    摘要： A master station includes an optical transmission interface for transmitting signals to a plurality of slave stations at a first transfer rate or a second transfer rate which is higher than the first one, packet buffers for accumulating the signals addressed to each of the plurality of slave stations, and a control unit for determining transmission timings and transfer rates of the signals on the basis of an amount of the signals accumulated in the packet buffers, transmitting the signals with the determined timings and rates, and notifying each of the slave stations about the determined timings and rates. Each of the slave stations includes an optical reception interface for receiving the signals of the first transfer rate or the second transfer rate, and a control unit for controlling the optical reception interface on the basis of the timings and rates which the slave stations is notified.

    摘要： A surface light source device having a local dimming function and an LCD unit using the device can include a light guide having a top surface including a plurality of linear convexes and a bottom surface including a plurality of dots. The device can also include a reflective sheet located adjacent the bottom surface, a prism sheet located adjacent the top surface, a diffusing sheet located adjacent the prism sheet, and a pair of LED light sources located adjacent both light incident surfaces of the light guide and divided into a plurality of groups. Each light emitted from the groups can be configured to be emitted independently from a respective one of local domains on a light-emitting surface of the device. Therefore, the disclosed subject matter can provide a surface light source device having a local dimming function with a simple structure as with a conventional edge light type device.
