The present disclosure relates to a driving method of graphene display device and the graphene display devices. The method includes obtaining target point coordinates of a pixel within a color gamut system by RGB grayscale values to be inputted by the pixels, obtaining chromaticity coordinate (CIE) or a brightness of a first dynamic sub-pixel and a second dynamic sub-pixel of the pixel according to a location relationship of three color gamut blocks divided by a RGB color gamut within the target point coordinate and a gamut coordinate system, determining a driving voltage of the pixel in accordance with the CIE or the brightness of the first dynamic sub-pixel and the second dynamic sub-pixel, and outputting the driving voltage to the pixel. The graphene display device may for quickly, effectively, and more convenient realize high color fidelity so as to enhance the performance of LCDs.

In an embodiment, a system includes a display processing unit configured to process a video sequence for a target display. In some embodiments, the display processing unit is configured to composite the frames from frames of the video sequence and one or more other image sources. The display processing unit may be configured to write the processed/composited frames to memory, and may also be configured to generate statistics over the frame data, where the generated statistics are usable to encode the frame in a video encoder. The display processing unit may be configured to write the generated statistics to memory, and the video encoder may be configured to read the statistics and the frames. The video encoder may be configured to encode the frame responsive to the statistics.

Systems and methods for compositing an image from display planes are disclosed. An internal matrix having transparency data indicating transparency of a macro block of a digital representation of a display is accessed. An external matrix is accessed if the internal matrix indicates the macro block includes a transparent and opaque pixel, wherein the external matrix has transparency data indicating transparency of each pixel in the macro block. A first display plane is read based on the transparency data indicating opaque pixels and the first display plane data is sent to a first buffer. Second display plane data of a second display plane is read and sent to a second buffer if the transparency data indicates transparent pixels. Control data is inserted into the first buffer accordingly such that an image is generated based on at least one of the first and second display plane data and the control data.

A system for normalizing, codifying categorizing divergent color systems into a universal color language. A server connected to a communications network receives, processes, codifies and categorizes divergent color data from a merchant system. A middleware engine of the server receives a data feed comprising a plurality of color swatches or images from the merchant system, and normalizes the data feed into a common format. A server processor extracts image data comprising a plurality of product images from the normalized data feed, identifies and converts at least one dominant product color in each product image to a digital value based on color component intensity values, and assigns a hexadecimal code of the universal color language to each product image that is closest to the digital value of each product image. A product categorization engine categorizes each product image into one of a plurality of product categories.

A display device includes a color transformer and an image controller. The color transformer receives and transforms a three-color image into a four-color image. The four-color image includes a red image, a green image, a blue image, and a white image. The image controller calculates decrement offsets of the red image, the green image, and the blue image, and a compensation value of the white image. The image controller calculates gray level values of the red image, the green image, and the blue image when a value of the white image is zero. The image controller respectively calculates a red image control signal, a green image control signal, and a blue image control signal based on the gray level values and the decrement offsets, and the image controller calculates a white image control signal based on the gray level values and the compensation value of the white image.

Sticking of a Pixel is suppressed to improve the life of a display panel. In an emission display apparatus with a display panel in which a plurality of pixels each having at least one subpixel are disposed. A first display method of emitting light with only a pixel P(i,j) serving as an emission center and a second display method of allocating luminance of the pixel P(i,j) serving as an emission center to nearby pixels surrounding the pixel are combined in a controllable manner. A high-resolution mode with a high ratio of the first display method and a long-life mode with a high ratio of the second display method are switched therebetween depending on a spatial change or time change of image input data, an emission time, a degradation rate, a temperature, an emission luminance, and a display time.

A set of pixels of a background element is identified according to a mask that defines a shape of a foreground element. A color value for a pixel of the foreground element is determined. The determining includes ascertaining a value of a measure of brightness of one or more pixels of a set of pixels of the background element and calculating the color value for the pixel of the foreground element based on the value of the measure of brightness and a value of an adjustable contrast variable. The calculating the color value for the pixel of the foreground element preserves in the foreground element a color component of the one or more pixels of the set of pixels of the background element and increases contrast with the value of the measure of brightness according to the value of the adjustable contrast variable.
