|20150042551||Utilizing Gray Code to Reduce Power Consumption in Display System - A system and method are disclosed to utilize Gray code in order to reduce the power consumption of column drivers in a display system. Binary source data is received from a timing controller. A Gray code digitizer converts and encodes the binary source data into a binary portion of data and a Gray code data. The binary portion data and the Gray code data are transmitted through a shift register to a digital-to-analog converter. The shift register consumes less power processing the converted binary portion of data and Gray code data than the corresponding binary source data. The digital-to-analog converter decodes the Gray code and generates corresponding gamma voltage levels for display use.||02-12-2015|
|20140168187||Power Reduction Technique for Digital Display Panel with Point to Point Intra Panel Interface - A system and method are disclosed to control the power consumption of column drivers in a display system. A video input signal is received which has an active video period and a vertical blanking period between frames. A timing controller transmits a first video frame to a column driver. The timing controller transmits a column driver disable command during a vertical blanking period. Prior to the subsequent active video period, the timing controller transmits a column driver enable command. The timing controller proceeds to transmit a second video frame to the column driver. In one embodiment, the timing controller determines whether to disable and enable the column driver based on a refresh rate, the refresh rate calculated by the timing controller from the video input signal.||06-19-2014|
|20120307154||HYBRID MODE REPEATER/RE-DRIVER FOR HIGH SPEED DIGITAL VIDEO SIGNALING - A system and a method are disclosed for a hybrid mode re-driver which, among other advantages, reduces power consumption while maintaining signal integrity. Equalization is performed on a signal to remove distortions such as inter-symbol interference. The signal is then analyzed and the quality of the signal is assessed. In some cases, retiming is then performed on the signal to remove additional signal distortions. In other cases, retiming is not performed and is transmitted to a driver while bypassing retiming components. When retiming components are bypassed, the retiming components are placed in a state of reduced power consumption to reduce system power consumption.||12-06-2012|
|20110150055||Active Auxiliary Channel Buffering - A system and a method for communicating configuration data between a source device and a sink are described. An active buffer receives data from an auxiliary communication channel which communicates data between the source device and the sink device. The active buffer modifies data received from the auxiliary communication channel. For example, the active buffer amplifies the received data or electrically reshapes the received data. The modified data is then transmitted from the active buffer to a destination device. In one embodiment, the auxiliary communication channel is bi-directional and upon receiving data from a first device, the active buffer is modified to permit uni-directional transmission of data from the first device to a second device.||06-23-2011|
|20110149796||DisplayPort Auxiliary Channel Active Buffer with Auxiliary Channel/Display Data Channel Combiner for Fast Auxiliary Channel - A system and a method for exchanging communication data between devices using a bi-directional communication channel are disclosed. A combiner is coupled to a source device via first bi-directional configuration channel and to a sink device via a second bi-directional configuration channel. Upon receiving data from the first bi-directional configuration channel and not receiving data from the second bi-directional configuration channel, the combiner transmits the received data to the sink device using the second bi-directional configuration channel and prevents data transmission from the sink device to the source device using the second bi-directional configuration channel. Similarly, upon receiving data from the second bi-directional configuration channel and not receiving from the first bi-directional configuration channel, the combiner prevents data transmission from the source device to the sink device and transmits the received data to the source device using the first bi-directional configuration channel.||06-23-2011|
