Problems solved by technology

[0006] 1. The cover plate and the casing are made and connected separately, and the dustproof and waterproof performance is poor;
[0007] 2. The transparent cover plate used is made of tempered glass, which is difficult to process and high in cost;
[0008] 3. The cover plate made of tempered glass as the base material is fragile, and the effect of shock resistance and drop resistance is poor, which cannot meet the needs of customers
[0009] The Chinese patent application number 200910107578 discloses the invention patent of "capacitive touch screen and its processing method", which includes a substrate with an air surface and a film surface and a touch screen film layer arranged on the film surface side of the substrate. Touch screen film layer comprises ITO layer, insulating layer, conductive layer and film layer protective layer, and described substrate is tempered glass; There is above-mentioned weak point in this invention equally: capacitive touch screen substrate adopts tempered glass as base material, this The touch screen is easy to break when it falls, and the effect of shock resistance and drop resistance is poor. At the same time, the processing is difficult and the production cost is too high.

Abstract

The invention discloses a casing integrating type capacitance touch screen which comprises a display screen arranged at the bottom for displaying images and an indium tin oxides (ITO) sensor for sensing touch points and further comprises a casing arranged at the top for protecting the display screen, the ITO sensor is arranged on the back surface of the casing, and the casing is of an integral structure. The casing integrating type capacitance touch screen can reduce raw material cost and processing cost, can produce seamless products, improves product airtightness and falling resistance, reduces product thickness and weight and meanwhile beautifies the appearance of the whole machine.

Description

technical field [0001] The invention relates to a capacitive touch screen, in particular to a case-integrated capacitive touch screen. Background technique [0002] Touch screens are composite touch screens used in electronic products such as mobile phones, e-books, and digital cameras, among which capacitive touch screens are the most commonly used type of touch screens. [0003] The capacitive touch screen uses the current induction of the human body to work. The capacitive touch screen is usually a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO (coated conductive glass), and the outermost layer is A thin layer of silica glass protective layer, ITO coating as the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the shielding layer to ensure a good working environment; when the user's finger touches the capacitive touch screen At this time, due to the...
