E Ink Technology
Founded by Chilin Technology (the display systems business within the Chi Mei Group) Pervasive Displays Inc. (PDI) is a pioneer in the area of industrial e-paper displays using E Ink imaging film to deliver ultra-low-power panels in a variety of sizes from a 1.44" e-tag to a 10.2" tablet. By partnering with E Ink, the industry leader in e-paper film, PDI's produces "electrophoretic displays" that are bistable in nature – i.e., they require no power to maintain an image on the screen.
Pervasive Displays E-Paper Module
PDI assembles e-paper modules by adding the E Ink film on top of Chilin's active-matrix TFT backplane and then covering it with a protective sheet. The panel is driven by PDI's chip on glass ICs and timing control software, which is stored and executed on a micro controller on the attached printed circuit board.
