LCDスクリーンの製造プロセスは何ですか：
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）ガラス基板を金属膜でコーティングするには、金属材料を真空チャンバー内に配置する必要があります。金属上の特殊ガスがプラズマを生成した後、金属上の原子がガラスにぶつかり、次に層の層が形成されます。 金属フィルムも。
3）金属膜をめっきした後、非-導電層と半-導電層もめっきする必要があります。 真空チャンバー内では、まずガラス板を加熱し、次に高電圧噴霧器で特殊ガスを噴霧して電子とガスプラズマを発生させ、化学反応後、非{{ 4}}ガラス上に導電層と半導体層を形成します。
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）フォトレジストの成形後、不要な膜を露光するためのエッチングによるウェットエッチング、またはプラズマの化学反応によるドライエッチングを行うことができます。 エッチング後、残ったフォトレジストを液体で除去し、最後にトランジスタに必要な回路パターンを生成します。
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）薄膜トランジスタガラス基板を仕上げた後、液晶パネルの組み合わせに進みます。 液晶パネルは、トランジスタガラス基板とカラーフィルタで構成されています。 まず、先に進む前にガラスをきれいにする必要があります。 ワンステップ。 ディスプレイに不純物が入らないように、TFT-LCDの製造プロセス全体をクリーンルームで行う必要があります。
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）フレームを密閉した後、LCDパネルを真空チャンバーに入れ、予約した隙間からLCDパネルから空気を排出し、大気圧を利用して液晶を注ぎ、隙間を閉じます。 液晶は一種の固体と液体の複合物質で、分子が規則正しく配列しているという特徴があります。
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.
