With their low power requirements and great outdoor readability, eReader devices based on electrophoretic display technology (EPD) have proven popular with users. But frustrations remain about the lack of colour and video capability. SRD® technology can enable a full-colour and video-capable eReader – that is still easy to read in sunlight and requires limited charging.
For smartphones, the rear of the device could be transformed into an ‘always on’ secondary display. A display highlighting key information and notifications in zero power mode, so extending the time between charges well beyond current smartphone performance.
