As a substitute of lights alongside the rim of the TV, these TVs function a whole LED panel behind the display. Extra lights provide extra choices in terms of rising or reducing brightness, which implies these TVs present extra precision and higher element.

These good TVs usually promote quite a lot of ‘dimming zones,’ teams of lights which can be managed in unison. The extra zones a TV has, the extra exact it will get.

Because of this, OLED TVs can obtain an infinite distinction ratio, a measurement of how the brightness a part of the display compares to the darkest.
