Comprehensive Review and Meta-Analysis of Naked-Eye Light Field Display Technology Utilizing Mini/Micro LED Panels

The article provides an in-depth exploration of the concept and principles behind light field (LF) display technology, tracing its origins to Alexander Gershun’s 1936 proposal of spatial radiation described by three-dimensional vectors. The discussion highlights the evolution of the light field model, from early formulations to the contemporary four-dimensional model that simplifies light ray representation for human perception. It categorizes light field displays into two broad types based on their generation techniques: those utilizing light source control and those employing surface light modulation, detailing their respective mechanisms, advantages, and limitations. Significant advancements in integral imaging, compressive light field displays, and diffraction-based systems are reviewed, alongside challenges such as resolution constraints, image crosstalk, costs, and viewing comfort that hinder commercial adoption. The article stresses the potential of light field technology in creating immersive 3D visual experiences and anticipates future innovations focusing on hardware enhancements and the integration of advanced algorithms.
