Flexible displaying apparatus
View Patent ↗A displaying apparatus includes a flexible substrate, at least one composite layer disposed on the flexible substrate, and an electronic device disposed on the composite layer. The composite layer includes a stack of an organic layer and an inorganic layer, and at least one of the inorganic layer and the organic layer includes at least one anti-static material, such as anti-static particles, an anti-static agent or an anti-static layer (e.g., transparent conductive layer/transparent conductive oxide layer, or polymeric conductive layer). The displaying apparatus of the embodiment enables the electronic device, such as the flexible electronic device, to achieve the product requirements, such as the flexibility, good resistance to water and vapor, and the ability of releasing the electrostatic charges and making the overall structure to release stresses.
1. A displaying apparatus, comprising:
a flexible substrate;
at least one composite layer disposed on the flexible substrate, and the at least one composite layer comprising an organic layer and an inorganic layer disposed above the organic layer; and
an electronic device disposed on the at least one composite layer, wherein the organic layer is in contact with the flexible substrate and comprises at least one anti-static material, and the inorganic layer is in contact with the electronic device.
2. The displaying apparatus according to claim 1 , wherein the anti-static material comprises a plurality of anti-static particles or an anti-static agent, mixed within the organic layer.
3. The displaying apparatus according to claim 1 , wherein said anti-static material is a conductive polymer.
4. The displaying apparatus according to claim 3 , wherein the at least one composite layer further comprises an another organic layer.
5. The displaying apparatus according to claim 1 , wherein the inorganic layer comprises an another anti-static material, and said another anti-static material is a transparent conductive material.
6. The displaying apparatus according to claim 5 , wherein the at least one composite layer further comprises an another inorganic layer.
7. The displaying apparatus according to claim 1 , wherein a water vapor transmission rate of the at least one composite layer is less than 5×10 −6 g/m 2 /day.
8. The displaying apparatus according to claim 1 , wherein a weight percentage of the anti-static material to the at least one composite layer ranges from 1 wt % to 10 wt %.
9. The displaying apparatus according to claim 1 , wherein a surface resistivity of the at least one composite layer is less than 10 11 Ω.
10. The displaying apparatus according to claim 1 , wherein a stack of the flexible substrate, the at least one composite layer and the electronic device has a total stress substantially equal to 0.
