摘要： A grating assisted optical waveguide for use in free space optical detection is disclosed. High speed, high sensitivity, large field of view, and relaxed tolerance on alignment are enabled. The grating converts a free space incoming optical beam into guided mode. Converted optical signals propagate along the waveguide, and can be directed to an optical detector. As such, the optical intensity at the active area of the detector is increased significantly. A number of optical beam converter gratings for free space light collection can be used, including linear and ring structure gratings, chirped gratings, and multilayer gratings. Such a grating assisted optical waveguide can be used, for example, in a digital wireless multimedia system, where digital content is wirelessly transmitted from a source to a target destination, such as home-based video and audio entertainment systems.

摘要： Techniques that provide cost effective optical fiber communication links for HDCP transmission systems and the like are provided. A single fiber for bidirectional communication is enabled, without wavelength selective unit to achieve the HDCP transmission. One embodiment of the present invention has a forward channel using a light source (e.g., VCSEL at about 850 nm) in the GHz modulation level (e.g., 1 GHz or greater), and a corresponding photodetector. The backward channel has a light source (e.g., LED at 630 nm) in the MHz modulation level (e.g., 10 MHz or less), and a corresponding photodetector. One application is for realizing a home entertainment system (e.g., DVD player and high definition television) that employs an HDCP-enabled communication link to transmit copy restricted digital content.

摘要： The present invention discloses a liquid crystal display apparatus and an LED backlight module incorporated therein, and the LED backlight module includes a boosting circuit for receiving a direct current voltage, boosting the direct current voltage, and then outputting a step-up direct current voltage; an LED string, including a plurality of LEDs connected in series, for receiving the step-up direct current voltage from the boosting circuit; a constant current driver circuit for generating a signal used for controlling the boosting circuit; and a amplifying circuit for receiving the direct current voltage, amplifying the signal from the constant current driver circuit, and then outputting a magnified signal to the boosting circuit. According to the liquid crystal display apparatus and the LED backlight module incorporated therein of the present invention, the power consumption of the boosting circuit is reduced by adding the amplifying circuit for amplifying a driving voltage to the boosting circuit. Furthermore, the driving voltage input to the MOS transistor of the boosting circuit is amplified by the amplifying circuit, and thereby the value of the DCR value of the MOS transistor is reduced. As a result, the power consumption of the MOS transistor is reduced, and the temperature is lowered, so the lifespan of the MOS transistor is extended.
