46‐3: A Design of Autostereoscopic 3D Display Based on High PPI OLED Screen

By compressing the effective emission area of OLED (Organic Light‐Emitting Diode) pixels, it is possible to enhance the PPI (Pixels Per Inch) of the screen without increasing the risk of color mixing, thereby improving the resolution of autostereoscopic 3D displays. However, excessively large pixel pitches can lead to dark zones between viewpoints, which can impair the presentation of motion parallax. This paper proposes a design method for autostereoscopic 3D displays using OLED screens. By employing a large‐angle oblique lenticular lens array and reducing the horizontal spacing between viewpoints, the width of the viewpoints generated by each subpixel is expanded, thereby eliminating dark zones between viewpoints and avoiding abrupt brightness changes. Based on this approach, a lenticular lens array with an oblique angle of 78.3° was attached to an 800‐PPI OLED screen, achieving a field of view of ±25° and delivering autostereoscopic 3D displays with good image depth and smooth motion parallax, which demonstrates the feasibility of the design.
