Pervasive Displays is sampling four small, high-resolution three-color TFT active matrix Electronic Paper Display (EPD) modules with internal timing controllers. The new additions to the range are the 1.54-inch (E2154FS091), 2.13-inch (E2213FS091), 2.66-inch (E2266FS092) and 2.71-inch (E2271FS091) EPD modules. They promise to accelerate time to market by integrating a chip-on-glass (CoG) timing controller to simplify the product design process.
In addition to the integrated timing controller, the chip-on-glass design includes a booster circuit and makes possible a remarkably thin profile EPD. The slim size of the panel enables a smaller product form factor and allows for larger batteries in mobile applications.
The EPD modules are based around TFT active matrix three-pigment, black, white, and red E Ink display panels. Each display’s pixel density of 103 dpi provides crisp, clear text and graphics. The technology provides a natural light-readable display which, due to its bi-stable nature, requires very little power to update an image and no power to maintain the image. Depending on application demands, the modules can operate for extended periods of weeks or months on a single small battery.
