Embodiment Construction

[0023] refer to figure 1 , the display system according to the present invention includes a projector 3 and a support member 4 . A reflector 2 is also optionally provided. Projector 3 comprises one or more light sources which in use are controlled by control electronics to project light 5 onto (in this embodiment) reflector 2 . The reflector 2 is an elongated bar mounted on a structure 1 which may for example be a skyscraper, a bridge, a tower or a free-standing structure. The reflector is preferably mounted vertically to optimize the display effect. In some cases, structure 1 may have components that have reflective properties and that may replace reflector 2 for receiving and reflecting light 5 .

[0024] In the present embodiment the projector light source 3 is a laser diode source capable of emitting in three colors, but could also be a gas laser or other related laser or otherwise a collimated light source and could be formed from a plurality of light sources. A suita...

Abstract

A display system for displaying an image (10) is disclosed. The system comprises a projector (3) comprising at least one collimated light source and a controller (8) for receiving image data and controlling the light source, configured such that, in use, an array of columns of image data representing an image (10) are projected sequentially onto a reflector (2). Due to persistence of vision they appear superimposed on one another when reflected (6) into the eye of an observer (7) and such that, when the observer's eye moves in a direction perpendicular to the direction of orientation of the projected columns the observer (7) can view the image (10).

Description

technical field [0001] The invention relates to a display system. Background technique [0002] Various display systems are well known in the art. These systems can range from simple billboards to more complex image projection and lighting systems. Such display systems have a wide range of applications from providing simple information to more complex image displays and providing advertising content. [0003] While several display system technologies are well established and commonly used, there are often deficiencies associated therewith. For example, while traditional billboard display systems are simple and cost-effective, they are not particularly distinctive. Furthermore, many display systems require large structures to support them and numerous devices for their manipulation and are often highly maintained, especially if the information they display is regularly updated. Especially in the case of display systems that need to display very large scale images, such as...
