  • Alpha-numeric display array and method of manufacture
    Patent number: 4345308
    Abstract: An alpha-numeric array is provided for the selective display of characters as controlled by associated character generator programming circuitry. The display array in one character format utilizes a 5.times.7 matrix array of individually operable illumination sources, LED solid state lamps for example, with programmed combinations of the individual illumination sources being operated to display the programmed characters. The display array includes a lens and front panel array having integrally formed lens areas. The lens areas of the lens and front panel array when unactuated are essentially indistinguishable from the front panel array background area thus providing improved contrast. The display array also includes a reflector array having integrally formed reflector cavities. The integrally formed reflector cavities include predetermined surface characteristics for collimating the light rays emanating from the central axis of the reflector cavities.
    Type: Grant
