US Patent 11073941 Driving device and operation method thereof

A driving device and an operation method thereof are provided. The driving device is configured to drive a self-emissive display panel (e.g., an organic light emitting diode (OLED) display panel). The self-emissive display panel is an in-cell touch panel. The driving device includes a driving circuit and a control circuit. The driving circuit is configured to drive a plurality of pixel circuits of the self-emissive display panel during a first sub-period of a frame period to display an image frame. The control circuit is configured to control the driving circuit to set the pixel circuits not to emit light during a second sub-period of the same frame period. The control circuit performs a touch detection operation on the self-emissive display panel during the same second sub-period.
