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 Wide-Temperature small-sized 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 Wide-Temperature medium-sized 5.81" and 7.4" screens
• Pervasive_BWRY_Small for small-sized 1.54", 2.13", 2.66", 4.2" Spectra 4/BWRY/four color type screens

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_EXT3_Basic_Touch for Pervasive Displays iTC monochrome touch-screens with EXT3-Touch 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)
