Lotus Glass, which, as the name suggests, is thinner and allows for more light to come through, thus reducing the power consumption requirements of the backlight in the case of LCD, and lowering reflectance in the case of OLED displays.Corning, the maker of Gorilla Glass, have developed a new generation with its proprietary fusion process, called
over 30 layers of special film with nanometers thickness on each side, the researchers have managed to achieve the so-called "invisible glass", i.e. one that reflects almost no light, so you don't even know it's there.
Modern smartphones and tablets' glasses reflect about 8% of the light that passes through them, making for unpleasant glare and/or reduced visibility in direct sunlight. Better relfectance ratios are in phones with Super AMOLED displays - less than 6% - which contributes to outside visibility being on par with their brighter LCD counterparts.
