The sharp displays of our smartphones with higher-resolution and pixel density usually consume a large chunk of your smartphone battery even while checking the smallest of the details. Due to this, smartphone makers like YotaPhone are planning to have an alternate e-ink display that would display different information not requiring the screen to turn on every time. Case maker popSLATE has arrived with a very similar solution for this.
The popSLATE case is a protective case that is made up of 4inch shatter proof e-ink screen that acts like a display. the case has been designed for the latest iPhone 6 and the e-ink display would be placed to the back of your iPhone and would allow you to customize it with any map, photography or screenshot over the Bluetooth. The images would appear on the grey scale and a dedicated app or a dedicated button allows you to swap over the last 8 images.
This case has a 240mAh of battery of its own and can be charged through the microUSB itself. popSLATE is said to add more feature to its case in the future which could display information automatically based on the time of the day and your location. Check out the source link below to get more details for its cases. Take a look at the images below.
