Definitions
- Embodiments of the present invention relate to an array substrate, a display panel, and a method of repairing the same.
- display technology is widely used for display of televisions, mobile phones, and public information
- display panels for displaying pictures are also diverse, and can display a variety of pictures.
- TFT-LCD Thin Film Transistor-Liquid Crystal Display
- OLED organic light emitting display panel
- the driving IC control display panel realizes the function of progressive scanning and frame-by-frame refreshing, so that the image data input to the display panel can be refreshed in real time, thereby realizing dynamic display.
- the source driver IC is responsible for receiving image data, buffering the image data, and converting the digital signal to the analog signal, and finally transmitting the converted signal to each data line of the display panel through the output buffer;
- the gate driver IC is responsible for implementing Line scan, for the timing control to generate the gate-line scan signal that is turned on line by line; after each row of the gate line scan signal is loaded to the corresponding gate line, the control pixel switch is turned on, so that the image data enters the storage capacitor of the row of pixels, and finally the image is realized.
- the normal display is responsible for receiving image data, buffering the image data, and converting the digital signal to the analog signal, and finally transmitting the converted signal to each data line of the display panel through the output buffer;
- the gate driver IC is responsible for implementing Line scan, for the timing control to generate the gate-line scan signal that is turned on line by line; after each row of the gate line scan signal is loaded to the corresponding gate line, the control pixel switch is turned on, so that the image data enters the storage
- the gate drive IC is relatively simple in design and has a single function.
- those skilled in the relevant art began to build a gate integrated driving circuit by using the edge of the display panel to realize the function of the gate driving IC.
- Such a design can omit the separate setting of the gate driving IC in the frame area of the display panel, which is beneficial to realize the narrow frame design of the display panel, and at the same time reduces the production cost of the related products.
- the gate integrated driving circuit comprises a plurality of shift registers, each shift register corresponds to one gate line, a plurality of shift registers are arranged in series, and trigger signals are transmitted step by step between adjacent two shift registers, each After receiving the trigger signal, the shift register outputs a gate line scan signal to the corresponding gate line, and supplies the trigger signal to the next stage unit circuit.
- the shift register may not cause the trigger signal or the shift register of a certain stage due to the presence of tiny particles or the improper setting of the interlayer circuit during the production process of the display panel. Output error The wrong trigger signal, which will cause all the shift registers after this stage to receive or not receive the correct trigger signal, causing the display panel scan to be interrupted, so that the full-screen scan of the display panel cannot be realized.

- the gate integrated drive circuit is bilaterally arranged, that is, as shown in FIG. 1, a set of gate integrated drive circuits are respectively disposed at both ends of the gate line.
- the shift register in the group gate integrated driving circuit is connected to one end of the gate line, and two shift registers are used to drive one gate line together to improve the problem that the shift register is susceptible to scanning interruption.
- a shift interrupt occurs at the shift register at one end of the gate line, and the shift register at the other end of the gate line outputs a scan signal to the gate line.
- the above-mentioned bilateral setting method cannot completely eliminate the hidden danger that the full-screen scanning cannot be performed, because the shift register at both ends of the gate line may have a problem of scanning interruption.
- the shift register at both ends of the gate line may have a problem of scanning interruption.
- the second stage shift register in the gate integrated driving circuit at both ends of the gate line cannot output the trigger signal to the adjacent lower stage normally, all the second stage shift register is caused.
- the shift register does not receive the trigger signal, and thus the scan signal cannot be output to the connected gate line, and the display panel cannot perform full-screen scan. Therefore, which row can be continuously scanned by the display panel depends on which of the two ends of the gate line continuously drives the gate line to scan the shift register, so the method of bilaterally setting the gate integrated driving circuit cannot guarantee the full-screen scanning of the display panel. .
