Three-dimensional display device

Abstract

A three-dimensional display device comprises a flat display panel and an image-converting sheet disposed on or above the display panel. The display panel comprises a matrix of unit display cells arranged as rows and columns and where the cells are spaced apart to have respective row and column direction pitches. The image-converting sheet comprises a plurality of inclined lenticular lenses where the inclination is set according to the row and column direction pitches so as to reduce perception of Moiré patterns when stereo-scopic images are projected through the image-converting sheet to an observer viewing the display panel as an upright panel having respectively different left and right stereo-scopic image projections.

Description

PRIORITY STATEMENT[0001]This application claims priority to Korean Patent Application No. 2009-0083170, filed on Sep. 3, 2009, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which application are herein incorporated by reference in their entirety.BACKGROUND[0002]1. Field of Disclosure[0003]The present disclosure of invention relates to a three-dimensional display device. More particularly, the present disclosure relates to a three-dimensional (3D) display device of a lenticular type.[0004]2. Description of Related Technology[0005]As demand increases for providing three-dimensional stereo-scopic images in the animated display industry such as in the computer game industry, the movie industry and so, attempts to provide a practical 3D display device capable of displaying three-dimensional animated images is ongoing. In one approach to 3D imaging, two different 2-dimensional (2D) images are provided to the left and right eyes of an observer so that a corr...

AI Technical Summary

Benefits of technology

The present patent provides a three-dimensional display device that reduces the occurrence of Moiré patterns, improves resolution, and enhances the three-dimensional perception effect. The device includes a display panel and an image-converting sheet with inclined lenticular lenses. The lenses are inclined in relation to the data lines and the pixel electrodes, which are connected to the switching elements. The inclination of the lens axis is defined by dividing a distance between adjacent unit cells in the second direction. The display panel includes a plurality of unit cells with pixel electrodes disposed within an area defined by crossing gate lines and data lines. The image-converting sheet is placed on top of the display panel and includes a plurality of lenticular lenses with inclined lens axes. The ratio between the first and second pitches is about 1:1.5. The display device can be easily manufactured and used as a portrait or landscape type display device without changes of structures.

Problems solved by technology

In a certain viewing position, the observer may recognize repeated block patterns of the pixels and as a result may not perceive the desired 3D images.
