摘要:
An electrophoretic display and a method of manufacturing the electrophoretic display are provided. The electrophoretic display includes an lower electrode formed on an under layer, an lower electrode protection layer formed on the lower electrode, an insulating template formed on the lower electrode protection layer and having a plurality of holes of smaller size than the wavelength of visible rays region, a dielectric fluid filling the holes and having a color, a plurality of charged particles suspended in the dielectric fluid filling each of the plurality of holes having a color different from the color of the dielectric fluid, and an upper electrode formed on the insulating template in sequential order. Accordingly, a problem of agglomeration of the charged particles can be solved by the insulating template having holes of smaller size than the wavelength of visible rays region, and thus a reliable electrophoretic display emitting light of one color or natural colors is achieved.
摘要:
The present invention relates to printed circuit board (PCB) tracking technology, specifically to a dipole antenna structure for a radio frequency identification (RFID) tag. More specifically, the present invention relates to an edge type dipole antenna structure is implemented on an extremely small area on the edge of a ground plane provided on the PCB for various kinds of electronic products, and a PCB including the same.
摘要:
A wireless identification (RFID) tag, an electronic product PCB having same, and an electronic product management system using the RFID tag. The RFID tag includes an insulating means, a pair of upper terminals provided on the upper surface of the insulating means, a tag chip connected to the upper terminals, and a pair of lower terminals provided on the lower surface of the insulating means so as to face the upper terminals. The lower terminals are connected to first and second patterns of an electronic product PCB. When a radio wave radiated from a reader-writer is received in the first and second patterns, reactive coupling through an electric field is created between the upper and lower terminals, which are then electrically connected to the upper terminals. Since the pattern already formed in the PCB is used as an antenna, there is no need to form a dedicated antenna pattern.
