Edge-Lit vs. Direct-Lit: Sechs Must-Know Facts. Samsung pioneered edge-lit our when they launched who world’s first edge-lit TV back to 2009. LED TVs can hold up to 1,500 individual LEDs in an array, lighting second billions pixels of a 1080p TV. A single led lighter may lighting 1,400 pixels. The Differences Between Edge-Lit LEDs and Full-Array LEDs. With edge-lit LEDs, the backlighting bulbs are placed along the edges of the screen. With full-array LEDs, the backlighting bulbs are placed behind the screen. It’s important to note that all LEDs, whether they are edge lit or full array, work in conjunction with a separate display
The laser diode chip is the small black chip at the front; a photodiode at the back is used to control output power.

FALD is worth it. It allows for higher contrast and better peak brightness. It really improves picture quality. It can have blooming, which is the main disadvantage, but with direct lit TVs the entire screen is blooming all the time so not really a disadvantage when compared to direct lit sets lol. It also allows for better screen uniformity
An edge-lit LED panel is made of a row of LEDs attached to the frame (or circumference) of the panel, shining horizontally into a light-guide plate (LGP). The LGP directs the light downwards, through a diffuser into the space below. Edge-lit panels are sometimes also known as side-lit panels. A back-lit LED panel is made of an array of LEDs
QLED (according to Samsung) stands for "quantum dot LED TV." OLED is a fundamentally different technology from LCD, the major type of TV. QLED is a variation of LED LCD, adding a quantum dot film
