Direct-lit LED monitors to belong to the lower end of LEDs because of their construction. They are most similar to full-array LED by design. But, considering the number of led diodes (there are just a few of them) they can not be controlled separately. Direct LED monitors are a bit thicker than Edge-Lit LEDs.
By design, they resemble LCD monitors. Primarily we have them because of their price. This type of monitor is often cheaper than edge-lit models. In most cases, they are least expensive models on the market with leed diodes. The main advantage over classic LCD models is their energy efficiency.
