Problems solved by technology

The disadvantage of the prior art display panel is that when static electricity is generated on a test line, it is easy to discharge at a certain switching element 161, causing damage to the switching element 161, and the data line 121 connected to the damaged switching element 161 will display abnormal
The frequent occurrence of such display abnormalities brings great troubles to the manufacture of liquid crystal display panels, and the maintenance cost is very high. Therefore, how to overcome this problem is a problem actively explored by the industry.

Abstract

The invention relates to a display panel capable of reducing the display abnormity due to static electricity discharge, related to the display panel field, comprising: a baseplate; a plurality of first signal lines on the baseplate; at least two first testing lines on the baseplate; a plurality of first switch elements on the baseplate, wherein the input terminals of the first switch elements are connected with one first testing line and the output terminal of each first switch element is correspondingly connected with a first terminal of the first signal line; a first control line for connecting the control terminals of the first switch elements on the baseplate; an electrostatic protection device respectively set on the first control line and between at least two testing lines.

Description

【Technical field】 [0001] The present invention relates to a display panel, in particular to a liquid crystal display panel. 【Background technique】 [0002] In recent years, the flat panel display technology including the liquid crystal display technology has been developed by leaps and bounds. figure 1 A schematic top view of a substrate of a liquid crystal display panel in the prior art is shown, which includes a substrate 110 and a plurality of signal lines disposed on the substrate 110 . The plurality of signal lines include a plurality of data lines 121 and a plurality of scan lines 131 . The data lines 121 and the scan lines 131 are interlaced with each other, and two adjacent data lines 121 and adjacent scan lines 131 define a display pixel. figure 2 Yes figure 1 A partial enlarged view of the position of the dotted frame E, the dotted frame E corresponds to the position of the input end of the data line 121 . like figure 2 As shown, the data line 121 has a firs...
