Look-Up Table Access Mode bits [1:0]
These bits specify the mode used to access the Look-Up Table (LUT).
Gamma Correction Enable
This bit controls gamma correction.
When this bit = 0, gamma correction is disabled and the input data will bypass the gamma
correction look-up table.
When this bit = 1, gamma correction is enabled and the input data will go through the
gamma correction look-up table.
REG[50h] bits 2-1
Gamma correction is implemented as a look-up table. RGB input data (YUV input data
is converted to RGB) is used to look-up the values from the programmed tables. The
Gamma LUT’s are placed on the display read path and the 24-bit output goes to the
LCD interface.
The Gamma Correction Tables should not be accessed during display period as this will
result in visual anomalies. All updates to the LUTs should be performed during non-dis-
play period or when the LUTs are disabled and not in use.
