Patent number: 11239113Abstract: The present disclosure discloses an array substrate and a preparation method thereof. After a first passivation layer is formed, residual gas is directly drawn out of a closed chamber to prevent the residual gas from reacting to form an unstable layer on the first passivation layer. Furthermore, after the residual gas is drawn out, a preset gas fills the closed chamber, and is retained for a preset time period and then drawn out. The retaining of the preset gas can effectively alleviate the damage to the passivation layer by static electricity.Type: GrantFiled: March 31, 2020Date of Patent: February 1, 2022Assignees: Beijing BOE Optoelectronics Technology Co., Ltd., BOE Technology Group Co., Ltd.Inventors: Wei Chen, Zhiqiang Zhang, Hanqing Liu, Yangheng Li, Mingming Jia, Xin Li, Yong Song
