Description |
|
TW8810 is a high performance integrated LCD display
processor designed to support SHARP Dual View LCD
panels for in-car display applications including navigation
systems, in dash DVD players, rear- seat/head-mount
displays, and automotive TVs. The chip uses a single
27Mhz crystal, comes in a 208-pin PQFP package and
is qualified for automotive applications including
-40C to +85C temperatures and 1,000 hours of reliability
testing. TW8810 requires an external 64mbit SDRAM
to suppor t dual view and other advanced functions.
Inputs include composite video, s-video,YPbPr, analog
RGB, 24 bit digital RGB and 8/16/24 bit YCbCr. For
composite video streams, a high quality 3D comb filter
for NTSC and PAL with concurrent 3D noise reduction
is integrated to reduce artifacts typically found
in analog video signals.
In addition to a 3D comb filter, a number of proprietary
image processing algorithms are implemented in TW8810
to improve picture quality including a built in 2D-deinterlacing
engine with low angle compensation, black/white stretch
and color enhancement.TW8810 has a sophisticated PIP
function that includes Picture in Picture (PIP) with
variable sub-window size, picture over picture (POP),
and multiple PIP.
The TW8810 on-screen display can select 256 colors
from 24-bit colors (16.7 million colors) and is a
graphic style OSD with a variety of functions including
blinking, transparency, blending, and multi-window
support. The TW8810 also supports external 18-bit
OSDs with external
