Touch Screen LCD Monitor
① They are completely isolated from the outside world of a working environment, not afraid of dust, water vapor and oil
② can use any object to touch, can be used to write to draw, it is their relatively large advantage
③ resistive touch screen accuracy depends only on A / D conversion accuracy, it can easily reach 4096 * 4096 ? Comparatively
speaking, the five-wire resistive 4-wire resistive than the accuracy but also in ensuring superior resolution, but the costs
are large, Therefore, price is very high.http://www.global-
4-wire resistive analog technology, the work of two transparent metal layer and each layer had increased 5V constant voltage:
a vertical direction, a horizontal direction. A total of four cables required. Features: High-resolution, high-speed
response. Surface hardness treatment, to reduce abrasion, scratch and anti-chemical treatment. With a smooth and matte
handle. Time correction, high stability, and never drift.

5-wire resistive touch screen technology, http://www.global-
resistor networks are added to the work of conductive glass surface, we can simply be understood as the voltage field in both
directions of staggered working hours added to the same work surface, The outer layer of Ni-Au conductive layer is only just
used as a pure conductor, there are time-test, after touching the inner ITO contact point X-axis and Y-axis voltage value
method measured touch point position. 5-wire resistive touch screen inner ITO need four-lead, only for the outer conductor is
only one, touch-screen had a total of 5 pinout. Features: high-resolution, high-speed transmission response. High surface
hardness, reduce abrasion, scratch and anti-chemical treatment. 30 million times with the point contact can still be used.
