LCD触摸显示屏控制定位系统:LCD触摸屏也变得普及，并逐渐成为当今的主流配置。触摸屏分为电阻、电容、表面声波、红外线扫描和矢量压力传感触摸屏等，其中使用最多的是四线或五线电阻触摸屏。四线电阻触摸屏是由两个透明电阻膜构成的，在它的水平和垂直电阻网上施加电压，就可通过A/D转换面板在触点测量出电压，从而对应出坐标值。-LCD touch screen control positioning system: LCD touch screen has become popular, and has gradually become the mainstream of today s configuration. Touch screen is divided into resistors, capacitors, surface acoustic wave, infrared scanning and vector pressure sensor touch screens, which use the most is the four-or five-wire resistive touch screen. Four-wire resistive touch screen is made up of two transparent membrane consisting of resistance, in its horizontal and vertical line resistance imposed voltage, can be through the A/D conversion panel measured in the contact voltage, which corresponds to the coordinate values.
