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.

A system for rendering color images on an electro-optic display when the electro-optic display has a color gamut with a limited palette of primary colors, and/or the gamut is poorly structured (i.e., not a spheroid or obloid). The system uses an iterative process to identify the best color for a given pixel from a palette that is modified to diffuse the color error over the entire electro-optic display. The system additionally accounts for variations in color that are caused by cross-talk between nearby pixels.

A method for display-brightness adjustment and related products is for an electronic device. The electronic device includes a screen and a distributed processing unit (DPU), the DPU includes hardware of N layers and a layer mix, and the hardware of N layers includes hardware of a first layer and hardware of M second layer, N being an integer greater than 1, M<N, and each of the hardware of N layers being coupled with the layer mix. The method includes the following. Backlight brightness of the screen is set to a first threshold in response to detecting an adjustment instruction for the backlight brightness of the screen. The first layer is modified to decrease brightness of the first layer. A third layer is obtained by superimposing a modified first layer and multiple second layer. Display the third layer on the screen.

A display device including a display panel including a plurality of pixels, and a driver configured to drive the display panel. The driver includes a dither configured to perform a dithering operation on image data including a plurality of pixel data for the plurality of pixels to generate dithered image data including a plurality of dithered pixel data respectively corresponding to the plurality of pixel data, and a still image detector configured to receive the dithered image data, to detect dither-irrelevant pixel data that are not changed from the plurality of pixel data by the dithering operation among the plurality of dithered pixel data, and to determine whether the dithered image data represent a still image by using the dither-irrelevant pixel data.

A display device includes a display panel and a panel driving block that controls driving of the display panel. The panel driving block includes a dithering judgment block, a memory, and a dithering compensation block. The dithering judgment block determines whether a first sub-image signal corresponding to a first image requiring dithering is included in the input image signal. The dithering compensation block reads out dithering patterns, which correspond to the first sub-image signal, from among the plurality of dithering patterns from the memory, generates a compensation dithering pattern by the read dithering patterns and a random number table, and outputs a correction image signal through the first sub-image signal and the compensation dithering pattern. The first image is displayed in a stain area, and the stain area includes at least one unit area.
