Abstract

The pixel array base plate includes base plate and following parts configured on the base plate: scanning wires, data wires, active elements, pixel electrodes, multiple first patternized floating placed metals, and multiple first patternized connection conducting wires. Being in crisscross mode, data wires and scanning wires form multiple pixel areas. Each active element connects corresponding scanning wire, data wire and pixel electrode electrically. Moreover, each first patternized floating placed metal and any data wire are overlapped partially. Crossing over any one scanning wire, each first patternized connection conducting wire and first patternized floating placed metal on two sides of scanning wire are overlapped partially.

Description

technical field [0001] The invention relates to a semiconductor element substrate, and in particular to a pixel array substrate. Background technique [0002] With the advancement of modern video technology, various displays have been widely used on the display screens of consumer electronic products such as mobile phones, notebook computers, digital cameras and personal digital assistants (PDAs). Among these displays, liquid crystal displays (LCDs) and organic electroluminescent displays (OLEDs) have become the mainstream in the market due to their advantages of light weight, small volume, and low power consumption. Whether it is a liquid crystal display or an organic electroluminescent display, the manufacturing process includes forming a pixel array substrate by semiconductor technology. By correspondingly adjusting the colors displayed by each pixel in the pixel array substrate, the display can generate images. [0003] FIG. 1 is a partial top view of a known pixel arr...
