  • Patent number: 11618673
    Abstract: A transfer system for transferring multiple microelements to a receiving substrate includes a main pick-up device, a testing device, and first and second carrier plates. The testing device includes a testing platform, a testing circuit, and multiple testing electrodes electrically connected to the testing circuit. The main pick-up device is operable to releasably pick up the microelements from the first carrier plate and position the microelements on the testing electrodes. The testing device is operable to test the microelements to distinguish unqualified ones of the microelements from qualified ones. The main pick-up device is operable to release the qualified ones of the microelements to the receiving substrate.

  • Patent number: 9312449
    Abstract: An electrode structure for effectively improving the stability of a semiconductor LED includes a reflecting layer capable of current spreading. In such an electrode structure, the current injects from the side surface of the reflecting layer to form a certain potential gradient over the contact surface between the electrode and the LED contact surface, thereby inhibiting the metal ion of the reflecting layer from migration due to electric field during usage, thereby improving device stability. In addition, the electrode portion for current injection can include a high-reflectivity material yet not vulnerable to ion migration, thereby increasing the entire reflecting area and improving luminous efficiency.
