[0025] FIG. 22 is a block diagram of a display module according to various embodiments.

[0026] Figure 1 is a simplified block diagram of an exemplary electronic device.

[0027] Referring to FIG. 1, the electronic device (100) may be one of various types of mobile devices, such as a smartphone, a tablet, a wearable device, a cellular phone, and other similar computing devices. The components, their relationships, and their functions illustrated in FIG. 1 are merely exemplary and do not limit the implementations described or claimed in this document. The electronic device (100) may be referred to as a user device, a multi-function device, or a portable device. The electronic device (100) may include at least a portion of the electronic device (2101) of FIG. 21. The electronic device (100) may be a display module (or display) included in one of the devices exemplified above.

[0028] The electronic device (100) may include components including a display driving circuit (110) and a display panel (120). The above components are merely exemplary. For example, the electronic device (100) may include other components (e.g., a processor (e.g., at least a portion of the processor (2120) of FIG. 21).

[0029] The display driving circuit (110) may be used to display an image received from a processor of the electronic device (100) (e.g., processor (2120) of FIG. 21) (or a processor of an external electronic device) on the display panel (120). For example, the display driving circuit (110) may include at least a portion of the DDI (2230) of FIG. 22 or correspond to at least a portion of the DDI (2230).

[0030] The display panel (120) may be used to display an image based on the control of the display driving circuit (110). For example, the display panel (120) may include pixels for displaying the image. For example, each of the pixels may include sub-pixels. For example, the sub-pixels may be used to emit red light, green light, blue light, and / or white light. As a non-limiting example, the width of each of the sub-pixels may be in a range between about 50 micrometers and about 90 micrometers. For example, each of the sub-pixels may include a plurality of light emitting diodes (LEDs). As a non-limiting example, each of the plurality of LEDs may be a micro LED. Each of the sub-pixels may be exemplified in the description of FIG. 2.

[0031] Figure 2 illustrates a display panel of an exemplary electronic device.

[0032] Referring to FIG. 2, the display panel (120) may include pixels positioned along a plurality of horizontal lines. For example, the number of the plurality of horizontal lines may be N (a natural number greater than 1). For example, each of the pixels may include sub-pixels.

[0033] For example, a pixel (200-K) in the Kth horizontal line (K is a natural number greater than or equal to 1 and less than or equal to N) among the plurality of horizontal lines may include a sub-pixel (201-K) for emitting red light, a sub-pixel (202-K) for emitting green light, and a sub-pixel (203-K) for emitting blue light. Unlike the illustration in FIG. 2, some of the sub-pixels illustrated above may be excluded from the pixel (200-K). Unlike the illustration in FIG. 2, the pixel (200-K) may further include at least one sub-pixel. For example, the at least one sub-pixel may be used to emit red light, green light, blue light, or white light.

[0034] For example, a pixel (200-M) in the Mth horizontal line (M is a natural number greater than or equal to 1 and less than or equal to N and different from K) among the plurality of horizontal lines may include a sub-pixel (201-M) for emitting red light, a sub-pixel (202-M) for emitting green light, and a sub-pixel (203-M) for emitting blue light. Unlike the illustration in FIG. 2, some of the sub-pixels illustrated above may be excluded from the pixel (200-M). Unlike the illustration in FIG. 2, the pixel (200-M) may further include at least one sub-pixel. For example, the at least one sub-pixel may be used to emit red light, green light, blue light, or white light.

[0035] For example, each of the sub-pixels within each of the pixels within the display panel (120) may include two or more LEDs. For example, each of the two or more LEDs may be a micro LED. For example, each of the two or more LEDs may be referred to as a redundant LED. For example, the remaining LEDs excluding one of the two or more LEDs may be referred to as redundant LEDs.

[0036] For example, a sub-pixel (201-K) within a pixel (200-K) may include a plurality of LEDs (211-K), a sub-pixel (202-K) may include a plurality of LEDs (212-K), and a sub-pixel (203-K) may include a plurality of LEDs (213-K). As a non-limiting example, the number of the plurality of LEDs (211-K) may be different from the number of the plurality of LEDs (212-K). As a non-limiting example, the number of the plurality of LEDs (211-K) may be different from the number of the plurality of LEDs (213-K). As a non-limiting example, the number of the plurality of LEDs (212-K) may be different from the number of the plurality of LEDs (213-K).

[0037] For example, the number of each of the plurality of LEDs (211-K), the plurality of LEDs (212-K), and the plurality of LEDs (213-K) may be 2 to 3, unlike the illustration in FIG. 2. The number of each of the plurality of LEDs (211-K), the plurality of LEDs (212-K), and the plurality of LEDs (213-K) may be a natural number exceeding 4, unlike the illustration in FIG. 2.

[0038] For example, a sub-pixel (201-M) within a pixel (200-M) may include a plurality of LEDs (211-M), a sub-pixel (202-M) may include a plurality of LEDs (212-M), and a sub-pixel (203-M) may include a plurality of LEDs (213-M). As a non-limiting example, the number of the plurality of LEDs (211-M) may be different from the number of the plurality of LEDs (212-M). As a non-limiting example, the number of the plurality of LEDs (211-M) may be different from the number of the plurality of LEDs (213-M). As a non-limiting example, the number of the plurality of LEDs (212-M) may be different from the number of the plurality of LEDs (213-M).

[0039] For example, the number of each of the plurality of LEDs (211-M), the plurality of LEDs (212-M), and the plurality of LEDs (213-M) may be 2 to 3, unlike the illustration in FIG. 2. The number of each of the plurality of LEDs (211-M), the plurality of LEDs (212-M), and the plurality of LEDs (213-M) may be a natural number exceeding 4, unlike the illustration in FIG. 2.

[0040] For example, the number of the plurality of LEDs (211-K) may be different from the number of the plurality of LEDs (211-M), unlike the illustration in FIG. 2. For example, the number of the plurality of LEDs (212-K) may be different from the number of the plurality of LEDs (212-M), unlike the illustration in FIG. 2. For example, the number of the plurality of LEDs (213-K) may be different from the number of the plurality of LEDs (213-M), unlike the illustration in FIG. 2.

[0041] Referring again to FIG. 1, multiple LEDs included within a subpixel may emit light within different emission periods (emission cycles). For example, a single time period (e.g., 1 / 60 (second)) corresponding to a refresh rate (e.g., 60 Hz (hertz)) for displaying an image may include multiple emission periods. As a non-limiting example, the lengths of the multiple emission periods may be the same.

[0042] For example, a first LED among the plurality of LEDs may emit light within a first light-emitting period within the time period, and a second LED among the plurality of LEDs may emit light within a second light-emitting period within the time period. For example, the second light-emitting period may be subsequent to the first light-emitting period. For example, the first LED may start emitting light at a timing within the first light-emitting period according to a position of the subpixel, and the second LED may start emitting light at a timing within the second light-emitting period according to the position of the subpixel. For example, the first LED may start emitting light at the timing within the first light-emitting period according to a position of a horizontal line including the subpixel, and the second LED may start emitting light at the timing within the second light-emitting period according to a position of the horizontal line.

[0043] For example, the sub-pixel may include components for emitting the first LED within the first emission period and emitting the second LED within the second emission period. The components may be exemplified within the description of FIG. 3.

[0044] FIG. 3 illustrates subpixels within a display panel of an exemplary electronic device.

[0045] Referring to FIG. 3, a sub-pixel (300) may include a driving transistor (310), a first light-emitting control transistor (311), a second light-emitting control transistor (312), and a plurality of LEDs (320) including a first LED and a second LED. For example, the plurality of LEDs (320) may include a first LED (321) and a second LED (322).

[0046] For example, the driving transistor (310) may be used to provide current for emitting light to at least some of the plurality of LEDs (320). For example, the driving transistor (310) may include a first gate configured to obtain a data voltage (e.g., Vdata), a first source configured to obtain a driving voltage (e.g., VDD), and a first drain.

[0047] For example, the first light-emitting control transistor (311) may include a second gate, a second source connected to the first drain, and a second drain connected to the anode of the first LED (321) among the plurality of LEDs (320). For example, the second light-emitting control transistor (312) may include a third gate, a third source connected to the first drain, and a third drain connected to the anode of the second LED (322) among the plurality of LEDs (320).

[0048] For example, among the plurality of LEDs (320), a first LED (321) may emit light within the first emission section based on a current provided through the driving transistor (310) according to the data voltage and a first emission signal (331) provided to the second gate, and a second LED (322) among the plurality of LEDs (320) may emit light within the second emission section based on the current and a second emission signal (332) provided to the third gate. The emission of the first LED (321) within the first emission section and the emission of the second LED (322) within the second emission section may be exemplified within the descriptions of FIGS. 3 and 4.

[0049] Figure 4 illustrates an exemplary method for controlling sub-pixels within a display panel.

[0050] Referring to FIG. 4, a time section (400) corresponding to a reproduction rate may include a plurality of light emission sections. For example, the time section (400) may include a first light emission section (401), a second light emission section (402) following the first light emission section (401), a third light emission section (403) following the second light emission section (402), and a fourth light emission section (404) following the third light emission section (403).

[0051] FIG. 4 illustrates an example in which the second light emission period (402) is immediately following the first light emission period (401), but the time period (400) may further include a light emission period between the first light emission period (401) and the second light emission period (402).

[0052] Referring further to FIG. 3, the display driving circuit (110) can provide the first gate with a data voltage for displaying an image within a time interval (400).

[0053] For example, the display driving circuit (110) may provide a first light emitting signal (331) to the second gate in order to provide current according to the data voltage to the first LED (321) among the plurality of LEDs (320) using the driving transistor (310) within the first light emitting period (401) within the time period (400). For example, the first LED (321) among the plurality of LEDs (320) may, in response to the first light emitting signal (331), emit light with a luminance (L) corresponding to the current for displaying the image. Emitting light from the first LED (321) within the first light emitting period (401) to provide luminance (L) may be more efficient than simultaneously emitting light from both the first LED (321) and the second LED (322) within the first light emitting period (401) to provide luminance (L) due to the respective characteristics of the first LED (321) and the second LED (322). The above characteristics of each of the first LED (321) and the second LED (322) can be exemplified within the description of FIG. 5.

[0054] Figure 5 is a chart showing the relationship between the current provided to the LED and the efficiency of the LED.

[0055] Referring to FIG. 5, the horizontal axis of the chart (500) represents the current provided to the LED (e.g., the first LED (321) or the second LED (322)), the vertical axis of the chart (500) represents the efficiency of the LED (unit: cd / A), and the line (510) within the chart (500) represents the relationship between the current and the efficiency.

[0056] For example, as represented by line (510), when the current provided to the LED is Ia, the efficiency (or luminous efficiency) of the LED is Y, and when the current provided to the LED is Ib, which is higher than Ia, the efficiency of the LED may be K, which is higher than Y. For example, the LED may have a higher efficiency when it obtains a higher current.

[0057] Referring again to FIG. 4, the current provided to the first LED (321) among the first LED (321) and the second LED (322) in order to provide luminance (L) using the first LED (321) among the first LED (321) and the second LED (322) within the first light-emitting section (401) may be higher than the current provided to each of the first LED (321) and the second LED (322) in order to provide luminance (L) using both the first LED (321) and the second LED (322) within the first light-emitting section (401). Since each of the first LED (321) and the second LED (322) has a higher efficiency (e.g., luminous efficiency or current efficiency) when obtaining a higher current, emitting only the first LED (321) within the first light-emitting section (401) to provide luminance (L) may be more efficient than emitting both the first LED (321) and the second LED (322) within the first light-emitting section (401) to provide luminance (L). For example, the electronic device (100) may display an image with enhanced efficiency by emitting one of the plurality of LEDs (320) within the sub-pixel (300) based on a higher current.

[0058] For example, the display driving circuit (110) may provide a second light emitting signal (332) to the third gate to provide the current to the second LED (322) among the plurality of LEDs (320) using the driving transistor (310) within the second light emitting period (402) within the time period (400). For example, the second LED (322) among the plurality of LEDs (320) may emit light with a luminance (L) in response to the second light emitting signal (332). Emitting only the second LED (322) within the second light emitting period (402) to provide the luminance (L) may be more efficient than emitting both the first LED (321) and the second LED (322) within the second light emitting period (402) to provide the luminance (L). For example, the electronic device (100) can display an image with enhanced efficiency by emitting one of the plurality of LEDs (320) within a sub-pixel (300) based on a higher current.

[0059] For example, the display driving circuit (110) may provide a first light emitting signal (331) to the second gate in order to provide the current to the first LED (321) among the plurality of LEDs (320) using the driving transistor (310) within the third light emitting period (403) within the time period (400). For example, the first LED (321) among the plurality of LEDs (320) may emit light with a luminance (L) in response to the first light emitting signal (331).

[0060] For example, the display driving circuit (110) may provide a second light emitting signal (332) to the third gate in order to provide the current to the second LED (322) among the plurality of LEDs (320) using the driving transistor (310) within the fourth light emitting period (404) within the time period (400). For example, the second LED (321) among the plurality of LEDs (320) may emit light at a brightness (L) in response to the second light emitting signal (332).

[0061] Although FIG. 4 illustrates an example in which the first LED (321) emits light within the first light-emitting section (401) and the third light-emitting section (403), and the second LED (322) emits light within the second light-emitting section (402) and the fourth light-emitting section (404), the display driving circuit (110) may provide the first light-emitting signal (321) and the second light-emitting signal (322) so that the first LED (321) emits light within the first light-emitting section (401) and the second light-emitting section (402), and the second LED (322) emits light within the third light-emitting section (403) and the fourth light-emitting section (404).

[0062] Referring back to FIG. 3, the plurality of LEDs (320) within the sub-pixel (300) may further include a third LED (323). For example, the third LED (323) among the plurality of LEDs (320) may or may not have a manufacturing defect. As a non-limiting example, the fact that the third LED (323) has a manufacturing defect may indicate that the third LED (323) is shorted. As a non-limiting example, the fact that the third LED (323) has a manufacturing defect may indicate that the third LED (323) is open-circuited or opened. As a non-limiting example, the fact that the third LED (323) has a manufacturing defect may indicate that the third LED (323) is misaligned or aligned incorrectly.

[0063] For example, the sub-pixel (300) may further include a third light-emitting control transistor (313). The third light-emitting control transistor (313) may include a fourth gate, a fourth source connected to the first drain, and a fourth drain connected to the anode of a third LED (323) among the plurality of LEDs (320). For example, the third LED (323) among the plurality of LEDs (320) may or may not light up in a third light-emitting period following the second light-emitting period based on the current provided through the driving transistor (310) according to the data voltage and the third light-emitting signal (333) provided to the fourth gate, depending on whether there is a manufacturing defect. For example, the control of the sub-pixel (300) may vary depending on whether the third LED (323) has a manufacturing defect. The control may be exemplified in the descriptions of FIGS. 3 and 6.

[0064] FIG. 6 illustrates an exemplary method for controlling a sub-pixel containing an LED having a manufacturing defect.

[0065] Referring further to FIG. 6, the display driving circuit (110) may provide a third light emission signal (333) to the fourth gate to provide the current according to the data voltage to the third LED (323) among the plurality of LEDs (320) using the driving transistor (310) within the third light emission period (403) within the time period (400) when the third LED (323) does not have a manufacturing defect, as indicated by the state (600). For example, the third LED (323) among the plurality of LEDs (320) may, in response to the third light emission signal (333), emit light with a brightness (L) corresponding to the current for displaying the image.

[0066] For example, the display driver circuit (110) may refrain from or bypass providing the third light emission signal (333) to the fourth gate within the third light emission period (403) when the third LED (323) has a manufacturing defect, as indicated by state (650). For example, the display driver circuit (110) may refrain from emitting light within the third light emission period (403) by refraining from providing the third light emission signal (333).

[0067] As a non-limiting example, assume a sub-pixel (300) that includes only a single light-emitting control transistor each connected (in parallel) to a plurality of LEDs (320), and assume that a third LED (323) among the plurality of LEDs (320) is short-circuited. The current provided through the driving transistor (310) within such a sub-pixel (300) may be provided only to the short-circuited third LED (323). For example, the sub-pixel (300) may be dead due to the short-circuited third LED (323), because the current is not provided to the remaining LEDs that do not have a manufacturing defect (e.g., the first LED (321) and the second LED (322).

[0068] For example, unlike the above assumption, since the sub-pixel (300) includes a plurality of light-emitting control circuits (e.g., a first light-emitting control circuit (321), a second light-emitting control circuit (322), and a third light-emitting control circuit (323)) each connected to a plurality of LEDs (320) (e.g., a first LED (321), a second LED (322), and a third LED (323)), the sub-pixel (300) can provide light using other parts of the plurality of LEDs (320) even if some of the plurality of LEDs (320) are short-circuited.

[0069] As a non-limiting example, although not illustrated in FIG. 6, the display driving circuit (110) may cause one LED other than the third LED (323) among the plurality of LEDs (320) to emit light within the third light-emitting section (403) instead of the third LED (323) when the third LED (323) has a manufacturing defect. For example, the display driving circuit (110) may provide the first light-emitting signal (331) to the second gate in order to provide the current according to the data voltage to the first LED (321) among the plurality of LEDs (320) using the driving transistor (310) within the third light-emitting section (403) when the third LED (323) has a manufacturing defect. As another example, the display driving circuit (110) may provide a second light emitting signal (332) to the third gate in order to provide the current according to the data voltage to the second LED (322) among the plurality of LEDs (320) using the driving transistor (310) within the third light emitting section (403) when the third LED (323) has a manufacturing defect.

[0070] As a non-limiting example, although not illustrated in FIG. 6, when the third LED (323) has a manufacturing defect, the display driving circuit (110) may refrain from or bypass emitting light within the third light-emitting period (403) and increase the data voltage provided to the first gate. For example, the display driving circuit (110) may provide the first gate with a different data voltage that is higher than the data voltage provided to the first gate within the time period (400) when none of the first LED (321), the second LED (322), and the third LED (323) have manufacturing defects. For example, the display driving circuit (110) can compensate for the avoidance (or bypassing) of light emission in the third light emission period (403) by providing different currents according to the different data voltages to the first LED (321) within the first light emission period (401) and providing the different currents to the second LED (322) within the second light emission period (402) using the driving transistor (310). The compensation will be exemplified in the description of Fig. 7.

[0071] As a non-limiting example, one of the first LED (321) and the second LED (322) within the sub-pixel (300) may have a manufacturing defect, unlike the examples above. For example, when the first LED (321) has a manufacturing defect, the display driving circuit (110) may refrain from emitting light from the first LED (321) within the first light-emitting section (401) and may emit light from the second LED (322) within the second light-emitting section (402). For example, the display driving circuit (110) may compensate for providing light only within the second light-emitting section (402) among the first light-emitting section (401) and the second light-emitting section (402) by using an increase in the data voltage. For another example, when the second LED (322) has a manufacturing defect, the display driving circuit (110) may refrain from emitting light in the first light-emitting section (401) and from emitting light in the second light-emitting section (402). For example, the display driving circuit (110) may compensate for providing light only in the first light-emitting section (401) among the first light-emitting section (401) and the second light-emitting section (402) by using an increase in the data voltage. Such operations may be exemplified in the description of FIG. 7.

[0072] FIG. 7 illustrates an exemplary method for controlling a sub-pixel containing an LED having a manufacturing defect based on compensation of a data voltage.

[0073] Referring further to FIG. 7, the display driving circuit (110) may refrain from emitting light from the first LED (321) within the first light-emitting section (401) and may cause the second LED (322) to emit light within the second light-emitting section (402) when the first LED (321) has a manufacturing defect. For example, the second LED (322) emitting light within the second light-emitting section (402) may provide a higher luminance (Z) than the luminance (L) provided within each of the first light-emitting section (401) and the second light-emitting section (402) when neither the first LED (321) nor the second LED (322) has a manufacturing defect. For example, instead of refraining from emitting light from the first LED (321) within the first emission period (401), the display driving circuit (110) may provide a different data voltage, higher than the data voltage provided to the first gate, to the gate of the driving transistor (310) when both the first LED (321) and the second LED (322) do not have a manufacturing defect. For example, the display driving circuit (110) may provide a second emission signal (332) to the third gate to provide a different current (e.g., about twice the current according to the data voltage) according to the different data voltage to the second LED (322) within the second emission period (402). For example, the second LED (322) may emit light so as to provide a luminance (Z) corresponding to the different current within the second emission period (402) in response to the second emission signal (332). For example, the display driving circuit (110) can compensate for a manufacturing defect of the first LED (321) by changing (or increasing) the data voltage provided to the first gate.

[0074] For example, the display driving circuit (110) may prevent the first LED (321) from emitting light within the first light-emitting section (401) and the second LED (322) from emitting light within the second light-emitting section (402) when the second LED (322) has a manufacturing defect. For example, the first LED (321) emitting light within the first light-emitting section (401) may provide a higher luminance (Z) than the luminance (L) provided within each of the first light-emitting section (401) and the second light-emitting section (402) when neither the first LED (321) nor the second LED (322) has a manufacturing defect. For example, instead of refraining from emitting light from the second LED (322) within the second emission period (402), the display driving circuit (110) may provide a different data voltage, higher than the data voltage provided to the first gate, to the gate of the driving transistor (310) when neither the first LED (321) nor the second LED (322) has a manufacturing defect. For example, the display driving circuit (110) may provide a first emission signal (331) to the second gate to provide a different current according to the different data voltage to the first LED (321) within the first emission period (401). For example, the first LED (321) may emit light to provide a luminance (Z) corresponding to the different current within the first emission period (401) in response to the first emission signal (331). For example, the display driving circuit (110) can compensate for a manufacturing defect of the second LED (322) by changing (or increasing) the data voltage provided to the first gate.

[0075] As a non-limiting example, although not illustrated in FIG. 7, the display driving circuit (110) may, instead of changing the data voltage to cause the second LED (322) to emit light within the second light-emitting section (402) among the first light-emitting section (401) and the second light-emitting section (402) when the first LED (321) has a manufacturing defect, cause the second LED (322) to emit light within both the first light-emitting section (401) and the second light-emitting section (402). For example, the display driving circuit (110) may provide the second light-emitting signal (332) to the third gate to provide a current corresponding to the luminance (L) to the second LED (322) using the driving transistor (310) within both the first light-emitting section (401) and the second light-emitting section (402).

[0076] As a non-limiting example, although not illustrated in FIG. 7, the display driving circuit (110) may, instead of changing the data voltage to cause the first LED (321) to emit light within the first emission period (401) among the first emission period (401) and the second emission period (402) when the second LED (322) has a manufacturing defect, cause the first LED (321) to emit light within both the first emission period (401) and the second emission period (402). For example, the display driving circuit (110) may provide the first emission signal (331) to the second gate to provide a current corresponding to the luminance (L) to the first LED (321) using the driving transistor (310) within both the first emission period (401) and the second emission period (402).

[0077] Referring again to FIG. 3, the sub-pixel (300) can be implemented in various ways. Examples of the sub-pixel (300) can be illustrated within the descriptions of FIGS. 8 and 9.

[0078] Figures 8 and 9 illustrate examples of sub-pixels including two or more light-emitting control transistors.

[0079] Referring to FIG. 8, the sub-pixel (300) may further include a first operation control transistor (801) and a second operation control transistor (802). For example, the first operation control transistor (801) may include a fourth source configured to obtain a driving voltage (e.g., VDD), a fourth gate, and a fourth drain connected to the first source of the driving transistor (310). For example, the second operation control transistor (802) may include a fifth source configured to obtain a driving voltage (e.g., VDD), a fifth gate, and a fifth drain connected to the first source of the driving transistor (310). For example, the display driving circuit (110) may provide a first light-emitting signal (331) to the fourth gate within a first light-emitting period (401), and provide a second light-emitting signal (332) to the fifth gate within a second light-emitting period (402).

[0080] Referring to FIG. 9, the sub-pixel (300) can provide light based on a PWM (pulse width modulation) technique (or control, or driving). For example, the sub-pixel (300) can further include a first operation control transistor (901) and a second operation control transistor (902). For example, the first operation control transistor (901) can include a fourth source configured to obtain a driving voltage (e.g., VDD), a fourth gate, and a fourth drain connected to the first source of the driving transistor (310). For example, the second operation control transistor (902) can include a fifth source configured to obtain a driving voltage (e.g., VDD), a fifth gate, and a fifth drain connected to the first source of the driving transistor (310). For example, the driving transistor (310) in the sub-pixel (300) of FIG. 9, unlike the driving transistor (310) in the sub-pixel (300) of FIGS. 3 and 8, may be configured to obtain one or more pulse signals through the first gate. For example, the display driving circuit (110) may cause the first LED (321) to emit light based on providing the first emission signal (331) to the second gate and the fourth gate within the first emission period (401). For example, the first LED (321) emitting light within the first emission period (401) may provide brightness according to the width of each of the one or more pulse signals. For example, the display driving circuit (110) may cause the second LED (322) to emit light based on providing the second emission signal (332) to the third gate and the fifth gate within the second emission period (402). For example, the second LED (322) emitting light within the second light-emitting section (402) can provide the above brightness.

[0081] Referring back to FIG. 3, the display driver circuit (110) may control the sub-pixels (300) differently depending on the mode of the electronic device (100). For example, the mode may include a first mode and a second mode. For example, the second mode may represent a mode in which an image is displayed on the display panel (120) at a lower power consumption than the power consumed by displaying the image on the display panel (120) based on the first mode. For example, the power consumed during the second mode may be lower than the power consumed during the first mode. For example, the first mode may be referred to as a normal mode, and the second mode may be referred to as a low-power mode. For example, the control of the sub-pixels (300) executed by the display driver circuit (110) during the first mode and the control of the sub-pixels (300) executed by the display driver circuit (110) during the second mode may be exemplified within the description of FIG. 10.

[0082] Figure 10 illustrates examples of the first mode and the second mode provided through the display panel.

[0083] Referring to FIG. 10, as represented by state (1000), the display driving circuit (110) can, during the first mode, provide a first light-emitting signal (331) to the second gate to emit light from the first LED (321) within the first light-emitting period (401), provide a second light-emitting signal (332) to the third gate to emit light from the second LED (322) within the second light-emitting period (402), provide a first light-emitting signal (331) to the second gate to emit light from the first LED (321) within the third light-emitting period (403), and provide a second light-emitting signal (332) to the third gate to emit light from the second LED (322) within the fourth light-emitting period (404).

[0084] For example, as represented by state (1050), the display driving circuit (110) can provide a first emission signal (331) to the second gate to emit light from the first LED (331) within each of the first emission period (401), the second emission period (402), the third emission period (403), and the fourth emission period (404) during the second mode. For example, the number of LEDs used during the first mode can be greater than the number of LEDs used during the second mode. For example, the electronic device (100) can provide the second mode by reducing the number of LEDs used for emission.

[0085] Alternatively, the display driving circuit (110) may, during the second mode, refrain from emitting light within some of the light-emitting sections within the time section (400). For example, the display driving circuit (110) may, during the second mode, refrain from emitting light within each of the first light-emitting section (401) and the third light-emitting section (403), and refrain from or bypass emitting light within each of the second light-emitting section (402) and the fourth light-emitting section (404). For example, the display driving circuit (110) may, during the second mode, refrain from emitting light within each of the second light-emitting section (402) and the fourth light-emitting section (404), and refrain from or bypass emitting light within each of the first light-emitting section (401) and the third light-emitting section (403).

[0086] Referring again to FIG. 1, a sub-pixel and another sub-pixel within the display panel (120) may share one or more LEDs. The sub-pixel and another sub-pixel sharing one or more LEDs may be exemplified within the description of FIG. 11.

[0087] Figure 11 illustrates an example of a sub-pixel sharing an LED and another sub-pixel.

[0088] Referring to FIG. 11, the display panel (120) may include a plurality of pixels. For example, the number of the plurality of pixels may be N (N is a natural number greater than 2). For example, among the plurality of pixels, a pixel (1100-K) in a K-th horizontal line (K is a natural number greater than 1 and less than or equal to N-1) may include a sub-pixel (1101-K), a sub-pixel (1102-K), and a sub-pixel (1103-K). For example, among the plurality of pixels, a pixel (1100-(K+1)) in a (K+1)-th horizontal line may include a sub-pixel (1101-(K+1)), a sub-pixel (1102-(K+1)), and a sub-pixel (1103-(K+1)).

[0089] For example, a sub-pixel (1101-K) may include a first LED (1111) and a second LED (1121) shared with a sub-pixel (1101-(K+1)). For example, a sub-pixel (1101-(K+1)) may include a second LED (1121) and a third LED (1131) shared with a sub-pixel (1101-K). For example, a sub-pixel (1102-K) may include a first LED (1112) and a second LED (1122) shared with a sub-pixel (1102-(K+1)). For example, a sub-pixel (1102-(K+1)) may include a second LED (1122) and a third LED (1132) shared with a sub-pixel (1102-K). For example, sub-pixel (1103-K) may include a first LED (1113) and a second LED (1123) shared with sub-pixel (1103-(K+1)). For example, sub-pixel (1103-(K+1)) may include a second LED (1123) and a third LED (1133) shared with sub-pixel (1103-K).

[0090] For example, sub-pixel (1101-K) and sub-pixel (1101-(K+1)) may share an emission control transistor connected to the second LED (1121), sub-pixel (1102-K) and sub-pixel (1102-(K+1)) may share an emission control transistor connected to the second LED (1122), and sub-pixel (1103-K) and sub-pixel (1103-(K+1)) may share an emission control transistor connected to the second LED (1123). Although not shown in FIG. 11, the display panel (110) may include a switch for controlling the second LED (1121) to emit light for the sub-pixel (1101-K) and the second LED (1121) to emit light for the sub-pixel (1101-(K+1)), a switch for controlling the second LED (1122) to emit light for the sub-pixel (1102-K) and the second LED (1122) to emit light for the sub-pixel (1102-(K+1)), and a switch for controlling the second LED (1123) to emit light for the sub-pixel (1103-K) and the second LED (1123) to emit light for the sub-pixel (1103-(K+1)). The light-emitting control transistor and the switch for controlling the second LED (1121) to emit light for the sub-pixel (1101-K) and the second LED (1121) to emit light for the sub-pixel (1101-(K+1)) shared by the sub-pixel (1101-K) and the switch for controlling the second LED (1121) to emit light for the sub-pixel (1101-(K+1)) can be exemplified within the description of FIG. 12.

[0091] Figure 12 shows an example of a switch used for sharing LEDs.

[0092] Referring to FIG. 12, the sub-pixel (1101-K) may include a driving transistor (1210), a first light-emitting control transistor (1211), a second light-emitting control transistor (1212), a first LED (1111), and a second LED (1121). The sub-pixel (1101-(K+1)) may include a driving transistor (1220), a third light-emitting control transistor (1213), a second LED (1121), and a third LED (1131).

[0093] For example, the driving transistor (1210) may include a first gate configured to obtain a first data voltage (e.g., Vdata1), a first source configured to obtain a driving voltage (e.g., VDD), and a first drain connected to a second source of the first light-emitting control transistor (1211) and connected to a first terminal (1215-1) of the switch (1215). For example, the first light-emitting control transistor (1211) may include a second gate configured to obtain a first light-emitting signal (1231), a second source connected to the first drain and connected to the first terminal (1215-1) of the switch (1215), and a second drain connected to an anode of the first LED (1111). For example, the second light-emitting control transistor (1212) may include a third gate configured to obtain a second light-emitting signal (1232), a third source connected to a third terminal (1215-3) of the switch (1215), and a third drain connected to the anode of the second LED (1121).

[0094] For example, the driving transistor (1220) may include a fourth gate configured to obtain a second data voltage (e.g., Vdata2), a fourth source configured to obtain a driving voltage (e.g., VDD), and a fourth drain connected to a fifth source of a third light-emitting control transistor (1213) and connected to a second terminal (1215-2) of a switch (1215). For example, the third light-emitting control transistor (1213) may include a fifth gate configured to obtain a third light-emitting signal (1233), a fifth source connected to the fourth drain of the driving transistor (1220) and connected to a second terminal (1215-2) of the switch (1215), and a fifth drain connected to an anode of a third LED (1131).

[0095] For example, the display driver circuit (110) can cause the second LED (1121) to emit light for the sub-pixel (1101-K) or cause the second LED (1121) to emit light for the sub-pixel (1101-(K+1)) based on the control of the switch (1215). For example, when the first LED (1111) or the third LED (1131) has a manufacturing defect, the display driver circuit (110) can cause the second LED (1121) to emit light for the sub-pixel (1101-K) or cause the second LED (1121) to emit light for the sub-pixel (1101-(K+1)) based on the control of the switch (1215). The control of the switch (1215) can be exemplified in the descriptions of FIGS. 13, 14A, and 14B.

[0096] Figures 13, 14a, and 14b illustrate exemplary methods of controlling a sub-pixel and other sub-pixels that share an LED.

[0097] Referring to FIG. 13, one time interval (1300) corresponding to the reproduction rate may include a first light emission interval (1301) and a second light emission interval (1302).

[0098] For example, the display driving circuit (110) may provide a first light emitting signal (1231) to the second gate based on timing according to the position of the sub-pixel (1101-K) in order to provide a first current according to the first data voltage to the first LED (1111) using the driving transistor (1210) within the first light emitting section (1301). For example, the first LED (1111) may emit light according to the first current in response to the first light emitting signal (1231). For example, the first LED (1111) may emit light within the first light emitting section (1301) to provide a luminance (U) corresponding to the first current.

[0099] For example, the display driving circuit (110) can control the switch (1215) to connect the second terminal (1215-2) to the third terminal (1215-3) in order to provide the second current according to the second data voltage to the second LED (1121) using the driving transistor (1220) within the first light-emitting section (1301). For example, the control can be executed based on a second control signal provided from the display driving circuit (110) to the switch (1215). For example, the display driving circuit (110) may provide a second emission signal (1232) to the third gate based on timing according to the position of the sub-pixel (1101-(K+1)) while the second terminal (1215-2) is connected to the third terminal (1215-3) in order to provide the second current to the second LED (1121) using the driving transistor (1220) within the first emission period (1301). For example, the second LED (1121) may emit light within the first emission period (1301) to provide a luminance (V) corresponding to the second current.

[0100] For example, since the position of the sub-pixel (1101-(K+1)) is different from the position of the sub-pixel (1101-K), the second light-emitting signal (1232) can be provided within the first light-emitting section (1301) after the first light-emitting signal (1231) is provided.

[0101] For example, the display driving circuit (110) may control the switch (1215) to connect the first terminal (1215-1) to the third terminal (1215-3) after completing providing the second light emitting signal (1232) within the first light emitting period (1301). For example, the control may be executed before the second light emitting signal (1232) is provided to the third gate within the second light emitting period (1302).

[0102] For example, the display driving circuit (110) can control the switch (1215) to connect the first terminal (1215-1) to the third terminal (1215-3) in order to provide the first current to the second LED (1121) using the driving transistor (1210) within the second light-emitting period (1302). For example, the control can be executed based on a first control signal provided from the display driving circuit (110) to the switch (1215). For example, the display driving circuit (110) may provide a second emission signal (1232) to the third gate based on the timing according to the position of the sub-pixel (1101-K) while the first terminal (1215-1) is connected to the third terminal (1215-3) in order to provide the first current to the second LED (1121) using the driving transistor (1210) within the second emission period (1302). For example, the second LED (1121) may emit light within the second emission period (1302) to provide luminance (U) corresponding to the first current.

[0103] For example, the display driving circuit (110) may provide a third light emitting signal (1233) to the fifth gate based on timing according to the position of the sub-pixel (1101-(K+1)) in order to provide the second current to the third LED (1131) using the driving transistor (1220) within the second light emitting period (1302). For example, the third LED (1131) may emit light within the second light emitting period (1302) to provide a luminance (V) corresponding to the second current.

[0104] For example, since the position of the sub-pixel (1101-(K+1)) is different from the position of the sub-pixel (1101-K), the third light-emitting signal (1233) can be provided within the second light-emitting section (1302) after the second light-emitting signal (1232) is provided.

[0105] As described above, the electronic device (100) can reduce the number of LEDs included in the display panel (120) through one or more LEDs shared by two sub-pixels.

[0106] When the first LED (1111) has a manufacturing defect unlike the second LED (1121) and the third LED (1131), the display driving circuit (110) may perform operations that are partially different from the operations illustrated in the description of FIG. 13.

[0107] For example, referring to FIG. 14a, the display driving circuit (110) can refrain from or bypass emitting light from the first LED (1111) within the first emission section (1301).

[0108] Although not illustrated in FIG. 14a, the display driving circuit (110) may also emit light from the second LED (1121) within the second emission section (1302) to provide a luminance higher than the luminance (U) using the operations exemplified in the description of FIG. 7. However, the present invention is not limited thereto.

[0109] When the third LED (1131) has a manufacturing defect unlike the first LED (1111) and the second LED (1121), the display driving circuit (110) may perform operations that are partially different from the operations illustrated in the description of FIG. 13.

[0110] For example, referring to FIG. 14b, the display driving circuit (110) may refrain from or bypass emitting light from the third LED (1131) within the second emission section (1302).

[0111] Although not illustrated in FIG. 14b, the display driving circuit (110) may also emit light from the second LED (1121) within the first emission section (1301) to provide a luminance higher than the luminance (V) using the operations exemplified in the description of FIG. 7. However, the present invention is not limited thereto.

[0112] Referring back to FIG. 1, the quality of the display on a portion of the display panel (120) may be lower than the quality of the display on another portion of the display panel (120). For example, current leakage may be caused by external light from at least some of the LEDs within the display panel (120). For example, the current leakage may reduce the brightness provided based on emitting at least some of the LEDs. As a non-limiting example, the current leakage may be caused while providing a relatively high brightness through the display panel (120). As another example, color deviation may occur on the display panel (120) due to errors in metal etching for the display panel (120). For another example, if the electronic device (100) is AR glasses or a VST (video see through) device, the brightness provided through the edge area of ​​the display panel (120) may be lower than the brightness provided through the center area of ​​the display panel (120), depending on the optical characteristics.

[0113] For example, the electronic device (100) may utilize LEDs within the display panel (120) to compensate for brightness differences on the display panel (120). For example, the compensation may be performed by the display driving circuit (110). The compensation may be exemplified within the description of FIG. 15.

[0114] Figure 15 illustrates an exemplary method for compensating the luminance of a border area of ​​a display panel.

[0115] Referring to FIG. 15, the display panel (120) may include a plurality of LEDs. For example, the plurality of LEDs may include a first set of LEDs having a manufacturing defect and a second set of LEDs not having the manufacturing defect. Since each of the plurality of LEDs may be a micro LED and may have a relatively small size, a relatively large number of the second set of LEDs (1560) may be included to compensate for a decrease in the quality of an image displayed on the display panel (120) due to the first set of LEDs. Since the number of the second set of LEDs (1560) may be relatively large, a portion (1570) of the second set of LEDs (1560) may be used to compensate for the brightness of the display panel (120).

[0116] For example, as represented by chart (1500), the luminance of a border region (1520) of the display panel (120) may be lower than the luminance of a center region (1510) of the display panel (120). For example, the display driver circuit (120) may light a portion (1570) of the second set of LEDs (1560) to compensate for the lower luminance of the border region (1520) than the luminance of the center region (1510). For example, the display driver circuit (120) may reduce the difference between the luminance of the center region (1510) and the luminance of the border region (1520) based on lighting a portion (1570) of the second set of LEDs (1560), as represented by chart (1550).

[0117] Referring back to FIG. 1, the display panel (120) may provide a mode for brightness higher than the reference brightness to provide enhanced visibility when the ambient illuminance of the electronic device (100) is higher than the reference illuminance. For example, the mode may be referred to as HBM (high brightness mode). For example, the electronic device (100) may utilize LEDs within the display panel (120) for the mode. The mode may be provided through LEDs controlled by the display driving circuit (110). A method for providing the mode may be exemplified within the description of FIG. 16.

[0118] FIG. 16 illustrates an exemplary method for providing a mode for luminance above a reference luminance using a display panel.

[0119] Referring to FIG. 16, the display panel (120) may include a plurality of LEDs. Since each of the plurality of LEDs may be a micro LED and may have a relatively small size, the display driving circuit (110) may cause some (1610) of the plurality of LEDs to emit light while the illuminance around the electronic device (100) is lower than or equal to the reference illuminance, as indicated by the state (1600), and may not cause the remaining portion (1620) of the plurality of LEDs to emit light. For example, the illuminance of the remaining portion (1620) of the plurality of LEDs may be limited by the display driving circuit (110) while the illuminance is lower than or equal to the reference illuminance. As another example, the illuminance of the remaining portion (1620) of the plurality of LEDs may be limited by the display driving circuit (110) while the remaining capacity of the rechargeable battery of the electronic device (100) is lower than the reference capacity.

[0120] For example, the display driving circuit (110) can change the state (1600) to the state (1650) based on information, signals, or data obtained from the processor of the electronic device (100). For example, the state (1650) can indicate a state of providing the HBM. For example, the display driving circuit (110) can provide the HBM by changing the state (1600) to the state (1650) based on the information, the signal, or the data obtained from the processor when the data obtained through the illuminance sensor of the electronic device (100) indicates illuminance higher than the reference illuminance. For example, the display driving circuit (110) can cause not only a portion (1610) of the plurality of LEDs but also a remaining portion (1620) of the plurality of LEDs to emit light during the HBM. For example, the electronic device (100) can provide enhanced visibility in an environment having an illuminance higher than the reference illuminance by emitting the remaining portion (1620) of the plurality of LEDs during the HBM using the display driving circuit (110).

[0121] Referring back to FIG. 1, some of the plurality of LEDs within the display panel (120) may have manufacturing defects, as described above. For example, since each of the plurality of LEDs is a micro LED and has a relatively small size, each of the sub-pixels within the display panel (120) may have a structure to reduce the occurrence of dead areas within the display panel (120) due to some of the plurality of LEDs having manufacturing defects. For example, the manufacturing defect may include some of the plurality of LEDs being short-circuited. The structure may be exemplified within the descriptions of FIGS. 17 to 20.

[0122] Figures 17 to 20 illustrate sub-pixels within a display panel of an exemplary electronic device including three or more LEDs.

[0123] Referring to FIG. 17, the display panel (120) may include sub-pixels (1700). For example, each of the sub-pixels (1700) may include a driving transistor (1710) including a gate configured to obtain a data voltage (e.g., Vdata), a source configured to obtain a driving voltage (e.g., VDD), and a drain. For example, each of the sub-pixels (1700) may include a plurality of LEDs, including a first LED (1731) having a first anode and a first cathode connected to a node (1715) connectable to the drain, a second LED (1732) having a second anode and a second cathode connected to the first cathode, a third LED (1733) having a third anode and a third cathode connected to the node (1715) and disconnected from the first cathode, and a fourth LED (1734) having a fourth anode and a fourth cathode connected to the third cathode and disconnected from the first cathode.

[0124] For example, the display driving circuit (110) can cause the second LED (1732), the third LED (1733), and the fourth LED (1734) to emit light according to the data voltage and the driving voltage by using the driving transistor (1710) when the first LED (1731) among the plurality of LEDs is short-circuited. For example, the display driving circuit (110) can cause the first LED (1731), the third LED (1733), and the fourth LED (1734) to emit light according to the data voltage and the driving voltage by using the driving transistor (1710) when the second LED (1732) among the plurality of LEDs is short-circuited.

For example, the display driving circuit (110) can cause the first LED (1731) and the third LED (1733) to emit light according to the data voltage and the driving voltage by using the driving transistor (1710) when the second LED (1732) and the fourth LED (1734) among the plurality of LEDs are short-circuited.

[0125] For example, each of the sub-pixels (1700) may further include an emission control transistor (1720) having another gate configured to receive an emission signal (1780) from the display driving circuit (110), another source connected to the drain, and another drain connected to the first anode and the third anode, respectively, via a node (1715).

For example, each of the sub-pixels (1800) may include a driving transistor (1810) including a gate configured to obtain a data voltage (e.g., Vdata), a source configured to obtain a driving voltage (e.g., VDD), and a drain.

[0128] For example, each of the sub-pixels (1800) may further include an emission control transistor (1820) having another gate configured to receive an emission signal (1880) from the display driving circuit (110), another source connected to the drain, and another drain connected to the first anode and the third anode, respectively, via a node (1815).

[0129] Referring to FIG. 19, the display panel (120) may include sub-pixels (1900). For example, each of the sub-pixels (1900) may include a driving transistor (1910) including a gate configured to obtain a data voltage (e.g., Vdata), a source configured to obtain a driving voltage (e.g., VDD), and a drain.
