Abstract
본 고안은 LCD장치용 도광판에 관한 것으로, 특히 백라이트 램프에서 조사되는 빛을 도광판의 전면부에 균일하게 분포시킬 수 있는 구형볼이 내장된 LCD장치용 도광판에 관한 것으로, 한쪽 측면에 백라이트 램프(10)가 설치된 도광관(16)의 내부에 복수의 구형볼(14)이 형성되고, 상기 복수의 구형볼(14)이 도광판(16)에 형성된 백라이트 홀(10)에서 멀어질수록 크기가 커지도록 구성하고, 또한 구형볼의 투명도를 조절하여 빛을 차단하고 공급하므로 빛을 균일하게 확산시킬 수 있는 효과가 있다.The present invention relates to a light guide plate for an LCD device, and more particularly, to a light guide plate for an LCD device having a spherical ball that uniformly distributes the light emitted from the backlight lamp to the front surface of the light guide plate. A plurality of spherical balls 14 are formed in the light guide tube 16 in which the plurality of spherical balls 14 is disposed, and the size increases as the plurality of spherical balls 14 move away from the backlight hole 10 formed in the light guide plate 16. It also has the effect of uniformly diffusing light because it blocks and supplies light by adjusting the transparency of the spherical ball.
Description
본 고안은 LCD장치용 도광판에 관한 것으로, 더욱 상세하게는 백라이트 램프에서 조사되는 빛을 도광판의 전면부에 균일하게 분포시킬 수 있는 구형볼이 내장된 LCD장치용 도광판에 관한 것이다.상기와 같이 구성된 종래의 도광판(2)은 도1 에 도시된 바와 같이 사각형상의 도광판(2)의 한쪽 측면에 백라이트 램프(8)가 설치되어 있다.The present invention relates to a light guide plate for an LCD device, and more particularly, to a light guide plate for an LCD device having a spherical ball that can evenly distribute the light emitted from the backlight lamp to the front surface of the light guide plate. As shown in FIG. 1, the conventional light guide plate 2 is provided with a backlight lamp 8 on one side of the rectangular light guide plate 2.
상기 종래와 같은 구성으로 도광판(2)에 흠집의 크기를 조절하여 왔기는 하지만 상기와 같이 흠집(6),(4)의 크기를 도광판(2)의 전면에 형성하여 조절하는 방식으로는 빛을 균일하게 확산시키지 못할 뿐만 아니라, 도1 에 표시된 A부분인 도광판(2)의 가장자리 부위가 백라이트 램프(8)와 가깝기 때문에 다른 부분에 비해 밝아 LCD화면의 색상이 혼탁해지는 문제점이 있었다.Although the size of the scratches on the light guide plate 2 has been adjusted in the same manner as in the related art, the size of the scratches 6 and 4 is formed on the front surface of the light guide plate 2 as described above. Not only do not diffuse uniformly, but because the edge portion of the light guide plate 2, which is the portion A shown in Figure 1 is close to the backlight lamp 8, there is a problem that the color of the LCD screen becomes cloudy compared to other parts.
도1 은 종래의 도광판 조를 나타내는 도면.1 is a view showing a conventional light guide plate group;
상술한 목적을 달성하기 위하여, 본 발명의 구형볼이 내장된 LCD장치용 도광판은 한쪽 측면에 백라이트 램프 홀이 형성된 도광판의 내부에 복수의 구형볼이 형성되고, 상기 투명 및 불투명한 복수의 구형볼이 도광판에 형성된 백라이트 홀에서 멀어질수록 크기가 커지도록 구성된 것이 특징이다.In order to achieve the above object, the light guide plate for a LCD device with a built-in spherical ball of the present invention is a plurality of spherical balls are formed in the light guide plate formed with a backlight lamp hole on one side, the plurality of transparent and opaque spherical balls It is characterized in that it is configured to increase in size away from the backlight hole formed in the light guide plate.
상기와 같은 본 발명의 구성으로 종래에 문제시되었던 도광판에서 조사되는 빛의 량을 구형볼의 크기와 투명도를 이용하여 빛을 조절하기 때문에 전면에 균일하게 확산시킬 수 있는 효과가 있다.With the configuration of the present invention as described above, the amount of light irradiated from the light guide plate, which has been a problem in the related art, is controlled by using the size and transparency of the spherical ball, so that the front surface can be uniformly spread.
