Overall Block Diagram
The TC-26/32LX60 and 600 series LCD Direct View TVs differ from previous
models in that all signal processing is accomplished on the A board. The
video processing function that had been previously accomplished by the DG
board is now performed on the A Board by IC4002. This IC serves as the
Main micro and Video /Audio Panel controller. IC4004 is a Field
Programmable Gate array that is responsible for the pixel conversion and
addressing of the Active Matrix display within the LCD Panel. This IC also
contains the low voltage differential signaling (LVDS) transmitter used for the
conversion of the 8-bit RGB video into a differential RGB output signal. The
LVDS receiver on the LCD panel converts the differential RGB output signal
from the A board into an 8-bit RGB signal that is output to the LCD Panel.
