The LCD Panel contains the actual liquid crystals, color filters, and
polarizers. The liquid crystals are manipulated by the applied voltage to
pass a specific amount of light - from the backlite - depending on the level
of voltage applied.
The TCON performs all the control, timing, charge, and discharge functions
driving the operation of the LCD Panel.
A new LCD Panel assembly from parts will include the following items.

The TCON Board communicates between the LCD Panel and the
microprocessor on the Main Board.
NOTE: The TCON Board is not available as a replacement part for all
models. To determine if the TCON Board is available as a replacement
part, refer to the LCD Panels Manual.
