Overview
The LC74772V is a CMOS LSI that implements on-screen
display for camcorders. It displays characters and patterns
in a camcorder viewfinder under microprocessor control.
The LC74772V displays a 12
× 18 dot font with 256
characters.

× 24 characters (up to 288
characters)
Number of characters displayed: Up to 288 characters
Character format: 12 (horizontal)
× 18 (vertical) dots
Number of characters in font: 256 characters
Character sizes: Normal and double, specified in line
units
