Touch recognition apparatus and method in capacitive touch screen
Abstract:
A touch recognition apparatus and method in a capacitive touch screen are provided. The touch recognition apparatus includes a touch panel and a controller. The touch panel includes a first sub panel and a second panel intersecting each other. The first sub panel includes a first electrode line and a second electrode line in X axis, and a plurality of resistors connected between the first electrode line and the second electrode line in X axis. The controller outputs scan signals to the first electrode line in X axis and the first electrode line in Y axis, receives scan sensing signals through the second electrode line in X axis and the second electrode line in Y axis, and measures delay times between the scan signals and the scan sensing signals to touched positions in X axis and Y axis, respectively.
