Abstract: The disclosure provides a driving device for a self-luminous display panel and an operation method thereof. The driving device includes multiple GAMMA voltage circuits, a group of driving channels, and a routing circuit. Each driving channel is coupled to the corresponding GAMMA voltage circuit to receive a corresponding group of GAMMA voltages. Each driving channel converts corresponding sub-pixel data into a corresponding gray scale voltage based on the corresponding group of GAMMA voltages. The routing circuit is coupled to the output terminals of the driving channels. The routing circuit dynamically changes the coupling relationship between the driving channels and multiple data lines of the self-luminous display panel during different scanning periods.

Abstract: A knob apparatus includes a touch panel, a touch-sensing controller, and a knob. The touch panel has multiple touch-sensing electrodes. The touch-sensing controller is coupled to the touch-sensing electrodes of the touch panel. The touch-sensing controller detects a touch event of the touch panel through the touch-sensing electrodes. The knob has a base and a knob cap. The knob cap is pivoted on the base. The base is attached to the touch panel. Multiple conductive electrodes are disposed at different positions of the base. The touch-sensing controller detects the conductive electrodes of the base of the knob through the touch-sensing electrodes of the touch panel to learn a rotation direction of the knob cap on the base.

Abstract: A power converter includes a high side switch, a low side switch, a low side driver, a loading detector, a configurable regulator and a high side driver. The low side driver generates a low side drive signal to control the low side switch. The configurable regulator generates a regulation voltage, a magnitude of which is greater when the loading detector detects that the power converter has light loading than when the loading detector detects that the power converter has heavy loading. The high side driver generates a high side drive signal that switches between the input voltage and the regulation voltage to control the high side switch.

Abstract: A driver circuit suitable driving a display panel is provided. The driver circuit includes a display driver circuit and a touch driver circuit. The display driver circuit drives the display panel to be operated in a first mode or a second mode. In the first mode, different areas of the display panel have different frame rates. In the second mode, different areas of the display panel have a same frame rate. The touch driver circuit is coupled to the display driver circuit. The touch driver circuit detects a touch event. When the touch driver circuit detects the touch event, the display driver circuit drives the display panel to be switched from the first mode to the second mode.
