Description

Technical Field

[0001] The present application relates to the technical field of display screens, and in particular to a display screen with a curved structure. Background Art

[0002] With the development of electronic technology, electronic devices are widely used in all aspects of people's life, work and study. At the same time, the display screens of electronic devices are also popular among the public due to their easy operation and beautiful appearance.

[0003] The in-vehicle display screen devices used in the automotive field are usually a flat plate structure, but this shape structure of the display screen device can no longer satisfy people's sensory experience. The industry has currently proposed a curved structure display screen. The so-called curved structure display screen still designs the original display screen as a flat plate structure, but designs the glass cover plate on the display screen into a curved structure, that is, using a curved glass cover plate, to bring users a different visual experience.

[0004] In order to achieve the effect of an integrated black surface, the curved structure display screen in the existing technology often adopts the method of silk screen printing followed by inkjet printing. That is, silk screen printing is used for the flat convex parts, and inkjet printing is used for the uneven sunken parts. However, the ink on the sprayed parts will be particularly thick, resulting in a large ink step difference after the display screen is bonded with solid glue. The visual experience of the entire curved structure display screen is poor and the yield rate is low. Utility Model Content

[0005] In order to address the deficiencies in the prior art, the present application aims to provide a display screen with a curved structure that can avoid ink step differences and improve the viewing experience.

[0006] To achieve the above-mentioned objectives, the present application provides a display screen with a curved structure, including a curved cover plate, the curved cover plate including a curved surface and a flat surface arranged opposite to each other, a placement groove being provided on the flat surface, a first ink layer being silk-screened on the bottom surface of the placement groove corresponding to an area outside the visible area of ​​the display screen, a second ink layer being sprayed on the side surface of the placement groove, a portion of the second ink layer close to the bottom surface of the placement groove extending inward to cover a portion of the first ink layer, and a display screen body being provided in the placement groove by liquid glue.

[0007] As a further optimization method of the curved display screen provided by the present invention, a flat glass cover plate is adhered above the liquid glue, and the display screen body is adhered to the flat glass cover plate by solid glue.

[0008] As a further optimization method of the curved display screen provided by the present invention, the thickness of the liquid glue is 0.25 to 0.35 mm.

[0009] As a further optimization method of the curved display screen provided by the present invention, the thickness of the flat glass cover plate is 0.45 to 0.55 mm.

[0010] As a further optimization method of the curved display screen provided by the present invention, the thickness of the solid glue is 0.1 to 0.2 mm.

[0011] As a further optimization method of the display screen with a curved surface structure provided by the present invention, PET double-sided tape is further adhered on the plane.

[0012] As a further optimization method of the display screen with a curved surface structure provided by the present invention, a through hole is further provided on the plane.

[0013] As a further optimization method of the display screen with a curved structure provided by the present invention, two through holes are provided.

[0014] As a further optimization method of the display screen with a curved structure provided by the present invention, the curved cover plate is a PMMA cover plate.

[0015] As a further optimization method of the curved display screen provided by the present invention, the display screen body is an AMOLED display screen.

[0016] The curved display screen of the present application has the following beneficial effects:

[0017] The curved display screen of the present application uses liquid glue to absorb the ink step difference caused by the first ink layer and the second ink layer on the curved cover plate, and then uses the cover plate and solid glue to bond the display screen, avoiding the problem of ink step difference that is easily caused by directly using solid glue to bond the display screen, and has a high yield and good visual experience.

[0018] Other features and advantages of the present application will be set forth in the following description, and in part will be apparent from the description, or may be learned by practicing the present application. BRIEF DESCRIPTION OF THE DRAWINGS
