[0054] Figure 1 is a schematic diagram of an electronic device according to an embodiment of the present disclosure. Figure 1 The electronic device 100 includes a control module 110, a light-emitting driving element 120, a light-emitting module 130, a detection element 140, a first storage 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-emitting driving element 120, the detection element 140, the first storage element 150, and the display driving element 160. The light-emitting 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.

[0055] In the present embodiment, the control module 110 includes a timing controller (TCON) 111 and a light controller 112. The timing controller 111 is electrically connected to the light controller 112, the vehicle control unit 10, the light driving element 120, the first storage element 150 and the display driving element 160. The timing controller 111 may include a second storage element 1111. The light controller 112 is also electrically connected to the detection element 140 and the first storage element 150. In the present embodiment, the vehicle control unit (VCU) 10 may provide display data to the electronic device 100, but the present 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.

[0056] In one 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 storage element 150, and the light controller 112 may also be disposed in the control module 110 or the timing controller 111, but the present disclosure is not limited thereto.

[0057] In the present embodiment, the light emitting module 130 may include a first substrate and a plurality of light emitting elements, and the plurality of light emitting elements may be arranged on the first substrate, wherein the first substrate may be a circuit substrate, but the present 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 present disclosure is not limited thereto. The light emitting element may include a light emitting diode. The light emitting driving element 120 may include a light emitting diode driving circuit. The light emitting driving element 120 may generate a corresponding driving signal according to a control signal output by the control module 110, and drive the plurality of light emitting elements of the light emitting module 130.

[0058] In the present embodiment, the display panel 170 may include a second substrate and a plurality of pixel elements, and the plurality of pixel elements may be arranged on the second substrate, wherein the material of the second substrate may be glass, quartz, ceramic, sapphire, polymer (e.g., polyimide (PI), polyethylene terephthalate (PET)), other suitable materials or combinations thereof, but the present disclosure is not limited thereto. The display panel 170 may be a liquid crystal display panel (LCD), but the present 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 plurality of pixel elements of the display panel 170.

[0059] In the present embodiment, the detection element 140 may include, for example, a light emitting diode, a transistor or a charge coupled device, and may detect whether each of the plurality of pixel elements in the light emitting module 130 has a defect by detecting an optical signal or an electrical signal. When the detection element 140 detects that at least one of the plurality of light emitting elements has a defect, 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 emitting driving element 120 and the display driving element 160 according to the adjustment signal, so as to adjust at least one of the brightness compensation distribution of the light emitting module 130 (i.e., changing the light emitting brightness ratio of at least one specific light emitting element) and the pixel compensation distribution of the display panel 180 (i.e., changing the aperture ratio of at least one specific pixel element, wherein the size of the pixel value may correspond to the aperture ratio). It is worth noting that the defective pixel element may refer to a situation where the pixel element cannot emit light normally or the light emission level is insufficient.

[0060] In the present embodiment, the first storage element 150 may be a flash memory, and the second memory 1111 may be a random access memory (RAM), but the present disclosure is not limited thereto. The first storage element 150 may pre-store at least one of the first brightness compensation table and the first pixel compensation table. The second storage 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 started.

[0061] Specifically, regarding the first brightness compensation table, during the production process of the light-emitting module 130, the manufacturer may perform a light-emitting quality test on the light-emitting module 130, and may establish a first brightness compensation table based on the light-emitting efficiency or brightness of the plurality of 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 a light-emitting element with lower brightness, the first brightness compensation table may have a higher corresponding brightness compensation parameter. Conversely, for a light-emitting element with higher brightness or other light-emitting elements around a 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 achieve uniform overall light-emitting brightness after leaving the factory.

[0062] Regarding the first pixel compensation table, the manufacturer may also establish the first pixel compensation table according to the luminous efficiency or brightness of the multiple 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 corresponding 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). Conversely, for a light-emitting element with higher brightness, the first pixel compensation table may have a lower pixel compensation parameter corresponding 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).

[0063] Figure 2 is a flowchart of an operating method of an electronic device according to an embodiment of the present disclosure. Figure 3A is a schematic diagram of a light emitting module according to an embodiment of the present disclosure. Figure 3B Schematic diagram of a display panel according to an embodiment of the present disclosure. Figures 1 to 3B At least a portion of the light emitting module 130 may be, for example, Figure 3A As shown, the light emitting module 130 includes a first substrate 131 and a plurality of light emitting elements 132. At least a portion of the display panel 170 may be, for example, Figure 3B As shown, the display panel 170 includes a second substrate 171 and a plurality of pixel elements 172. It is worth noting that the display panel 170 can be disposed above the light emitting module 130, and one light emitting element 132 of the light emitting module 130 can correspond to one or more pixel elements 172 of the display panel 170 in the light emitting direction (or display direction), and the present disclosure is not limited thereto. One light emitting element 132 of the light emitting module 130 can serve as a light source for one or more pixel elements 172 of the display panel 170.

[0064] In this embodiment, the electronic device 100 may perform the following steps S210-S230 to effectively drive the light emitting module 130. In step S210, the detection element 140 may detect whether the plurality of light emitting elements 132 of the light emitting module 130 have defects. In step S220, in response to the detection element 140 detecting that at least one of the plurality of light emitting elements 132 has a defect, the detection element 140 may output an adjustment signal to the control module 110. Figure 3AAs shown, assuming that the detection element 140 detects that the light-emitting element 132" is a defective light-emitting element, the detection element 140 outputs a corresponding adjustment signal to the control module 110. In step S230, the control module 110 may generate a new first brightness compensation table according to the adjustment signal and the first brightness compensation table. In the present embodiment, the detection element 140 may output a corresponding adjustment signal to the light-emitting controller 112 of the control module 110, wherein the adjustment signal may include coordinate parameters corresponding to the defective light-emitting element 132". The light-emitting controller 112 may modify the first brightness compensation table according to the coordinate parameters corresponding to the defective light-emitting element 132" to generate a new first brightness compensation table, and store the new first brightness compensation table in the first storage element 150 (please refer to Figure 1 ).

[0065] For example, with reference Figure 3A and Figure 4 , Figure 4 4 is a schematic diagram of modifying the brightness compensation table according to an embodiment of the present disclosure. The first storage element 150 may pre-store a first brightness compensation table 401, wherein a plurality of first brightness compensation parameters of the first brightness compensation table 401 may be respectively used for Figure 3A In the first brightness compensation table 401, the first brightness compensation parameters corresponding to the plurality of light emitting elements 132 disposed in the frame of the first substrate 131 may be, for example, 1.1, the first brightness compensation parameters corresponding to the plurality of light emitting elements 132 disposed in the four corners of the first substrate 131 may be, for example, 2.2, and the first brightness compensation parameters corresponding to the plurality of light emitting elements 132 disposed in other positions of the first substrate 131 may be, for example, 1.0. The brightness compensation parameter may be used to indicate the ratio of the compensated brightness to the general brightness, but the present disclosure is not limited thereto. Figure 4 It is only used to represent a numerical example, and the numerical representation of the brightness compensation table of the present disclosure is not limited to this.

[0066] 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 parameters corresponding to the light-emitting element 132" to the light-emitting controller 112, so that the light-emitting controller 112 may generate a second brightness compensation table 402 according to the coordinate parameters corresponding to the light-emitting element 132", and multiply the multiple first brightness compensation parameters of the first brightness compensation table 401 by the corresponding multiple 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 defect may be greater than the second brightness compensation parameter of a normal light-emitting element that is not adjacent to the defective light-emitting element. Figure 4 As shown in the second brightness compensation table 402, the second brightness compensation parameter of the plurality of light emitting elements adjacent to the defective light emitting element may be 1.1, and the second brightness compensation parameter of the plurality of normal light emitting elements not adjacent to the defective light emitting element may be 1.0.

[0067] However, the numerical distribution of the second brightness compensation parameter of the second brightness compensation table of the present disclosure is not limited to Figure 4 In one embodiment, the values ​​of the second brightness compensation parameters in the second brightness compensation table may correspond to the defective light-emitting element as the center and decrease in sequence toward the periphery, and the disclosure is not limited in the manner in which the values ​​decrease. For example, in another embodiment, the values ​​of the second brightness compensation parameters in the second brightness compensation table may correspond to the defective light-emitting element having the same higher value for multiple parameters within a preset range.

[0068] In this regard, the light controller 112 may store the new first brightness compensation table 403 in the first storage element 150, and the first storage element 150 may replace the first brightness compensation table 401 with the new first brightness compensation table 403. Then, the timing controller 111 may read the first storage element 150 to store the new first brightness compensation table 403 in the second storage element 1111, and generate corresponding control signals according to the multiple new first brightness compensation parameters of the new first brightness compensation table 403, and output the corresponding control signals to the light driving element 120, so that the light driving element 120 can drive the multiple light emitting elements 132 of the light emitting module 130 according to the corresponding control signals. Figure 4 As shown in the new first brightness compensation table 403, since the brightness compensation parameter corresponding to the defective light-emitting element is 0, the light-emitting module 130 will not drive the defective light-emitting element, and perform brightness compensation by increasing the 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 improved.

[0069] In addition, the timing controller 111 of the present embodiment may also read the original first pixel compensation table stored in the first storage element 150 , and control the display driving element 160 to drive the display panel 170 according to the original first pixel compensation table.

[0070] However, in one embodiment, the light controller 112 may also output the coordinate parameters of the light emitting element corresponding to the defect to the timing controller 111. The timing controller 111 may have a corresponding operation algorithm, and read the first brightness compensation table 401 stored in the first storage element 150 during each restart of the electronic device 100, and store the first brightness compensation table 401 in the second storage element 1111. The timing controller 111 may modify the first brightness compensation table 401 according to the coordinate parameters of the light emitting element 132" corresponding to the defect to generate a new first brightness compensation table 403. The timing controller 111 may implement the above-mentioned Figure 4 The new first brightness compensation table 403 is generated in the described manner and stored in the second storage element 1111. In addition, the timing controller 111 or the light 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 storage element 150.

[0071] In addition, in another embodiment, the light controller 112 or the timing controller 111 may also generate a new first brightness compensation table 403 by directly modifying the first brightness compensation table 401 without establishing the second brightness compensation table 402 .

[0072] Figure 5 is a flow chart of an operating method of an electronic device according to an embodiment of the present disclosure. Figure 1 , Figure 3A , Figure 3B as well as Figure 5 In this embodiment, the electronic device 100 may perform the following steps S510 to S540 to effectively drive the light emitting module 130 and the display panel 170. In step S510, the detection element 140 may detect whether the plurality of light emitting elements 132 of the light emitting module 130 have defects. In step S520, in response to the detection element 140 detecting that at least one of the plurality of light emitting elements 132 has a defect, the detection element 140 may output an adjustment signal to the control module 110. Figure 3AAs shown, assuming that the detection element 140 detects that the light-emitting element 132" is a defective light-emitting element, the detection element 140 outputs a corresponding adjustment signal to the control module 110. In step S530, the control module 110 may generate a 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 a new first pixel compensation table according to the adjustment signal and the first pixel compensation table.

[0073] In the present embodiment, the detection element 140 may output a corresponding adjustment signal to the light controller 112 of the control module 110, wherein the adjustment signal may include coordinate parameters corresponding to the defective light emitting element 132". The light controller 112 may modify the first brightness compensation table and the first pixel compensation table according to the coordinate parameters corresponding to the defective light emitting element 132" to generate a new first brightness compensation table and a new first pixel compensation table, and store the new first brightness compensation table and the new first pixel compensation table in the first storage element 150.

[0074] The method for generating the new first brightness compensation table can be as described above. Figure 4 The description of the embodiment is not repeated here. Regarding the method of generating the new first pixel compensation table, for example, with reference to Figure 6 , Figure 6 6 is a schematic diagram of modifying a pixel compensation table according to an embodiment of the present disclosure. The first storage element 150 may pre-store a first pixel compensation table 601, wherein a plurality of first brightness compensation parameters of the first pixel compensation table 601 may be respectively used for Figure 3B In the first pixel compensation table 601, the first pixel compensation parameters corresponding to the plurality of pixel elements 172 may be, for example, 1. The pixel compensation parameter may be used to indicate the ratio of the aperture ratio (or pixel value, grayscale value) of the compensated pixel to the aperture ratio of a general pixel, but the present disclosure is not limited thereto. Figure 6 It is only used to represent a numerical example, and the numerical representation of the pixel compensation table of the present disclosure is not limited to this.

[0075] When the detection element 140 detects that the light-emitting element 132" is a defective light-emitting element, the detection element 140 can output the coordinate parameters corresponding to the light-emitting element 132" to the light-emitting controller 112, so that the light-emitting controller 112 can generate a second pixel compensation table 602 according to the coordinate parameters corresponding to the light-emitting element 132", and multiply the multiple first pixel compensation parameters of the first pixel compensation table 601 by the corresponding multiple second pixel compensation parameters of the second pixel compensation table 602 one-to-one to generate a new first pixel compensation table 603 with multiple new first pixel compensation parameters. In the second pixel compensation table 602, the multiple second pixel compensation parameters of the multiple pixel elements 172" corresponding to the defective light-emitting element 132" are higher than other second pixel compensation parameters corresponding to normal light-emitting elements.

[0076] like Figure 3B and Figure 6 As shown in the second pixel compensation table 602, the second pixel compensation parameter of the pixel element at the center position of the multiple pixel elements 172" corresponding to the light-emitting element 132" may be 1.5, the second pixel compensation parameters of other pixel elements of the multiple pixel elements 172" corresponding to the light-emitting element 132" may be 1.1, and other second pixel compensation parameters corresponding to normal light-emitting elements may be 1.0.

[0077] However, the numerical distribution of the second pixel compensation parameter of the second pixel compensation table of the present disclosure is not limited to Figure 6 In one embodiment, the values ​​of the second pixel compensation parameters in the second pixel compensation table may correspond to the defective light emitting element as the center and decrease in sequence toward the periphery, and the disclosure is not limited in the manner in which the values ​​decrease. For example, in another embodiment, the values ​​of the second pixel compensation parameters in the second pixel compensation table may correspond to the same higher values ​​for multiple parameters within a preset range of the defective light emitting element.

[0078] In this regard, the light emitting controller 112 may store the new first pixel compensation table 603 in the first storage element 150, and the first storage element 150 may replace the first pixel compensation table 601 with the new first pixel compensation table 603. Then, the timing controller 111 may read the first storage element 150 to store the new first pixel compensation table 603 in the second storage element 1111, and generate corresponding display data according to a plurality of 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 can drive a plurality of pixel elements 172 of the display panel 170 according to the corresponding display data. Figure 6As shown in the new first pixel compensation table 603, since the values ​​of the multiple pixel compensation parameters of the multiple pixel elements corresponding to the defective light emitting element are higher than other pixel compensation parameters, the multiple pixel elements of the display panel 170 corresponding to the position with the light emitting defect can be correspondingly adjusted to have a higher aperture ratio. In this way, the problem of uneven display brightness of the display screen caused by the defective light emitting element can be effectively improved.

[0079] However, in one embodiment, the light controller 112 may also output the coordinate parameters of the defective light emitting element to the timing controller 111. The timing controller 111 may have a corresponding operation algorithm, and read the first pixel compensation table 601 stored in the first storage element 150 during each restart of the electronic device 100, and store the first pixel compensation table 601 in the second storage element 1111. The timing controller 111 may modify the first pixel compensation table 601 according to the coordinate parameters of the defective light emitting element 132" to generate a new first pixel compensation table 603. The timing controller 111 may implement the above-mentioned Figure 6 The new first pixel compensation table 603 is generated in the described manner and stored in the second storage element 1111. Furthermore, the timing controller 111 or the light emitting 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 storage element 150.

[0080] In addition, in another embodiment, the light emitting controller 112 or the timing controller 111 may also generate a new first pixel compensation table 603 by directly modifying the first pixel compensation table 601 without establishing the second pixel compensation table 602 .

[0081] Figure 7 is a flow chart of an operating method of an electronic device according to an embodiment of the present disclosure. Figure 1 , Figure 3A , Figure 3B as well as Figure 7 In this embodiment, the electronic device 100 may perform the following steps S710 to S730 to effectively drive the display panel 170. In step S710, the detection element 140 may detect whether the plurality of light emitting elements 132 of the light emitting module 130 have defects. In step S720, in response to the detection element 140 detecting that at least one of the plurality of light emitting elements 132 has a defect, the detection element 140 may output an adjustment signal to the control module 110. Figure 3AAs shown, assuming that the detection element 140 detects that the light emitting element 132" is a defective light emitting element, the detection element 140 outputs a corresponding adjustment signal to the control module 110. In step S730, the control module 110 can generate a new first pixel compensation table according to the adjustment signal and the first pixel compensation table.

[0082] In this embodiment, the detection element 140 can output a corresponding adjustment signal to the light controller 112 of the control module 110, wherein the adjustment signal may include coordinate parameters corresponding to the defective light-emitting element 132". The light controller 112 can modify the first pixel compensation table according to the coordinate parameters corresponding to the defective light-emitting element 132" to generate a new first pixel compensation table, and store the new first pixel compensation table in the first storage element 150.

[0083] The method for generating the new first pixel compensation table can be as described above. Figure 6 The description of the embodiments is not repeated here. Figure 6 As shown in the new first pixel compensation table 603, since the values ​​of the multiple pixel compensation parameters of the multiple pixel elements corresponding to the defective light emitting element are higher than other pixel compensation parameters, the multiple pixel elements of the display panel 170 corresponding to the position with the light emitting defect can be correspondingly adjusted to have a higher aperture ratio. In this way, the problem of uneven display brightness of the display screen caused by the defective light emitting element can be effectively improved.

[0084] In addition, the timing controller 111 of the present embodiment may also read the original first brightness compensation table stored in the first storage element 150 , and control the light driving element 120 to drive the light emitting module 130 according to the original first brightness compensation table.

In step S810, the detection element 140 detects a defective light-emitting element and confirms the current light-emitting area in the light-emitting module 130. In step S820, the detection element 140 may output an adjustment signal to the control module 110 to notify the control module 110 to perform compensation. For the method of compensation by the control module 110, please refer to the above Figures 2 to 7The description of the embodiments will not be elaborated here. In step S830, the detection element 140 can detect the next light-emitting area in the light-emitting module 130. In step S840, the detection element 140 can determine whether a defective light-emitting element is detected. If so, step S810 is executed. If not, step S850 is executed. In step S850, the detection element 140 can determine whether there are any light-emitting areas that have not been detected. If so, step S830 is executed. If not, step S860 is executed to end the detection.

In this regard, since the frame position corresponding to the active area 1010 of the display panel may have insufficient brightness if only the plurality of light emitting elements 1002 corresponding to the active area 1010 provide backlight, the light emitting module 1000 of this embodiment further provides a plurality of light emitting elements 1003 in the peripheral area outside the active area 1010 to effectively compensate for the brightness of the frame position corresponding to the active area 1010. It should be noted that the “correspondence” described here may mean that the projection of one element or / and region in the normal direction of the electronic device may overlap with another element or / and region. For example, the plurality of light-emitting elements 1002 may correspond to the active area of ​​the display panel. In other words, the projection of the plurality of light-emitting elements 1002 in the normal direction of the electronic device may overlap with another element or / and region.
