CXA2111R
LCD Signal Processor (Gamma Correction)
Description
The CXA2111R is a signal processor IC developed
for LCD panels. Gamma correction, gain and bias,
etc., can be adjusted using the I2C bus and external
adjustment pins. The output of this IC is ideal as the
input of the CXA2112R (LCD sample-and-hold
driver IC), and the sample-and-hold position, etc.,
can also be adjusted using the I2C bus.
52 pin LQFP (Plastic)
Features
Independent R, G and B gamma adjustment
Three-point gamma gain and position adjustment
(one white side point, two black side points)
Independent R, G and B output amplifier gain and
bias adjustment
Various I2C bus-based controls and adjustment of
various characteristics by external DC input
Input signal clamp function (variable clamp voltage)
Black side limiter adjustment
