본 발명은 투명디스플레이 양면에 변색필름을 부착하여, 디스플레이 화면의 시인성을 개선하고자 하는 변색필름이 양면에 부착된 투명디스플레이 장치 및 그 제조방법에 관한 것이다.The present invention relates to a transparent display device having a color-changing film attached to both sides of a transparent display to improve visibility of a display screen by attaching a color-changing film to both sides of a transparent display, and a method for manufacturing the same.

이하에서는 첨부된 도면을 참조하여 본 발명에 대해 상세히 설명하고자 한다. 도 1 내지 도 3은 본 발명의 다양한 실시예에 따른 변색필름이 양면에 부착된 투명디스플레이 장치에 대한 모식도이다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 are schematic diagrams of a transparent display device having a discoloration film attached to both sides according to various embodiments of the present invention.

도시된 바와 같이 본 발명에 따른 변색필름이 양면에 부착된 투명디스플레이 장치는, 투명디스플레이와, 상기 투명디스플레이 양면에 부착된 변색필름을 포함하는 것을 특징으로 한다.As shown, the transparent display device having the discoloration film attached to both sides according to the present invention includes a transparent display and the discoloration film attached to both sides of the transparent display.

상기 변색필름은, 외부 자극을 이용하여 투명도가 변하는 것으로, 외부 자극이라 함은 전기, 빛 등 변색을 하도록 유도하는 모든 자극을 포함할 수 있다. 본 발명의 일실시예로, EC, SPD, 칼라 PDLC 등이 이에 해당할 수 있다.The discoloration film has a change in transparency using external stimuli, and the external stimuli may include all stimuli that induce discoloration, such as electricity and light. As an embodiment of the present invention, EC, SPD, color PDLC, and the like may correspond to this.

본 발명은 투명디스플레이 양면에 상기 변색필름이 부착된 것으로, 변색필름의 투명도를 조절하여 단면 또는 양면 시청이 가능하게 하도록 한 것이다. 즉, 가시성을 향상시켜 양면에서 화면을 볼 수 있도록 한 투명디스플레이 장치를 제공하는 것이다.In the present invention, the discoloration film is attached to both sides of a transparent display, and the transparency of the discoloration film is adjusted to enable single-sided or double-sided viewing. That is, to provide a transparent display device capable of viewing a screen from both sides by improving visibility.

본 발명은 기존에 한면에만 변색필름 또는 암막필름을 부착하여 필름이 부착된 반대면에서만 화면을 잘 볼 수 있도록 고안된 제한된 디스플레이 구조를 양면에서 볼 수 있도록 하여, 디스플레이 활용 범위를 넓히는 것과 동시에 이에 따라 낮과 밤 또는 안과 밖 모두에서 디스플레이되는 화면을 더욱 잘 볼 수 있도록 한 것이다.The present invention expands the range of display utilization and lower and at night, or both inside and outside, the displayed screen can be seen better.

즉, 본 발명은 변색필름을 투명디스플레이의 양면에 부착되도록 구성하여 디스플레이 방향에 따라 변색필름의 투명도를 개별 조절하여 원하는 면에서 화면이 잘 보이도록 구성한 것이다.That is, the present invention configures the color-changing film to be attached to both sides of the transparent display, and individually adjusts the transparency of the color-changing film according to the display direction so that the screen can be seen well on the desired side.

또한 본 발명은 디스플레이가 건물의 창으로 설치될 경우, 낮에는 바깥면의 변색필름을 어둡게 하여 외부로부터의 빛을 차단하여 건물 안에서 창 쪽으로 바라볼 때 디스플레이의 화면에 맺히는 화상이 더욱 잘 보이게 하고, 밤에는 안쪽면의 변색필름을 어둡게 하여 건물 밖에서부터 건물을 향하여 볼 때 디스플레이 화면에 맺히는 화상이 더욱 잘 보이게 하도록 한 것이다. 본 발명의 구조를 자동차의 유리로 설치했을 때에도 마찬가지의 효과를 가질 수 있다.In addition, the present invention, when the display is installed as a window of a building, darkens the discoloration film on the outer surface during the day to block light from the outside so that the image formed on the screen of the display is more visible when looking toward the window from inside the building, At night, the discoloration film on the inner surface is darkened so that the image formed on the display screen is more visible when viewed from outside the building toward the building. The same effect can be obtained even when the structure of the present invention is installed on the glass of a vehicle.

본 발명의 일실시예에 따르면, 상기 투명디스플레이 일면에 부착된 변색필름과 타면에 부착된 변색필름은, 서로 다른 두께 또는 서로 다른 물질로 이루어질 수 있다.According to one embodiment of the present invention, the color-changing film attached to one surface of the transparent display and the color-changing film attached to the other surface may be made of different thicknesses or different materials.

즉, 상술한 바에 따라, 건물의 창에 적용될 경우, 안쪽의 변색필름과 바깥쪽의 변색필름의 두께를 서로 다르게 하거나, 서로 다른 물질로 형성되게 할 수 있다.That is, as described above, when applied to a window of a building, the thickness of the discoloration film on the inside and the discoloration film on the outside may be different from each other or made of different materials.

이는 내외부 온도 차이나 습도 차이와 같은 내외부 환경 차이에 따른 변색필름의 내구성 및 작동성을 개선하기 위한 것이다. 즉, 온도에 따른 변형이나 비바람에 따른 변형에 따른 내구성 및 작동성을 개선하기 위한 것이다.This is to improve durability and operability of the discoloration film according to internal and external environmental differences such as internal and external temperature and humidity differences. That is, it is intended to improve durability and operability due to deformation due to temperature or deformation due to wind and rain.

또한 디스플레이 화면의 시인성을 더욱 개선하기 위해서, 상기 변색필름의 일면에는 안티 글레어(Anti glare) 처리나, 안티 리플렉션(Anti reflection) 처리가 더 구현될 수 있다.In addition, in order to further improve the visibility of the display screen, anti-glare treatment or anti-reflection treatment may be further implemented on one surface of the discoloration film.

또한, 본 발명에 따른 일실시예로, 상기 투명디스플레이 일면에 부착된 변색필름과 타면에 부착된 변색필름은, 각각 투명도를 개별조절할 수 있어, 주변 밝기에 따른 적용 가변성이 우수하다.In addition, in one embodiment according to the present invention, the color-changing film attached to one side of the transparent display and the color-changing film attached to the other side can individually control the transparency, respectively, so that the application variability according to the ambient brightness is excellent.

도 1은 본 발명의 일실시예에 따라, 양면의 변색필름이 모두 어두운 상태를 나타낸 것으로, 이 상태에서는 어떤 면에서도 화상이 보이지 않는다.1 shows a state in which both discoloration films are dark according to an embodiment of the present invention, and in this state, images are not visible on any side.

도 2는 본 발명의 일실시예에 따라, 안쪽의 변색필름은 투명한 상태이고 바깥쪽의 변색필름은 어두운 상태를 보인 것이다. 이 상태에서는 안쪽에서 화면을 볼 경우 잘 보이고 바깥 쪽에서는 화면이 보이지 않는다.2 shows an inner discoloration film in a transparent state and an outer discoloration film in a dark state according to an embodiment of the present invention. In this state, the screen looks good when viewed from the inside, but the screen is not visible from the outside.

도 3은 본 발명의 일실시예에 따라, 안쪽의 변색필름은 어두운 상태이고 바깥쪽의 변색필름은 투명한 상태를 보인다. 이 상태에서는 안쪽에서는 화면이 잘 보이지 않고 바깥 쪽에서는 화면이 잘 보인다.Figure 3 shows an inner discoloration film in a dark state and an outer discoloration film in a transparent state according to an embodiment of the present invention. In this state, the screen is not visible from the inside and the screen is visible from the outside.

즉, 도 3의 경우 외부 빛의 환경과 무관하며 만일 변색필름이 양면 모두 투명하게 조절될 경우 외부 빛의 환경에 따라 밝을 경우 디스플레이 화면의 화상이 잘 보이지 않으며 어두울 경우 화상이 잘 보일 수도 있다.That is, in the case of FIG. 3, the external light environment is irrelevant, and if both sides of the discoloration film are adjusted to be transparent, the image on the display screen is not easily visible depending on the external light environment when it is bright, and when it is dark, the image may be well visible.
