Definitions
- a DISPLAY SYSTEM The invention relates to a novel display system, and to in particular illuminated display boards.
- illuminated display boards were essentially display boards with an external light source. For example, a billboard with lights. Smaller displays were generally even less sophisticated and were not even illuminated.
- back-illuminated signs and displays have become very popular.
- This type of system essentially comprises a bank of lights, generally the fluorescent variety with a translucent sheet with the sign applied thereto; either by the way of painting or etching and the like.
- Large banks of lights are often required to illuminate the entire surface of the signs.
- a disadvantage of such back- illuminated signs is that a large number of lights are required, increasing running costs and maintenance costs since they are continually needing to be replaced.
- the entire sign needs to be dismantled, which is a great inconvenience when a large sign is involved.
- the invention provides an illuminated display system comprising at least one transparent sheet having two opposing surfaces, wherein at least one of said surfaces has a matrix of dots substantially covering said surface. Most preferably, each of said surfaces has a matrix of dots substantially covering said surface.
- the invention also provides an article for use in an illuminated display system comprising a transparent sheet having two opposing surfaces, wherein at least one of said surfaces has a matrix of dots substantially covering said surface. Most preferably, each of said surfaces has a matrix of dots substantially covering said surface.
- the invention further provides an article for fixing on to a transparent sheet used in an illuminated display system comprising a transparent film with a matrix of dots applied thereto.
- a transparent sheet used in an illuminated display system comprising a transparent film with a matrix of dots applied thereto.
- the illuminated display system of the present invention with a dot matrix applied to both sides of the transparent sheet provides greater and more even illumination of the sign. This is also true for large signs.
- the prior art does not discuss this important finding and the theory does not predict that by applying a dot matrix to both sides would enhance illumination significantly. Also by using the system, maintenance is reduced as well as the power requirements.
- the light source is generally fixed to only one edge of the transparent sheet. Only in very large signs may another light source be required on another edge.
- the density of dots preferably increases along the transparent sheet in the direction from the edge where the light source is to be fixed.
- the dots can either increase in number and the gaps between the dots decreases in size or alternatively, the gaps between the dots stay the same and the size of the dots increases.
- Dots used in the specification and in the claims can be of any shape, for example square, round, rectangular, triangular and in fact can be of irregular shape.
- the dots are translucent or opaque and more preferably light-coloured for example, white.
- the dots can be applied to the transparent sheet by etching, painting, screen printing or any other means of applying a medium to a transparent sheet.
- the matrix of dots may be applied to a transparent film which then may be adhered to the transparent sheet.
- the transparent sheet may be glass or plastic but is preferably acrylic.
- a backing plate is provided which is generally opaque and light in colour, preferably white.
- another sheet with a light coloured face, preferably white, facing the dot matrix of the transparent sheet is attached.
- This other sheet may be plain or have the sign applied to the other side.
- This other sheet should be sufficiently translucent to allow some light to pass through and illuminate the sign.
- the other sheet may be made of any material including plastics and paper.
- the light source can be retained in a carrier which can also act as a support for the transparent sheet.
- the light source is a fluorescent tube or depending on the size of the display, a number of tubes.
- Figure 1 illustrates a preferred embodiment of an illuminated display system of the present invention.
- Figure 2a illustrates a preferred embodiment of a one-sided sign.
- Figure 2b illustrates a preferred embodiment of a two-sided sign.
- Item 10 illustrates a transparent sheet 10 with the matrix of dots 13 applied to the surface 11.
- a matrix of dots 13 is also applied to the other side 12.
- the transparent sheet 10 can be accommodated in a carrier 20 which also houses a light source (not shown). It should be noted that the light source can be affixed in alternate ways, providing the light source is substantially on the edge of the transparent sheet 10.
- FIG 2a illustrates an arrangement for a one-sided sign in accordance with the invention.
- a backing sheet 14 which is opaque and preferably white in colour is fixed to the transparent medium 10.
- Sheet 15 has the sign printed on its front side. The side in substantial contact with transparent sheet 10 is light in colour and generally white. Sheet 15 is sufficiently translucent to allow some light to pass through the sheet and illuminate the sign. Materials found to be sufficiently translucent include paper (for example posters) and plastic materials.
- Figure 2b illustrates an arrangement for a two-sided sign in accordance with the invention.
- sufficiently translucent sheets 16 are fixed to the transparent sheet 10 with dot matrix thereon. These sheets 16 may be plain or have the sign applied to the outer face of the sheet. The face contacting the transparent sheet 10, at least, is light coloured and preferably white. Similarly if the sheet 16 is plain, the sheet is preferably light coloured and more preferably white. In the case where sheets 16 are plain, further sheets 17 may be incorporated into the sign system, wherein the sheets 17 have the sign applied thereto. Once again sheets 17 are sufficiently translucent to allow some of the light to pass through and illuminate the sign. Similarly for the one-sided sign sheet 15 may be plain and an additional translucent sheet (not shown) can be fixed in front of the plain sheet 15.
- the carrier and light source housing 20 can also retain the translucent sign sheet.
- the dot matrix in the first instance is only applied to one side of the transparent medium.
- the dot matrix in this preferred embodiment is applied by screen printing white dots directly on to the transparent material, in this case perspex.
- the density of the dot matrix increases away from the light source.
- the dot matrix is applied to both sides of the transparent medium in the same way as for the one-sided application.
- test results clearly indicate a marked improvement of the illumination of the sign when the dot matrix is applied to both sides of the transparent medium. This is especially true in the middle of the sign wherein most of the message to be illuminated is placed. Furthermore the effectiveness of the dot matrix is still good even for larger sizes.
- the display system in accordance with the invention can be used in small and very large displays and advantageously providing good illumination without the large number of lights previously required. Manufacturing and maintenance of the signs is less time consuming and simpler.
