METHOD AND DEVICE FOR PROVIDING AN EQUI-POTENTIAL TOUCH SCREEN

摘要

Disclosed is a method (50) and device (100) for providing an equi-potential touch screen. The method can include: providing (52) a capacitive touch screen including transmit electrodes and receive electrodes combined to form a grid structure configured to provide capacitive signals that allow position of touch to be resolved; and driving (54) a substantially central transmit electrode with equi-potential connection points. The method (50) and device (100) provide a touch screen device which allows drive lines to be split on either side of the touch screen device, while being highly linear. For example, the frame area surrounding the touch screen can be made narrower or thinner, for minimal real estate and optimizing design layout.
