Embodiment Construction

[0052] Generally speaking, a liquid crystal display panel is composed of a filter substrate, an array substrate, and a liquid crystal layer sandwiched between the filter substrate and the array substrate. On the aforementioned array substrate, a pixel array structure in which a plurality of pixel units are arranged is fabricated.

[0053] see image 3 , which is a schematic diagram of a pixel unit.

[0054] As shown in the figure, a plurality of scan lines 20 arranged horizontally and a plurality of data lines 21 arranged vertically are provided on the array substrate. A plurality of pixel units 22 can be divided by the scan lines 20 and the data lines 21 . Wherein, each pixel unit 22 includes a transistor 23 , a pixel electrode 24 and a storage capacitor 25 .

[0055] The transistor 23 is a three-terminal element including a gate, a source, and a drain, located at the intersection of the scan line 20 and the data line 21 , and coupled to the scan line 20 and the data line ...

Abstract

A pixel unit includes a transistor, a pixel electrode, and a storing capacitance. Being as a switching element for each pixel unit, the transistor turns on / off the switch to add digital signal to the pixel electrode. The storing capacitance possesses first electrode and second electrode. Multiple through holes are prepared on surface of the first electrode. Next, copying forms of through holes on the first electrode, the film layer covering on the first electrode possesses rough surface in order to obtain effect of increasing reflected light.

Description

technical field [0001] The invention relates to a pixel unit structure, in particular to a pixel unit structure with a micro-reflection structure used in a low-temperature polysilicon liquid crystal display panel. Background technique [0002] Among various image display technologies today, liquid crystal panels have been widely used in various devices due to their advantages of light weight, small size, low power consumption, and no radiation. [0003] Since the liquid crystal panel does not have self-illumination, it needs to rely on external light. Therefore, generally speaking, the liquid crystal panel is installed at the light outlet of a backlight module, and the light generated by the backlight module penetrates various optical films such as diffusion film and polarizer. After layers, enter the LCD panel. By controlling the rotation direction of the liquid crystal molecules in the liquid crystal panel, the brightness and darkness of the light displayed by the liquid ...
