Touch screen panel 1.Available Size:3"-11" 2.High-resolution 3.High-speed response 4.high stability, and never drift
We have excellent staff and extensive production experience, can produce a wide range of Touch screen1.Available Size:3"-11"2.High-resolution3.High-speed response4.high stability, and never driftTouch 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 effects4-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 dotsWhen 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 specification Available Size:3"-11" Touch Activation Force:20g~150g Thickness:ITO Film:0.188mm Operating Voltage:Less than 12V Operating Current:DC50mA/5V X,Y Resistance:according to the size Insulation Resistance:≥20MΩ/25V(DC) Linearity:≤1.5% Response Time:<10ms Transparency:≥75% Surface Disposal:Anti Glare, Glare Operating Temperature:-20°C~+70°C,≤70%RH,noncondensing Storage Temperature:-30°C~+80°C,≤90%RH,noncondensing Humidity:<95% Surface Hardness: 3H Pen Hitting Life: 1millions times Pen 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.
