How does a touchscreen work?
ProTech ::: Industrial WorkstationsThe touchscreen works just like a mouse. Instead of moving the mouse you move your finger or stylus across the screen and "drag" the cursor to where you need it. There are different types of touchscreens however they all basically work on an X and Y grid axis that detect where you are placing your finger. You can click or even double click simply by tapping the screen with your finger.
Related QuestionsFrequently Asked Questions - TechnicalA) A slight voltage is applied to four corners of the screen. Electrodes spread out the voltage, creating a uniform voltage field. When your finger makes contact with the screen's surface, it 'capacitively couples' with the voltage field, drawing a minute amount of current to the point of contact. The current flow from each corner of the screen is proportional to the distance to your finger.Related Questions
