The display device includes a display panel. The display driving method includes: detecting noise from the display panel to obtain an in-panel noise value; sending target uplink information to an active stylus pen based on the in-panel noise value, and receiving target downlink information returned by the active stylus pen under a target pen voltage based on the target uplink information; and the target downlink information including position information; determining a coordinate distance value between position coordinates based on coordinate information of the position coordinates of the position information; and reporting contact information of the active stylus pen generated on the display panel at a target report rate based on the coordinate distance value.

Display driving method with target report rate

The present application provides a display device, a driving method thereof, and an active stylus thereof. The display device uses a second time section to transmit display data, uses a first time section and a third time section to transmit uplink signals with a lower anti-interference ability, and simultaneously adjusts a data transmission sequence of the active stylus and uses the third time section to transmit first touch data with a lower anti-interference ability to prevent interference of the display noise with the data of the active stylus and improve a recognition rate of touch data of the active stylus.

Display device, driving method thereof, and active stylus thereof

The present application provides a touch panel and a touch device. The touch panel comprises first channels and third channels that extend in a first direction and are arranged side by side. By reducing a distance between the third channel and the adjacent first channel, a touch sensing amount of the third channel is increased, and touch operations have improved accuracy and linearity in an edge area.

Touch panel and touch device

Embodiments of the present disclosure provide a display panel and a display device, the display panel forms multiplexing electrodes on a common electrode layer, and the multiplexing electrodes can transmit a common signal and a touch signal, a function of the common electrodes and a touch function are realized, parasitic capacitances between the touch electrodes and the common electrodes are eliminated, and the display effect and the touch effect are improved, and by using the power management chip to connect to the multiplexing electrodes, the signal input to the multiplexing electrode can be realized, and a function of the multiplexing electrodes can be realized.
