Utilizing Gray Code to Reduce Power Consumption in Display System

摘要

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.

1. A method for utilizing Gray code to reduce power consumption in a display system, the method comprising:
receiving binary timing controller (TCON) data from a TCON; converting the binary TCON data to a Gray code data and a binary portion of data; performing column driver operations on the Gray code data and the binary portion of data; decoding the Gray code data and the binary portion of data; and determining a gamma level for column driver output.
