The flexible display cover plate provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
Advances in display technology have enabled intelligent terminal products to be provided with foldable functionality, and such products are also known as flexible terminal products. The structure of the foldable flexible terminal product, such as a smart phone, a tablet and other electronic equipment, comprises a flexible display cover plate, and the flexible display cover plate has a foldable function so as to realize integral bending or folding of the flexible terminal product.
Among them, ultra-thin glass is widely used in flexible display cover plates because of its good flexibility, smooth hand feeling and good uniformity. Generally, after the ultra-thin glass is applied to the flexible display cover plate, laser cutting is required to be performed on the whole cover plate to complete the production and assembly of subsequent products. However, in the laser cutting process of the flexible display cover plate, the cutting edge is very close to the ultrathin glass due to the requirement of the production process, so that the ultrathin glass is very easy to cut, the ultrathin glass is damaged, and the display effect of the display device is further affected.
In view of this, this application provides a flexible display apron, can in time observe the condition of each part in the flexible display apron to and more accurate tracking cutting result.
Fig. 1 is a schematic structural view of a flexible display cover according to an embodiment of the present application, and as shown in fig. 1, the flexible display cover 10 includes a first cover layer 11, an adhesive layer 12, and a second cover layer 13 sequentially arranged along a first direction X.
The first direction X is a height direction of the flexible display cover 10, and may also be referred to as a thickness direction of the flexible display cover 10. In the following, reference is made to the thickness of the first cover sheet layer 11, the second cover sheet layer 13 etc., i.e. to the dimension thereof in the first direction X.
The material of the first cover plate layer 11 may be Polyimide (PI), polyethylene terephthalate (Polyethylene terephthalate, PET), or the like. The first cover sheet layer 11 may have a size in the first direction X of 0.01mm to 0.2mm.
Specifically, the size of the first cover sheet layer 11 in the first direction X may be 0.01mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm or any value in the above range.
The material of the adhesive layer 12 may be a glue substance commonly used in flexible display devices. For example, an optically transparent adhesive film (Optical Clear Adhesive, OCA) may be used.
It should be understood that an adhesive layer is required between the various film layers to achieve bonding, and may or may not be indicated in the drawings, and is not limiting of the present application.
The material of the second cover sheet layer 13 may be ultra thin glass. Specifically, the ultra-thin glass may be soda lime glass, aluminosilicate glass, soda aluminosilicate glass, lithium aluminosilicate glass or phosphor aluminosilicate glass. The second cover sheet layer 13 may have a size of 0.01mm to 0.1mm in the first direction X.
Specifically, the dimensions of the second cover sheet layer 13 in the first direction X may be 0.01mm, 0.03mm, 0.05mm, 0.08mm, 0.1mm or any of the values in the above ranges.
The first cover sheet layer 11 completely covers the second cover sheet layer 13.
By fully covered is meant that the first cover sheet layer 11 fully covers the second cover sheet layer 13 without missing any portion of the second cover sheet layer 13.
Fig. 2 is a schematic structural view of a flexible display cover plate according to another embodiment of the present application. As shown in fig. 2 and 1, the first cover sheet layer 11 includes a View Area 15 (VA Area), an ink Area 112, and a non-ink Area 113, and the ink Area 112 and the non-ink Area 113 are located around the View Area 15.
The periphery of the visible area 15 refers to the area of the first cover plate layer 11 near the first side 111, which is left after the first cover plate layer 11 removes the visible area 15, and the periphery of the visible area 15, that is, the other area except the first cover plate layer 11 of the visible area 15, is used to set the ink area 112 and the non-ink area 113. The specific ratio of the peripheral portion and the visible area 15 to the first cover sheet layer 11 is not limited in this application, and may be set in a range of settings of the visible area 15 and the ink area 112, which are well known in the industry.
It will be appreciated that the non-ink region 113 is disposed on the first cover sheet layer 11 in a portion other than the viewable area 15, i.e., the non-ink region 113 cannot overlap the viewable area 15 in areas.
Wherein the non-ink region 113 is disposed on the first side 111 of the first cover sheet layer 11 to expose the first region 131 of the second cover sheet layer 13.
It should be understood that the non-ink region 113 is disposed on the first side 111 of the first cover sheet layer 11, meaning that the non-ink region 113 is bordered by a portion of the first side 111. Therefore, if it is mentioned below that the non-ink region 113 is disposed on the first side 111, it is actually that the non-ink region 113 is bordered by a portion of the first side 111, thereby forming the non-ink region 113.
The first side 111 of the first cover sheet layer 11 refers to the four sides of the first cover sheet layer 11. The first side 111 of the first cover sheet layer 11 is provided with non-ink areas 113, i.e. the non-ink areas 113 are located on the four sides. The first side 111 refers to the four sides of the first cover sheet layer 11, and the second side refers to the four sides of the second cover sheet layer 13, if mentioned below.
The periphery of the visible area 15 includes an ink area 112 and a non-ink area 113 disposed on the first side 111, and then the area on the second cover sheet layer 13 corresponding to the periphery of the first visible area 15, that is, includes a first area 131 corresponding to the non-ink area 113 and a second area covered by the ink area 112. That is, the first region 131 exists due to the presence of the non-ink region 113. The non-ink region 113 is disposed on the first side 111 of the first cover sheet layer 11, and thus the first region 131 is also present on the second side 132 of the second cover sheet layer 13.
The periphery of the second cover sheet layer 13, which corresponds to the periphery of the visible region 15, includes a second area covered by the ink region 112, and a first area 131 that exists due to the presence of the non-ink region 113. Since the non-ink region 113 is provided to expose the first region 131, the area of the first cover plate layer 11 is larger than that of the second cover plate layer 13. Thus, the area of the non-ink region 113 is not smaller than the area of the first region 131 within a certain tolerance.
In the above-described aspect, the flexible display cover 10 includes the first cover sheet layer 11, the second cover sheet layer 13, and the adhesive layer 12 connecting the two, and the first cover sheet layer 11 includes the visible region 15, and the ink region 112 and the non-ink region 113 disposed around the visible region 15. Wherein the non-ink region 113 is disposed on the first side 111 of the first cover sheet layer 11, and the second cover sheet layer 13 includes the exposed first region 131. The first region 131 is not covered by the ink region 112 due to the presence of the non-ink region 113, that is, the first region 131 is present due to the presence of the non-ink region 113. By providing the non-ink area 113 on the first side 111 of the first cover plate layer 11, the non-ink area 113 is opposite to the first area 131 of the second cover plate layer 13, so that the bonding effect between the second cover plate layer 13 and the first cover plate layer 11 can be directly observed, whether the second cover plate layer 13 is broken can be timely found, and the second cover plate layer 13 can be prevented from being cut in the subsequent processing process.

As shown in figure 5 of the drawings,L 5 、L 6 、L 7 and L 8 Middle L 7 At a minimum, the non-ink region 113 is set at L 7 On the corresponding first sub-side 1111. If L 6 At a minimum, the non-ink region 113 is set at L 6 On the second sub-side 1112 of the corresponding first cover plate layer 11, L 5 And L 8 And the same is true.

In the present embodiment, the second cover sheet layer 13 includes a first region 131 exposed by the presence of the non-ink region 113. During the processing of the flexible display cover sheet 10, the precursor of the flexible display cover sheet 10 is cut but not the second cover sheet layer 13. Therefore, by providing the non-ink region 113 at the side pitch of the first cover sheet layer 11 and the second cover sheet layer 13 is minimum, the situation of the second cover sheet layer 13 at the time of cutting can be more accurately observed.
