Pervasive Displays unveils e-paper extension kit and evaluation board Pervasive Displays has introduced the EXT3 extension kit and evaluation board, with support for its entire range of iTC ultra-low power e-paper displays. Both the kit and evaluation board are intended for industrial, commercial and retail applications, along with extensive software libraries to help reduce its customersâ engineering effort. According to Pervasive, many manufacturers are looking to move away from TN/STN displays to an ultra-low power e-paper alternative, where the image on screen can be maintained without consuming any power. The EXT3 is intended to help engineering teams evaluate e-paper technology before making system-level decisions. This includes deciding which host microcontroller to use, what screen size and colour to select, and the amount or type of memory needed to deliver an optimum user experience.
