Abstract

A three-dimensional image display includes a liquid crystal display panel, a lenticular layer, and a backlight module, wherein the lenticular layer is disposed on the liquid crystal display panel to separate images generated by the liquid crystal display panel. The backlight module includes a light emitting device and at least one brightness enhancing film. The liquid crystal display panel accepts light from the backlight module and generates a plurality of images. Prisms and lenses are disposed on the brightness enhancing film and the lenticular layer, respectively, wherein orientations of prisms and lenses cross each other. The three-dimensional image display makes the traveling direction of light more perpendicular to the surface of liquid crystal display panel in order to reduce the crosstalk between adjacent images.

Claims

1. A three-dimensional image display, comprising:

a display panel;

a lenticular layer including a plurality of lenses disposed on a first surface of the display panel, wherein the lens has a first orientation; and

a backlight module including at least one first brightness enhancing film disposed on a second surface of the display panel opposite to the lenticular layer, wherein the first brightness enhancing film includes a plurality of first prisms having a second orientation;

wherein a reference angle θ

exists between the first orientation of the lens and a first side of the display panel, a first angle exists between the second orientation of the first prism and the first side of the display panel and the first angle is between (70+θ

)° and

(110+θ

)°
