4-wire Touch screen

We have excellent staff and extensive production experience, can produce a wide range of Touch screen 1.Available Size:3"-11" 2.High-resolution 3.High-speed response 4.high stability, and never drift Touch screen (Touch panel), also known as touch panel, is to receive input signals such as sensor contact liquid crystal display device, when exposed to the graphic buttons on the screen, the screen on the tactile feedback system can be programmed according to pre-program drive all connected devices can be used to replace the mechanical button panel, and through the LCD screen to create a vivid audio-visual effects 4-wire resistive touch screen is the preferred solution for low cost applications. It consists of a conductive bottom layer ITO Film and a conductive top layer (ITO Film).The two layers are suspended by many very small spacer dots When a certain point is touched, the top layer contacts the bottom layer and a voltage charged by the controller is applied to the bottom layers electrodes. The controller can detected the touch point by the position on the X and Y-axis. 4-wire General specificationAvailable Size:3"-11"Touch Activation Force:20g 150gThickness:ITO Film:0.188mmOperating Voltage:Less than 12VOperating Current:DC50mA/5VX,Y Resistance:according to the sizeInsulation Resistance:≥20MΩ/25V(DC)Linearity:≤1.5%Response Time:<10msTransparency:≥75%Surface Disposal:Anti Glare, GlareOperating Temperature:-20°C +70°C,≤70%RH,noncondensingStorage Temperature:-30°C +80°C,≤90%RH,noncondensingHumidity:<95%Surface Hardness:3HPen Hitting Life:1millions timesPen Sliding Durability:100thousand timesworks of touch screen: We must first of all with your fingers or other objects touch display installed in front of the touch screen, then the system under the fingers touch the icon or menu choice to locate the position information input. Touch screen touch detected by the touch screen controller components and composition; touch detection parts installed in the front of the monitor screen for detecting user touch position, touch screen controller to accept evacuation; and touch screen controller's main role is to touch detection device from receiving touch information and convert it into contact coordinates, and then sent to CPU, CPU is also capable of receiving the order and sent to the Executive. We are manufactory, we are the source, so our price is very competitive on the market. If you are interested in our products, please don't hesitate to contact us. Look forward to your enquiry!
