Abstract
본 발명은 디스플레이 패널 이송용 타이밍벨트에 관한 것으로, 본체부(10); 및 상기 본체부(10) 위에 적층되며 디스플레이 패널과 접촉하는 접촉부(20); 을 포함하되, 상기 접촉부(20)는, 상기 본체부(10)와 접촉되는 기저층(21); 상기 기저층(21) 위에 도포되는 접착층(23); 및 상기 접착층(23) 위에 적층되는 표층(25); 을 포함하는 것을 기술적 특징으로 하며, 디스플레이 패널 이송시 스크래치 발생을 방지할 수 있는 장점이 있으며, 타이밍벨트의 내구성을 향상시킬 수 있는 장점이 있다. The present invention relates to a timing belt for transporting a display panel, comprising: a main body (10); and a contact portion 20 that is stacked on the main body 10 and contacts the display panel. It includes, but the contact portion 20 includes: a base layer 21 in contact with the main body portion 10; an adhesive layer (23) applied on the base layer (21); and a surface layer (25) laminated on the adhesive layer (23); Its technical features include the advantage of preventing scratches when transporting the display panel and the advantage of improving the durability of the timing belt.
Description
본 발명은 디스플레이 패널 이송용 타이밍벨트에 관한 것으로, 보다 상세하게는 디스플레이 패널 이송시 스크래치 발생을 방지할 수 있으며, 타이밍벨트의 내구성을 향상시킬 수 있는, 디스플레이 패널 이송용 타이밍벨트에 관한 것이다.The present invention relates to a timing belt for transporting a display panel, and more specifically, to a timing belt for transporting a display panel, which can prevent scratches when transporting a display panel and improve the durability of the timing belt.
최근 본격적인 정보화 시대에 발맞추어 각종 전기적 신호에 의한 대용량의 데이터를 시각적 화상으로 표시하는 디스플레이(display) 분야 또한 급속도로 발전하였고, 이에 부응하여 경량화, 박형화, 저소비전력화 장점을 지닌 평판표시장치(Flat Panel Display device : FPD)로서, 액정표시장치(Liquid Crystal Display device: LCD), 플라즈마표시장치(Plasma Display Panel device: PDP), 전계방출표시장치(Field Emission Display device: FED), 전기발광표시장치(Electro luminescence Display device : ELD) 등이 소개되어 기존의 브라운관(Cathode Ray Tube : CRT)을 빠르게 대체하고 있다.Recently, in line with the full-fledged information age, the display field, which displays large amounts of data through various electrical signals as visual images, has also developed rapidly, and in response to this, flat panel displays have the advantages of being lightweight, thin, and low power consumption. Display device: FPD, Liquid Crystal Display device (LCD), Plasma Display Panel device (PDP), Field Emission Display device (FED), Electroluminescent display device (Electro) Luminescence Display Device (ELD) has been introduced and is rapidly replacing the existing cathode ray tube (CRT).
