LCD TOUCH SCREEN AND APPLICATIONS INTEGRATING SINGLE LAYER CAPACITIVE SENSOR

摘要

It relates to an LCD touch screen and applications integrating single layer capacitive sensor, comprising first underlayer, second underlayer, liquid crystal imaging material and control circuit. It also comprises capacitive touch sensor, which comprises an electrode layer set between the said first underlayer and second underlayer. The said electrode layer comprises electrodes and electrode conductors which are used for electric connection of various electrodes; both of the said electrodes and electrode conductors are set in the same plane. In the invention, the single layer capacitive sensor is set inside of the LCD touch screen, so as to reduce the thickness of the LCD touch screen, conforming to the development tendency of LCD touch screen to thin even ultra-thin ones. In addition, the invention has taken advantage of shielding effect of the black matrix, at the same time of shielding pixel electrode matrix, electrodes and the electrode conductors for the capacitive sensor are also shielded, thus, using effect of the capacitive touch sensor has been enhanced and manufacturing cost is reduced.
