                                                                                         Resistive screen performance characteristics

① They are all working environments that are completely isolated from the outside world, not afraid of dust, water vapor and oil pollution
②It can be touched with any object, and can be used to write and draw. This is their biggest advantage
③The accuracy of the resistive touch screen only depends on the accuracy of A/D conversion, so it can easily reach 4096*4096. Comparatively speaking, the five-wire resistor is superior to the four-wire resistor in ensuring the resolution accuracy, but the cost is high. So the price is very high.

basic concept
A resistive touch screen is a sensor that converts the physical location of a touch point (X,Y) in a rectangular area into a voltage representing the X and Y coordinates. Many LCD modules use resistive touch screens, which can use four, five, seven or eight wires to generate screen bias voltage and read back the voltage at the touch point at the same time.

The resistive touch screen is basically a structure of film and glass. The adjacent side of the film and glass is coated with ITO (Indium Tin Oxides, nano-indium tin metal oxide) coating. ITO has good conductivity and transparency. . When touch operation, the ITO on the lower layer of the film will touch the ITO on the upper layer of the glass, and the corresponding electrical signal will be transmitted through the sensor, sent to the processor through the conversion circuit, and converted into the X and Y values on the screen through calculation, and the point is completed. The selected action is displayed on the screen.
