LCD 화면의 생산 공정은 무엇입니까?
1, array manufacturing process
1) A piece of glass with a smooth surface and no impurities is the most important raw material for making TFT glass substrates. Before production, it is necessary to wash the glass with a special detergent, then dehydrate and spin dry.
2) 유리기판을 금속막으로 코팅하기 위해서는 진공챔버에 금속재료를 넣어야 하며 금속의 특수가스가 플라즈마를 발생시킨 후 금속의 원자가 유리에 부딪혀 층이 형성됩니다. 메탈 필름도.
3) 금속 필름이 도금된 후 비전도층과{1}반도전층도 도금해야 합니다.{2}} 진공 챔버에서 유리판을 먼저 가열한 다음 고압 분무기로 특수 가스를-분사하여 전자와 가스 Plasma를 발생시키고 화학 반응 후 비{{ 4}}도전층 및 반도체층이 유리 상에 형성된다.
LCD
4) After the film is formed, we need to make a pattern of transistors on the glass. First, enter the yellow light room and spray a photoresist with a very strong photosensitive, then put on the photomask to irradiate blue-violet light for exposure, and finally send the developer to the developing area to spray the developer, which can remove the photoresist after the light and let the light The resist layer is shaped.
5) 포토레지스트를 성형한 후, 불필요한 막을 노출시키기 위해 에칭으로 습식 식각을 하거나 플라즈마의 화학 반응으로 건식 식각을 할 수 있다. 식각 후 남은 포토레지스트를 액체로 제거하고 마지막으로 트랜지스터에 필요한 회로 패턴을 생성합니다.
6) To form a usable thin-film transistor, it is necessary to repeat the process of cleaning, coating, photoresist, exposure, development, etching, and photoresist removal. Generally speaking, to manufacture TFT-LCD, it is necessary to repeat 5 to 7 times.
2, assembly process
1) 박막트랜지스터 유리기판을 완성한 후 액정패널 결합을 진행합니다. 액정 패널은 트랜지스터 유리 기판과 컬러 필터로 구성됩니다. 먼저 진행하기 전에 유리를 청소해야 합니다. 한 걸음. TFT{1}}LCD의 전체 제조 공정은 디스플레이에 불순물이 없도록 클린룸에서 이루어져야 합니다.
2) The color filter is a chemical coating method to form red, green, and blue colors on the glass, and then it is completed by covering it with a conductive film.
3) In the entire assembly process, first we have to coat a layer of chemical film on the glass and color filter covered with transistors, and then perform the alignment action.
4) Before combining the two glass plates, we must first evenly cover the spherical-like gaps at a fixed interval to prevent the two glass plates from being curved inward after the liquid crystal panel is combined. Usually, when the liquid crystal panel is assembled, one or two gaps are left to facilitate the subsequent filling of the liquid crystal, and then the edge of the two pieces of glass is sealed with sealant and conductive glue, thus completing the glass assembly.
5) 프레임을 밀봉한 후 LCD 패널을 진공 챔버에 넣고 방금 남겨둔 틈을 통해 LCD 패널의 공기를 배출한 다음 대기압의 도움으로 액정을 부은 다음 틈을 닫습니다. 액정은 고체와 액체 사이의 일종의 복합 물질로 분자 배열이 규칙적인 특성을 가지고 있습니다.
6) Finally, attach two vertical polarizers, and the entire LCD panel is completed.
3, module manufacturing process
1) After the polarizer is attached, we start to mount DRIVE IC on both sides of the LCD panel. DRIVE IC is a very important drive component, which is used to control the color and brightness of the LCD.
2) Then connect the input end of the DRIVE IC to the circuit board by soldering. In this way, the signal can be sent out smoothly, and then the image on the control panel is ready.
3) The light of the LCD panel is emitted from the backlight. Before assembling the backlight, we will first check whether the assembled LCD panel is perfect, and then assemble the backlight. The backlight is the source of light behind the LCD panel.
4) Finally, lock the CELL and the iron frame with screws.
5) When we come back, we will enter the final critical test process. The assembled modules are subjected to aging test, and products with poor quality are screened out in the state of electrification and high temperature.
6) The best quality products can be packaged and shipped.
In this way, the LCD panel has undergone many inspection and testing procedures to deliver the most perfect product to the customer, and this is the real completion of the entire LCD production process.
