As shown in fig. 1 to 7, an embodiment of the present invention provides an electronic device, including:

a flexible screen 1;

the cover plate 2 covers the flexible screen 1, and the cover plate 2 comprises a first cover plate 21 and a bendable second cover plate 22 connected with the first cover plate 21;

wherein, when the flexible screen 1 is in the unfolded state, the second cover plate 22 is in a flat state; when the flexible screen 1 is in a folded state, the second cover plate 22 is in a bent state.

Specifically, apron 2 be first apron 21 with the apron that second apron 22 carries out the concatenation sets up the second apron 22 that can buckle in the department that needs buckle, sets up first apron 21 in the department that need not buckle, not only make full use of the deformation characteristic of second apron 22, can also improve the hardness on flexible screen 1 surface, avoid folding in-process to damage flexible screen 1.

Further, the first cover plate 21 may be a hard glass cover plate, and the second cover plate 22 may be a deformable glass cover plate.

In particular, the second cover plate 22 is a flexible, bendable glass cover plate, with a thickness of deformable glass that may be in the order of hundreds of microns, for example: the minimum bending radius of the flexible glass with the thickness of 100 microns can reach 5mm, and the thinner the thickness is, the larger the value of the minimum bending radius is, and the stronger the elastic deformation performance is.

In the embodiment of the invention, the bendable second cover plate 22 is used for folding the electronic equipment, the second cover plate 22 is in a bent state when the flexible screen 1 is in a folded state, the problem that the shape of the electronic equipment is limited due to the limitation of a high-pressure hot bending manufacturing process of the first cover plate 21 is solved, and the hardness of a surface protection layer of the flexible screen of the electronic equipment is considered.

As shown in fig. 3, further, the electronic device may further include:

the upper surface and the lower surface of the cover plate 2 are provided with the first PI films 3.

Specifically, the cover plate 2 covers the flexible screen 1, the upper surface and the lower surface of the cover plate 2 are respectively covered with the first PI film 3, and the cover plate 2 and the flexible screen 1 can be protected.

As shown in fig. 3, further, the thickness of the second cover plate 22 is the same as that of the first cover plate 21.

Specifically, the second cover plate 22 may be a one-layer or multi-layer structure, and the thickness of the second cover plate 22 is the same as that of the second cover plate 21, so as to form a layer of cover plate 2 covering the flexible screen 1 by splicing, and protect the flexible screen 1.

As shown in fig. 3, further, the second cover plate 22 may include:

a multi-layer sub-cover 221;

and a second PI film 222, wherein the second PI film 222 is disposed on surfaces of the sub-cover plates 221 of two adjacent layers, which are close to each other.

Specifically, in the case that the second cover plate 22 is formed by stacking a plurality of sub-cover plates 221, two layers of second PI films 222 are disposed between each two adjacent sub-cover plates 221, and the two layers of second PI films 222 are respectively connected to the sub-cover plates 221, that is, the upper and lower surfaces of the sub-cover plates 221 are both provided with PI films (the first PI film and/or the second PI film) to protect the sub-cover plates 221 of each layer.

As shown in fig. 3, further, the second PI films 222 on the sub-cover 221 of two adjacent layers are bonded by a first adhesive 4.

Specifically, if the second cover plate 22 is formed by stacking a plurality of sub-cover plates 221, the second PI films 222 on the sub-cover plates 221 of two adjacent layers may be bonded by the first adhesive 4 to form the second cover plate 22 of a multi-layer structure; the first Adhesive 4 may be Optical Clear Adhesive (OCA) or the like.

Specifically, the space between the first cover plate 21 and the second cover plate 22 above the flexible screen 1 may be filled and bonded by a deformable second adhesive 5, where the second adhesive 5 may be an adhesive such as a soft OCA, and may be used to bond a transparent optical element (such as a lens), and a layer of the first PI film 3 may be disposed on both the upper surface and the lower surface of the first cover plate 21 and the second cover plate 22.

Further, when the second cover 22 is in the flat state, the length of the cross section of the second adhesive 5 near the first surface of the flexible screen 1 is the same as the length of the cross section of the second surface far from the flexible screen 1.

When the second cover plate 22 is in a bent state, the second adhesive 5 is in a stretched state, and the length of the cross section of the first surface is smaller than that of the cross section of the second surface.

The volume of the second adhesive 5 in the flat state of the second cover 22 may be the same as the volume of the second adhesive 5 in the folded state of the second cover 22.

Specifically, as shown in fig. 2 and 7, when the flexible screen 1 needs to be switched between the unfolded state and the folded state, if the flexible screen 1 is in the unfolded state, and the first cover plate 21 and the second cover plate 22 are both in the flat state, the second adhesive 5 (for example, OCA) between the first cover plate 21 and the second cover plate 22 is in the non-stretching deformation state, the length of the OCA glue in the cross section is equal, and the gap between the first cover plate 21 and the second cover plate 22 is filled with the OCA glue.

Specifically, as shown in fig. 1 and 4 to 6, if the flexible screen 1 is in a folded state, the first cover plate 21 is still in a flat state, the second cover plate 22 is in a bent state due to folding of the flexible screen 1, the second adhesive 5 (for example, OCA) between the first cover plate 21 and the second cover plate 22 is in a stretching deformation state, and since the lengths of the inner and outer thin glass layers of the second cover plate 22 are unchanged, but the bending radii at different thicknesses are different, the lengths of the upper and lower OCA layers are different, and the gap between the first cover plate 21 and the second cover plate 22 can be compensated by elastic deformation of the OCA adhesive.

As shown in fig. 2, 6 and 7, further, the electronic device may further include:

a first body 7;

a second body 8, said second body 8 being connected to said first body 7 by means of a hinge 6;

the flexible screen 1 is disposed on the first body 7 and the second body 8.

Specifically, the hinge structure 6 may include a hinge 61, and when the flexible screen 1 is switched between the unfolded state and the folded state, that is, when the first body 7 and the second body 8 are switched between the flat state and the stacked state, the hinge 61 hinges two parts of the first body 7 and the second body 8 to perform a fixing function.
