Mirasol prototype screen measuring 5.1 inches offers 577ppi pixel density
Qualcomm has shown it is still working on Mirasol displays, by demonstrating a prototype screen at SID Display Week in Vancouver, Canada. The 5.1-inch display had a resolution of 2560x1440, giving it a pixel density of 577 pixels per inch, and was accompanied by a 1.5-inch panel used in an "always-on" smartwatch.
The Mirasol technology is a reflective display that relies upon nearby ambient light to be seen instead of a backlight. While Mirasol displays typically lack the brightness of LCD and OLED displays, it does use a sixth of the power, and is an always-on display, making it ideal for mobile devices where power is at a premium, or for e-book readers as a replacement for e-paper technologies.
Though the displays are being demonstrated, Qualcomm is still working on the technology, according to Engadget. The technology is set to undergo research and development for a few more years, and licensees will need to work out how to cut the cost of what has been previously said is an expensive manufacturing process.
