Glossy display

As a glare-type display (from the English for screen type with shiny or dazzling surface ) flat screens are called, which have a highly reflective surface.

Special

TFT panels of flat screens consist mainly of glass and thus have an inherently smooth, reflective surface. The matting traditional flat panel displays is achieved by a special diffuse coating, which scatters the ambient light. In glare-type display, this coating is missing. Specialized in display repair companies now offer a subsequent laminating these special films, making it easy to glossy screens also subsequently antireflection coating. Manufacturer of glare-type display advertise with higher contrast values, because the matte surface of traditional flat panel reduces the contrast ratio. Especially with sharp transitions between extreme difference in luminance ( eg: black → white) is the lack of scattering visible. However, since most is liquid crystal display with simple TN panels with glare-type display, the contrast range of this kind panels can not be compared with higher-quality IPS and VA panels.

Because of the often strong reflections glare-type display are ergonomically questionable and is not suitable for working in environments with strong light sources. Especially in the professional environment reflective displays because of the requirements in the Annex to Bildschirmarbeitsverordnung ( Display Screen ) to consider special. However, in some display tinted glare-type films are used, the coating results in a less clearly perceptible direct glare of the user.

Standardize

The Bildschirmarbeitsverordnung (based on European Directive 90/270/EEC screen ) requires that largely screens must be free of glare and reflections. However, this applies only for so-called workstations.

The standard ISO 9241-7 ( Ergonomic requirements for office work with visual display terminals - Part 7: Requirements for visual displays with reflections ) is formulating appropriate measurement techniques and requirements. Monitors are then divided into three different reflection classes.

Class I with the lowest reflection is suitable for general office use. Class II with less favorable reflection behavior is not suitable for all office environments. Class III, which belong to the glare-type display, requires a special, controlled ambient lighting for use.

Criticism

The trimmed gloss screen types have indeed a " subjective" higher contrast impression as an anti- glare-type display, since the maximum brightness increases slightly and the display is refined with a high gloss coating. The black level, however, remains at the same height, and therefore the actual contrast hardly increases. However, the reflective screen surface complicate both changing as well as lateral and oblique beaming from above light sources, a fatigue- free reading of the monitor image (about outdoors, in bright office rooms or in trains ).

What the ambitious computer gamers or video consumers is likely to interfere with dimmed ambient light probably little, but is problematic in a workplace. It would be difficult in normal office environments and in observance of the screen requirements to find a setting for the screen, in which bright areas are not on the surface reflect ( such as lamps, windows or bright walls behind the user, light-colored clothing, face, etc. ). Glare - type displays are for the professional and semi- professional photo editing usually unsuitable, because it usually is the TN panel, which so far can not provide the required and practically relevant color fastness usually. In particular, the representation of pastel tones and light gray gradients is often worse than usual. An adjustment of the tone curve in the settings of the graphics card can partially compensate for this, however.

To have been sold significantly more expensive than their matte screen counterparts despite supposedly slightly smaller production costs glare-type display on the launch. But the fact is that the lack of AR coating for the manufacturer of TN screens is a cost effective way to play compared to newer and more expensive IPS and VA techniques Inherent disadvantages of TN technology, such as low contrast and strong viewing-angle dependence.

Brand names
