Pixel structure of thin film transistor liquid crystal display

Abstract

This invention relates to one film transistor LCD pixel structure, which uses three layers of metal layer design to make the data signal line and common electrode set with organic insulation layer to lower register capacitor; the common electrode and pixel electrode are set with passive layer as needed story capacitor for high open rate design.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a pixel structure of a thin film transistor liquid crystal display. Background technique [0002] Liquid crystal display (Liquid Crystal Display; LCD) is widely used because of its advantages of low radiation and small size, and thin film transistor liquid crystal display (Thin Film Transistor LCD; TFT LCD) because of its contrast and viewing angle characteristics, It is still the mainstream display in the market. [0003] Since the liquid crystal material itself does not emit light, the light source of the TFT LCD comes from the backlight source. The backlight source passes through the layers of the TFT LCD such as polarizers, color filters and other materials, and the actual display brightness is only about that of the original light source. 10% or so. For the problem of insufficient display brightness, if the brightness of the backlight module is increased, although the brightness...

Problems solved by technology

Due to the structure designed in Figure 2, although it has a higher aperture ratio compared with the prior art in Figure 1, this pixel design must provide a certain area to act as a storage capacitor for the pixel. When designing a high-resolution panel There is still considerable room for improvement in this design
