Working Principle
When users press he surface of the panel,the digital type responses with only ON/OFF signals;
however,compare with analog type,the linearity has no significant relation with it.Therefore,the
demand of material and technology for digital type is muchlower than that of analog type.
During processing,the unused portions of the upper and lower electrodes are etched out respectively.
Conductive line is pulled out from every vertical and horizon layout,user only needs to press the
correspondent area to connect the upper and lowerelectrodes,the LCD panel will display informationaccordingly.
