fig. 8a illustrates a case in which light is emitted after a reference time (e.g., reference time (144) of Fig. 1b) according to the response speed of the liquid crystal after pixel data is applied to each pixel of a pixel array (116) of an LCoS panel (115). Example (810) of Fig. 8a illustrates a case in which light is emitted after a reference time according to the adjusted response speed by applying pixel data after applying reference data to each pixel of a pixel array (116) of an LCoS panel (115).

[0207] Example (800) illustrates a first line (801) representing pixel data applied to a pixel, a second line (802) representing the transmittance (or response speed of the liquid crystal) of the LCoS panel (115), and a third line (803) representing light emitted from a light source (120). Referring to the first line (801), the display driver IC (113) can apply pixel data for displaying an image to the pixel within a time interval (801a). Referring to the second line (802), as the pixel data is applied within the time interval (801a), the transmittance of the liquid crystal of the LCoS panel (115) can gradually increase. For example, as the pixel data is applied within the time interval (801a), the transmittance of the LCoS panel (115) can gradually increase within the time interval (802a). Referring to the third line (803), when the transmittance of the liquid crystal is higher than the reference transmittance, the display driver IC (113) can control the light emitting circuit to emit light with respect to the pixel using the light emitting driver IC (117). For example, the light can be emitted within a time interval (803a). The start time of the time interval (803a) can correspond to the end time of the time interval (802a). For example, the time interval (802a) for the transmittance of the liquid crystal to change to be higher than the reference transmittance can be referred to as a reference time (e.g., the reference time (144) of FIG. 1B).

[0208] For example, in order to substantially adjust (or reduce) the above-described reference time, the display driver IC (113) may apply reference data before applying the pixel data for displaying an image. For more specific details, reference may be made to example (810).

[0209] Example (810) illustrates a first line (811) representing reference data and pixel data applied to a pixel, a second line (812) representing the transmittance (or response speed of the liquid crystal) of the LCoS panel (115), and a third line (813) representing light emitted from a light source (120). Referring to the first line (811), the display driver IC (113) can apply the reference data to the pixel within a time interval (811a). The display driver IC (113) can apply pixel data for displaying an image to the pixel to which the reference data has been applied within a time interval (811b) after the time interval (811a). Referring to the second line (812), as the reference data is applied within the time interval (811a), the transmittance of the liquid crystal of the LCoS panel (115) can gradually increase. For example, as the reference data is applied within the time interval (811a), the transmittance of the LCoS panel (115) may gradually increase within the time interval (812a). For example, as the pixel data is applied within the time interval (812a) after the time interval (811a), the transmittance of the LCoS panel (115) may gradually increase within the time interval (812a). As the reference data having a higher voltage than the pixel data is applied before the pixel data is applied, the length of the time interval (812a) until the transmittance of the liquid crystal changes to be equal to or greater than the reference transmittance may be shorter than the time interval (802a). Referring to the third line (813), when the transmittance of the liquid crystal is equal to or greater than the reference transmittance, the display driver IC (113) may control the light-emitting circuit to emit light with respect to the pixel using the light-emitting driver IC (117). For example, the light may be emitted within a time interval (813a). The start time of the time interval (813a) may correspond to the end time of the time interval (812a).For example, the time interval (812a) for the transmittance of the liquid crystal to change beyond the reference transmittance may be referred to as an adjusted reference time. In other words, by applying the reference data in advance before applying the pixel data, the adjusted reference time that is shorter than the reference time (e.g., the reference time (144) of FIG. 1B) may be used. The reference data may be referred to as a pre-charge voltage, a voltage for overdriving, or a liquid crystal driving voltage.

[0210] Referring to the first line (811) of FIG. 8A, the time interval (811a) at which the reference data is applied may be a time prior to the time interval (811b) at which the pixel data is applied. For example, the start time of the time interval (811a) may be a time prior to a specified time interval from the start time of the time interval (811b). For example, the specified time interval may include one or more horizontal synchronization times. For example, each of the horizontal synchronization times may be referred to as a time interval (or H interval) for emitting light from each of the pixel lines of the LCoS panel (115). However, the present disclosure is not limited thereto.

[0211] FIG. 8B illustrates an example (820) of a timing diagram showing a method of applying reference data before applying pixel data for displaying an image to a pixel, according to the first line (811) of FIG. 8A. For example, in order to apply the reference data to the pixel before applying the pixel data, the pixel may include a plurality of transistors. For example, the pixel may be included in the pixels of the LCoS panel (115) of the example (500) of FIG. 5A. In the example (820), for convenience of explanation, an example of a method of applying the reference data and the pixel data to the first pixel (301) and the fourth pixel (304) is illustrated.

[0212] Referring to data lines (313, 317) of example (820), the display driver IC (113) can apply reference data (e.g., HIGH). For example, the display driver IC (113) can apply the reference data using the first data line (313) related to the first pixel (301). For example, the display driver IC (113) can apply the reference data using the first data line (317) related to the fourth pixel (304). The display driver IC (113) can be in a state of continuously applying the reference data regardless of time. However, the present disclosure is not limited thereto. For example, referring to data lines (313, 317), the display driver IC (113) can apply the reference data within a time interval (841).

[0213] Referring to the scan line (312) of the example (820), the display driver IC (113) can apply the reference data to the pixel electrode (310) of the first pixel (301) by providing a scan signal to the gate electrode (311a) of the first transistor (311) of the first pixel (301) within a time interval (821) using the first data line (313). Thereafter, referring to the scan line (512) of the example (820), the display driver IC (113) can apply pixel data to the pixel electrode (310) of the first pixel (301) to which the reference data is applied by providing a scan signal to the gate electrode (511a) of the second transistor (511) of the first pixel (301) within a time interval (822). Referring to the second data line (513) of example (820), the pixel data applied to the pixel electrode (310) of the first pixel (301) to which the reference data is applied may be applied within a time interval (823) using the second data line (513). For example, the time interval (823) may be included within the time interval (822).

[0214] Referring to the scan line (322) of the example (820), the display driver IC (113) can apply the reference data to the pixel electrode (324) of the fourth pixel (304) by providing a scan signal to the gate electrode of the first transistor (325) of the fourth pixel (304) within a time interval (831) using the first data line (317). Thereafter, referring to the scan line (522) of the example (820), the display driver IC (113) can apply pixel data to the pixel electrode (324) of the fourth pixel (304) to which the reference data is applied by providing a scan signal to the gate electrode of the second transistor (525) of the fourth pixel (304) within a time interval (832). Referring to the second data line (517) of example (820), the pixel data applied to the pixel electrode (324) of the fourth pixel (304) to which the reference data is applied may be applied within a time interval (833) using the second data line (517). For example, the time interval (833) may be included within the time interval (832).

[0215] As described above, by using the reference data, the driving frequency (or refresh rate) of the display can be increased by reducing the response speed (or standby time). In addition, by applying the reference data in advance, the time required to emit light (or emission time) can be secured, and the light-emitting elements of the light-emitting circuit can be driven using a relatively low voltage. In the above example, a method of applying the reference data is described according to the structure of the pixels of the LCoS panel (115) illustrated in the example (500) of FIG. 5A, but the present disclosure is not limited thereto. For example, adjacent pixels among the pixels of the LCoS panel (115) can share a data line for applying the reference data. In other words, the reference data can be applied to the adjacent pixels using a single data line to which the adjacent pixels are electrically connected. For specific details related thereto, reference may be made to FIG. 8C below.

[0216] Figure 8c illustrates examples of pixels in an LCoS panel including data lines for applying reference data to adjacent pixels.

[0217] FIG. 8C illustrates an example (850) of pixels included in a pixel array (116) of an LCoS panel (115). In the example (850), four pixels included in the pixel array (116) are illustrated, but this is merely an example for convenience of explanation, and the present disclosure is not limited thereto. The pixel array (116) illustrated in the example (850) of FIG. 8C may include at least a portion of the pixel array (116) of the example (300) of FIG. 3A. For example, the first pixel (301) of the example (850) of FIG. 8C may correspond to the first pixel (301) included in the pixel array (116) of the example (300).

[0218] Referring to example (850), the pixel array (116) may include a first pixel (301), a second pixel (302), a third pixel (303), and a fourth pixel (304). For example, the first pixel (301) and the second pixel (302) may constitute a pixel line (300a). For example, the third pixel (303) and the fourth pixel (304) may constitute a pixel line (300b) following (or consecutive to) the pixel line (300a). In example (850), each of the pixel line (300a) and the pixel line (300b) is illustrated as including two pixels, but the present disclosure is not limited thereto. For example, each pixel line may include three or more pixels.

[0219] For example, the first pixel (301) may include a pixel electrode (310), a first transistor (311), and a second transistor (511). For example, the pixel electrode (310) may be formed of a metal for reflecting light provided from a light source (120). For example, the pixel electrode (310) may be formed of a metal plate or a metal thin film. For example, the first transistor (311) may include a gate electrode (311a) electrically connected to a second scan line (512) (e.g., Scan1-2), a first electrode (311b) electrically connected to a first data line (313) (e.g., Data1), and a second electrode (311c) electrically connected to the pixel electrode (310). For example, the first electrode (311b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode (311c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the second transistor (511) may include a gate electrode (511a) electrically connected to the first scan line (312) (e.g., Scan1-1), a third electrode (511b) electrically connected to the reference data line (855) (e.g., Data_Pre-charge), and a fourth electrode (511c) electrically connected to the pixel electrode (310). For example, the third electrode (511b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the fourth electrode (511c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0220] For example, the second transistor (511), the first scan line (312), and the reference data line (855) can be used to apply reference data to the pixel electrode (310) of the first pixel (301).

[0221] For example, the second pixel (302) may include a pixel electrode (314), a first transistor (315), and a second transistor (515). For example, the pixel electrode (314) may be formed of a metal for reflecting light provided from a light source (120). For example, the pixel electrode (314) may be formed of a metal plate or a metal thin film. For example, the first transistor (315) may include a gate electrode electrically connected to a first scan line (312) (e.g., Scan1-1), a first electrode electrically connected to a reference data line (855) (e.g., Data_Pre-charge), and a second electrode electrically connected to the pixel electrode (314). For example, the first electrode may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the second transistor (515) may include a gate electrode electrically connected to a second scan line (512) (e.g., Scan1-2), a third electrode electrically connected to a second data line (517) (e.g., Data2), and a fourth electrode electrically connected to a pixel electrode (314). For example, the third electrode may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the fourth electrode may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0222] For example, the first transistor (315), the first scan line (312), and the reference data line (855) can be used to apply reference data to the pixel electrode (314) of the second pixel (302).

[0223] For example, the third pixel (303) may include a pixel electrode (320), a first transistor (321), and a second transistor (511). For example, the pixel electrode (320) may be formed of metal for reflecting light provided from a light source (120). For example, the pixel electrode (320) may be formed of a metal plate or a metal thin film. For example, the first transistor (321) may include a gate electrode electrically connected to a first scan line (322) (e.g., Scan2), a first electrode electrically connected to a first data line (313) (e.g., Data1), and a second electrode electrically connected to the pixel electrode (320). For example, the first electrode may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the second transistor (511) may include a gate electrode (511a) electrically connected to a first scan line (312) (e.g., Scan1-1), a third electrode (511b) electrically connected to a reference data line (855) (e.g., Data_Pre-charge), and a fourth electrode (511c) electrically connected to a pixel electrode (320). For example, the third electrode (511b) may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the fourth electrode (511c) may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0224] For example, the second transistor (511), the first scan line (312), and the reference data line (855) can be used to apply reference data to the pixel electrode (320) of the third pixel (303).

[0225] For example, the fourth pixel (304) may include a pixel electrode (324), a first transistor (315), and a second transistor (525). For example, the pixel electrode (324) may be formed of a metal for reflecting light provided from a light source (120). For example, the pixel electrode (324) may be formed of a metal plate or a metal thin film. For example, the first transistor (315) may include a gate electrode electrically connected to a first scan line (312) (e.g., Scan1-1), a first electrode electrically connected to a reference data line (855) (e.g., Data_Pre-charge), and a second electrode electrically connected to the pixel electrode (324). For example, the first electrode may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the second electrode may be a source electrode or a drain electrode depending on the value of the applied data (or voltage). For example, the second transistor (525) may include a gate electrode electrically connected to the first scan line (322) (e.g., Scan2), a third electrode electrically connected to the second data line (517) (e.g., Data2), and a fourth electrode electrically connected to the pixel electrode (324). For example, the third electrode may be a drain electrode or a source electrode depending on the value of the applied data (or voltage), and the fourth electrode may be a source electrode or a drain electrode depending on the value of the applied data (or voltage).

[0226] For example, the first transistor (315), the first scan line (312), and the reference data line (855) can be used to apply reference data to the pixel electrode (324) of the fourth pixel (304).

[0227] Referring to the above, four pixels (301, 302, 303, 304) can be electrically connected to a reference data line (855). For example, the four pixels (301, 302, 303, 304) can share one reference data line (855). For example, reference data provided through the reference data line (855) can be applied to the four pixels (301, 302, 303, 304).

[0228] Figure 9 illustrates an example of dithering, which uses different pixels for each frame to represent an image in local dimming operation.

[0229] FIG. 9 illustrates an example (900) of a method for expressing an image using all pixels included in a pixel array (116) of an LCoS panel (115) and an example (950) of a method for expressing an image using some pixels according to dithering. For example, the dithering may be a method for adjusting some pixels used to display an image among all pixels in a pixel array (116) of an LCoS panel (115). For example, in order to adjust some pixels used to display the image, the display driver IC (113) may control the light-emitting circuit to emit light with respect to some pixels using the light-emitting driver IC (117). At this time, the display driver IC (113) may control the light-emitting circuit to refrain from emitting light with respect to the remaining pixels that are distinguished from the some pixels (or to emit black light) using the light-emitting driver IC (117). In Fig. 9, for convenience of explanation, it is assumed that the LCoS panel (115) includes six pixel lines.

[0230] Referring to example (900), the display driver IC (113) can use all pixels of the LCoS panel (115) to display an image within a specific frame. When all pixels of the LCoS panel (115) are used, all light-emitting elements in the light-emitting circuit of the light source (120) can emit light. As local dimming driving is used, the margin for the response speed of the liquid crystal may be insufficient. In other words, as the interval between the time at which light of the first color is emitted, the time at which light of the second color is emitted, and the time at which light of the third color is emitted becomes shorter as local dimming driving is used, color mixing between adjacent light-emitting elements may occur. To prevent the above-described color mixing, dithering of example (950) may be used.

[0231] Referring to example (950), the display driver IC (113) may use first pixels among all pixels of the LCoS panel (115) and second pixels that are distinct from a second frame following the first frame to display an image within a first frame. In one example, the first frame may represent odd frames, and the second frame may represent even frames.

[0232] In example (961), when using the first pixels of the LCoS panel (115), among all light-emitting elements in the light-emitting circuit of the light source (120), the first light-emitting elements corresponding to the first pixels can emit light. For example, the first light-emitting elements can include some pixels of pixel line #1, some pixels of pixel line #2 following pixel line #1, some pixels of pixel line #3 following pixel line #2, some pixels of pixel line #4 following pixel line #3, some pixels of pixel line #5 following pixel line #4, and some pixels of pixel line #6 following pixel line #5. In example (962), when using the second pixels of the LCoS panel (115), among all light-emitting elements in the light-emitting circuit of the light source (120), the second light-emitting elements corresponding to the second pixels can emit light. For example, the second light-emitting elements may include the remaining pixels of the pixel line #1, the remaining pixels of the pixel line #2, the remaining pixels of the pixel line #3, the remaining pixels of the pixel line #4, the remaining pixels of the pixel line #5, and the remaining pixels of the pixel line #6.

[0233] In example (963), when using the first pixels of the LCoS panel (115), the first light-emitting elements corresponding to the first pixels among all light-emitting elements in the light-emitting circuit of the light source (120) can emit light. For example, the first light-emitting elements can include pixels of the pixel line #1, pixels of the pixel line #3, and pixels of the pixel line #5. In example (964), when using the second pixels of the LCoS panel (115), the second light-emitting elements corresponding to the second pixels among all light-emitting elements in the light-emitting circuit of the light source (120) can emit light. For example, the second light-emitting elements can include pixels of the pixel line #2, pixels of the pixel line #4, and pixels of the pixel line #6.

[0234] Referring to the above, the display driver IC (113) can secure the above margin for preventing color mixing by emitting light with respect to pixels that are distinguished for each frame.

[0235] Referring to FIGS. 1A to 9, the present disclosure can increase the driving frequency of a display by utilizing local dimming driving. Furthermore, the present disclosure can reduce power consumption by utilizing local dimming driving. Furthermore, the present disclosure can prevent color mixing by driving pixels that emit light separately for each frame. As described above, by utilizing local dimming driving, the present disclosure can improve the usability of an electronic device (101) (e.g., an AR device or a VR device) including an LCoS panel (115) by increasing the usage time of the LCoS panel (115) and increasing the brightness.

[0236] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

[0237] FIG. 10 is a block diagram of an electronic device within a network environment according to various embodiments.

[0238] Referring to FIG. 10, in a network environment (1000), an electronic device (1001) may communicate with an electronic device (1002) via a first network (1098) (e.g., a short-range wireless communication network), or may communicate with at least one of an electronic device (1004) or a server (1008) via a second network (1099) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1001) may communicate with the electronic device (1004) via the server (1008). According to one embodiment, the electronic device (1001) may include a processor (1020), a memory (1030), an input module (1050), an audio output module (1055), a display module (1060), an audio module (1070), a sensor module (1076), an interface (1077), a connection terminal (1078), a haptic module (1079), a camera module (1080), a power management module (1088), a battery (1089), a communication module (1090), a subscriber identification module (1096), or an antenna module (1097). In some embodiments, the electronic device (1001) may omit at least one of these components (e.g., the connection terminal (1078)), or may have one or more other components added. In some embodiments, some of these components (e.g., sensor module (1076), camera module (1080), or antenna module (1097)) may be integrated into a single component (e.g., display module (1060)).

[0239] The processor (1020) may, for example, execute software (e.g., a program (1040)) to control at least one other component (e.g., a hardware or software component) of the electronic device (1001) connected to the processor (1020) and perform various data processing or operations. According to one embodiment, as at least a part of the data processing or operations, the processor (1020) may store commands or data received from other components (e.g., a sensor module (1076) or a communication module (1090)) in the volatile memory (1032), process the commands or data stored in the volatile memory (1032), and store result data in the non-volatile memory (1034). According to one embodiment, the processor (1020) may include a main processor (1021) (e.g., a central processing unit or an application processor) or a secondary processor (1023) (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor) that can operate independently or together with the main processor (1021). For example, when the electronic device (1001) includes the main processor (1021) and the secondary processor (1023), the secondary processor (1023) may be configured to use less power than the main processor (1021) or to be specialized for a given function. The secondary processor (1023) may be implemented separately from the main processor (1021) or as a part thereof.

[0240] The auxiliary processor (1023) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1060), the sensor module (1076), or the communication module (1090)) of the electronic device (1001), for example, on behalf of the main processor (1021) while the main processor (1021) is in an inactive (e.g., sleep) state, or together with the main processor (1021) while the main processor (1021) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1023) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1080) or a communication module (1090)). In one embodiment, the auxiliary processor (1023) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1001) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1008)). The learning algorithm can include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above. The artificial intelligence model can include multiple artificial neural network layers.The artificial neural network may be one of a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a bidirectional recurrent deep neural network (BRDNN), a deep Q-network, or a combination of two or more of the above, but is not limited to the examples described above. In addition to, or alternatively to, a hardware structure, an artificial intelligence model may include a software structure.

[0241] The memory (1030) can store various data used by at least one component (e.g., the processor (1020) or the sensor module (1076)) of the electronic device (1001). The data can include, for example, software (e.g., the program (1040)) and input data or output data for commands related thereto. The memory (1030) can include volatile memory (1032) or non-volatile memory (1034).

[0242] The program (1040) may be stored as software in memory (1030) and may include, for example, an operating system (1042), middleware (1044), or an application (1046).

[0243] The input module (1050) can receive commands or data to be used in a component of the electronic device (1001) (e.g., a processor (1020)) from an external source (e.g., a user) of the electronic device (1001). The input module (1050) can include, for example, a microphone, a mouse, a keyboard, a key (e.g., a button), or a digital pen (e.g., a stylus pen).

[0244] The audio output module (1055) can output audio signals to the outside of the electronic device (1001). The audio output module (1055) can include, for example, a speaker or a receiver. The speaker can be used for general purposes, such as multimedia playback or recording playback. The receiver can be used to receive incoming calls. In one embodiment, the receiver can be implemented separately from the speaker or as part of the speaker.

[0245] The display module (1060) can visually provide information to an external party (e.g., a user) of the electronic device (1001). The display module (1060) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (1060) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0246] The audio module (1070) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (1070) can acquire sound through the input module (1050), output sound through the sound output module (1055), or an external electronic device (e.g., electronic device (1002)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (1001).
