The serialized data (LVDS) from
the A-board is converted to
parallel by the ZWEI2 IC. The
data is then processed by the
timing control IC (TCON) to
convert the RGB data into serial
streams for processing by the
drivers of the LCD panel. The
drivers are mounted on circuit
boards to the top and side of the
panel. Shift registers and drivers
provide the drive signals to the
rows and columns of pixels on
the panel.
The TCON IC produces the data
that drives the LCD panel.
