Functional
Description
The AL300B evaluation board is used to demonstrate
the versatile capabilities of the AL300B LCD Controller.
The AL300B is designed to enable simple connection
from PC’s or video devices to flat panel
displays. It provides LCD/PDP monitor and projector
manufacturers with a low-cost, easy solution to
bring TV or PC video to LCD panels.
The AL300 is equipped with a high quality zoom
engine that automatically maintains full screen
output display, regardless of the resolution
of the incoming signal. The input video can
be linearly and independently zoomed in the
x and y directions. The AL300 also provides
de-interlacing, filtering, and scaling support
for interlaced video to be displayed on a LCD
panel.
Two integrated On Screen Display (OSD) windows
provide overlay of a control menu, text, or
caption on the output display. With the internal
OSD RAM, OSD bitmaps of up to 8K pixels are
supported. With optional external user-defined
font table ROM, the AL300 OSD
functionality is very flexible with font size
and display location; virtually all languages
and fonts are supported. Special OSD effects
such as translucency and blinking offer the
manufacturer a unique and vivid way of presenting
monitor status, control menu, or other display
information.
Used with an AL875 (high speed 3-channel ADC
with PLL, 100-pin QFP), the AL300 (in 160-pin
QFP) offers the best cost-performance and total
solution for LCD monitors or projectors, or
other flat panel devices. |
