Abstract

The invention discloses a capacitive touch screen with a high discrimination degree. The capacitive touch screen comprises a body, wherein a frame is arranged on the outer side of the body; a waterproof sealant is arranged at the joint of the peripheries of the body and the frame; the body comprises a glass protection layer, a top film, a top ITO (Indium Tin Oxide) coating, an interlayer ITO coating, a bottom film, a shielded ITO coating, a shielding film and a liquid crystal display; the glass protection layer, the top film, the top ITO coating, the interlayer ITO coating, the bottom film, the shielded ITO coating, the shielding film and the liquid crystal display are sequentially arranged from the exterior to the interior; the glass protection layer and the top film are connected througha first OCA (Optical Cement Adhesive); the top ITO coating and the interlayer ITO coating are connected through a second OCA; and the bottom film and the shielded ITO coating are connected through athird OCA. The structure of the capacitive touch screen disclosed by the invention is novel. According to the capacitive touch screen with high discrimination degree and the manufacturing method disclosed by the invention, due to double conductor layers and an induction manner, the overall capacitive touch screen has high discrimination degree, and the capacitive touch screen is high in inductionspeed, low in power consumption and suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a capacitive touch screen with high resolution and a manufacturing method. Background technique [0002] Capacitive touch screen technology uses the current induction of the human body to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Four electrodes, the inner ITO is the shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the electric field of the human body, a coupling capacitance is formed between the user and the surface of the touch screen. For high-frequency currents, the capacitance is a direct conductor, so the finger absorbs a small current from the contact point. This curre...
