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.

Abstract: The present disclosure relates to a display panel and an array substrate including a plurality of pixel cells including colorful sub-pixels and one white sub-pixel. Each of the sub-pixels includes at least one sub-pixel electrode and at least one sub-pixel transistor corresponding to each of the sub-pixel electrode. The sub-pixel transistors are configured within the white sub-pixel to enhance an aperture rate of the colorful sub-pixels. As the sub-pixel transistors are configured within the same white sub-pixel, the brightness of the white sub-pixel may be decreased. At the same time, the aperture rate of the colorful sub-pixels may be greatly enhanced so as to enhance the performance of colorful images.
