Description

전기, 전자기기용 제어판넬{Control panel for electric/electronic device}Control panel for electric and electronic devices {Control panel for electric / electronic device}

본 발명은 자동차 계기판이나 세탁기, 복사기, 휴대폰 등과 같이 표시부의 발광을 요하는 각종 전기, 전자기기에 이용되는 제어판넬에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control panel used for various electric and electronic devices that require light emission of a display unit such as an automobile instrument panel, a washing machine, a copy machine, a mobile phone, and the like.

각종 전기, 전자기기의 제어판넬은 모든 동작이 해당 표시구의 발광으로 표시되게 한 것으로서, 그 발광수단으로서는 크게 평면 발광소자(E.L램프)와 발광다이오드로 구분되며, 이러한 발광수단에 따라 두제품은 서로 상반된 장단점을 지니고 있다.The control panel of various electric and electronic devices allows all operations to be displayed by emitting light of the corresponding indicator. The light emitting means is largely divided into a flat light emitting device (EL lamp) and a light emitting diode. It has opposite advantages and disadvantages.

즉 평면 발광소자(E.L램프)는 입자화된 도전물질이 진공증착된 특수필름(ITOFILM)에 형광층과 절연층과, 도전층과 방습 및 절연층을 차례로 형성하여 인버터를 통한 교류전기의 공급으로 발광되게 한 것으로서, 이는 두께가 얇아 설치공간을 줄일 수 있고, 또 두께가 얇아 설치공간을 줄일 수가 있고 제품을 소형화 및 슬림화 할 수 있는 장점을 지니게 되나, 도전물질이 진공증착된 필름은 일반필름에 훨씬 고가로 거래되므로 제조경비가 상승하게 되고, 특히 3차원의 입체적인 형상은 얻을 수가 없어 부착면이 평면인 조건의 일부 제품으로 이용폭이 극히 제한되며, 이로 인하여 디자인을 다양화 할 수가 없는 단점을 지니게 된다.That is, the planar light emitting device (EL lamp) forms a fluorescent layer, an insulating layer, a conductive layer, a moisture proof and an insulating layer in order on the special film (ITOFILM) in which the granulated conductive material is vacuum-deposited, and supplies AC electricity through an inverter. It is made to emit light, which is thin, which can reduce the installation space, and the thickness can reduce the installation space, and it has the advantage of miniaturization and slimming of the product. As it is much more expensive, the manufacturing cost increases, and in particular, the three-dimensional three-dimensional shape cannot be obtained, so the range of use is extremely limited to some products having a flat surface, and thus the design cannot be diversified. Will be carried.

또한 발광다이오드(LED)를 발광수단으로 하는 제품은 일반 투명필름 이면에 인몰드(IN MOLD) 전용잉크와 접착제를 차례로 도포한 다음 이를 인서트 사출성형하여 구성되는 표시판과, 이 역시 사출 성형되는 구조물 및 상기 구조물에 지지되는 여러개의 발광다이오드와 I.C칩 등으로 구성되므로 이는 인서트 사출성형으로 표면의 표시부를 3차원의 입체적으로 나타내줄 수가 있어 부착면이 평면에서부터 곡면에 이르기까지 아무런 제약없이 이용할 수가 있고, 또 이를 토대로 제품의 디자인을 다양화 할 수가 있는 장점을 지니게 되나, 이 역시 별도의 구조물과 각 표시창별 별도의 여러개의 발광다이오드를 필요로 하므로 제조경비가 상승하게 되고, 부피가 커 설치공간을 많이 차지하게 되며, 이로 인하여 점차 소형화, 슬림화추세에 있는 업계요구에 부응할 수가 없는 단점을 지니게 된다.In addition, the product using the light emitting diode (LED) as a light emitting means is applied to the back of the general transparent film, the in-mold (In MOLD) dedicated ink and the adhesive is applied to the display panel formed by insert injection molding, and this also the injection molded structure and Since it is composed of several light emitting diodes and IC chips supported on the structure, it is possible to display the display part of the surface in three dimensions by insert injection molding, so that the attachment surface can be used without any restrictions from flat to curved surfaces. In addition, it has the advantage of diversifying the design of the product on the basis of this, but this also requires a separate structure and a separate light emitting diode for each display window, thereby increasing the manufacturing cost, large volume and installation space As a result, it will be able to meet the industry's demand for miniaturization and slimming. It has a number of disadvantages.

또한 이러한 평면 발광소자를 이용한 제어판넬과, 발광다이오드를 이용한 제어판넬의 장점만을 갖는 제품을 얻고자 단순히 기존의 평면 발광소자를 인서트 사출 성형하여 구성할 경우 기본적으로는 도전층을 갖는 특수필름(ITO FILM)의 비싼구입가격으로 제조단가의 상승요인은 잔존하게 되고, 또 필름이면의 도전층은 분말화된 도전물질을 진공증착하여 구성함에 따라 사출 성형시 가해지는 약 250℃의 고열에서 필름이 입체적으로 변형되는 과정에서 박리현상이 발생되고, 또 이러한 박리현상 및 필름으로부터의 높은 열전도율로 형광층이 파괴 내지는 녹아내려 해당표시창은 발광성을 잃게 되므로 제어판넬로서의 기능을 전혀 발휘할 수가 없어 이제껏 양자가 갖는 장점만을 취합한 구조의 제어판넬은 전혀 얻을 수 없는 것으로 여겨지고 있다.In addition, in order to obtain a product having only the advantages of the control panel panel using the planar light emitting device and the control panel using the light emitting diode, a special film having an electrically conductive layer (ITO) is basically provided when the conventional planar light emitting device is simply formed by insert injection molding. Due to the high purchase price of FILM, the increase in manufacturing cost remains, and the conductive layer on the back of the film is formed by vacuum evaporation of powdered conductive material. In this process, the peeling phenomenon occurs, and the fluorescence layer is destroyed or melted due to such peeling phenomenon and high thermal conductivity from the film, so that the corresponding display window loses its luminescence. It is believed that a control panel with a bay structure cannot be obtained at all.

이에 본 발명은 평면 발광소자로 구성되는 제어판넬과 발광다이오드로 구성되는 제어판넬이 갖는 장점만을 취합하여 값싼 경비로 제작할 수가 있고, 또 슬림화하면서도 인서트 사출 성형으로 3차원의 입체적인 형상을 얻을 수가 있는 제어판넬을 제공함에 그 목적이 있다.Therefore, the present invention can be manufactured at low cost by combining only the advantages of the control panel panel consisting of a flat light emitting device and the control panel consisting of a light emitting diode, and controlling the slimming and obtaining three-dimensional shape by insert injection molding. The purpose is to provide a panel.

상기한 목적달성을 위하여 본 발명은 일반 투명필름 이면에 각기 주재가 수지계열인 보호층과 도전층과 형광층과 유전층과 보호층을 차례로 형성하여 발광소자부를 구성하고, 상기 발광소자부는 이면에 도포되는 접착제를 이용하여 인서트 사출 성형하여 구성함을 특징으로 한다.In order to achieve the above object, the present invention forms a light emitting device unit by sequentially forming a protective layer, a conductive layer, a fluorescent layer, a dielectric layer, and a protective layer, each of which is mainly resin-based, on the back surface of a general transparent film, and the light emitting device portion is coated on the back surface. It is characterized in that the injection molding using the adhesive is configured.

상기에 있어 인몰드용 보호층(4)(12)과 도전층(6)(11)과 형광층(8)과, 유전층(10)은 일반적인 것으로서, 구체적인 혼합물질과 비율 등은 생략하기로 하며, 다만 각기 요구되는 기본적인 성질을 갖는 것이면 만족한다.In the above, the in-mold protective layer (4) (12), the conductive layer (6) (11), the fluorescent layer (8), and the dielectric layer (10) are general, and specific mixtures and ratios will be omitted. Provided that they have the basic properties required.

본 발명은 발광소자부 이면에 적정두께의 합성수지층이 일체감 있게 형성되는 것으로서, 발광소자부는 인서트 사출 성형시 고열에 의해 몰드에 주어진 형상으로 변형되어 그 표면은 입체감을 갖게 된다.According to the present invention, a synthetic resin layer having an appropriate thickness is formed on the rear surface of the light emitting device portion, and the light emitting device portion is deformed into a shape given to the mold by high heat during insert injection molding, so that the surface has a three-dimensional appearance.

또한 이때 가해지는 고열 및 고압은 보호층(4)(12)을 통하여 형광층(8) 내지는 도전층(6)(11)에 전달되고, 또 도전층(6)(11)은 분말화된 도전물질과 합성수지를 혼합 구성하므로서, 도전성을 띄면서도 타층과의 박리우려 없이 각층이 갖는 합성수지로 인하여 일체감있게 성형될 수가 있어 도전층(6)(11)과 형광층(8)이 보호되므로 사출성형 과정에서 발광소자부가 손상될 우려가 전혀 없게 된다.At this time, the high temperature and the high pressure applied are transferred to the fluorescent layer 8 or the conductive layer 6 and 11 through the protective layers 4 and 12, and the conductive layers 6 and 11 are powdered conductive.
