  • Display device, display driving integrated circuit, and operation method
    Patent number: 11915666
    Abstract: A display device, a display driving integrated circuit (DDIC), and an operation method are provided. The display device includes a display panel, a first DDIC, and a second DDIC. The first DDIC generates a display synchronization signal, and drives a first display area of a display panel according to the display synchronization signal. The second DDIC is coupled to the first DDIC to receive the display synchronization signal. The second DDIC performs a frequency tracking operation on an internal clock signal of the second DDIC by selectively using the display synchronization signal. The second DDIC drives a second display area of the display panel according to the internal clock signal and the display synchronization signal.

  • Display apparatus and operation method for display panel thereof
    Patent number: 11062653
    Abstract: A display apparatus and an operation method for a display panel thereof are provided. The display apparatus includes a display panel and a voltage supply circuit. The display panel includes a pixel circuit and a common voltage line. The pixel circuit includes an organic light emitting diode (OLED), wherein a cathode of the OLED is coupled to the common voltage line. The voltage supply circuit is coupled to the common voltage line of the display panel. The voltage supply circuit supplies a common voltage to the common voltage line during a normal operation period. The voltage supply circuit supplies a reverse bias voltage higher than the common voltage to the common voltage line during a recovery period to reversely bias the OLED.
