Abstract

Provided are a touch panel device and a method of controlling the same, the touch panel device comprising: a touch panel for identifying a contact position; and a touch panel controller for calculating a coordinate value corresponding to the contact position on the touch panel , where the trigger force is set to a value between 80g and 150g, and the touch panel controller compensates for the coordinate value error caused by the double touch 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...
