27 inch touch screen

27 inch touch screen.Four- and eight-wire touch screens can measure contact resistance, which is RTOUCH in Figure 5 . RTOUCH is approximately proportional to touch pressure. To measure touch pressure, you need to know the resistance of one or two layers in the touch screen. The formula in Figure 6 shows the calculation method. It should be noted that if the measured value of Z1 is close to or equal to 0 ( when the touch point is close to the grounded X bus during the measurement ) , some problems will occur in the calculation. This problem can be effectively improved by using a weak pull-up method.
