摘要： A stylus (100), a touch panel (200), a display device and a touch sensing method are provided. The stylus (100) includes: a first emitting electrode (12); a second emitting electrode (13), wherein a distance between the first emitting electrode (12) and the second emitting electrode (13) in an extension direction of the stylus (100) is greater than zero; and an emitting circuit (11), which is connected to the first emitting electrode (12) and the second emitting electrode (13), respectively. The emitting circuit (11) is used to emit a first electrical signal outwards through the first emitting electrode (12) and to emit a second electrical signal outwards through the second emitting electrode (13), so that the touch panel (200) determines a tilt angle (A1) of the stylus (100) relative to the touch panel (200) according to the received first and second electrical signals.

摘要： The embodiments of the application disclose a control device for a gate driving circuit, a display panel and a display device. The control device for a gate driving circuit provided in the embodiment comprises a level shifter and a control module electrically connected with an output of the level shifter. The control module is used for controlling an output signal of the level shifter to be a low level signal when each input clock signal for the level shifter is low.

摘要： A driving circuit for a touch screen, an in-cell touch screen and a display apparatus. A timing controller of the driving circuit controls a power supply circuit to output a clock signal with a first amplitude to an (N+1−n)th-stage to an Nth-stage shift registers (SR(n)) in a first time period at a display stage, and controls the power supply circuit to output a clock signal with a second amplitude to each stage of shift register (SR(n)) in a second time period at the display stage; and then levels of scanning signals output by the (N+1−n)th-stage to the Nth-stage shift registers (SR(n)) are higher than levels of scanning signals output by other stages of shift registers (SR(n)).
