Overview
The LC74981W is an LCD display scan converter IC that
converts NTSC and PAL TV signals to XGA resolution.
The video signal-processing circuits required to
implement an LCD TV set can be easily formed by
combining this IC with a digital decoder, a
microcontroller, and an LCD panel. Since this IC does not
require an external frame memory for resolution
conversion, it can contribute to minimizing total costs. As
additional functionality, it also provides inputs for
personal computer video (up to XGA) and digital TV
(480p/480i). Since LC74981W operation is based on
expansion (resolution increasing) processing, depending
on the input resolution, it can also support use of, for
example, 800
× 600 and 800 × 480 dot resolution LCD
panels. Thus the LC74981W can be used in a wide range
of applications.
Features
NTSC and PAL input support: 24-bit or 16-bit digital
YCbCr signal input
PC input support: Personal computer 24-bit digital RGB
signal input at resolutions up to XGA
DTV (480i / 480p) input: 24-bit digital YCbCr input
Progressive-scan 18-bit RGB (36 bits two-phase
supported) signal output
YCbCr to RGB conversion
Interlaced to progressive scan conversion
Resolution conversion (enlargement)
Variable display size and display position
(independently settable in the horizontal and vertical
directions)
Image quality adjustments: brightness, contrast, color,
sharpness, color phase, black balance, and white balance
Built-in
γ correction (LUT technique. Each 8-bit R, G,
and B signal is independently programmable.)
Dithering (8-bit to 6-bit conversion)
Built-in OSD function (8 colors, 256 charactors)
I2C bus interface
Constant frame-rate processing (identical frame periods
in the input and output signals) adopted so that no
external memory is required.
