LC749880T
No.A1186-3/17
2. Adjusting the panel picture quality
2-1. White balance
White balance adjustment appropriate to LCD-TV is possible.
2-2. Black balance
Black balance adjustment appropriate to LCD-TV is possible.
2-3.
γ correction
γ correction appropriate to LCD-TV is possible. The γ correction curve may be made programmable by means
of LUT
γ correction can be made independently by RGB.
3. Color exciter
A total of 12 colors including red, green, blue, magenta, yellow, cyan, and colors between these colors can be
adjusted independently in terms of saturation.
4. Shadow adjuster
The three-dimensionality can be emphasized by adding the shading through addition of the adequate peaks before
and after the detected input signal contour.
5. Dither
In the case of 6-bit output, pseudo-mulltiple tone processing enables the output equivalent to the 8-bit output.
Panel Interface
1. Video output
Digital RGB 24-bit/18-bit output possible
2. Synchronizing signal (timing controller) output
Timing controller output and synchronizing signal output (horizontal/vertical synchronizing signal, data enable)
possible.
The output can be selected according to specifications of LCD module.
Others
1. OSD interface
This LSI has no OSD.
OSD can be interfaced with the external OSD microcomputer by means of the input pin (Pin Nos.: 105 to 108) and
output pin (Pin Nos.: 96,103,104).
Interlace synchronization/progressive synchronization can be changed over according to register setting.
The closed caption can be displayed.
2. I
2C bus interface
The internal register is controlled by means of I
2C. The slave address can be changed over by controlling the
“I
2CSEL” pin (Pin No: 33) according to the system.
I

“L”
Slave address “88H”
