Benefits of technology

[0012]In the present invention, the modulatable electrowetting grating is used to make the display panel achieve the three-dimensional displaying effect, so as to reduce image phase retardation compensation procedure, and to reduce the cost.

Problems solved by technology

The stereoscopic-type three-dimensional display technology has been mature, and it has been widely used on certain special applications, for example, military simulations or large-scale entertainments etc.. However, due to the factors of being inconvenience and less comfortable, it is difficult for the stereoscopic-type three-dimensional display technology to become popular.
Therefore, a complex optical compensation design is required for the conventional three-dimensional image display.

Embodiment Construction

[0023]FIG. 2 shows a three-dimensional display device according to the present invention. Referring to FIG. 2, a three-dimensional display device 200 includes a display panel 210 and a modulatable electrowetting grating 220. The display panel 210 has a plurality of pixels P. The display panel 210 is, for example, a liquid crystal display panel, a plasma display panel, or an organic light emitting display panel, and the liquid crystal display panel is used as an example for illustration herein. For example, each pixel P includes a red sub-pixel PR, a green sub-pixel PG, and a blue sub-pixel PB. The modulatable electrowetting grating 220 is disposed on the display panel 210, and has a plurality of electrowetting light valves 230 corresponding to the pixels P. It should be noted that, as shown in FIG. 2, each electrowetting light valve 230 has an opaque hydrophobic flowing medium 270, and each electrowetting light valve 230 generates a transmissive state T and a shading state S through...

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 96137460, filed on Oct. 5, 2007. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a display device. More particularly, the present invention relates to a three-dimensional display device capable of displaying three-dimensional images.[0004]2. Description of Related Art[0005]As for the development of display technology, besides the development trend of being light, thin, and small, an object of displaying a three-dimensional image is also expected. Recently, three-dimensional display technologies can be approximately divided into a stereoscopic type that requires the viewers to wear specially-designed glasses and an auto-stereoscopic type directly viewed with naked eyes. The stereosc...
