  • Patent number: 11567359
    Abstract: A display panel and a display apparatus are provided. The display panel may include a first glass substrate; a second glass substrate provided in front of the first glass substrate in a first direction; and a color filter layer provided between the second glass substrate and the first glass substrate in the first direction. The color filter layer may include a plurality of color filters and a black matrix surrounding the plurality of color filters. A side edge of the black matrix may extend beyond a side edge of the first glass substrate in a second direction that is orthogonal to the first direction. The display apparatus may include a backlight unit and the display panel.

  • Patent number: 8021206
    Abstract: A fluorescent lamp that can be easily manufactured to provide high brightness and high efficiency, a method of manufacturing the same, and a backlight unit having the same are provided. First and second non-emissive glass tube are joined to an emissive glass tube coated with a phosphor, and first and second electrodes are formed on outer surfaces of the first and second non-emissive glass tubes. The first and second non-emissive tubes may have the same diameter as the emissive glass tube. The first and second non-emissive glass tubes are simply joined to the emissive glass tube, thereby reducing the manufacturing process and cost. The first and second non-emissive glass tubes are formed to be thinner than the emissive glass tube, thereby enhancing the brightness and efficiency of the fluorescent lamp.
