Abstract

This study evaluates projector imaging quality and its impact on students' reading effectiveness through experiments in multiple classrooms. Using a nine - point grid method, it analyzes illumination distribution characteristics of projectors. Results show significant differences in illumination uniformity and stability among projectors. Uneven illumination can increase visual fatigue and reduce reading efficiency. When edge - center illumination difference exceeds 100 lux, reading speed drops by 15% - 20%. Projector aging also reduces contrast and color gamut coverage, affecting character recognition. The study introduces a multi - dimensional evaluation method and develops an intelligent analysis platform, providing a scientific basis for projector selection, maintenance, and use in educational institutions to optimize teaching environments and enhance learning outcomes.
