Abstract: A field-sequential display is operated in one of a color mode or a grayscale mode. In the color mode, a video source provides image content in the form of multiple-color image data having a frame rate of X Hz and a display controller uses the multiple-color image data to drive the field-sequential display so as provide multiple-color image content at the field-sequential display. In the grayscale mode, the display controller generates grayscale image data from the multiple-color image data and the display controller then drives the field-sequential display with the grayscale image data at a lower frame rate of Y Hz. While in the grayscale mode, the display controller can take advantage of the enhanced contrast provided by the grayscale image content to reduce or disable backlighting at the field-sequential display. The reduced timing requirements afforded by the lower frame rate, as well as the reduction or elimination of backlighting, can reduce power consumption compared to the color mode.

Abstract: A system and method that allows a LED driver board to both traverse the full width of the LCD glass and not occupy the volume occupied by hinges of the notebook information handling system. By providing an LCD display assembly that includes an LED backlight illumination system, the LED driver board for a panel may be moved to the bottom side of a display assembly.

Abstract: Image quality and power management associated with a LCD panel are balanced with selective enabling and disabling of response time compensation to selection of liquid crystal material states. A power manager disables overdrive voltages for response time compensation with one or more predetermined conditions, such as reliance on internal power or display of non-moving graphics, and enables overdrive voltages with other predetermined conditions, such as reliance on external power or display of moving graphics. Selective enabling and disabling of response time compensation for setting liquid crystal material states ensures highest quality video graphics with appropriate images while reducing unnecessary power consumption when high quality video graphics provide less benefit, such as with lower quality images.

Abstract: An information handling system display presents multimedia visual information with plural performance settings based on the type of image associated with the visual information. For instance, an image detector detects plural types of images so that a display controller automatically applies color and brightness settings associated with the type of detected image. Flash memory stores the sets of performance settings for use by the display controller as different types of images are detected, such as movie images, picture images, game images and text images.

Abstract: A method and system selects between a LED light source and an electroflorescent light source, such as a CCFL light source, to illuminate a LCD panel that displays information generated by an information handling system. A light source controller selects one or both of LED and CCFL light sources to illuminate the LCD panel based on one or more predetermined factors, such as the power consumption of the light source for a selected display brightness. In one embodiment, the light source controller preserves battery power of a portable information handling system by selection of one of the light sources based on a determination of which light source will consume the least power for a selected display brightness level.
