Abstract

The invention discloses a display panel and a display device, comprising: a touch electrode layer, a touch wire layer and an insulating layer, the insulating layer is arranged between the touch electrode layer and the touch wire layer; the touch electrode layer includes a plurality of Touch electrodes, a plurality of touch electrodes are arranged in an array along the first direction and the second direction; the touch line layer includes a plurality of touch lines, and the plurality of touch lines extend along the second direction; the insulating layer includes a plurality of first An opening and a plurality of second openings, the first opening is used to electrically connect the touch electrode and at least one touch line, and the second opening is used to form a position mark; along the direction perpendicular to the plane where the display panel is located , the depth of the first opening is h1, the depth of the second opening is h2, and the film thickness of the insulating layer is H; wherein, h1=H, h2<H. Compared with the prior art, the setting of the position mark of the display panel is optimized, and the bad position can be quickly located according to the position mark, which is beneficial to reduce the maintenance cost and improve the maintenance efficiency.

Description

Technical field [0001] The present invention relates to the field of display, and more particularly to a display panel and a display device. Background technique [0002] With the rapid development of display technology, LCD Crystal Display, LCDs, and organic Light Emitting Display, OLEDs have become the mainstream display technology products on the current market and have been widely used. However, during the production process of the display, due to various uncontrollable factors, some adverse phenomena often occurs, serious or even cause the display screen batch, bring huge losses to the manufacturer. [0003] In these poor phenomena, for some specific areas, lines, etc. can be solved by repair. During the maintenance process, the location of bad areas, bad lines requires precise positioning, but current positioning mode is mainly used to determine the coordinate information of the poor position using the signal generator, and then determines whether the coordinate information...
