A driving method includes: receiving a frequency modulation signal; generating a frequency modulation synchronization signal; generating an auxiliary synchronization signal when a rising edge of the frequency modulation synchronization signal is in a writing phase of a light-emitting unit group to which light-emitting data signals are last written in a previous frame period; and controlling, based on the auxiliary synchronization signal, a writing phase of a light-emitting unit group to which light-emitting data signals are to be first written in a current frame period to be staggered with the writing phase of the light-emitting unit group to which light-emitting data signals are last written in the previous frame period. The light-emitting unit group to which light-emitting data signals are last written in the previous frame period belongs to same cluster as the light-emitting unit group to which light-emitting data signals are to be first written in the current frame period.

The present application discloses a touch sensing apparatus. The touch sensing apparatus includes a plurality of magnetic sensor units spaced apart from each other, each of which configured to detect a change in magnetic field caused by a first touch input and connected to a first touch integrated circuit. Each of the plurality of magnetic sensor units includes a reference conductor and a plurality of conductors surrounding the reference conductor, the reference conductor and each of the plurality of conductors independently connected to the first touch integrated circuit. The first touch integrated circuit is configured to determine a touch position of based on changes in capacitances between the magnetic sensor and each of the plurality of conductors.

Touch sensing apparatus, touch control display panel, touch control display apparatus, and touch sensing method including magnetic sensor units

A display screen, a touch pen and a display module are disclosed. The display screen includes a frame, a touch display panel, a controller and a plurality of sound wave detectors; the plurality of sound wave detectors are disposed at different positions on the frame and at the same side of frame as an operating surface of the touch display panel. Sound wave detector detects sound wave signals sent by sound wave emission sources and sends the detected sound wave signals to the controller; the touch display panel detects electromagnetic signals sent by electromagnetic generators and sends them to the controller; the controller determines actual touch positions of a plurality of touch pens on the touch display panel based on the electromagnetic signals and sound wave signals emitted by sound wave emission sources of the touch pens to achieve accurate positioning.
