Description

【Technical field】 [0001] The invention relates to a shift register circuit, in particular to a shift register circuit applicable to a touch display device. 【Background technique】 [0002] Liquid crystal display devices have the advantages of being light, thin and small, and have gradually replaced traditional bulky cathode ray tube (CRT) displays, and are widely used in various types of electronic products. With the miniaturization of the size of electronic products, there is not enough space on the products to accommodate traditional input devices such as keyboards and mice. Therefore, touch display devices that combine touch input and display functions are currently widely used in various formula products. There are many types of touch display devices, which are mainly classified into resistive, capacitive, ultrasonic and infrared sensing according to their touch sensing principles. When the touch panel touches, the touch position is obtained according to the sensed capa...
