AGC develops anti-glare screens

A Japanese glass manufacturer has developed anti-glare TV screen glass for 4K high-definition displays, notebook PCs and similar devices.
AGC, based in Tokyo, reduces glare (best described as random unevenness on a screen caused by optical factors) as well as supressing light reflection.
Anti-glass (AG) glass reduces eye fatigue by adding unevenness to the glass surface to reduce reflections, and is mainly used as cover glass for displays installed in PCs, tablets, and other products. In product development, it is difficult to satisfy all three optical characteristics of anti-reflectiveness (suppression of light reflection), clarity (clear images), and anti-glare property (suppression of random unevenness on the screen). Especially with HD displays, optical interference with the LCD panel becomes stronger and causes glare to worsen.
AGC says it has now developed a new type of AG glass with more uniform unevenness on the glass surface through a special mechanical process. While maintaining the same level of anti-reflective performance as its conventional products, reducing glare has been an issue, but this new glass cuts glare by approximately 30 per cent and reduces eye discomfort when viewing HD displays.
