LED backlight and local dimming

• LED backlight save energy and provide high brightness image than traditional CCFL backlight. And monitor is thinner than before.
• Keewin applied patents for module structure and created high brightness LCD module. Keewin LCD module has well vision under strong light
• Self-dissipation
• Less energy consumption and environment protection
• All metal construction, well dimming

Color, temperature and quality

Ensuring the color and brightness of each screen in a tiled matrix matches can be time consuming and requires additional calibration hardware. Each screen is individually color calibrated to the D65 (6500K) CIE color standard. Not only does this produce a true, natural white, the color of all screens will be uniform.

Q&A

l 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.

2 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.


3 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.
