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. | 10-07-2010 |
20100328333 | Power savings for display panels - In some embodiments one or more areas of interest to a user of a display screen are determined. Portions of the display screen other than the one or more areas of interest are dimmed. Other embodiments are described and claimed. | 12-30-2010 |
20110157212 | Techniques for adapting a color gamut - 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. | 06-30-2011 |
20110181611 | USER INTERFACE AND CONTROL OF SEGMENTED BACKLIGHT DISPLAY - In some embodiments a user interface is adapted to monitor user inputs and one or more controllers are adapted to modify backlight segment brightness and/or image pixel values of a segmented backlight display in response to the monitored user inputs. Other embodiments are described and claimed. | 07-28-2011 |
20130113694 | METHOD AND APPARATUS FOR ADAPTIVE BLACK FRAME INSERTION - 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. | 05-09-2013 |

20140292631 | BACKLIGHT MODULATION OVER EXTERNAL DISPLAY INTERFACES TO SAVE POWER - In general, in one aspect, an apparatus receives pixels associated with an image destined for an external display and determines a reduced backlight brightness for the external display and corresponding changes to the pixels to approximate overall quality of the image with current backlight brightness. Backlight commands are generated for the reduced backlight brightness and the pixels are enhanced to correspond to the reduced backlight brightness. The enhanced pixels and the backlight commands are transmitted to the external display via a display interface that supports backlight control. The display interface may be a wireless interface or a wired (cabled) interface (e.g., display port (DP), high definition multimedia interface (HDMI), video graphics array (VGA)). The functionality of the apparatus is included in a computing device so that backlight brightness reductions and corresponding pixel changes can be made taking into account policies of the computing device and user preferences. | 10-02-2014 |
