M52338FP
INTERFACE IC FOR ACTIVE MATRIX LIQUID CRYSTAL PANEL
DESCRIPTION
The M52338FP is a semiconductor integrated circuit containing an
interface circuit which is necessary to drive an active matrix liquid
crystal panel.
FEATURES
•γcorrection circuit is built in to correct non-linearity of luminance
characteristics caused by applied voltage which is peculiar to a
liquid crystal panel.
• By combining with Mitsubishi video/chroma signal processing
ICs, M52042FP (NTSC) and M52045FP (PAL), low cost and
optimal system configuration is possible.
APPLICATION
Active matrix liquid crystal color television
