Thin film transistor array substrate, manufacturing method and liquid crystal display panel

Abstract

The invention provides a thin film transistor array substrate, a manufacturing method and a liquid crystal display panel. The thin film transistor array substrate comprises a substrate, scanning lines, data lines, signal input lines and current feedback lines, wherein the scanning lines, the data lines, the signal input lines and the current feedback lines are formed on the substrate. The scanning lines and the data lines intersect to define multiple sub-pixels. A thin film transistor, a light sensor and a pixel electrode are formed in each sub-pixel. Each thin film transistor comprises a first grid, a first semiconductor, a first source electrode and a first drain electrode. The first grids are connected with the scanning lines, the first source electrodes and the first drain electrodes are alternately arranged and both make contact with the first semiconductors, the first source electrodes are connected with the data lines, and the first drain electrodes are connected with the pixel electrodes. Each light sensor comprises a second grid, a second semiconductor, a second source electrode and a second drain electrode. The second grids do not receive signals, the second source electrodes and the second drain electrodes are alternately arranged and both make contact with the second semiconductors, the second source electrodes are connected with the signal input lines, and the second drain electrodes are connected with the current feedback lines.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a thin film transistor array substrate and a manufacturing method, and a liquid crystal display panel with the thin film transistor array substrate. Background technique [0002] With the development of display technology, liquid crystal display panels (Liquid Crystal Display, LCD) are more and more popular due to their advantages of lightness and low radiation. The liquid crystal display panel includes a thin film transistor array substrate and a color filter substrate arranged oppositely, and a liquid crystal layer sandwiched between them. [0003] When the display panel is in different external environments, there will be more light components of a certain color in the external light, for example, more red light, and the normal display of the panel will be redder. In addition, short-wavelength light affects the retina of the human eye and can easily induce reti...
