Embodiment 1
[0060] Such as image 3 As shown, a foldable AMOLED display structure includes a PI substrate 1, a circuit driving layer 2, and an OLED layer 3 from bottom to top, and a multi-layer thin film encapsulation layer 4 is arranged above the OLED layer 3, and the multi-layer thin film An ultra-thin glass layer 6 is pasted on the packaging layer, a touch sensor layer 7 is coated on the top of the ultra-thin glass layer 6, a circular polarizer 9 is pasted on the top of the touch sensor layer 7, and PET11, PET11 is pasted on the top of the circular polarizer The upper surface is provided with a hardened antifouling film 12 .
[0061] The circuit driving layer in this embodiment is a TFT made of LTPS, the OLED layer is RGB_OLED, and the TFT and OLED form an AMOLED.
[0062] This embodiment preferably also includes a first optical adhesive layer 5, a second optical adhesive layer 8, and a third optical adhesive layer 10, and the ultra-thin glass layer and the multilayer film packaging l...
Embodiment 2
[0077] Such as Figure 4 As shown, a foldable AMOLED display structure includes a PI substrate 1, a circuit driving layer 2, and an OLED layer 3 from bottom to top, and a multi-layer thin film encapsulation layer 4 is arranged above the OLED layer 3, and the multi-layer thin film A circular polarizer 9 is pasted on the top of the encapsulation layer 4, an ultra-thin glass layer 6 is pasted on the top of the circular polarizer 9, a touch sensor layer 7 is coated on the top of the ultra-thin glass layer 6, and a touch sensor layer 7 is coated on the top of the touch sensor layer 7. Laminated with PET11, the upper surface of the PET is provided with a hardened antifouling film 12.
[0078] In this embodiment, the first optical adhesive layer 5 is used to bond the circular polarizer and the multilayer thin film encapsulation layer; the second optical adhesive layer 8 is used to bond the circular polarizer and the ultra-thin glass layer; the third optical adhesive layer 10 Used fo...
