Description

곡면 백라이트유닛 및 이를 구비하는 디스플레이장치{curved back light unit and display device having the same}Curved back light unit and display device having the same {curved back light unit and display device having the same}

본 발명은 백라이트유닛 및 디스플레이장치에 관한 것으로, 더욱 상세하게는 광원으로부터 조사되는 광이 곡판형 광전도부재에 손실 없이 입사된 후 확산 및 굴절될 수 있도록 함으로써 광원으로부터의 광을 통해 곡판형 광전도부재를 균일하게 밝힐 수 있도록 하는 곡면 백라이트유닛 및 이를 구비하는 디스플레이장치에 관한 것이다.The present invention relates to a backlight unit and a display device, and more particularly, a curved photoconductor through light from a light source by allowing light emitted from a light source to be diffused and refracted after being incident to the curved photoconductive member without loss. The present invention relates to a curved backlight unit and a display device having the same to brighten the member evenly.

디스플레이장치의 디스플레이패널은 자체적으로 발광할 수 없다.The display panel of the display device cannot emit light by itself.

따라서, 디스플레이장치의 디스플레이패널 후방에는 광원 및 광전도부재를 구비하는 백라이트유닛이 마련되고 있다.Therefore, a backlight unit having a light source and a photoconductive member is provided at the rear of the display panel of the display device.

이와 같이 디스플레이패널 후방에 광원 및 광전도부재를 구비하는 백라이트유닛이 마련됨으로써 광원으로부터의 광이 광전도부재를 거쳐 상부로 출사된 후 디스플레이패널에 미치게 됨에 따라 디스플레이패널의 발광이 이루어질 수 있게 된다.As such, the backlight unit including the light source and the photoconductive member is provided at the rear of the display panel, so that light from the light source is emitted upward through the photoconductive member and then reaches the display panel.

한편, 일반 디스플레이장치의 백라이트유닛에는 도 7에 도시된 바와 같이 평판형 광전도부재(120')가 적용되는 것이 일반적이다.Meanwhile, as shown in FIG. 7, the flat panel photoconductive member 120 ′ is generally applied to the backlight unit of the general display apparatus.

그러나, 일부 디스플레이장치의 디스플레이패널은 곡면으로 제작되기도 하므로 공개특허 제10-2013-0020304호(공개일2013. 02. 27)에 개시된 바와 같은 곡판형 광전도부재가 적용되기도 한다.However, since the display panel of some display devices may be manufactured in a curved surface, a curved plate-shaped photoconductive member as disclosed in Korean Patent Laid-Open Publication No. 10-2013-0020304 (published Feb. 27, 2013) may be applied.

곡판형 광전도부재로부터의 광이 곡면 디스플레이패널에 미치게 되면 평판형 광전도부재로부터의 광이 평판형 디스플레이패널에 미치는 것에 비해 영상의 입체감이 더해질 수 있게 되므로 디스플레이 효과를 높일 수 있게 되고, 제품을 슬림화할 수 있게 된다.When the light from the curved photoconductive member reaches the curved display panel, the three-dimensional effect of the image may be added to the flat display panel with the light from the flat photoconductive member, thereby increasing the display effect. It becomes slim.

그러나, 백라이트유닛에서 일반적으로 설치된 광원(110')을 통해 곡판형 광전도부재(120") 하부에서 광을 조사하게 되면 디스플레이장치의 화질 저하로 이어지게 되는 문제가 있었다.However, when light is irradiated from below the curved photoconductive member 120 ″ through the light source 110 ′ generally installed in the backlight unit, there is a problem that leads to deterioration of image quality of the display apparatus.

즉, 일반적으로 설치된 광원(110') 통해 곡판형 광전도부재(120") 하부에서 광을 조사하게 되면 도 8에 도시된 바와 같이 비스듬히 입사하는 광의 일부는 부분 반사하여 반사광이 곡판형 광전도부재(120") 중심 측으로 유도되므로 곡판형 광전도부재(120")의 중심 외측으로 암부가 형성되어 결과적으로 디스플레이장치의 화질 저하로 이어지게 되는 문제가 있었다.That is, when the light is irradiated from the lower portion of the curved photoconductive member 120 ″ through the light source 110 ′ installed in general, as shown in FIG. Since it is guided to the center of the 120 ", a dark portion is formed outside the center of the curved photoconductive member 120", resulting in a deterioration in image quality of the display apparatus.

상기의 이유로 해당분야에서는 광원으로부터 조사되는 광을 통해 곡판형 광전도부재 각 부위를 균일하게 밝힐 수 있도록 하는 방안을 모색하고 있으나, 현재까지는 만족할만한 결과를 얻지 못하고 있는 실정이다.For the above reason, the related art seeks a method of uniformly illuminating each part of the curved photoconductive member through light emitted from a light source, but until now, satisfactory results have not been obtained.

본 발명은 상기와 같은 실정을 감안하여 제안된 것으로, 일반적인 광원 배치로는 곡판형 광전도부재의 각 부위를 균일하게 밝힐 수 없어 디스플레이장치의 화질 저하로 이어질 수밖에 없었던 문제를 해소할 수 있도록 하는 곡면 백라이트유닛 및 이를 구비하는 디스플레이장치를 제공하는데 그 목적이 있는 것이다.The present invention has been proposed in view of the above situation, and since a general light source arrangement can not illuminate each part of the curved photoconductive member uniformly, it is possible to solve the problem that could lead to deterioration of image quality of the display device. It is an object of the present invention to provide a backlight unit and a display device having the same.

한편, 곡판형 광전도부재(120)는 저면에 반사시트가 마련된 것이다.On the other hand, the curved photoconductive member 120 is provided with a reflective sheet on the bottom.

Since the reflective sheet is provided on the bottom surface of the curved photoconductive member 120, the light incident on the curved photoconductive member 120 may be reflected by the reflective sheet and emitted upward.

상기 바텀샤시(130)는 광원(110)이 안착되는 광원안착부(131) 및 광전도부재(120)가 안착되는 광전도부재안착부(132)가 마련된 것이다.The bottom chassis 130 is provided with a light source seat 131 on which the light source 110 is seated and a photoconductive member seat 132 on which the photoconductive member 120 is seated.

이와 같은 바텀샤시(130)에서 광원안착부(131)는 바텀샤시(130)의 양쪽 내측면을 따라 이어지는 것임이 바람직하다.In such a bottom chassis 130, the light source mounting part 131 may be extended along both inner surfaces of the bottom chassis 130.

It may be adjacent to both sides of the conductive member 120.

이때, 광원안착부(131)에 마련되는 기판(131a)은 곡판현 광전도부재(120) 측으로 기우는 것이 바람직하다.At this time, it is preferable that the substrate 131a provided on the light source seating portion 131 be tilted toward the curved plate photoconductive member 120.

광원안착부(131)에 마련되는 기판(131a)이 곡판형 광전도부재(120) 측으로 기움으로써 기판(131a)상에 배치된 각 광원(110)의 전면과 곡판형 광전도부재(120)의 측면이 평행하게 마주할 수 있게 되므로 광원(110)으로부터 조사되는 광이 비교적 손실 없이 곡판형 광전도부재(120)의 양 측면으로 입사될 수 있어 광원(110)으로부터의 광을 통해 곡판형 광전도부재(120)의 각 부위를 균일하게 밝힐 수 있게 된다.The substrate 131a provided on the light source seating portion 131 is tilted toward the curved photoconductive member 120, so that the front surface of each light source 110 disposed on the substrate 131a and the curved photoconductive member 120 are disposed. Since the side surfaces may be parallel to each other, light irradiated from the light source 110 may be incident on both sides of the curved photoconductive member 120 without relatively losing the curved photoconductivity through the light from the light source 110. Each part of the member 120 can be made uniform.

그리고 바텀샤시(130)의 광전도부재안착부(132)는 호형으로 되는 것이 바람직하다.In addition, the photoconductive member seating portion 132 of the bottom chassis 130 may be arc-shaped.

이때, 바텀샤시(130)의 광전도부재안착부(132) 상면에는 허니컴(honeycomb)부재(132a)가 마련되는 것이 바람직하다.In this case, it is preferable that a honeycomb member 132a is provided on the upper surface of the photoconductive member seating portion 132 of the bottom chassis 130.

The curved plate-shaped photoconductive member 120 can be stably supported through the unit 132, so that the curved plate-shaped photoconductive member 120 can continuously maintain the original curvature without deformation.

한편, 본 발명에 의한 디스플레이장치(도면상 미도시)의 특징은 상기에서 설명한 곡면 백라이트유닛(100)을 구비하는 것에 있으므로 디스플레이장치 자체에 관한 상세한 설명은 생략하는 바이다.
On the other hand, since the display device (not shown in the drawings) according to the present invention has the curved backlight unit 100 described above, a detailed description of the display device itself is omitted.

상기와 같은 곡면 백라이트유닛(100)에서 곡판형 광전도부재(120)를 통한 광 확산에 대하여 상세히 설명하면 다음과 같다.The light diffusion through the curved photoconductive member 120 in the curved backlight unit 100 as described above will be described in detail.

본 발명에서 바텀샤시(130)에는 광원(110) 및 곡판형 광전도부재(120)가 마련되어 있다.In the present invention, the bottom chassis 130 is provided with a light source 110 and a curved photoconductive member 120.

따라서, 광원(110)에 전원이 인가되면 광원(110)으로부터 광이 곡판형 광전도부재(120)에 미치게 되므로 곡판형 광전도부재(120)에서 상부로 광 출사가 이루어지게 된다.Therefore, when power is applied to the light source 110, light is emitted from the light source 110 to the curved photoconductive member 120, so that light is emitted upward from the curved photoconductive member 120.

이때, 광원(110)은 바텀샤시(130)의 내측면을 따라 이어지는 광원안착부(131)상의 기판(131a)에 배치되어 있는바, 광원안착부(131)상의 기판(131a)에 배치된 각각의 광원(110)은 곡판형 광전도부재(120) 양 측면에 인접하게 되므로 광원(110)으로부터 광이 곡판형 광전도부재(120) 양 측면을 통해 입사될 수 있어 곡판형 광전도부재(120)에서 상부로 광 출사가 이루어질 수 있게 된다.At this time, the light source 110 is disposed on the substrate 131a on the light source mounting portion 131 extending along the inner surface of the bottom chassis 130, and is disposed on the substrate 131a on the light source mounting portion 131. Since the light source 110 is adjacent to both sides of the curved photoconductive member 120, light from the light source 110 may be incident through both sides of the curved photoconductive member 120, and thus the curved photoconductive member 120 In this case, the light output can be made from above.

여기서, 광원안착부(131)상의 기판(131a)은 도 2에 도시된 바와 같이 곡판형 광전도부재(120) 측으로 기우는 것인바, 곡판형 광전도부재(120)의 양 측면에 인접하는 각 광원(110)의 전면은 곡판형 광전도부재(120)의 측면과 평행하게 마주하므로 광원(110)으로부터 광이 비교적 손실 없이 곡판형 광전도부재(120)의 양 측면으로 입사되므로 곡판형 광전도부재(120) 각 부위를 균일하게 밝힐 수 있게 된다.Here, the substrate 131a on the light source mounting part 131 is inclined toward the curved photoconductive member 120 as shown in FIG. 2, and the angles adjacent to both sides of the curved photoconductive member 120 are shown. Since the front surface of the light source 110 faces in parallel with the side of the curved photoconductive member 120, the light from the light source 110 is incident on both sides of the curved photoconductive member 120 with relatively no loss. Each part of the member 120 can be made uniform.

또한, 본 발명에서 곡판형 광전도부재(120)의 저면에는 도 6에 도시된 바와 같이 볼록형 돌기 또는 오목형 홈(121)이 전후좌우로 간격을 두고 연속되게 배치된 형태의 패턴이 형성되는바, 광원(110)으로부터의 광이 곡판형 광전도부재(120)로 입사되어 확산될 뿐만 아니라 볼록형 돌기 또는 오목형 홈(121)과 접하며 굴절될 수 있게 되므로 광의 확산 및 굴절에 의해 곡판형 광전도부재(120) 각 부위를 더욱 균일하게 밝힐 수 있게 된다.In addition, in the present invention, the bottom surface of the curved photoconductive member 120, as shown in Figure 6 is formed with a pattern of the convex protrusion or concave groove 121 is arranged continuously at intervals in front and rear, left and right In addition, since the light from the light source 110 is incident and diffused into the curved photoconductive member 120, the light may be refracted in contact with the convex protrusion or the concave groove 121. Each part of the member 120 can be more uniformly revealed.

한편, 곡판형 광전도부재(120)가 변형되거나 하여 애초의 곡률을 유지할 수 없게 되면 광원(110)으로부터 광 입사각이 애초 상태로부터 틀어질 수 있으므로 곡판형 광전도부재(120)에 광이 입사되는 과정에서 광 손실이 따를 수 있다.On the other hand, when the curved photoconductive member 120 is deformed to maintain the original curvature, the light incident angle from the light source 110 may be distorted from the original state, so that light is incident on the curved photoconductive member 120. Light loss may follow in the process.

그러나, 본 발명에서 곡판형 광전도부재(120)의 가장자리와 바텀샤시(130)의 내측면 사이에는 홀더(150)가 결합되는바, 홀더(150)에 의해 곡판형 광전도부재(120)가 바텀샤시(130)상에 견고히 고정될 수 있어 곡판형 광전도부재(120)의 변형이 방지될 수 있게 된다.However, in the present invention, the holder 150 is coupled between the edge of the curved photoconductive member 120 and the inner surface of the bottom chassis 130, and thus the curved photoconductive member 120 is formed by the holder 150. Since the bottom chassis 130 may be firmly fixed, deformation of the curved photoconductive member 120 may be prevented.

따라서, 곡판형 광전도부재(120)는 애초의 곡률을 지속적으로 유지할 수 있게 되므로 곡판형 광전도부재(120)에 광이 입사되는 과정에서 광 손실을 방지할 수 있게 된다.Therefore, since the curved photoconductive member 120 can maintain the curvature of the original, it is possible to prevent the light loss during the light incident on the curved photoconductive member 120.

더불어 본 발명에서 바텀샤시(130)의 광전도부재안착부(132) 상면에는 도 5에 도시된 바와 같이 허니컴부재(132a)가 마련되어 있는바, 허니컴부재(132a)의 구조적 특성에 의해 광전도부재안착부(132)가 견고해질 수 있게 되므로 광전도부재안착부(132)를 통해 곡판형 광전도부재(120)를 변형의 우려 없이 안정적으로 지지할 수 있게 된다.In addition, the honeycomb member 132a is provided on the upper surface of the photoconductive member seating portion 132 of the bottom chassis 130 as shown in FIG. 5, and the photoconductive member is formed by the structural characteristics of the honeycomb member 132a. Since the seating portion 132 may be firmly supported, the curved plate-shaped photoconductive member 120 may be stably supported by the photoconductive member seating portion 132 without fear of deformation.

따라서, 곡판형 광전도부재(120)는 애초의 곡률을 지속적으로 유지할 수 있게 되므로 곡판형 광전도부재(120)에 광이 입사되는 과정에서 광 손실을 방지할 수 있게 된다.Therefore, since the curved photoconductive member 120 can maintain the curvature of the original, it is possible to prevent the light loss during the light incident on the curved photoconductive member 120.

상기에서와 같이 본 발명에 의한 곡면 백라이트유닛(100) 및 이를 구비하는 디스플레이장치는, 바텀샤시(130)의 광전도부재안착부(132)가 호형으로 된 것이고, 호형으로 된 광전도부재안착부(132)에 곡판형 광전도부재(120)가 결합한 것이며, 곡판형 광전도부재(120) 양측 단부에 인접하는 광원(110)은 광원안착부(131)상의 기판(131a)이 곡판형 광전도부재(120) 측으로 기움에 따라 그 전면이 곡판형 광전도부재(120)의 측면과 평행하게 마주하는 것인바, 광원(110)으로부터의 광이 비교적 손실 없이 곡판형 광전도부재(120) 측면에 입사될 수 있게 되므로 광원(110)으로부터의 광을 통해 곡판형 광전도부재(120) 각 부위를 균일하게 밝힐 수 있게 되고, 곡판형 광전도부재(120)의 저면에 볼록형 돌기 또는 오목형 홈(121)이 전후좌우로 간격을 두고 연속되게 배치된 형태의 패턴이 형성된 것인바, 광원(110)으로부터의 광이 볼록형 돌기 또는 오목형 홈(121)과 접하며 굴절될 수 있게 되므로 광의 확산 및 굴절에 의해 곡판형 광전도부재(120) 각 부위를 균일하게 밝힐 수 있게 되며, 곡판형 광전도부재(120)가 홀더(150)에 의해 고정되는 것인바, 곡판형 광전도부재(150) 설치 이후 홀더(150)에 의해 곡판형 광전도부재의 변형이 방지될 수 있게 되고, 바텀샤시(130)의 광전도부재안착부(132) 상면에 허니컴부재(132a)가 마련된 것인바, 광전도부재안착부(132)를 통해 곡판형 광전도부재(120)를 안정적으로 지지할 수 있게 된다.As described above, in the curved backlight unit 100 and the display device having the same, the photoconductive member seating portion 132 of the bottom chassis 130 is arc-shaped, and the photoconductive member seating portion is arc-shaped. The curved plate-shaped photoconductive member 120 is coupled to the 132, and the light source 110 adjacent to both ends of the curved plate-shaped photoconductive member 120 has the substrate 131a on the light source seat 131 having the curved plate-shaped photoconductor. As the front surface of the member 120 is inclined to face the side of the curved photoconductive member 120 in parallel, the light from the light source 110 is relatively lost to the curved photoconductive member 120. Since it can be incident, each part of the curved photoconductive member 120 can be uniformly illuminated by the light from the light source 110, and a convex protrusion or a concave groove is formed on the bottom of the curved photoconductive member 120. 121) The tiles are arranged consecutively at intervals in front, rear, left and right. Since the light from the light source 110 can be refracted in contact with the convex protrusion or the concave groove 121, the respective portions of the curved photoconductive member 120 may be uniformly illuminated by the diffusion and refraction of the light. Since the curved photoconductive member 120 is fixed by the holder 150, deformation of the curved photoconductive member may be prevented by the holder 150 after the curved photoconductive member 150 is installed.
