Patent number: 9348159Abstract: An ejection head for ejecting alignment film forming composition includes multiple nozzles. Each nozzle includes a chamber, a composition source, and a control valve. A liquid transportation pipe and a pusher are disposed on the bottom and the top of the chamber, respectively. The pusher is used for pushing the alignment film forming composition out of the liquid transportation pipe. The composition source is used for transporting the alignment film forming composition to the chamber. The control valve is used for controlling switching of the liquid transportation pipe to control output of the alignment film forming composition. Owing to the control valve and the blowing device, the alignment film forming composition is prevented from condensing on the nozzle and blocking the nozzle or from forming large droplets because of accumulation. In this way, the quality of the alignment film is greatly enhanced owing to uniform spraying and regular output.Type: GrantFiled: June 20, 2013Date of Patent: May 24, 2016Assignee: Shenzhen China Star Optoelectronics Technology Co., LtdInventors: Ming Liu, Tao Song, Tao Ma, Guodong Zhao
