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. | 10-07-2010 |
20110157198 | Techniques for aligning frame data - Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques are useful to avoid visual distortions when changing from a first video source to a second video source. | 06-30-2011 |
20110157202 | Techniques for aligning frame data - Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques attempt to avoid visible glitches when switching from displaying a frame from a first source to displaying frames from a second source even though alignment is achieved by switching if frames that are to be displayed from the second source are similar to those displayed from the first source. | 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 |
20110196998 | PROTOCOL EXTENSIONS IN A DISPLAY PORT COMPATIBLE INTERFACE - A computer can control a target device using a packet format described herein. In one example, an extension packet controls the target device in at least one of power consumption, image rendering, and register updating. | 08-11-2011 |
20120075188 | TECHNIQUES TO CONTROL DISPLAY ACTIVITY - Techniques are described to transmit commands to a display device during vertical or horizontal blanking intervals. The commands can be transmitted using fields that would otherwise be used to transmit color information. A Low Voltage Differential Signaling (LVDS) compliant interface can be used to transmit the commands. | 03-29-2012 |
20120079295 | TECHNIQUES TO TRANSMIT COMMANDS TO A TARGET DEVICE - Techniques are described to transmit commands to a display device. The commands can be transmitted in header byte fields of secondary data packets. The commands can be used to cause a target device to capture a frame, enter or exit self refresh mode, or reduce power use of a connection. In addition, a request to exit main link standby mode can cause the target enter training mode without explicit command to exit main link standby mode. | 03-29-2012 |
20120117285 | PROTOCOL EXTENSIONS IN A DISPLAY PORT COMPATIBLE INTERFACE - A computer can control a target device using a packet format described herein. In one example, an extension packet controls the target device in at least one of power consumption, image rendering, and register updating. | 05-10-2012 |

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 |
