capacitive touch screen structure, the first layer is glass, plus a layer of film material. That is, glass cover + OCA + thin film sensor. The glass cover plays a role in protecting the screen and optimizing the surface texture. It is generally made of tempered glass material with high strength, high hardness and good light transmittance. OCA is a solid optical adhesive with good adhesion and light transmittance. It is used for lamination between glass covers and thin film sensors. The thin film sensor is the signal function layer of the capacitive screen, which transmits touch signals and realizes the touch function. Application range of this structure: Suitable for low-cost products below 3.5 inches.
To sum up the structure of the capacitive touch screen, the capacitive touch screen can be simply regarded as a screen composed of four layers of composite screens: the outermost layer is a glass protective layer, followed by a conductive layer, and the third layer is non-conductive glass Screen, the fourth innermost layer is also a conductive layer. The innermost conductive layer is a shielding layer, which plays a role in shielding internal electrical signals. The middle conductive layer is a key part of the entire touch screen. There are direct leads on the four corners or four sides, which are responsible for detecting the position of the touch point.
