Abstract: A first driver circuit is configured to cooperate with a second driver circuit to control a display panel, wherein the first driver circuit is configured to output display data to a first area of the display panel and the second driver circuit is configured to output display data to a second area of the display panel. A method used for the first driver circuit includes outputting at least one emission control signal to control the second area of the display panel when the second driver circuit is disabled.

Abstract: An organic light-emitting display (OLED) panel, including an OLED layer, a touch sensing layer, and a shielding layer, is provided. The OLED layer is suitable for displaying an image. The touch sensing layer is suitable for sensing a touch event of the OLED panel. The shielding layer is disposed between the OLED layer and the touch sensing layer. The shielding layer is suitable for blocking a mutual interference between the OLED layer and the touch sensing layer.

Abstract: A display apparatus and a control device and a control method thereof are provided. A controller of the control device controls a gate driver of a display panel. The controller selects a first selected frame and a second selected frame in each frame group, wherein an adjacent position between a first partition and a second partition of the display panel corresponds to a corresponding time point in each frame of the first selected frame and the second selected frame. The controller transmits a reset pulse to the first gate driver at the corresponding time point in the second selected frame to clear a scanning pulse in the gate driver, and cancels the reset pulse at the corresponding time point in the first selected frame. Thus, the control device enables different display partitions of the display panel to have different frame rates or refresh rates.
