Curved display module and display device
The invention discloses a curved display module and a display device. The curved display module includes an enclosure, at least one opening, a flexible display panel and an Optical Clear Adhesive (OCA) layer. There is a first curved surface inside the enclosure. A cavity is formed within the enclosure. The at least one opening are disposed on at least one edge of the enclosure and connected to the cavity. The flexible display panel is disposed on the first curved surface in the cavity. The OCA layer is disposed within the cavity. The OCA layer directly covers the flexible display panel.
1. A display device, comprising:
a main case having a first curved surface, the first curved surface having a covered region and two opposite exposed regions connected to opposite sides of the covered region;
an electronic system disposed within the main case; and
a curved display module disposed on the main case, the curved display module comprising:
an enclosure disposed on the first curved surface, wherein the covered region is covered by the enclosure, and the exposed regions are not covered by the enclosure, wherein the enclosure comprises an outer curved surface and two opposite outer flat surfaces connected to opposite sides of the outer curved surface, wherein a cavity is formed between the enclosure and the covered region of the first curved surface of the main case;
a flexible display panel disposed in the cavity, and a portion of the flexible display panel being in contact with the covered region of the first curved surface of the main case;
an optical clear adhesive layer disposed within the cavity, the optical clear adhesive layer directly covering another portion of the flexible display panel that is not in contact with the covered region; and
three openings, each having a closed-boundary, configured to inject the optical clear adhesive layer into the cavity, wherein two of the three openings are formed on one of the two outer flat surfaces, and the other one of the three openings is formed on another one of the two outer flat surfaces, wherein the exposed regions of the first curved surface of the main case extends from outer edges of the outer flat surfaces upwardly, and the outer curved surface extends from inner edges of the outer flat surfaces downwardly;
wherein a cross section of the covered region of the main case is arc-shaped and has a height, and the two exposed regions of the main case extend from the opposite sides of the covered region and are substantially parallel to the height of the covered region;
wherein the main case further has two top flat surfaces connected respectively to upper ends of the exposed regions of the main case, and the two top flat surfaces are substantially perpendicular to the height of the covered region;
wherein a cross section of the outer curved surface of the enclosure is arc-shaped and has a height, the two opposite outer flat surfaces of the enclosure extend respectively from the opposite sides of the outer curved surface and are substantially perpendicular to the height of the outer curved surface, and areas of the outer curved surface adjacent to the connection with the two opposite outer flat surfaces are formed as vertical sections that are substantially parallel to the height of the outer curved surface;
wherein the heights of the covered region of the main case and the outer curved surface of the enclosure are taken along lines that are roughly coincident with a line that interconnects a center point of the covered region of the main case with a center point of the outer curved surface of the enclosure;
wherein when the display device is placed on a flat supporting surface with the flexible display panel facing upwardly, the covered region of the main case and the outer curved surface of the enclosure arc upwardly and their heights are substantially perpendicular to the supporting surface, a stepped configuration is formed on each side of the display device when the display device is viewed in cross section, and the stepped configuration on each side of the display device includes a pair of downwardly descending steps formed by one of the top flat surfaces of the main case, the corresponding exposed region of the main case, the corresponding outer flat surface of the enclosure, and the corresponding vertical section of the outer curved surface of the enclosure in this sequence.
2. The display device of claim 1 , wherein a second curved surface is formed inside the enclosure, the second curved surface of the enclosure is opposite to the first curved surface of the main case, the cavity is formed between the first curved surface and the second curved surface, and the optical clear adhesive layer is disposed between the flexible display panel and the second curved surface.
3. The display device of claim 1 , wherein at least a part of the enclosure is transparent.
4. The display device of claim 1 , wherein the optical clear adhesive layer is formed by injecting a liquid optical clear adhesive through the at least one opening into the cavity.
5. The display device of claim 1 , wherein the optical clear adhesive layer is transformed from a liquid optical clear adhesive injected into the cavity through any one of the three openings.
6. The display device of claim 1 , wherein the optical clear adhesive layer is made by at least one material selected from the group consisting of silicone, acrylic plastic, resin and epoxy resin.
