Near-Eye Light-Field Display with Time-Division and Color Multiplexing to Induce Focal Accommodation

In this paper, we propose a high-resolution, full-color light-field display using a super-multiview method capable of presenting parallax in both horizontal and vertical directions. Our objective is to project nine full-color views to the viewer's eye, generating parallax effects. To achieve this, we introduce a method that involves generating nine viewpoints through nine-fold time-division and color multiplexing. This method utilizes 3.1-inch LCD panels with a refresh rate of 120 Hz. Additionally, we have reduced the size of the display system to a hand-held size, intending to develop a head-mount display. Our proposed method not only reproduces the natural blur effect when the image is defocused but also successfully induces focal accommodation in observers. To validate our approach, we conducted measurements of focal responses using a refractometer. The experiments confirmed the effectiveness of our method in inducing focal accommodation.
