Local Dimming

Local dimming on an LED TV improves black levels and contrast ratios to deliver a better picture, it’s a key technology in the TL515 LED HDTVs. But while conventional local dimming modulates the backlighting in certain areas of the display showing darker elements of the scene, Toshiba takes the concept a step further by providing many more dimming zones than average, providing a significantly better picture.

Better contrast. Picture quality beyond compare

Backlighting is divided up into different zones consisting of multiple LEDs. Each cluster can be controlled individually and adopt its own brightness value. Toshiba has also developed a special diffusion filter, which can be used to distribute the light within a group of LEDs even more accurately. This advance technology enables the screen to be illuminated much more precisely than was previously possible.
