This system is not used much, since the image quality it provides is inferior to the previous cases. On the other hand, displays that use RGB LEDs (that is, with red, green and blue primary colours) provide an even greater colour palette. Of course: as a disadvantage compared to this latest technology, it should be noted that the thickness of the screen will be somewhat greater. Hence, the feedback it offers is more homogeneous than that of the Edge LED. In this case, the LEDs intended for backlighting are hidden behind the LCD screen, encompassing it in its entirety. The distribution of diodes in Full LED screens is already used by many televisions. Of course: Edge LED screens are thinner than the latter. However, the presence of light reflectors ensures homogeneous illumination over the entire surface of the screen, although not with as much precision as in Full LED monitors. With this type of screen, the light-emitting diodes are distributed along the entire edge of the screen, either completely surrounding it or occupying only one of the four ends. Having made this clarification, let us see in greater detail what characteristics these two LED technologies present, and we will also talk about others that are currently for sale. Likewise, we should also refer to Full LED or Full Array LED technology, in which the diodes are distributed over the entire surface of the screen. In this way, the screens are much thinner, with thicknesses that sometimes do not exceed 3 cm. One of the most common is Edge LED technology, in which diodes are located at the ends of an LCD monitor. Today, there are several types of LED technologies on the market, which are marketed in combination with LCD displays.

What’s more, the images offer even higher contrast, as well as an even higher black gamut. They work in a similar way to conventional LCD monitors, but with 40% lower power consumption, and without affecting the resolution or brightness of the image. LED screens are very similar to LCD screens (liquid crystal display, or liquid crystal display), although they use a more homogeneous backlight technology.
