Non-glare finish for optical displays

26 June 2013 Opto-Electronics

According to Instrument Plastics, an effect that has been highlighted by new TFT displays is the specular interference on the non-glare surface of EMC display filters. This is caused by optical interference between the pitch of the pixels and the size of the peaks and troughs of the non-glare surface. When this occurs, a colouration and sparkle effect can be seen on a plain white screen, which is then magnified when colours are introduced on the display.

This interference can cause confusion for operators working with map systems or any information displays with moving fine details.

Instrument Plastics has developed the L70 non-glare finish, which cuts down surface reflections so the display can be used in high-brightness environments, and eliminates specular interference giving superior optical clarity for ease of reading the display.

The L70 finish can be used in conjunction with Optolite HSR to increase contrast by passing the wavelengths of light from the display whilst partially absorbing other wavelengths of ambient light. Selected Optolite colours are available which are matched to the transmission characteristics of the display, with a proven track record among handheld instruments and rugged displays in a variety of military environments.
