Abstract

The invention discloses an LCD device for improving image reading quality, which at least includes a liquid crystal cell and a back light module unit. The liquid crystal cell contain a first floor glass substrate, a second layer glass substrate and liquid crystal sealed between the two layer glass substrates, wherein the first floor glass substrate is provided with a thin-film transistor layer and a pixel array, the second layer glass substrate is provided with a colorful optical filter layer, and the back light module unit locates at the external side of the second layer glass substrate of the liquid crystal cell. The first floor glass substrate is provided with a photoelectric sensor array respectively corresponding to each colorful optical filter of the colorful optical filter layer. The pixel of the pixel array is internally provided with a feedback circuit in order to maintain optical output performance stabilization of each pixel.

Description

technical field [0001] The invention discloses a liquid crystal display device, in particular to a liquid crystal display device capable of improving image display quality. Background technique [0002] Referring to Fig. 1, in prior art thin film transistor liquid crystal display (TFT-LCD, Thin FilmTransistor-Liquid Crystal Display), liquid crystal cell (cell) is made of at least first layer glass substrate 1 and second layer glass substrate 2 and The liquid crystal sealed between two glass substrates 1 and 2 is composed of a color filter layer 20 on the first glass substrate 1, and a thin film transistor (TFT) 25 on the second glass substrate 2, and the thin film transistor ( TFT) 25 is usually on the same side of the liquid crystal cell 4 as the display backlight 31, so that the thin film transistor (TFT) 25 is deposited on the peripheral area of ​​the glass substrate 2 close to the backlight 31 to play the role of a photoelectric sensor to detect the surrounding brightne...
