TECHNOLOGY

Outdoor LCD enclosure market is quite confusing with many suppliers offering solutions of much different quality to system integrators and end customers. It is important to better understand requirements of electronics to be able to differentiate between options and evade danger of wasting resources.

UNDERSTANTING VISIBILITY AND RETHINKING TECHNICAL SPECIFICATIONS

There are three factors influencing on sunlight readability quality:

LCD panel luminance output* LCD panel contrast performance Front glass anti reflective treatment
*dependent of inner enclosure temperature    












Note that all technical specifications for OEM LCD panels are true only in pitch black room. All the measurements for tech specs are done in best conditions of 25 ± 2°C, which do not apply especially for most outdoor LCD systems. Hence, performance in real life is worse. Not only because of inner enclosure temperatures, but also because of sun visible light will reflect from screen decreasing difference between whitest and darkest pixels.

This is especially true if we are talking about direct exposure. Full moon night white illumination is 0,15 nit while noon day time illumination is mind boggling 96.000 nits, that being without objects in vicinity reflecting some more luminance into screens. What do we need: As much as possible of LCD luminance and contrast performance with quality anti reflective glass treatment allowing as much as possible of visible light passing through. This together with quality glass treatment minimally reflecting visible light will deliver well readable images throughout the day.
