Part number: KCD-A300-QB
(August. 09, 2006)
General Description
The A300 is a driver for Kopin’s CyberDisplay®
300M LV monochrome display. It is designed to
accept a standard monochrome video signal (525
or 625 lines), and convert it for the display.
The A300 provides all necessary power supply
voltages to the display panel by means of charge
pump circuits. The input video signal is
converted to appropriate differential video
signals required by the LCD Display Panel.
A separate on screen display (OSD) input is
provided. An on-chip sync separator, Digital
PLL, and logic control section generate the
appropriate horizontal and vertical timing signals
for the LCD panel.
