본 발명은 폴리머를 이용한 플랙서블 기판의 셀프-어셈블리 방법에 관한 것 으로서, 더욱 상세하게는 플렉서블 액정디스플레이 제작을 위해 반도체 공정 기술인 사진식각 방법과 탄성 중합체인 폴리머를 이용하여 픽셀 단위로 폴리머-격벽(polymer-isolation wall) 제작 및 제 1 플렉서블 기판과 제 2 플렉서블 기판의 접합을 통해 각각의 픽셀마다 액정의 균일한 셀 갭을 유지함으로써 안정된 플렉서블 액정디스플레이의 구동을 위한 셀프-어셈블리 제작 공정에 관한 것이다.The present invention relates to a self-assembly method of a flexible substrate using a polymer, and more particularly, to fabricating a flexible liquid crystal display. The present invention relates to a self-assembly fabrication process for driving a stable flexible liquid crystal display by maintaining a uniform cell gap of a liquid crystal for each pixel through fabrication of a polymer-isolation wall and bonding a first flexible substrate and a second flexible substrate.
일반적으로 플렉서블 액정디스플레이 어셈블리 공정 시 셀 갭을 유지하기 위해 마이크로-스패이서를 사용하거나 최근에는 UV-엑폭시를 이용하고 있다.In general, in order to maintain a cell gap in a flexible liquid crystal display assembly process, a micro-spacer or a recent UV-epoxy is used.
기존의 평판패널에 사용되는 마이크로-스패이서는 지름이 수 um의 볼을 사용하는 방법으로 패널의 상판과 하판의 일정한 셀 갭을 유지하는데 사용하고 있다.Micro-spacers used in conventional flat panels are used to maintain a constant cell gap between the top and bottom of the panel by using a ball of several um in diameter.
그리고 UV-엑폭시 방식은 액정 주입과 함께 UV-에폭시를 주입하여 UV-노광하여 소성시킴으로써 플렉서블 기판의 셀 갭을 유지하는 기술 등을 들 수 있다.The UV-epoxy method may include a technique of maintaining a cell gap of the flexible substrate by injecting UV-epoxy together with liquid crystal injection and UV-exposure to bake.
최근에는 폴리머의 소성 특성을 이용하여 마스터 몰더를 제작 후 폴리머를 형틀에 부어 고형화한 후, 이를 필-오프 (peel-off) 하는 방식을 사용하여 플렉서블 액정디스플레이의 픽셀패턴 및 픽셀 단위의 격벽(isolation wall)으로 사용되고 있다. 이는 격벽의 폭과 높이를 수 um까지 조절할 수 있으며, 폴리머의 특성으로 외부의 물리적 힘에 따라 탄성의 성질을 갖고 있어 휘어짐에 따라 깨지지 않고 일정한 셀 갭을 유지할 수 있다.Recently, after manufacturing the master mold using the plasticity characteristics of the polymer, the polymer is poured into the mold and solidified, and then peeled off to form a pixel pattern of the flexible liquid crystal display and an isolation of pixel units. It is used as a wall). It can control the width and height of the partition wall up to a few um, it has the property of elasticity according to the external physical force due to the characteristics of the polymer can maintain a constant cell gap without breaking as it is bent.
위의 방법들을 통하여 제작된 플렉서블 액정디스플레이 소자로 제작되기 위해서는 외부 물리적인 힘에 의해 플렉서블 기판이 휘어짐에도 일정한 셀 갭을 유지해야 하며, 전기화학적으로 안정해야 하며, 깨지거나 찢어지지 않아야 한다.In order to manufacture the flexible liquid crystal display device manufactured through the above methods, the flexible substrate should be kept constant even when the flexible substrate is bent by external physical force, and should be electrochemically stable and not be broken or torn.
그러나, 상기 방식들을 통해 생성된 스패이서는 통상 액정의 유실을 막기 위하여 제 1 플레서블 기판과 제 2 플렉서블 기판에 별도의 접합 및 실링(sealing) 공정이 필요하며, 이는 공정상의 절차가 복잡하고 UV-에폭시와 같은 외부 빛에 민감한 특성을 지닌 재료를 액정과 함께 주입하여 제작함으로써 플렉서블 액정디스플레이의 동작 신뢰성을 기대하기 어렵다.However, spacers generated through the above methods generally require separate bonding and sealing processes on the first flexible substrate and the second flexible substrate to prevent the loss of liquid crystal, which is complicated in process and UV. -It is difficult to expect the operation reliability of the flexible liquid crystal display by injecting a material with sensitive properties to external light such as epoxy together with the liquid crystal.
본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 별도의 에폭시나 스패이서 없이 기존의 반도체 공정기술인 사진식각 공정으로 폴리머를 이용하여 픽셀 단위의 스패이서 기둥을 형성함과 동시에 폴리머의 소성 특성을 이용하여 상부 기판과 하부 기판의 접합을 유도함으로써 셀프-어셈블리 하는 제조방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the above points, and forms a spacer column of pixel units using a polymer in a photolithography process, which is a conventional semiconductor process technology without a separate epoxy or a spacer, and at the same time improves the plasticity characteristics of the polymer. It is an object of the present invention to provide a fabrication method of self-assembly by inducing bonding of an upper substrate and a lower substrate by using the same.
