Autostereoscopic lenticular screen
First Claim
1. In an autostereoscopic display system whereby a lenticular screen is aligned in juxtaposition with a display screen, wherein the lenticular screen has lenticules on one side thereof facing the display screen, wherein the improvement comprises a closed chamber affixed between the lenticular screen and the display screen and a fluid reservoir in communication with the closed chamber and storing an optically clear fluid that is introduced and removed from the closed chamber.

Abstract
An autostereoscopic lenticular screen has a lenticular screen held in juxtaposition with a display surface. The lenticular screen has lenticules disposed on one side thereof and a smooth surface on the other side thereof. In one aspect of the invention, a closed chamber is formed over the lenticules. In order to deactivate the refractive properties of the lenticular screen, and thereby view the display in a planar mode, an optically clear fluid, such as a fluoropolymer, is introduced into at least a portion of the closed chamber. In order to activate the refractive properties of the lenticular screen, and thereby view the display in a stereoscopic mode, the optically clear fluid is removed from the closed chamber. In a particularly preferred arrangement, the lenticular screen is oriented such that the lenticules face inwardly toward the display screen, and the smooth surface of the lenticular screen is coated with an antireflective material.

4. An autostereoscopic lenticular screen apparatus, comprising:
-
a display screen having a display surface, a lenticular screen having lenticules disposed on one side thereof and a smooth surface on the other side thereof, said lenticular screen being held in juxtaposition to the display surface, a closed chamber formed between the lenticular screen and the display surface, a fluid reservoir coupled to the closed chamber, and a transfer valve coupled to the fluid reservoir for introducing and removing an optically clear fluid from the chamber. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A method for switching an autostereoscopic display system between a planar viewing mode and a stereoscopic viewing mode, wherein a lenticular screen having lenticules disposed on one side thereof is aligned in juxtaposition with a display screen, comprising:
-
forming a closed chamber between the lenticular screen and the display screen, introducing an optically clear fluid into a portion of the closed chamber to thereby deactivate the lenticular screen, and removing the optically clear fluid from the closed chamber to thereby activate the lenticular screen. - View Dependent Claims (15, 16, 17)
