Research and Design of Graphic Display Technology for Embedded Devices Based on Ultra-Lightweight JavaScript Engine

This study proposes a graphics rendering technique based on an ultra-lightweight JavaScript engine for resource-constrained embedded devices such as ESP32. The technique achieves efficient image rendering by integrating generic low-level interfaces. The paper investigates and designs a modular system architecture that improves performance through interpreted execution of JavaScript, just-in-time (JIT) compilation, and optimized memory management, while supporting high concurrency and asynchronous I/O scheduling. Experimental evaluation shows that compared to traditional techniques, the system demonstrates significant advantages in graphics rendering speed, various types of graphics display, and resource efficiency. This study bridges the gap between the demand for high-quality graphical user interfaces (GUIs) and resource constraints in Internet of Things (IoT) devices to some extent.
