FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the disclosure. Referring to FIG. 1, an electronic device 100 includes a control module 110, a light emission driving element 120, a light emitting module 130, a detection element 140, a first memory element 150, a display driving element 160, and a display panel 170. The control module 110 is electrically connected to a vehicle control unit (VCU) 10, the light emission driving element 120, the detection element 140, the first memory element 150, and the display driving element 160. The light emission driving element 120 is also electrically connected to the light emitting module 130. The detection element 140 is also electrically connected to the light emitting module 130. The display driving element 160 is also electrically connected to the display panel 170.

In the embodiment, the control module 110 includes a timing controller (TCON) 111 and a light emission controller 112. The timing controller 111 is electrically connected to the light emission controller 112, the vehicle control unit 10, the light emission driving element 120, the first memory element 150, and the display driving element 160. The timing controller 111 may include a second memory element 1111. The light emission controller 112 is also electrically connected to the detection element 140 and the first memory element 150. In the embodiment, the vehicle control unit (VCU) 10 may provide display data to the electronic device 100, but the disclosure is not limited thereto. The timing controller 111 may control the display driving element 160 to drive the display panel 170 according to the display data.

In an embodiment, the control module 110 may be implemented in the form of an integrated circuit (IC) or a microcontroller unit (MCU). In another embodiment, at least one of the detection element 140, the first memory element 150, and the light emission controller 112 may also be disposed in the control module 110 or the timing controller 111, but the disclosure is not limited thereto.

In the embodiment, the light emitting module 130 may include a first substrate and multiple light emitting elements, and the light emitting elements may be disposed on the first substrate, wherein the first substrate may be a circuit substrate, but the disclosure is not limited thereto. The light emitting module 130 may be a light emitting diode (LED) backlight module or an organic light emitting diode (OLED) backlight module, but the disclosure is not limited thereto. The light emitting element may include a light emitting diode. The light emission driving element 120 may include a light emitting diode driving circuit. The light emission driving element 120 may generate a corresponding driving signal according to a control signal output by the control module 110, and drive the light emitting elements of the light emitting module 130.

In the embodiment, the display panel 170 may include a second substrate and multiple pixel elements, and the pixel elements may be disposed on the second substrate, wherein the material of the second substrate may be glass, quartz, ceramic, sapphire, polymer (for example, polyimide (PI), polyethylene terephthalate (PET)), other suitable materials, or a combination thereof, but the disclosure is not limited thereto. The display panel 170 may be a liquid crystal display (LCD) panel, but the disclosure is not limited thereto. The pixel element may include a liquid crystal unit. The display driving element 160 may include a liquid crystal driving circuit. The display driving element 160 may generate a corresponding driving signal according to the display data output by the control module 110, and drive the pixel elements of the display panel 170.

In the embodiment, the detection element 140 may include, for example, a light emitting diode, a transistor, a charge coupled device, etc. and may detect whether each of the pixel elements in the light emitting module 130 is defective through detecting an optical signal or an electrical signal. When the detection element 140 detects that at least one of the light emitting elements is defective, the detection element 140 may output an adjustment signal to the control module 110, so that the control module 110 may control at least one of the light emission driving element 120 and the display driving element 160 according to the adjustment signal, so as to adjust at least one of a brightness compensation distribution (that is, change a light emitting brightness ratio of at least one specific light emitting element) of the light emitting module 130 and a pixel compensation distribution (that is, change an aperture ratio of at least one specific pixel element, wherein the magnitude of a pixel value may correspond to the aperture ratio) of the display panel 180. It should be noted that the defective pixel element may refer to a pixel element that cannot emit light normally or emits insufficient light.

In the embodiment, the first memory element 150 may be a flash memory, and the second memory 1111 may be a random access memory (RAM), but the disclosure is not limited thereto.

The first memory element 150 may pre-store at least one of a first brightness compensation table and a first pixel compensation table. The second memory element 111 may store at least one of a new first brightness compensation table and a new first pixel compensation table each time the electronic device 100 is activated.

Specifically, regarding the first brightness compensation table, during the production process of the light emitting module 130, the manufacturer may perform light emitting quality detection on the light emitting module 130, and may establish the first brightness compensation table according to the light emitting efficiency or brightness of the light emitting elements of the light emitting module 130. For example, for a light emitting element with lower brightness or other light emitting elements around the light emitting element with lower brightness, the first brightness compensation table may have a higher corresponding brightness compensation parameter. In contrast, for a light emitting element with higher brightness or other light emitting elements around the light emitting element with higher brightness, the first brightness compensation table may have a lower corresponding brightness compensation parameter, so that the light emitting module 130 can implement uniform overall light emitting brightness after leaving the factory.

Regarding the first pixel compensation table, the manufacturer may also establish the first pixel compensation table according to the light emitting efficiency or brightness of the light emitting elements of the light emitting module 130. For example, for a light emitting element with lower brightness, the first pixel compensation table may have a higher pixel compensation parameter to correspond to at least one pixel element corresponding to the light emitting element with lower brightness (in other words, the aperture ratio of at least one pixel element corresponding to the light emitting element with insufficient brightness may be increased, so that the amount of light passing through the at least one pixel element may be increased). In contrast, for a light emitting element with higher brightness, the first pixel compensation table may have a lower pixel compensation parameter to correspond to at least another pixel element corresponding to the light emitting element with higher brightness (in other words, the aperture ratio of at least one pixel element corresponding to the light emitting element with higher brightness may be lowered or maintained at a normal aperture ratio, so that the amount of light passing through the at least one pixel element may be reduced or maintained at normal).

FIG. 2 is a flowchart of an operating method of an electronic device according to an embodiment of the disclosure. FIG. 3A is a schematic diagram of a light emitting module according to an embodiment of the disclosure. FIG. 3B is a schematic diagram of a display panel according to an embodiment of the disclosure. Referring to FIG. 1 to FIG. 3B, at least part of the light emitting module 130 may be, for example, as shown in FIG. 3A, wherein the light emitting module 130 includes a first substrate 131 and multiple light emitting elements 132. At least part of the display panel 170 may be, for example, as shown in FIG. 3B, wherein the display panel 170 includes a second substrate 171 and multiple pixel elements 172. It is worth noting that the display panel 170 may be disposed above the light emitting module 130, and one light emitting element 132 of the light emitting module 130 may correspond to one or more pixel elements 172 of the display panel 170 in a light emission direction (also referred to as a display direction), but the disclosure is not limited thereto. The light emitting element 132 of the light emitting module 130 may serve as a light source of one or more pixel elements 172 of the display panel 170.

In the embodiment, the electronic device 100 may execute steps S210 to S230 below to effectively drive the light emitting module 130. In step S210, the detection element 140 may detect whether the light emitting elements 132 of the light emitting module 130 are defective. In step S220, in response to the detection element 140 detecting that at least one of the light emitting elements 132 is defective, the detection element 140 may output the adjustment signal to the control module 110. As shown in FIG. 3A, assuming that the detection element 140 detects that a light emitting element 132″ is a defective light emitting element, the detection element 140 outputs the corresponding adjustment signal to the control module 110. In step S230, the control module 110 may generate the new first brightness compensation table according to the adjustment signal and the first brightness compensation table. In the embodiment, the detection element 140 may output the corresponding adjustment signal to the light emission controller 112 of the control module 110, wherein the adjustment signal may include a coordinate parameter corresponding to the defective light emitting element 132″. The light emission controller 112 may modify the first brightness compensation table according to the coordinate parameter of the defective light emitting element 132″ to generate the new first brightness compensation table, and store the new first brightness compensation table in the first memory element 150 (please refer to FIG. 1).

For example, referring to FIG. 3A and FIG. 4 together, FIG. 4 is a schematic diagram of modifying a brightness compensation table according to an embodiment of the disclosure. The first memory element 150 may pre-store a first brightness compensation table 401, wherein multiple first brightness compensation parameters of the first brightness compensation table 401 may be respectively used for the light emitting elements 132 in FIG. 3A. In the first brightness compensation table 401, the first brightness compensation parameters corresponding to the light emitting elements 132 disposed at the border of the first substrate 131 may be, for example, 1.1, the first brightness compensation parameters corresponding to the light emitting elements 132 disposed at the four corners of the first substrate 131 may be, for example, 2.2, and the first brightness compensation parameters corresponding to the light emitting elements 132 disposed at other positions of the first substrate 131 may be, for example, 1.0. The brightness compensation parameter may be used to represent a ratio of compensated brightness to normal brightness, but the disclosure is not limited thereto. FIG. 4 is only used to represent a numerical example, and the numerical representation of the brightness compensation table of the disclosure is not limited thereto.

When the detection element 140 detects that the light emitting element 132″ is a defective light emitting element, the detection element 140 may output the coordinate parameter corresponding to the light emitting element 132″ to the light emission controller 112, so that the light emission controller 112 may generate a second brightness compensation table 402 according to the coordinate parameter corresponding to the light emitting element 132″, and multiply the first brightness compensation parameters of the first brightness compensation table 401 by multiple corresponding second brightness compensation parameters of the second brightness compensation table 402 one-to-one to generate a new first brightness compensation table 403 having multiple new first brightness compensation parameters. In the second brightness compensation table 402, the second brightness compensation parameter corresponding to the defective light emitting element 132″ may be 0, and the second brightness compensation parameter corresponding to at least one light emitting element adjacent to the defective light emitting element may be greater than the second brightness compensation parameter of a normal light emitting element not adjacent to the defective light emitting element. As shown in the second brightness compensation table 402 in FIG. 4, the second brightness compensation parameters of the light emitting elements adjacent to the defective light emitting element may be 1.1, and the second brightness compensation parameters of the normal light emitting elements not adjacent to the defective light emitting element may be 1.0.

However, the numerical distribution of the second brightness compensation parameters of the second brightness compensation table of the disclosure is not limited to as shown in FIG. 4. In an embodiment, the values of the second brightness compensation parameters of the second brightness compensation table may progressively decrease in sequence toward the periphery with the defective light emitting element as the center, and the manner of progressively decreasing the values is not limited in the disclosure. For another example, in another embodiment, the values of the second brightness compensation parameters of the second brightness compensation table may also have the same higher values corresponding to multiple parameters within a preset range of the defective light emitting element.

In this regard, the light emission controller 112 may store the new first brightness compensation table 403 in the first memory element 150, and the first memory element 150 may replace the first brightness compensation table 401 with the new first brightness compensation table 403. Next, the timing controller 111 may read the first memory element 150 to store the new first brightness compensation table 403 in the second memory element 1111, generate corresponding control signals according to multiple new first brightness compensation parameters of the new first brightness compensation table 403, and output the corresponding control signals to the light emission driving element 120, so that the light emission driving element 120 may drive the light emitting elements 132 of the light emitting module 130 according to the corresponding control signals. As shown in the new first brightness compensation table 403 in FIG. 4, since the brightness compensation parameter corresponding to the defective light emitting element is 0, the light emitting module 130 does not drive the defective light emitting element and performs brightness compensation through increasing brightness of multiple light emitting elements adjacent to the defective light emitting element. In this way, the influence of uneven brightness caused by the defective light emitting element can be effectively reduced.

In addition, the timing controller 111 of the embodiment may also read the original first pixel compensation table stored in the first memory element 150, and control the display driving element 160 to drive the display panel 170 according to the original first pixel compensation table.

However, in an embodiment, the light emission controller 112 may also output the coordinate parameter corresponding to the defective light emitting element to the timing controller 111. The timing controller 111 may have a corresponding arithmetic algorithm, read the first brightness compensation table 401 stored in the first memory element 150 each time the electronic device 100 is reactivated, and store the first brightness compensation table 401 in the second memory element 1111. The timing controller 111 may modify the first brightness compensation table 401 according to the coordinate parameter corresponding to the defective light emitting element 132″ to generate the new first brightness compensation table 403. The timing controller 111 may generate the new first brightness compensation table 403 in the manner described above in FIG. 4, and store the new first brightness compensation table 403 in the second memory element 1111. Furthermore, the timing controller 111 or the light emission controller 112 may also store at least one of the second brightness compensation table 402 and the new first brightness compensation table 403 in the first memory element 150.

In addition, in another embodiment, the light emission controller 112 or the timing controller 111 may also generate the new first brightness compensation table 403 through directly modifying the first brightness compensation table 401 without establishing the second brightness compensation table 402.

FIG. 5 is a flowchart of an operating method of an electronic device according to an embodiment of the disclosure. Referring to FIG. 1, FIG. 3A, FIG. 3B, and FIG. 5, in the embodiment, the electronic device 100 may execute steps S510 to S540 below to effectively drive the light emitting module 130 and the display panel 170. In step S510, the detection element 140 may detect whether the light emitting elements 132 of the light emitting module 130 are defective. In step S520, in response to the detection element 140 detecting that at least one of the light emitting elements 132 is defective, the detection element 140 may output the adjustment signal to the control module 110. As shown in FIG. 3A, assuming that the detection element 140 detects that the light emitting element 132″ is a defective light emitting element, the detection element 140 outputs the corresponding adjustment signal to the control module 110. In step S530, the control module 110 may generate the new first brightness compensation table according to the adjustment signal and the first brightness compensation table. In step S540, the control module 110 may generate the new first pixel compensation table according to the adjustment signal and the first pixel compensation table.

In the embodiment, the detection element 140 may output the corresponding adjustment signal to the light emission controller 112 of the control module 110, wherein the adjustment signal may include the coordinate parameter corresponding to the defective light emitting element 132″. The light emission controller 112 may modify the first brightness compensation table and the first pixel compensation table according to the coordinate parameter of the defective light emitting element 132″ to generate the new first brightness compensation table and the new first pixel compensation table, and store the new first brightness compensation table and the new first pixel compensation table in the first memory element 150.

The manner of generating the new first brightness compensation table may be as described in the embodiment of FIG. 4 above, so there will be no elaboration herein. Regarding the manner of generating the new first pixel compensation table, for example, referring to FIG. 6 together, FIG. 6 is a schematic diagram of modifying a pixel compensation table according to an embodiment of the disclosure. The first memory element 150 may pre-store a first pixel compensation table 601, wherein multiple first brightness compensation parameters of the first pixel compensation table 601 may be respectively used for the pixel elements 172 in FIG. 3B. In the first pixel compensation table 601, multiple first pixel compensation parameters corresponding to the pixel elements 172 may be, for example, 1. The pixel compensation parameter may be used to represent a ratio of an aperture ratio (or a pixel value or a grayscale value) of a compensated pixel to an aperture ratio of a normal pixel, but the disclosure is not limited thereto. FIG. 6 is only used to represent a numerical example, and the numerical representation of the pixel compensation table of the disclosure is not limited thereto.

When the detection element 140 detects that the light emitting element 132″ is a defective light emitting element, the detection element 140 may output the coordinate parameter corresponding to the light emitting element 132″ to the light emission controller 112, so that the light emission controller 112 may generate a second pixel compensation table 602 according to the coordinate parameter corresponding to the light emitting element 132″, and multiply the first pixel compensation parameters of the first pixel compensation table 601 by multiple corresponding second pixel compensation parameters of the second pixel compensation table 602 one-to-one to generate a new first pixel compensation table 603 having multiple new first pixel compensation parameters. In the second pixel compensation table 602, multiple second pixel compensation parameters of multiple pixel elements 172″ corresponding to the defective light emitting element 132″ are higher than other second pixel compensation parameters corresponding to the normal light emitting element.

As shown in the second pixel compensation table 602 of FIG. 3B and FIG. 6, the second

pixel compensation parameter of the pixel element at the center position among the pixel elements 172″ corresponding to the light emitting element 132″ may be 1.5, the second pixel compensation parameters of other pixel elements among the pixel elements 172″ corresponding to the light emitting element 132″ may be 1.1, and the other second pixel compensation parameters corresponding to the normal light emitting element may be 1.0.

However, the numerical distribution of the second pixel compensation parameters of the second pixel compensation table of the disclosure is not limited to as shown in FIG. 6. In an embodiment, the values of the second pixel compensation parameters of the second pixel compensation table may progressively decrease in sequence toward the periphery with the defective light emitting element as the center, and the manner of progressively decreasing the values is not limited in the disclosure. For another example, in another embodiment, the values of the second pixel compensation parameters of the second pixel compensation table may also have the same higher values corresponding to multiple parameters within a preset range of the defective light emitting element.

In this regard, the light emission controller 112 may store the new first pixel compensation table 603 in the first memory element 150, and the first memory element 150 may replace the first pixel compensation table 601 with the new first pixel compensation table 603. Next, the timing controller 111 may read the first memory element 150 to store the new first pixel compensation table 603 in the second memory element 1111, generate the corresponding display data according to the new first pixel compensation parameters of the new first pixel compensation table 603, and output the corresponding display data to the display driving element 160, so that the display driving element 160 may drive the pixel elements 172 of the display panel 170 according to the corresponding display data. As shown in the new first pixel compensation table 603 of FIG. 6, since the values of the pixel compensation parameters of the pixel elements corresponding to the defective light emitting element are higher than other pixel compensation parameters, the pixel elements of the display panel 170 corresponding to positions with light emission defects may be correspondingly adjusted to have higher aperture ratios. In this way, uneven display brightness of a display image caused by the defective light emitting element can be effectively reduced.

However, in an embodiment, the light emission controller 112 may also output the coordinate parameter corresponding to the defective light emitting element to the timing controller 111. The timing controller 111 may have a corresponding arithmetic algorithm, read the first pixel compensation table 601 stored in the first memory element 150 each time the electronic device 100 is reactivated, and store the first pixel compensation table 601 in the second memory element 1111. The timing controller 111 may modify the first pixel compensation table 601 according to the coordinate parameter corresponding to the defective light emitting element 132″ to generate the new first pixel compensation table 603. The timing controller 111 may generate the new first pixel compensation table 603 in the manner described above in FIG. 6, and store the new first pixel compensation table 603 in the second memory element 1111. Furthermore, the timing controller 111 or the light emission controller 112 may also store at least one of the second pixel compensation table 602 and the new first pixel compensation table 603 in the first memory element 150.

In addition, in another embodiment, the light emission controller 112 or the timing controller 111 may also generate the new first pixel compensation table 603 through directly modifying the first pixel compensation table 601 without establishing the second pixel compensation table 602.

FIG. 7 is a flowchart of an operating method of an electronic device according to an embodiment of the disclosure. Referring to FIG. 1, FIG. 3A, FIG. 3B, and FIG. 7, in the embodiment, the electronic device 100 may execute steps S710 to S730 below to effectively drive the display panel 170. In step S710, the detection element 140 may detect whether the light emitting elements 132 of the light emitting module 130 are defective. In step S720, in response to the detection element 140 detecting that at least one of the light emitting elements 132 is defective, the detection element 140 may output the adjustment signal to the control module 110. As shown in FIG. 3A, assuming that the detection element 140 detects that the light emitting element 132″ is a defective light emitting element, the detection element 140 outputs the corresponding adjustment signal to the control module 110. In step S730, the control module 110 may generate the new first pixel compensation table according to the adjustment signal and the first pixel compensation table.

In the embodiment, the detection element 140 may output the corresponding adjustment signal to the light emission controller 112 of the control module 110, wherein the adjustment signal may include the coordinate parameter corresponding to the defective light emitting element 132″. The light emission controller 112 may modify the first pixel compensation table according to the coordinate parameter corresponding to the defective light emitting element 132″ to generate the new first pixel compensation table, and store the new first pixel compensation table in the first memory element 150.

The manner of generating the new first pixel compensation table may be as described in the embodiment of FIG. 6 above, so there will be no elaboration herein. Moreover, as shown in the new first pixel compensation table 603 of FIG. 6, since the values of the pixel compensation parameters of the pixel elements corresponding to the defective light emitting element are higher than the other pixel compensation parameters, the pixel elements of the display panel 170 corresponding to the positions with the light emission defects may be correspondingly adjusted to have higher aperture ratios. In this way, the uneven display brightness of the display image caused by the defective light emitting element can be effectively reduced.

FIG. 10 is a schematic diagram of a light emitting module according to an embodiment of the disclosure. Referring to FIG. 10, the light emitting module of the disclosure may also implement the architecture shown in FIG. 10. In the embodiment, a light emitting module 1000 includes a substrate 1001 and multiple light emitting elements, wherein the light emitting elements are disposed on the substrate 1001. In the embodiment, the light emitting elements may include multiple light emitting elements 1002 corresponding to an active area (AA) 1010 of a display panel and also include multiple light emitting elements 1003 corresponding to a peripheral area outside the active area 1010 of the display panel. In this regard, if backlight is provided to the border position corresponding to the active area 1010 of the display panel by only the light emitting elements 1002 corresponding to the active area 1010, brightness thereof may be insufficient. Therefore, the light emitting module 1000 of the embodiment is further provided with the light emitting elements 1003 in the peripheral area outside the active area 1010 to effectively compensate for the brightness at the border position corresponding to the active area 1010. It should be noted that “corresponding to” described here may mean that a projection of an element or/and a region in a normal direction of an electronic device may overlap with another element or/and region. For example, the light emitting elements 1002 may correspond to the active area of the display panel. In other words, the projections of the light emitting elements 1002 in the normal direction of the electronic device may overlap with the active area of the display panel.

FIG. 11 is a schematic diagram of modifying a brightness compensation table according to an embodiment of the disclosure. Referring to FIG. 11, based on the architecture of the light emitting module 1000 in FIG. 10, the brightness compensation table of the disclosure may also be as shown in FIG. 11. In the embodiment, multiple first brightness compensation parameters of a first brightness compensation table 1101 may include the light emitting elements 1002 for use in the active region 1010 as shown in FIG. 10 and the light emitting elements 1003 for use outside the active region 1010.

In other words, assuming that the position of the defective light emitting element is located at the border position of the active area 1010 as shown in FIG. 10, the embodiment can effectively perform brightness compensation through increasing the brightness of at least one light emitting element 1003 adjacent to the position of the defective light emitting element outside the active area 1010.

In summary, the electronic device of the disclosure automatically detect whether the light emitting elements of the light emitting module are defective, and can automatically correspondingly adjust at least one of the brightness compensation table and the pixel compensation table, so as to effectively reduce the influence of uneven brightness caused by the defective light emitting element, and enable the display image to present uniform display brightness.
