  • Publication number: 20250204103
    Abstract: AlInGaP microLEDs comprise AlInGaP quantum dots disposed in one or more quantum wells in the microLED light emitting active region. The quantum dots trap and confine carriers (electrons and holes) that are injected into the light emitting active region during operation of the microLED, preventing the confined carriers from moving laterally along the quantum wells to reach nonradiative recombination centers at the perimeter surfaces of the device and thereby increasing the light emitting efficiency of the microLED.

  • Patent number: 7672897
    Abstract: In accordance with the present invention, a method and system of communal purchasing is disclosed. The preferred embodiments describe a community purchase model where a product can be purchased a particular price only if enough buyers are willing to purchase at that price. The preferred embodiments pool together the collective buys for a product to get a better price than if an individual buyer was to purchase the product by himself/herself. Therefore, a fixed “discount” price is used to collect a number of buys, wherein the number of buys is recorded in a specific product record and the transaction to purchase the product is consummated if the number of buys for the product reaches a minimum number of buys. Moreover, further embodiments obtain a pre-payment or a guarantee for payment for the product while collecting buys for the product.
