20100085289 | GRAYSCALE-BASED FIELD-SEQUENTIAL DISPLAY FOR LOW POWER OPERATION - 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. | 04-08-2010 |

20140098027 | Systems and Methods for Locking Image Orientation - An information handling system includes a housing, a processor, memory, and a touch screen display that has a display portion operable to present information as an image. The system also includes a touch controller and an orientation module. | 04-10-2014 |
20140153160 | Touch Panel Device and Method for Assembly of a Touch Panel Display - A method includes providing a touch panel interposer, where providing the touch panel interposer comprises providing a touch panel device, applying a first adhesive layer to a cover side of the touch panel device, and applying a second adhesive layer to a display side of the touch panel device. The method further includes providing a touch panel display, where providing the touch panel display comprises applying a cover to the first adhesive layer, and applying a display panel to the second adhesive layer. | 06-05-2014 |
20140176444 | METHOD AND SYSTEM FOR AUTO CALIBRATION OF DISPLAY USING AMBIENT LIGHT SENSORS - An information handling system having a first housing, a second housing interoperably coupled to the first housing and movable relative to the first housing between an open configuration and a closed configuration, and a sensor integrated with a housing of the first housing and the second housing. A display integrated with the same housing of the first housing and the second housing as the sensor and a light guide integrated with a different housing of the first housing and the second housing from the sensor, the light guide having an input and an output. In the closed configuration, the input faces a portion of the display and channels light having display attributes from the display to the output and the sensor is at least partially aligned with the output and receives at least some of the channeled light. | 06-26-2014 |
20140198084 | METHOD AND SYSTEM FOR DISPLAY BRIGHTNESS AND COLOR OPTIMIZATION - Systems and methods for display brightness and color optimization include detecting, by a sensor communicatively coupled to a display, a change in an environmental brightness level. Additionally, in response to the change in the environmental brightness level, modifying a brightness level of the display and modifying a color gamut available to the display. | 07-17-2014 |
20140204007 | METHOD AND SYSTEM FOR LIQUID CRYSTAL DISPLAY COLOR OPTIMIZATION WITH SUB-PIXEL OPENINGS - Systems and methods for liquid crystal display brightness and color optimization that includes configuring a sub-pixel of a LCD to allow light from a backlight to traverse the sub-pixel unfiltered to a display surface of the LCD. The method also includes determining a color primary based on the amount of light from the backlight that traverses the sub-pixel unfiltered. The color primary defines a portion of a color gamut available to the LCD, and the color gamut has a plurality of colors. The method further includes applying a color restoration algorithm to adjust the plurality of colors in the color gamut. | 07-24-2014 |

20090066873 | LCD Display with LED Backlight Optimized for Minimum Notebook Computer Dimensions - 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. | 03-12-2009 |
20130278614 | Information Handling System Display Adaptive Self-Refresh - Information presented as images at a display are provided by a panel self-refresh module of the display instead of a graphics system, with the panel self-refresh module using a reduced refresh rate of the image to reduce power consumption. During a panel self-refresh mode, brightness of an image presented at the display is managed locally at the display to support power down of a graphics system interfaced with the display. | 10-24-2013 |
20130342473 | Multi-Zone Touchscreen Orientation - A tablet portable information handling system touch screen display includes a touch surface that extends past the periphery of a display surface to accept touch inputs used to establish an orientation of images presented at the display surface. For example, thumb and palm touches at the touch surface outside the periphery of the display are analyzed to determine the orientation of the tablet information handling system so that images presented at the display align with the determined orientation. | 12-26-2013 |
20130342474 | Multi-Zone Touchscreen Sensing At A Portable Information Handling System - An information handling system includes a touch screen with a first zone disposed over a display and a second zone that extends past a periphery of the display. End users interact with an operating system and applications of the information handling system with touches input in the first zone responsive to images presented at the display. End users perform management functions with touches input in the second zone independent of images presented at the display. | 12-26-2013 |
