    摘要： A microLED mass transfer stamping system includes a stamp substrate with an array of trap sites, each configured with a columnar-shaped recess to temporarily secure a keel extended from a bottom surface of a microLED. In the case of surface mount microLEDs, the keel is electrically nonconductive. In the case of vertical microLEDs, the keel is an electrically conductive second electrode. The stamping system also includes a fluidic assembly carrier substrate with an array of wells having a pitch separating adjacent wells that matches the pitch separating the stamp substrate trap sites. A display substrate includes an array of microLED pads with the same pitch as the trap sites. The stamp substrate top surface is pressed against the display substrate, with each trap site interfacing a corresponding microLED site, and the microLEDs are transferred. Fluidic assembly stamp substrates are also presented for use with microLEDs having keels or axial leads.

    摘要： A light emitting device is provided for increasing light emission efficiency, and a vehicle lamp or lighting apparatus including the same. The light emitting device includes a light emitter, a light transmitter disposed on a first region corresponding to at least a portion of a top surface of the light emitter and configured to change a characteristic of light emitted from the light emitter, and a light extraction layer disposed on a top surface of the light transmitter. A refractive index of air corresponds to a first refractive index, a refractive index of the light transmitter corresponds to a second refractive index, and the light extraction layer has a third refractive index in a range between the first refractive index and the second refractive index.
