Description
본 발명은 야광 표시창이 달린 액정 표시 장치에 관한 것으로, 특히 어두운 환경에서 디스플레이의 표시를 추가적인 점등없이 볼 수 있도록 디스플레이 주변에 형광막을 형성시킨 야광 표시창이 달린 액정 표시 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device having a luminous display window, and more particularly, to a liquid crystal display device having a luminous display window in which a fluorescent film is formed around a display so that the display of the display can be viewed without additional lighting in a dark environment.
종래의 핸드폰은 도 1에 도시된 것과 같이, 액정(LCD)표시영역(1)에 문자를 표시한다. 그리고, 이 영역의 주변부(2)에 기구적으로 프레임을 형성하고 있다.The conventional cellular phone displays characters in the liquid crystal display (LCD) display area 1, as shown in FIG. And the frame is mechanically formed in the peripheral part 2 of this area | region.
그런데, 밝은 곳에서 핸드폰을 사용할 때에는 표시 영역의 글자가 뚜렷하게 보이지만 어두운 곳에서는 플립을 열어서 표시영역 후면에 장착된 램프가 켜져야만 문자를 식별할 수 있었다. 따라서, 밤거리나 야외의 조명이 약한 곳에서 핸드폰의표시 상태를 확인하거나 사용할 때에는 반드시 램프를 켜야만 했었다. 이로 인해, 배터리의 소모가 늘어나 통화가능시간이 단축되는 등의 문제점이 있었다.By the way, when using a mobile phone in a bright place, the letters of the display area are clearly visible, but in the dark place the letters mounted on the back of the display area can be identified by opening the flip. Therefore, the lamp had to be turned on when checking or using the display status of the mobile phone at night or outdoors. For this reason, there is a problem that the consumption time of the battery is increased and the talkable time is shortened.
따라서, 본 발명은 상기 문제점을 해결하기 위하여 이루어진 것으로, 본 발명의 목적은 핸드폰의 표시영역 주변부에 형광막을 도포하여 어두운 곳에서도 램프의 점등없이 쉽게 핸드폰의 수신 상태를 알 수 있도록 한 야광 표시창이 달린 액정 표시 장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to apply a fluorescent film to the periphery of the display area of the mobile phone so that the reception state of the mobile phone can be easily seen without lighting of a lamp even in a dark place. It is to provide a liquid crystal display device.
상기 목적을 달성하기 위하여, 본 발명의 야광 표시창이 달린 액정 표시 장치는,In order to achieve the above object, the liquid crystal display device with a luminous display window of the present invention,
문자 정보를 나타내어 주는 표시 영역부와,A display area portion representing character information;
상기 표시 영역부의 외곽 둘레에 형광막이 도포된 표시영역 주변부를 포함하여 구성된 것을 특징으로 한다.And a periphery of the display area coated with a fluorescent film around the periphery of the display area.
본 발명의 야광 표시창이 달린 액정 표시 장치에 있어서, 상기 형광막은 여러 가지 색상의 형광막을 선택적으로 사용한 것을 특징으로 한다.In the liquid crystal display device having a luminous display window of the present invention, the fluorescent film is characterized by selectively using a fluorescent film of various colors.

이하, 본 발명의 실시예에 관하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
또, 실시예를 설명하기 위한 모든 도면에서 동일한 기능을 갖는 것은 동일한 부호를 사용하고 그 반복적인 설명은 생략한다.In addition, in all the drawings for demonstrating an embodiment, the thing with the same function uses the same code | symbol, and the repeated description is abbreviate | omitted.
도 2는 본 발명에 의한 야광 표시창이 달린 액정 표시 장치의 구성을 나타낸 것으로, 문자 정보를 나타내어 주는 표시 영역부(10)와, 상기 표시 영역부(10)의외곽 둘레에 설치된 금형에 형광막이 도포된 표시영역 주변부(20)를 나타낸 것이다.FIG. 2 shows a configuration of a liquid crystal display device having a luminous display window according to the present invention, in which a fluorescent film is applied to a display area portion 10 for displaying character information and a mold provided around the outside of the display area portion 10. The periphery of the display area 20 is shown.
상기 표시 영역부(10)는 핸드폰의 기기가 제공하는 여러 가지의 문자를 디지털로 표시하여 주는 표시창으로, 어두운 곳에서는 문자 인식이 어렵기 때문에 표시창 후면에 설치된 램프를 작동시켜 문자를 표시하도록 한다.The display area 10 is a display window that digitally displays various characters provided by a device of a mobile phone. Since the character recognition is difficult in a dark place, the display area 10 operates a lamp installed at the rear of the display window to display the characters.
상기 표시영역 주변부(20)는 주로 플라스틱 금형의 표면에 형광막을 도포하여 주변 조명의 역할을 하도록 처리된다. 이때, 사용된 형광막은 여러 가지 색상의 형광막을 선택적으로 사용하여 소비자의 기호에 맞게 제품을 다양화 할 수 있다.The display area peripheral portion 20 is mainly processed to serve as ambient lighting by applying a fluorescent film on the surface of the plastic mold. In this case, the used fluorescent film can selectively use various colors of the fluorescent film to diversify the product according to the consumer's preference.
본 발명은 LCD 표시 영역 주변에 형광막(surrounding fluorescent layer)을 형성하여 어두운 환경에서도 약간의 주변광만 있어면 문자를 인식할 수 있게 된다. 이것은 형광막에 들어온 빛이 형광막의 빛을 문자 표시 영역으로 집광시켜 주는 역할을 하기 때문이다.According to the present invention, a fluorescent film is formed around the LCD display area so that a character can be recognized if there is only a little ambient light in a dark environment. This is because the light entering the fluorescent film condenses the light of the fluorescent film into the character display area.
본 발명은 플립형 핸드폰 뿐 아니라 폴드형 핸드폰의 듀얼 LCD의 바깥창에도 적용할 수 있으며, 기타 소형 LCD 제품군에 적용할 수 있다.The present invention can be applied to the outer window of the dual LCD of the fold-type mobile phone as well as the flip-type mobile phone, it can be applied to other small LCD family.
이상에서 설명한 바와 같이, 본 발명에 의한 야광 표시창이 달린 액정 표시 장치는, 기존의 핸드폰과는 달리 표시영역 주변부에 형광막을 도포하여 조명이 어두운 곳에서도 완전 암흑 상태만 아니면 집광된 빛이 표시영역 주위의 형광막에 의해 발광하게 되어 어두운 곳에서도 쉽게 핸드폰의 수신 상태를 알수 있다. 따라서, 플립을 열거나 폴드를 열어 젖힐 필요없이 저전력 소모 구조의 핸드폰을 제공할 수 있다. 또한, 다양한 색상(color)의 형광막을 선택적으로 도포하여 신세대 감각에 맞는 디자인 제품을 제공할 수 있다.As described above, in the liquid crystal display device having the luminous display window according to the present invention, unlike a conventional mobile phone, a fluorescent film is applied to the periphery of the display area so that the collected light is collected around the display area except in a completely dark state even in a dark place. It emits light by the fluorescent film, so you can easily know the reception status of your phone even in the dark. Thus, a cell phone having a low power consumption structure can be provided without having to open a flip or open a fold. In addition, by selectively applying a fluorescent film of a variety of colors (color) can provide a design product for the new generation sense.
아울러 본 발명의 바람직한 실시예들은 예시의 목적을 위해 개시된 것이며, 당업자라면 본 발명의 사상과 범위 안에서 다양한 수정, 변경, 부가등이 가능할 것이며, 이러한 수정 변경등은 이하의 특허청구범위에 속하는 것으로 보아야 할 것이다.In addition, preferred embodiments of the present invention are disclosed for the purpose of illustration, those skilled in the art will be able to various modifications, changes, additions, etc. within the spirit and scope of the present invention, these modifications and changes should be seen as belonging to the following claims. something to do.
