  • Publication number: 20100045898
    Abstract: A backlight unit for an LCD device produces a more uniform brightness by reducing or preventing bright lines occurring at the location of each LED device. The backlight unit includes a plurality of light guide plates which are arranged to overlap with an incident portion of adjacent light guide plate to at least partially cover the LED array. Accordingly, the backlight unit can prevent the generation of bright lines and hot spots caused when the light guide plate does not cover the LED array. As a result, the LCD device may improve images of uniform brightness.

  • Patent number: 7097967
    Abstract: The present invention provides a method of predicting a food-drug interaction in vivo, in the case of an orally administered drug interactive with digestive enzymes in the gastrointestinal tract, by measuring the activity of the drug to the digestive enzymes in vitro, which is based on the fact that the ingestion of foods causes the absorption of drug in vivo to decrease due to the above interaction between a drug and digestive enzymes. The present invention further provides methods of minimizing the change of absorption in vivo caused by the ingestion of foods by reducing the action of digestive enzymes, for example, introduction of prodrugs, modification of the chemical structure of drug, design of drug formulation, etc.
