At a LED monitor the illumination is taken over by LEDs. These are considered more energy efficient and can have brighter and brighter colors on the monitorShow. But which LED monitor is actually the right one? Because LED does not always mean the same LED.

LED monitor – General

At a LED monitor Different lighting methods must be distinguished, which affect the image quality. The most common and at the same time cheaper form of an LED monitor is the one in which the display and the tubes are illuminated from the edge. Such a LED monitor is also referred to as an edge monitor. The positioning of the LEDs in this case allows a very flat design, in which up to one centimeter case depth is possible.
In addition, there is also the so-called full-LED technology, which is also known under the name LED Pro. The LEDs are located directly behind the pixels in such monitors. For this reason, these can be targeted. However, this does not mean that there is an LED behind each pixel. Rather, the screen consists of several equal areas, each of which is illuminated by an LED. This method of illumination allows better illumination of the entire monitor surface. A better black representation owes such a LED monitor the fact that the diodes can be completely switched off or dimmed. This will prevent a backlit. On the other hand, with such monitors, however, individual darkened areas may also occur because a group of LEDs is always dimmed. Such LED monitors achieve the highest contrast value and the strongest color representation. Unlike the edge monitors, however, they are slightly more expensive and not so flat in design.

LED types

One differentiates the LEDs not only according to their position, but also after their kind. One distinguishes thereby between RGB and white diodes. While the white diodes only shine in white, the RGB diodes allow the representation of primary colors red, green and blue. monitor screens with white diodes need this color filter, The LED monitors with RGB diodes have a better image display, but are also much more expensive.

OLED monitor screens

OLED technology is an advanced technology of LED technology. In this case, the LED diodes also take over the illumination of the monitor. But in this case, it is not a crystalline base, but organic components. The biggest advantage of OLED technology is that the image contrast is higher, the colors shine more clearly, and the response times are shorter. In addition, no backlighting is required for organic light emitting diodes, as these light themselves. As a result, light and color filters are completely superfluous. Such monitors can be built even flatter. In addition, their energy consumption drops even more compared to the normal LEDs.

Other important features of LED monitors

Anyone who thinks about buying an LED monitor will be confronted with more terms. For example, with the term image repetition frequency. This is understood to mean the change in the transistor voltage per second, or the switching on and off of the LEDs. 60 hertz are considered perfectly adequate.
The luminosity represents another important concept. This is measured in Candela. The higher the indication, the better the picture quality. 200 Candela are considered sufficient for a good picture. When contrasting, make sure that it is at least 350 to 1. However, dynamic contrast is understood to mean the distance between the brightest set and the darkest set pixels at different times. This is opposite to the normal contrast value.
Otherwise, a small angle does not necessarily mean something negative. Because if several people are in the room and you do not want the content of the screen to be recognized by the next table, you prefer to choose a smaller viewing angle. If that does not really matter, you should make sure that the angle of view is as close as possible to that of 180 degrees. Because this represents the maximum indication both in the horizontal and in the vertical.
