Pervasive Displays Inc. designs, manufactures and markets e-paper displays (EPD) for applications requiring high resolution, good readability and low power consumption. Pervasive Displays focuses on commercial and industrial applications and is the world leading vendor with most experience in E Ink e-paper technology.

The following drivers provide a quick example with built-in images for test. PDLS Common is required to use these drivers.

• Pervasive_Wide_Small for small-sized, monochrome/BW, wide-temperature 1.52", 1.54", 2.06", 2.13", 2.66", 2.71", 2.9", 3.70", 4.2" and 4.37" screens
• Pervasive_Wide_Medium for medium-sized, monochrome/BW, wide-temperature 3.4", 5.81" and 7.4" screens
• Pervasive_Wide_Large for large, monochrome, wide-temperature screens, with built-in images for test
• Pervasive_BWRY_Small for small-sized 1.54", 2.06", 2.13", 2.66", 4.2", 4.37" Spectra 4/BWRY/four color type screens
• Pervasive_BWRY_Medium for medium-sized 5.8" and 7.4" Spectra 4/BWRY/four color type screens
• Pervasive_BWRY_Large for large-sized 9.7" Spectra 4/BWRY/four color type screens
• Pervasive_Touch_Small Hardware driver for small, monochrome, touch-enabled screens

For BWR/Spectra models, you may either choose from the EPD_Driver_GU drivers or PDLS_EXT3_Basic_Global

The Pervasive Displays Library Suite is specifically designed for the Pervasive Displays screens and boards. It provides the text and graphic primitives for all the screens and supports capacitive touch on touch-screens.

• PDLS_Common provides a light hardware abstraction layer with C-like syntax for C and C++ SDKs. It is required by the drivers and the PDLS library.
• PDLS_Basic for Pervasive Displays with wide temperature and embedded fast update (film K) and four color (film Q) with EXT3.1 extension kit
• PDLS_EXT4_Basic_Matter for Pervasive Displays E-Paper Development Kit for Matter (EPDK-Matter) and monochrome screens with wide temperature and embedded fast update (film K)
