  • Patent number: 11925043
    Abstract: A quantum dot light-emitting device including first electrode and a second electrode, a quantum dot layer between the first electrode and the second electrode, a first electron transport layer and a second electron layer disposed between the quantum dot layer and the second electrode. The second electron transport layer is disposed between the quantum dot layer and the first electron transport layer, wherein each of the first electron transport layer and the second electron transport layer includes an inorganic material. A lowest unoccupied molecular orbital energy level of the second electron transport layer is shallower than a lowest unoccupied molecular orbital energy level of the first electron transport layer, and a lowest unoccupied molecular orbital energy level of the quantum dot layer is shallower than a lowest unoccupied molecular orbital energy level of the second electron transport layer. An electronic device including the quantum dot light-emitting device.

  • Patent number: 7177600
    Abstract: Disclosed are an apparatus and method for testing performance of a mobile station having a global positioning system (GPS) mounted therein. The method provides for virtually changing parameters requited for a registration at a base station so that the mobile station excludes the registration and directly enters a test state with an idle mode, and testing the performance of the mobile station in the idle mode test state. Accordingly, no re-boot is necessary to register with the base station upon completion of the test.
