the driver circuit for the light valves.
Timing signals output from the display controller are converted into signals for the light
valves (LCDs) by the D/A converter and LCCOM circuit before they are output.
The filter/gate circuit is designed to reduce noise influence on the display driver circuit.
To reduce impulse noise, input signals are sent through the three-level filter circuit. To
reduce the effects of timing delays on the logic, gate circuits work as trigger circuits for
each signal line (R/G/B) and unify the output timing.
The flash ROM contains electrical correction data for the image display. The display
controller reads the correction data. The controller uses the correction data for display
timing generation, brightness / contrast / chroma and density control.
Light valve driver circuits convert the input analog signals to the LCD (Liquid Crystal
Display) driver signals.
