Dual-phase hybrid converter
A dual-phase hybrid DC-DC converter using a switched-capacitor technique is described. The dual-phase hybrid converter can reduce the volt-seconds on the inductors of the converter, which can allow for a reduction in the size of the inductors. In addition, the dual-phase hybrid converter can utilize inductors as current sources to charge and discharge the flying capacitors, which can reduce the size of the mid capacitor and increase solution density. Because charging and discharging are performed by inductors, the dual-phase hybrid converter can eliminate the capacitor-to-capacitor charge transfer. As such, the dual-phase hybrid converter does not need high capacitance to achieve high efficiency operation, which can further increase solution density. |

Non-blocked phosphorescent OLEDs
An organic light emitting diode (OLED) architecture in which efficient operation is achieved without requiring a blocking layer by locating the recombination zone close to the hole transport side of the emissive layer. Aryl-based hosts and Ir-based dopants with suitable concentrations result in an efficient phosphorescent OLED structure. Previously, blocking layer utilization in phosphorescent OLED architectures was considered essential to avoid exciton and hole leakage from the emissive layer, and thus keep the recombination zone inside the emissive layer to provide high device efficiency and a pure emission spectrum. |
