Benefits of technology

The present invention is a touch screen display device that improves touch sensitivity by boosting the touch driving signal. This means that the device can detect touch more accurately and easily. The technical effect of this invention is improved touch sensitivity.

Problems solved by technology

However, the method described above requires a process of forming the touch sensor separately from the display device, and therefore, it is inefficient in terms of process time and process cost.

Abstract

A touch screen display device includes a first touch electrode, a second touch electrode and a conductive pattern. The first touch electrode receives a touch driving signal. The second touch electrode is positioned so as to be spaced apart from the first touch electrode. The conductive pattern is positioned so as to overlap with the first touch electrode, and receives a boost signal for boosting the touch driving signal. Accordingly, the touch driving signal is boosted, thereby improving touch sensitivity.

Description

CLAIM OF PRIORITY[0001]This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. 119 from an application for TOUCH SCREEN DISPLAY DEVICE earlier filed in Korean Intellectual Property Office on 30 Jan. 2013 and there duly assigned Serial No. 10-2013-0010522.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a touch screen display device, and more particularly, to a touch screen display device capable of improving touch sensitivity.[0004]2. Description of the Related Art[0005]A touch screen display device is a device that displays a screen and receives a user's command by recognizing contact of a hand or object with the screen.[0006]Since the touch screen display device does not require a separate input device such as a keyboard or mouse, its application fields have been gradually extended.[0007]Conventionally, the touch screen display device was manufactured using a method of separ...
