As Digital Signage and Wayfinding kiosk are widespread in modern life, we can find their images in every corner around us. These digital signage and kiosk are mainly equipped indoor or outdoor of government place, corporate, school, hospital, bank, shopping mall, transfer hub, etc.
The readability is vital for the digital signage and kiosk display, but sunlight and high brightness is unavoidable. Then we use Anti-Glare or Anti-Reflective technology glass to help us read the info clearly, quickly, and comfortably (minimal eyes-train). Both anti-glare and anti-reflective technologies improve readability, but they use very different methods to improve display readability.
What is Anti-Glare Glass?
Anti-glare technology is a treatment method on glass coating by dealing with external sources of reflection off a surface (like bright sunlight or high ambient lighting conditions), to reduces the effect that these reflections have on the readability of the digital signage and kiosk display. The overall objective is to reduce the interference of reflected images to improve the visibility of the display.
However, the diffusion of light using anti-glare technology leads to the scattering of light rays, resulting in a reflection output of approximately 8%, which can affect screen visibility from certain angles. As a result, anti-glare technology is generally used for outdoor displays or for indoor areas that have bright, intense lights whenever a loss in image quality isn’t much of an issue. However, which is not recommended to be used in dimly light areas since the blurriness/graininess of the coating will be much more obvious.
What is and Anti-Reflective Glass?
Anti-reflective technology is designed to minimize reflections by disrupting the energy contained in light waves, causing them to flow out of sync. The disrupted wave pattern virtually eliminates all reflection from the acrylic surface, resulting in a crisper image and true-to-life colors. The scientific term for this phenomenon is the destructive interference of light. Additionally, anti-reflective glass coating does not consider only external light sources, but rather both internal and external ones.
Anti-reflection technologies do not cause the scattering of light rays, resulting in less reflection output and reduced glare. Therefore, outdoor digital signage and kiosk display visibility is greatly improved, regardless of the angle at which a display is viewed.
Which technology is better?
In comparison with anti-glare glass, anti-reflective glass reduces reflection output to approximately 8%, anti-reflective technologies can reduce reflection output to as little as 0.4%. Also, when using anti-reflective technology, total light output from a screen can be increased to 99%. Which provides the best solution for improving screen clarity in bright locations.
However, anti-glare coatings are economical, and do reduce the impact of screen glare compared with having no solution at all, even if it’s only up to a certain level. Anti-reflection solutions are often more expensive. Due to the big difference in cost, anti-glare technology is used more on indoor & outdoor sunlight readable digital signage displays.
Which is Right for Your Customer?
As a money saving solution, anti-glare is the best option. If the cost is no problem, and you want to expand the brand and win more market, the anti-reflective is the sensible choice. RACVISION supply with both of anti-glare and anti-reflective technology digital signage/kiosk display. We will recommend the ideal solution for your according to your reality requirements.
