[0055] In order to make the description of the following embodiments clear and concise, a brief introduction of a display screen is first given:

[0056] Existing display screens use relevant testing instruments or manual testing of the internal display circuit only when a fault occurs, and then determine the cause of the fault to facilitate subsequent maintenance by the user. However, this method can only detect the fault when it is determined that a fault exists, which will result in poor display effects and require users to subjectively determine the fault, resulting in low functionality of the entire fault detection.

[0057] The present solution proposes a display screen, including a display screen control circuit and a display detection circuit, wherein the display screen control circuit includes a plurality of sub-pixel area groups in a first direction and a display control module, wherein the display control module is connected to a first end of each of the sub-pixel area groups, and the display detection circuit includes: a detection selection module, wherein a first end of the detection selection module is connected to the display control module, and a second end of the detection selection module is connected to an external wake-up power supply, wherein the display control module is used to obtain input display parameter information, determine a display detection instruction according to the display parameter information, and control the detection selection module to be in a detection selection state based on the display detection instruction; and a plurality of light-emitting detection modules, wherein an input end of one of the light-emitting detection modules is connected to a second end of a different sub-pixel area group, an output end of the light-emitting detection module is connected to a third end of the detection selection module, and a power supply end of the light-emitting detection module is connected to a fourth end of the detection selection module, wherein the light-emitting detection module is used to obtain display state information of the sub-pixel area group in the detection selection state, and the display control module is further used to determine a display control instruction according to the display parameter information, and determine a display screen state according to the display control instruction and the display state information, and determine a detection result of the display screen based on the display screen state. This display screen, through the composition and connection relationship of the display screen control circuit and the display detection circuit, can obtain the display status information of the sub-pixel area group in the detection selection state based on the light emitting detection module (display parameter information determines the display detection instruction, and controls the detection selection module to be in the detection selection state based on the display detection instruction). Finally, the display control instruction can be determined according to the display parameter information in the display control module, and the display screen state can be determined according to the display control instruction and the display status information, so as to avoid the phenomenon in the prior art that whether the thin film transistor is normally emitting light and displaying cannot be detected. This display screen can determine the display screen state of the display screen based on the display screen control circuit and the display detection circuit and the corresponding control detection method, thereby improving the functionality of the display screen.

[0058] In one embodiment of the present invention, Figure 1 As shown, Figure 1 1 is a schematic diagram of a structural framework of a display screen of the present application, wherein the display screen includes a display screen control circuit 100 and a display detection circuit 200, wherein the display screen control circuit 100 includes a plurality of sub-pixel area groups 110 in a first direction and a display control module 120, wherein the display control module 120 is connected to a first end of each of the sub-pixel area groups 110, and the display detection circuit 200 includes:

[0059] A detection selection module 210, wherein a first end of the detection selection module 210 is connected to the display control module 120, and a second end of the detection selection module 210 is connected to an external wake-up power supply 300, wherein the display control module 120 is used to obtain input display parameter information, determine a display detection instruction according to the display parameter information, and control the detection selection module 210 to be in a detection selection state based on the display detection instruction;

[0060] A plurality of light-emitting detection modules 220, wherein an input end of one of the light-emitting detection modules 220 is connected to a second end of a different sub-pixel area group 110, an output end of the light-emitting detection module 220 is connected to a third end of the detection selection module 210, and a power supply end of the light-emitting detection module 220 is connected to a fourth end of the detection selection module 210, wherein the light-emitting detection module 220 is used to obtain display state information of the sub-pixel area group 110 in a detection selection state;

[0061] The display control module 120 is further configured to determine a display control instruction according to the display parameter information, and determine a display screen state according to the display control instruction and the display state information, so as to determine a detection result of the display screen based on the display screen state.

[0062] In this embodiment, the display screen includes a display screen control circuit 100 and a display detection circuit 200. The display screen control circuit 100 refers to a circuit that controls the display screen to display. The display mode at least includes a normal display and a detection display mode. The display screen control circuit 100 includes a plurality of sub-pixel area groups 110 in a first direction and a display control module 120. The display control module 120 is connected to the first end of each sub-pixel area group 110, and can further control each sub-pixel area group 110 to display. The display control module 120 can be directly a control chip, such as a system-level control chip, a microcontroller chip, etc., and can be controlled based on an internal display control program. At this time, the display control module 120 will receive the input display parameter information, that is, the parameters that need to control how the display screen displays. For example, in order to display picture A, the odd-numbered sub-pixel area group needs to be displayed, that is, the display parameter information refers to the parameters that control the odd-numbered sub-pixel area group to charge and display, because the display detection circuit 200 also includes a detection selection module 210 and multiple light-emitting detection modules 220, wherein the first end of the detection selection module 210 is connected to the display control module 120, and the second end of the detection selection module 210 is connected to the external wake-up power supply 300, and then the display control module 120 can determine the display detection instruction according to the display parameter information, and then control the detection selection module 210 to be in the detection selection state based on the display detection instruction. The display detection instruction refers to the instruction on which sub-pixel area group 110 to detect, and the detection selection state refers to the state of controlling the light-emitting detection module 220 of that group to perform fault detection. For example, if there are two sub-pixel area groups 110, E1 and E2, and if the display parameter information is to control E1 for display, it can be determined that the display detection instruction will detect E2, and the detection selection module 210 turns on (including power supply wake-up and connecting with the display control module 120 for communication) the light detection module 220 connected to E2, and at the same time determines the display control instruction based on the display parameter information, that is, the instruction on how to display E2. At this time, it is necessary to not affect the normal display of E1 and can be detected. At this time, the light detection module 220 connected to E2 will be used to obtain the display status information of E2, that is, the light information of E2, and then the display screen status of E2 will be determined based on the display status information and the display control instruction, that is, the display status of E2. At this time, when the entire display screen is working normally, the status of the abnormal sub-pixel area group 110 can be determined, thereby ensuring the accuracy of subsequent control of the abnormal sub-pixel area group 110, and at the same time improving the functionality of the display screen.

[0063] Further, based on the first embodiment of the above-mentioned display screen, a second embodiment of the display screen of the present application is proposed, referring to Figure 2 , Figure 21 is a connection diagram of a light emitting detection module in the display screen of the present application. The second end of the sub-pixel area group 110 includes a display element 10, and the light emitting detection module 220 includes:

[0064] A power detection sensor 221 is provided at the input end of the display element 10, and an output end of the power detection sensor 221 is connected to the detection selection module 210, wherein the power detection sensor 221 is used to use the power information flowing to the display element as display status information.

[0065] In one embodiment, the sub-pixel group 110 includes a display area, the second end of the sub-pixel group 110 is a non-display area 112 adjacent to the display area, and the light emitting detection module 220 includes:

[0066] The brightness detection sensor 222 is attached to the display back of the non-display area 112, and the output end of the brightness detection sensor 222 is connected to the detection selection module 210, wherein the brightness detection sensor 222 uses the brightness information collected by the non-display area as display status information.

[0067] In this embodiment, on the one hand, the light-emitting detection module 220 may include a power detection sensor 221, and then detect the power output to the display element 10 to determine whether the entire sub-pixel area group 110 is normally outputting power to control the display element 10 to display normally, and then determine whether the sub-pixel area group 110 can work normally. On the other hand, the light-emitting detection module 220 may also include a brightness detection sensor 222, and then directly determine whether the display is normal by detecting the light-emitting brightness of the sub-pixel area group 110. It is worth noting that the sub-pixel area group 110 includes a display area and an adjacent non-display area 112. At this time, the brightness detection sensor 222 can be attached to the display back side of the non-display area 112, that is, on the back side of the non-display area 112 (it can also be set on the front side), so as not to affect the normal display of the entire sub-pixel area group 110. At this time, the power detection sensor 221 will be used to use the power information (current and other information) flowing to the display element as display status information, and then determine whether the power information matches the power output of the display control instruction. The brightness information collected in the non-display area can also be used as display status information, that is, the luminous brightness of the display element 10, so as to determine whether the sub-pixel area group 110 of the luminous detection is displayed normally based on the brightness and power, and then determine the fault condition of the sub-pixel area group 110. It is worth noting that whether the power detection sensor 221 or the brightness detection sensor 222 is used, each sub-pixel area 111 in the sub-pixel area group 110 is detected, and then the state of each sub-pixel area 111 is determined, so as to facilitate display processing for each sub-pixel area 111, so as to determine the sub-pixel area 111 with a fault, and then through subsequent different processing methods to ensure the display effect of the entire display screen.

[0068] Further, based on the first embodiment and / or the second embodiment of the display screen described above, a third embodiment of the display screen of the present application is proposed, referring to Figure 3 , Figure 3 1 is a connection diagram of the detection selection module in the display screen of the present application. The display control module 120 includes a first control terminal 121, a second control terminal 123 and a detection information terminal 122. The detection selection module 210 includes:

[0069] A detection selector 211, wherein a control end of the detection selector 211 is connected to the first control end 121, an input end of the detection selector 211 is connected to different input ends of the light emitting detection module 220, and an output end of the detection selector 211 is connected to the detection information end 122;

[0070] The wake-up selector 212 has a control end connected to the second control end 123, an input end connected to the external wake-up power supply 300, and an output end of the wake-up selector 212 connected to different power supply ends of the luminescence detection module 220.

[0071] In this embodiment, the detection selection module 210 includes a selection for wake-up power supply and a selector for establishing a connection with the display control module 120. At this time, by determining the display detection instruction, it is determined which sub-pixel area group 110 needs to be detected. At this time, the line between the power supply end 220 of the luminous detection module corresponding to the sub-pixel area group 110 and the external wake-up power supply 300 will be connected through the wake-up selector 212, thereby realizing power supply to the luminous detection module 220 corresponding to the sub-pixel area group 110. It is worth noting that the wake-up selector 212 can be a single-input multi-output selector, thereby realizing that when multiple sub-pixel area groups 110 are detected, the luminous detection modules 220 corresponding to the multiple sub-pixel area groups 110 can be powered on and woken up at the same time, thereby ensuring the efficiency of detection. The selector in the detection selection module 210 that establishes a connection with the display control module 120 is the detection selector 211, which determines which sub-pixel area group 110 needs to be detected. At this time, the detection selector 211 will be connected to send the information collected by the light-emitting detection module 220 corresponding to the sub-pixel area group 110 to the detection information terminal 122, wherein there can be multiple detection information terminals 122, that is, there is a uniquely connected detection information terminal 122 for each light-emitting detection module 220, so that the information transmitted by each light-emitting detection module 220 can be clearly and conveniently processed (that is, the detection selector 211 is a multi-input and multi-output selector at this time). Of course, one detection information terminal 122 can also be used to obtain information transmitted by multiple light-emitting detection modules 220, that is, the detection selector 211 is a multi-input and single-output selector at this time, which can selectively power the light-emitting detection module 220 that needs to be detected and transmit information, thereby ensuring the high efficiency of the use of the entire display screen, and at the same time, combined with normal display work, the functionality of the entire display screen can be guaranteed.

[0072] Further, based on the first embodiment, the second embodiment and / or the third embodiment of the above-mentioned display screen, a fourth embodiment of the display screen of the present application is proposed, referring to Figure 4 , Figure 4 1 is a connection diagram of a sub-pixel area group in the display screen of the present application, the display control module 120 includes a display control terminal 124, the sub-pixel area group 110 includes a plurality of sub-pixel areas 111, wherein the sub-pixel areas 111 are connected in series horizontally or vertically to form the sub-pixel area group 110, and the sub-pixel areas 111 include:

[0073] A charging control switch tube Q, wherein the control end of the charging control switch tube Q is connected to the display control end 124, and the first end of the charging control switch tube Q is connected to the data input end D;

[0074] A charging capacitor C, wherein a first end of the charging capacitor C is connected to a second end of the charging control switch tube Q;

[0075] The display element 10 has an input terminal connected to the second terminal of the charging capacitor C.

[0076] Furthermore, the display control module 120 includes a third control terminal 125, and the display screen control circuit 100 also includes a pixel charging module, wherein one pixel charging module is connected to one sub-pixel area group 110, and the pixel charging module includes:

[0077] A conduction selector 400, wherein the control end of the conduction selector 400 is connected to the third control end 125, the first output end of the conduction selector 400 is connected to the first end of the first charging control switch tube in the sub-pixel area group 110, the second output end of the conduction selector 400 is connected to the first end of the second charging control switch tube in the sub-pixel area group 110, and the input end of the conduction selector 400 is connected to the data input end D, wherein the first charging control switch tube includes the charging control switch tube Q of the last sub-pixel area 111 in the sub-pixel area group 110, and the second charging control switch tube includes the charging control switch tube Q of the first sub-pixel area 111 in the sub-pixel area group 110.

[0078] In this embodiment, the display control module 120 includes a display control terminal 124, and the sub-pixel area group 110 includes a plurality of sub-pixel areas 111, wherein the sub-pixel areas 111 are connected in series horizontally or vertically to form the sub-pixel area group 110 (the present application takes the horizontal series connection as an example for explanation), and the sub-pixel area 111 includes a charging control switch tube Q, a charging capacitor C, and a display element 10 (such as a light-emitting device). At this time, by turning on the charging control switch tube Q, the electric quantity of the data input terminal D is input to the charging capacitor C, and when display is required, the electric quantity in the charging capacitor C drives the display element 10 to complete the display of each sub-pixel area 111, and then the display control terminal 124 can be used to control different sub-pixel areas 111 to display at different brightness. At this time, the sub-pixel area 111 to be detected will be controlled to display based on the display control terminal 124, and then the display condition of the sub-pixel area 111 will be detected to determine whether it matches the normal display condition. If it matches, it is determined that the sub-pixel area 111 is normal, otherwise it is determined that the sub-pixel area 111 is abnormal. At the same time, in order to avoid display abnormalities caused by disconnection, the display screen control circuit 100 also includes a pixel charging module, wherein one of the pixel charging modules is connected to one of the sub-pixel area groups 110, and the pixel charging module includes a conduction selector 400, and then the data input terminal D is controlled by the conduction selector 400 to start charging by the charging control switch tube Q of the last sub-pixel area 111 in the sub-pixel area group 110, or by the charging control switch tube Q of the first sub-pixel area 111 in the sub-pixel area group 110, so as to avoid display abnormalities caused by disconnection. For example, when it is determined that the charging control switch tube Q of the first sub-pixel area 111 in the sub-pixel area group 110 starts charging, and the last sub-pixel area 111 does not emit light, the charging control switch tube Q of the first sub-pixel area 111 in the sub-pixel area group 110 will start charging (determine that the last sub-pixel area 111 emits light), and it will be determined as a disconnection and the user will be prompted at the same time, but during this period, the display control will still be performed in a bidirectional charging manner, thereby ensuring the display effect when a fault occurs and the self-fault backup display function of the display.

[0079] Further, based on the above-mentioned display screen embodiment, a first embodiment of the display control method of the present invention is proposed, referring to Figure 5 , Figure 5 1 is a flow chart of a first embodiment of the display control method of the present application applied to a display screen, wherein the steps of the display control method include:

[0080] Step S10, obtaining input display parameter information, and determining a display detection instruction according to the display parameter information, wherein the display detection instruction is used to control the detection selection module to be in a detection selection state;

[0081] Step S20, determining a display control instruction according to the display parameter information, and determining a display screen state according to the display control instruction and the display status information, so as to determine a detection result of the display screen based on the display screen state, wherein the display status information is the display state of the sub-pixel area group obtained by the luminous detection module in the detection selection state.

[0082] In this embodiment, when it is necessary to control the display screen to display, the display detection instruction will be determined by the acquired display parameter information, wherein the display detection instruction is used to control the detection selection module to be in the detection selection state, the display parameter information refers to the parameters for controlling the light emission of the sub-pixel area group on the display screen, such as light emission, no light emission, red light, etc., the display detection instruction refers to the instruction for determining the non-luminous sub-pixel area group based on the display parameter information, and then controlling the non-luminous sub-pixel area group to perform a specific display for detection (i.e., controlling the detection selection module to select which light emission detection module to power and communicate), and the detection selection state refers to the state of selecting the light emission detection module corresponding to the sub-pixel area group to be detected to wake up and communicate with the display control module. At the same time, the display control instruction will be determined based on the display parameter information, that is, the instruction for controlling the non-luminous sub-pixel area group is determined, because the sub-pixel group near the non-luminous sub-pixel area group may be strong light, so it can be controlled by weak light, but if the sub-pixel group near the non-luminous sub-pixel area group is weak light, in order not to affect the nearby sub-pixel group, it is necessary to use other instructions for control. At this time, the state of the display screen can be determined based on the display control instructions and display status information, that is, the state of the non-luminous sub-pixel area group on the display screen, specifically the state of each sub-pixel area in the non-luminous sub-pixel area group, and then the detection result of the display screen can be used to facilitate the subsequent control of the display screen display, and then each non-luminous state can be detected in the normal display frame to facilitate subsequent display control, thereby improving the functionality and display effect of the display screen.

[0083] Further, based on the first embodiment of the above-mentioned display control method, a second embodiment of the display control method of the present application is proposed, wherein the display parameter information includes a first display parameter for color light display and a second display parameter for dim light display, and the step of determining the display control instruction according to the display parameter information includes:

[0084] Step S21, determining a first sub-pixel area group corresponding to the first display parameter in the sub-pixel area group, and determining a second sub-pixel area group corresponding to the second display parameter in the sub-pixel area group;

[0085] Step S22, for each of the second sub-pixel area groups, determining a third sub-pixel area group in the first sub-pixel area group, wherein the third sub-pixel area group includes a first sub-pixel area group adjacent to the second sub-pixel area group;

[0086] Step S23, when the first display parameter of the third sub-pixel area group matches the preset parameter threshold, using the preset first low light control instruction as the display control instruction;

[0087] Step S24: when the first display parameter of the third sub-pixel area group does not match the preset parameter threshold, using the preset second low light control instruction as the display control instruction.

[0088] In this embodiment, the display parameter information includes a first display parameter for color light display and a second display parameter for dim light display, that is, the parameters for controlling the sub-pixel area group to display include color light display and dim light display, that is, color light display refers to a display mode that can emit light normally, and dim light display refers to a display mode that emits faint light or no light, which generally does not affect the overall light. By determining the first sub-pixel area group corresponding to the first display parameter in the sub-pixel area group, and determining the second sub-pixel area group corresponding to the sub-pixel area group, that is, determining the first sub-pixel area group for color light display and the second sub-pixel area group for dim light display in all sub-pixel area groups, and then for each second sub-pixel area group, a third sub-pixel area group is determined in the first sub-pixel area group, wherein the third sub-pixel area group includes the first sub-pixel area group adjacent to the second sub-pixel area group, that is, determining the first sub-pixel area group adjacent to each second sub-pixel area group as the third sub-pixel area group, at this time, when the first display parameter of the third sub-pixel area group matches the preset parameter threshold, the preset first dim light control instruction will be directly used as the display control instruction. Command, wherein the preset parameter threshold refers to the display parameter defined by the user, and the preset parameter threshold is M. At this time, there is a low-light source of M1 next to M, but the low-light source will not affect the display of M, then it is determined that the two parameters match, otherwise, it is determined that the two parameters do not match, the first low-light control instruction refers to the control instruction of the low-light, generally a low-light instruction that does not affect the display of the third sub-pixel area group, such as a tiny white light; when the two parameters do not match, the second low-light control instruction will be determined as the display control instruction, and the second low-light control instruction refers to the low-light instruction that controls the matching of the adjacent light emission, and the tiny white light similar to the adjacent third sub-pixel area group, and thus will not affect the normal display of the entire display screen, so as to ensure the display effect when the display screen is working normally. The step of determining the third sub-pixel area group in the first sub-pixel area group for each of the second sub-pixel area groups includes:

[0089] Step S221, for each of the second sub-pixel area groups, detecting whether there is a first adjacent sub-pixel area group adjacent to the second sub-pixel area group in the first sub-pixel area group;

[0090] Step S222, when there is a first adjacent sub-pixel group adjacent to the second sub-pixel group in the first sub-pixel group, use the first adjacent sub-pixel group as a third sub-pixel group;

[0091] Step S223, when there is no first adjacent sub-pixel group adjacent to the second sub-pixel group in the first sub-pixel group, all the adjacent second sub-pixel groups are taken as the second sub-pixel group as a whole, and based on the second sub-pixel group as a whole, the step of detecting whether there is a first adjacent sub-pixel group adjacent to the second sub-pixel group in the first sub-pixel group is performed for each second sub-pixel group.

[0092] In this embodiment, when determining the third sub-pixel block group, it is first detected whether there is a first adjacent sub-pixel group adjacent to the second sub-pixel block group in the first sub-pixel block group, and then when the first adjacent sub-pixel group exists, the first adjacent sub-pixel group is used as the third sub-pixel block group. Otherwise, if the first adjacent sub-pixel group does not exist, it is determined that there are second sub-pixel blocks with multiple rows of dark light display, and then all the second sub-pixel blocks are used as the second sub-pixel block group as a whole. At the same time, based on the second sub-pixel block group as a whole, the step of detecting whether there is a first adjacent sub-pixel group adjacent to the second sub-pixel block group in the first sub-pixel group is performed for each of the second sub-pixel blocks. It is worth noting that at this time there will be no control of the first low-light control instruction and the second low-light control instruction. If the first display parameter of the third sub-pixel area group matches the preset parameter threshold, then all the second sub-pixel area groups are the first low-light control instruction to ensure that it will not affect the overall display. If it does not match, the adjacent third sub-pixel area group can be the second low-light control instruction, and the others are the first low-light control instruction, thereby avoiding the second low-light control instruction from controlling for too long, resulting in obvious color change in the display, thereby ensuring the display effect of the entire display screen.

[0093] Further, based on the first embodiment and / or the first embodiment of the above-mentioned display control method, a third embodiment of the display control method of the present application is proposed, wherein the step of determining the display screen state according to the display control instruction and the display state information includes:

[0094] Step S25, determining the display state data of all target sub-pixel area groups in the display state information, and for each of the display state data, determining a target display control instruction corresponding to the display state information in the display control instruction, wherein the target display control instruction includes a preset first shimmer control instruction and a preset second shimmer control instruction;

[0095] Step S26, when the target display control instruction is the first low-light control instruction, detecting whether the display state data matches the preset low-light threshold data, and when the display state data matches the preset low-light threshold data, determining that the display screen state of the target sub-pixel area group is a normal display; when the display state data does not match the preset low-light threshold data, determining that the display screen state of the target sub-pixel area group is an abnormal display;

[0096] Step S27, when the target display control instruction is the second low-light control instruction, the adjacent display data corresponding to the target sub-pixel area group is obtained, and it is detected whether the display status data matches the adjacent display data. When the display status data matches the adjacent display data, it is determined that the display screen state of the target sub-pixel area group is normal display; when the display status data does not match the adjacent display data, it is determined that the display screen state of the target sub-pixel area group is abnormal display.

[0097] In the present embodiment, when determining the display screen state, the display status data of all target sub-pixel area groups in the display status information are determined, and then for each of the display status data (i.e., each target sub-pixel area group is processed), the target display control instruction corresponding to the display status information is determined in the display control instruction, wherein the target display control instruction includes a preset first glimmer control instruction and a preset second glimmer control instruction, and then when the target display control instruction is the first glimmer control instruction, it is detected whether the display status data matches the preset glimmer threshold data, the glimmer threshold data refers to the display data that should be displayed under the control of the user-defined first glimmer control instruction, and the data is expressed as power or luminous brightness, and the display screen state of the target sub-pixel area group is determined to be normal display; when the display status data does not match the preset glimmer threshold data, it is determined that the display screen state of the target sub-pixel area group is abnormal display. It is worth noting that at this time, the detection of the target sub-pixel area group is performed on each sub-pixel area in the target sub-pixel area group, and the detection result determined is that the display screen state of the target sub-pixel area group is normal display, or the display screen state of some sub-pixel areas in the target sub-pixel area group is abnormal display. When the target display control instruction is the second low-light control instruction, the adjacent display data corresponding to the target sub-pixel area group is obtained, and the adjacent display data refers to the display data of the adjacent sub-pixel area group, which can generally be the display data for each sub-pixel area of ​​the adjacent sub-pixel area group, and then detects whether the display status data matches the adjacent display data, and when the display status data matches the adjacent display data, determines that the display screen state of the target sub-pixel area group is normal display, otherwise determines that the display screen state of the target sub-pixel area group is abnormal display. It is worth noting that at this time, the detection of the target sub-pixel area group is performed on each sub-pixel area in the target sub-pixel area group, and then determines that the detection result is that the display screen state of the target sub-pixel area group is normal display, or the display screen state of some sub-pixel areas in the target sub-pixel area group is abnormal display, and then it can be accurately determined that some sub-pixel areas have display abnormalities, and then timely alarm to prompt the user and define the next display control method to ensure the display effect.

[0098] In one embodiment, after the step of determining the display screen state according to the display control instruction and the display state information, the following steps are included:

[0099] Step S30, when the display screen state of the target sub-pixel area group is abnormal display, determining all target sub-pixel areas with abnormal display in the target sub-pixel area group;

[0100] Step S40, when there is only one target sub-pixel area, control the target sub-pixel area to perform luminous display based on a preset reverse charging instruction, and when the display status data under the luminous display matches the preset low light threshold data, determine that the display screen state of the sub-pixel area is normal display.

[0101] In this embodiment, when it is determined to be an abnormal display, all target sub-pixel areas with abnormal display in the target sub-pixel area group will be determined. The target sub-pixel area refers to the sub-pixel area found to be abnormally displayed in the target sub-pixel area group. Then, when the target sub-pixel area is one or the tail (the last position along the forward charging) is continuous, the target sub-pixel area is controlled to display light based on the preset reverse charging instruction, and when the display state data under the light display matches the preset dim light threshold data, the display screen state of the sub-pixel area is determined to be normal display. The reverse charging instruction refers to an instruction to start charging based on the last sub-pixel area. Under normal circumstances, charging is generally started based on the first sub-pixel area. At the same time, a bidirectional charging method is used during the next charging control. It is worth enabling that, if it is not the above situation, an alarm is issued, and when the next display parameter information comes, it is determined whether the target sub-pixel area needs to be used. When the target sub-pixel area needs to be used, the display parameter information corresponding to the target sub-pixel area is combined to control the adjacent sub-pixel area of ​​the target sub-pixel area to display, thereby compensating for the defect that the target sub-pixel area cannot display, so as to ensure the display effect.
