AGC : Develops Anti-Glare Glass for 4K HD Displays

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 extremely 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. Overcoming this problem is a challenge.

AGC 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% and reduces eye discomfort when viewing HD displays.

The new AG glass will be exhibited at AGC's booth at CES 2023, one of the world's largest technology and innovation trade fairs, to be held in Las Vegas, the U.S., on January 5-8, 2023. Please see the following press release for details of AGC's other exhibits at CES.

Cosmetics
Pros	● High contrast and image clarity	● Less reflection leads to reduced eye fatigue
Cons	● Large light reflection	● Reduced image sharpness ● Reflected light becomes whitish and colors (especially black) become whitish ● Occurrence of glare* *Approximately 30% improvement in the product announced today (compared to AGC's conventional products)
