A display panel and its detection method

Abstract

The invention discloses a display panel and a detection method thereof. The display panel includes a plurality of pixel units, a plurality of scan lines, a plurality of data lines, and a plurality of gate signal lines; each row of scan lines is provided with only one via hole; the via hole divides the gate signal lines into first One segment and the second segment, the first segment and the second segment are disconnected in the pixel unit where the via hole is located. In the present invention, the traditional wiring via holes are arranged in a linear and dense manner in sequence, and the positions of the via holes are randomly arranged, thereby avoiding the uneven imaging of linear display caused by the linear densely arranged via holes in the display area. And further reduce the standard pixel unit circuit images into a group for comparative analysis, no need to detect and determine the pixel unit circuit images including gate signal traces, vias and open circuit positions, which greatly improves the image detection efficiency and improves the equipment. Test your ability.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a detection method of the display panel. Background technique [0002] In response to market demand, the detection method of large-size, high-resolution and ultra-narrow bezel display panels has become a market trend. With the introduction of narrow bezel technology, gate signal lines (Gate Line), data lines (Data Line) The technology that is designed to the same side as the common electrode trace is called 3in 1 technology, which compresses the three-sided frame to achieve an ultra-narrow frame. Compared with the way in which the gate signal traces and the data traces are arranged on different sides, the width of the frame can be further reduced. [0003] like figure 1 shown, figure 1 It is a schematic diagram of the structure of an existing display panel. Using 3in1 technology, the display panel 90 includes a pixel unit 91, a row driving unit 92 ...

AI Technical Summary

Problems solved by technology

[0005] One purpose of the present invention is to solve the technical problem that the regular linear display is not uniform due to the way that the via holes connecting the row drive lines to the gate lines of the display area are densely arranged in a sequential manner in the display panel; another purpose of the present invention is to solve the problem in the display panel. If the linear arrangement of the via holes is disrupted, the automatic optical inspection machine (AOI) cannot detect or slow down the detection speed when detecting whether there is a short circuit in the pixel circuit during the manufacturing process.
