[0043] Embodiment 1
[0044] Figure 1 A flow chart of a display panel repair method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of detecting and repairing possible driver defects of a display panel. The display panel repair method can be executed by a display panel repair device. The display panel repair device can be implemented in the form of hardware and / or software. The display panel repair device can be configured in an electronic device used for detecting electronic products such as liquid crystal displays. Figure 1 As shown, the display panel repair method includes:
[0045] S110, obtaining a first gate drive voltage of a GIP circuit in the display panel to be repaired, and when the first gate drive voltage is not within a theoretical drive voltage range, replacing a current total printed circuit board of the display panel to be repaired with a target total printed circuit board to obtain a replacement display panel.
[0046] Among them, the display panel to be repaired is a display panel in a liquid crystal display. In this embodiment, the display panel to be repaired is a display panel that may have driving problems and no image problems during the manufacturing process of the liquid crystal display. The display panel to be repaired is offline tested and repaired.
[0047] Specifically, before obtaining the first gate drive voltage of the GIP circuit in the display panel to be repaired, an image inspection is performed on the display panel to be repaired. If there is no image problem, the first gate drive voltage of the GIP circuit in the display panel to be repaired is directly obtained. If there is an image problem, the image defect type of the display panel to be repaired is further determined.
[0048] The GIP (Gate in Panel) circuit is a display control circuit that controls the brightness of the pixels of the liquid crystal display to achieve high-quality image display effects. The GIP circuit is generally composed of an inverter, a driver IC, a sensor, and a controller. Based on this, the first gate drive voltage is the Gate voltage of the TFT in the GIP circuit structure, that is, the power supply voltage of the inverter inside the GIP circuit. Considering the life of the GIP circuit structure, the lower the gate drive voltage of the GIP circuit detected in the early stage, the more beneficial it is to its circuit life.
[0049] The first gate driving voltage may be obtained by measuring a signal and automatically determining it before compensation in the first manufacturing process, or by measuring it with a multi-purpose meter. This embodiment does not impose any limitation on the specific measurement method.
[0050] Specifically, when considering possible driving problems of the display panel to be repaired, priority is given to replacing its total printed circuit board, that is, when the first gate driving voltage is not within the theoretical driving voltage range, the current total printed circuit board of the display panel to be repaired is replaced with the target total printed circuit board to obtain a replacement display panel.
[0051] Based on the above, if the first gate drive voltage is within the theoretical drive voltage range, it is considered that the display panel to be repaired does not have a driving problem, and the display panel to be repaired can continue to be put into the manufacture of liquid crystal displays, and the first gate drive voltage and the display panel to be repaired can be noted correspondingly in the manufacturing execution system.
[0052] The manufacturing execution system, namely the MES system (abbreviated as MES, also known as the production management system), is mainly responsible for workshop production management and scheduling, and is used to track and record the production conversion from raw materials to finished products. In this embodiment, the manufacturing execution system can be used to record the materials and specific process operations in the manufacturing process of the liquid crystal display, that is, to record the usage of the display panel and information such as the yield rate.
[0053] S120: If the second gate drive voltage of the GIP circuit in the replacement display panel is not within the theoretical drive voltage range, and the target total printed circuit board has completed the aging test, the total number of printed circuit board replacements for replacing the current total printed circuit board of the display panel to be repaired with the target total printed circuit board is obtained.
[0054] Among them, the second gate driving voltage is the gate driving voltage measured again after the display panel replaces the main printed circuit board. Similarly, the second gate driving voltage can be measured by a multi-purpose meter or by other means. This embodiment does not impose any restrictions on the specific measurement method.
[0055] It can be known that after obtaining the replacement display panel, continue to detect the second gate drive voltage of the GIP circuit in the replaced display panel. If the second gate drive voltage is within the theoretical drive voltage range, it means that the replaced display panel is a good product. Further, the second gate drive voltage and the current total printed circuit board of the display panel to be repaired can be replaced with the target total printed circuit board and the corresponding notes of the display panel to be repaired are sent to the manufacturing execution system.
[0056] Furthermore, if the second gate drive voltage of the GIP circuit in the replacement display panel is not within the theoretical drive voltage range, and the target total printed circuit board has not completed the aging test, the target total printed circuit board is controlled to perform the aging test; the target total printed circuit board of the display panel to be repaired is replaced with a target total printed circuit board that has completed the aging test to obtain an updated display panel, and a third gate drive voltage of the updated display panel is obtained; and it is determined whether the updated display panel needs to be repaired based on the third gate drive voltage.
[0057] It can be understood that the aging test of the target total printed circuit board refers to testing the printed circuit board (PCB) under certain temperature, humidity, voltage and current conditions to evaluate its reliability and life in actual use. The aging test is carried out before the LCD display goes off the production line, so here it is to determine whether the target total printed circuit board at this time has completed the aging test before going off the production line.
[0058] It should be noted that, when the current total printed circuit board of a display panel to be repaired is replaced with the target total printed circuit board, the corresponding total printed circuit board replacement times are increased by 1. For the same display panel to be repaired, the total printed circuit board replacement times based on the replacement target are the total printed circuit board replacement times, and the total printed circuit board replacement times change with the replacement of the total printed circuit boards.
[0059] S130. If the total number of replacements of the printed circuit board exceeds the set number of replacements, the display panel to be repaired is handed over to the process quality control system, and a driving fault instruction of the display panel to be repaired is generated, so as to prompt the display panel to be repaired and reassembled based on the driving fault instruction.
[0060] Among them, the process quality control system is the PQC (Process Quality Control) system, also known as the process quality control system, which is a system for quality control of the manufacturing process of liquid crystal displays.
[0061] Specifically, when the total number of printed circuit board replacements exceeds the set number of replacements, it is considered that the display panel to be repaired may have not only driving problems but other problems. The display panel to be repaired will be handed over to the process quality control system, which will further process the display panel to be repaired.
[0062] It can be seen that if the total number of replacement times of the printed circuit boards does not exceed the set number of replacement times, the current total number of printed circuit boards of the display panel to be repaired is replaced again, and the total number of replacement times of the printed circuit boards is controlled to increase by 1.
[0063] On the basis of the above, the fourth gate driving voltage of the display panel to be repaired is obtained based on the driving fault instruction, and it is determined whether to repair and reconstruct the display panel to be repaired according to the fourth gate driving voltage.
[0064] The driving fault instruction may be a control instruction given by a process quality control system or other test system, and the driving fault instruction is used to control further repair and reorganization of the display panel to be repaired.
[0065] The fourth gate drive voltage is the gate drive voltage of the current GIP circuit obtained in real time after the total number of printed circuit board replacements exceeds the set number of replacements. If the fourth gate drive voltage is higher than the voltage upper limit value, or the fourth gate drive voltage is lower than the voltage lower limit value, it indicates that the display panel to be repaired at this time needs to be repaired and reorganized, and the display panel to be repaired is repaired and reorganized, that is, after completely removing the parts of the display panel to be repaired, any parts can be selectively replaced and then reorganized to obtain a new display panel. If the fourth gate drive voltage is between the voltage upper limit value and the voltage lower limit value, it indicates that the display panel to be repaired at this time may have other problems, and other problems of the display panel to be repaired can continue to be checked.
[0066] It can be understood that the setting of the voltage upper limit value and the voltage lower limit value means that if the limit value is exceeded at this time, the cause of the failure of the display panel to be repaired cannot be located, and therefore further repair and reorganization is required. The specific voltage upper limit value and the voltage lower limit value can be selected and set according to the actual display requirements of the display panel. The present embodiment does not impose any restrictions on this. Optionally, the voltage upper limit value may be 9V, that is, if the fourth gate drive voltage exceeds 9V, the cause of the failure of the display panel to be repaired cannot be located, and the display panel to be repaired needs to be further repaired and reorganized. Similarly, the voltage lower limit value may be 0.2V, that is, if the fourth gate drive voltage is lower than 0.2V, the cause of the failure of the display panel to be repaired cannot be located, and the display panel to be repaired needs to be further repaired and reorganized.
[0067] The technical solution of the embodiment of the present invention is to obtain the first gate drive voltage of the GIP circuit in the display panel to be repaired, and when the first gate drive voltage is not in the theoretical drive voltage range, replace the current total printed circuit board of the display panel to be repaired with the target total printed circuit board to obtain a replacement display panel; if the second gate drive voltage of the GIP circuit in the replacement display panel is not in the theoretical drive voltage range, and the target total printed circuit board has completed the aging test, then obtain the total number of printed circuit board replacements of the current total printed circuit board of the display panel to be repaired and replaced with the target total printed circuit board; if the total number of printed circuit board replacements exceeds the set number of replacements, the display panel to be repaired is handed over to the process quality control system, and a drive fault instruction of the display panel to be repaired is generated, so as to prompt the repair and reorganization of the display panel to be repaired based on the drive fault instruction. The present invention solves the problem that it is currently impossible to make timely judgments on the drive problems of the display panel in the liquid crystal display, avoid misjudgment, and cause excessive waste of the display panel, and realizes the maximum reduction of display panel waste by replacing the total printed circuit board, improves the recovery rate, and at the same time, reduces the generation of subsequent display panel irregular stripes or vertical line defects, and reduces the production cost of the production plant.
[0068] Embodiment 2

Based on the above embodiment, this embodiment further implements the display panel repair method based on the total number of printed circuit board replacements and the quality control system of handing over the display panel to be repaired when the total number of printed circuit board replacements exceeds the set number of replacements, and provides an optional implementation method. Figure 2 As shown, the display panel repair method includes:
[0070] S210, determining whether the display panel to be repaired has image defects, if so, executing step S211, if not, executing step S212.

[0072] S211, obtaining a first gate driving voltage of a GIP circuit in a display panel to be repaired, and executing step S213.

[0074] S212: Determine the image defect type of the display panel to be repaired.
[0075] Specifically, if it is determined that the display panel to be repaired has an image defect, the image defect type of the display panel to be repaired is further determined. The image defect type may be an image drive defect or a defect that occurs when the gate drive circuit is directly formed on the lower glass substrate through the gate process within the panel, etc. This embodiment does not impose any restrictions on this.
[0076] S213, determining whether the first gate driving voltage is within the theoretical driving voltage range, if so, executing step S214, if not, executing step S215.

The specific annotation form can adopt the existing annotation method, and this embodiment does not impose any limitation on this.
[0080] It can be known that after the first gate driving voltage and the display panel to be repaired are noted in the manufacturing execution system, it means that the driving problem of the display panel to be repaired has been eliminated and the display panel to be repaired can be put back into the LCD manufacturing line.

[0088] It can be known that the aging test is performed on the target total printed circuit board here, and the target total printed circuit board is returned to the liquid crystal display manufacturing line for aging test. The aging test in this embodiment can be a 24-hour aging test on the target total printed circuit board, or it can be a test at other times. This embodiment does not impose any limitation on this.

[0090] The updated display panel is a display panel that has been configured as a target total printed circuit board that has completed the aging test.
[0091] The third gate drive voltage is the gate drive voltage of the GIP circuit in the display panel measured after replacing the target total printed circuit board that has completed the aging test. Similarly, the third gate drive voltage can be measured by a multi-purpose meter or by other means. This embodiment does not impose any limitation on the specific measurement method.
