Abstract

The invention provides a display panel to be detected, a display panel and a display device, relates to the technical field of display and aims to improve the problem that data detection signals cannot be normally transmitted when through holes are burnt by ESD. The display panel to be detected comprises a plurality of connection lines arranged in a non-display area and a plurality of lead groups;the lead groups and the connection lines are arranged in different layers; a plurality of data line leads in a same lead group are electrically connected with a same connection line through conductive patterns; the display panel to be detected also comprises auxiliary lines connected with fixed-voltage ends and a semiconductor layer electrically connected with the auxiliary lines and the conductive patterns; the fixed-voltage ends are used for supplying constant-size voltage signals to the auxiliary lines.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel to be tested, a display panel and a display device. Background technique [0002] When preparing a display panel, before attaching the driver chip and the flexible circuit board for inputting display signals to the display panel, a panel function test (full name in English: Cell Test, English abbreviation: CT) is usually carried out to test the production of the display panel. Defects in the process. The testing process is to first input a detection signal to the display panel to make its sub-pixels display a solid-color picture, and judge whether each signal line of the display panel is disconnected or short-circuited, or whether there is light leakage between each sub-pixel, etc. through the display picture. [0003] The pixel arrangement of the traditional display panel is as follows: figure 1 As shown, the color distribution of sub-pixels in each row is the...
