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.

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

• CXA2112R adjustment output

• Precharge output (for CXA2112R)

• High frequency response

• High slew rate output

Applications

• Liquid crystal projectors

• Compact liquid crystal monitors
