  • Patent number: 9997115
    Abstract: An electrophoretic display apparatus and an image processing method thereof are provided. The electrophoretic display apparatus includes a display panel and a display driver. The display driver is configured to determine whether a plurality of pixel data of an image signal needs to being recoded according to one or more judgment conditions. If so, the pixel data is recoded. The display driver drives the display panel by using a plurality of driving signals having different signal waveforms, so that the display panel displays an image frame according to pixel data without being recoded and the recoded pixel data.

  • Publication number: 20180158392
    Abstract: A timing controller circuit of an electronic paper display apparatus including an image processing circuit and a timing controller is provided. The image processing circuit receives an image signal and analyzes the image signal according to a signal component of the image signal, so as to determine a display mode of the electronic paper display apparatus. The image processing circuit selects a driving signal waveform according to the determined display mode. The timing controller is electrically connected to the image processing circuit. The timing controller outputs the selected driving signal waveform to drive an electronic paper display panel of the electronic paper display apparatus to display image frames.

  • Patent number: 9972254
    Abstract: A color electrophoretic display apparatus and a display driving method thereof are provided. The color electrophoretic display apparatus includes a display panel and a display driver. The display panel includes a plurality of pixels. The display driver is electrically connected to the display panel and configured to drive the display panel to display one of a plurality of colors by using a plurality of driving signals having different waveforms. The driving signals include a first driving signal and a second driving signal. The display driver selects the first driving signal or the second driving signal according to image data, and drives at least one pixel of the display panel by using the first driving signal or the second driving signal, such that the at least one pixel displays one of black color and a plurality of gray colors with different gray values in the plurality of colors.
