9.7.2 Full-HD sets @ 50 / 100 Hz
In full-HD sets @ 50 / 100 Hz, the output signal coming from the
PNX8535 is fed to the PNX5050 and then to the PACIFIC 3.
The PACIFIC 3 also generates the pulse-width modulated
signal needed for the “Dimming Backlight” feature, which
ensures additional motion sharpness. As some displays
require an analogue signal to switch the LCD, a multiplexer is
added to transform the puls-width modulated signal. An
additional signal, coming from the PNX8535, makes the
selection between analogue and pulse-width modulation,
depending on which display is used. Scanning Backlight
displays require an analogue signal, and all other displays a
pulse-width modulated. The signal for “Scanning Backlight” is
an I
2
C signal coming from the PNX8535.
