Abstract

The invention discloses a sensing display device and a shift register thereof. The sensing display device comprises a time schedule controller, a sensing driver, and a scanning driver. The scanning driver is provided with multiple stages of shift temporary registers. Each shift temporary register is provided with a driving unit, a pull-up unit, a pull-down control unit, a discharging unit, and a pull-down unit. The discharging unit regulates the voltage level of a driving node according to a first control signal and a first scanning signal. A clock signal and the first control signal are same-phase periodic signals and are provided with rising edges and falling edges. The falling edge of the first control signal is prior to that of the clock signal. The pull-down unit regulates the voltage level of an output end according to a second control signal. The first control signal and the second control signal are pull-down unit periodic signals. After a shift temporary storage circuit stops, the voltage level of an internal node can be stilled charged to a driving circuit with a preset voltage level in order to prevent the internal nodes of the shift temporary storage circuit from generating electric leakage, prevent incorrect display, and output correct waveforms.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a sensing display device and a shift register thereof. Background technique [0002] Recently, various liquid crystal display products have been widely used in mobile handheld devices. And due to the wide application of smart terminal devices, the integration of touch functions into smart terminal devices has become the mainstream demand of today's products, such as general smart terminal devices. [0003] Please refer to figure 1 , the existing smart terminal device with touch display function will start the touch driver for touch driving during the display pause period, such as figure 1 as shown, figure 1 It is a waveform schematic diagram of an existing shift register with a touch display function. The display panel has multiple scan lines, and the scan driver includes a multi-level shift register circuit. The clock signal CK and the scan signal G(n-1) , G(n), and driving...
