Displays

There are suitable display solutions for almost every area of application. We have displays for every area of application and in every price range.

The image resolution of a display is one of the most important properties. This is because, in addition to contrast, brightness and viewing angle stability, it ultimately determines the image quality of a display.

The most popular image resolutions for displays are Full HD (1,920 x 1,080) and 4K UHD. In principle, we recommend 4K UHD over Full HD image resolution, especially for displays with a larger screen diagonal. The reason for this is the usually short viewing distance: the image of a 4K display simply looks more high-resolution and thus also significantly better than the image of a Full HD display for a viewer who is at a short distance from the display.

The brightness of a display is at least as important as its image resolution. As with monitors, this is expressed in candela (cd/m²), or more rarely, in nit (nit). The value of the two units of measurement is the same. This means that 500 cd/m² correspond to 500 Nit and vice versa.

How bright a display needs to be depends on where you want to use it and how strong the ambient light is.

When we talk about contrast, we usually mean brightness contrast, or more precisely: the ratio between the darkest and the brightest point of an image. The greater this ratio, the more attractive and sharper the image appears to us. On most displays, the contrast is in the four-digit range. Common values are, for example, 3,000:1 and 5,000:1. Generally, many displays are comparable in terms of contrast. Both displays with a contrast of 3,000:1 and displays with the 5,000:1 contrast show a very similar, solid image.

Viewing angle stability is the property of display panels that refers to the maximum possible viewing angle at which the displayed image can be shown to the viewer with little or no loss of image quality. The greater this angle, the weaker the loss of quality in terms of colour representation and brightness. 

Displays with stable viewing angles usually have a maximum viewing angle in the horizontal plane of between 160 and just under 180 degrees.

The runtime release is the suitability of a display for continuous operation. The specification for this is made up of the maximum number of hours per day in relation to the duration of a week. As a rule, displays for professional use are designed for 24/7, 16/7 or 12/7 continuous operation. Of course, other specifications such as 10/7 can also be found. In our table, you will find the typical operating times for the respective operating duration.

The most frequently used display connections include HDMI, DVI, DisplayPort and VGA. The HDMI connection is by far the most frequently used in practice. This is because the transmission standard of the HDMI connection is designed for the simultaneous transmission of the audio and video signal. In addition, the HDMI standard also supports the transmission of 4K content. Alternatively, you can also use the modern DisplayPort connection, if available.

DVI and VGA are pure video connections. In addition, the feed via VGA is only analogue, which is why you should rather use an HDMI connection.

Additional connections are interfaces for external control systems such as RJ-45 (LAN) and RS-232 interfaces. Often the displays also have a 3.5 mm jack output and one or more USB ports.

There are usually different options for mounting a display: You can install a display either on a wall mount, ceiling mount or on a display stand. Depending on the area of application and room situation, you can choose the respective solution.

Furthermore, touch displays are often additionally equipped with advanced touch user interfaces, so that their operation by several users at the same time becomes child's play. There are several touch technologies that can be used in touch displays. In the professional large format display sector, these are mainly IR technology and capacitive touch technology. 

Capacitive touch displays are generally better and more precise to control than IR displays. However, they are also more expensive and not yet as widespread. Touch displays are interesting and practical for both education and business. In both, they open up the space for better collaboration and thus for faster knowledge transfer. The best example of this is the Samsung Flip.

Videowall displays are the best eye-catcher. That is why they are preferred for digital signage. Here, several displays are combined to form a larger display area that can be filled with any content: Graphics, videos or animations. It is not uncommon for the videowall displays to have integrated signage players, features for convenient content management and various other functions for individual adaptation on site.  

Displays with OLED technology also conjure up a very high-contrast image. Here, the image is generated with the help of organic light-emitting diodes. The picture quality of these displays is outstanding! In addition, the depth of the housing is very small thanks to OLED technology. Therefore, they can be integrated very stylishly in almost any room. However, they are currently only available as signage and presentation displays, but not as touch displays.
