Three-dimensional-two-dimensional mixed display system using integral imaging with an active pinhole array on a liquid crystal panel
ABSTRACT A display system that simultaneously displays two-dimensional (2D) and three-dimensional (3D) images using a pinhole array on a liquid crystal (LC) panel is proposed. Using the transparent structure of the LC panel, the system can generate or eliminate pinholes electrically and can display a 3D image in a selectable specific area of the display panel, while 2D images are displayed on the rest of the screen. An analysis showing the advantages and limitations of the proposed system is provided. Finally, the proposed principle is proven by experimental results.

ABSTRACT: We proposed a method to fabricate large area uniform microlens array with a wide range of focal length for integral imaging. A thin hydrophilic layer with matrix array of circular holes was first fabricated on flat substrate by photolithography. A hydrophobic layer was then imprinted on top of the hydrophilic layer. By filling a very low viscosity prepolymer material into each circular hole via drop-on-demand printing, refractive lens with spherical shape was self assembled by force of surface tension. An integral imaging system using the proposed microlens array was demonstrated by closely placing object to the microlens array. The good image quality indicates that the proposed polymer microlens array has potential applications in three-dimensional displays.Displays 12/2010; 31(4-5-31):186-190.
