Most mobile devices have OLED or LCD displays, but there’s another category of display that has been popular in certain markets: ePaper. This is a very low-power type of display that, as its name suggests, is supposed to be just like paper. E Ink, the company that created ePaper just introduced the latest generation of the technology called E Ink Gallery 3.
Yes, your phone looks amazing with its bright and saturated AMOLED display, but you don’t need beautiful colors or a high refresh rate if you’re just going to read a book. This is where ePaper comes in. It’s a style of display that consumes barely any energy at all. These are placed on eReaders like the Nook devices, and other devices. Recently, Huawei introduced its MatePad Paper.
E Ink Galley 3 ePaper is the next generation of this technology
So, this next generation of ePaper will have some major improvements over the past generations. For starters, this technology supports both back & white and color output. The refresh rate overall has been improved a lot. If the ePaper is displaying in color, it will refresh every 1,500ms while producing the best colors. It can refresh at a maximum speed of 750ms for regular color mode and 500ms for fast color mode.
When it comes to black & white, the numbers are better. When using it in that mode, the screen will refresh every 350ms. That’s about 2.9 times a second. That’s not exactly 120Hz, but it’s perfect for reading. It’s a major improvement over previous versions where it would take more than two seconds to refresh.
When it comes to resolution, it was increased from 150ppi to 300ppi. This should allow text to be crisper. A crisp display doesn’t really matter if you can’t use it. This is why E Ink Gallery 3 can operate in temperatures from 0° to 150° Celsius (32°-122° Fahrenheit).
E Ink Gallery is a major improvement over the previous versions, and it shows. According to the company, it spent more than $100 million on R&D for this new revolution. Not only does this technology consume less energy than other display types, but the manufacturing process produces less CO2 than other technologies. LCD displays produce 50 times more CO2 than ePaper. Paper books produce more than 100,000 times more CO2 than ePaper.
