20090179992 | DRIVING SYSTEM AND HAND TREMOR COMPENSATING APPARATUS ADOPTING THE SAME - A driving system is provided. The driving system includes a fixed substrate, a coil unit which generates an electromagnetic force if an electric current applied, a magnet unit formed on the fixed substrate to face the coil unit, and a plurality of driving units which are interconnected with each other on the fixed substrate, and which are moved respectively in parallel direction with respect to a surface of the fixed substrate in accordance with an interaction between the electromagnetic force and a magnetic force of the magnet unit, if the electric current is applied. As a result, a non-contact driving is provided. | 07-16-2009 |
20100201603 | MULTI-DISPLAY APPARATUS - Provided is a multi-display apparatus formed by connecting a plurality of display panels. The multi-display apparatus includes a first display panel, a second display panel disposed to overlap at least a portion of the first display panel, a transparent plate disposed only on the second display panel, or on both the first display panel and the second display panel, and a transparent window disposed on an area corresponding to the first display panel and the second display panel. The transparent window is foldable when the multi-display apparatus is folded. | 08-12-2010 |
20100201604 | MULTI-FOLDABLE MOBILE DISPLAY APPARATUS - A multi-foldable mobile display apparatus includes a first display panel, a second display panel, and a third display panel which are successively disposed in an unfolded state of the multi-foldable mobile display apparatus, and a transparent plate disposed on the second display panel. The second display panel is disposed on a same side of both the first display panel and the third display panel, so that opposing edges of the second display panel respectively overlap the first display panel and the third display panel, in a plan view of the multi-foldable mobile display apparatus. | 08-12-2010 |
20100321330 | TOUCH PANEL AND ELECTRONIC DEVICE INCLUDING THE SAME - A touch panel which is used as an input device for an electronic device, etc., and an electronic device including the touch panel are provided. A touch panel includes a first substrate, and a second substrate spaced from the first substrate by a distance and having a contact surface. A fluid is filled in a gap between the first substrate and the second substrate, and an input button area is delimited due to movement of the fluid when a driving voltage is applied. If a thickness of the gap between the first substrate and the second substrate is reduced below a threshold thickness value in the input button area, the driving voltage is cut off. | 12-23-2010 |
20100321335 | TOUCH PANEL AND ELECTRONIC DEVICE INCLUDING THE SAME - A touch panel and an electronic device are provided. The touch panel includes a first substrate; a second substrate that is spaced apart from the first substrate by a gap and includes a contact surface; driving electrodes that are formed on each of the first substrate and the second substrate; and electro-rheological fluid that is disposed in the gap. When a driving voltage is applied between the driving electrodes, a button area is delimited due to a variation in viscosity of the electro-rheological fluid at the button area. When a thickness of the gap is reduced to a value equal to or less than a threshold due to a pressing force applied to the contact surface at the button area, the driving voltage is cut off. | 12-23-2010 |
20140299231 | METAL-BASED SOLDER COMPOSITE INCLUDING CONDUCTIVE SELF-HEALING MATERIALS - A solder composite is provided. The solder composite may include: a metal-based solder matrix, a capsule dispersed in the solder matrix, and a self-healing material that is encapsulated in the capsule. The self-healing material may be configured to react with the solder matrix when in contact with the solder matrix such that at least one of an electrically conductive intermetallic compound and an electrically conductive alloy is formed. | 10-09-2014 |
