Will Apple’s Next-Generation Devices Feature Quantum Dot Display Tech?
A recently published patent uncovered by Apple Insider reveals that Apple (NASDAQ:AAPL) has developed a unique method for implementing a cutting-edge technology into its mobile device displays. In the patent titled “Quantum Dot-Enhanced Display Having Dichroic Filter,” Apple described a display design that uses the color-enhancing “quantum dot” technology.
As explained by nanotechnology company Nanosys, so-called “quantum dots” are tiny “nanoscrystal phosphors [that] can actually convert light to nearly any color in the visible spectrum” by changing their size. When pumped with a blue light source, quantum dots are very efficient at producing highly saturated primary colors. According to Nanosys, quantum dot technology makes displays “that are brighter, more efficient, and produce truly vibrant colors.”
In the patent background, Apple noted that, “One of the common issues with quantum dots is that they are potentially toxic.” However, Apple’s patent described a method that might reduce the toxic content of quantum dots by reducing their density. A dichroic filter that would reflect some portions of light would be placed over a quantum dot-enhanced film on an LCD display. According to Apple, the DCF, or dichroic filter, would reflect most of the blue light and reduce the density and toxicity of the quantum dots.
