This invention relates to a resistive touch screen which can identify multi-touch points. The resistive touch screen is characterized by arranging first and second resistive detection patterns to be orthogonal to each other. Plural stripes in the patterns are arranged in parallel. Further, the invention is characterized by obtaining X and Y coordinates through alternate application of voltage to the stripes only related to the touched portion. Known devices only indentify one touch point, whereas this invention is able to identify multi-touch points which cannot be identified with conventional resistive touch screens. |
