Abstract

The invention provides a liquid crystal pixel and the making method and LCD thereof. And the liquid crystal pixel comprises a data line, a doped polycrystalline layer and a shielding metal layer, where the doped polycrystalline silicon layer is located under the data line and the vertical projection of the polycrystalline silicon layer does not overlap the data line; the shielding metal layer is located between the data line and the doped polycrystalline silicon layer and form a storage capacitor together with the polycrystalline silicon layer. In addition, the invention also provides a liquid crystal pixel making method, which stores video data by the store capacitor and can not cause burden to the data line but can avoid possible parasitical capacitor between the pixel electrode and the data line.

Description

technical field [0001] The invention relates to the field of liquid crystal pixels, and particularly relates to a liquid crystal pixel capable of reducing the load of data lines in a liquid crystal panel, a manufacturing method thereof and a liquid crystal display. Background technique [0002] In recent years, due to the rapid development of liquid crystal displays and many advantages such as light weight, low power consumption and zero radiation, they are widely used in various electronic products. In a general active matrix liquid crystal display, the liquid crystal pixels are arranged in an array, and the action of each liquid crystal pixel is controlled by an active element such as a thin film transistor. [0003] Please refer to FIG. 1 , which shows a schematic diagram of a display array in a conventional liquid crystal display. The display array 100 includes several scan lines 102 and several data lines 104 , and the scan lines 102 and the data lines 104 intersect to...
