What is dled vs led

Learn more. I think the last three letters are known to everyone, they are light-emitting diode. But what is D we still need to explain. It is clear that it is a matrix screen with LED backlighting. In fact, almost no other matrixes are produced nowadays. Manufacturers have upgraded production and moved the backlighting to LEDs instead of lamps. This is more economical, and also allows you to make a dimming turning off of a particular area of the screen, if necessary, which improves picture quality.

When the diodes are mounted on the full array of the display. Direct-lit LED does not use Local Dimming which enhances the contrast ratio eventually increasing the picture quality. Local dimming — The entire screen is divided into several zones of light. These zones can go dim or bright separately making a portion of the screen darker.

This enhances the contrast ratio and thus increasing picture quality. Better Black Uniformity — As the LEDs are spread across the entire display, the brightness levels produced are uniform and so is the blackness. Therefore, it is very easy to get confused and not understand which screen type will be the best choice for you.

Other types of screens are practically not produced. LED technology has too many advantages, so it has actually become the only technology used in modern TVs, monitors, and smartphones. LED screens provide high picture quality, combined with a fairly simple manufacturing method and low cost. That is why it is now used in most TVs. However, there are some differences between the different types of LED screens.

For example, in the LED screen backlighting can be installed directly or on the side. The only difference is the way the backlight is installed. And you have to understand that.
