Preparation method of corrosion-resistant baffle surface coating for TFT (thin film transistor) process and coating
The invention discloses a preparation method of a corrosion-resistant baffle surface coating for a TFT (Thin Film Transistor) process, which comprises the following steps: (1) powder preparation: (1) taking a composite ceramic powder raw material, and mixing to form slurry; (2) adding a binder into the slurry formed in the step (1), and mixing to form granulation slurry; (3) carrying out spray granulation on the granulation slurry formed in the step (2) in a spray granulator to form basically spherical composite ceramic spray particles; (2) pretreatment: carrying out pretreatment on the baffle element base body; and (3) plasma spraying: performing plasma spraying on the composite ceramic spray particles to form a composite ceramic layer. According to the invention, the defects of black spots, short circuit and the like of the TFT film are reduced, and the display quality of LED and OLED displays is improved.
本申请公开了一种一种TFT工艺用耐腐蚀挡板表面涂层的制备方法，包括以下步骤：⑴粉末制备：①取复合陶瓷粉体原料，混合形成浆料；②在①形成的浆料中加入粘结剂，混合形成造粒浆料；③将②形成的造粒浆料在喷雾造粒机中喷雾造粒形成基本为球形的复合陶瓷喷雾粒子；⑵前处理：对挡板元件基体前处理；⑶等离子喷涂：等离子喷涂复合陶瓷喷雾粒子形成复合陶瓷层。本申请降低了TFT薄膜黑点、短路等缺陷，提高了LED、OLED显示器的显示质量。
