[0018] In specific implementation, the electronic paper frame sealing structure is an encapsulation structure of the edge of the electronic paper display screen, mainly used for protecting the internal components of the electronic paper main body 3. Most of the traditional sealing glue is a thermosetting system, which has high requirements for curing temperature and time, so that the sealing performance of the electronic paper frame is not high enough. When assembling the electronic paper screen, first place the electronic paper main body 3 on the surface of the TFT glass bottom plate main body 1. At this time, UV curing glue 10 can be used to coat between the four surrounding frames of the electronic paper main body 3 and the surface of the TFT glass bottom plate main body 1.
