Abstract

The present invention relates to the technical field of display panels and discloses a display panel and a display device. The display panel includes a lower liner layer, a first metal trace unit, a second metal trace unit, and a third metal trace unit. The first metal trace unit is on the lower liner layer. The second metal trace unit is on the lower liner layer. The third metal trace unit is located above the first metal trace unit and the second metal trace unit and is not in contact with the first metal trace unit and the second metal trace unit, and the third metal trace unit is connectedto a fixed potential. The orthographic projections of the first metal trace unit and the second metal trace unit on the lower liner layer respectively overlap at least partially with the orthographicprojection of the third metal trace unit on the lower linear layer such that the first metal trace unit and the second metal trace unit respectively form a coupling capacitor with the third metal trace unit. In the above manner, the influence of crosstalk caused by the parasitic capacitance between the first metal trace unit and the second metal trace unit can be reduced.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel and a display device. Background technique [0002] Currently, active matrix organic light emitting diode (Active Matrix Organic Light Emitting Display, AMOLED) displays have broad market applications. The pixels in the OLED panel are driven to emit light by the current generated by a driving thin film transistor (Driving Thin Film Transistor, DTFT) in a saturated state. Since there is a parasitic capacitance between the signal line and the gate of the driving TFT in the OLED panel, the voltage change on the signal line will affect the potential of the gate of the driving TFT, causing the problem of crosstalk. Contents of the invention [0003] In view of this, the technical problem mainly solved by the present invention is to provide a display panel and a display device capable of reducing the influence of crosstalk caused by the parasitic capac...
