2. LOCAL DIMMING FUNCTION
This model employs the local dimming system which controls the brightness individually by dividing the LED’s into 16 x 12 lighting areas for saving
energy and improving the contrast. The difference from the conventional models is as explained below.
In the conventional systems as shown in Fig. 2-2a, video signals are transmitted in the path of the main PWB 
3 LCD-TCON PWB 3 LED. The back-
light is turned ON/OFF by the main PWB.
In the local dimming system as shown in Fig. 2-2b, video signals are transmitted to the LED-TCON PWB, then divided into the two paths; one for con-
trol of LED lighting according images, and the other for displaying images. The LED-TCON controls the LED driver, and controls the brightness of
each area deliberately, lighting LED's at the proper brightness. At the same time, the corrected images according to the LED lighting are transmitted
to the LCD-TCON. The both operations work together to display proper images. The LED-TCON PWB and the LED driver PWB are the great factors
of the improvement in this model.
