Resistive Touch Screen for 7 inch AT070TN92 94 LCD Display Panel Raspberry Pi We ship all items for free shipping with tracking number and mark as gift. Brief Introduction 4-wire resistive touch screen is resistive family, the most widely used and most popular one . It consists of a line ( glass or film material ) conductive ITO layer and the upper line ( film material ) conductive ITO layer. Slightly separated by an insulating middle point , when the touch screen surface without pressure , up and down the line is open. Once the pressure applied to the touch screen surface . Vertical line becomes conductive , the controller circuit driving voltage applied to the conductive layer of ITO in the X coordinate direction , the line through the probe the conductive layer of ITO on the detection voltage of the X direction, whereby the contact point of the projected X coordinates. By changing the direction of the applied voltage to the controller , similarly to the measured Y coordinate of the contact , the contact position to clear . Specifications Circuit level : 5V (DC), 35mA Surface hardness : 3H Light transmittance: bright surface material > 83% matte material : > 78% Life: 1 Percussion life:> 1 million times ( single point click ) 2 strokes life> 100,000 times Contact bounce time : <5ms Operating temperature : -10 °C ~ +60 °C ( Humidity : 20 % ~ 85% , non-condensing water droplets ) Storage temperature : -20 °C ~ +70 °C ( Humidity : 20% ~ 90% , non-condensing water droplets ) Resolution: 2048 * 2048 Linearity <1.5% ( special needs can be <1.0% ) Operating pressure : 10g-100g ( tip or finger touch ) Glass thickness : 0.7mm, 1.1mm, 1.8mm, 3.0mm Glass Category: chemically strengthened glass , riot glass. Product Features Reliable, economical and practical, widely used. Able to identify any contact media such as a finger ( with gloves or without ) , pens , credit cards and other input signals. Lead using FPC ( flexible printed circuit board material ) is smaller than the resistance of PET material used by other manufacturers value , good flexibility . Line insulation little visual effect, now we can do the minimum insulation point ? 0.035mm, far ahead of other vendors . Touch screen surface shiny , matte, anti-glare variety of materials , matting , anti-Newton ring and process for selection Package Includes: 1 x Resistive touch screen for 7 inch LCD Monitor for Raspberry Pi 1 x Drive Module 1 x USB Cable Note: This listing is not included the 7 inch lcd monitor display for raspberry pi
