Abstract

An electronic apparatus. The electronic apparatus includes a flexible display panel and a support for supporting the flexible display panel. The flexible display panel has a display area and a peripheral area, and an edge groove in the peripheral area defining an edge portion of the flexible display panel. The edge portion being on a side of the edge groove distal to the display area. The support has a first support groove configured to receive the edge portion of the flexible display panel. The flexible display panel is bent about the edge groove, facilitating insertion of the edge portion of the flexible display panel into the first support groove.

the flexible display panel is bent about the edge groove;
wherein an edge portion of the cover glass is inserted into the second support groove.

2. The electronic apparatus of claim 1 , wherein the barrier extends away from the bottoms of the first support groove and the second support groove along a direction substantially perpendicular to the bottoms of the first support groove and the second support groove.

3. The electronic apparatus of claim 1 , wherein the first support groove and the second support groove are directly adjacent to each other.

4. The electronic apparatus of claim 1 , wherein the first support groove has a first side wall and a second side wall facing each other, and a third side wall connecting the first side wall and the second side wall;
the second support groove has a fourth side wall and a sixth side wall, and a fifth side wall connecting the fourth side wall and the sixth side wall;
the barrier extends away from the third side wall and the fifth side wall; and
the first side wall and the sixth side wall are two opposite side walls of the barrier.

5. The electronic apparatus of claim 4 , wherein the edge groove substantially surrounds the display area.

6. The electronic apparatus of claim 4 , wherein the second side wall of the first support groove has a curved surface; and
the edge portion of the flexible display panel curves about the curved surface of the second side wall, and in direct contact with the curved surface.

7. The electronic apparatus of claim 1 , wherein the edge groove is disposed on two opposing sides of the flexible display panel.

8. The electronic apparatus of claim 1 , wherein the edge groove comprises a plurality rows of sub-edge grooves each having a plurality of sub-edge grooves; and
any individual one of the plurality of sub-edge grooves in one row of the plurality rows of sub-edge grooves is misaligned with respect to the plurality of sub-edge grooves in an adjacent row of the plurality rows of sub-edge grooves.

9. The electronic apparatus of claim 8 , wherein any individual one of the plurality of sub-edge grooves in one row of the plurality rows of sub-edge grooves is aligned with a space between adjacent sub-edge grooves of the plurality of sub-edge grooves in an adjacent row of the plurality rows of sub-edge grooves.

10. The electronic apparatus of claim 1 , wherein the first support groove is curved along its depth direction; and
the edge portion of the flexible display panel is curved along a depth direction of the first support groove.

11. The electronic apparatus of claim 1 , wherein the flexible display panel further comprises a flexible material filled in the edge groove.

12. The electronic apparatus of claim 1 , the flexible display panel is a flexible organic light-emitting diode (OLED) display panel.

13. The electronic apparatus of claim 12 , the flexible organic light-emitting diode (OLED) display panel comprises a flexible base substrate and a plurality of functional layers disposed on the flexible base substrate;
wherein the edge groove extends through the plurality of functional layers of the flexible display panel, exposing a surface of the flexible base substrate.

14. The electronic apparatus of claim 1 , wherein the electronic apparatus is a mobile phone;
the support is a middle frame of the mobile phone; and
the electronic apparatus further comprises a back cover.

15. A support for supporting a flexible display panel in an electronic apparatus, comprising:
a first support groove;
a second support groove adjacent to the first support groove, and on a side of the first support groove distal to a central area of the support; and
a barrier extending away from bottoms of the first support groove and the second support groove, separating at least a portion of the first support groove and at least a portion of the second support groove;
wherein the first support groove receives an edge portion of a flexible display panel having an edge groove in a peripheral area defining the edge portion, the edge portion being on a side of the edge groove distal to a display area of the flexible display panel;
the second support groove is receives an edge portion of a cover.

16. The support in the electronic apparatus of claim 15 , wherein the first support groove and the second support groove are directly adjacent to each other;
wherein the first support groove has a first side wall and a second side wall facing each other, and a third side wall connecting the first side wall and the second side wall; and
the second support groove has a fourth side wall and a sixth side wall, and a fifth side wall connecting the fourth side wall and the sixth side wall;
the barrier extends away from the third side wall and the fifth side wall; and
the first side wall and the sixth side wall are two opposite side walls of the barrier.

17. The support in the electronic apparatus of claim 16 , wherein the second side wall of the first support groove has a curved surface.

18. The support in the electronic apparatus of claim 15 , wherein the first support groove having a curved shape along its depth direction.

19. A method of fabricating an electronic apparatus, comprising:
forming a flexible display panel having a display area and a peripheral area;
forming a support for supporting the flexible display panel;
assembling the flexible display panel and the support together; and
providing a cover glass;
