Description

Technical Field

[0001] The utility model relates to the technical field of display screen production, in particular to a film coating device for producing a flexible display screen. Background Art

[0002] Flexible displays use PHOLED phosphorescent OLED technology, have low power consumption, directly visible flexible panels, are made of soft materials, and are deformable and bendable display devices. Flexible displays are extremely light and thin and deformable. As completely different devices, they can be used for completely different purposes. Due to the bendable nature of flexible displays, traditional protective films can no longer meet the needs of flexible displays. The coating attached to its surface must be flexible and will not break when folded. Only in this way can it change with the bending of the flexible display. At present, most of the coatings on flexible displays are sprayed. The coating paint is dissolved with a solvent and then sprayed on the surface of the flexible display. The solvent evaporates to leave a coating structure on the surface of the flexible display.

[0003] However, when the existing laminating device uses a spray coating method for laminating, excess laminating paint may drip from the display screen, causing pollution to the environment around the device. Therefore, it is necessary to propose a laminating device for the production of flexible display screens. Utility Model Content
