[0036] Figure 1 is a schematic structural diagram of the display screen of the embodiment of the present application. The following will be combined with Figure 1 , and the display screen structure of the embodiment of the present application will be described in detail.
[0037] The display screen of the embodiment of the present application includes: a film layer 101.
[0038] In some exemplary embodiments, the film layer 101 includes a film substrate.
[0039] In some exemplary embodiments, the display screen of the embodiment of the present application further includes: an OCA optical adhesive layer 102.
[0040] In some exemplary embodiments, the OCA optical adhesive layer 102 includes OCA optical adhesive.
[0041] In some exemplary embodiments, OCA (Optically Clear Adhesive).
[0042] In some exemplary embodiments, the OCA optical adhesive is a double-sided bonding tape without a matrix material.
[0043] In some exemplary embodiments, the OCA optical adhesive has the advantages of clarity, high light transmittance (total light transmittance > 99%), high adhesion, high weather resistance, water resistance, high temperature resistance, ultraviolet resistance, controlled thickness, providing uniform spacing, and will not turn yellow (yellowing), peel off or deteriorate after long-term use.
[0044] In some exemplary embodiments, the OCA optical adhesive layer 102 is disposed on the film layer 101.
[0045] In some exemplary embodiments, the thickness of the OCA optical adhesive layer 102 is 100 - 150 um.
[0046] In some exemplary embodiments, the OCA optical adhesive layer 102 is provided with a plurality of pinholes 104, and the pinholes 104 are small holes penetrating through the OCA optical adhesive layer 102.
[0047] In some exemplary embodiments, the plurality of pinholes 104 are distributed on the OCA optical adhesive layer 102 at equal intervals.
[0048] In some exemplary embodiments, the spacing between adjacent pinholes 104 is 0.4 - 0.6 mm.
[0049] In some exemplary embodiments, the diameter of the pinholes 104 is 20 - 40 um.
[0050] In some exemplary embodiments, a centrifugal film layer 103 is provided on the side of the OCA optical adhesive layer 102 facing away from the film layer 101.
[0051] In some exemplary embodiments, the centrifugal film layer 103 includes a centrifugal film.
[0052] In some exemplary embodiments, as needed, before the OCA optical adhesive layer 102 is attached to the film layer 101, both sides of the OCA optical adhesive layer 102 can be wrapped by the centrifugal film layer 103. Tear off the centrifugal film on one side, attach the side of the OCA optical adhesive layer 102 after tearing off the centrifugal film layer 103 to the film layer 101, and then tear off the other centrifugal film layer 103 as needed.
[0053] In some exemplary embodiments, the centrifugal film layer 103 includes through holes, and the through holes correspond to the pinholes 104.
[0054] In some exemplary embodiments, the through holes corresponding to the pinholes 104 means that their positions correspond to each other, that is, the through holes on the centrifugal film layer 103 overlap with the pinholes 104 on the OCA optical adhesive layer 102.
