Method for detecting touch position of touch screen and touch screen using same |
摘要 |
Disclosed are a method for detecting a touch position of a touch screen and the touch screen using the same. A method for detecting a touch position on a touch screen includes the steps of: detecting a touched touch screen block among touch screen blocks by using signals generated from at least one touch sensor among touch sensors included in a plurality of touch screen blocks into which an area of the touch screen is divided; and detecting a touch position in the detected touch screen block on the basis of a signal of a touch sensor included in the detected touch screen block. Thus, compared to an existing method of processing a signal by reading measurement values of all measurement sensors, the invention enables fast signal processing, thereby reducing measurement signal processing time for measuring a touch position of a touch screen. |

1. A method for detecting a touch position on a touch screen, comprising:
detecting a touched touch screen block among touch screen blocks by using signals generated from at least one touch sensor among touch sensors included in a plurality of touch screen blocks into which an area of the touch screen is divided; and detecting a touch position in the detected touch screen block on the basis of a signal of a touch sensor included in the detected touch screen block, wherein the detecting of a touched touch screen block among touch screen blocks by using signals generated from at least one touch sensor among touch sensors included in a plurality of touch screen blocks into which an area of the touch screen is divided, comprises, if a touched touch screen block is detected by using signals generated from a plurality of touch sensors in one touch screen block among touch sensors included in the plurality of touch screen blocks: adding the signals generated from the plurality of touch sensors in each touch screen block through block switches; transmitting the signals added through the block switches to a signal processing controller through at least one channel switch that operates in synchronization with the block switches; and detecting a touched touch screen block among the touch screen blocks on the basis of the signals transmitted to the signal processing controller. |
