| 20080273147 | Liquid crystal display device having black/white LCD panel - Disclosed is a Liquid Crystal Display (LCD) device including a black/white LCD panel for displaying an image, a color filter disposed on a rear surface of the black/white LCD panel in order to filter input light into light of preset colors and output the filtered light to the black/white LCD panel, and a back light unit having a plurality of optical sheets to output white light to the color filter. The color filter is integrated with one of the plurality of optical sheets as one piece. | 11-06-2008 |
| 20100073583 | FLANGE STRUCTURE FOR A PORTABLE TERMINAL - Disclosed is a portable terminal including a case having an opening that faces towards a user operating the terminal and a flange protruding towards the opening, a lower window having a partial surface that is attached to a lower surface of the flange, an upper window attached to the lower window to be exposed through the opening, and a liquid crystal panel placed under the lower window. The stress concentrated on and the likelihood of breakage of the flange structure of the portable terminal in which the case is connected with the window is thereby minimized. | 03-25-2010 |
| 20100117995 | WHEEL DRIVER AND PORTABLE ELECTRONIC DEVICE HAVING THE SAME - A pattern wheel driver is provided. The pattern wheel driver includes a rotatable pattern wheel with patterned regions repeatedly formed on the pattern wheel. Each of the patterned regions has a plurality of patterns. Each of the plurality of patterns has a different width. The pattern wheel driver also includes a detector for detecting the plurality of patterns, mounted at a position where the patterned regions of the pattern wheel pass when the pattern wheel rotates. The pattern wheel driver also includes an encoder for producing a signal indicating whether the pattern wheel rotates in a forward direction or a reverse direction based on signals produced by the detector. | 05-13-2010 |
