Abstract

A laminate artwork system includes a plurality of stacked, uniformly spaced light transmitting artwork panels, each having a portion of an overall artwork image etched thereon. The artwork panels are generally rectangular and have aligned edges positioned within a frame. The frame houses fluorescent lamps generally adjacent to and extending the length of the panel edges, and includes an inner reflective surface which directs substantially all of the emitted light towards the panel edges. Disposed between the lamp and the panel edges are a plurailty of color filters and shutters which control the transmission and intensity of light permitted to pass therethrough to the edges. The shutters comprise liquid crystal gates responsive to an input signal, which are modulated to allow a varied amount of light to pass through so that different levels of brightness and/or color of the artwork image may be obtained. A unique visual appearance is attained by illuminating the edge of the artwork panels such that the panels themselves act as conduits for the light to the artwork images. Depending on modulation of the liquid crystal gates, various colors and moving images may be obtained in the stacked panels.

Claims

1. An artwork system, comprising:

a light transmitting artwork panel having at least one edge and a viewing face generally perpendicular to the at least one edge;

an artwork image provided on the panel, the image being visible on the viewing face when the at least one edge is illuminated;

means for illuminating the at least one edge of the artwork panel;

means disposed between the at least one edge and the illuminating means, for controlling illumination of the at least one edge and transmission of light through the artwork panel, the controlling means including means for intercepting light emitted from the illuminating means, the light intercepting means including a plurality of liquid crystal gate shutters which overlie the at least one edge in a manner controlling the transmission and intensity of light permitted to pass therethrough to the at least one edge; and

means for modulating the shutters of the intercepting means in response to an input signal, comprising a control circuit including a bank of liquid crystal drivers, wherein each driver is electrically connected to a respective single liquid crystal gate to impress upon the gate an electrical signal by which the transparency, translucency or opacity of the liquid crystal gate is controlled in accordance with the input signal.

2. An artwork system as set forth in claim 1, wherein the artwork image is etched into the panel to capture light transmitted therethrough.

3. An artwork system as set forth in claim 1, wherein the artwork panel includes a plurality of stacked, generally parallel panels having aligned edges which provide the at least one edge.

4. An artwork system as set forth in claim 3, wherein the plurality of panels are generally transparent such that artwork images provided on underlying panels may be viewed through a top panel.

5. An artwork system as set forth in claim 4, wherein the illuminating means includes a fluorescent lamp positioned generally adjacent to and extending the length of the aligned edges.

6. An artwork system as set forth in claim 1, including means disposed between the at least one edge and the illuminating means, for color-filtering light emitted from the illuminating means.

7. An artwork system, comprising:

a plurality of stacked, generally parallel light transmitting artwork panels, each panel having a viewing face and an edge generally perpendicular to the viewing face;

an artwork image provided on each of the panels, the artwork image being visible on the viewing face by an observer facing a top one of the panels, when the respective edge is illuminated;

means for illuminating the edges of the stacked artwork panels;

means for color-filtering light emitted from the illuminating means;

a plurality of liquid crystal gate shutters disposed between the edge of each panel and the illuminating means, the shutters overlying the edges in a manner controlling the transmission and intensity of light permitted to pass therethrough to the edges; and

means for modulating the shutters in response to an input signal, including control circuit including a bank of liquid crystal drivers, wherein each driver is electrically connected to a respective single liquid crystal gate to impress upon the gate an electrical signal by which the transparency, translucency or opacity of the liquid crystal gate is controlled in accordance with the input signal.

8. An artwork systems as set forth in claim 7, including means for blocking light permitted to pass through one shutter to illuminate a selected portion of the edge of the first panel, form illuminating any portion of the edge of a second panel.

9. An artwork system as set forth in claim 7, wherein the light color-filtering means includes sequential red, green/yellow and blue color filters disposed adjacent to the shutters.

10. An artwork system as set forth in claim 7, wherein the artwork image is sculpted into each panel to capture light transmitted through the artwork panel.
