The traditional Digital signage has extremely low visibility under sunlight, and even the shadow of the reader can be seen, which seriously affects the reading experience.
In order to solve this problem, Terminal proposed to add a piece of Anti-Reflective glass in front of the glass. The reason for this is that the sun produces a lot of ultraviolet rays, which have no poor absorption capacity in the screen, and are directly reflected to the outside.
Anti-Reflective glass is also called anti-reflective coated glass and anti-reflection glass. It uses magnetron sputtering to apply anti-reflective coatings on both surfaces of white glass or ultra-white glass. The reduction of light from 8% to less than 1% can reduce the reflection and glare of electronic video screens and image screens under environmental conditions, and greatly improve the contrast and clarity of flat panel displays in strong light environments.
Anti-reflection coating (anti-reflection coating) is deposited on the optical surface to reduce the specular reflectivity. The anti-reflection coating consists of a single layer or multiple layers. The design of the anti-reflection coating is optimized to destructively interfere with the reflected light. This design method will achieve the maximum amount of light transmission without affecting the image quality.
After repeated tests of Terminal, the results are as follows:
We added an extra layer of Anti-Reflective glass from the original LCD display, which greatly increased the effect.
The comparison effect is as follows:
