Haze level and the importance of display reflections

Reflections on displays can be very annoying. The more anti-reflective the surface of a display is, the less reflections you perceive as a user. This is also referred to as the haze level. The value of the haze level indicates the degree of anti-reflectivity of a display as a percentage.

Why does the haze level vary from display to display and why do displays need to be anti-reflective at all? Here you can find out more about the importance of display reflections.

 

What is the haze level?

The term „haze“ comes from the English language and means „haze“ or „fog“. The haze level therefore describes the scattering behavior of light of a material. For displays, the value indicates how well the display is anti-reflective. The following applies: The higher the value, the better. Non-reflective displays have a haze level of 0%. Currently, the maximum anti-reflective coating is 44%.

 

Why anti-reflective coatings?

Reflections significantly impair the viewing experience. Reflections on the display are annoying and should therefore be avoided as far as possible. A high haze level is therefore particularly useful for touch displays, whose surfaces are usually made of glass. But a high haze level also makes sense for all other displays, as the image is easy to read even in bright rooms and in strong sunlight.

 

Disadvantages of a display anti-reflective coating

Some manufacturers do not use anti-reflective coating, as this is always accompanied by a slight deterioration in the contrast value. The perceived resolution can also be affected by a high haze level. Furthermore, an anti-reflective coating causes additional costs in production as the glass has to be chemically treated. Displays with a high haze level are therefore usually somewhat more expensive.

 

Defog the display yourself

You can usually remove unwanted reflections from your display yourself. Unwanted light reflections can be removed quickly and easily with the help of so-called anti-glare films. The latter should only be applied to thoroughly cleaned surfaces. Air bubbles can be easily pressed out with a credit card. Anti-reflective films are already available in stores from around ten euros.

However, we recommend investing directly in a sensible display with a higher haze level. This applies in particular to professional users and devices in conference rooms.
