Abstract: Disclosed are a pixel structure, an array substrate, and a display panel. In the pixel structure, a stabilizing line is configured to provide a stabilized signal to each pixel unit in a corresponding pixel unit group. When a high grayscale image is displayed, the stabilized signal provided by the stabilizing line is the same as a data signal received by a pixel unit in a turned-on state in the corresponding pixel unit group. Light transmittance and picture contrast of the display panel can be improved when the high grayscale image is displayed.

Abstract: An LTPS array substrate and a method for producing the same are proposed. The method includes: forming an insulating layer, a semiconductor layer, and a first positive photoresist layer on the substrate one by one; exposing one side of the substrate on the opposite side of the gate for forming a polycrystalline silicon layer; forming a source and a drain of the TFT on the polycrystalline silicon layer; forming a pixel electrode on the insulating layer and part of the source; forming a plain passivation layer on a source-drain electrode layer; forming a transparent electrode layer on the plain passivation layer so that the transparent electrode layer is connected to the gate, the source, and the drain via the contact hole. The use of masks in types and numbers in the LTPS technology can be reduced. Thus, both of the processes and the production costs are reduced.
