Flexible display device with multiple types of micro-coating layers
There is provided a flexible display having a plurality of innovations configured to allow bending of a portion or portions to reduce apparent border size and/or utilize the side surface of an assembled flexible display.
1. A flexible organic light-emitting diode (OLED) display apparatus, comprising:
a base layer including two flat portions and a bend allowance section between two flat portions; and
an acrylic based coating layer provided over the bend allowance section and a part of the two flat portions, and including one or more of getter material dispersed therein.
2. The flexible organic light-emitting diode (OLED) display apparatus of claim 1 , further comprising a plurality of wire traces disposed in the bend allowance section, wherein one or more insulation layers on the base layer are absent in a space between two adjacent wire traces.
3. The flexible organic light-emitting diode (OLED) display apparatus of claim 1 , further comprising a plurality of wire traces in the bend allowance section, wherein at least one of the plurality of wire traces includes a first part and a second part separated by a space between the first part and the second part, which is filled with the coating layer.
4. The flexible organic light-emitting diode (OLED) display apparatus of claim 2 , the coating layer includes a first micro-coating layer coated over the plurality of wire traces; and a second micro-coating layer coated over the first micro-coating layer coated over the plurality of wire traces.
5. The flexible organic light-emitting diode (OLED) display apparatus of claim 4 , wherein at least one of the first and second micro-coating layers is formed of a photo-curable material.
6. The flexible organic light-emitting diode (OLED) display apparatus of claim 1 , wherein said one or more getter material includes silica based particles.
7. The flexible organic light-emitting diode (OLED) display apparatus of claim 1 , further comprising an encapsulation in one of the flat portions; wherein the coating layer is coated over at least some parts of the encapsulation.
8. The flexible organic light-emitting diode (OLED) display apparatus of claim 7 , further comprising a printed circuit film attached in the other one of the flat portions; wherein the coating layer is coated over at least some part of the printed circuit film.
9. The flexible organic light-emitting diode (OLED) display apparatus of claim 7 , further comprising a polarization layer on the encapsulation arranged to expose an upper surface of the encapsulation between an edge of polarization layer and an edge of the encapsulation, wherein the coating layer is in contact with the polarization layer.
10. The flexible organic light-emitting diode (OLED) display apparatus of claim 4 , wherein the first micro-coating layer is more flexible than the second micro-coating layer.
11. The flexible organic light-emitting diode (OLED) display apparatus of claim 4 , wherein the second micro-coating layer has a higher adhesive property than the first micro-coating layer.
