四线触摸显现屏包罗两个阻性层。此中一层在屏幕的摆布边缘各有一条垂直总线，另外一层在屏幕的底部和顶部各有一💞条程度总线，见图4。为了在X轴标的目的停止丈量，将左边总线偏置为0V，右边总线偏置为VREF。将顶部或底部总线毗连到ADC，当顶层和底层相打仗时便可作一次丈量。

　　为(wei)了让在Y轴标(biao)原(yuan)因中止仗量，将(jiang)表层数(shu)据(ju)串(chuan)(chuan)(chuan)口通(tong)信(xin)(xin)(xin)偏置(zhi)(zhi)(zhi)为(wei)VREF，底数(shu)据(ju)串(chuan)(chuan)(chuan)口通(tong)信(xin)(xin)♓(xin)偏置(zhi)(zhi)(zhi)为(wei)0V。将(jiang)ADC打出(chu)端接(jie)右(you)侧(ce)数(shu)据(j🎉u)串(chuan)(chuan)(chuan)口通(tong)信(xin)(xin)(xin)或右(you)下方数(shu)据(ju)串(chuan)(chuan)(chuan)口通(tong)信(xin)(xin)(xin)，当楼房顶层与框架相(xiang)发动(dong)战争时(shi)便可对(dui)电压(ya)降中止仗量。图(tu)5显(xian)露了四线触控(kong)显(xian)露屏(ping)在二屋(wu)相(xiang)发动(dong)战争时(shi)的简单化模貝。对(dui)四线触控(kong)显(xian)露屏(ping)，最(zui)实现的毗(pi)连方式英文是将(jiang)偏置(zhi)(zhi)(zhi)为(wei)VREF的数(shu)据(ju)串(chuan)(chuan)(chuan)口通(tong)信(xin)(xin)(xin)接(jie)ADC的正选(xuan)取(qu)打出(chu)端，并将(jiang)布置(zhi)(zhi)(zhi)为(wei)0V的数(shu)据(ju)串(chuan)(chuan)(chuan)口通(tong)信(xin)(xin)(xin)接(jie)ADC的负选(xuan)取(qu)打出(chu)端。
