Abstract

The invention provides a touch display module. A static electricity guide-out portion is arranged on a flexible circuit board of a touch display screen and is connected with a reflector plate, so that produced static electricity is guided out of the touch display module through the flexible circuit board, and under the situation of not using a backboard, the quality of the touch display module can be effectively ensured. In addition, according to the touch display module, a touch circuit is directly formed on a CF substrate of a display panel, the use frequency of the substrate of an existing touch tablet is reduced, the thickness of the touch display screen is decreased, and the touch display module is thinned. As an existing polarizer with the anti-static function is set to be a non-anti-static polarizer, the touch drifting phenomenon is prevented effectively while the cost is lowered.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a touch display module. Background technique [0002] With the development of display technology, touch display modules are more and more widely used in various devices with display functions. When the user approaches or touches the surface of the touch display screen of the touch display module with a finger or a conductive object, the touch position is sensed by the change of the internal circuit or capacitance of the touch display screen, and a response is made. A common touch display screen is usually a touch panel and a liquid crystal display screen bonded together to form a touch control display screen. [0003] Most of the touch display modules currently on the market are backlight touch display modules, which include a housing, a touch display screen disposed in the housing, and a backlight module disposed in the housing. [0004] see figure 1 , the existing touch display ...
