Abstract

The invention provides a touch display screen and a driving method of the touch display screen and relates to the field of display techniques. An interactive touch display screen capable of enabling a user to have touch sensation can be built. The touch display screen comprises a detection module, an conducting layer and a peripheral circuit, wherein the detection module is used for real-time detection of a current touch position, the conducting layer is arranged on the surface of a touch panel of the touch display screen and positioned in a display area of the touch panel, and the peripheral circuit is arranged in a non-display area of the touch panel, connected with the conducting layer, and load the conducting layer with a voltage, and a current is generated on a touch object contacting the touch display screen by the loaded voltage.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch display screen and a driving method thereof. Background technique [0002] With the development of thin film transistor liquid crystal display (Thin Film Transis tor-Liquid Crystal Display, TFT-LCD) technology and the progress of industrial technology, as well as the increasingly perfect manufacturing process of liquid crystal display devices, TFT-LCD display technology has replaced the cathode ray tube Display technology has become the mainstream technology in the field of flat panel display. Due to its own advantages, liquid crystal display has become an ideal display device in the minds of the market and consumers. [0003] With the rise of liquid crystal display in the field of mobile applications, interactive touch screen technology is increasingly favored by consumers, and has become an important technology and a new market growth point that coexists with liquid c...
