提出了一种五线电阻触摸屏的坐标定位方法。五线电阻触摸屏从下导电层的4个角施加恒定电流流入，所有电流从上导电层流出。定位触按坐标时，先设置初始预设点，然后测量触按点的实际对角线电压，采用反向搜索定位法，计算预设点和搜索点的理论对角线电压，取误差最小的理论对角线电压点为新预设点，反复搜索，最终逼近触按点。该方法解决了在不加补偿电极的情况下，五线电阻触摸屏的非线性方程求解和失真校正问题，可以使五线电阻触摸屏的边框变窄，拓宽了五线电阻触摸屏在小屏幕下的应用范围。

Puts forward a method on positioning coordinate of five-wire resistive touch screen. The constant current is applied to inflow from four corners of lower conducting layer of the resistive touch screen and all current outflows from upper conducting layer. Sets the initial preset point first when the touch coordinate is positioned, then measures the actual diagonal voltage of the touch point, and uses the reverse-search positioning method to calculate the theoretical diagonalvoltage of the preset and searching point. Takes the theoretical minimum error diagonal voltage point as new preset point and searches repeatedly to get the final approach touch point. The method solves the problems of nonlinear equa-tions solution and distortion calibration for five-wire resistive touch screen without the compensation electrode. It makes the touch screen frame narrower and broadens the five-wire resistive touch screen application range in small screen.
