• What is sunlight readable, daylight viewable?

A sunlight readable or daylight viewable monitor is also known as a high brightness monitor. It is designed to operate in very bright environments, for example in broad daylight. High brightness monitors are typically used commercially in kiosks and out-of-home advertising.

Keewin recommends screens with a brigthness rating of at least 2,500 for applications in high ambient light locations, and 5,000 nits for applications in direct sunlight.

• Can Keewin high brightness LCDs be used outdoors?

With daylight viewable capabilities, Keewin high brightness screens are great for outdoor applications such as kiosks and building facades. For outdoor installations a weatherproof enclosure is required. In many instances, this may include the use of an air conditioning system.

• What is the difference between a professional and commercial display?

Unlike consumer television sets, professional displays are designed to run 24 hours a day, 7 days a week with advanced heat management systems. Built with security in mind, they offer rugged metal construction and the ability to lockout remote control functions. While televisions are limited to being mounted in a landscape orientation, professional displays may also be mounted in a vertical, portrait orientation. Perhaps most importantly, consumer televisions are not covered by warranty when used in a commercial environment.
