CONSTITUTION: The image display element comprises: a first glass substrate(211); a touch panel(200) apart by a predetermined distance, facing the first glass substrate; a liquid crystal layer(212) interposed between an inner surface of the first glass substrate and an inner surface of the touch panel; a polarizing film(213, 213') attached on an outer surface of the first glass substrate and an outer surface of the touch panel. Thus, the first glass substrate is shared by a LCD(210) and a touch panel(200), thereby decreasing the thickness of the image display element and enhancing the transmitivity and the brightness.

Description

화상 표시 소자Image display element

본 발명은 휴대용 단말기의 화상 표시소자에 관한 것으로서, 보다 상세하게는 터치패널(Touch Panel)의 유리기판(Glass)과 액정표시소자(Liquid Crystal Display : 이하 LCD라 지칭함)의 유리기판을 공유하여 터치패널과 액정표시소자를 일체형으로 사용하는 화상 표시 소자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device of a portable terminal, and more particularly, to touch by sharing a glass substrate of a touch panel and a glass substrate of a liquid crystal display (LCD). An image display device using a panel and a liquid crystal display device as one body.

도 1은 종래의 화상 표시 소자의 단면도이다.1 is a cross-sectional view of a conventional image display element.

종래의 화상 표시 소자에서 터치패널(100)은 필름(101)과 유리기판(102)사이에 전류를 공급하기 위한 투명전극(ITO : Indium Tin Oxide)(103)이 부착되어 있다. LCD(100)는 유리기판(112,112')의 대향면에 액정(113)이 주입되어 있다. 유리기판(112,112')의 외면에는 편광판(111, 111')이 부착되어 있다. 또한 이와 같이 구성된 LCD(110)와 터치패널(100)은 양면 테이프(120)에 의해 연결되어 있다. 즉, 터치패널(100)의 유리기판(102) 외면과 LCD(110)의 상부 편향판(111') 외면을 양면 테이프(120)로 연결하여 사용한다. 여기서 터치패널(100)은 LCD(110) 위에 위치시킨다.In the conventional image display device, the touch panel 100 has a transparent electrode (ITO: Indium Tin Oxide) 103 for supplying a current between the film 101 and the glass substrate 102. In the LCD 100, liquid crystals 113 are injected to opposite surfaces of the glass substrates 112 and 112 ′. Polarizers 111 and 111 'are attached to the outer surfaces of the glass substrates 112 and 112'. In addition, the LCD 110 and the touch panel 100 configured as described above are connected by the double-sided tape 120. That is, the outer surface of the glass substrate 102 of the touch panel 100 and the outer surface of the upper deflection plate 111 ′ of the LCD 110 are connected to each other by a double-sided tape 120. The touch panel 100 is positioned on the LCD 110.

이와 같이 종래에는 LCD와 터치패널을 각각 제조한 후에 양면 테이프로 연결시켰기 때문에 두께가 두껍고, 무거우며, 각각의 조립 공정과 LCD, 터치패널을 연결하는 공정이 추가로 있어야 하므로 가격이 높아지고 관리 및 수송비용이 많이 사용되는 문제점이 있었다.Since the LCD and the touch panel are manufactured in the related art, they are thick and heavy because they are connected by double-sided tape. Therefore, each assembly process and the process of connecting the LCD and the touch panel must be additionally performed, resulting in high price and management and transportation. There was a problem that costly use.

도 2는 본 발명에 따른 화상 표시 소자의 단면도이다.2 is a cross-sectional view of an image display element according to the present invention.

도 2에 도시된 소자는 제1 유리기판(211), 제1 유리기판(211)과 소정 간격으로 이격되어 서로 대향되도록 형성된 터치패널(200), 제1 유리기판(211)의 내면 및 터치패널(200)의 내면 사이에 밀봉된 액정층(212), 터치패널(200)의 외면과 제1 유리기판(211)의 외면에 각각 접착된 편향판(213,213')으로 구성된다. 본 발명에서 터치패널(200)은 액정층(212)과 접착된 제2 유리기판(201), 편항판(213')과 접착된 필름(202), 제2 유리기판(201)과 필름(202) 사이에 형성된 투명전극(203)으로 구성된다.The device shown in FIG. 2 is a touch panel 200 formed to be spaced apart from the first glass substrate 211 and the first glass substrate 211 so as to face each other, and the inner surface and the touch panel of the first glass substrate 211. The liquid crystal layer 212 sealed between the inner surfaces of the 200, and the deflection plates 213 and 213 ′ bonded to the outer surface of the touch panel 200 and the outer surface of the first glass substrate 211, respectively. In the present invention, the touch panel 200 includes a second glass substrate 201 adhered to the liquid crystal layer 212, a film 202 adhered to the deflection plate 213 ′, a second glass substrate 201 and a film 202. And a transparent electrode 203 formed therebetween.

이어서, 도 2를 참조하여 본 발명을 상세히 설명하면 다음과 같다.Next, the present invention will be described in detail with reference to FIG. 2.

터치패널(200)은 사용자가 정보를 표현하고 있는 화면에서 손가락으로 원하는 정보를 선택하여 컴퓨터(미도시)에 선택 정보를 입력할 수 있도록 화면에 붙어있는 얇은 판을 의미한다. 이러한 판에서는 손가락의 접촉을 감지하여 손가락에서 접촉된 위치를 좌표로 변환하여 컴퓨터에 전달한다.The touch panel 200 refers to a thin plate attached to a screen so that a user may select desired information with a finger on a screen representing information and input selection information into a computer (not shown). In these plates, the touch of the finger is detected and the position of the finger is converted into coordinates and transmitted to the computer.

LCD(210)는 액체와 고체의 중간 상태인 액정(Liquid Crystal)이라는 물질을 이용하여 전압과 온도의 변화에 따라 빛을 투과 또는 차단시켜 명암을 제어함으로써 원하는 형상을 표시하는 소자이다.The LCD 210 displays a desired shape by controlling the contrast by transmitting or blocking light according to a change in voltage and temperature using a material called liquid crystal, which is an intermediate state between a liquid and a solid.

본 발명의 화상 소자에서는 터치패널(200)을 먼저 제작하고 LCD(210)의 공정에 투입하여 제작하는 것을 기본으로 한다. 이때에도 선별이나 세척 등의 겹처지는 공정들을 줄일 수 있게 된다.In the image device of the present invention, the touch panel 200 is first manufactured and then manufactured by inputting it into the process of the LCD 210. In this case, the overlapping processes such as sorting and washing can be reduced.

터치패널(200)은 제1 유리기판(211)과 소정 간격으로 이격되어 서로 대향되도록 형성되어 있다. 터치패널(200)은 전극판을 형성하기 위해서 제2 유리기판(201)과 투명한 필름(202) 사이에 투명전극(203)이 형성되어 있다. 제1 유리기판(211)의 내면 및 터치패널(200)의 제2 유리기판(201) 내면 사이에 액정층(212)이 밀봉되어 있다. 제1 유리기판(211)의 외면과 터치패널(200) 필름(202)의 외면에는 각각 편향판(213,213')이 형성되어 있다.The touch panel 200 is spaced apart from the first glass substrate 211 at predetermined intervals to face each other. In the touch panel 200, a transparent electrode 203 is formed between the second glass substrate 201 and the transparent film 202 to form an electrode plate. The liquid crystal layer 212 is sealed between the inner surface of the first glass substrate 211 and the inner surface of the second glass substrate 201 of the touch panel 200. Deflection plates 213 and 213 'are formed on the outer surface of the first glass substrate 211 and the outer surface of the film 202 of the touch panel 200, respectively.

제1 유리기판(211)은 터치패널(200)과 LCD(210)에서 공유하며, 이 공유되는 제1 유리기판(211)의 투명전극막 처리는 단면에서 양면으로 변경된다. 따라서 제조 공정 시에 양면 산화전극 유리기판 선별, 세정, IR/UV Cleaning 공정은 중첩되기 때문에 줄일 수 있게 된다. 이로인하여 화상 표시 소자의 두께가 얇아져서 터치패널(200)의 투과율을 향상시켜 LCD(210) 화면의 밝기를 높일 수 있게 된다.The first glass substrate 211 is shared by the touch panel 200 and the LCD 210, and the transparent electrode film treatment of the shared first glass substrate 211 is changed from one side to both sides. Therefore, in the manufacturing process, the double-sided anode glass substrate sorting, cleaning, and IR / UV cleaning processes can be reduced because they overlap. As a result, the thickness of the image display device is reduced, thereby improving the transmittance of the touch panel 200, thereby increasing the brightness of the LCD 210 screen.

본 발명은 상술한 실시 예에 한정되지 않으며 본 발명의 사상 내에서 당업자에 의한 변형이 가능함은 물론이다.The present invention is not limited to the above-described embodiments and can be modified by those skilled in the art within the spirit of the invention.

상술한 바와 같이 본 발명에 따르면, 유리기판 1개와 양면 테이프의 두께, 게 및 고정을 줄일 수 있기 때문에 이로 인한 가격, 관리 및 수송을 편리하게 할 수 있고 터치 패널의 투과율을 향상시켜 LCD 화면의 밝기를 높일 수 있는 효과가 있다.As described above, according to the present invention, since the thickness, crab, and fixing of one glass substrate and double-sided tape can be reduced, the cost, management, and transportation thereof can be convenient, and the transmittance of the touch panel can be improved to improve the brightness of the LCD screen. There is an effect to increase.
