LC74736PT规格书详情
Overview
The LC74736PT is an on-screen display CMOS IC that displays characters and patterns on a TV screen under the control of a microcontroller.
For QVGA display, the LC74736PT supports the use of both a 16 × 16 dot character font and a 16 × 16 dot graphic font with 16 colors.
For WVGA display, the LC74736PT supports the use of both a 24 × 32 dot character font and a 24 × 32 dot graphic font with 16 colors.
The LC74736PT can also implement extremely varied displays by the use of an external ROM.
The LC74736PT supports both QVGA (480×234) and WVGA (800×480).

(4) Character sizes: Four horizontal sizes (1×, 2×, 3×, and 4×)
Four vertical sizes (1×, 2×, 3×, and 4×)
(The character size is specified in line units.)
(5) Display start positions: 1024 positions in the horizontal direction and 512 positions in the vertical direction.
Setting units: Horizontal: 1 dot (in screen units)
Vertical: 1 dot (in screen units)
(6) Display functions
• Blinking specification (in character units)
Period: 1/64, 1/32, and 1/16 of the vertical sync signal (in screen units)
Duty: Fixed at 50
• Box (raised or recessed) display
Raised/recessed specification (in character units)
Left: Off/on specification (in character units)
Right: Off/on specification (in character units)
Top: Off/on specification (in character units)
Bottom: Off/on specification (in character units)
• Border specification (in line units): Only valid with glyphs from the character font.
(7) Color specification
Character
• Character color (in character units): 1 of 16 colors can be specified.
• Character background color (in character units): 1 of 16 colors can be specified.
