본 고안은 하나의 액정표시장치에서 투과형과 반사형을 선택하여 사용할 수 있도록 고안된 투과형과 반사형의 기능을 갖는 액정표시장치에 관한 것이다.The present invention relates to a liquid crystal display device having a transmission type and a reflection type designed to select and use a transmission type and a reflection type in one liquid crystal display device.
칼라텔레비젼이나 컴퓨터 디스플레이 등에 사용되는 대형 액정표시장치의 개략적인 구조는 다음과 같다.A schematic structure of a large liquid crystal display device used in color television or computer display is as follows.
액정표시장치는 크게 화면을 표시케 되는 패널부와 백라이트 광원부 그리고 패널에 소정의 신호전류를 입력하기 위한 구동회로부로 구분을 할 수가 있다. 액정표시장치의 패널부는 편광판 사이에 다결정 또는 비정질 실리콘 박막트랜지스터의 배열을 형성한 하부유리기판과, 적(R), 녹(G), 청(B)의 칼라필터층을 도포한 투명한 상부유리기판 사이에 액정이 봉입되어 액정층이 형성된 구조로 되어 있고, 상기한 칼라필터층과 액정층 사이에는 투명한 ITO(indium thin oxide)의 공통전극이 형성되어 있다. 상기한 박막트랜지스터는 각 화소(pixel)마다 형성되어 있기 때문에, 각 화소의 박막트랜지스터를 구동하므로써 소정의 화상을 재현하게 된다.The liquid crystal display device may be classified into a panel unit for displaying a large screen, a backlight light source unit, and a driving circuit unit for inputting a predetermined signal current to the panel. The panel portion of the liquid crystal display device includes a lower glass substrate having an array of polycrystalline or amorphous silicon thin film transistors between the polarizing plates and a transparent upper glass substrate coated with red (R), green (G), and blue (B) color filter layers. The liquid crystal is encapsulated in the liquid crystal layer, and a transparent common electrode of indium thin oxide (ITO) is formed between the color filter layer and the liquid crystal layer. Since the thin film transistor is formed for each pixel, a predetermined image is reproduced by driving the thin film transistor of each pixel.
투과형 액정표시장치에서는 액정의 배열변화에 따라서 정보를 표시케될 때에는 백라이트 광원이 필요하게 되고, 그 광원으로는 통상 일렉트로 루미네선스(Electro Luminescence)소자를 사용하고 있다.In a transmissive liquid crystal display device, a backlight light source is required when information is displayed in accordance with the change in the arrangement of liquid crystals. An electro luminescence element is usually used as the light source.
그리고 구동회로부는 인쇄회로기판(PCB)위에 소정이 전자부품이 짜넣어져서 액정패널부에 커넥터나 기타 배선수단에 의해서 연결되어 전기적 구동신호를 송출한다.In addition, a predetermined electronic component is embedded on a printed circuit board (PCB), and the driving circuit unit is connected to the liquid crystal panel by a connector or other wiring means to transmit an electric driving signal.
액정표시장치에서 신호입력은 패널부에 형성된 입력단자를 통하여 입력하게 되는 것으로서, 패널부와 기판부의 납땜조립을 위하여 패널부의 입력 단자와 기판의 출력단자를 상호 정확하게 일치되게 맞춘 소정의 열압착헤드를 접착부에 눌러서 단자간의 접착을 시킨다.In the liquid crystal display device, signal input is input through an input terminal formed in the panel portion. For soldering assembly of the panel portion and the substrate portion, a predetermined thermocompression head having the input terminal of the panel portion and the output terminal of the substrate is exactly matched with each other. Press the adhesive part to bond between terminals.
상기한 바와 같이 액정표시장치에서 정보를 표시하는 방법이 투과형일 경우에는 백라이트의 광원이 요구되고, 반사형의 경우에는 백라이트의 광원이 없어도 외부에서 조사되는 빛의 반사로 표시된 정보를 읽을 수가 있다.As described above, when the method of displaying information in the liquid crystal display device is a transmission type, a light source of a backlight is required, and in the case of a reflection type, information displayed by reflection of light emitted from the outside can be read without a light source of a backlight.
본 고안은 상술한 투과형과 반사형의 기능을 겸비한 액정표시장치를 제공함으로써, 사용자로 하여금 선택의 폭을 넓게 할 수 있는 투과형과 반사형을 겸한 액정표시장치를 제공함에 그 목적이 있다.An object of the present invention is to provide a liquid crystal display device having both a transmissive type and a reflective type, by which a user can broaden the range of selection by providing a liquid crystal display device having both the transmissive type and the reflective type.
상기 목적에 따라서 액정패널과 구동회로의 모듈부 그리고 백라이트 광원으로 구성되는 액정표시장치에 있어서, 액정패널과 백라이트의 하부에 각각 가이드 홈을 형성하고, 이들 가이드 홈에 반사판을 선택적으로 수납할 수 있게 구성함을 특징으로 한다.According to the above object, in a liquid crystal display device comprising a liquid crystal panel, a module portion of a driving circuit, and a backlight light source, guide grooves are formed in the lower portion of the liquid crystal panel and the backlight, and the reflecting plates can be selectively accommodated in these guide grooves. It is characterized by the configuration.
이하 본 고안의 이해를 돕기 위해 첨부한 도면에 따라서 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 액정표시장치(1)의 횡단면도로서 반사판(2)이 삽입되어 상태를 나타낸 것이고, 제2도는 종단면도를 나타내고 있다.FIG. 1 is a cross-sectional view of the liquid crystal display device 1 of the present invention and shows a state in which the reflecting plate 2 is inserted, and FIG. 2 is a longitudinal cross-sectional view.
액정표시장치(1)에서 정보를 표시케되는 투과형 액정패널(3)은 상부에 있고, 하부에는 구동회로로 구성되는 모듈부(4)가 있으며, 그 사이에는 백라이트(5)가 설치되는데, 이들은 테두리의 지지체(6)에 의해 상호 고정되어 있다. 지지체(6)에는 반사판(2)을 액정패널(3)의 하부와 백라이트(5)의 하부에 구분하여 삽입할 수 있도록 가이드 홈(7),(8)이 각각 형성되어 있다.The transmissive liquid crystal panel 3 which displays information in the liquid crystal display device 1 is at the upper part, and at the lower part there is a module part 4 composed of a driving circuit, between which a backlight 5 is provided. It is mutually fixed by the support body 6 of an edge. Guide grooves 7 and 8 are formed in the support 6 so that the reflecting plate 2 can be separately inserted into the lower part of the liquid crystal panel 3 and the lower part of the backlight 5.
상기한 액정표시장치(1)의 액정패널(3)은 투과형으로서 액정패널(3)의 하면에 반사판(2)이 없을 경우에는 백라이트(5)의 빛이 액정패널(3)에 봉입된 액정의 배열을 통과하므로서 정보를 읽을 수 있게 된다.The liquid crystal panel 3 of the liquid crystal display device 1 is a transmissive type, and when the reflecting plate 2 is not present on the lower surface of the liquid crystal panel 3, the light of the backlight 5 is filled with the liquid crystal encapsulated in the liquid crystal panel 3. You can read the information by passing through the array.
그러나 반사판(2)을 액정패널(3)의 하부에 형성된 가이드 홈(7)을 통하여 삽입하게 되면 액정패널(3)의 하면에 반사판이 밀착하여 붙어 있으므로 액정표시장치(1)를 반사형으로 사용할 수가 있게 된다.However, when the reflecting plate 2 is inserted through the guide groove 7 formed in the lower portion of the liquid crystal panel 3, the reflecting plate is adhered to the lower surface of the liquid crystal panel 3 so that the liquid crystal display device 1 can be used as the reflective type. It becomes the number.
액정표시장치(1)를 투과형으로 사용할 때는 백라이트(5) 하부에 형성된 가이드 홈(8)에 반사판(2')을 끼워서 백라이트(5)의 빛이 액정패널(3)에 잘 비치게 되도록 함과 동시에 백라이트(5)의 하부에서 빛을 상방향으로 반사시켜 백라이트(5)의 효과를 증대시키게 된다.When the liquid crystal display device 1 is used as a transmissive type, the reflection plate 2 'is inserted into the guide groove 8 formed under the backlight 5 so that the light of the backlight 5 is reflected on the liquid crystal panel 3 well. At the same time, the light is reflected upward from the lower part of the backlight 5 to increase the effect of the backlight 5.
그리고 액정표시장치(1)를 반사형으로 동작시킬 경우에는 액정패널(3)의 하부에 형성된 가이드 홈(7)에 반사판(2)을 삽입하여 액정패널(3)의 표면에서 입사되는 빛을 반사시키도록 하면 되고, 이때는 백라이트(5)를 꺼도 되므로 액정표시장치의 소비전력을 줄이는 효과를 기대할 수가 있게 된다.When the liquid crystal display device 1 is operated in a reflective type, a reflecting plate 2 is inserted into the guide groove 7 formed in the lower portion of the liquid crystal panel 3 to reflect light incident from the surface of the liquid crystal panel 3. In this case, since the backlight 5 may be turned off, the effect of reducing the power consumption of the liquid crystal display device can be expected.
이미 설명한 바와 같이 종래의 반투과형 액정표시장치는 콘트라스트가 떨어지는 결점이 있었지만, 본 고안이 액정표시장치(1)는 그러나 문제를 완전히 일소하여 완전한 투과형 내지는 반사형의 액정표시장치(1)를 얻을 수가 있게 된다.As described above, the conventional transflective liquid crystal display device has a disadvantage of low contrast. However, the present invention has completely eliminated the problem, so that the liquid crystal display device 1 of the transmissive or reflective type can be obtained. Will be.
이상에서 설명한 바와 같이 본 고안에 의하면 액정표시장치(1)의 액정패널(3)을 투과형과 반사형으로 변환시킬 때는 지지체(6)의 상하부에 형성된 각각의 가이드 홈(7),(8)에 반사된(2)을 선택적으로 상압하면 되므로 액정표시장치(1)를 간단하게 투과형과 반투과형으로 변경이 가능하게 되어 실용성이 기대된다.As described above, according to the present invention, when converting the liquid crystal panel 3 of the liquid crystal display device 1 into a transmissive type and a reflective type, the guide grooves 7 and 8 formed in the upper and lower portions of the support 6 are formed. Since the reflected pressure 2 can be selectively atmospheric pressure, the liquid crystal display device 1 can be easily changed into a transmissive type and a transflective type, and practicality is expected.
