Description

Technical Field

[0001] This utility model relates to the field of electronic paper technology, specifically to an electronic paper screen module with high impact resistance. Background Technology

[0002] An electronic paper module (EPM) is a display module based on electronic ink (E Ink) or other similar technologies that simulates the appearance and reading experience of traditional paper. Its core features are bistable and reflective display. Its main components include a substrate, a TFT backplane, and an electronic ink layer. During operation, only the substrate protects the TFT backplane and electronic ink layer. Its edges are easily damaged by external impacts, resulting in a low safety factor. Furthermore, the contact between the TFT backplane and the electronic ink layer can also transmit external forces, causing damage to the electronic ink layer and leading to a relatively short lifespan for existing electronic paper modules. Utility Model Content

At the same time, an insulating layer is used to insulate the electronic paper screen module, which can further reduce the interference of external factors on the electronic paper screen module and extend its service life.

[0006] Preferably, a receiving groove is provided in the middle of the back side of the shock-absorbing layer for the TFT backplate layer and the insulating layer to be inserted. An opening is provided on the inner wall of the receiving groove near the panel layer for the electronic paper layer to be attached to the panel layer. The electronic paper layer is attached to the back side of the panel layer through the opening. The back side of the electronic paper layer is flush with the inner wall of the receiving groove near the panel layer. The edge of the front side of the TFT backplate layer abuts against the inner wall of the receiving groove near the panel layer.

[0007] Preferably, the back side of the insulating layer is flush with the back side of the shock-absorbing layer.

[0008] Preferably, the back edge of the damping layer is chamfered.
