摘要： Techniques are described that can be used to provide color space conversion for images and video to a display color gamut space. Some techniques provide for accessing an sRGB gamut color table, determining a color conversion matrix based on the sRGB gamut color table and chromaticity values of RGBW primary and gamma stored in the display or associated with the display, applying color space conversion to the pixels for pixels using the color conversion matrix, and applying linear correction of pixels by applying a normalization factor to the color conversion matrix. In addition, some techniques provide analysis of content gamut with respect to display gamut in HSV space, adjustment in HSV space, and conversion back to RGB space before applying color space conversion.

摘要： In some embodiments, a display device may include a flat panel display a controller coupled to the flat panel display. The controller may be configured to determine an operating mode for the flat panel display among a plurality of operating modes including at least a first operating mode and a second operating mode. In the first operating mode, the controller may set the flat panel display to utilize a first frame rate and a first inversion mode to save power. In the second operating mode, the controller may set the flat panel display to utilize a second frame rate, a second inversion mode, and black frame insertion to improve image quality. The second frame rate may be faster than the first frame rate. The second inversion mode and black frame insertion may be mutually configured to maintain a DC balanced operation of the flat panel display. Other embodiments are disclosed and claimed.
