A visual display apparatus for generating an apparent visual message includes an annular drum which is rapidly rotated. Three columnar light banks are secured to drum face and each include a plurality of lights. A microprocessor and power unit is mounted to and rotates with the drums and activates the lights to generate a message or character on the drum which defines one message display frame. The microprocessor includes a program for each of the light banks for individually energizing the lights. The program includes a message program and a fixed program for processing of the message data. The message scrolls across the drum in the direction opposite the drum rotation, and the total message may consist of a plurality of frames. Each display frame covers less than the drum periphery and includes a start column and a spaced end column. A position sensor initiates the processor and generates a train of timing signals, one for each drum travel display column. During each revolution the processor sequences and operates the light banks with the alignment thereof with each display column. The light banks are spaced two message columns and the processor sequentially monitors the start column and end column of each frame to restrict activation of the light banks to those within the frame and therebetween enables all three banks to produce the desired color message presentation.
A surround-vision display system with a very high visual dynamic range is made possible by distributing a limited number of LED's on the inside of a drum and then spinning that drum around a user. The pixel information for each horizontal position in space is sent to each corresponding LED it visits that position. The LED's are arranged in a grid on a panel tile, and the panel tile is tilted slightly, e.g., at 1.1-degrees. The result is each panel tile presents a continuous vertical stripe in the picture frame as all its LED's are swept by in the drum motion. Several panel tiles stacked vertically inside the drum all contribute to the whole height of the picture frame, e.g., several feet. The entire inside circumference of the drum is populated with the LED panel tiles to keep frame refresh rates up to avoid flicker while keeping drum rotation speeds down to reasonable levels. Thus even though the LED's and drum are moving, the image projected appears to be relatively stationary.
A display apparatus includes a pedestal, a cylindrical display body rotatably mounted on the pedestal, a plurality of light emitting lines composed of a plurality of units, each line being equidistantly and axially arranged on a wall of the display body for displaying information when the display body rotates, a control circuit mounted on the display body for controlling a rotating speed of the display body and the information displayed on the display apparatus, and a power supply having a positive electrode and a negative electrode provided within the pedestal for providing the power required by the apparatus.
A display comprises a static unit (8) on which is mounted a rotating unit (7) driven by a motor (12). The rotating unit carries light emitting diodes (6) arranged as vertical columns which sweep around a cylindrical surface. The light emitting diodes (6) are controlled by a control circuit (6) in accordance with data stored in a memory (61) so as to provide a cylindrical display. The control circuit (60) and memory (61) are located in the rotating unit 97) and the memory (612) has a capacity for storing several different images for display.
A display apparatus combines a product display container and a plurality of light controlled light sources, wherein the light sources operate to create a visual image advertising the product.
A scrolling display system has a plurality of light emitting cell array segments, each being consisted of a given number of light emitting cells arranged in alignment with a given dot interval, the plurality of light emitting cell array segments being arranged in one of column and row directions in spaced apart relationship for forming a display plane, an interval of adjacent light emitting cell array segments being greater than the given dot interval, an image memory storing an image data to be displayed on the display plane, the image data containing pixel information for all pixels to form dot matrix on the display plane with the given dot interval in column and row directions, and a display controller reading out data fractions of the image data corresponding to respective of light emitting cell array segments and supplying the data fractions to respective light emitting cell array segments for driving light emitting cell array segments, the display controller controlling shifting of display image in the one of column and row directions for adjusting scroll speed depending upon the interval between adjacent light emitting cell array segments.
