| 20080278670 | Liquid crystal display device and method for manufacturing the same - The present invention provides a liquid crystal display device, by which it is possible to improve color reproducibility and contrast by adequately setting a value of Δn·d of each color without changing thickness of liquid crystal layer. A partition wall PT made of resin is prepared between pixels, which comprises color filter columns of CF-R, CF-G and CF-B. Within each of the pixels partitioned by the partition wall, liquid crystals LC(R), LC(G), and LC(B) having different values of Δn are filled In the pixels partitioned by the partition wall. The partition wall PT also fulfills the function as a spacer to maintain cell gap at a predetermined value. | 11-13-2008 |
| 20090059121 | Illumination Unit and Display Unit Incorporating the Same - An illumination device has at least one fluorescent tube, a lower frame supporting the fluorescent tube, a light diffusion plate which opposes the lower frame with the fluorescent tube being interposed therebetween for forward diffusion of output light of the fluorescent tube, a reflection sheet disposed along the fluorescent tube side of the lower frame for reflecting the fluorescent light toward the light diffuser plate, and an upside reflector covering an electrode of the fluorescent tube for reflecting the light toward the light diffuser. When letting a direction along a length of the fluorescent tube be a horizontal direction, a distance between the fluorescent tube and the reflection sheet at at least one of nearby portions of right and left ends of the illuminator is greater than such distance at a central portion thereof. A liquid crystal display (LCD) apparatus using the illuminator is also disclosed. | 03-05-2009 |
| 20090066874 | LIQUID CRYSTAL DISPLAY APPARATUS - In a liquid crystal apparatus in which a white light of a fluorescent tube corresponding to a linear light source repeats plural times of diffusions and reflections between a reflection sheet and a diffusion plate, and is thereafter input as a back light to a liquid crystal panel corresponding to a display screen, an object of the invention is to make it possible to secure a brightness uniformity even if the liquid crystal apparatus is thinned. It is possible to prevent a brightness unevenness caused by a short distance from the reflection sheet to the diffusion plate, by preventing a deformation (a deformation which is convex toward the fluorescent tube) of the diffusion plate due to a thermal expansion of the diffusion plate caused by a heat generation of the fluorescent tube, by arranging at least one pin mold hold so as to support a portion near an approximately center of the diffusion plate. | 03-12-2009 |
| 20090096951 | Liquid Crystal Display Device - An object is to provide a liquid crystal display device having a thin structure with a backlight device appropriate for illuminating a liquid crystal panel where there is no area in band form where the brightness is inconsistent. | 04-16-2009 |
| 20090096955 | Liquid Crystal Display Appliance and Lighting System - The present invention provides a liquid crystal display appliance in which portions of a liquid crystal display panel over luminescent lamps are not seen extraordinarily brighter and brightness of the liquid crystal display panel does not lower significantly at portions in the vicinity of the vertical direction edge of the liquid crystal display panel if a lighting system becomes thinner than 20 mm. This liquid crystal display appliance comprises a lighting system, in which a distance D between light reflector sheet | 04-16-2009 |
| 20090147175 | Liquid Crystal Display Appliance - A liquid crystal display apparatus which exhausts heat generated within the apparatus efficiently, and reduces temperature increase in the heat-frail sections is provided. | 06-11-2009 |
| 20100066943 | BACK LIGHT DEVICE, LIQUID CRYSTAL DISPLAY APPARATUS AND IMAGE DISPLAY APPARATUS USING THE SAME - The liquid crystal display apparatus includes a liquid crystal panel and the back light device for emitting the light from a light source to the liquid crystal panel through a lens. The light source includes a first LED for emitting the light of a first color, a second LED for emitting the light of a second color, a third LED for emitting the light of a third color, a fourth LED for emitting the light of the third color, a fifth LED for emitting the light of the second color, and a sixth LED for emitting the light of the first color. The first, second, third, fourth, fifth and sixth LEDs are arranged on the wiring board in such a manner as to offset the deviation of the light distribution. | 03-18-2010 |
| 20100271456 | CONFERENCE DETAILS RECORDING SYSTEM - The invention provides a conference details recording system for recording various types of information presented during the course of a conference by associating the contents of the presentation with speakers and with words, phrases, etc. in the presentation together with time information so that any type of information as desired can be retrieved later by using a predetermined retrieval key. The system comprises a conference room | 10-28-2010 |
