LCD Panel Assembly

The LCD Panel Assembly includes the LCD Panel, TCON/HFR Board ,
and CCFL 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. The HFR (High Frame Rate)
section performs the 60Hz to 120Hz frame refresh rate conversion.
