<p>A system for generating an image in an RLCD using current sources instead of voltage sources to reduce noise and power consumption. The current is provided by a plurality of RAM-driven IDACs. Each IDAC drives one of a plurality of RLCD columns in conjunction with one of a plurality of OTAs. A Look-Up-Table in each RAM holds a plurality of 6-bit digital values that correspond to the time-derivative of the values contained in gamma correction curves. The LUT values are automatically corrected at the end of each display cycle by an auto-correction.</p> |
