본 발명은 엘시디 모듈에 관한 것으로, 컬러필터 및 광원 기능을 갖는 발광소자를 엘시디 패널에 적용함으로써 엘시디 모듈의 두께가 줄어들고 종래에 컬러필터로 인해 저하되던 광효율이 향상되는 효과가 있다.The present invention relates to an LCD module, and by applying a light emitting device having a color filter and a light source function to an LCD panel, the thickness of the LCD module is reduced, and light efficiency, which has been degraded due to the color filter, is improved.
Description
본 발명은 엘시디 모듈에 관한 것으로, 더욱 상세하게는 칼라필터를 제거하여 광투과율을 향상시킬 수 있도록 엘시디 모듈에 관한 것이다.The present invention relates to an LCD module, and more particularly to an LCD module to remove the color filter to improve the light transmittance.
일반적으로 엘시디 모듈(LCD module)은 백라이트 어셈블리와 엘시디 패널과 엘시디 패널을 구동하는 구동회로부 등을 구비하여 이루어진다.In general, an LCD module includes a backlight assembly, an LCD panel, and a driving circuit unit for driving the LCD panel.
백라이트 어셈블리는 소비전력이 낮고 온도 특성이 좋으며 수명이 긴 것이 선호된다. 이를 위해 냉음극관이 일반적으로 사용되고, 패널 전면에 균일한 광을 전달하기 위해 도광판이 사용된다.The backlight assembly is preferred for low power consumption, good temperature characteristics and long life. For this purpose, a cold cathode tube is generally used, and a light guide plate is used to transmit uniform light to the front of the panel.
광의 균일도를 확보하기 위해 도광판의 일면에 확산시트가 채용되고, 확산시트의 일면에 광을 집광시키는 프리즘시트가 채용된다. In order to secure the uniformity of light, a diffusion sheet is employed on one surface of the light guide plate, and a prism sheet for condensing light on one surface of the diffusion sheet is employed.
이러한 백라이트 어셈블리로부터 발산된 광은 엘시디 패널에 입사되기 전에 편광필름을 통과하며, 편광필름을 통과하면서 특정방향으로 편광된 광은 C/F 기판과 TFT 기판 사이에 주입된 액정층을 통과하면서 편광성이 변하게 된다.Light emitted from the backlight assembly passes through the polarizing film before being incident on the LCD panel, and the light polarized in a specific direction while passing through the polarizing film passes through the liquid crystal layer injected between the C / F substrate and the TFT substrate. Will change.
액정층을 통과한 광은 색상을 내기 위하여 칼라필터를 통과하며, 이 칼라필터는 R, G, B 세종류가 사용되며, 칼라필터의 투과율은 일반적으로 30~35%의 투과율을 갖는다.The light passing through the liquid crystal layer passes through a color filter to produce color, and three kinds of color filters are used in R, G, and B, and the transmittance of the color filter generally has a transmittance of 30 to 35%.
칼라필터를 통과한 광은 다시 편광필름을 통과하면서 투과율이 조절된다.The light passing through the color filter passes through the polarizing film, and the transmittance is adjusted.
이와 같이 칼라 필터의 투과율이 낮아 전체적인 광투과율이 저하됨으로써 이를 극복하기 위해 칼라필터를 제거하려는 시도가 진행되고 있다. 이를 위해 엘시디 패널에 칼라필터를 사용하지 않고 색상을 구현할 수 있도록 하기 위해 백라이트 어셈블리를 각각 R,G,B의 세가지 색상으로 준비하여 R,G,B 백라이트 어셈블리의 점등시기를 조절하여 칼라를 구현할 수 있도록 하였다.As such, since the transmittance of the color filter is low, the overall light transmittance is lowered, and an attempt to remove the color filter has been made to overcome this problem. For this, the backlight assembly is prepared in three colors, R, G, and B, respectively, so that the color can be realized without using color filters on the LCD panel. It was made.
하지만, 이렇게 칼라필터를 사용하지 않고 백라이트 어셈블리를 사용함으로써 엘시디 모듈의 전체적인 두께가 증가하는 문제점이 있었다.However, there is a problem that the overall thickness of the LCD module is increased by using the backlight assembly without using the color filter.
따라서, 본 발명의 목적은 엘시디 모듈의 전체적인 두께를 줄이고 광효율을 향상시킬 수 있도록 하는데 있다.Accordingly, an object of the present invention is to reduce the overall thickness of the LCD module and to improve the light efficiency.
본 발명의 다른 목적은 다음의 상세한 설명 및 첨부된 도면으로부터 보다 명확해질 것이다.Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.
이와 같은 목적을 달성하기 위해서 본 발명의 엘시디 모듈은 상부면에 알지비(RGB) 색상을 각각 갖는 발광소자들이 상호 절연 배열된 발광부가 형성되고 발광부의 상부면에 발광소자들간에 위치하는 상호 절연 배열된 구동소자들을 갖는 구동부가 형성되며 제 1 편광막을 갖는 하부기판, 제 2 편광막, 공통전극 및 구동소자들에 대향 배열된 블랙매트릭스를 갖는 상부기판, 하부기판과 상부기판 사이에 개재되는 액정을 포함하여 이루어질 수 있다.In order to achieve the above object, the LCD module of the present invention has a light emitting part in which light emitting elements each having an RGB color are arranged insulated from each other on an upper surface thereof, and an mutual insulation array positioned between light emitting elements on an upper surface of the light emitting part. And a liquid crystal interposed between the upper substrate, the lower substrate and the upper substrate having a lower substrate having a first polarizing film, a second polarizing film, a common electrode and a black matrix arranged opposite to the driving elements. It can be made, including.
이때, 발광소자는 기판의 상부면에 형성되는 전극, 전극의 상부면에 형성되는 소정 색상을 갖는 유기발광부재, 유기발광부재의 상부면에 형성되는 투명전극으로 이루어질 수 있다.In this case, the light emitting device may include an electrode formed on the upper surface of the substrate, an organic light emitting member having a predetermined color formed on the upper surface of the electrode, and a transparent electrode formed on the upper surface of the organic light emitting member.
편광막은 발광부와 구동부 사이에 개재될 수 있다.The polarizing film may be interposed between the light emitting part and the driving part.
또한, 본 발명의 다른 엘시디 모듈은 화소전극들, 화소전극들에 전기적으로 각각 연결되는 구동소자들이 상호 절연 배열되어 형성된 구동부와 제 1 편광막을 갖는 하부기판, 하부면에 구동소자들에 각각 대향되는 알지비(RGB) 색상을 각각 갖는 발광소자들이 상호 절연 배열되어 형성된 발광부와 제 2 편광막 및 공통전극을 갖는 상부기판, 상부기판과 하부기판 사이에 개재되는 액정을 포함하여 이루어질 수도 있다.In addition, another LCD module of the present invention is opposite to the driving electrodes on the lower substrate and the lower substrate having a first polarizing film and a driving unit formed by mutually insulated the pixel electrodes and driving elements electrically connected to the pixel electrodes, respectively. The light emitting devices each having an RGB color may be formed of a light emitting part formed by insulated from each other, and an upper substrate having a second polarizing layer and a common electrode, and a liquid crystal interposed between the upper substrate and the lower substrate.
이하 첨부된 도면을 참조하여 본 발명의 기술에 따른 실시예에 의한 엘시디 모듈을 보다 상세히 살펴보면 다음과 같다. Hereinafter, an LCD module according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.
도 1을 참조하면, 엘시디 모듈은 크게 하부기판(10), 상부기판(12), 하부기판(10)과 상부기판(12) 사이에 개재되는 액정(14)으로 이루어진다.Referring to FIG. 1, an LCD module is composed of a liquid crystal 14 interposed between a lower substrate 10, an upper substrate 12, a lower substrate 10, and an upper substrate 12.
이때, 하부기판(10)은 상부면에 형성되는 알지비(RGB) 색상을 각각 갖는 발광소자들(16)이 상호 절연 배열된 발광부(18), 발광부(18)의 상부면에 형성되는 발광소자들(16)간에 위치하는 상호 절연 배열된 구동소자들(20)을 갖는 구동부(22), 발광부(18)와 구동부(22) 사이에 개재되는 제 1 편광막(24)으로 이루어진다.At this time, the lower substrate 10 is formed on the upper surface of the light emitting unit 18 and the light emitting unit 18 in which the light emitting elements 16 each having an RGB color formed on the upper surface thereof are arranged insulated from each other. And a first polarizing film 24 interposed between the light emitting portion 18 and the driving portion 22 having the driving elements 20 arranged mutually insulated between the light emitting elements 16.
발광부(18)는 도 2에 도시된 바와 같이, 기판(26)의 상부면에 형성되는 발광소자들(16)과 이 발광소자들(16)간을 절연하는 절연막(27)으로 이루어진다.As shown in FIG. 2, the light emitting unit 18 is formed of light emitting elements 16 formed on the upper surface of the substrate 26 and an insulating layer 27 insulating the light emitting elements 16 from each other.
발광소자(16)은 기판(26)의 상부면에 형성되는 전극(28), 전극(28)의 상부면에 형성되어 알지비(RGB)와 같은 소정 색상을 갖는 유기발광부재(30), 유기발광부재(30)의 상부면에 형성되는 투명전극(32)으로 이루어진다.The light emitting device 16 is an electrode 28 formed on an upper surface of the substrate 26, an organic light emitting member 30 formed on an upper surface of the electrode 28, having a predetermined color such as RGB, and organic. It is made of a transparent electrode 32 formed on the upper surface of the light emitting member (30).
이러한 발광소자(16)는 양전극(28)(30)으로부터 인가되는 전기적인 신호에 의해 유기발광부재(30)가 발광되어 소정의 색을 발산하는 구조로 이루어진다.The light emitting device 16 has a structure in which the organic light emitting member 30 emits light by an electric signal applied from the positive electrodes 28 and 30 to emit a predetermined color.
이와 같이 종래에 사용된 백라이트 어셈블리 대신에 발광소자들을 형성하여 백라이트 어셈블리와 컬러필터의 기능을 동시에 수행한다. As such, instead of the backlight assembly used in the related art, light emitting devices are formed to simultaneously perform the functions of the backlight assembly and the color filter.
구동부(22)는 기판(34)의 상부면에 형성되는 게이트 전극(36), 게이트 전극(36) 상부에 형성되는 게이트 절연막(38), 게이트 전극(36)에 대향하는 게이트 절연막(38)상에 형성되는 실리콘막(40), 실리콘막(40)상에 형성되는 소스/드레인 전극(42)(44)으로 이루어진 구동소자(20), 이 상부에 형성되는 절연막(46), 드레인 전극(44)에 형성되는 콘택홀을 통해 드레인 전극(44)과 전기적으로 연결되는 화소전극(48)으로 이루어진다.The driver 22 is disposed on the gate electrode 36 formed on the upper surface of the substrate 34, the gate insulating film 38 formed on the gate electrode 36, and the gate insulating film 38 facing the gate electrode 36.

And a pixel electrode 48 electrically connected to the drain electrode 44 through a contact hole formed in
또한, 상부기판(12)은 구동소자들(20)간에 위치하는 블랙매트릭스(50)가 기판(52)의 하부면에 형성되고, 블랙매트릭스(50)의 상부에는 공통전극(54)이 형성되며, 기판(52)의 상부면에는 편광막(55)이 형성되어 이루어진다.In addition, the upper substrate 12 has a black matrix 50 positioned between the driving elements 20 formed on the lower surface of the substrate 52, and a common electrode 54 formed on the black matrix 50. The polarizing film 55 is formed on the upper surface of the substrate 52.
이와 같이 종래에 사용된 백라이트 어셈블리 대신에 발광소자들을 형성하여 백라이트 어셈블리와 컬러필터의 기능을 동시에 수행함으로써 엘시디 모듈의 전체적인 두께를 줄임과 동시에 컬러필터로 인해 저하되는 광효율을 향상시킬 수 있다.As such, by forming light emitting devices instead of the backlight assembly used in the related art, functions of the backlight assembly and the color filter may be simultaneously performed, thereby reducing the overall thickness of the LCD module and improving the light efficiency degraded by the color filter.
한편, 도 3은 하부기판의 발광부에 대한 다른 실시예를 나타낸 것으로, 도 2에 대한 설명과 동일한 부분에 대한 상세한 설명은 생략한다.Meanwhile, FIG. 3 shows another embodiment of the light emitting part of the lower substrate, and detailed description of the same parts as those of FIG. 2 will be omitted.
