TOUCH DISPLAY APPARATUS SENSING MULTI TOUCH AND TOUCH FORCE AND DRIVING METHOD THEREOF

摘要

A touch display apparatus according to the present invention comprises a display panel and a touch screen panel disposed on an upper part of the display panel and simultaneously recognizing at least one touch. The touch screen panel includes a touch substrate, a first angle sensor, a second angle sensor, a force sensor and an arithmetic unit. Each of the first and second angle sensors senses a first touch angle and a second touch angle of the touch. The force sensor calculates a touch distance and a sensor force. The arithmetic unit calculates touch coordinates and touch forces based on the first touch angle, the second touch angle, the touch distance, and the sensor force.
