Overcoming Problems Setting Up Digital Signage

By | March 3, 2010

When considering where to locate a kiosk outside, one main problem to overcome is sunlight. This causes glare on the screen rendering the advertisement useless! Any one who has ever tried to use a laptop or watch television outside will understand how frustrating it is. The brightness of the sun impacts upon the visibility of the screen. If the image can not be clearly seen, then the investment of a business’s capital is wasted.

Outdoor screens need to be brighter than indoor units. Compared to an average indoor digital signage screen, featuring a brightness measurement of 350 to 600 nits, an average television set has a measurement of 450 to 500 nits. The recommended bare minimum for outdoor digital signage should be a brightness measurement of between 1,500 nits and 2,000.

Increasing the brightness may be important; however increasing it beyond a certain level may cause the image to become indistinguishable. The image is bright, but it becomes difficult for a person to tell what is on the screen and the image does not catch the consumer’s attention.

This is where controlling the reflection is required. The image displayed on the cover glass may become that of the audience or their surrounding area. Using anti-reflective treated glass reduces the unwanted reflection and enhances the image.

Some products can achieve a 50% reduction of the sun load and beyond 90% of harmful UV rays. Also, it promotes an increase of the image contrast and colour spectrum. This has been likened to human sunscreen protection, but for LCD’s.

Sunscreen protection for LCD’s can also be called an outdoor LCD enclosure.
