发明名称 CLUSTER LAMP AND LARGE-SIZED VIDEO DISPLAY DEVICE USING THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a large-sized video display device to which display signals of R,G,B can be transmitted on the radio and in which a two-dimensional display surface having an optional size can be constructed. SOLUTION: In a straight line type display device 29, N×Z pieces of cluster lamps 16 are provided successively in series and a controller 36 which performs the dispatching of a video signal and the supplying of power source is arranged at the low end part of the display device 29. The power source is supplied to the display device through power source receipt terminal 24 and the mounting screw 25 of each cluster lamp 16 with a cathode (ground) which serves both as an anode bar 37 and a support 38. A video signal 40 which is sent out from the controller 36 is successively transmitted from the cluster lamp 16 of the lowest stage to the cluster lamp 16 of the highest stage through light receiving part 26 and the light emitting part 27 of each cluster lamp 16. Each cluster lamp 16 extracts a signal having self-cluster lamp ID (identification)and makes light emitting elements 19 emit light based on the signal. COPYRIGHT: (C)2004,JPO
