LCD PANEL ASSEMBLY
The LCD Panel Assembly includes the LCD Panel, TCON Board and
Backlight system.
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 backlight - 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 will include the following items:
●
LCD Panel
●
TCON Board (Internal - not available as a replacement part)
●
Inverter MT Board
TCON BOARD
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.
INVERTER MT BOARD
The inverter receives the unregulated 24V from the Power Supply Board
and generates the required high voltage AC to power the backlight lamps. A
control line to turn on the inverter (backlights on) is used in conjunction with
a dimmer control to vary the light level of the CCFL lamps.
