Abstract: A light-emitting device, including a first type semiconductor layer, a patterned insulating layer, a light-emitting layer, and a second type semiconductor layer, is provided. The patterned insulating layer covers the first type semiconductor layer and has a plurality of insulating openings. The insulating openings are separated from each other. The light-emitting layer is located in the plurality of insulating openings and covers a portion of the first type semiconductor layer. The second type semiconductor layer is located on the light-emitting layer.

Abstract: This invention is a new LED back lighting architecture that each individual LED is controlled by its associated LED drive cell. The LEDs are sequentially connected one after another. A host controller transmits image displaying signals by signal scanning-flows. The current flow for controlling each LED's color lighting is by either binary current flow control or two-steps progressive current flow control.

Abstract: This invention is an architecture of Driver IC used by the LED light systems. Each Driver IC comprises at least one Drive Cell that connects to an individual LED. The LED data are transmitted via a sequential scanning method from Drive Cell to Drive Cell, and from Driver IC to Driver IC that are connected in a cascade manner.

Abstract: This invention is an LED lighting intensity control by subdivision of PWM intervals to resolve the wavelength and luminance shifting problems that are caused by increasing heat and junction temperatures.

Abstract: A serial I/O testing method is performed by a testing system for testing a memory device having a first pin, a second pin, and a third pin. The testing method includes a step of inputting a clock into the memory device through the first pin, followed by a step of inputting a serial address into the memory device through the second pin synchronized with the clock. The method further includes a step of inputting a command into the memory device and a step of, when the command is a read command, outputting from the third pin a serially-written data synchronized with the clock. When the command is a program command, the method includes inputting an initial data serially through the third pin synchronized with the clock, and programming the initial data into the memory device before outputting it on the third pin as programmed data from the memory device synchronized with the clock.

Abstract: A hinge device includes female and male connecting members with two mounting sections fastened to two components of an electronic device for relative rotational movement. A tubular sleeve section of the female connecting member is formed integrally with the mounting section and confines an accommodation space therein. A cylindrical section of the male connecting member is formed integrally with the mounting section and is insertable into and is frictionally rotatable in the accommodation space. A grease receiving channel portion is formed in an outer surrounding surface of the cylindrical section, and includes two opposing channels and an interconnecting groove communicating with the channels such that grease is distributed evenly therein for obtaining a good lubricating effect.
