Abstract

The invention discloses a touch display screen and a manufacture method thereof, relating to the field of liquid crystal display and solving the technical problems of high manufacture cost because two screens need to be manufactured for the touch display screen. The touch display screen comprises a color film substrate and an array substrate arranged corresponding to the color film substrate, wherein the color film substrate comprises an upper substrate and a common electrode formed on the upper substrate; the array substrate comprises a lower substrate and a grid line, a data link and a pixel electrode which are formed on the lower substrate; the common electrode is provided with a plurality of spacers which butt against the grid line or the data link and enables the common electrode to be respectively electrically conducted with the grid line and the data line under the action of pressure; the touch display screen also comprises a voltage detection circuit; the voltage detection circuit is connected with the grid line and the data line and is used for detecting whether voltages on the grid line and the data line are equal to the voltage of the common electrode or not. The invention is applied to the touch display screen of a liquid crystal display.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a touch display screen and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (LCD) technology has developed rapidly in the past ten years, and great progress has been made in terms of screen size and display quality. LCD has the characteristics of small size, low power consumption, and no radiation. It has now occupied a dominant position in the field of flat-panel display. [0003] With the continuous expansion of LCD production, the competition among manufacturers is becoming increasingly fierce. While continuously improving product performance, various manufacturers are also making continuous efforts to reduce product production costs, thereby enhancing market competitiveness. [0004] The touch screen is one of the important carriers for integrating input and output terminals. Demand for touchscreen displays has exploded in recent ye...
