摘要： Methods, systems and apparatuses may provide for technology that generates a seed value, wherein the seed value is dedicated to a position of an input pixel, generates a dithered pixel value based on the seed value and a value of the input pixel, and conducts a scan-out of the dithered pixel value to a display panel. In one example, the technology generates an intermediate value based on the seed value and one or more fixed constants and generates a pseudo random number based on the intermediate value and a programmable constant, wherein the dithered pixel value is generated based on the pseudo random number and the value of the input pixel.

摘要： If the picture complexity is low then the number of pixels in a frame may be reduced. For example, pixel-to-pixel variation in terms of RGB color values can be used to determine the complexity of the frame. Frames can be characterized, in one embodiment, as non-complex frames with less pixel variation and complex frames with very high pixel variation. The high PPI may be used only for complex frames while non-complex frames can use low PPI. This method reduces memory fetching and pixel processing within the display engine and thereby saves power.

摘要： Methods, apparatus, and articles of manufacture to provide extended graphics processing capabilities are disclosed. A disclosed example method involves sending a display panel parameter to a shared library module. The display panel parameter is sent by a programmable driver interface in communication between the shared library module and a graphics hardware device driver. The shared library module includes a first graphics processing capability. The graphics hardware device driver includes a second graphics processing capability different from the first graphics processing capability. The example method also involves performing a render operation via the programmable driver interface on a frame buffer based on the first graphics processing capability. The first graphics processing capability is received at the programmable driver interface from the shared library module based on the display panel parameter. The frame buffer is output to a display.

摘要： A number of frames may be transferred in one frame period to a display panel followed by at least one frame period during which no frame is transferred. During this link idle time, the display panel continues to work on the transferred frames. However, the link and/or graphics processor may be powered down during this time to reduce power consumption.

摘要： By converting a first color space to a second color space, using a two-dimensional lookup table in said second color space, and converting from said second color space to said first color space, it may be possible to use one or more two-dimensional lookup tables (LUTs) to do a task conventionally handled by three-dimensional lookup tables. This may reduce storage requirements and memory bandwidth requirements in some embodiments. In general a color pixel with N color components can be processed with n number of M dimensional LUT where M
