LVGL - Powerful Open-Source GUI Library

Modern User Interfaces for Embedded Systems – efficient, flexible, and resource-friendly.

LVGL (Light and Versatile Graphics Library) is an open-source GUI library specifically developed for embedded systems.

LVGL offers a comprehensive set of widgets, touch support, animations, styling options, and much more – all with very low memory and CPU requirements. This makes the library ideal for processors without a GPU, such as the NXP i.MX 6ULL or NXP i.MX 91, but also suitable for more powerful application processors such as NXP i.MX93 or NXP i.MX 8ULP.

• Open-source (MIT license) – free of charge and flexible in use

• Modern, customizable GUI elements (buttons, sliders, charts, etc.)
  All features: https://lvgl.io/features

• Support for touchscreen operation, multilingual interfaces, and Unicode

• Integrated support for GPU acceleration, e.g. via NXP PXP (i.MX93)

• Easy integration on our modules

Application areas

• Industrial automation: Robust HMIs for machine control
• Medical technology: Intuitive user interfaces for medical devices
• Smart home: Control panels for intelligent home systems
• Transportation: Long-term available passenger displays and ticketing systems
• Compact control panels in building automation
• Information terminals and POS systems
