摘要： A method for manufacturing a display panel comprising light emitting device including micro LEDs includes providing multiple donor wafers having a surface region and forming an epitaxial material overlying the surface region. The epitaxial material includes an n-type region, an active region comprising at least one light emitting layer overlying the n-type region, and a p-type region overlying the active layer region. The multiple donor wafers are configured to emit different color emissions. The epitaxial material on the multiple donor wafers is patterned to form a plurality of dice, characterized by a first pitch between a pair of dice less than a design width. At least some of the dice are selectively transferred from the multiple donor wafers to a common carrier wafer such that the carrier wafer is configured with different color emitting LEDs. The different color LEDs could comprise red-green-blue LEDs to form a RGB display panel.

摘要： The present disclosure provides an apparatus for generating fiber delivered laser-induced white light. The apparatus includes a package case enclosing a board member with an electrical connector through a cover member and a laser module configured to the board member inside the package case. The laser module comprises a support member, at least one laser diode device configured to emit a laser light of a first wavelength, a set of optics to guide the laser light towards an output port. Additionally, the apparatus includes a fiber assembly configured to receive the laser light from the output port for further delivering to a light head member disposed in a remote destination. A phosphor material disposed in the light head member receives the laser light exited from the fiber assembly to induce a phosphor emission of a second wavelength for producing a white light emission substantially reflected therefrom for various applications.

摘要： A light source system or apparatus configured with an infrared illumination source includes a gallium and nitrogen containing laser diode based white light source. The light source system includes a first pathway configured to direct directional electromagnetic radiation from the gallium and nitrogen containing laser diode to a first wavelength converter and to output a white light emission. In some embodiments infrared emitting laser diodes are included to generate the infrared illumination. In some embodiments infrared emitting wavelength converter members are included to generate the infrared illumination. In some embodiments a second wavelength converter is optically excited by a UV or blue emitting gallium and nitrogen containing laser diode, a laser diode operating in the long wavelength visible spectrum such as a green laser diode or a red laser diode, by a near infrared emitting laser diode, by the white light emission produced by the first wavelength converter, or by some combination thereof. A beam shaper may be configured to direct the white light emission and an infrared emission for illuminating a target of interest and transmitting a data signal. In some configurations, sensors and feedback loops are included.
