Abstract

The invention relates to the technical field of display, in particular to a processing method of a display panel and a display panel. A method for processing the display panel includes preparing a cleaned substrate, sputtering and forming a first metal layer on the substrate, processing the first metal layer to form a gate metal layer, and dropwise coating the side of the gate metal layer to forma light shielding layer attached to the substrate. The light-shielding layer formed by drip coating can effectively reduce the parasitic capacitance of the first metal layer and avoid the miswriting of pixel voltage caused by excessive parasitic capacitance. At the same time, the drift of threshold voltage under bias voltage can be reduced, and the probability of image residue can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a processing method of a display panel and the display panel. Background technique [0002] At present, the TFT-LCD (Thin Film Transistor-Liquid Crystal Display) thin film liquid crystal display mainly adopts that each pixel is controlled by a TFT (Thin Film Transistor) switch, the gates of the TFT switches are connected together to form a gate line, and the source layer is connected to the Together they form a signal line. When a voltage is applied to the gate layer G (Gate) of the TFT, the TFT can be turned on, and at the same time, the display data reaches the drain layer D (Drain) of the TFT through the signal line and the turned-on TFT. Form an electric field and charge the liquid crystal to realize the display effect. [0003] The larger the on-state current of the TFT of the ideal TFT-LCD display, the better, and the smaller the off-state current, the better. In order ...
