THREE-DIMENSIONAL IMAGE DISPLAYING DEVICE AND THREE-DIMENSIONAL IMAGE DISPLAY

摘要

A three-dimensional image displaying device is provided. The three-dimensional image displaying device includes an element image array, a backlight source, and a pinhole array. The light reinforcing structure is disposed on the back side of the pinhole array for increasing the light extracting rate of the pinhole array. The light extracting rate of the pinhole array is raised by disposing the light reinforcing structure on the back side of the pinhole array, and therefore the display brightness of the three-dimensional image displaying device is increased.

主权项

1. A three-dimensional image displaying device comprising:
an element image array including a plurality of pixel cells for displaying three-dimensional scene information; a backlight source for providing the element image array with a display light source to reconstruct a three-dimensional scene in a display area; and a pinhole array including a plurality of pinholes for transforming light emitted from the backlight source into scattered light of a point light source; wherein a light reinforcing structure is disposed on a back side of the pinhole array for increasing a light extracting rate of the pinhole array, the back side of the pinhole array is a side of the pinhole array facing the backlight source, the light reinforcing structure is a reflective film disposed on the back side of the pinhole array, and the reflective film is a metallic high-reflective film or a bubble polymer film disposed in a non-pinhole area of the back side of the pinhole array.
