Description

횡전계 방식 전기 영동 표시장치{In Plain Electrophoretic Display Device}Transverse Electrophoretic Display Device {In Plain Electrophoretic Display Device}

본 발명은 횡전계 방식 영동 표시장치(In Plain Electrophoretic Ddisplay : IP EPD)에 관한 것으로 특히, 투과형 횡전계 방식 전기영동 표시장치에 관한 것이다.The present invention relates to an In Plain Electrophoretic Ddisplay (IP EPD), and more particularly to a transmissive transverse electrophoretic display.

일반적으로, 표시장치는 스스로 빛을 내어 표시하는 발광형과 인위적 또는 자연적 빛을 이용하여 이미지를 표시하는 수광형으로 나눌 수 있다.In general, the display device may be classified into a light emitting type which emits light by itself and a light receiving type which displays an image using artificial or natural light.

발광형 표시장치는 대표적으로 플라즈마 표시장치와 유기전계 발광 표시장치를 들 수 있으며, 수광형 표시장치로는 액정표시장치와 전기 영동 표시장치를 들 수 있다.Representative examples of the light emitting display include a plasma display and an organic light emitting display, and examples of the light receiving display include a liquid crystal display and an electrophoretic display.

상기 전기 영동 표시장치는 전기 영동 현상을 이용한 표시장치로서 이하, 도 1을 참조하여 종래에 따른 전기영동 표시장치의 구성을 설명한다.The electrophoretic display device is a display device using an electrophoretic phenomenon. Hereinafter, a configuration of a conventional electrophoretic display device will be described with reference to FIG. 1.

도 1은 종래에 따른 반사형 전기 영동 표시장치를 개략적으로 도시한 확대 단면도이다.1 is an enlarged cross-sectional view schematically illustrating a conventional reflective electrophoretic display device.

도시한 바와 같이, 전기 영동 표시장치(10)는 스위칭 소자(T)와 전극이 구성된 제 1 기판(12)과 제 2 기판(30)이 블랙 입자(24)을 포함하고 이와는 반응하지 않는 용매(22)를 사이에 두고 합착되어 구성된다. 보통 상기 용매(22)는 투명한 상태를 나타낸다.As illustrated, the electrophoretic display 10 includes a solvent in which the first substrate 12 and the second substrate 30 including the switching element T and the electrode include black particles 24 and do not react with the black particles 24 ( It is composed by being joined with 22) in between. Usually the solvent 22 is in a transparent state.

상기 제 1 기판(12)은 다수의 화소(P)가 정의되며, 각 화소(P)마다 서로 다른 특성을 가지는 제 1 전극(14)과 제 2 전극(18)과, 스위칭 소자(미도시)가 구성된다.The first substrate 12 has a plurality of pixels P defined therein, the first electrode 14 and the second electrode 18 having different characteristics for each pixel P, and a switching element (not shown). Is composed.

전술한 제 1 기판(12)의 구성을 좀더 상세히 설명하면, 절연기판인 제 1 기판(12)의 전면에 제 1 전극(14)을 구성되고, 상기 제 1 전극(14)의 상부에는 절연막(16)을 사이에 두고 제 2 전극(18)을 구성한다.When the above-described configuration of the first substrate 12 is described in more detail, a first electrode 14 is formed on the entire surface of the first substrate 12, which is an insulating substrate, and an insulating film is formed on the first electrode 14. The 2nd electrode 18 is comprised with 16 in between.

이때, 상기 제 2 전극(18)은 화소의 양측에 각각 나누어져 구성될 수 있으며, 상기 서로 근접한 제 2 전극(18)의 하부(즉 화소의 경계)에는 블랙매트릭스(17)가 구성된다.In this case, the second electrode 18 may be divided on both sides of the pixel, and the black matrix 17 is formed below the second electrode 18 adjacent to each other (ie, the boundary of the pixel).

상기 제 1 전극(12)은 반사율이 뛰어난 전도성 금속 중 선택된 하나를 증착하여 형성하게 되는데, 대표적으로 알루미늄(Al)을 예로 들 수 있다.The first electrode 12 is formed by depositing a selected one of the conductive metals having excellent reflectance, for example, aluminum (Al).

상기 제 2 전극(18)은 티타늄(Ti)으로 형성할 수 있으며, 제 2 전극의 표면은 블랙 수지가 코팅되어 있다.The second electrode 18 may be formed of titanium (Ti), and the surface of the second electrode is coated with a black resin.

상기 제 1 전극(14)은 접지에 연결되고, 상기 제 2 전극(18)은 (+)또는 (-)전압이 인가될 수 있다.The first electrode 14 is connected to the ground, and the second electrode 18 may be applied with a positive or negative voltage.

상기 블랙 입자가 (+)로 대전되었다고 가정하였을 경우, 이하 2a와 도 2b를 참조하여, 블랙상태와 화이트 상태를 표시하는 상기 반사형 전기영동 표시장치의 동작특성을 설명한다.If it is assumed that the black particles are charged with (+), the operation characteristics of the reflective electrophoretic display device displaying the black state and the white state will now be described with reference to 2a and 2b.

도 2a는 블랙상태를 나타내는 전기 영동 표시장치의 구성을 개략적으로 도시한 단면도이다.2A is a cross-sectional view schematically showing the configuration of an electrophoretic display device showing a black state.

도시한 바와 같이, 제 1 전극(14)은 접지와 연결되고, 제 2 전극에 (+)전압이 인가되며, 상기 (+)로 대전된 블랙 입자(24)은 전위가 낮은 제 1 전극(14)의 상부에 넓게 퍼져 위치하게 된다.As shown, the first electrode 14 is connected to the ground, a positive voltage is applied to the second electrode, and the black particles 24 charged with the (+) have a low potential first electrode 14. It will be spread over the top of the pan.

이와 같은 경우에는 외부에서 입사한 빛이 상기 블랙 입자(24)에 흡수 되기 때문에 블랙 상태(black state)를 표시하게 된다.In this case, since the light incident from the outside is absorbed by the black particles 24, the black state is displayed.

반대로, 도 2a에 도시한 바와 같이, 상기 제 1 전극(14)이 접지에 연결되고, 제 2 전극에 (-)전압을 인가하게 되면, 상기 (+)로 대전된 블랙 입자(24)은 전위가 낮은 제 2 전극(18)의 상부로 움직이게 되어 외부로부터 입사된 빛은 상기 제 1 전극(16)에 반사되기 때문에 화이트 상태(white state)를 표시하게 된다.On the contrary, as shown in FIG. 2A, when the first electrode 14 is connected to ground and a negative voltage is applied to the second electrode, the black particles 24 charged with the (+) are dislocations. Is moved to the upper portion of the lower second electrode 18 so that light incident from the outside is reflected by the first electrode 16, thereby indicating a white state.

전술한 바와 같은 전기적인 동작을 통해 종래에 따른 전기 영동장치가 화이트와 블랙 상태로서 이미지를 표현하게 된다.As described above, the electrophoretic apparatus according to the related art expresses an image as white and black states.

그러나, 전술한 바와 같은 종래의 반사형 전기 영동 표시장치는 외부의 빛을 이용하기 때문에, 장소에 따라 제약이 따르고 충분한 휘도를 얻지 못하기 때문에 전반적으로 화질이 좋지 못한 문제가 발생한다.However, since the conventional reflective electrophoretic display uses the external light as described above, there is a problem in that the image quality is poor due to limitations in some places and insufficient luminance.

본 발명은 전술한 문제를 해결하기 위해 제안된 것으로, 상기 전기 영동 표시장치에 컬러필터를 구성하고 하부 기판에 배광장치를 구성하여, 고 휘도 및 고 콘트라스트를 구현하는 전기 영동 표시장치를 제작하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-described problem, and to fabricate a color filter on the electrophoretic display device and a light distribution device on a lower substrate, thereby manufacturing an electrophoretic display device having high brightness and high contrast.

이때, 상기 제 1 전극(104)은 인듐-틴-옥사이드(ITO)와 인듐-징크-옥사이드(IZO)를 포함하는 투명한 도전성 금속물질 중 선택된 하나로 형성한다.In this case, the first electrode 104 is formed of one selected from a transparent conductive metal material including indium tin oxide (ITO) and indium zinc oxide (IZO).

상기 제 1 전극(104)의 상부에는 절연막(106)을 사이에 두고 각 화소(P)마다 스위칭 소자(미도시)가 구성되고, 상기 스위칭 소자(미도시)와 연결된 제 2 전극(108)을 형성한다.A switching element (not shown) is configured for each pixel P with an insulating layer 106 interposed therebetween, and the second electrode 108 connected to the switching element (not shown) is disposed on the first electrode 104.
