LCD monitors for 24/7 use from eyevis

eyevis LCD video wall (PresseBox) ( Reutlingen, )
Today, LCD monitors are more and more used in digital signage applications, small control rooms, Pointsof-Sale, Pointsof-Waiting, Pointof-Information applications for the display of advertisements, information, schedules or control room content such as CCTV cameras or critical surveillance applications. In some of these fields of application, the monitors are not in operation the whole day, but in some of them the systems run 24 hours on 365 days a year. Up to now it was not recommended to use LCDs more than 20 hours per day because of "image retention" damaging the displays, also known as "image persistence" or memory effect, especially when displaying static pictures. Eyevis has now introduced their new display versions EYE-LCD-4200-24NB and EYE-LCD-4700-24-NB. Both displays come with various features enabling their use in 24/7 operation. The displays have a narrow bezel of only 15 mm and a robust aluminium chassis, which makes them a first choice for stable installation in modular video wall arrays. The monitors have native FullHD resolution and a size of 42" for the EYE-LCD-4200-24NB and 47" for the EYE-LCD-4700-24NB. They are equipped with various input possibilities for video and data signals. In total the displays provide 2x Scart, for video 3x Cinch, 1x Mini-DIN, for audio 4x Cinch, for PC 15 pin HD-Sub, serial 9 Pin HD-Sub, Digital PC/video interface 2x HDMI (DVI-D), PC Audio input 2x Cinch, audio output 4x Cinch. The simple video setup is guaranteed by an internal scaler with a matrix function for predefined clusters like 2x2, 3x2, 3x2, 3x3, 3x4, 4x3 and 4x4. The displays can be used in landscape or portrait mode. The displays can be operated in 24/7 operations when observing certain prescriptive limits and when using them within recommended operating conditions. Eyevis has integrated several optimised features in order to increase the lifetime of the system and for protection.

The features are the following:
-Black and White Optimisation:

Optimises the display of very small details. Particularly in dark areas, even the smallest details - not visible on conventional displays - can be displayed generating an extremely brilliant and highcontrast image.

-Intelligent cooling concept:

The intelligent cooling system works in two cycles, an open loop and a closed loop. Depending on the display size and its power consumption, one, two or more air ventilation ducts can be integrated. Furthermore, a special sealing method avoids dust accumulation inside the display. The cooling system is very energy efficient and maintenancefree, reducing the cost of ownership.

-Dynamic control of contrast:

A very complex technique allows incessant correction of both the backlight brightness and contrast of the TFT cells, resulting in a natural, very highcontrast image. Additionally, this results in reduced power consumption.

-Intelligent Dynamic Noise Control:

Intelligent algorithms suppress the "noise" typical for analog signals, while optimising image performance.

-Dynamic Pixel Refresh:

A special system driving the TFT cells avoids image sticking and increases display lifetime considerably.

-Dynamic Pixel Shift:

Continuous shifting of the entire image in different directions prevents image sticking. At normal viewing distance, this is almost not visible. If required by the application, the shifting area can be adjusted manually.

-Smooth Contrast:

An intelligent scaling mechanism smoothes extreme contrast transitions. This process avoids the so called boundary line image sticking, which occurs at "hard" transitions (e.g. black to white). If required, the degree of "softening" can be adjusted manually.

-True Film Function:

True Film Function uses special algorithms allowing film reproduction (DVDs) in amazing quality. This applies not only to commercial standard definition DVD material, but also to DVD films in HD 1080i (e.g. Blu-Ray).

With these new displays eyevis sets new standards in terms of image quality, reliability and durability. These displays are the ideal solution for professional applications, where standard LCDs reach their limits.
