  • Publication number: 20180190220
    Abstract: A method including receiving a first row of display data for a first time period, and determining a value of a specified bit position for first portions of a first plurality of multi-bit portions in the first row. The method further includes receiving a second row of display data for a second time period, and determining a value of the specified bit position for second portions of a second plurality of multi-bit portions in the second row. Based on the determining, identifying second portions that indicate a change in the value of the specified bit position from the first time period to the second time period, and identifying an output channel associated with each identified portion. The method further includes grouping each identified output channel into a first or second group based on a polarity type, and connecting the identified output channels together within each group.

  • Publication number: 20180182329
    Abstract: A method including receiving information and a row of display data for display on a row of a display panel, sending the data to channels in accordance with the information, each channel supplying a portion of the row of display data to a column of pixels in the display panel using one a source driver, outputting, by a plurality of source drivers, the row of display data to the row of the display panel, and receiving a row completion indicator subsequent to the outputting. The method further includes determining, during a polarity period, a polarity state of a portion of the row of display data, identifying a group of source drivers, generating charge sharing enable signal(s) using the row completion indicator, and connecting outputs of source drivers in the identified group of source drivers together during the polarity period using the charge sharing enable signal(s).

  • Patent number: 9418607
    Abstract: 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.
