Problems solved by technology
However, many research results show that the existence of water vapor inside the OLED device is the main factor affecting the life of the OLED.
[0004] In order to block water vapor, OLED display panels need to be packaged. In the traditional packaging process, the glue dispenser can only apply one packaging glue at a time. When multiple glue layers are required, each glue line needs to be formed sequentially. The packaging steps of the glue are independent of each other and implemented in different cavities successively. The cover plates need to be operated independently and transferred to each other in different cavities, which seriously restricts the working efficiency of the packaging process and is not conducive to the reduction of production costs.

The invention discloses a packaging glue dispensing device and a packaging method thereof. The packaging glue dispensing device comprises a machine table, a fixed wall, a movable force arm, a rotary clamp, a packaging glue barrel and a spray head. According to the packaging structure of the display panel, the number of the packaging rubber barrels and the number of the pinholes in the spray head are flexibly set, so that a plurality of rubber lines can be formed at a time in the process that the packaging rubber barrels move to discharge rubber, the packaging process of the display panel can be integrated into one step to be completed, the packaging technological process is simplified, the packaging working efficiency is greatly improved, and the production cost of the display panel can be reduced.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a package dispensing device and a package method thereof. Background technique [0002] Organic Light Emitting Diode (OLED for short) display panels have the characteristics of fast response and thinness, and have been applied to fields such as mobile display devices and television devices. [0003] The service life of OLED devices is an important factor restricting the development of OLED industry. There are many factors that affect the service life of OLED devices, including physical factors, such as device structure, circuit driving mode, etc.; there are also chemical factors, such as oxidation of metal cathodes, crystallization and aging of organic materials, etc. However, many research results show that the existence of water vapor inside the OLED device is the main factor affecting the life of the OLED. [0004] In order to block water vapor, OLED display panels need to ...
