A touch display comprises a color filter substrate, an array substrate opposite to the color filter via a plurality of spacers and a voltage detection circuit. The color filter substrate comprises an upper substrate and a common electrode formed on the upper substrate, and the array substrate comprises a lower substrate and a gate line, a data line and a pixel electrode formed on the lower substrate. The plurality of spacers comprise a first spacer formed between the gate line and the common electrode and a second spacer formed between the data line and the common electrode, which are capable of electrically connecting the common electrode with the gate line and the data line respectively under an external pressure more than a threshold value. The voltage detection circuit is connected with the gate line and the data line so as to detect whether the voltage on the gate line and the voltage on the data line become equal to the voltage of the common electrode.
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...
