TAINAN, TAIWAN, 2 December 2025 – Pervasive Displays Inc. is pleased to announce the release of Pervasive Displays Library Suite (PDLS) version 10.0.0. This is the latest major update to its library suite for driving e-paper displays and building embedded GUIs on Pervasive Displays e-paper panels.
This release introduces multilingual support and performance enhancements for embedded systems using e-paper technology.
About PDLS
The Pervasive Displays Library Suite (PDLS) is specifically designed for the Pervasive Displays e-paper displays (EPDs), extension boards and evaluation kits. It provides a high-level interface to drive the EPDs with both normal and fast update, supports capacitive touch and haptic feed-back. It is developed in C++ and can easily be ported to any SDK.
It also includes advanced libraries for graphics (clock, gauge, histogram), GUI elements (label, button, check-box, slider, keyboard), bar- and QR-codes, file storage for pictures, and serial output for header files. Watch this YouTube video with EPDK kit to demonstrate the rich elements.
What’s new in version 10.0.0
With this major release, PDLS introduces several important enhancements to meet next-generation embedded GUI and multilingual text requirements.
- UTF-8 support – PDLS 10.0.0 now fully supports UTF-8 encoded text across all modules, enabling developers to render international text in multiple languages in a single application.
- 16-bit multilingual font engine – The font subsystem has been upgraded from 8-bit to 16-bit wide glyph indices. This significantly expands the character set available. This opens new applications requiring non-Latin character sets like Chinese, Japanese, Arabic, Hebrew as shown above.
- Backward compatibility and migration path – The new version retains the previous API for text and graphics primitives, as well as advanced graphics and GUI controls. New font features are additive — no breaking changes. The technical note Migrate from release 9 to release 10 provides a transition path to existing applications built on prior releases.
- Improved performance and memory usage – Under the hood, version 10.0.0 brings optimizations for font caching, reducing the memory footprint up to 33% compared to previous release. A technical note explains how to optimize the size of the 16-bit fonts.
- Enhanced documentation and sample projects – The Knowledge Base, the User Guide and the Reference Manual have all been updated. They now include examples for multilingual rendering and GUI construction.
