Problems solved by technology

Among them, the vector pressure sensing technology touch screen has withdrawn from the stage of history; the infrared technology touch screen is cheap, but its frame is fragile, easy to generate light interference, and distortion in the case of a curved surface; the capacitive technology touch design is reasonable, but its image distortion problem is difficult It has been fundamentally solved. Capacitive technology touch screen is accurate in positioning, but its price is high, and it is afraid of being scratched and easily damaged. Surface acoustic wave touch screen solves various defects of previous touch screens. It is clear and not easy to be damaged. It is suitable for various occasions. The disadvantage is that the screen surface If there are water droplets and dust, the touch screen will become dull or even not work

Abstract

The invention discloses an inductive liquid crystal display key screen, which mainly comprises a single-side ITO glass, a double-side ITO glass, a glue frame, a first display electrode, a first alignment film, a second display electrode, a second alignment film, a liquid crystal, a first polaroid, an inductive electrode ITO layer and a second polaroid. The glue frame is arranged between the single-side ITO glass and the double-side ITO glass. The first display electrode is coated to an ITO conductive layer of the single-side ITO glass, and the first polaroid is stuck to the other side of the single-side ITO glass. The first alignment film is printed on the first display electrode. The second display electrode is coated to an ITO conductive layer of the double-side ITO glass. The second alignment film is printed on the second display electrode. A closed accommodating space is formed among the glue frame, the first alignment film and the second alignment film; and the liquid crystal is filled in the accommodating space. The glue frame is provided with a group of conductive points to conduct the first display electrode and the second display electrode. The inductive electrode ITO layer is screen-printed on the other ITO conductive layer of the double-side ITO glass. The second polarizing plate is stuck to the inductive electrode ITO layer.

Description

technical field [0001] The invention relates to an inductive liquid crystal display button screen. Background technique [0002] From the beginning of people using mechanical buttons, to the touch-type MP3 and MP4 in the streets and alleys, to touch-type mobile phones, digital cameras, PC tablets, induction cookers, microwave ovens, air conditioners, refrigerators, freezers, solar water heaters, electronic scales, fingerprint locks , electronic door locks, instruments, sports equipment, etc., it can be said that we are entering a touch era. The touch screen is the most convenient, simple, natural and intuitive input means. With the improvement of modern people's requirements for saving space and the aesthetics and interactivity of the man-machine display interface, traditional mechanical keys and traditional touch screens will be replaced by inductive LCD key screens to a large extent. To distinguish touch screens from the technical principles, they can be divided into fiv...
