Abstract: The present disclosure provides a display panel and a display device. The display panel includes an array substrate, a bonding area of the array substrate is provided with a plurality of bonding pads and a driving chip. A first area of the driving chip is at least provided with a plurality of first dummy terminals. A height difference caused by warping of driving terminals can be compensated by the first dummy terminals, thereby avoiding a phenomenon of shallow conduction. An insulation protective layer is provided on a part of the array substrate which is corresponding to the first dummy terminals, thereby preventing metal wirings from extrusion damage.

Abstract: The present disclosure provides a display panel and a display device. A distance from a surface of a first conductive adhesive layer close to a first pin, electrically connecting the first conductive pad and the first pin, to the substrate is different from a distance of a surface of a second conductive adhesive layer electrically connected to the second conductive pad and the second pin to the substrate, to compensate for a height difference caused by the partial warpage of the pins on the drive chip when binding a drive chip, so as to ensure that the drive chip can be well bonded to the display panel.

Abstract: The present application provides a display panel and a display device, the display panel is provided with two driving chips disposed side by side in a first border of a non-display area, and a flexible circuit board is disposed between the two driving chips. Compared with the prior art, a longitudinal distance between the driving chip and the flexible circuit board on the display panel border can be reduced, so as to reduce a length of the lower border of the display panel and increase a space of a display area.

IPC: H01L27/12
Abstract: A display panel and an electronic device are provided. In the display panel, first line groups and second line groups are arranged in different layers. In the first line groups, there is a voltage difference between every adjacent pair of gate lines. In the second line groups, there is also a voltage difference between every adjacent pair of gate lines. When a short circuit occurs between adjacent gate lines in the same layer, there is a noticeable change in the voltage on the gate lines, which can be detected through a cell test, effectively reducing the chances of missed detections.
