    Abstract: A driving device, an operation method thereof, and a display apparatus are disclosed. The driving device is configured to drive a display panel. The driving device divides an image frame period into a plurality of sub-frame periods. A target pixel circuit in the display panel corresponds to target pixel data comprising at least one bit. Each bit in the target pixel data corresponds to at least one corresponding sub-frame period among the sub-frame periods. Different bits in the target pixel data correspond to different sub-frame periods among the sub-frame periods. According to a current bit in the target pixel data, the driving device determines whether to light up the target pixel circuit during the at least one corresponding sub-frame period corresponding to the current bit.

    Abstract: A display driver integrated circuit, an image processor, and an operation method thereof are provided. The display driver integrated circuit includes a receiving circuit, a memory unit, and a foveated rendering circuit. The receiving circuit receives a first image and a second image from an image providing circuit. The memory unit stores the first image and the second image.
    The foveated rendering circuit is coupled to the memory unit. The foveated rendering circuit generates an output image to be displayed by performing image processing based on the first image and the second image. The first image is with respect to a foveated area of the output image. The receiving circuit receives at least a part of one of the first image and the second image before the other one of the first image and the second image is completely received.

    Abstract: A driving device and an operation method thereof are provided. The driving device drives a plurality of light-emitting control lines of an organic light emitting diode (OLED) display panel. The light-emitting control lines are divided into a plurality of groups. The driving device includes a control circuit and a plurality of logic gates. The control circuit generates a global light-emitting control signal and determines a duty cycle of the global light-emitting control signal. Any one of the logic gates determines whether to transmit the global light-emitting control signal to the light-emitting control lines of a corresponding group among the groups. When the global light-emitting control signal is transmitted to a corresponding light-emitting control line among the light-emitting control lines, a pulse of the global light-emitting control signal may light up a plurality of pixels connected to the corresponding light-emitting control line.
