Problems solved by technology

[0005] Since the existing liquid crystal cell detection circuit can only display figure 2 and image 3 The solid color picture and the horizontal color bar picture shown in the picture can not show the picture with the color difference in the horizontal direction, so at present, the crosstalk detection of the display panel can only be carried out in the subsequent process
However, if the crosstalk problem of the display panel is found in the subsequent process, it will increase the production cost and waste resources

Abstract

The invention discloses a detection circuit, a detection method and a display panel. The detection circuit comprises 2N pieces of signal input lines which are divided into N pairs of signal input lines and are in charge of offering data signals to a plurality of data lines of the display panel, wherein the various data lines on the display panel are continuously grouped into M groups of data lines, wherein every two adjacent groups of data lines of the M groups of data lines are each connected to different pair of the N pairs of signal input lines; and every two adjacent data lines of each group of the M groups of data lines are each connected to different signal input lines of each pair of signal input lines, wherein N is an integer which is greater than 1 and M is an integer which is greater than or equal to N.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a detection circuit, a detection method and a display panel of a display panel. Background technique [0002] The cell test process is an important link in the thin film transistor liquid crystal display (TFT-LCD) process. The quality of the liquid crystal cell is tested by lighting the liquid crystal cell. Subsequent manufacturing can only be carried out when the liquid crystal cell inspection is qualified. When the liquid crystal cell inspection is unqualified, it is necessary to improve the design or process to save production costs in the subsequent manufacturing process, which is very important for the improvement of the yield rate of the product. effect. [0003] In the currently commonly used display panel design solutions, limited by the particularity of the detection circuit of the liquid crystal cell, the detection circuit can only make the liquid crystal cell...
