Abstract

A touch panel apparatus and method for controlling the same. The touch panel apparatus includes a touch panel for recognizing a contact position and a touch panel controller for computing a coordinate value corresponding to the contact position on the touch panel, wherein an activation force is set to a value between 80 g~150 g, and the touch panel controller compensates for an error of the coordinate value due to double touching of the touch panel.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel device and a method for controlling the touch panel device. The control method can prevent touch errors caused by double touching. Background technique [0002] Displays that display graphics include cathode ray tubes, liquid crystal displays, plasma display panels, and electroluminescent displays. In order to easily input information on the screen, a display is used as an input means that if the user presses the screen surface with a pen or finger, information is input by setting a touch pad on the screen surface corresponding to the touched position. [0003] FIG. 1 shows a touch panel device according to the prior art. With reference to Fig. 1, conventional touch panel device comprises: touch panel 10, is used to provide the coordinate signal of touch point; Coordinate values ​​are calculated and provided to system 40 . [0004] The touch panel 10 includes: an upper fi...
