| 20080299860 | METHOD OF FABRICATING SMART DISPLAY CARD HAVING LIQUID CRYSTAL DISPLAY UNIT - The present invention relates to a method of fabricating a smart display card having a liquid crystal display unit. A synthetic resin sheet is punched using a press machine, thus forming a frame. The frame is attached to a transparent synthetic resin base sheet on which a gluing agent is coated. A liquid crystal display unit, an IC chip, a PCB, a CPU, and a thin film battery are attached to the transparent synthetic resin base sheet inside the frame. UV resin is coated inside the frame. A cover sheet is attached to the top surface of the frame. The cover sheet is flattenedly pressed in order to remove bubbles in the UV resin. The base sheet, the frame and the cover sheet are placed on a glass plate and then irradiated with UV in order to cure the UV resin. The base sheet and the cover sheet are separated from the frame. Synthetic resin printed sheets are adhered to the top surface and the underside of the frame using the cured UV resin, thus completing the smart display card. | 12-04-2008 |

| 20110013013 | WAFER INSPECTION APPARATUS - A wafer inspection apparatus that performs surface inspection and internal inspection of solar cells using a single apparatus. The wafer inspection apparatus includes a loading unit configured to allow a cassette to be lifted up or lowered by an elevator. A surface inspection unit includes a plurality of stages, thus performing surface inspection of each wafer using a first vision module. A wafer transfer unit has a rotatably installed center portion and has both ends provided with adsorption parts. An internal inspection unit is configured such that a conveyor is installed to allow the wafer to be transferred, thus performing internal inspection of the transferred wafer through a second vision module. An unloading unit enables wafers having completed the internal inspection to be sequentially loaded onto the unloading unit. A control unit controls a series of wafer inspection procedures. | 01-20-2011 |
