Вака сега, има 3 типа на телевизори.
Currently, LED-backlit LCD TVs use one of two systems.
Edge-lit: LEDs are placed along the edges of the LCD panel
Full array: Rows of LEDs are placed behind the entirety of the LCD panel
Which is Better? Edge-lit or Full Array?
Each system has advantages and disadvantages, and the one that’s right for you depends on your needs and desires. Edge-lit sets are typically much thinner and lighter than those that use a full array because the lighting source takes up less space. Full-array sets are thicker and heavier, but they make up for that with local dimming, which means one section of the LED panel can be dimmed while other sections remain bright. That improves blacks and contrast in the resulting picture.
In short, sets that use full-array backlighting tend to produce the best picture of all LCD TVs. Those that use edge lighting sacrifice picture quality but are the lightest and thinnest TVs on the market.
