Array substrate of display panel and testing method and display method of display panel

Abstract

The invention relates to an array substrate of a display panel and a testing method and a display method of the display panel. The array substrate of the display panel comprises a substrate, a first data line and at least one second data line, a first display data input pad and at least one second display data input pad, a first switch element and at least one second switch element, a testing line and at least one bypass line, wherein the output end of the first switch element is electrically connected with the first data line; the output end of the second switch element is electrically connected with the second data line; the input end of the first switch element and the input end of the second switch element are both electrically connected with the first display data input pad; the testing line is electrically connected with the first display data input pad; and the bypass line is respectively electrically connected with the second display data input pad and the second data line. The invention can reduce the manufacturing cost and the testing time of the array substrate.

Description

technical field [0001] The invention relates to an array substrate of a display panel, a testing method and a display method of the display panel, especially a display panel which can be tested by using a small number of test signal input pads, and a testing method and a display method thereof. Background technique [0002] A display panel, such as a liquid crystal display panel, is mainly composed of an array substrate, a color filter substrate (CF substrate), and liquid crystal molecules filled between the two substrates. The sub-pixel regions are arranged in a shape, and each sub-pixel region includes components such as gate lines, data lines, common lines, and thin film transistors. With the increasing popularity of liquid crystal display applications, consumers' requirements for the resolution and pixel aperture ratio of liquid crystal displays are also increasing. In order to meet the specifications of high resolution and high pixel aperture ratio, the line width of th...

Problems solved by technology

However, according to the known test structure of the array substrate of the display panel, one test line 181 corresponds to one data line DL, and a single test signal input pad 20 can only correspond to 12 data lines DL, so a large number of test lines 181 and test signals must be arranged. input pad 20

For example, if the number of data lines DL in the pixel array 14 is 1080, then 1080 test lines 181 and 90 test signal input pads 20 must be provided, which will greatly increase the manufacturing cost of the array substrate of the display panel. and test time
