Abstract: A signal processing device and method for driving one or more light emitting diodes (“LEDs”) of a video screen, display panel, module or other component. The signal processing device and method can control one or more RGB LEDs and/or white LEDs to produce light with increased uniformity and brightness at a reduced cost and having reduced power consumption. The signal processing device and method can generate a matrix brightness value based on one or more input LED driving signals; generate a complementary brightness value based on the one or more input LED driving signals; generate an LED driving signal based on the matrix brightness value and complementary brightness value; and delaying the one or more input LED driving signals generate one or more delayed LED driving signals.

Abstract: A system and method for the automatic color/brightness adjustment of a video display screen, panel, module or other display component comprising light emitting diodes (“LEDs”). The system and method incorporate a reference LED and a light sensor on each module and use decay information sensed from each reference LED to determine the amount of decay experienced by the display LEDs in the modules. Each module will be adjusted to have one uniform color/brightness level based on the decay information sensed from each reference LED.

Abstract: An SMD LED that is designed for indoor use is equipped for outdoor use by encapsulation in a vacuum-forming and/or cover molding covering, which is placed over the indoor SMD LED and is formed thereon by evacuation. The thus-equipped indoor SMD LED is thereby usable in the same manner as a more expensive and ruggedly designed outdoor SMD LED.

Abstract: An LED video display includes an array of LED elements mounted on an LED panel. A light baffle has openings to accept the LED elements, and reflectors are formed about each LED opening. A shader or rib is provided above each LED reflector in the light baffle. A second rib is provided below each LED reflector to form a rib pair between adjacent LED reflectors. Mounting openings in the light baffle are in place of the rib pair that would otherwise be present in the arrangement of ribs. A mounting clip having a rib pair is fastened to the LED panel. The rib pairs of the mounting clips are inserted through the mounting openings in the light baffle to secure the light baffle and LED panel to one another. The rib pairs of the clips align with the rib pairs of the light baffle.

Abstract: A three-dimensional television display including an LED screen having an array of light sources where the resolution of glass-less three-dimensional television display may be improved through the use of multiple LED array parallax, selection of the disposition of LED arrays in the multiple LED array parallax, a diagonal parallax barrier and lenticular lenses.

Abstract: A variable space shutter includes: a first frame having vertically spaced slats forming vertical openings; a second frame having a horizontal indented channel, the second frame being affixed to the first frame around a periphery of the first frame; and a shutter part having vertically spaced slats forming vertical openings, the shutter part being sandwiched between the first and second frames such that a portion of the shutter part rests within the horizontal indented channel to permit selective sliding movement of the shutter within the channel between a first position, wherein the vertical openings of the first frame line up with the vertical openings of the shutter part, to permit light to pass through the variable space shutter, and a second position, wherein the vertical openings of the first frame line up with the vertical slats of the shutter part, to block light from passing through the variable space shutter.
