Problems solved by technology

However, there are many film layers with low light transmittance in the pixel structure (such as the film layers belonging to the data lines, scanning lines, etc.), when the number of pixel structures in the mobile display device increases, the aperture ratio of the mobile display device also drops sharply
As a result, the mobile display device needs to consume more power to increase the display brightness, which is not conducive to the usable time of the mobile display device

Abstract

The invention provides a pixel structure including a semiconductor pattern, a first insulation layer, a first conductor layer, a second insulation layer, a second conductor layer, a third insulation layer and a pixel electrode. The semiconductor pattern includes a first contact area, a second contact area and a channel area. The first conductor layer includes a brake electrode and a scanning line. A first upper contact opening of the first insulation layer and a first lower contact opening of the second insulation layer form a first contact opening. The semiconductor pattern is exposed in the first contact opening, so that the first contact area is defined. The second conductor layer includes a data line contacting with the first contact area. A side wall of the data line is disposed in an area in the first contact area. The pixel electrode is connected with the second contact area electrically. The line width of the data line is designed to the small, so that an aim of improving opening rate of the pixel structure is realized.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a high aperture ratio pixel structure. Background technique [0002] In recent years, in addition to pursuing high contrast, wide viewing angles, and high color saturation, display devices are also developing towards high resolution. In particular, with respect to mobile display devices, consumers have gradually formed a habit of using mobile display devices to browse webpages or watch audio-visual multimedia, and the resolution of mobile display devices plays an important role in viewing quality. [0003] Generally speaking, the area of ​​mobile display devices is not large. In order to achieve high-resolution mobile display devices, designers need to incorporate multiple pixel structures within a limited area. However, there are many layers with low light transmittance in the pixel structure (such as layers belonging to data lines and scan lines). When the number of pixel stru...
