[0043] Please refer to Figure 1 The display panel brightness compensation method of an embodiment of the present application is used to determine whether the display panel is compensated for brightness at a brightness compensation station. The display panel includes a control panel, and the control panel stores a header file. The display panel brightness compensation method includes the following steps: adding a brightness compensation indication bit in the header file; determining whether the display panel is compensated for brightness at the brightness compensation station based on a judgment byte shown by the brightness compensation indication bit; and skipping the brightness compensation station in response to the display panel not being compensated for brightness at the brightness compensation station.

[0044] In an embodiment of the present application, a brightness compensation indication bit is added in the header file. The value of the judgment byte of the brightness compensation indication bit is used to determine whether the display panel needs to be compensated for brightness. Specifically, different values of the judgment byte correspond to different determination results.

[0045] The present application adds a brightness compensation judgment indication bit in the header file of the control panel. The value of the judgment byte of the judgment indication bit is used to determine whether the display panel needs to be compensated for brightness. The configuration parameters are automatically modified to realize automatic skipping of the brightness compensation of the display panel, avoid the error-prone problem of manual modification of the parameters of the production line machine, and reduce labor costs.

[0046] It should be noted that the brightness compensation indication bit is added to the header file of the control panel of the display panel after factory debugging. The judgment byte can be a bit in specific embodiments.

[0047] Specifically, after the in-factory debugging, it is judged whether the display panel is suitable for the brightness compensation according to whether the specific display brightness contrast and other information of the display panel has reached the expected demand, and according to the display panel model specification and other information. The result is written as a judgment byte in the brightness compensation indication bit, so as to facilitate the judgment after reaching the brightness compensation station.

[0048] It should be further pointed out that the present application mainly aims at whether the display panel needs to be subjected to DGC Gamma correction on the production line machine, and corresponding actions are performed according to different judgment results.

[0049] In some embodiments, the judgment byte is a first value and a second value; in response to the judgment byte being the first value, the display panel is subjected to brightness compensation; and in response to the judgment byte being the second value, the display panel is not subjected to brightness compensation.

[0050] In the present embodiment, the brightness compensation indication bit is a hexadecimal bit. Meanwhile, the result of whether the display panel is subjected to brightness compensation only has two kinds, one is compensation, and the other is no compensation, so that the judgment byte corresponding to the brightness compensation indication bit has two, which can meet the judgment indication demand and is convenient to distinguish. Correspondingly, when the judgment byte of the brightness compensation indication bit is the first value, it indicates that the display panel is subjected to brightness compensation; and when the judgment byte of the brightness compensation indication bit is the second value, it indicates that the display panel is not subjected to brightness compensation. This kind of indication and judgment mode is simple and convenient, and easy to read.

[0051] In some embodiments, in response to the judgment byte being the second value, the display panel is not subjected to brightness compensation, including: in response to the judgment byte being the second value, modifying the configuration parameter, skipping the brightness compensation station, and proceeding to the next process.

[0052] In the present embodiment, when the judgment byte of the brightness compensation indication bit displays the second value, it indicates that the display panel is not suitable for brightness compensation at the brightness compensation station. At this time, the production line machine automatically modifies the machine configuration parameter, so that the display panel is not subjected to brightness compensation, and the display panel skips the brightness compensation station and enters the next process through the modification of the configuration parameter.

[0053] In some embodiments, the configuration parameter includes a parameter related to brightness compensation in a parameter control panel of the production line machine.

[0054] Specifically, the configuration parameter referred to in the present embodiment can be the gray scale brightness information of the sampling point, the gamma reference voltage, and the gamma value and other related information. Through the adjustment of the brightness compensation related parameters, the brightness compensation of the display panel of this model is realized, the manual modification of the machine parameter is replaced, and the risk of manual modification is effectively avoided.

[0055] For example, the brightness compensation of the embodiments of the present application can be the correction of the DGC algorithm. Therefore, the correction of the DGC algorithm can be skipped by adjusting the gamma value. The DGC algorithm usually uses gamma correction to adjust the brightness response curve, and the contrast of the image can be changed by adjusting the gamma value. If the DGC algorithm is to be skipped, the gamma value can be adjusted to be linear (usually 1.0) to keep the brightness response of the image linear. In this way, the correction of the DGC algorithm is achieved.

[0056] It should be noted that which parameters can be modified to skip the correction of the DGC algorithm depends on the specific device and system, and different devices can have different parameters to adjust.

[0057] In some embodiments, before determining whether to perform brightness compensation on the display panel, the following steps are further included: powering on the control board; determining whether the control board is consistent with the control board of the display panel after factory debugging is completed; and in response to the control board being consistent with the control board of the display panel after factory debugging is completed, reading the judgment byte of the brightness compensation indication bit.

[0058] Since the brightness compensation indication bit is added in advance in the header file of the control board of the display panel, all display panels can be read by the judgment byte of the brightness indication bit. In addition, the display panel usually includes a control board and a display screen, which are generally separate and assembled together later. Therefore, during the production process, there may be a situation of incorrectly assembling the control board. Therefore, before determining whether to perform brightness compensation on the display panel, it is also necessary to determine whether the control board of the display panel is correct, and then determine whether the display panel needs to be read by the subsequent brightness indication bit judgment byte and whether the brightness compensation needs to be determined. This is equivalent to a preliminary selection, thereby improving the work efficiency of brightness compensation. That is, if the control board of the display panel is not correct, the subsequent steps are not performed, and the display panel is directly screened out and does not enter the brightness compensation station of the production line machine, at which time the invalid work amount of the brightness compensation station of the production line machine can be reduced, which is equivalent to improving the efficiency of brightness compensation.

[0059] It should be noted that in the embodiments of the present application, determining whether the control board of the display panel is correct is equivalent to determining whether the display panel currently on the production line machine ready to enter the brightness compensation station is the same model or the same type of display panel as the display panel expected to enter the brightness compensation station, so as to avoid mixing other models of display panels that are not suitable for the production line during the production process of the production line, thereby causing the display panel to not work normally.

[0060] In some embodiments, the method for determining whether the control board is consistent with the control board of the display panel after the in-factory debugging comprises: obtaining the related information of the display panel after the in-factory debugging; reading the related information of the display panel at the brightness compensation station; and determining that the control board is correct in response to the related information of the display panel read at the brightness compensation station being consistent with the related information of the display panel after the in-factory debugging.

[0061] In the embodiments of the present application, the method for determining whether the control board of the display panel is correct can be that first, the control board of the display panel is powered on to make the control board of the display panel in an operating state, then the production line machine reads the related information of the display panel at the brightness compensation station, and simultaneously, the production line machine obtains the related information of the display panel after the in-factory machine debugging, and the related information of the display panel at the brightness compensation station is compared with the related information of the display panel after the in-factory machine debugging, and if the two are consistent, it is determined that the control board of the display panel is correct and not misassembled. If the two are inconsistent, it indicates that the control board is misassembled.

[0062] It should be noted that the in-factory machine stores the related information of the display panel in a header file form after the in-factory machine performs the debugging on each display panel, and the information is published to the production line machine. Before the production line machine performs the brightness compensation determination, the production line machine also reads the header file form of the display panel, and compares the data published by the in-factory machine, so as to determine whether the control board is correct.

[0063] In some embodiments, the in-factory debugging comprises automatically adjusting the gamma correction algorithm debugging of the display screen.

[0064] In the embodiments, the in-factory machine first performs the in-factory debugging on the display panel, and the in-factory debugging comprises automatically adjusting the gamma correction algorithm debugging of the display screen, so that the gamma curve of the display panel can be preliminarily adjusted and corrected. Then, some display panels can meet the display brightness and contrast requirements of the display panel of the type after the automatic adjustment of the gamma correction algorithm debugging of the display screen, and therefore, the subsequent brightness compensation is not required. Alternatively, after the in-factory debugging, some display panels cannot perform the DGC algorithm brightness compensation, and therefore, the brightness compensation is not performed at the brightness compensation station.

[0065] In some embodiments, the related information of the display panel after the in-factory machine debugging comprises the type of the display panel, the driving architecture, and the storage unit type.

[0066] In the embodiments, by comparing the related information of the display panel after the in-factory machine debugging with the related information of the display panel at the brightness compensation station of the production line machine, it can be directly determined whether the control board of the display panel at the brightness compensation station is correctly assembled.

[0067] In some embodiments, the method for confirming that the control board is correct comprises: obtaining, through the relevant information of the display panel, a file integrity check value in the header file of the control board of the display panel after factory debugging, and a file integrity check value in the header file of the control board of the display panel read by the brightness compensation station; comparing the two file integrity check values; and in response to the two file integrity check values being equal, determining that the control board is correct.

[0068] In the present embodiment, the file integrity check value in the header file stored in the control board is unique, and determination of the check value can also be used to determine whether the two control boards are the same control board. Therefore, in the present embodiment, the file integrity check value stored in the storage unit of the control board of the display panel of the brightness compensation station of the production line machine is first read; the file integrity check value in the header file of the control panel of the display panel after factory debugging is obtained from the relevant information of the control panel of the display panel after factory debugging, which is equivalent to the initial basic information of the display panel; the check value of the control board of the display panel after factory debugging is compared with the file integrity check value of the control board of the display panel on the production line machine, and if the two check values are consistent, it is determined that the control board of the display panel on the production line machine is correct.

[0069] The technical solutions of the present application are described below with reference to a specific embodiment.

[0070] In the present embodiment, the brightness compensation refers to DGC algorithm compensation, and the first byte in the header file of the storage unit of the display panel is selected to add a brightness compensation indication bit, wherein each byte is a hexadecimal bit, represented as 0x00. Among them, the first value is selected as 0: indicating that the DGC algorithm is applied, the second value is selected as 1: indicating that the DGC algorithm is skipped, and 2-255 (0x10h-0xffh): reserved. At this time, the brightness compensation method of the display panel of the present embodiment comprises the following steps:

[0071] Powering on the control board;

[0072] The production line machine compares the file integrity check values in the header file to confirm that the control board of the display panel is correct;

[0073] The production line then reads the judgment byte of the brightness compensation indication bit in the header file;

[0074] If the judgment byte of the brightness compensation indication bit is 0, the DGC algorithm configuration parameters of the production line machine remain unchanged, and the DGC algorithm compensation is performed;

[0075] If the judgment byte of the brightness compensation indication bit is 1, the production line machine automatically modifies the configuration parameters, skips the DGC algorithm compensation, and enters the next station.

[0076] Correspondingly, the embodiment of the present application provides a display panel brightness compensation system, which adopts the display panel brightness compensation method of any one of the foregoing embodiments, and comprises a judgment module, a compensation module, an automatic adjustment module and a control module. The judgment module is configured to judge whether the display panel needs to be compensated in brightness. The compensation module is configured to compensate the display panel in brightness. The automatic adjustment module is configured to automatically modify configuration parameters. The control module is connected with the judgment module, the compensation module and the automatic adjustment module, and is configured to acquire the judgment result of the judgment module and control the compensation module to compensate the display panel in brightness or control the automatic adjustment module to automatically modify the configuration parameters.

[0077] The display panel brightness compensation system of the present application is applied to the display panel brightness compensation method. The judgment module is configured to judge whether the display panel needs to be compensated in brightness. Then the compensation module is configured to compensate the display panel in brightness. The automatic adjustment module is configured to automatically modify configuration parameters.

[0078] In some embodiments, an information reading module is configured to read header file information of the display panel. The information reading module is connected with the control module. A data comparison module is configured to compare whether the information read by the information reading module is consistent with the information of the display panel after factory debugging. The data comparison module is connected with the control module.

[0079] In the embodiment of the present application, first, the information reading module reads the header file information in the storage unit of the display panel, and the data comparison module compares the header file information in the storage unit with the information of the display panel published by the factory machine to determine whether they are consistent, so as to determine whether the control board of the display panel on the production line machine is correct. If the control board is not correct, the subsequent judgment steps are not performed, thereby realizing the preliminary screening of the display panel and effectively improving the efficiency. Then, the judgment module judges whether the display panel screened by the data comparison module needs to be compensated in brightness. If the display panel needs to be compensated in brightness, the compensation module compensates the display panel in brightness. If the display panel does not need to be compensated in brightness, the automatic adjustment module automatically modifies the configuration information, skips the brightness compensation station and enters the next process.

[0080] In the foregoing embodiments, the description of each embodiment has its own focus. The parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.
