LED backlight technology

LEDs are used to provide illumination for the display screens of most BRAVIA® TVs. There are three types of LED backlighting system: Edge LED, Dynamic Edge LED and Intelligent Dynamic LED.

How LED backlighting works

The LED backlighting system inside BRAVIA TVs uses individual White LEDs (Light Emitting Diodes) arranged behind or at the top and bottom of the television’s LCD (Liquid Crystal Display) screen to provide light for the picture.

LED backlighting uses less energy than conventional CCFL (Cold Cathode Fluorescent Lighting) backlighting, and allows thinner television sets to be built. LED backlighting can also deliver very high contrast, by directing light only to the areas of a picture which need to be bright – and leaving the dark areas un-illuminated.

Our TVs use three types of LED backlighting: Edge LED, Dynamic Edge LED and Intelligent Dynamic LED.

Edge LED for the ultimate, slim design statement

Edge LED

In televisions with Edge LED backlighting, the TV picture is illuminated by white LEDs which are arranged along the top and bottom edge of the liquid crystal display panel. A special guide plate then directs the light so that it shines out through the screen. Because there are no LEDs directly behind the screen, Edge LED televisions are incredibly thin and lightweight.

Dynamic Edge LED - rich cinematic picture in a slim design

Dynamic Edge LED

Like the Edge LED system, Dynamic Edge LED backlighting uses white LEDs arranged along the top and bottom edge of the TV’s LCD screen. Local-dimming technology then controls the light output of individual groups of LEDs depending on the image showing. This gives remarkable contrast of bright and dark areas in the same scene.

Intelligent Dynamic LED - get a real cinematic feel

Intelligent Dynamic LED

Unlike Edge LED, the Intelligent Dynamic LED backlighting system uses many more white LEDs arranged directly behind the television’s screen to illuminate the picture – this is commonly known as Full or Direct LED. Controlling the light output of individual blocks of these LEDs means the system can light very specific parts of the picture, while leaving others dark. This gives your television picture exceptionally high contrast; displaying the deepest blacks yet still showing the detail in those dark scenes. All in all, you see award winning picture performance.
