본 발명은 액정표시장치의 백라이트 유니트의 인쇄전용 시트구조에 관한 것으로서, 보다 상세하게는 백라이트유니트상의 광학불량을 개선시킬 수 있는 액정표시장치의 백라이트 유니트의 인쇄전용 시트구조에 관한 것이다.The present invention relates to a sheet structure for printing of a backlight unit of a liquid crystal display device, and more particularly, to a sheet structure for printing of a backlight unit of a liquid crystal display device that can improve optical defects on a backlight unit.

종래기술에 따른 액정표시장치의 백라이트 유니트의 인쇄전용 시트구조에 대해 도 1 및 도 2를 참조하여 설명하면 다음과 같다.The sheet structure for printing of the backlight unit of the liquid crystal display according to the prior art will be described with reference to FIGS. 1 and 2 as follows.

도 1은 종래기술에 따른 백라이트 유니트의 인쇄 시트구조를 설명하기 위한 백라이트유니트의 분리사시도 및 인쇄시트 결합사시도이다.1 is an exploded perspective view of a backlight unit for explaining a printing sheet structure of a backlight unit according to the related art and a perspective view of a printing sheet combined perspective view.

도 2는 종래기술에 따른 액정표시장치의 백라이트 유니트에 있어서 나타나는 문제점에 대해 설명하기 위한 인쇄전용 시트구조의 확대도이다.FIG. 2 is an enlarged view of a sheet structure for printing only for explaining a problem in the backlight unit of the liquid crystal display according to the prior art.

종래기술에 따른 액정표시장치의 백라이트 유니트의 인쇄 시트구조는, 도 1에 도시된 바와같이, 형광램프(미도시)와 형광램프(미도시)주위에 램프반사체(미도시)가 설치되며, 도광판(5)의 상면에는 몰드프레임(1)에 적층된 확산시트(7)와 프리즘시트(9)(11) 및 보호시트(13)가 배치되어 있으며, 상기 도광판(5)의 하단에는 반사판(3)이 배치되어 있는 구조로 되어 있다.In the printing sheet structure of the backlight unit of the liquid crystal display according to the prior art, as shown in Figure 1, a fluorescent lamp (not shown) and a lamp reflector (not shown) is installed around the fluorescent lamp (not shown), the light guide plate A diffusion sheet 7, a prism sheet 9, 11, and a protective sheet 13 stacked on the mold frame 1 are disposed on the upper surface of the mold frame 1, and a reflecting plate 3 is disposed on the lower end of the light guide plate 5. ) Is arranged.

또한, 상기 확산시트(7)에는 빛샘 개선을 위한 전면에 인쇄부(7a)가 형성되어 있고, 상기 보호시트(13)에는 휘선을 개선하기 위해 가장자리부에 인쇄부(13a)가 형성되어 있다. 즉, 입사광면에서의 휘선, ??샘의 경우에는 확산시트의 전면에 인쇄를 추가하고, 좌우측에서의 휘선, 빛샘의 경우에는 보호시트의 가장자리부에 인쇄를 추가한다. In addition, the diffusion sheet 7 has a printing portion 7a formed on the front surface for improving light leakage, and the protective sheet 13 has a printing portion 13a formed at an edge portion to improve bright lines. In other words, printing is added to the entire surface of the diffusion sheet in the case of the bright line and the light leakage on the incident light surface, and printing is added to the edge of the protective sheet in the case of the bright line and the light leakage on the left and right sides.                         

여기서, 도 2에 도시된 바와같이, 휘선(A)은 입광부에서 광 가이드의 빛이 반사판(reflect sheet)(3)에서 반사되어 강렬하게 보이는 현상을 말하며, 빛샘(B)은 광가이드의 빛이 반사판(3)과 램프반사체(미도시)사이로 새어 나오는 현상을 말한다. Here, as shown in FIG. 2, the bright line A refers to a phenomenon in which the light of the light guide is reflected by the reflector sheet 3 at the light-receiving part and appears to be intense, and the light source B is the light of the light guide. The phenomenon which leaks between this reflecting plate 3 and a lamp reflector (not shown) is said.

그러나, 상기와 같은 종래기술에 의하면, 시트에 인쇄작업을 할 경우 품질불량률이 10% 정도 상승하게 된다.However, according to the prior art as described above, the quality defect rate is increased by about 10% when printing the sheet.

또한, 인쇄로 인한 시트의 물성변화로 인하여 단품 자체의 신뢰성, 즉 온습도시험,이 떨어진다.In addition, due to the change in the physical properties of the sheet due to printing, the reliability of the unit itself, that is, the temperature and humidity test, falls.

그리고, 인쇄불량으로 인한 불량발생으로 인하여 시트 교체작업시에 2개의 시트를 검사, 교체하여야 하므로 추가 불량 발생의 여지가 있다.In addition, there is room for additional defects because two sheets must be inspected and replaced during sheet replacement work due to a defective printing.

더욱이, 시트 자체가 고가로써 위와 같은 불량으로 인하여 백라이트 유니트의 가격 상승의 원인이 된다.In addition, the sheet itself is expensive, which causes the price of the backlight unit to rise due to such defects.

이에 본 발명은 상기 종래기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 별도의 인쇄전용시트를 사용하여 인쇄작업을 단순화하므로써 인쇄로 인한 불량률을 감소시킬 수 있는 액정표시장치의 백라이트 유니트의 인쇄전용 시트구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art, the printing-only sheet of the backlight unit of the liquid crystal display device that can reduce the defect rate due to printing by simplifying the printing operation using a separate printing-only sheet The purpose is to provide a structure.

상기 목적을 달성하기 위한 본 발명에 따른 액정표시장치의 백라이트 인쇄전용 시트 구조는, 형광램프와 형광램프주위에 설치되는 램프반사체와, 도광판의 상 면에 배치되고 몰드프레임에 적층되는 확산시트와 프리즘시트 및 보호시트 및, 상기 도광판의 하단에 배치되는 반사판을 포함하여 구성되는 액정표시장치의 백라이트 유니트에 있어서, 상기 도광판과 확산시트사이에 인쇄전용 시트가 배치 되어 있는 것을 특징으로한다.In order to achieve the above object, a sheet structure for backlight printing of a liquid crystal display device according to the present invention includes a fluorescent lamp and a lamp reflector provided around the fluorescent lamp, a diffusion sheet and a prism disposed on the upper surface of the light guide plate and laminated on a mold frame. A backlight unit of a liquid crystal display device comprising a sheet, a protective sheet, and a reflecting plate disposed at a lower end of the light guide plate, wherein a sheet for printing is disposed between the light guide plate and the diffusion sheet.
