Abstract
A display is disclosed. The display comprises a plurality of expandable tubes and a rollable material coupled to the expandable tubes, wherein the plurality of tubes can be expanded and contracted to increase or decrease the size of the display. The user of the expandable display in accordance with the present invention would have the benefit of having a much larger display to work with, and still be able to shrink it for ease of transportation. An added benefit to the user is that the color intensity of such a design is significantly higher than that of current LCD displays. Such displays also have the benefit of not requiring backlighting to operate.
Claims16
A display comprising:
- a plurality of expandable tubes;
- and
- a rollable material coupled to at least a portion of the plurality of expandable tubes, wherein the plurality of tubes can be expanded and contracted to increase or decrease the size of the display.
A display comprising:
- two expandable vertical tubes and two expandable horizontal tubes wherein the two vertical tubes allow the display to increase/decrease in size in the horizontal direction and the two horizontal tubes allow the display to increase/decrease in size in the vertical direction;
- wherein the two expandable vertical tubes and two expandable horizontal tubes operate independently to allow for increase/decrease in size of the display;
- wherein each of the two plurality of expandable vertical tubes comprises a central tube structure, telescoping rods within the central tube structure for the expansion and contraction of the expandable tube, wherein the two rods are offset from each other to avoid friction of the rollable material;
- wherein there are a plurality of sensors on the central tube structure to sense the increments of expandability;
- and
- a rollable material coupled to at least a portion of the plurality of expandable tubes, wherein the plurality of tubes can be expanded and contracted to increase or decrease the size of the display, wherein rollable material is affixed to each of the telescoping rods such that when the size of the display is enlarged, a first layer of the rollable material on one of the two rods travels upwardly with the edge of the display and a second layer of the rollable material on the other of the two rods remains stationary.
