摘要: An alternating current light-emitting device includes a substrate, an alternating current microdie light-emitting module, and a conductive structure. The alternating current microdie light-emitting module is formed on the substrate and has at least two microdies and a concave portion disposed between the two microdies. Each of the microdies has at least one active layer. The conductive structure electrically connects the microdies and thereby enables the active layers of the microdies to take turns to emit light during positive and negative half cycles of alternating current. The conductive structure is formed in the concave portion and covers an insulator. The present invention prevents undue open circuits but enhances yield.

摘要: A method for detecting transitions in an input signal having a DC component. The method includes the steps of generating a threshold signal from the input signal, comparing the input signal to the threshold signal to thereby generate an output signal, and adjusting the threshold signal in response to the output signal. In one preferred embodiment, the method is employed to retrieve data from an information storage device.
