Embodiment Construction

[0058] Figure 8 illustrates the installation of the display 40 in a relatively narrow car 41 and a relatively wide truck. The multi-view display is of the dual-view type and is illustrated as comprising a liquid crystal display (LCD) 43 having alternating columns of pixels displaying alternating vertical bands of L and R images of a left viewer and a right viewer. The distance between the parallax optic in the form of a lenticular screen 44 and the pixel plane of the LCD 43 is the thickness of the LCD substrate and associated layers, in this example approximately 0.7 mm. The display is of the front parallax optic type, but in the case of all the embodiments described hereinafter it may also be of the rear parallax optic type.

[0059] The optical system 45 is arranged in front of the lenticular screen 44 and comprises diverging lenses in the form of plano-concave lenses, the lenses or lenticular layers of the lenticular screen 44 being plano-convex lenses. The combination of ...

Abstract

A multiple view display comprises a display device which displays first and second images in a spatially multiplexed fashion across the display surface. The device cooperates with a parallax optic such as a lenticular screen so as to act as a directional display sub-system directing light from the first and second images in different viewing directions. An optical system, for example comprising a lenticular screen of diverging elements, changes the angular separation of the viewing angle directions, for example so as to increase the angular separation.

Description

technical field [0001] The present invention relates to a multi-view directional display that displays two or more images such that each image is visible in a different direction. Thus, two or more viewers looking at the display from different directions will see different images from each other. Such a display may be used, for example, in an autostereoscopic or dual view display. Background technique [0002] For many years, conventional displays were designed to be viewed by multiple users simultaneously. The display characteristics of the display are made such that a viewer can view the same superior picture quality from different angles relative to the display. This is effective in applications where many users require the same information from the display, such as displaying departure information in airports and train stations. However, there are many applications where individual users want to be able to see different information from the same display. For example,...
