摘要： A dimming structure for an image display device further includes a contrast panel for altering contrast differences in a portion around an outputted image to achieve dimming effects on an image smaller than a light emitting lamp. In the dimming structure, a backlight unit has a plurality of light sources disposed therein. A display panel displays an image while the backlight unit is disposed to light the display panel. A contrast panel is disposed between the backlight unit and the display panel. The contrast panel has a light emitting window formed in a portion thereof corresponding to the image of the display panel to transmit light emitted from the backlight unit therethrough. The dimming structure assures uniform dimming effects on the portion around the image despite use of a light source bigger than the image to be outputted.

摘要： A backlight unit of the invention is reduced in thickness, weight and manufacturing costs but improved in heat releasing efficiency. In the backlight unit, a flexible printed circuit board has at least one through hole perforated therein. An LED package is disposed on a top portion of the flexible printed circuit board corresponding to the through hole. The backlight unit of the invention employs the flexible printed circuit board in place of a metal printed circuit board as a means to conduct current to the LED package. This produces a slimmer and lighter backlight unit and also saves manufacturing costs. In addition, the LED package is directly bonded onto a bottom plate by a heat conducting adhesive, thereby ensuring heat generated from the LED package to be released more quickly.
摘要翻译：本发明的背光单元的厚度，重量和制造成本降低，但散热效率提高。在背光单元中，柔性印刷电路板具有穿孔的至少一个通孔。 LED封装设置在与通孔对应的柔性印刷电路板的顶部上。本发明的背光单元采用柔性印刷电路板代替金属印刷电路板作为将电流传导到LED封装的手段。这产生了更薄和更轻的背光单元，并且还节省制造成本。此外，LED封装通过导热粘合剂直接接合到底板上，从而确保从LED封装产生的热量更快地释放。

摘要： A backlight unit for a liquid crystal device capable of obtaining a high-quality image and reduced in thinness. The backlight unit is disposed below a liquid crystal panel to irradiate light thereto. A plurality of separate light guide plates define respective blocks. Groups of LEDs each are disposed along an edge of each of the light guiding plates, each of the LED groups emitting light toward a corresponding one of the light guide plates. Each LED group is turned on and off according to the corresponding block.

摘要： In an LCD backlight unit using a light emitting diode, a double-sided printed circuit board includes a plurality of divided areas and conductive vias. A plurality of light emitting diodes are disposed on a top surface of the double-sided printed circuit board. A plurality of driving circuit connectors are disposed at a portion of the double-sided printed circuit board. A plurality of first lead patterns are formed on the top surface of the printed circuit board, each of the first lead patterns electrically connecting the light emitting diodes in each of the divided areas with one another. Also, a plurality of second lead patterns are formed on an underside surface of the double-sided printed circuit board to electrically connect the first lead patterns with the connectors through the conductive vias.
