Problems solved by technology

[0004] In order to ensure the service life of the OLED display device and protect the OLED device from being eroded by substances such as water and oxygen, it is necessary to reduce the residual air bubbles in the material for making the flexible substrate. If the air bubbles are located at the position of the lead wire, it will also bulge the lead wire, which is easy to cause lead wire damage. Line damage and other problems, the current degassing device does not have a good degassing effect

Abstract

The invention discloses a defoaming system, a defoaming method and a display panel. The system includes: a defoaming device, which is used to remove the bubbles of the solution in the defoaming device; a temperature control device, which includes a temperature control circuit and a circulation circuit, and the temperature control circuit is arranged around the defoaming device to control The temperature of the solution in the degassing device; the circulation loop is connected with the temperature control loop to provide the temperature control medium to the temperature control loop. Through the above method, the present invention can improve the degassing effect of the degassing device.

Description

technical field [0001] The invention relates to the technical field of fluid defoaming, in particular to a defoaming system, a defoaming method and a display panel. Background technique [0002] A flexible display panel is a variable and bendable display device. Flexible display panels can include electronic paper, LCD, OLED, etc. Among them, OLED flexible display panels have the characteristics of low power consumption, low thickness, and rollability, and have attracted widespread attention. [0003] The OLED flexible display panel includes a flexible substrate, an OLED display device, and leads connected to the OLED display device. Wherein, the OLED display device includes an anode and a cathode arranged oppositely, and a functional layer arranged between the anode and the cathode. The light-emitting principle of the OLED display panel is that semiconductor materials and organic light-emitting materials are driven by an electric field between the cathode and the anode, a...
