Timing Generator for LCD Panels
CXD2443Q
Description
The CXD2443Q is a timing generator for the LCD
panel LCX011 and LCX019 driver. This chip has a
built-in serial interface circuit which allows various
settings to be performed through external control
from a microcomputer, etc.
100 pin QFP (Plastic)
Features
• Generates the LCD panel LCX011/LCX019 drive
pulse
• Supports NTSC/PAL
(PAL supported by scanning line conversion of
video signal to 525H or pulse eliminate.)
• Supports WIDE mode (when driving the LCX011)
• Supports HD mode (when driving the LCX011)
• Supports up/down and/or right/left inversion
• Supports 3-panel projectors
• Generates timing signal of external sample-and-
hold circuit
• Generates line inversion and field inversion signals
• AC drive of LCD panels during no signal
• Line double-speed display realized with a built-in
double-speed controller (NTSC/PAL) (4:3 mode only)
(Line memory µPD485505: NEC)
