... 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 I 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., ...

... After adjusting the gamma, the signal gain and DC voltage can also be adjusted. 3. SIDOUT SIDOUT generates the precharge signal. After the CXA2111R determines the DC level (Pins 9 and 11) and the pulse width (Pin 10), the signal is inverted by the CXA2112R and applied to the LCD panel. See the Example of Representative Characteristics for the DC level. ...
