Abstract

The invention provides a liquid crystal display. The liquid crystal display comprises a liquid crystal module, a backlight module, a driving and detecting module and a plurality of light sensors, wherein the liquid crystal module consists of a polarizer, a glass substrate, liquid crystal, a color filter, a thin film transistor, a black matrix, a plurality of conductive wires and the like; the backlight module comprises a light source, a light guide plate, a diffuser sheet and the like; the driving and detecting module comprises a data driver, a gate driver, a light sensor driver, a light sensing detector and the like; the plurality of light sensors consist of P-N diodes or thin film transistors; one light sensor is arranged on each pixel unit respectively; and the plurality of light sensors are used for sensing red and infrared radiation which is transmitted by the light source, passes through the liquid crystal module and is then reflected back by touch fingers of a light touch liquid crystal user and passes through the color filter, so that a sense signal is output for judging a finger touch position.

Description

technical field [0001] The present invention relates to a liquid crystal display, in particular to an optical touch liquid crystal display. Background technique [0002] Information, energy and biology are three very important technologies for human beings at present. The two most important cornerstones of information technology are displays and semiconductor integrated circuits. The display is a window for information transmission between man and machine, and it has become an indispensable and important device for modern people. Displays are widely used, ranging from small-sized mobile phones, digital cameras, and camcorders, medium-sized notebooks and desktop computers, to large-sized home TVs and projection equipment. There are many types of displays, the main ones are cathode ray tube (CRT) display, liquid crystal display (LCD), plasma display panel (PDP), light emitting diode (LED) display panel, field emission display (FED), vacuum fluorescent display panel (VFD), a...
