32 inch touch screen monitors

32 inch touch screen monitors.In order to measure a coordinate in a specific direction on a resistive touch screen, a resistive layer needs to be biased: one side of it is connected to VREF and the other side is grounded. At the same time, connect the unbiased layer to the high impedance input of an ADC . When the pressure on the touch screen is large enough to make contact between the two layers, the resistive surface is separated into two resistors. Their resistance is proportional to the distance from the touch point to the offset edge. The resistance between the touch point and the ground is equivalent to the lower resistance in the voltage divider. Therefore, the voltage measured on the unbiased layer is proportional to the distance from the touch point to the ground edge.
