no. 1 approach

[0107] In the two-dimensional display used in the present invention, in order to realize color display, three kinds of color pixels corresponding to the three primary colors of RGB are two-dimensionally arranged in the vertical direction and the horizontal direction. In the first embodiment of the present invention, a stripe configuration is used for description. The stripe configuration is such that the three color pixels corresponding to the RGB three primary colors are arranged with the same color pixels in the vertical direction, and the RGB color pixels are arranged in the horizontal direction. Color pixels are periodically arranged. In the following description, three types of RGB are used as color pixels, but the concept of the present invention can also be used in cases other than three types, for example, four types.

[0108] Examples of the two-dimensional display having a color pixel structure used in the present invention include, but are not limited to, liquid cry...

no. 2 approach

[0152] In the above description, the case where the three color pixels corresponding to the three primary colors of RGB are arranged in stripes has been described. As an arrangement of color pixels, an oblique color pixel arrangement in which color pixels of the same color are slanted in an oblique direction is also conceivable, and the second embodiment of the present invention will be described using this arrangement.

[0153] Fig. 13 shows the relationship between the arrangement of oblique color pixels and the horizontal distance from the central axis of the cylindrical lens to the center of the color pixels in the second embodiment of the present invention. When considering color pixels of the same color, the horizontal distance changes p between the closest color pixels whose vertical positions differ by 1 pixel x -p y tan theta. The change in horizontal distance N(p x -p y tanθ) is equal to the change 3p of the horizontal distance of the same color pixel on the same...

no. 3 approach

[0171] The basic configuration of the three-dimensional display according to the third embodiment of the present invention is the same as that of the first embodiment of the present invention. Thus, the relationship between the horizontal pitch and the vertical pitch of the color pixels of the two-dimensional display, the inclination angle θ of the central axis of the cylindrical lens, and the number of color pixel groups related to the horizontal row and column of the cylindrical lens The formula is the same as that of the first embodiment of the present invention.

[0172] However, the three-dimensional display 50 according to the third embodiment of the present invention has an aperture array 30 provided between the two-dimensional display 1 and the lenticular sheet 3 as shown in FIG. 16 . Here, the opening array used in the present invention may use a metal film such as a chromium mask, but is not limited thereto. Alternatively, black stripes made of light-absorbing mater...

Abstract

The invention provides a three-dimensional display capable of eliminating color non-uniformity and intensity non-uniformity on a three-dimensional image. The three-dimensional display comprises: a two-dimensional display, which comprises a plurality of color subpixels arranged in rows extending in a horizontal direction and in columns extending in a vertical direction which is substantially perpendicular to the horizontal direction, the color subpixels of red, green and blue being arranged periodically in the rows and the color subpixels of the same color being arranged in the columns; and a lenticular sheet provided on the two-dimensional display and having a plurality of cylindrical lenses through which the color subpixels are viewed and which extend in parallel with one another, the central axis of each cylindrical lens being inclined at an angle of theta to the column of the two-dimensional display, wherein, when a pitch of the color subpixels in the horizontal direction is px, a pitch of the color subpixels in the vertical direction is py, and a color subpixel group constituting one three-dimensional pixel is constituted by 3M*N number of color subpixels where 3M is the number of color subpixels in each row of one of the cylindrical lenses and N is the number of color subpixels in each column of one of the cylindrical lenses, a relationship, theta = tan -1 (3px / NPy ), is satisfied.

Description

technical field [0001] The present invention relates to a three-dimensional image display method, in particular to a three-dimensional image display using a lenticular sheet. Background technique [0002] At present, the display method of the three-dimensional display is a binocular stereoscopic display method as the mainstream. It is based on the principle that different images are displayed in the left and right eyes, so that people can obtain a three-dimensional effect. In the binocular stereoscopic display method, there is a disadvantage that the observation direction of an object does not change when a person moves his head, that is, there is no motion parallax. In addition, the focusing of the eyes, that is, the focusing falls on the screen on which the image is displayed, which is inconsistent with the display position of the three-dimensional object. This contradiction is the cause of eye fatigue when viewing a three-dimensional image. [0003] Three-dimensional d...
