However, if an encoding like this appears to be suitable for 2D screens, as is the case with some LCD screens, where the gaps between pixels and between color units of pixels are noticeable, then conversely it cannot be satisfactorily applied to Plasma screens where the units are in close proximity, or even nearly connected, which may result in noticeable blending of images from different viewpoints

Embodiment Construction

[0037] An exemplary autostereoscopic display device according to the present invention will first be described with reference to FIGS. 2A to 2D.

[0038] The autostereoscopic display device 1 comprises: a plasma screen 2 connected to an electronic module 3 for producing an encoded image; and a lens filter 4 in the form of an array of parallel cylindrical lenses relative to the The vertical axis is inclined by an angle α, the lens filter 4 is arranged in front of the plasma screen at a distance substantially equal to the focal length F1 of the lens, which in a practical exemplary embodiment is 9 mm, while each color cell of the display screen The width is 286 μm.

[0039] The autostereoscopic display device 1 according to the present invention is expected to provide the display of advertisements or information messages at a distance D sufficiently far from the screen, for example greater than 2 m, whereby each eye OG, OD of the observer receives is provided by the lens array 4....

Abstract

A autostereoscopic display device comprises a matrix display screen (2) and a lenticular array (4) which is disposed in front thereof and an lenticular axis inclined with respect to the vertical axis of said display screen (2), wherein said lenticular array (4) is arranged in such a way that it receives and optically processes a raster image transmitted by the display screen, said raster image is encoded for integrating a plurality (P) of viewing points of the same scene, the display screen comprises an array of image pixels each of which comprises three colour cells organised in rows and columns and disposed in such a way that columns of the same colour (R, V, B) are formed within the screen. The image emitted by the display screen (2) is formed by the assembly of three-dimensional pixels (P3D) each of which integrates the plurality (P) of viewing points of the scene pixel image and each three-dimensional pixel (P3D) occupies 3xP colour cells on two adjacent rows within the screen. Said invention is used, in particular for three-dimensional computer and TV set screens.

Description

technical field [0001] The invention relates to a lens autostereoscopic display device. At the same time, it also relates to a method for realizing autostereoscopic display in the device, and a method for synthesizing related autostereoscopic images. [0002] The technical field of the invention is more particularly that of three-dimensional color computer and television screens for example for displaying advertisements or public information messages, or for displaying educational or entertainment content. Background technique [0003] Glasses-free autostereoscopic display devices are known which are realized using parallax barrier technology or lenticular technology. Broadly, autostereoscopic displays include: [0004] - two-dimensional electronic screens using plasma or liquid crystal (LCD) technology for displaying encoded content, and [0005] - 2D-3D conversion screen, which is arranged at a close distance from the 2D screen and works during the transfer, the convers...
