Reduction Of Defective Pixel Appearance In Light-Emitting Arrays

View page

US Patent:

20220181515, Jun 9, 2022

Filed:

Dec 1, 2021

Appl. No.:

17/539941

Inventors:

- San Jose VA, US
Hossein Lotfi - Folsom CA, US
Isaac Wildeson - San Jose CA, US
Oleg Shchekin - San Francisco CA, US

Assignee:

LUMILEDS LLC - San Jose CA

International Classification:

H01L 33/02
H01L 33/50
H01L 33/08

Abstract:

An inventive light-emitting apparatus comprises an array of multiple light-emitting pixels, and one or more transmissive optical elements positioned at a light-emitting surface of the light-emitting pixel array. One or more of the light-emitting pixels is defective. Each optical element is positioned at a location of a corresponding defective light-emitting pixel, and extends over that defective pixel and laterally at least partly over one or more adjacent pixels. Each optical element transmits laterally at least a portion of light emitted by the adjacent pixels to propagate away from the array from the location of the defective pixel, reducing the appearance of the defective pixel.

US Patent:

20230126041, Apr 27, 2023

Filed:

Aug 30, 2022

Appl. No.:

17/898971

Inventors:

- San Jose CA, US
Hossein Lotfi - Folsom CA, US
Ronald Bonne - Plainfield IL, US
Toni Lopez - Vaals, NL

Assignee:

Lumileds LLC - San Jose CA

International Classification:

H01L 33/00
H01L 25/075
H01L 33/62

Abstract:

A light emitting diode (LED) device comprises a plurality of pixels on a backplane, each pixel comprising: semiconductor layers, which include an N-type layer, an active region, and a P-type layer; a cathode electrically contacting the N-type layer; an anode comprising anode segments electrically contacting respective portions of the P-type layer; one or more dielectric materials insulating: the active region and the P-type layer from the cathode, the anode segments from each other, and the anode segments from the cathode; and a plurality of interconnects, each respective interconnect affixing a respective anode segment to the backplane. Methods of making and use the devices are also provided.
