Having obtained popularity among the HDTV-buying public in recent times, LED TELEVISION is in itself a misnomer.
These LED televisions are actually not real LED screens; rather, as an outcome of some imaginative (and possibly deceiving) advertising and marketing by makers and merchants, an "LED TV" in today's market usually describes an LCD TV that utilizes LED backlight as opposed to typical cold-cathode fluorescent lamps (CCFL) to brighten its screen. For the purpose of preserving technical precision, we attempt to utilize the terms "LED-backlit LCD TV", "LED-based LCD TV", "LED LCD screen" or "LED LCD TV" whenever possible in our evaluations when referring to LCD televisions with LED backlighting.
Local Dimming LED TV
When LED backlighting was first introduced on LCD panels, its target is to create much deeper blacks than what could possibly be attained with CCFLs. The method traditional LCD TVs creates black is by "shutting out" the always-on fluorescent backlight. As you could visualize, this somewhat ineffective approach generally outcomes in a lighter shade of black because of light leakage.
So some wise TV engineers started believing, suppose we could turn off the backlight on the LCD screen as essential for black-level reproduction? Cue the birth of LED-backlit LCD tvs-- LEDs which can be turned on and off are mounted behind the LCD matrix in area of the more space-and-energy-consuming fluorescent bulbs. Just what this implies is that a specific location on screen could be darkened (by turning off the LEDs) separately from various other brighter areas (where the LEDs are turned on), contributing to lessened light leakage and substantially further blacks.
Exactly how local-dimming LED works-- backlight zones can be dimmed or lightened up individually
But due to the fact that it is too complex and costly to designate an individually changeable LED to every pixel (for instance a comprehensive HD 1920 x 1080 LCD panel would certainly call for in surplus of 2 million LEDs), to keep prices down the LEDs are deployed in separately controllable blocks / selections of "dimming zones".
An ultra slim edge-lit Samsung LED TV measuring 3cm detailed.
Nonetheless, their sheer slenderness means that edge-lit LED-based LCD TVs usually manifest worse screen uniformity and weaker audio performance. And as a result of the worldwide nature of any type of backlight modification (i.e. the whole backlight needs to be dimmed down or cheered up with each other), edge LED panels struggle with poorer black degrees (compared with local-dimming variations) when showing series with mixed brightness, and lesser regarded comparison when displaying mainly dark material...
