摘要:
The present description is directed to a method for fabricating an electrophoretic display device that includes: forming a partition wall on a first substrate; filling a charged particle slurry in a three-dimensional space sectioned by a photo-curable or thermosetting resin layer and a sealant defining an edge on the resin layer; and combining the first substrate and the photo-curable or thermosetting resin layer together to have the partition wall immersed in the charged particle slurry, which fabrication method minimizes the defective proportion of final products and provides an electrophoretic display device with a high contrast ratio and enhanced visibility to implement high-quality text.
摘要:
The present invention relates to an electrophoretic display device that includes: first and second substrates separated from each other by a predetermined distance; first and second electrodes formed on one side of the first and second substrates, respectively, and disposed to face each other; a black pattern layer formed on the first electrode; a plurality of partition walls formed between the first and second electrodes, one side of the partition walls on the first electrode being in contact with or overlapped with the black pattern layer; and a slurry of charged white particles filled between the partition walls. The electrophoretic display device can exhibit a high contrast ratio and enhanced visibility to realize high-quality text.

摘要:
Provided are a human body communication apparatus for non-contact communications using a frequency-selective baseband and a human body communication method for non-contact communications in the same. The human body communication apparatus may be useful to perform stable communications between users by reducing interference induced from other communication apparatuses without affecting interference between the users since data are transmitted/received between communication apparatuses adjacent to a human body by spreading and despreading the data using only spreading codes of a limited frequency band (frequency-selective baseband) in which an inductive electromagnetic field formed by an antenna shows the most effective characteristics.
摘要:
A training apparatus based on motion content includes a plurality of motion detecting sensors (11 a . . . 11 n) dispersedly arranged in a body of a user to obtain position information signals of respective body parts of the user, a motion controller (20) analyzing the position information signals to detect a user motion, and comparing the detected motion with a reference motion provided from motion contents to generate a motion calibration signal for training of a motion calibration, and a plurality of motion calibrating sensors (12a . . . 12n) dispersedly arranged in the body to stimulate the body part of the user according to the motion calibration signal and calibrate the user motion, and consequently can provide a training service for continual motions and increase a motion calibration effect.

摘要:
There is provided a communications system and method using a part of human body as an antenna in a body area network, and more particularly, to a communications system and method enabling wireless communications using a low frequency band without the use of a bulky antenna in such a manner that a transmitting-side communications device applies electrical signals to a human body via a transmitting-side coupler to allow a part of human body to act as an antenna, and electrical signals, occurring in another part of human body due to radio frequency (RF) signals, are transferred to a receiving-side communications device via a receiving-side coupler.
