A display drive apparatus for driving a display pixel including a light-emitting element and a drive element in which one end of a current path is connected to the light-emitting element. The switch element includes, a receiving segment in a fibre channel port for receiving the frames and a transmit segment that transmits the received frames. The actuator assembly is configured to lock when the second clutch dog to thereby inhibit automatic disengagement of the second clutch dog from the first clutch dog. In another aspect, a support structure includes an array of LED emitters. The method thereby enhances the performance of DRAM MIM capacitor. The central disk also has a radial legend representing distance to the target.
