Description
본 고안은 전자잉크를 이용한 메세지 표시장치에 관한 것으로 더욱 상세하게는 극성을 가지는 마이크로 전자잉크를 수용한 전자잉크시트 저면에 도트메트리스를 결합하여, 표시하고자하는 형태의 문자나 도형으로 인쇄하고, 일정한 시간에 따라 극성이 변하는 전류를 흐르도록 하여, 표시되는 타이틀이 시간 따라 변화하므로 시각적으로 고객의 시선을 집중시켜 지속적으로서 광고효과를 증대시키는 전자잉크를 이용한 메세지 표시장치에 관한 것이다.The present invention relates to a message display apparatus using an electronic ink, and more particularly, a dot matrix is combined with the bottom surface of an electronic ink sheet containing a polarized micro electronic ink, and printed with a character or a figure of a form to be displayed, The present invention relates to a message display apparatus using an electronic ink that allows a current to change in polarity with time to flow, and thus a displayed title changes with time, thereby visually focusing on the customer's eyes and continuously increasing the advertising effect.
거리나 실내에서 현재 많이 사용되고 있는 광고판으로는, 플렉스 간판이나, 단순히 문자나 도형이 형성되거나 부착되어 있는 간판, 투명 또는 불투명 배경판의 뒤쪽에 형광등이나 네온등이 설치되어 있는 간판 등을 들 수 있다.The billboards that are commonly used in the streets and indoors include flex signs, signs with letters and figures formed or attached, signs with fluorescent lights or neon lights behind the transparent or opaque background. .
그런데, 이러한 구조는 전력을 많이 소모할 뿐만 아니라, 고전압으로 인하여 감전의 위험이 상존하고 있었다.However, such a structure consumes not only a lot of power, but also a risk of electric shock exists due to high voltage.
따라서 근래에는 이러한 문제를 해결하고 보다 깔끔한 광고효과를 얻기 위해 문자나 도형이 있는 부분만을 돌출시켜서 조명하는 채널형 광고표시장치이 채용되고 있다. 즉 종래에는 먼저 소정 두께의 아크릴판과 함석, 철판 갈바, 알루미늄 등을 정해진 문자나 도형으로 가공하고, 그 뒤쪽에 LED 기판을 배치하였다.Therefore, in recent years, in order to solve such a problem and to obtain a cleaner advertisement effect, a channel type advertisement display device that protrudes and illuminates only a part having a letter or a figure is adopted. That is, conventionally, the acrylic plate, the tin, the iron plate galvan, the aluminum, etc. of a predetermined thickness were first processed into predetermined letters or figures, and the LED substrate was disposed behind them.
상기 아크릴판과 LED 기판 사이의 간격은 채용된 LED의 조사 각도(15°, 20°, 30°,45°, 90°, 120°, 140° 등)에 따라 최적의 선명도를 나타내도록 적절히 결정될 수 있다.The spacing between the acrylic plate and the LED substrate can be appropriately determined to show the optimal sharpness depending on the irradiation angle (15 °, 20 °, 30 °, 45 °, 90 °, 120 °, 140 °, etc.) of the LED employed. have.
그러나, 이와 같은 종래의 LED를 이용한 광고표시장치의 구조에 있어서는, 아크릴판과 LED 기판 사이에 간격이 형성되어 있기 때문에, 앞뒤 고정 프레임에 밑판, 조명판, 트림, 테두리, 용접, 도장, 접착제, 피스 고정작업 등을 각각 별도로 진행하여 결합될 수 밖에 없어 작업 자체가 번거로웠을 뿐만 아니라, 작업 시간이 많이 소모되어 가격이 상승하는 등의 문제점이 있었다.However, in the structure of an advertisement display device using such a conventional LED, since the gap is formed between the acrylic plate and the LED substrate, the bottom plate, lighting plate, trim, frame, welding, painting, adhesive, There was a problem that the work itself is cumbersome, as well as the work of fixing the pieces separately to be combined separately, and the cost increases due to a lot of working time.
따라서 본 고안 전자잉크를 이용한 메세지 표시장치은 상기한 제반 문제점을 해소하기 위해 극성을 가지는 마이크로 전자잉크를 수용한 전자잉크시트 저면에 도트메트리스를 결합 구성한 디스플레이판과, 표시하고자하는 형태의 문자나 도형으로 연산, 저장, 제어하는 콘트롤러가 구성된 표시부를 구성하여, 디스플레이판의 타이틀이 시간 따라 변화하므로 시각적으로 고객의 시선을 집중시켜 지속적으로서 광고효과를 증대시킴으로써, 다양한 정보를 입체적인 디자인으로 시각적인 요소와 함께 사용자에게 제공하여 사용자의 구매의욕을 촉진 시킴과 동시에 광고주의 욕구를 충족시킬 수 있는 기업홍보나 제품판촉용도로서 적합한 실용적인 고안이며, 또한 본 고안에 따른 메세지 표시장치는 부피 및 무게가 가벼워 설치가 용이하고, 다른 디스플레이장치보다 내구력이 우수하여 유지보수도 용이하며, 이로 인해 제품의 품질과 신뢰성을 대폭 향상시켜 소비자로 하여금 좋은 이미지를 심어줄 수 있는 전자잉크를 이용한 메세지 표시장치를 제공하는데 그 목적으로 하고 있다.Therefore, the message display device using the electronic ink according to the present invention has a display panel in which a dot matrix is coupled to the bottom surface of an electronic ink sheet containing a micro electronic ink having a polarity in order to solve the above problems, and a character or a figure of a form to be displayed. The display panel is composed of a controller that operates, stores, and controls. As the title of the display panel changes with time, the customer's eyes are visually focused to continuously increase the advertising effect. Providing to the user to promote the user's desire to purchase and at the same time, it is a practical design suitable for corporate promotional or product promotion purposes that can meet the needs of advertisers, and the message display device according to the present invention is easy to install due to light volume and weight And other displays Also it facilitates maintenance and durability are superior to the device, which causes has as its objective to significantly improve the quality and reliability of the product allows the consumer to provide a message display device using electronic ink that can instill a good image.
