Abstract

The invention relates to the field of liquid crystal display and discloses an array substrate, a preparation method thereof and a liquid crystal panel. The array substrate comprises a substrate body (1) and multiple pixel units (2) formed on the substrate body (1) in array distribution, and each pixel unit comprises a thin film transistor switch (20) which comprises a grid electrode (200) formed on the substrate body (1). The array substrate can reflect back light going through the grid electrodes, so that utilization efficiency of a backlight source is improved. A mask is used for few times in the preparation method, so that the preparation method is convenient to operate, and production cost is lowered. By applying the array substrate or the array substrate prepared by the preparation method in the liquid crystal panel, the utilization efficiency of the backlight source can be improved, and display power consumption of the liquid crystal panel is lowered.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an array substrate, a preparation method of the array substrate and a liquid crystal panel. Background technique [0002] Among the flat panel displays, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, no radiation and relatively low manufacturing cost, and occupies a dominant position in the current flat panel display market. TFT-LCD generally includes a liquid crystal panel and a backlight module (also called a backlight). The LCD panel itself does not emit light, it displays graphics or characters that are the result of its light modulation. The backlight module is one of the key components of TFT-LCD. It is a light source located behind the thin-film transistor liquid crystal display. It can provide a uniform and high-brightness light source for the liquid crystal panel, so that the TFT-LCD can display images normally. The back...
