11735 results about "LED display" patented technology

A LED display is a flat panel display that uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors where they are visible in the sun for store signs and billboards. In recent years, they have also become commonly used in destination signs on public transport vehicles, as well as variable-message signs on highways. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes.

Large Screen Portable LED Display

A large size display is transportable, being construed of multiple rigid segments containing light emitting diodes (LED's). The rigid segments are linked by hinges or cables so the display is flexible and can be rolled up for storage and transport. The display can be unrolled upward or downwards such as from a protective container, such as a canister or truss. The weight of the display on the linked hinges or the tensioned cables provides sufficient rigidity. Such cables, like a signal and power distribution bus, are connected to the rear of each rigid element. The display can be repaired by removing and replacing selected rigid segments from the front thereof.

Patterned inorganic LED device

A method of making an inorganic light-emitting diode display having a plurality of light-emitting elements including providing a substrate, and forming a plurality of patterned electrodes over the substrate. A raised area is formed around each patterned electrode to provide a well before depositing a dispersion containing inorganic, light-emissive core / shell nano-particles into each well. The dispersion is dried to form a light-emitting layer including the inorganic, light-emissive core / shell nano-particles. An unpatterned, common electrode is formed over the light-emitting layer. The light-emitting layer emits light by the recombination of holes and electrons supplied by the electrodes.

LED surface-mount device and LED display incorporating such device

In one embodiment, a surface-mount device comprises a casing having opposed, first and second main surfaces, side surfaces, and end surfaces. A lead frame partially encased by the casing comprises (1) an electrically conductive LED chip carrier part having a surface carrying a linear array of three LEDs adapted to be energized to produce in combination a substantially full range of colors, each LED having a first electrical terminal and a second electrical terminal, the first terminal of each of the three LEDs being electrically and thermally coupled to the chip carrying surface of the chip carrier part; and (2) three electrically conductive connection parts separate from the chip carrier part, each of the three connection parts having a connection pad, the second terminal of each of the three LEDs being electrically coupled to the connection pad of a corresponding one of the three connection parts with a single wire bond. The linear array of LEDs extends in a first direction, and each of the chip carrier part and three connection parts has a lead. The leads are disposed in parallel relationship with each other and extend through the end surfaces of the casing in a second direction, the second direction being orthogonal to the first direction. An array of the surface-mount devices may be used in an LED display such as an indoor LED screen.
