Background
With the increase of the consumption level, consumers have increasingly demanded electronic products with not only diversification of functions but also appearance, texture, and the like. Currently, glass materials are widely used in the mobile terminal market, for example, thin plate glass is used for a cover plate of a display screen of an electronic device. Most of the display screens of the conventional electronic equipment are flat display screens, and the appearance homogenization is serious. With the development of curved display technology, curved display screens are increasingly applied to electronic devices, and curved glass serving as a cover plate of a curved display screen is also applied.
However, the current glass cover plate, the preparation method thereof, the display screen and the mobile terminal still need to be improved.
Disclosure of Invention
The present application is based on the discovery and recognition by the inventors of the following facts and problems:
the inventor finds that the problem that the black edges at the upper end and the lower end of the current curved screen are wide is common. The inventor finds that the curved glass cover plate and the flexible display screen cannot be effectively attached in the preparation process of the conventional curved screen through intensive research and a large number of experiments. At present, the edge of a glass cover plate for preparing a curved screen is generally an arc surface (namely, the upper surface and the lower surface of the edge of the glass cover plate are arc surfaces), the arc surface comprises two first arc surfaces symmetrically arranged along a first direction and two second arc surfaces symmetrically arranged along a second direction, and the first direction is perpendicular to the second direction. When the flexible display screen is attached to the glass cover plate, the flexible display screen can be attached to the glass cover plate only along one direction (for example, a first direction), and an area where an arc surface is arranged at the edge of the glass cover plate along another direction (for example, a second direction) is easily wrinkled due to the fact that the bending direction of the arc surface is not consistent with the attaching direction of the flexible display screen, and the flexible display screen cannot be attached effectively. Therefore, when the existing flexible display screen is attached to the glass cover plate, the arc surface area (usually at the edge of the short side direction of the glass cover plate, namely the upper end and the lower end) of the glass cover plate edge perpendicular to the attaching direction needs to be avoided, so that the actual attaching area of the display screen is small, the black edges at the upper end and the lower end of the curved screen are wide, and the preparation of the full-screen is not facilitated. Therefore, if a new glass cover plate can be provided, the glass cover plate not only has a curved surface appearance effect, but also can be comprehensively and effectively attached to a flexible display screen, and the problems can be solved to a great extent.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
In one aspect of the invention, a glass cover plate is provided. Referring to fig. 1 to 3 (fig. 2 is a cross-sectional view taken along AA 'in fig. 1, and fig. 3 is a cross-sectional view taken along BB' in fig. 1), the glass cover plate 1000 includes: a quadrilateral main face 100, two symmetrically arranged arc faces 200 and two symmetrically arranged arc portions 300. Wherein the arc face 200 is provided on an edge of the quadrangular body face 100 and is bent toward the lower surface 110 of the quadrangular main face 100, and the arc portion 300 is provided on an edge of the quadrangular main face 100 where the arc face 200 is not provided. According to an embodiment of the present invention, referring to fig. 3, the thickness D1 of the edge of the quadrilateral main face 100 not provided with the arc face 200 (i.e., the arc 300) is smaller than the thickness D2 of the central region of the quadrilateral main face 100. Therefore, the edge portions of the upper surface of the glass cover plate 1000 are all arc surfaces, the lower surface of the glass cover plate 1000 at the arc surface 200 is an arc surface, and the lower surface at the edge of the glass cover plate 1000 without the arc surface 200 may be a plane or an arc surface having the same bending direction as the quadrilateral main surface 100. From this, this glass apron 1000 not only has curved surface appearance effect, laminates with flexible display screen easily moreover and forms the curved surface screen, is difficult for producing the fold at the laminating in-process, is favorable to preparing the full face screen.
For convenience of understanding, the following detailed description is made of the principle of the glass cover plate according to the embodiment of the present invention to achieve the above technical effects:
the inventor finds that the glass cover plate currently used for manufacturing the curved screen is generally a cambered surface at the edge (i.e. the upper and lower surfaces at the edge of the glass cover plate are both cambered surfaces), the cambered surface comprises two first cambered surfaces symmetrically arranged along a first direction and two second cambered surfaces symmetrically arranged along a second direction, and the first direction is perpendicular to the second direction. When the flexible display screen is attached to the glass cover plate, the flexible display screen can be attached to the glass cover plate only along one direction (for example, a first direction), and an area where an arc surface is arranged at the edge of the glass cover plate along another direction (for example, a second direction) is easily wrinkled due to the fact that the bending direction of the arc surface is not consistent with the attaching direction of the flexible display screen, and the flexible display screen cannot be attached effectively. Therefore, in the existing method for attaching the flexible display screen to the glass cover plate, the cambered surface area of the edge of the glass cover plate with the bending direction different from the attaching direction needs to be avoided, so that the actual attaching area of the display screen is small, the black edges at the upper end and the lower end (or the left end and the right end) of the curved screen are wide, and the method is not beneficial to preparing the full-face screen. In the glass cover plate 1000 according to the embodiment of the present invention, referring to fig. 1 to 3, the upper surfaces at the edges are all arc surfaces, so that a curved surface appearance effect can be achieved. The lower surface of the glass cover plate 1000 at the arc surface 200 is an arc surface, and the lower surface at the edge of the glass cover plate 1000 where the arc surface 200 is not located (i.e., the arc portion 300 in fig. 3) may be a plane or an arc surface having the same bending direction as the quadrilateral main surface 100. Therefore, when the flexible display screen is attached to the glass cover plate 1000 according to the embodiment of the present invention, the flexible display screen can be attached along the direction of the arc surface 200, and the arc surface area (i.e. the arc portion 300 in fig. 3) of the edge of the glass cover plate perpendicular to the attachment direction may be a plane or an arc surface having the same bending direction as the quadrilateral main surface 100, so that the lower surface of the arc portion 300 may not wrinkle during the attachment process, and thus, the flexible display screen can be attached to the glass cover plate in a large area, and no wrinkle is generated, which is beneficial to the preparation of a full-screen.
According to an embodiment of the present invention, the thickness and shape of the quadrangular main face 100 are not particularly limited as long as they can be used to prepare a glass cover plate for a mobile terminal, and may be selected as needed by those skilled in the art. For example, the thickness of the quadrangular main surface 100 may be 0.5 to 1mm, and the quadrangular main surface 100 may be rectangular. According to an embodiment of the present invention, the method of preparing the quadrangular main face 100 and the two arc-shaped faces 200 is not particularly limited, and may be obtained by integral molding, for example. Specifically, the quadrangular main surface 100 and the arc-shaped surface 200 may be formed by performing a hot press process on a flat glass substrate, and the arc-shaped surface 200 is curved toward the lower surface 110 of the quadrangular main surface 100.
According to an embodiment of the present invention, referring to fig. 3 and 4, the lower surface 110 of the quadrilateral main surface 100 may be a plane (as shown in fig. 3) or an arc (as shown in fig. 4). Note that, referring to fig. 4, when the quadrangular main surface 100 is an arc surface, the curved direction of the quadrangular main surface 100 coincides with the curved direction of the arc surface 200, and the lower surface of the arc portion 300 is also an arc surface identical to the curved direction of the quadrangular main surface 100. That is, when the lower surface 110 of the quadrilateral main surface 100 is an arc surface, the center of the circle of the arc surface and the center of the circle of the arc surface 200 are both located below the quadrilateral main surface 100, and at this time, the lower surface of the arc portion 300 may also have an arc surface in accordance with the bending direction of the lower surface 110 of the quadrilateral main surface 100, that is, at this time, the bending directions of the upper surface and the lower surface of the arc portion 300 may not be in accordance. From this, when along the direction at arcwall face 200 place, when laminating glass apron 1000 and flexible display screen, the crooked direction of the lower surface of arc portion 300 also is unanimous with the laminating direction, therefore the region at arc portion 300 place also can effectively laminate with flexible display screen and can not produce the fold, and then can realize flexible display screen and the laminating of glass apron great area, help preparing the full face screen. Referring to fig. 3, when the lower surface 110 of the quadrangular main surface 100 is a plane, the lower surface of the arc-shaped portion 300 is also the same plane as the quadrangular main surface 100, thereby facilitating the attachment of the flexible display panel to the glass cover 1000. When the lower surface of the arc-shaped portion 300 is a plane, it is easier to fit. According to an embodiment of the present invention, the arc face 200 may be located in a long side direction of the quadrangular main face 100, and the arc portion 300 may be located in a short side direction of the quadrangular main face 100. Therefore, when the glass cover plate 1000 is attached to a flexible display screen to form a curved screen, the attachment can be performed along the arc-shaped surface 200, namely the long side direction of the quadrilateral main surface 100, and therefore the service performance of the prepared curved screen is further improved.
According to an embodiment of the present invention, the thickness of the arc part 300 is not particularly limited as long as the arc appearance can be formed on the upper surface of the arc part 300. According to an embodiment of the present invention, the thickness of the arc part 300 is not less than 0.4 mm. Therefore, the appearance effect of the arc-shaped part 300 can be ensured, and the overall mechanical strength of the arc-shaped part 300 is not influenced. According to an embodiment of the present invention, the thickness of the arc part 300 may decrease in a direction from the center of the quadrangular body surface 100 to the edge of the quadrangular body surface 100. According to the embodiment of the present invention, the arc portion 300 may be obtained by processing the upper surface 120 of the quadrangular main surface 100, and the specific processing manner is not particularly limited as long as the arc appearance can be formed on the upper surface of the arc portion 300. Therefore, the upper surface of the arc-shaped part 300 can have the arc-shaped appearance under the condition that the shape of the lower surface of the arc-shaped part 300 is not changed, so that the edge of the glass cover plate 1000 has the arc-shaped appearance effect, the attachment of the glass cover plate 1000 and the flexible display screen is not influenced, and the preparation of a full-face screen is facilitated.
According to an embodiment of the present invention, referring to fig. 3, the width of the arc 300 (i.e., d shown in fig. 3) is not particularly limited as long as it can provide the edge of the glass cover plate having a good arc appearance, and may be, for example, 3mm to 5 mm. The specific size of the width d of the arc-shaped portion 300 may be set according to the thickness of the quadrilateral main surface 100. The width d of the arc portion 300 may be larger when the thickness of the selected quadrangular main surface 100 is larger, and the width d of the arc portion 300 may be smaller when the thickness of the selected quadrangular main surface 100 is smaller. This contributes to forming the arcuate portion 300 having a good appearance. Specifically, when the thickness of the quadrangular body surface 100 is 0.55mm, the width d of the arc-shaped portion 300 may be 3 mm. When the thickness of the quadrangular body surface 100 is 0.7mm, the width d of the arc-shaped portion 300 may be 4 mm. When the thickness of the quadrangular body surface 100 is 1mm, the width d of the arc-shaped portion 300 may be 5 mm.
In another aspect of the invention, a method of making a glass cover plate is provided. The glass cover plate prepared by the method can have the same characteristics and advantages as the glass cover plate described above. According to an embodiment of the invention, referring to fig. 5, the method comprises:
s100: providing a glass substrate
In this step, a glass substrate is provided. According to the embodiment of the present invention, the thickness, size and material of the glass substrate are not particularly limited as long as they can be used for preparing the glass cover plate, and those skilled in the art can select them as needed. For example, the glass substrate may have a thickness of 0.5 to 1mm, and the glass substrate may be rectangular.
S200: performing hot pressing to form arc surface
In this step, the glass substrate described above is subjected to a hot press process to form arc-shaped surfaces at both symmetrical edges of the glass substrate. According to the embodiment of the present invention, only the edge of the glass substrate may be subjected to the thermocompression process so as to form the arc-shaped surfaces bent toward the lower surface of the glass substrate at the two symmetrical edges of the glass substrate. That is, after the hot pressing process, the main surface of the glass substrate except the arc surface may be a plane. According to other embodiments of the present invention, the entire glass substrate may be subjected to the thermocompression treatment, so that not only the arc-shaped surface curved toward the lower surface of the glass substrate may be formed at the edge of the glass substrate, but also the main body surface of the glass substrate other than the arc-shaped surface may be a curved surface, and the curved direction of the curved surface coincides with the curved direction of the arc-shaped surface. Therefore, the curved glass cover plate with rich appearance can be prepared through simple hot pressing treatment, and the requirements of consumers can be met.
S300: cutting to form a glass cover plate
In this step, a cutting process is performed on the upper surface of the glass substrate formed with the arc-shaped face to form a glass cover plate. According to the embodiment of the present invention, the upper surface at the edge of the glass substrate on which the arc surface is not formed may be subjected to a cutting process so as to form the arc portion at the edge of the glass substrate on which the arc surface is not formed. The upper surface of this arc portion can form the arc outward appearance, and the lower surface of this arc portion is the plane, and the glass apron that prepares laminates with flexible display screen easily and forms the curved surface screen, and difficult production fold helps preparing the full screen. According to an embodiment of the present invention, a specific method of performing the cutting process is not particularly limited, and for example, an arc portion may be formed on the upper surface of the glass substrate on which the arc surface is not formed by a numerical control machining (CNC) plus a grinding process. Because the cutting treatment is carried out on the upper surface of the glass substrate, the problem that when 4 edges of the quadrilateral main surface form an arc surface, two bending directions exist on the inner side of the glass substrate, and the bending directions of the two edges of the glass cover plate are not consistent with the attaching direction when the glass cover plate is attached to a flexible display screen subsequently can be avoided.
According to an embodiment of the present invention, specific parameters of the cutting process performed in this step are not particularly limited as long as the arc-shaped portion of the glass cover plate as described above can be formed based on the process of the upper surface of the glass substrate. The position, shape and other features of the arc-shaped part have been described in detail above, and are not described in detail here. Specifically, according to the embodiment of the present invention, in order to prevent the cutting process from damaging the entire mechanical strength of the glass substrate, the cutting process is away from the cutting boundary line on the side of the quadrangular main surface, and the distance to the edge may be 3mm to 5 mm.
In yet another aspect of the present invention, a display screen is presented. According to an embodiment of the present invention, referring to fig. 6, the display screen may include: the glass cover plate 1000 and the flexible display screen 2000 are described above, wherein the flexible display screen is attached to the inner surface of the glass cover plate. Thus, the display screen has all the features and advantages of the glass cover 1000 described above, and thus, the description thereof is omitted. Generally speaking, glass apron and flexible display screen among this curved surface display screen can effectively laminate, and difficult production fold to this display screen realizes the full face screen more easily.
According to an embodiment of the present invention, referring to fig. 7, the length of the flexible display panel attached to the arc-shaped surface of the glass cover plate along the long side direction of the glass cover plate may be smaller than the length of the flexible display panel attached to the main surface of the quadrangle, that is: the flexible display 2000 according to the embodiment of the present invention may have a non-quadrangular structure. The flexible display screen that the laminating was on quadrangle principal plane, mainly used shows that its area is big more, is favorable to realizing the full screen more, promotes user experience, alleviates or solves the display device who uses curved surface glass apron at present, and upper and lower both sides have the problem of wider black edge. The flexible display screen attached to the arc-shaped surface of the glass cover plate is not generally used for displaying but used for setting structures such as function keys, so that the length of the flexible display screen attached to the arc-shaped surface of the glass cover plate is not particularly limited, and the flexible display screen can be set to be shorter on the premise of realizing the functions of the flexible display screen, so that the cost can be saved.
In yet another aspect of the present invention, a mobile terminal is presented. According to an embodiment of the present invention, the mobile terminal includes: the display screen comprises a shell and a display screen arranged on the shell. The housing and the display screen define an accommodation space therebetween, and the display screen may be a display screen as described above. Mainboard and memory setting are in accommodation space, and the memory setting is on the mainboard, and the mainboard links to each other with the display screen. Thus, the mobile terminal has all the features and advantages of the display screen described above, and will not be described herein again.
