The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0044] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0049] FIG. 2 is a block diagram of a display module according to various embodiments.

[0050] Referring to FIG. 2, the display module (160) may include a display panel (210) and a display driver integrated circuit (DDI) (230) for controlling the display panel. Hereinafter, the DDI (230) may be referred to as a display driving circuit or a control circuit. The DDI (230) may include an interface module (231), a memory (233) (e.g., a buffer memory), an image processing module (235), or a mapping module (237). The DDI (230) may receive, for example, image information including image data or an image control signal corresponding to a command for controlling the image data, from another component of the electronic device (101) through the interface module (231). For example, image information may be received from a processor (120) (e.g., a main processor (121) (e.g., an application processor)) or an auxiliary processor (123) (e.g., a graphics processing unit) that operates independently of the function of the main processor (121). The DDI (230) may communicate with a touch circuit (250) or a sensor module (176) through the interface module (231). In addition, the DDI (230) may store at least some of the received image information in the memory (233), for example, in units of frames. The image processing module (235) may, for example, perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least some of the image data based on at least the characteristics of the image data or the characteristics of the display panel (210). The mapping module (237) may generate a voltage value or a current value corresponding to the image data that has been preprocessed or postprocessed through the image processing module (235).For example, the generation of voltage values ​​or current values ​​may be performed at least in part based on properties of pixels of the display panel (210) (e.g., arrangement of pixels (RGB stripe or pentile structure), or size of each sub-pixel). At least some pixels of the display panel (210) may be driven at least in part based on, for example, the voltage values ​​or current values, so that visual information (e.g., text, images, or icons) corresponding to the image data may be displayed through the display panel (210).

[0051] According to one embodiment, the display module (160) may further include a touch circuit (250). The touch circuit (250) may include a touch sensor (251) and a touch sensor IC (253) for controlling the same. The touch sensor IC (253) may control the touch sensor (251) to detect, for example, a touch input or a hovering input for a specific location of the display panel (210). For example, the touch sensor IC (253) may detect a touch input or a hovering input by measuring a change in a signal (e.g., voltage, light quantity, resistance, or charge quantity) for a specific location of the display panel (210). The touch sensor IC (253) may provide information (e.g., location, area, pressure, or time) regarding the detected touch input or hovering input to the processor (120). According to one embodiment, at least a portion of the touch circuit (250) (e.g., touch sensor IC (253)) may be included as part of the DDI (230), or as part of the display panel (210), or as part of another component (e.g., auxiliary processor (123)) disposed external to the display module (160).

[0052] According to one embodiment, the display module (160) may further include at least one sensor (e.g., a fingerprint sensor, an iris sensor, a pressure sensor, or an illuminance sensor) of the sensor module (176), or a sensor control circuit therefor. In this case, the at least one sensor or the sensor control circuit therefor may be embedded in a part of the display module (160) (e.g., the display panel (210) or the DDI (230)) or a part of the touch circuit (250). For example, when the sensor module (176) embedded in the display module (160) includes a biometric sensor (e.g., a fingerprint sensor), the biometric sensor may obtain biometric information (e.g., a fingerprint image) associated with a touch input through a part of the display panel (210). For example, when the sensor module (176) embedded in the display module (160) includes a pressure sensor, the pressure sensor may obtain pressure information associated with a touch input through a part or the entire area of ​​the display panel (210). According to one embodiment, the touch sensor (251) or sensor module (176) may be positioned between pixels of a pixel layer of the display panel (210), or above or below the pixel layer.

[0053] The DDI (230) and the display panel (210) included in the display module (160) of FIG. 2 may be implemented within a single component. For example, the display module (160) may include a plurality of layers. A specific layer among the plurality of layers may include components of the DDI (230), and another specific layer may include components of the display panel (210). Alternatively, the components of the DDI (230) and the components of the display panel (210) may be arranged across at least some of the plurality of layers. For example, the plurality of layers may include a driving layer. For example, the driving layer may be a layer that substantially includes components of the DDI (230). For example, the driving layer may include a silicon substrate. The silicon substrate may be referred to as a silicon backplane. The display module (160) using the silicon substrate can be driven at a relatively low voltage and at a high speed compared to a display module using a glass substrate. For example, the display module (160) using the silicon substrate can be used in wearable devices (e.g., AR devices and VR devices).

[0054] For example, the display module (160) including the silicon substrate may include a memory cell for each of a plurality of light-emitting elements. For example, the memory cell may store data to be emitted by the light-emitting element. For example, the memory cell may include a static random access memory (SRAM). The memory cell may be arranged in an area adjacent to the corresponding light-emitting element. For example, the adjacent area may be defined as a sub-pixel including the light-emitting element and the memory cell. As described above, the structure of the light-emitting element and the sub-pixel including the memory cell for the light-emitting element may be referred to as a MIP (memory in pixel) structure.

[0055] Hereinafter, the display may be referred to as including at least some components of the display module (160) of FIG. 2. For example, the display may be referred to as one component including a DDI (230) and a display panel (210). Examples of the display including a MIP are illustrated in FIGS. 3A and 3B below.

For example, the processor (310) may include at least a portion of the processor (120). For example, the display (320) may include at least a portion of the display module (160).

[0058] Referring to FIG. 3A, for example, the display (320) may include a plurality of layers (320-1, 320-2). For example, the plurality of layers (320-1, 320-2) may include a driving layer (320-1) and a light-emitting layer (320-2). For example, the driving layer (320-1) may represent a layer that performs control and processing to display an image by causing the light-emitting elements (331) of the light-emitting layer (320-2) to emit light. For example, the driving layer (320-1) may include a silicon substrate. For example, the light-emitting layer (320-2) may include a plurality of light-emitting elements (331). For example, the light-emitting layer (320-2) may be disposed on the driving layer (320-1).

[0059] For example, the display (320) may include an interface (315), an image processor (317), a latch (321), and a scan driver (323). For example, the interface (315), the image processor (317), the latch (321), and the scan driver (323) may be included in multiple layers (320-1, 320-2). For example, the interface (315), the image processor (317), the latch (321), and the scan driver (323) may be included in the driving layer (320-1). For example, the interface (315), the image processor (317), the latch (321), and the scan driver (323) may be arranged across the driving layer (320-1) and the light emitting layer (320-2). Additionally, for example, at least some of the interface (315), image processor (317), latch (321), and scan driver (323) may be included within the light emitting layer (320-2).

[0060] For example, the interface (315) may connect between the display (320) and the processor (310). For example, the interface (315) may include a MIPI (mobile industry processor interface) interface. For example, the processor (310) may provide an image and a control signal to the display (320) through the interface (315). For example, the image may represent information to be displayed externally through the light emission of the light emitting elements (331). For example, the control signal may include information for indicating a mode in which the display (320) is to be driven. For example, the interface (315) may include at least a part of the interface module (231) of FIG. 2.

[0061] For example, the image processor (317) may perform preprocessing or postprocessing (e.g., resolution, brightness, or size adjustment) on at least a portion of the image based on the characteristics of the image or the characteristics of the light-emitting layer (320-2) of the display (320). For example, the image processor (317) may generate a voltage value or a current value corresponding to the preprocessed or postprocessed image. For example, the generation of the voltage value or the current value may be performed based at least in part on the properties of the sub-pixels of the light-emitting layer (320-2) of the display (320) (e.g., the arrangement of pixels (RGB stripe or pentile structure), or the size of each sub-pixel). The properties may also be referred to as properties of the light-emitting elements included in the sub-pixels. The image processor (317) of FIG. 3A may include at least a portion of the image processing module (235) of FIG. 2. The image processor (317) of FIG. 3A may include at least a portion of the mapping module (237). Additionally, while FIG. 3A illustrates an example in which the image processor (317) performs the functions described above, the present disclosure is not limited thereto. For example, the display (320) may include other components that perform substantially the same functions as described above.

[0062] For example, the latch (321) can provide data (or image data) processed from the image processor (317) to a plurality of light-emitting elements (331) (or sub-pixels (330)) included in the display (320). For example, the latch (321) can latch or forward the data obtained from the image processor (317) to a plurality of light-emitting elements (331) (or sub-pixels (330)).

[0063] For example, the scan driver (323) may provide a scan signal for a plurality of scan lines. For example, each of the plurality of scan lines may be connected to a plurality of light-emitting elements. For example, the light-emitting layer (320-2) may include the plurality of light-emitting elements. For example, the plurality of light-emitting elements may be defined by a row indicating a first direction and a column indicating a second direction perpendicular to the first direction. For example, the second direction may indicate a direction in which the plurality of scan lines are arranged. For example, one scan line may be connected to light-emitting elements arranged on one row among the plurality of light-emitting elements. Hereinafter, the scan line may be referred to as one line.

[0064] For example, the display (320) may include a plurality of sub-pixels (330). For example, the sub-pixel (330) may include a light-emitting element (331), a circuit (333) for pulse width modulation (PWM), and a memory cell (335). For example, the light-emitting element (331) may be included in the light-emitting layer (320-2). For example, the light-emitting element (331) may be connected to the circuit (333). For example, the light-emitting element (331) may be connected to the memory cell (335) through the circuit (333).

[0065] For example, the circuit (333) for PWM may be placed in an area adjacent to the light-emitting element (331) defined by the sub-pixel (330). For example, the circuit (333) may be placed in an area of ​​the light-emitting layer (320-2) in which the light-emitting element (331) is placed. For example, the circuit (333) may be placed in an area of ​​the driving layer (320-1) corresponding to the light-emitting layer (320-2) in which the light-emitting element (331) is placed. Alternatively, the circuit (333) may be placed across the light-emitting layer (320-2) and the driving layer (320-1). The circuit (333) may extend from an area of ​​the light-emitting layer (320-2) and be included in an area of ​​the driving layer (320-1).

[0066] For example, the memory cell (335) may be disposed in an area of ​​the light-emitting layer (320-2) where the light-emitting element (331) is disposed. For example, the memory cell (335) may be disposed in an area of ​​the driving layer (320-1) corresponding to the light-emitting layer (320-2) where the light-emitting element (331) is disposed. Alternatively, the memory cell (335) may be disposed across the light-emitting layer (320-2) and the driving layer (320-1). The memory cell (335) may extend from an area of ​​the light-emitting layer (320-2) and be included in an area of ​​the driving layer (320-1).

[0067] For example, the light-emitting element (331) can emit light based on a signal obtained from the circuit (333). For example, the signal can include a pulse. For example, the light-emitting element (331) can include a light-emitting diode (LED). For example, the light-emitting element (331) can include a light-emitting diode whose color visible from the outside is red (R), blue (B), or green (G). For example, the signal can be used to control the time for which the light-emitting element (331) emits light according to the length (or width) of the pulse. For example, as the length of the pulse of the signal becomes longer, the time for which the light-emitting element (331) emits light becomes longer, and therefore, a brighter color can be displayed. In other words, the gradation (or gray level) of the color displayed by the light-emitting element (331) can be changed based on the width of the pulse. The method of generating the pulse based on a bit sequence may be referred to as a PWM technique. The length of the pulse may be identified based on data stored in a memory cell (335) for the light-emitting element (331).

[0068] Referring to the above, the display (320) of FIG. 3A may include at least a portion of the DDI (230) of FIG. 2 and the display panel (210). At least a portion of the DDI (230) may include an interface module (231), a memory (233), and an image processing module (235). For example, at least a portion of the interface module (231) may be included in the interface (315) of FIG. 3A. For example, at least a portion of the memory (233) may be included in the memory cell (335) of FIG. 3A. For example, at least a portion of the image processing module (235) may be included in the image processor (317). For example, FIG. 3A illustrates an example in which the image processor (317) is included in the display (320), but embodiments of the present disclosure are not limited thereto. For example, the image processor (317) may be located outside the display (320). If the image processor (317) is located outside the display (320), the display (320) may further include another interface for connecting the image processor (317) and the latch (321).

[0069] Referring to the above, the display (320) including the driving layer (320-1) including the silicon substrate can store data processed by logic operations in the memory cell (335) for the light-emitting element (331). For example, the data can include the bit sequence. For example, the bit sequence can be composed of 8 bits. For example, the length of the pulse can be identified based on the value of the bit of the bit sequence. Specific details related thereto are described below in FIG. 3B.

[0070] Figure 3b shows an example of one sub-pixel containing a MIP.

[0071] Fig. 3b illustrates an example of the structure of a sub-pixel (330) of Fig. 3a. Referring to Fig. 3b, the sub-pixel (330) may include a light-emitting element (331), a circuit for PWM (333), a memory cell (335), and a switch (337).

[0072] For example, the light-emitting element (331) may be connected to the circuit (333) via the switch (337). For example, the switch (337) may connect the circuit (333) and the light-emitting element (331) at a timing when the sub-pixel (330) (or the light-emitting element (331)) starts to emit light. For example, the timing may include a timing when a time period during which a line associated with the sub-pixel (330) (or the light-emitting element (331)) emits light begins. For example, the switch (337) may disconnect the connection between the circuit (333) and the light-emitting element (331) at a timing when the sub-pixel (330) (or the light-emitting element (331)) stops emitting light. For example, the timing may include a timing when a time period during which a line associated with the sub-pixel (330) (or the light-emitting element (331)) emits light ends (or expires). For example, the display (320) can control the connection status of the switch (337) for each line. For example, the display (320) can control the switch (337) using the path (337-1).

[0073] For example, the circuit (333) can generate a pulse based on data stored in the memory cell (335). For example, the circuit (333) can obtain the data from the memory cell (335) via a path (333-1). For example, the data can include an 8-bit bit sequence. For example, the memory cell (335) can store the 8-bit bit sequence. However, the embodiment of the present disclosure is not limited thereto, and a bit sequence having a different length can be stored in the memory cell (335). For example, the circuit (333) can perform the generation of the pulse based on a control signal obtained via a path (333-2).

[0074] For example, the width of the pulse may be determined based on the bit value of the bit sequence. For example, when the bit value is 1, a pulse may be generated for the bit having the value. For example, when the bit value is 0, a pulse may not be generated for the bit having the value. However, the embodiments of the present disclosure are not limited thereto, and when the bit value is 0, the pulse may be generated. For example, the width of the pulse according to the bit value of the bit sequence may be formed differently depending on the position of the bit within the bit sequence. For example, the closer to the least significant bit (LSB) of the bit sequence, the shorter the pulse width may be. For example, the closer to the most significant bit (MSB) of the bit sequence, the longer the pulse width may be. For example, the width (341) may represent the length of the pulse when the value of the MSB of the bit sequence is 1. For example, the width (342) may represent the length of the pulse when the value of the bit following the MSB of the bit sequence is 1. For example, the width (343) may represent the length of the pulse when the value of the LSB of the bit sequence is 1. However, the embodiment of the present disclosure is not limited thereto, and the closer it is to the LSB, the longer the width of the pulse may be. As described above, a technique for generating a pulse having a width according to the value of a bit in the bit sequence may be referred to as a PWM technique. In Fig. 3b, only the case where the value of one bit among the bits of the bit sequence is 1 is exemplified, but the embodiment of the present disclosure is not limited thereto. For example, the values ​​of a plurality of bits among the bits of the bit sequence may be 1. Or, the values ​​of all bits of the bit sequence may be 0.

[0075] To provide an enhanced user experience, an electronic device (101) is being developed that provides an augmented reality (AR) service that displays computer-generated information in conjunction with external objects in the real world. The augmented reality may be referred to as a virtual environment. For example, the electronic device (101) may include a wearable device that can be worn by a user. For example, the electronic device (101) may include user equipment, AR glasses, and / or a head-mounted device (HMD).

[0076] An electronic device (101) including an LED (e.g., μLED (micro-light emitting diode)) display for AR may be designed in the form of glasses. For example, the electronic device (101) may include an AR device in the form of glasses. The electronic device (101) transmits light emitted from a display (320), which is a light source, to a glass portion through a lens, thereby utilizing total reflection within the display (320) to transmit the light to the eyes of a user using the electronic device (101). The transmission of the light may indicate that an image is displayed through the display (320). At this time, the display (320) included in the electronic device (101) may include a light-emitting region with a relatively narrow area. In addition, the electronic device (101) in the form of glasses may have limitations in its mounting structure.

[0077] The electronic device (101), which is an AR device, may require a high PPI (pixel per inch) to provide a more immersive user experience. Accordingly, the display (320) of the electronic device (101) needs to support a high resolution within a light-emitting area having a small area of ​​the display (320). To this end, the electronic device (101) may use a sub-pixel rendering pixel structure (hereinafter, referred to as a sub-pixel rendering structure) that can provide a high resolution by using a small number of pixels (or sub-pixels). For example, the sub-pixels (330) included in the display (320) of the electronic device (101) may be implemented with a sub-pixel rendering structure. For example, the sub-pixel rendering structure may include an RGBG sub-pixel rendering structure.

[0078] In addition, the electronic device (101) in the form of glasses may require high output light emission because the energy transfer efficiency of the lens is low. In other words, although high output is required to provide smooth service of the electronic device (101), the capacity of the battery may be limited depending on the narrow mounting area of ​​the electronic device (101). To solve this problem, the electronic device (101) may use a mode for low power consumption. The low power consumption mode may indicate a state in which the electronic device (101) or the display (320) operates at low power. However, a method of simply converting RGBG data into RGB data in an RGBG sub-pixel rendering structure and driving it may cause a decrease in the screen brightness of the display (320) as the number of pixels (sub-pixels) used decreases.

[0079] Hereinafter, an electronic device and a method according to an embodiment of the present disclosure may utilize a low-power mode for driving some sub-pixels among all sub-pixels of a display (320) having an RGBG sub-pixel rendering structure. The electronic device and the method according to an embodiment of the present disclosure may reduce power consumption of a processor (310) (e.g., an application processor) by outputting an image with a lower resolution than the low-power mode and other modes. In addition, the electronic device and the method according to an embodiment of the present disclosure may reduce power consumption by reducing the number of emitting sub-pixels when utilizing the low-power mode. In addition, the electronic device and the method according to an embodiment of the present disclosure may compensate for a decrease in brightness that occurs when driving some sub-pixels by utilizing additional light emission.

[0080] Hereinafter, in the present disclosure, the other mode may indicate a state in which a power management integrated circuit (PMIC) (e.g., power management module (188)) of the electronic device (101) provides steady-state power. For example, the other mode may be referred to as a normal mode or an active mode. Hereinafter, in the present disclosure, for convenience of description, the other mode may be referred to as a first mode. For example, the mode for low power may be referred to as a second mode. The first mode and the second mode may be referred to as states of at least some of the electronic device (101), the processor (310), or the display (320).

[0081] Figures 4a to 4c illustrate examples of a method for controlling a light-emitting element of a display depending on a mode of an electronic device.

[0082] The modes of FIGS. 4A to 4C may include the first mode or the second mode. The electronic device may be understood to be substantially the same as the electronic device (101) of FIG. 1. For example, the display may include at least a portion of the display (320) of FIG. 3A. For example, the light-emitting element may be the light-emitting element (331) of the display (320).

[0083] Referring to FIG. 4A, examples (401, 402, 403, 404) of the display (320) controlling the light emission of light-emitting elements within the first mode of the electronic device (101) are illustrated. Examples (401, 402, 403, 404) may represent examples of light-emitting elements emitting light over time. Referring to examples (401, 402, 403, 404), the display (320) may include a plurality of light-emitting elements. For example, the plurality of light-emitting elements may be connected to a plurality of lines. For example, each of the lines may be referred to as a scan line. For example, the plurality of lines may include a first line (410), a second line (420), a third line (430), and a fourth line (440). For example, the first line (410) can be connected to eight light-emitting elements. For example, the first line (410) can be connected to the first light-emitting element (411), the second light-emitting element (412), the third light-emitting element (413), the fourth light-emitting element (414), and other light-emitting elements. The number of the plurality of lines, the number of the plurality of light-emitting elements, and the number of light-emitting elements connected to one line shown in FIG. 4A are merely exemplary, and the embodiments of the present disclosure are not limited thereto.

[0084] Referring to example (401), the display (320) can emit light from the light-emitting elements of the first line (410). For example, the display (320) can emit light from the first light-emitting element (411), the second light-emitting element (412), the third light-emitting element (413), the fourth light-emitting element (414) of the first line (410), and all of the other light-emitting elements. For example, the display (320) can emit light from the light-emitting elements of the first line (410) during a first time interval. For example, the display (320) can emit light from the light-emitting elements of the first line (410) during the first time interval from a first timing. The first timing can be triggered by a horizontal synchronization signal for the first line (410).

[0085] Referring to example (402), the display (320) can emit light from the light-emitting elements of the second line (420). For example, the display (320) can emit light from all of the light-emitting elements of the second line (420). For example, the display (320) can emit light from the light-emitting elements of the second line (420) during the first time interval. For example, the display (320) can emit light from the light-emitting elements of the second line (420) during the first time interval from the second timing. The second timing can be triggered by a horizontal synchronization signal for the second line (420). For example, a time interval between the second timing and the first timing can correspond to a period of the horizontal synchronization signal. Referring to examples (401) and (402), the light emitting elements of the first line (410) are illustrated as not emitting light while the light emitting elements of the second line (420) emit light. However, this is merely an example for convenience of explanation, and the embodiments of the present disclosure are not limited thereto. For example, examples (401, 402, 403, 404) are intended to indicate that each line emits light sequentially. In other words, examples (401, 402, 403, 404) may indicate that the timing at which each line emits light is different from each other. For example, as shown in FIG. 4c, while the first line (410) emits light, the second line (420) may also emit light together with the first line (410) from a timing that is a certain time after the first timing at which the first line (410) starts to emit light.

[0086] Referring to example (403), the display (320) can emit light from the light-emitting elements of the third line (430). For example, the display (320) can emit light from all of the light-emitting elements of the third line (430). For example, the display (320) can emit light from the light-emitting elements of the third line (430) during the first time period. For example, the display (320) can emit light from the light-emitting elements of the third line (430) during the first time period from the third timing.

[0087] Referring to example (404), the display (320) can emit light from the light-emitting elements of the fourth line (440). For example, the display (320) can emit light from all of the light-emitting elements of the fourth line (440). For example, the display (320) can emit light from the light-emitting elements of the fourth line (440) during the first time period. For example, the display (320) can emit light from the light-emitting elements of the fourth line (440) during the first time period from the fourth timing.

[0088] Referring to FIG. 4B, examples (451, 452, 453, 454) of the display (320) controlling the light emission of the light emitting elements within the second mode of the electronic device (101) are illustrated. Examples (451, 452, 453, 454) may represent examples of the light emitting elements emitting light over time. Referring to examples (451, 452, 453, 454), the display (320) may include a plurality of light emitting elements. For example, the plurality of light emitting elements may be connected to a plurality of lines. For example, the lines may be referred to as scan lines. For example, the plurality of lines may include a first line (410), a second line (420), a third line (430), and a fourth line (440). For example, the first line (410) may be connected to eight light emitting elements. For example, the first line (410) can be connected to the first light-emitting element (411), the second light-emitting element (412), the third light-emitting element (413), the fourth light-emitting element (414), and other light-emitting elements. The number of the plurality of lines, the number of the plurality of light-emitting elements, and the number of light-emitting elements connected to one line shown in FIG. 4B are merely exemplary, and the embodiments of the present disclosure are not limited thereto.

[0089] Referring to example (451), the display (320) can emit light from some of the light emitting elements of the first line (410). For example, the display (320) can emit light from the first light emitting element (411), the second light emitting element (412), the third light emitting element (413), and other light emitting elements (415) of the first line (410). In addition, within the second mode, the display (320) can refrain from emitting light from some of the light emitting elements of the first line (410) (or can delay, skip, or not emit light). For example, the display (320) can skip emitting light from the fourth light emitting element (414) and the light emitting element (416) of the first line (410). Compared to example (401), in order to reduce power consumption, in the second mode, the display (320) may not emit light from some of the light-emitting elements (414, 416) of the light-emitting elements of the first line (410). For example, the display (320) may emit light from the light-emitting elements (411, 412, 413, 415) of the first line (410) during a first time period. For example, the display (320) may emit light from the light-emitting elements (411, 412, 413, 415) of the first line (410) during the first time period from a first timing. The first timing may be triggered by a horizontal synchronization signal for the first line (410).

[0090] Referring to example (452), the display (320) can refrain from emitting light from the light-emitting elements of the second line (420). For example, the second line (420) can be a line that is continuous with the first line (410). For example, the display (320) can cause the light-emitting elements of the first line (410) to emit light again instead of causing the light-emitting elements of the second line (420) to emit light. For example, the display (320) can cause some of the light-emitting elements of the first line (410) to emit light again. For example, the display (320) can cause the first light-emitting element (411), the second light-emitting element (412), the third light-emitting element (413), and the other light-emitting elements (415) of the first line (410) to emit light again. For example, the display (320) can cause the light-emitting elements (411, 412, 413, 415) of the first line (410) to emit light during a second time interval that is different from the first time interval. For example, the second time interval can be shorter than the first time interval. For example, the display (320) can cause the light-emitting elements (411, 412, 413, 415) of the first line (410) to emit light during the second time interval that extends to the first time interval in which the light-emitting elements (411, 412, 413, 415) of the first line (410) emit light in example (451). For example, the timing at which the second time interval starts can be triggered from the timing at which the light emitting elements (411, 412, 413, 415) of the first line (410) in example (451) end emitting light in the first time interval.

[0091] Referring to example (453), the display (320) can emit light from some of the light-emitting elements of the third line (430). For example, the display (320) can emit light from the first light-emitting element (431), the second light-emitting element (432), the third light-emitting element (433), and other light-emitting elements (435) of the third line (430). In addition, within the second mode, the display (320) can refrain from emitting light from some of the light-emitting elements of the third line (430). For example, the display (320) can skip emitting light from the fourth light-emitting element (434) and the light-emitting element (436) of the third line (430). For example, the display (320) can cause the light-emitting elements (431, 432, 433, 435) of the third line (430) to emit light during the first time period. For example, the display (320) can cause the light-emitting elements (431, 432, 433, 435) of the third line (430) to emit light during the first time period from the third timing. The third timing can be triggered by a horizontal synchronization signal for the third line (430).

[0092] Referring to example (454), the display (320) can refrain from emitting light from the light-emitting elements of the fourth line (440). For example, the display (320) can re-emit light from the light-emitting elements of the third line (430) instead of emitting light from the light-emitting elements of the fourth line (440). For example, the display (320) can re-emit some of the light-emitting elements among the light-emitting elements of the third line (430). For example, the display (320) can re-emit light from the first light-emitting element (431), the second light-emitting element (432), the third light-emitting element (433), and the other light-emitting elements (435) of the third line (430). For example, the display (320) can re-emit light from the light-emitting elements (431, 432, 433, 435) of the third line (430) during the second time period. For example, the second time interval may be shorter than the first time interval. For example, the display (320) may cause the light-emitting elements (431, 432, 433, 435) of the third line (430) to emit light during the second time interval, which extends to the first time interval during which the light-emitting elements (431, 432, 433, 435) of the third line (430) emit light in example (453). For example, the timing at which the second time interval starts may be triggered from the timing at which the light-emitting elements (431, 432, 433, 435) of the third line (430) emit light in example (453) ends.

[0093] FIG. 4c illustrates an example (460) of a time interval during which the light-emitting elements emit light in the examples (401, 402, 403, 404) of FIG. 4a and an example (470) of a time interval during which the light-emitting elements emit light in the examples (451, 452, 453, 454) of FIG. 4b.

[0094] Referring to example (460), for example, the display (320) can sequentially emit light through a plurality of lines of the display (320). For example, the display (320) can sequentially emit light through all light-emitting elements of each of the plurality of lines. Each of the plurality of lines can emit light during a first time interval (465). For example, the display (320) can emit light through all light-emitting elements of the first line (410) during the first time interval (465) from the first timing (463-1). For example, the display (320) can emit light through all light-emitting elements of the second line (420) during the first time interval (465) from the second timing (463-2). For example, the time interval (463) between the second timing (463-2) and the first timing (463-1) can be a specified length. For example, the time interval (463) may correspond to the period of the horizontal synchronization signal.

[0095] Referring to example (470), for example, the display (320) can cause some light-emitting elements (e.g., light-emitting elements (411, 412, 413, 415)) of the light-emitting elements of the first line (410) to emit light during a first time period (465). For example, the display (320) can cause some light-emitting elements of the first line (410) to emit light during the first time period (465) from the first timing (463-1). For example, the display (320) can refrain from emitting light from the remaining light-emitting elements (e.g., light-emitting elements (414, 416)) that are different from some light-emitting elements of the first line (410). For example, the display (320) can refrain from emitting light from the light-emitting elements of the second line (420) and cause some light-emitting elements of the first line (410) to emit light again. For example, the display (320) can cause some of the light-emitting elements of the first line (410) to emit light again during a second time period (475). For example, the second time period (475) can extend from the first time period (465). For example, the second time period (475) can correspond to a time length (477) identified based on data of a memory cell for a light-emitting element of the second line (420). For example, the time length (477) can be identified according to a PWM technique using a bit sequence, which is the data stored in the memory cell for the light-emitting element of the second line (420). Also, for example, the first time period (465) can be identified according to a PWM technique using a bit sequence, which is data stored in the memory cell for the light-emitting element of the first line (410). For example, the display (320) may cause some of the light-emitting elements (e.g., light-emitting elements (431, 432, 433, 413)) of the light-emitting elements of the third line (430) to emit light during the first time period (465).For example, the display (320) can emit light from some of the light-emitting elements of the third line (430) during the first time period (465) from the third timing (463-3). For example, the display (320) can refrain from emitting light from the remaining light-emitting elements (e.g., light-emitting elements (434, 436)) that are different from some of the light-emitting elements among the light-emitting elements of the third line (430).

[0096] Referring to the above, the display (320) can cause some of the light-emitting elements of the first line (410) to emit light during the first time period (465) and the second time period (475). In other words, compared to the first mode, the display (320) can cause the light-emitting elements of the first line (410) to emit light for a longer period of time in the second mode.

[0097] Fig. 5a illustrates an example of a block diagram for illustrating a flow for displaying an image within the first mode. Fig. 5b illustrates an example of a method for converting image data within the first mode. Fig. 5c illustrates an example of the light-emitting states of light-emitting elements for displaying an image within the first mode.

[0098] The block diagram (500) of FIG. 5A may represent a flow of processing and displaying an image generated by the electronic device (101) of FIG. 3A within a first mode (515). Referring to the block diagram (500), the electronic device (101) may display an image (510) having a first resolution (e.g., 2560x2560) through the display (320).

[0099] For example, although the block diagram (500) of FIG. 5A illustrates an example in which the image processor (317) is included in the display (320), the embodiments of the present disclosure are not limited thereto. For example, the image processor (317) may be located outside the display (320). If the image processor (317) is located outside the display (320), the display (320) may further include another interface for connecting the image processor (317) and the latch.

[0100] For example, the processor (310) can identify whether to display the image (510) within the first mode (515) among the first mode (515) and the second mode (517) of the electronic device (101). In the above example, the first mode (515) of the electronic device (101) is described, but the embodiments of the present disclosure are not limited thereto. For example, the processor (310) can identify whether to display the image (510) within the first mode (515) of the processor (310) or the display (320). For example, when the processor (310) identifies that the image (510) is to be displayed within the first mode (515), the processor (310) can generate a signal to instruct the display (320) to the first mode (515). For example, if the processor (310) identifies that it will display an image (510) within the first mode (515), the display (320) may generate an image (510) having the first resolution that is implementable.

[0101] For example, the processor (310) can transmit a signal for indicating a first mode (515) and an image (510) having the first resolution to the display (320) through the transmission interface (315-1). For example, the display (320) can obtain the signal and the image (510) having the first resolution through the reception interface (315-2). For example, the reception interface (315-2) can represent an example of the interface (315) of FIG. 3A.

[0102] For example, the display (320) can be driven based on the first mode (515) indicated by the signal acquired through the receiving interface (315-2). For example, the display (320) can be identified to be driven in the first mode (515). The first mode (515) and the second mode (517) of FIG. 5A can be logical blocks for indicating the mode in which the electronic device (101) (or the processor (310), the display (320)) is driven.

[0103] For example, the display (320) can convert data of the image (510) having the first resolution. For example, the data may include RGB data. For example, the display (320) can convert the RGB data into RGBG data based on the image processor (317). For example, the display (320) can convert the 24-bit RGB data into 16-bit RG or BG data. For specific details related thereto, reference may be made to FIG. 5B.

[0104] Referring to FIG. 5B, the display (320) can convert RGB data (531, 532, 533, 534) forming an image (510) having the first resolution based on the implementation states of the plurality of light-emitting elements of the display (320). For example, the plurality of light-emitting elements can be implemented with an RGBG sub-pixel rendering structure. For example, the display (320) can convert RGB data (531, 532, 533, 534) into RGBG data (541, 542, 543, 544). For example, the display (320) can convert first RGB data (531) (e.g., R1, G1, B1) into first RG data (541) (e.g., R`1, G`1). For example, the display (320) can convert the second RGB data (532) (e.g., R2, G2, B2) into the first BG data (542) (e.g., B`1, G``1). For example, the display (320) can convert the third RGB data (533) (e.g., R3, G3, B3) into the second RG data (543) (e.g., R`2, G`2). For example, the display (320) can convert the fourth RGB data (534) (e.g., R4, G4, B4) into the second BG data (544) (e.g., B`2, G``2). As described above, the display (320) can convert RGB data composed of 24 bits into RG data or BG data composed of 16 bits.

[0105] Referring back to FIG. 5A, the display (320) can emit light through a plurality of light-emitting elements of the display (320) based on the converted data (520). The converted data (520) can include the RGBG data. The display (320) can display an image (510) by emitting light through the plurality of light-emitting elements of the display (320) based on the converted data (520). For specific details related thereto, reference may be made to FIG. 5C.

[0106] Referring to FIG. 5c, an image (510) having the first resolution (e.g., 2560x2560), an example (550) in which the plurality of light-emitting elements of the display (320) emit light based on converted data (520), and an actual image (570) displayed on the screen according to the emission are illustrated.

[0107] Referring to example (550), the display (320) may cause the plurality of light-emitting elements of the display (320) to emit light based on the converted data (520) to display the image (510) having the first resolution (e.g., 2560x2560). For example, the display (320) may cause all of the plurality of light-emitting elements included in the display (320) to emit light based on the converted data (520). As the plurality of light-emitting elements emit light as in example (550), an actual image (570) may be displayed on the screen of the display (320). For example, the actual image (570) may have the first resolution. Comparing the image (510) and the actual image (570), the image (510) may have the first resolution based on RGB data, and the actual image (570) may have the first resolution based on RGBG data. For example, the image (510) may have a resolution of 2560RGBx2560. For example, the actual image (570) may have a resolution of 2560RG / BGx2560.

[0108] Fig. 6a illustrates an example of a block diagram illustrating a flow for displaying an image within the second mode. Fig. 6b illustrates an example of a method for converting image data within the second mode. Fig. 6c illustrates an example of the light-emitting states of light-emitting elements for displaying an image within the second mode.

[0109] The block diagram (600) of FIG. 6A may represent a flow of processing and displaying an image generated by the electronic device (101) of FIG. 3A within a second mode (617). Referring to the block diagram (600), the electronic device (101) may display an image (610) having a second resolution (e.g., 1280x1280) through the display (320).

[0110] For example, although the block diagram (600) of FIG. 6A illustrates an example in which the image processor (317) is included in the display (320), the embodiments of the present disclosure are not limited thereto. For example, the image processor (317) may be located outside the display (320). If the image processor (317) is located outside the display (320), the display (320) may further include another interface for connecting the image processor (317) and the latch.

[0111] For example, the processor (310) can identify whether to display the image (610) within the second mode (617) among the first mode (615) and the second mode (617) of the electronic device (101). In the above example, the second mode (617) of the electronic device (101) is described, but the embodiments of the present disclosure are not limited thereto. For example, the processor (310) can identify whether to display the image (610) within the second mode (617) of the processor (310) or the display (320). For example, when the processor (310) identifies that the image (610) is to be displayed within the second mode (617), the processor (310) can generate a signal to instruct the display (320) to the second mode (617). For example, if the processor (310) identifies that it will display the image (610) within the second mode (617), the display (320) may generate the image (610) having the second resolution that is implementable.

[0112] For example, the processor (310) can transmit a signal for indicating a second mode (617) and an image (610) having the second resolution to the display (320) through the transmission interface (315-1). For example, the display (320) can obtain the signal and the image (610) having the second resolution through the reception interface (315-2). For example, the reception interface (315-2) can represent an example of the interface (315) of FIG. 3A.

[0113] For example, the display (320) can be driven based on the second mode (617) indicated by the signal acquired through the receiving interface (315-2). For example, the display (320) can be identified to be driven in the second mode (617). The first mode (615) and the second mode (617) of FIG. 6A can be logical blocks for indicating the modes in which the electronic device (101) (or the processor (310), the display (320)) operates.

[0114] For example, the display (320) can convert data of the image (610) having the second resolution. For example, the data may include RGB data. For example, the display (320) can convert the RGB data into RGB data and blank data based on the image processor (317). For example, the blank data may represent a specified bit sequence or a state in which data is not present (off). For example, when the bit sequence consists of 8 bits, the specified bit sequence may be '00000000'. For example, the display (320) can convert the 24-bit RGB data into 16-bit RG or B and blank data. For specific details related thereto, reference may be made to FIG. 6B.

[0115] Referring to FIG. 6B, the display (320) can convert RGB data (631, 632, 633, 634) forming an image (610) having the second resolution based on the implementation states of the plurality of light-emitting elements of the display (320). For example, the plurality of light-emitting elements can be implemented with an RGBG sub-pixel rendering structure. For example, the display (320) can convert RGB data (631, 632, 633, 634) into RGB data (641, 642, 643, 644). For example, the converted RGB data (641, 642, 643, 644) can include RG and BB (blue / blank) data. For example, the display (320) can convert the first RGB data (631) (e.g., R1, G1, B1) into the first RG data (641) (e.g., R`1, G`1). For example, the display (320) can convert the second RGB data (632) (e.g., R2, G2, B2) into the first BB data (642) (e.g., B`1, blank). For example, the display (320) can convert the third RGB data (633) (e.g., R3, G3, B3) into the second RG data (643) (e.g., R`2, G`2). For example, the display (320) can convert the fourth RGB data (634) (e.g., R4, G4, B4) into the second BB data (644) (e.g., B`2, blank). Referring to the above, the display (320) can convert RGB data consisting of 24 bits into RG or B and blank data consisting of 16 bits.

[0116] Referring back to FIG. 6A, the display (320) can identify a memory cell in which the converted data (620) is to be stored. For example, the display (320) can identify the memory cell for the light-emitting element to emit light based on the converted data (620) by using mapping information based on the image processor (317). The mapping information can define a mapping relationship between the data (620) converted from the image (610) having the second resolution and a plurality of light-emitting elements of the display (320). For example, the mapping information can include a look-up table (LUT).

[0117] For example, the display (320) can identify the light-emitting elements (601-1a) of the first line (601-1) that will emit the first RG data (641) based on the mapping information, and can store R data and G data in the memory cells of each of the light-emitting elements (601a, 601b). For example, the display (320) can identify the light-emitting elements (601c, 601d) of the first line (601-1) that will emit the first BB data (642) based on the mapping information, and can store B data and blank data in the memory cells of each of the light-emitting elements (601c, 601d). For example, the R, G, B, and blank data can include a bit sequence composed of 8 bits, which is the storage capacity of the memory cell. For example, the display (320) can identify the light-emitting elements (603a, 603b) of the third line (603-1) that will emit the second RG data (643) based on the mapping information, and can store R data and G data in the memory cells of each of the light-emitting elements (603a, 603b). For example, the display (320) can identify the light-emitting elements (603c, 603d) of the third line (603-1) that will emit the second BB data (644) based on the mapping information, and can store B data and blank data in the memory cells of each of the light-emitting elements (603c, 603d). For example, the R, G, B, and blank data can include a bit sequence composed of 8 bits, which is the storage capacity of the memory cell.

[0118] For example, the display (320) can identify data to be stored in a memory cell for a light-emitting element of a line that refrains from (or skips) emitting light based on the mapping information. In the example above, the display (320) can identify a first line (601-1) and a third line (603-1) that are connected to light-emitting elements for emitting light, and can identify a second line (602-1) that refrains from emitting light (or delays, skips, or does not emit light). For example, the display (320) can identify a light-emitting element (602a) of a second line (602-1) that is connected to a light-emitting element (601a) of the first line (601-1) based on the mapping information. For example, the display (320) can store data to be used for the light-emitting element (601a) of the first line (601-1) that additionally emits light (e.g., during the second time period) while the second line (602-1) refrain from emitting light, in the memory cell for the light-emitting element (602a). The data to be stored in the memory cell for the light-emitting element (602a) can be identified based on the mapping information. For example, the display (320) can identify data to be stored in the memory cell for the light-emitting element (602a) based on data (e.g., the first RG data (641)) stored in the memory cell for the light-emitting element (601a) while the first line (601-1) emits light (e.g., during the first time period). Specific details related thereto are described below with reference to FIGS. 8A to 9B.

[0119] Referring back to FIG. 6A, the display (320) may emit light from some of the plurality of light-emitting elements of the display (320) based on the converted data (620). The converted data (620) may include the RGB and blank data. The display (320) may display an image (610) by emitting light from some of the plurality of light-emitting elements of the display (320) based on the converted data (620). For specific details related thereto, reference may be made to FIG. 6C.

[0120] Referring to FIG. 6c, an image (610) having the second resolution (e.g., 1280x1280), an example (650) in which the plurality of light-emitting elements of the display (320) emit light based on converted data (620), and an actual image (670) displayed on the screen according to the emission are illustrated.

[0121] Referring to example (650), the display (320) may emit light from among the plurality of light-emitting elements of the display (320) based on the converted data (620) to display an image (610) having the second resolution (e.g., 1280x1280). For example, the display (320) may emit light from all of the plurality of light-emitting elements included in the display (320) based on the converted data (620). As the plurality of light-emitting elements emit light as in example (650), an actual image (670) may be displayed on the screen of the display (320). For example, the actual image (670) may have the second resolution. Comparing the image (610) and the actual image (670), the image (610) may have the second resolution based on RGB data, and the actual image (670) may substantially have the second resolution based on the RGB data (and blank data). For example, the image (610) may have a resolution of 1280x1280. For example, the actual image (670) may have a resolution of 1280x1280.

[0122] Referring to FIGS. 5C and 6C, among all light-emitting elements included in the display (320), some of the light-emitting elements emit light, and although the size of the screen seen from the outside is the same as the actual image (570) of FIG. 5C, the resolution of the actual image (670) may be different from the resolution of the actual image (570). For example, the actual image (570) of FIG. 5C may have a resolution of 2560x2560. In contrast, the actual image (670) of FIG. 6C may have a resolution of, for example, 1280x1280.

[0123] Although FIG. 6A illustrates an example in which the resolution of an image generated by the processor (310) is the second resolution by identifying the second mode, the embodiments of the present disclosure are not limited thereto. For example, the processor (310) may generate an image having a first resolution (e.g., 2560x2560) that is different from the second resolution. Accordingly, the display (320) may convert the resolution of the image from the first resolution to the second resolution. For example, the display (320) may scale down from the first resolution to the second resolution.

[0124] In FIG. 6A, an example is described in which lines (601-1, 603-1) configured in RGBG order from the left, which are lines related to light-emitting elements for displaying an image (610) (hereinafter, referred to as light-emitting lines), are identified, but the embodiment of the present disclosure is not limited thereto. For example, the display (320) can identify, based on the mapping information, a plurality of lines including a second line (602-2) configured in RGBG order from the right, which are lines related to light-emitting elements for displaying an image (610). Accordingly, the display (320) can identify, based on the mapping information, lines (601-2, 603-2) (hereinafter, referred to as non-emitting lines) related to light-emitting elements that do not display (or refrain from emitting) the image (610).

[0125] Although FIG. 6A illustrates an example of a display (320) in which one emissive line and one non-emissive line are implemented alternately, the present disclosure is not limited thereto. For example, the display (320) may alternatively implement two emissive lines and two non-emissive lines based on the mapping information.

[0126] FIG. 7A illustrates an exemplary circuit for a display driving multiple lines within a first mode. The display of FIG. 7A may represent an example of the display (320) of FIG. 3A.

[0127] Referring to FIG. 7A, the display (320) may include a plurality of sub-pixels (711, 712, 713, 714, 721, 722, 723, 724). The plurality of sub-pixels may be connected to specific lines. For example, the first sub-pixel (711), the second sub-pixel (712), the third sub-pixel (713), and the fourth sub-pixel (714) may be connected to the first line (710). For example, the fifth sub-pixel (721), the sixth sub-pixel (722), the seventh sub-pixel (723), and the eighth sub-pixel (724) may be connected to the second line (720).

[0128] For example, each of the sub-pixels may include a light-emitting element, a switch, a circuit for PWM, and a memory cell. For example, the first sub-pixel (711) may include a light-emitting element (711-1) for displaying a red (R) color, a switch (711-2), a circuit for PWM (711-3), and a memory cell (711-4).

[0129] For example, the light-emitting element (711-1) may be connected to the circuit (711-3) via the switch (711-2). For example, the switch (711-2) may connect the circuit (711-3) and the light-emitting element (711-1) at a timing when the first sub-pixel (711) (or the light-emitting element (711-1)) starts to emit light. For example, the timing may include a timing when a time period in which the first line (710) connected to the first sub-pixel (711) or the light-emitting element (711-1) emits light begins. For example, the switch (711-2) may disconnect the connection between the circuit (711-3) and the light-emitting element (711-1) at a timing when the first sub-pixel (711) or the light-emitting element (711-1) stops emitting light. For example, the timing may include the timing at which the time period during which the first line (710) connected to the first sub-pixel (711) or the light-emitting element (711-1) emits light ends (or expires). For example, the display (320) may control the connection status of the switch for each line. For example, the display (320) may control a plurality of switches within the first line (710). The plurality of switches may include the switch (711-2).

[0130] For example, the circuit (711-3) can generate a pulse based on data stored in the memory cell (711-4). For example, the circuit (711-3) can obtain the data from the memory cell (711-4). For example, the data may be an 8-bit bit sequence. For example, the memory cell (711-4) can store the 8-bit bit sequence. However, the embodiment of the present disclosure is not limited thereto, and a bit sequence having a different length may be stored in the memory cell (711-4). For example, the display (320) can control a plurality of circuits for each line based on a control signal. For example, the control signal may be a signal for driving the plurality of circuits in the first line (710) at a timing when the first line (710) is driven. For example, the circuit (711-3) can perform the generation of the pulse based on the control signal.

[0131] For example, the fifth sub-pixel (721) may include a light-emitting element (721-1) for displaying a blue (B) color, a switch (721-2), a circuit for PWM (721-3), a memory cell (721-4), and a line switch (721-5).

[0132] For example, the light-emitting element (721-1) may be connected to the circuit (721-3) via the switch (721-2). For example, the switch (721-2) may connect the circuit (721-3) and the light-emitting element (721-1) at a timing at which the fifth sub-pixel (721) (or the light-emitting element (721-1)) begins to emit light. For example, the timing may include a timing at which a time period at which the second line (720) connected to the fifth sub-pixel (721) or the light-emitting element (721-1) begins to emit light begins. For example, the second line (720) may be a line continuous to the first line (710). For example, the switch (721-2) can disconnect the connection between the circuit (721-3) and the light-emitting element (721-1) at the timing when the fifth sub-pixel (721) or the light-emitting element (721-1) stops emitting light. For example, the timing can include the timing when the time period in which the second line (720) connected to the fifth sub-pixel (721) or the light-emitting element (721-1) emits light ends (or expires). For example, the display (320) can control the connection state of the switch for each line. For example, the display (320) can control a plurality of switches within the second line (720). The plurality of switches can include the switch (721-2).

[0133] For example, the circuit (721-3) can generate a pulse based on data stored in the memory cell (721-4). For example, the circuit (721-3) can obtain the data from the memory cell (721-4). For example, the data can be an 8-bit bit sequence. For example, the memory cell (721-4) can store the 8-bit bit sequence. However, the embodiment of the present disclosure is not limited thereto, and a bit sequence having a different length can be stored in the memory cell (721-4). For example, the display (320) can control a plurality of circuits for each line based on a control signal. For example, the control signal can be a signal for driving the plurality of circuits in the second line (720) at a timing when the second line (720) is driven. For example, the circuit (721-3) can perform the generation of the pulse based on the control signal.

[0134] For example, the line switch (721-5) may be a switch for connecting between the first line (710) and the second line (720). For example, in the first mode, the line switch (721-5) may be in a state where the connection between the first line (710) and the second line (720) is disconnected.

[0135] Referring to FIG. 7A, the display (320) can sequentially emit light from light-emitting elements of a plurality of lines (710, 720, 730, 740). For example, the display (320) can emit light from light-emitting elements (711-1, 712-1, 713-1, 714-1) of a first line (710) during a first time period. For example, the display (320) can emit light from light-emitting elements (721-1, 722-1, 723-1, 724-1) of a second line (720) during the first time period. For example, the light-emitting elements (711-1, 712-1, 713-1, 714-1) of the first line (710) can emit light during the first time interval from the first timing. The light-emitting elements (721-1, 722-1, 723-1, 724-1) of the second line (720) can emit light during the first time interval from the second timing that has elapsed by a specified time interval from the first timing. For example, the specified time interval may correspond to the cycle of a horizontal synchronization signal that triggers driving of the lines. In addition, the display (320) can emit light from the light-emitting elements of the third line (730) and the light-emitting elements of the fourth line (740).

[0136] FIG. 7b illustrates an exemplary circuit for a display driving multiple lines in a second mode.

[0137] Referring to FIG. 7B, the display (320) may include a plurality of sub-pixels (711, 712, 713, 714, 721, 722, 723, 724). The plurality of sub-pixels may be connected to specific lines. For example, the first sub-pixel (711), the second sub-pixel (712), the third sub-pixel (713), and the fourth sub-pixel (714) may be connected to the first line (710). For example, the fifth sub-pixel (721), the sixth sub-pixel (722), the seventh sub-pixel (723), and the eighth sub-pixel (724) may be connected to the second line (720). The structure and connection state of the sub-pixels of FIG. 7B may be understood to be substantially the same as the structure and connection state of the sub-pixels of FIG. 7A. Therefore, overlapping contents are omitted in FIG. 7B below.

[0138] Referring to FIG. 7B, the display (320) can drive some lines among the plurality of lines (710, 720, 730, 740). For example, the display (320) can emit light from some light-emitting elements of the first line (710) and some light-emitting elements of the third line (730). For example, the display (320) can emit light from some light-emitting elements (711-1, 712-1, 713-1) among the light-emitting elements (711-1, 712-1, 713-1, 714-1) of the first line (710) during a first time period. For example, the display (320) may refrain from emitting light (or delay, skip, or not emit light) from the light-emitting element (714-1) of the fourth sub-pixel (714) during the first time period in which some light-emitting elements (711-1, 712-1, 713-1) of the first line (710) emit light.

[0139] Referring to FIG. 7B, the line switch (721-5) of the fifth sub-pixel (721) may be a switch for connecting the first line (710) and the second line (720). For example, in the second mode, the line switch (721-5) may be in a state of connecting the first line (710) and the second line (720). For example, the display (320) may control the line switches for each line using a control signal for changing the connection state of the line switch (721-5). For example, the display (320) may control the line switches of the second line (720) based on the control signal. For example, the display (320) may change the connection state of the line switch (721-5) from a state in which the first line (710) and the second line (720) are disconnected to a state in which they are connected before the timing at which the second line (720) starts to emit light based on the control signal. For example, the timing at which the second line (720) starts to emit light may be the timing at which the time length (477) of FIG. 4C starts. For example, the timing at which the second line (720) starts to emit light may coincide with the timing at which the emission of the first time period during which some of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710) emit light ends.

[0140] For example, the display (320) can refrain from emitting light from the light-emitting elements (721-1, 722-1, 723-1, 724-1) of the second line (720) and can use the second line (720) to emit light again from the first line (710). For example, the display (320) can identify some of the light-emitting elements (721-1, 722-1, 723-1, 724-1) of the second line (720). For example, the second line (720) can be a line that is continuous to the first line (710). For example, the display (320) can identify some light emitting elements (721-1, 722-1, 723-1) of the second line (720) connected to some light emitting elements (711-1, 712-1, 713-1) of the first line (710). The display (320) can use data stored in the memory cells of each of the some light emitting elements (721-1, 722-1, 723-1) of the second line (720) to cause some light emitting elements (711-1, 712-1, 713-1) of the first line (710) to emit light during a second time interval that is different from the first time interval. For example, the second time interval can be shorter than the first time interval. For example, the display (320) may cause some of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710) to emit light during the second time period, which extends to the first time period during which some of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710) emit light. For example, the timing at which the second time period begins may be triggered from the timing at which the emission of the first time period during which some of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710) emit light ends.

[0141] As described above, the display (320) can emit light from some of the light-emitting elements of the third line (730). In addition, the display (320) can refrain from emitting light from the light-emitting elements of the fourth line (740) that are continuous to the third line (730) and connected to the third line (730). The display (320) can emit light from some of the light-emitting elements of the third line (730) using the fourth line (740).

[0142] Figures 8a and 8b illustrate examples of a method for driving a plurality of lines having a first connection state within a second mode.

[0143] Referring to FIGS. 8A and 8B , the display (320) may include a plurality of sub-pixels (711, 712, 713, 714, 721, 722, 723, 724). The plurality of sub-pixels may be connected to specific lines. For example, the first sub-pixel (711), the second sub-pixel (712), the third sub-pixel (713), and the fourth sub-pixel (714) may be connected to the first line (710). For example, the fifth sub-pixel (721), the sixth sub-pixel (722), the seventh sub-pixel (723), and the eighth sub-pixel (724) may be connected to the second line (720). The structure and connection state of the sub-pixels of FIGS. 8A and 8B may be understood to be substantially the same as the structure and connection state of the sub-pixels of FIG. 7A . Therefore, overlapping contents are omitted in FIGS. 8a and 8b below.

[0144] The first connection state of FIGS. 8A and 8B may indicate a state in which sub-pixels located within the same column among the sub-pixels of consecutive lines (e.g., the first line (710) and the second line (720)) are connected. For example, the first sub-pixel (711) of the first line (710) and the fifth sub-pixel (721) of the second line (720) may be connected. For example, the second sub-pixel (712) of the first line (710) and the sixth sub-pixel (722) of the second line (720) may be connected. For example, the third sub-pixel (713) of the first line (710) and the seventh sub-pixel (723) of the second line (720) may be connected. For example, the fourth sub-pixel (714) of the first line (710) and the eighth sub-pixel (724) of the second line (720) may be connected. The column may be defined as a second direction perpendicular to the first direction in which the sub-pixels connected to one line are arranged. For example, the second direction may represent a direction in which a plurality of lines are arranged. For example, the direction in which the plurality of lines are arranged may represent a direction from the first line (710) to the fourth line (740). For example, the row may be defined as the first direction in which the sub-pixels connected to one line are arranged.

[0145] FIG. 8a illustrates an example of driving sub-pixels of the first line (710) within the second mode.

[0146] Referring to FIG. 8A, the display (320) can store data in the memory cells of each of the first sub-pixel (711), the second sub-pixel (712), the third sub-pixel (713), and the fourth sub-pixel (714) of the first line (710). For example, the display (320) can store a bit sequence in the memory cell (711-4) using the path (810). For example, the bit sequence can include 8 bits of data for emitting light with a red color by the light-emitting element (711-1). For example, the display (320) can store a bit sequence in the memory cell (712-4) using the path (820). For example, the bit sequence can include 8 bits of data for emitting light with a green color by the light-emitting element (712-1). For example, the display (320) can store a bit sequence in the memory cell (713-4) using the path (830). For example, the bit sequence can include 8 bits of data for emitting light of the light-emitting element (713-1) having a blue color. For example, the display (320) can store a bit sequence in the memory cell (714-4) using the path (840). For example, the bit sequence can include 8 bits of data for refraining from emitting light (or delaying, skipping, or not emitting light) of the light-emitting element (714-1) having a green color. For example, the bit sequence stored in the memory cell (714-4) can be a designated bit sequence. For example, the designated bit sequence can be '00000000'. Alternatively, the display (320) may not store data in the memory cell (714-4).

[0147] For example, the display (320) can generate a pulse according to the PWM technique using data stored in the memory cell. For example, the display (320) can control the operation of circuits for PWM of the first line (710). For example, the circuit (711-3) of the first sub-pixel (711) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (711-4). The pulse can represent a signal generated based on the bit sequence. The length (or width) of the pulse can be related to the time for which the light-emitting element (711-1) emits light. For example, the circuit (712-3) of the second sub-pixel (712) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (712-4). For example, the circuit (713-3) of the third sub-pixel (713) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (713-4). For example, the circuit (714-3) of the fourth sub-pixel (714) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (714-4). For example, the pulse generated by the circuit (714-3) can be a signal for not performing light emission of the light-emitting element.

[0148] For example, the display (320) can cause some light-emitting elements to emit light by controlling the switches of the line. For example, the display (320) can cause the light-emitting element (711-1) to emit light based on the pulse transmitted through the path (815) formed by controlling the switch (711-2) of the first sub-pixel (711). For example, the display (320) can cause the light-emitting element (712-1) to emit light based on the pulse transmitted through the path (825) formed by controlling the switch (712-2) of the second sub-pixel (712). For example, the display (320) can cause the light-emitting element (713-1) to emit light based on the pulse transmitted through the path (835) formed by controlling the switch (713-2) of the third sub-pixel (713). For example, the display (340) can refrain from emitting light from the light-emitting element (714-1) based on the pulse transmitted through the path (845) formed by controlling the switch (714-2) of the fourth sub-pixel (714). In FIG. 8A, an example is shown in which the path (845) is formed by the display (320) controlling the switch (714-2) based on a control signal, but the embodiments of the present disclosure are not limited thereto. For example, the display (320) can control the path not to be formed by using a switch associated with a light-emitting element that is not to emit light in the first line (710). For example, the display (320) can control the path (845) not to be formed by disconnecting the connection between the circuit (714-3) and the light-emitting element (714-1) through the switch (714-2).

[0149] FIG. 8B illustrates an example of driving sub-pixels of a second line (720) within the second mode. The example of FIG. 8B may represent an example of sub-pixels driven by the display after starting to drive the first line (710) in the example of FIG. 8A.

[0150] Referring to FIG. 8B, the display (320) can store data in the memory cells of each of the fifth sub-pixel (721), the sixth sub-pixel (722), the seventh sub-pixel (723), and the eighth sub-pixel (724) of the second line (720). For example, the display (320) can store a bit sequence in the memory cell (721-4) using the path (850). For example, the bit sequence can include 8 bits of data for emitting light from the light-emitting element (711-1) having a red color of the first line (710). For example, the display (320) can identify the bit sequence based on mapping information. For example, the display (320) can identify data associated with data stored in the memory cell (711-4) for emitting light of the light-emitting element (711-1) of the first line (710) based on the mapping information, and store the data in the memory cell (721-4). For example, the display (320) can store a bit sequence in the memory cell (722-4) using the path (860). For example, the bit sequence can include 8 bits of data for emitting light of the light-emitting element (712-1) having a green color of the first line (710). For example, the display (320) can store a bit sequence in the memory cell (723-4) using the path (870). For example, the bit sequence can include 8 bits of data for emitting light of the light-emitting element (713-1) having a blue color of the first line (710). For example, the display (320) can store a bit sequence in the memory cell (724-4) using the path (880). For example, the bit sequence can include 8 bits of data for refraining from emitting light of the light emitting element (714-1) having a green color of the first line (710). For example, the bit sequence stored in the memory cell (724-4) can be a designated bit sequence.For example, the specified bit sequence may be '00000000'. Alternatively, the display (320) may not store data in the memory cell (724-4).

[0151] For example, the display (320) can generate a pulse according to the PWM technique using data stored in the memory cell. For example, the display (320) can control the operation of circuits for PWM of the second line (720). For example, the circuit (721-3) of the fifth sub-pixel (721) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (721-4). The pulse can represent a signal generated based on the bit sequence. The length (or width) of the pulse can be related to the time for which the light-emitting element (711-1) of the first line (710) emits light. For example, the circuit (722-3) of the sixth sub-pixel (722) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (722-4). For example, the circuit (723-3) of the seventh sub-pixel (723) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (723-4). For example, the circuit (724-3) of the eighth sub-pixel (724) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (724-4).

[0152] For example, the display (320) can cause light-emitting elements to emit light by controlling line switches and switches. For example, the display (320) can cause the light-emitting element (711-1) to emit light based on the pulse transmitted through the path (855) formed by controlling the line switch (721-5) of the fifth sub-pixel (721) and the switch (711-2) of the first sub-pixel (711). For example, the display (320) can cause the light-emitting element (712-1) to emit light based on the pulse transmitted through the path (865) formed by controlling the line switch (722-5) of the sixth sub-pixel (722) and the switch (712-2) of the second sub-pixel (712). For example, the display (320) can cause the light-emitting element (713-1) to emit light based on the pulse transmitted through the path (875) formed by controlling the line switch (723-5) of the seventh sub-pixel (723) and the switch (713-2) of the third sub-pixel (713). For example, the display (340) can refrain from emitting light based on the pulse transmitted through the path (885) formed by controlling the line switch (724-5) of the eighth sub-pixel (724) and the switch (714-2) of the fourth sub-pixel (714). In FIG. 8B, an example is shown in which the path (885) is formed by the display (320) controlling the line switch (724-5) and the switch (714-2) based on a control signal, but the embodiments of the present disclosure are not limited thereto. For example, the display (320) can control so that a path is not formed by using a switch associated with a light-emitting element that does not emit light in the first line (710) or a line switch of the second line (720). For example, the display (320) can control so that a path (885) is not formed by disconnecting the connection between the circuit (724-3) of the eighth sub-pixel (724) and the light-emitting element (714-1) of the fourth sub-pixel (714) through the switch (714-2).Alternatively, the display (320) can be controlled so that the path (885) is not formed by disconnecting the connection between the eighth sub-pixel (724) and the fourth sub-pixel (714) via the line switch (724-5).

[0153] Referring to FIGS. 8A and 8B, the display (320) can, within the second mode, cause some of the light-emitting elements (711-1, 712-1, 713-1, 714-1) of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710) to emit light through memory stored in memory cells within the sub-pixels of the first line (710). Each of the light-emitting elements (711-1, 712-1, 713-1) can emit light during a first time period. For example, the first time period can be identified based on data stored in the memory cells for each of the light-emitting elements (711-1, 712-1, 713-1).

[0154] Additionally, the display (320) may, within the second mode, refrain from emitting light from the light-emitting elements of the second line (720). The display (320) may omit emitting light from the light-emitting elements of the second line (720) and may use the second line (720) to re-emit light from some of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710). For example, each of the light-emitting elements (711-1, 712-1, 713-1) may additionally emit light for a second time interval that is shorter than the first time interval. The second time interval may be identified based on data stored in a memory cell for each of the light-emitting elements (721-1, 722-1, 723-1) of the second line (720). For example, the second time interval may extend to the first time interval.

[0155] As described above, the display (320) can cause some light-emitting elements (711-1, 712-1, 713-1) of the first line (710) to emit light during the first time interval (e.g., the first time interval (465) of the example (470) of FIG. 4C) and the second time interval (e.g., the second time interval (475) of the example (470) of FIG. 4C). In other words, compared to the first mode, the display (320) can cause the light-emitting elements of the first line (710) to emit light for a longer period of time in the second mode.

[0156] Figures 9a and 9b illustrate examples of a method for driving a plurality of lines having a second connection state within a second mode.

[0157] Referring to FIGS. 9A and 9B , the display (320) may include a plurality of sub-pixels (711, 712, 713, 714, 721, 722, 723, 724). The plurality of sub-pixels may be connected to specific lines. For example, the first sub-pixel (711), the second sub-pixel (712), the third sub-pixel (713), and the fourth sub-pixel (714) may be connected to the first line (710). For example, the fifth sub-pixel (721), the sixth sub-pixel (722), the seventh sub-pixel (723), and the eighth sub-pixel (724) may be connected to the second line (720). The structure and connection state of the sub-pixels of FIGS. 9A and 9B may be understood to be substantially the same as the structure and connection state of the sub-pixels of FIG. 7A . Therefore, overlapping contents are omitted in FIGS. 9a and 9b below.

[0158] The second connection state of FIGS. 9A and 9B may indicate a state in which some of the sub-pixels of the continuous lines (e.g., the first line (710) and the second line (720)) are connected to sub-pixels located in different columns. For example, the first sub-pixel (711) of the first line (710) and the seventh sub-pixel (723) of the second line (720) may be connected. For example, the fourth sub-pixel (714) of the first line (710) and the eighth sub-pixel (724) of the second line (720) may be connected. In addition, the remaining sub-pixels of the sub-pixels of the continuous lines may be connected to sub-pixels located in the same column. For example, the second sub-pixel (712) of the first line (710) and the sixth sub-pixel (72) of the second line (720) may be connected. For example, the third sub-pixel (713) of the first line (710) and the fifth sub-pixel (721) of the second line (720) may be connected. The second connection state may indicate a connection state between light-emitting elements having the same emitting color.

[0159] FIG. 9a illustrates an example of driving sub-pixels of a first line (710) within the second mode.

[0160] Referring to FIG. 9A, the display (320) can store data in the memory cells of each of the first sub-pixel (711), the second sub-pixel (712), the third sub-pixel (713), and the fourth sub-pixel (714) of the first line (710). For example, the display (320) can store a bit sequence in the memory cell (711-4) using the path (910). For example, the bit sequence can include 8 bits of data for emitting light with a red color by the light-emitting element (711-1). For example, the display (320) can store a bit sequence in the memory cell (712-4) using the path (920). For example, the bit sequence can include 8 bits of data for emitting light with a green color by the light-emitting element (712-1). For example, the display (320) can store a bit sequence in the memory cell (713-4) using the path (930). For example, the bit sequence can include 8 bits of data for emitting light of the light-emitting element (713-1) having a blue color. For example, the display (320) can store a bit sequence in the memory cell (714-4) using the path (940). For example, the bit sequence can include 8 bits of data for refraining from emitting light (or delaying, skipping, or not emitting light) of the light-emitting element (714-1) having a green color. For example, the bit sequence stored in the memory cell (714-4) can be a designated bit sequence. For example, the designated bit sequence can be '00000000'. Alternatively, the display (320) may not store data in the memory cell (714-4).

[0161] For example, the display (320) can generate a pulse according to the PWM technique using data stored in the memory cell. For example, the display (320) can control the operation of circuits for PWM of the first line (710). For example, the circuit (711-3) of the first sub-pixel (711) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (711-4). The pulse can represent a signal generated based on the bit sequence. The length (or width) of the pulse can be related to the time for which the light-emitting element (711-1) emits light. For example, the circuit (712-3) of the second sub-pixel (712) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (712-4). For example, the circuit (713-3) of the third sub-pixel (713) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (713-4). For example, the circuit (714-3) of the fourth sub-pixel (714) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (714-4). For example, the pulse generated by the circuit (714-3) can be a signal for not performing light emission of the light-emitting element.

[0162] For example, the display (320) can cause some light-emitting elements to emit light by controlling the switches of the line. For example, the display (320) can cause the light-emitting element (711-1) to emit light based on the pulse transmitted through the path (915) formed by controlling the switch (711-2) of the first sub-pixel (711). For example, the display (320) can cause the light-emitting element (712-1) to emit light based on the pulse transmitted through the path (925) formed by controlling the switch (712-2) of the second sub-pixel (712). For example, the display (320) can cause the light-emitting element (713-1) to emit light based on the pulse transmitted through the path (935) formed by controlling the switch (713-2) of the third sub-pixel (713). For example, the display (340) can refrain from emitting light from the light-emitting element (714-1) based on the pulse transmitted through the path (945) formed by controlling the switch (714-2) of the fourth sub-pixel (714). In FIG. 9A, an example is shown in which the path (945) is formed by the display (320) controlling the switch (714-2) based on a control signal, but the embodiments of the present disclosure are not limited thereto. For example, the display (320) can control the path not to be formed by using a switch associated with a light-emitting element that is not to emit light in the first line (710). For example, the display (320) can control the path (945) not to be formed by disconnecting the connection between the circuit (714-3) and the light-emitting element (714-1) through the switch (714-2).

[0163] FIG. 9B illustrates an example of driving sub-pixels of a second line (720) within the second mode. The example of FIG. 9B may represent an example of sub-pixels driven by the display after starting to drive the first line (710) in the example of FIG. 9A.

[0164] Referring to FIG. 9B, the display (320) can store data in the memory cells of each of the fifth sub-pixel (721), the sixth sub-pixel (722), the seventh sub-pixel (723), and the eighth sub-pixel (724) of the second line (720). For example, the display (320) can store a bit sequence in the memory cell (721-4) using the path (950). For example, the bit sequence can include 8 bits of data for emitting light from the light-emitting element (713-1) having a blue color of the first line (710). For example, the display (320) can identify the bit sequence based on mapping information. For example, the display (320) can identify data associated with data stored in the memory cell (713-4) for emitting light of the light-emitting element (713-1) of the first line (710) based on the mapping information, and store the data in the memory cell (721-4). For example, the display (320) can store a bit sequence in the memory cell (722-4) using the path (960). For example, the bit sequence can include 8 bits of data for emitting light of the light-emitting element (712-1) having a green color of the first line (710). For example, the display (320) can store a bit sequence in the memory cell (723-4) using the path (970). For example, the bit sequence can include 8 bits of data for emitting light of the light-emitting element (711-1) having a red color of the first line (710). For example, the display (320) can store a bit sequence in the memory cell (724-4) using the path (980). For example, the bit sequence can include 8 bits of data for refraining from emitting light of the light emitting element (714-1) having a green color of the first line (710). For example, the bit sequence stored in the memory cell (724-4) can be a designated bit sequence.For example, the specified bit sequence may be '00000000'. Alternatively, the display (320) may not store data in the memory cell (724-4).

[0165] For example, the display (320) can generate a pulse according to the PWM technique using data stored in the memory cell. For example, the display (320) can control the operation of circuits for PWM of the second line (720). For example, the circuit (721-3) of the fifth sub-pixel (721) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (721-4). The pulse can represent a signal generated based on the bit sequence. The length (or width) of the pulse can be related to the time for which the light-emitting element (713-1) of the first line (710) emits light. For example, the circuit (722-3) of the sixth sub-pixel (722) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (722-4). For example, the circuit (723-3) of the seventh sub-pixel (723) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (723-4). For example, the circuit (724-3) of the eighth sub-pixel (724) can generate a pulse according to the PWM technique based on the bit sequence of the memory cell (724-4).

[0166] For example, the display (320) can cause light-emitting elements to emit light by controlling line switches and switches. For example, the display (320) can cause the light-emitting element (713-1) to emit light based on the pulse transmitted through the path (955) formed by controlling the line switch (721-5) of the fifth sub-pixel (721) and the switch (713-2) of the third sub-pixel (713). For example, the display (320) can cause the light-emitting element (712-1) to emit light based on the pulse transmitted through the path (965) formed by controlling the line switch (722-5) of the sixth sub-pixel (722) and the switch (712-2) of the second sub-pixel (712). For example, the display (320) can cause the light-emitting element (711-1) to emit light based on the pulse transmitted through the path (975) formed by controlling the line switch (723-5) of the seventh sub-pixel (723) and the switch (711-2) of the first sub-pixel (711). For example, the display (340) can refrain from emitting light based on the pulse transmitted through the path (985) formed by controlling the line switch (724-5) of the eighth sub-pixel (724) and the switch (714-2) of the fourth sub-pixel (714). In FIG. 9B, an example is shown in which the path (985) is formed by the display (320) controlling the line switch (724-5) and the switch (714-2) based on a control signal, but the embodiments of the present disclosure are not limited thereto. For example, the display (320) can control so that a path is not formed by using a switch associated with a light-emitting element that does not emit light in the first line (710) or a line switch of the second line (720). For example, the display (320) can control so that a path (985) is not formed by disconnecting the connection between the circuit (724-3) of the eighth sub-pixel (724) and the light-emitting element (714-1) of the fourth sub-pixel (714) through the switch (714-2).Alternatively, the display (320) can be controlled so that the path (985) is not formed by disconnecting the connection between the eighth sub-pixel (724) and the fourth sub-pixel (714) via the line switch (724-5).

[0167] Referring to FIGS. 8B and 9B, FIG. 8B illustrates the first connection state in which sub-pixels located in the same column are connected regardless of the color emitted by the light-emitting elements in consecutive lines. In contrast, FIG. 9B illustrates the second connection state in which sub-pixels having the same color emitted by the light-emitting elements in consecutive lines are connected. In the second connection state, a path may be formed in a twisted shape for connection between some sub-pixels (e.g., the first sub-pixel (711) and the seventh sub-pixel (723) in FIG. 9B).

[0168] Referring to FIGS. 9A and 9B, the display (320) can, within the second mode, cause some of the light-emitting elements (711-1, 712-1, 713-1, 714-1) of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710) to emit light through memory stored in memory cells within the sub-pixels of the first line (710). Each of the light-emitting elements (711-1, 712-1, 713-1) can emit light during a first time period. For example, the first time period can be identified based on data stored in the memory cells for each of the light-emitting elements (711-1, 712-1, 713-1).

[0169] Additionally, the display (320) may, within the second mode, refrain from emitting light from the light-emitting elements of the second line (720). The display (320) may omit emitting light from the light-emitting elements of the second line (720) and may use the second line (720) to re-emit light from some of the light-emitting elements (711-1, 712-1, 713-1) of the first line (710). For example, each of the light-emitting elements (711-1, 712-1, 713-1) may additionally emit light for a second time interval that is shorter than the first time interval. The second time interval may be identified based on data stored in a memory cell for each of the light-emitting elements (721-1, 722-1, 723-1) of the second line (720). For example, the second time interval may extend to the first time interval.

[0170] As described above, the display (320) can cause some light-emitting elements (711-1, 712-1, 713-1) of the first line (710) to emit light during the first time interval (e.g., the first time interval (465) of the example (470) of FIG. 4C) and the second time interval (e.g., the second time interval (475) of the example (470) of FIG. 4C). In other words, compared to the first mode, the display (320) can cause the light-emitting elements of the first line (710) to emit light for a longer period of time in the second mode.

[0171] Although examples of a display (320) in which one light-emitting line and one non-light-emitting line are implemented alternately in FIGS. 7A to 9B , the present disclosure is not limited thereto. For example, the display (320) may alternatively implement two light-emitting lines and two non-light-emitting lines based on the mapping information. Accordingly, the connection state between sub-pixels may be changed.

[0172] Figure 10 illustrates an example of an operational flow for a method of controlling a light-emitting element of a display.

[0173] At least one operation of the method of FIG. 10 may be performed by the electronic device (101) of FIG. 3A. For example, the electronic device (101) may include a wearable device. For example, the wearable device may include an AR device (e.g., AR glasses). For example, the method of FIG. 10 may be controlled by the display (320). For example, the display (320) may include at least a portion of the display module (160) of FIGS. 1 and 2. For example, the display (320) may include at least a portion of the DDI (230) of FIG. 2 and the display panel (210).

[0174] Referring to FIG. 10, in operation (1000), the display (320) may receive a signal indicating a first mode or a second mode. For example, the display (320) may receive the signal from the processor (310). For example, the signal may be generated by the processor (310) identifying a mode in which to display an image among the first mode and the second mode.

[0175] For example, the display (320) can obtain the image. For example, the display (320) can obtain the image to be displayed in the first mode or the second mode from the processor (310). For example, the image can have a resolution based on the mode identified by the processor (310). For example, if the processor (310) identifies the mode as the first mode, the image can have a first resolution (e.g., 2560x2560). For example, if the processor (310) identifies the mode as the second mode, the image can have a second resolution (e.g., 1280x1280) lower than the first resolution. However, the embodiments of the present disclosure are not limited thereto. For example, even if the processor (310) identifies the mode as the second mode, the image can have the first resolution. After this, the display (320) can perform processing to lower the first resolution of the image to the second resolution.

[0176] In operation (1010), the display (320) can identify whether the signal indicates the first mode. For example, the display (320) can identify whether the mode in which the image is to be displayed is the first mode based on the signal received from the processor (310). If the display (320) identifies that the mode is the first mode based on the signal in operation (1010), it can perform operation (1020). Alternatively, if the display (320) identifies that the mode is the second mode based on the signal, it can perform operation (1030).

[0177] In operation (1020), the display (320) can sequentially emit light through a plurality of lines, including a first line and a second line. Each of the plurality of lines can be referred to as a scan line. For example, the display (320) can sequentially emit light through the plurality of lines, including the first line and the second line continuous to the first line, within the first mode. For example, the display (320) can emit light through a plurality of light-emitting elements of each of the plurality of lines during a first time interval.

[0178] For example, the display (320) can cause the light-emitting elements of the first line to emit light during the first time interval. The light-emitting elements of the first line can represent all light-emitting elements connected to the first line. For example, the display (320) can store data in a memory cell for each of the light-emitting elements of the first line. For example, the data can include RGBG data identified based on the image. For example, the data can be configured as an 8-bit bit sequence according to the storage capacity of the memory cell. For example, the display (320) can generate a pulse according to a PWM technique using the data stored in the memory cell. For example, the display (320) can identify the first time interval in which the light-emitting elements will emit light based on the width of the generated pulse. For example, the display (320) can cause the light-emitting elements of the first line to emit light during the first time interval from a first timing. The first timing can be triggered by a horizontal synchronization signal for the first line.

[0179] For example, the display (320) can cause the light-emitting elements of the second line, which are continuous with the first line, to emit light during the first time period. The light-emitting elements of the second line can represent all light-emitting elements connected to the second line. For example, the display (320) can store data in a memory cell for each of the light-emitting elements of the second line. For example, the data can include RGBG data identified based on the image. For example, the data can be composed of an 8-bit bit sequence according to the storage capacity of the memory cell. For example, the display (320) can generate a pulse according to a PWM technique using the data stored in the memory cell. For example, the display (320) can identify the first time period in which the light-emitting elements are to emit light based on the width of the generated pulse. For example, the display (320) may cause the light-emitting elements of the second line to emit light during the first time interval from the second timing. The second timing may be triggered by a horizontal synchronization signal for the second line. For example, the time interval between the second timing and the first timing may correspond to the period of the horizontal synchronization signal.

[0180] In operation (1030), the display (320) may cause some of the light-emitting elements of the first line to emit light during the first time period. For example, the display (320) may cause some of the light-emitting elements of the first line to emit light during the first time period within the second mode. The display (320) may refrain from emitting light from the remaining light-emitting elements that are different from some of the light-emitting elements of the first line. For example, the display (320) may omit emitting light from the remaining light-emitting elements.

[0181] For example, the display (320) can identify some of the light-emitting elements for displaying the image based on mapping information. For example, the display (320) can identify memory cells of the some of the light-emitting elements based on the mapping information. The mapping information can define a mapping relationship between data converted from the image having the second resolution and a plurality of light-emitting elements of the display (320). For example, the mapping information can include a look-up table (LUT). For example, the display (320) can store data in a memory cell for each of the some of the light-emitting elements of the first line. For example, the data can include RGB data identified based on the image. The RGB data can include R data, G data, B data, and blank data. For example, the data can be composed of an 8-bit bit sequence according to the storage capacity of the memory cell.

[0182] For example, the display (320) can generate a pulse according to a PWM technique using data stored in a memory cell. For example, the display (320) can identify the first time interval in which the light-emitting element is to emit light based on the width of the generated pulse. For example, the display (320) can cause some of the light-emitting elements of the first line to emit light during the first time interval from a first timing. The first timing can be triggered by a horizontal synchronization signal for the first line. For example, the display (320) can identify the first time interval based on a first bit sequence stored in a first memory cell for the first light-emitting element, and cause the first light-emitting element to emit light during the first time interval. For example, the first light-emitting element can be included in some of the light-emitting elements of the first line.

[0183] In operation (1040), the display (320) may cause some of the light-emitting elements of the first line to emit light during a second time period using the second line. For example, the display (320) may additionally cause some of the light-emitting elements of the first line to emit light during the second time period using the second line within the second mode. The second time period may be extended to the first time period and may be shorter than the first time period. For example, the timing at which the second time period starts may be triggered from the timing at which the emission of the first time period in which some of the light-emitting elements of the first line emit light ends in operation (1030).

[0184] For example, the display (320) can identify, based on the mapping information, data to be stored in a memory cell for a light-emitting element of the second line that refrains from (or skips) emitting light. For example, the display (320) can identify the first line connected to the light-emitting element for emitting light, and can identify the second line that refrains from emitting light (or delays, skips, or does not emit light). The second line can represent a line that is continuous to and connected to the first line. For example, the display (320) can identify, based on the mapping information, a second light-emitting element of the second line that is connected to the first light-emitting element of the first line. For example, the display (320) can store, in a memory cell for the second light-emitting element, data to be used for the first light-emitting element of the first line that additionally emits light (e.g., during the second time period) while refraining from emitting light of the second line. Data to be stored in the second memory cell for the second light-emitting element can be identified based on the mapping information. For example, the display (320) can identify data to be stored in the second memory cell for the second light-emitting element based on data stored in the first memory cell for the first light-emitting element while the first line is emitting light (e.g., during the first time period). The data stored in the second memory cell can be referenced by a second bit sequence. For example, the display (320) can generate a pulse according to a PWM technique based on the data stored in the second memory cell for the second light-emitting element. For example, the width of the pulse generated based on the second bit sequence can correspond to the second time period.

[0185] For example, the display (320) can control a line switch for connecting the subpixels of the first line and the subpixels of the second line. For example, the display (320) can change the connection state of the first light-emitting element and the second light-emitting element from a disconnected state to a connected state by controlling the line switch. Accordingly, the display (320) can cause the first light-emitting element to emit light again during the second time period identified based on the second bit sequence stored in the second memory cell.

[0186] In Fig. 10, an example of a method for driving a display (320) including the first line and the second line is described, but the embodiments of the present disclosure are not limited thereto. For example, the display (320) may be substantially similarly applied to other lines (e.g., a third line and a fourth line) included in the plurality of lines. The third line may represent a line that is continuous to the second line. The fourth line may represent a line that is continuous to the third line and connected to the third line.

[0187] For example, the display (320) may cause some of the light-emitting elements of the third line, which is continuous with the second line, to emit light during the first time interval, as in operation (1030). For example, the display (320) may cause some of the light-emitting elements of the third line to additionally emit light during a third time interval, as in operation (1040), using the fourth line. The third time interval may extend to the first time interval during which some of the light-emitting elements of the third line emit light. For example, the third time interval may be identified based on the mapping information. For example, it may be the same as the second time interval. Alternatively, the third time interval may be different from the second time interval.

[0188] Referring to FIGS. 1 to 10, an electronic device and method according to an embodiment of the present disclosure can use a display (320) having an RGBG sub-pixel rendering structure in a low-power mode (e.g., the second mode) in which some of the sub-pixels among all sub-pixels are driven. Unlike a method of alternately scanning odd lines and even lines of a plurality of lines, the electronic device and method according to an embodiment of the present disclosure can scan some of the plurality of lines within the low-power mode. For example, within the low-power mode in which some of the sub-pixels are driven, the display (320) can scan some of the plurality of lines for all of the sub-pixels. Within the low-power mode, the display (320) may not scan other lines than some of the plurality of lines. The electronic device and method according to an embodiment of the present disclosure can reduce power consumption of a processor (310) (e.g., an application processor) by outputting an image with a lower resolution than a mode other than the low-power mode (e.g., the first mode). In addition, the electronic device and method according to an embodiment of the present disclosure can reduce power consumption by reducing the number of light-emitting sub-pixels when using the low-power mode. In addition, the electronic device and method according to an embodiment of the present disclosure can compensate for a decrease in brightness that occurs when some sub-pixels are driven by using additional light emission.

[0189] As described above, the wearable device (101) may include a display (320) including a driving layer (320-1) including a silicon substrate and an emitting layer (320-2) on the driving layer (320-1). The emitting layer (320-2) may include a plurality of emitting elements. The wearable device (101) may include a processor (310). The display (320) may be configured to receive a signal from the processor (310) indicating a first mode or a second mode for low power that is different from the first mode. The display (320) may be configured to sequentially emit a plurality of lines including a first line of the display (320) and a second line continuous to the first line within the first mode identified based on the signal. The light emitting elements included in each of the plurality of lines may emit light during a first time period. The display (320) may be configured to, within the second mode identified based on the signal, emit light among some of the light emitting elements of the first line during the first time period, and emit light among some of the light emitting elements of the first line during a second time period extending from the first time period in which the some of the light emitting elements of the first line emit light using the second line connected to the first line.

[0190] According to one embodiment, the display (320) may be configured, within the second mode, to emit light from a first light-emitting element among the light-emitting elements of the first line during the first time interval identified based on a first memory cell for the first light-emitting element. The display (320) may be configured, within the second mode, to emit light from the first light-emitting element during the second time interval identified based on a second memory cell for a second light-emitting element connected to the first light-emitting element among the light-emitting elements of the second line.

[0191] According to one embodiment, the display (320) may be configured to, in response to identifying the second mode based on the signal, store a first bit sequence indicating the first time interval in the first memory cell and store a second bit sequence indicating the second time interval in the second memory cell. The first time interval may be identified based on a pulse width modulation (PWM) scheme using the first bit sequence. The second time interval may be identified based on the PWM scheme using the second bit sequence.

[0192] According to one embodiment, the display (320) may be configured to change, within the second mode, switches of the second line from a first state that disconnects the first line and the second line, to a second state that connects the first line and the second line. A switch among the switches that connects the first light-emitting element and the second light-emitting element may form a path between the second memory cell and the first light-emitting element. The switch may be changed from the first state to the second state before the second time interval.

[0193] In one embodiment, the switch can be changed from the second state to the first state after the second time interval.

[0194] According to one embodiment, the path connects the first light-emitting element and the second light-emitting element, which are positioned in different columns, and when the color indicated by the first light-emitting element is red, the color indicated by the second light-emitting element may be red. The column may indicate a direction in which the plurality of lines are arranged.
