The inventor finds that, in the related art, for a mobile terminal, taking a mobile phone as an example, as shown in fig. 1, a display screen of the mobile phone adopts a four-curved-surface display screen, and the four-curved-surface display screen refers to: on the basis that the left and right screens of the plane screen in the middle are bent, the curved screens at the upper end and the lower end are further added. Compared with a hyperboloid display screen, the four-curved-surface display screen has great improvement on the performance of the screen in the aspects of screen occupation ratio and the like. The current four-curved-surface display screen has shallow fitting depth in a four-corner arc surface area and hardly enters an arc surface Gaussian angle. As shown in fig. 1 (a), fig. 1 (a) is a schematic view of a cellular phone employing a four-curved display, and in fig. 1 (a), the four-curved display of the cellular phone 1 includes a flat surface portion 1b and first curved surface portions 1c, 1d provided on both sides of the flat surface portion 1b in the width direction, and second curved surface portions 1e, 1f provided on both ends of the flat surface portion 1b in the length direction. Fig. 1 (b) shows a schematic structural diagram of a four-curved-surface display screen at a corner thereof, and a dotted line portion in the diagram is a corner of the four-curved-surface display screen.
Further, as shown in fig. 2, (a), (b) in fig. 2 show the gaussian angular positions C of the arc surface of the four-curved-surface display screen, for the four-curved-surface display screen, the gaussian angular positions C are mainly located at the four corners of the four-curved-surface display screen, and when the display screen is attached at the positions, the display screen is simultaneously pressed by the two right-angled arc edges, so that the display screen of the portion needs to have better deformation capability to meet the requirement of generating larger compressive strain due to the smaller display screen area. As shown in fig. 2 (c), fig. 2 (c) shows a stress distribution diagram of corner positions of the four-curved display screen during the attaching, because the nature of the gaussian angle is a 3D spherical surface, the display screen changes from a plane to a curved surface, the surface area is locally compressed, especially, the panel layer of the display screen is a whole film layer, which is prone to have undesirable conditions such as wrinkles and cracks during the attaching, and the position where wrinkles and cracks are most likely to occur during the attaching process is mainly the position of the corner of the panel layer. As shown in fig. 2 (C), the gray portion pointed by the arrow position in fig. 2 (C) shows that the gaussian angular position C is in a stress concentration state.
Based on this, please refer to fig. 3 to fig. 4 together, a curved panel assembly 10 is disclosed in a first aspect of the present application, where the curved panel assembly 10 includes a display panel 11, a light guiding structure 12 and a cover plate 13 (see fig. 8), the display panel 11 includes a planar portion 11a and a curved portion 11b connected to the planar portion 11a, and the curved portion 11b is provided with a notch 110. The light guide structure 12 is disposed at the notch 110, and the light guide structure 12 is used for guiding the light emitted from the display panel 11 to the notch 110 and emitting the light. The cover plate 13 is provided over the flat portion 11a and the curved portion 11b to protect the display panel 11.
The curved surface screen assembly 10 disclosed in the embodiment of the present application sets up the notch 110 through the curved surface part 11b at the display panel 11, utilizes this notch 110 to make the curved surface part 11b break off, thereby can avoid producing stress concentration at the curved surface part 11b and leading to the display panel 11 to appear bad problems such as fold and fracture when laminating, and then can improve the laminating yield of the curved surface screen assembly 10.
Further, a notch 110 is provided in the curved portion 11b of the display panel 11, and due to the existence of the notch 110, no light can be emitted at the notch 110, which affects not only the display effect of the curved panel assembly 10, but also the decorative effect of the appearance of the curved panel assembly 10. Therefore, this application has further set up light guide structure 12 in breach 110 department, utilize light guide structure 12 can lead to breach 110 department and light-emitting with the light that display panel 11 sent, not only can compensate breach 110 department and can't give out light and lead to showing bad problem, also can utilize light guide structure 12 to become the area source with the light of the marginal side direction transmission of breach 110 simultaneously, thereby the light that sends in this breach 110 department is softer, the light that sends with other positions of curved surface screen subassembly 10 is similar, thereby can promote the outward appearance expressive force of curved surface screen subassembly 10 that has breach 110.
It is understood that the curved screen assembly 10 may be applied to a mobile terminal, for example, a mobile phone or a tablet computer, taking a mobile phone as an example, the curved screen assembly 10 is substantially rectangular, the flat portion 11a mainly refers to a central display portion of the display panel 11, and the curved portion 11b mainly refers to an edge display portion of the display panel 11, and the edge display portion surrounds an outer periphery of the central display portion.
In some embodiments, as can be seen from the foregoing, the curved screen assembly 10 can be a four-curved screen assembly, and the curved portion 11b includes two first sub-curved portions 111 at two sides of the flat portion 11a and two second sub-curved portions 112 at two ends of the flat portion 11 a. Each second sub-curved surface portion 112 is connected between two first sub-curved surface portions 111, and the gap 110 is provided at the connection between each first sub-curved surface portion 111 and each second sub-curved surface portion 112. It is understood that the connection point of each first sub-curved surface portion 111 and each second sub-curved surface portion 112 is a corner position of the display panel 11. For example, as shown in fig. 3 and 4, fig. 3 shows that the notch 110 on the display panel 11 is trapezoidal, fig. 4 shows that the notch 110 on the display panel 11 is triangular, and in fig. 3 and 4, the display panel 11 has four corner positions, and the notch 110 is disposed at each corner position. That is, the display panel 11 of the embodiment of the present application has four notches 110, and the four notches 110 are used to disconnect the connection between the first sub-curved surface portion 111 and the second sub-curved surface portion 112, so that the stress of the display panel 11 at the corner position is released, and the problem of wrinkles and cracks occurring in the attaching process due to the stress concentration at the corner position of the display panel 11 is avoided.
In some embodiments, the shape of the notch 110 includes at least one of a rectangle, a trapezoid, a triangle, or a sector, as long as the adjacent first sub-curved surface portion 111 and the second sub-curved surface portion 112 can be disconnected and technically realized, and the shape of the notch 110 is not particularly limited in this embodiment. For example, as shown in fig. 5, fig. 5 is a schematic view of the notch 110 having a trapezoidal shape, and in this case, the light guide structure 12 is omitted in fig. 5. And, as shown in fig. 7, fig. 7 is a schematic view of the case where the shape of the notch 110 is triangular, and in this case, the light guide structure 12 is omitted in fig. 7. It should be understood that the shape of the notch 110 in fig. 5 and 7 is only an example for easy understanding, and does not limit the scope of the present embodiment.
As shown in fig. 6, fig. 6 is an enlarged view of a in fig. 5, and is intended to show the depth and the depth direction of the notch 110 provided on the display panel 11. Further, the notch 110 has a depth s in a first direction X, which is a direction in which the curved portion extends from an edge of the curved portion 11b of the display panel 11 toward the center of the flat portion 11a of the display panel 11 in the unfolded state, and the depth s is less than or equal to 5mm, that is, the depth direction of the notch 110 is a direction along an outer edge of the display panel 11 toward the center of the display panel 11. In order to release the stress, considering that the stress gathered at the corner of the display panel 11 is large, a notch 110 is provided at the corner of the display panel 11, and the depth s of the notch 110 is related to the magnitude of the stress that can be released, and the larger the depth s is, the larger the stress that can be released is. However, if the depth s of the notch 110 is too large, the display effect of the display panel 11 is also greatly affected, and it is mainly based on that, at the notch 110, even if the light guide structure 12 is provided, only light guiding and light transmitting can be realized, but image imaging cannot be realized. Therefore, in the present application, the depth s of the notch 110 should be considered when setting the notch 110, and should not be too large or too small. This application is through the degree of depth s that limits breach 110 being greater than or equal to 5mm, and simultaneously, the degree of depth s of this breach 110 is less than or equal to 15mm, like this, the degree of depth s of breach 110 satisfies the stress of release display panel 11's edge on the basis, can also reduce as far as possible to display panel 11's display area's occupation, reduces the influence to display panel 11's display effect.
Further, in the first direction X, the notch 110 has a first notch portion 110a penetrating through an edge of the curved portion 11b and a second notch portion 110b communicating with the first notch portion 110a, and a width b2 of the second notch portion 110b is smaller than a width b1 of the first notch portion 110 a. Since the second notch portion 110b is closer to the center of the planar portion 11a than the first notch portion 110a, the width b2 of the second notch portion 110b is as small as possible, which can reduce the influence on the display effect of the display panel 11, and the first notch portion 110a is disposed at the edge of the curved portion 11b, and the width b1 of the first notch portion 110a is set larger to facilitate the processing in consideration of the processing process of the notch 110. Therefore, in the present application, the width b2 of the second notch portion 110b is smaller than the width b1 of the first notch portion 110a in the first direction X, so that the influence on the display effect of the display panel 11 can be reduced, and the notch 110 can be easily processed, thereby reducing the processing difficulty.
It is understood that the notch 110 extends from the edge of the curved portion 11b to the direction of the flat portion 11a, i.e. the first notch portion 110a of the notch 110 is located at the edge of the curved portion 11b, and the second notch portion 110b of the notch 110 can be located at the curved portion 11b or the flat portion 11a, depending on the depth s of the notch 110. For example, assuming that the width of the curved portion 11b is 5mm, when the depth s of the notch 110 is 5mm, the depth s of the notch 110 is approximately matched with the width of the curved portion 11b, and then the notch 110 is completely disposed on the curved portion 11 b. When the depth s of the notch 110 is 6mm, and the depth of the notch 110 is greater than the width of the curved portion 11b, the first notch portion 110a of the notch 110 is disposed on the curved portion 11b, and the second notch portion 110b extends from the curved portion 11b to the flat portion 11 a. It can be seen that the notch 110 is disposed on the curved portion 11b or extends from the curved portion 11b to the flat portion 11a, which depends on the width of the curved portion 11b and the depth of the notch 110, but this embodiment is not limited in this respect.
In some embodiments, the display panel 11 may be an OLED (Organic Light-Emitting Diode) display panel 11, so that the display panel 11 has a self-Light-Emitting characteristic, and the Light guide structure 12 can guide Light emitted from the display panel 11 to the notch 110 to achieve Light emission at the notch 110. Of course, the display panel 11 may also be an LCD (liquid crystal display) panel, and in this case, the display panel 11 may further include a liquid crystal layer.
As shown in fig. 8 and fig. 9, it can be known from the foregoing that the light guide structure 12 of the curved panel assembly 10 of the present embodiment can be disposed at the notch 110. In an alternative example, as shown in FIG. 8, FIG. 8 illustrates a stacked configuration of the curved screen assembly 10 in which the light guide structure 12 may be embedded in the gap 110 such that the gap 110 may be covered by the light guide structure 12. In this example, the shape and size of the light guide structure 12 may be approximately matched with the shape and size of the notch 110, so that the light guide structure 12 may cover the notch 110, and further the light guide structure 12 may conduct the light emitted from the display panel 11 to the notch 110, thereby realizing the light emission at the notch 110.
Further, when the light guide structure 12 is embedded in the notch 110, the first optical adhesive 14 may be disposed at a gap between the light guide structure 12 and the notch 110, and the first optical adhesive 14 not only can realize the fixed connection between the light guide structure 12 and the notch 110 to prevent the light guide structure 12 from being separated from the notch 110, but also can cover the gap between the light guide structure 12 and the notch 110 by the first optical adhesive 14, and meanwhile, the light guide structure 12 also has a light transmitting function, and does not affect the light transmission of the notch 110. Alternatively, the first Optical Adhesive 14 may be, but is not limited to, an OCA (Optical Clear Adhesive) or an OCR (Optical Clear Resin).
In this embodiment, the curved panel assembly 10 further includes a heat dissipation layer 16, the heat dissipation layer 16 can be disposed on the first side 11c of the display panel 11, and the heat dissipation layer 16 is used for dissipating heat of the display panel 11.
The adoption inlays the mode of establishing light guide structure 12 in breach 110, can utilize this breach 110 of light guide structure 12 closing cap, can enough realize the leaded light, does not influence the overall structure of curved surface screen subassembly 10 simultaneously yet, reduces the occupation of light guide structure 12 to the inner space of curved surface screen subassembly 10.
Referring to fig. 9, in another alternative example, the light guiding structure 12 may be disposed at least on the curved portion 11b and corresponding to the notch 110, that is, the light guiding structure 12 is not embedded in the notch 110. Specifically, as shown in fig. 9, fig. 9 shows another stacked structure of the curved panel assembly 10, the display panel 11 may include a first side 11c and a second side 11d opposite to each other, the light guide structure 12 may be disposed at least on the curved portion 11b and corresponding to the notch 110, the light guide structure 12 is disposed on the first side 11c, and the cover 13 is disposed on the second side 11 d. The second side 11d of the display panel 11 may be a display side facing a user, and the first side 11c may be an interior side of the display panel 11, i.e. the first side 11c is a non-display side.
The mode that sets up light guide structure 12 in first side 11c of display panel 11 is adopted, and this light guide structure 12 and breach 110's counterpoint and setting of can being convenient for reduce the degree of difficulty that light guide structure 12 set up at display panel 11.
It is understood that the light guiding structure 12 may be disposed at least on the curved portion 11b and includes: the light guide structure 12 may be attached to the curved portion 11b, or a part of the light guide structure 12 may be attached to the curved portion 11b and another part to the flat portion 11 a. It should be noted that, no matter the light guiding structure 12 is completely attached to the curved portion 11b, or the light guiding structure 12 is partially attached to the curved portion 11b, and the other portion is attached to the planar portion 11a, the light guiding structure 12 should be disposed corresponding to the gap 110 and the light guiding structure 12 completely covers the gap 110.
Alternatively, when the light guide structure 12 is disposed on the first side 11c, the light guide structure 12 can be adhered to the first side 11c by means of glue, so that the light guide structure 12 can be prevented from being detached from the first side 11 c.
In some embodiments, the light guide structure 12 may include at least one of a light guide plate, a light guide sheet, or a light guide film, and the material of the light guide film may be PC (Polycarbonate) or PMMA (polymethyl methacrylate). The light guide structure 12 adopts at least one of a light guide plate, a light guide sheet or a light guide film, and the light guide mode is mainly that the dot points arranged at the bottom of the light guide structure are subjected to diffuse reflection so as to convert the point light source into a surface light source, so that the light emitted from the edge of the notch 110 by the display panel 11 can pass through the light guide structure 12, convert the point light source into a surface light source by the light guide structure 12, therefore, when a user observes from the front, the luminous color at the notch 110 is close to the color displayed at other positions of the display panel 11, so that the defect of appearance caused by display incapability due to the arrangement of the notch 110 is effectively overcome, the influence on the display effect of the display panel 11 is reduced, but also can serve the purpose of enhancing the appearance expression of the display panel 11, as shown in fig. 10, fig. 10 is a schematic optical path diagram of the light guide structure 12 guiding light to the notch 110 and being viewed by human eyes of a user.
Alternatively, the light guide structure 12 may be a flexible light guide structure, such that the light guide structure 12 can be adapted to be attached to the curved portion 11b, so as to facilitate the attachment of the light guide structure 12. Considering that the curved screen assembly 10 of the present embodiment is applied to a mobile terminal, in order to satisfy the light and thin design and miniaturization design requirements of the mobile terminal, the light guide structure 12 may include a light guide film, the whole thickness of the light guide film is thinner, so that the curved screen assembly 10 is lighter and thinner as a whole, and the light guide film is a flexible light guide film, so as to be capable of following the curved portion 11b to deform to be attached to the curved portion 11 b.
Further, the shape of the light guide structure 12 is matched with the shape of the notch 110, and the distance h from the outer edge of the light guide structure 12 to the outer edge corresponding to the notch 110 is greater than or equal to 0.2 mm. For example, taking the shape of the notch 110 as a trapezoid as an example, the light guide structure 12 may be a trapezoid light guide film, and the distance h from the outer edge of the light guide structure 12 to the outer edge corresponding to the notch 110 is greater than or equal to 0.2mm, so that the light guide structure 12 can be completely disposed corresponding to and covering the notch 110, and the fitting tolerance of the curved portion 11b when the light guide structure 12 is fitted is effectively covered. For example, the distance h from the outer edge of the light guide structure 12 to the outer edge corresponding to the notch 110 may be 0.2mm, 0.3mm, 0.4mm, or 0.5 mm.
It is worth noting that the distance h from the outer edge of the light guide structure 12 to the outer edge corresponding to the notch 110 may be less than or equal to 1mm, so that the light guide structure 12 can cover the notch 110 on the whole, the area of the light guide structure 12 can be reduced, and the occupation of the light guide structure 12 on the inner space of the display panel 11 can be reduced.
In some embodiments, the curved panel assembly 10 further includes a second optical glue 15, and the second optical glue 15 can be filled in the gap 110 to fill the gap 110, so that the second optical glue 15 not only can seal the gap 110, but also can be used to adhere the light guiding structure 12 to the curved portion 11b, thereby eliminating the need to additionally provide an adhering component to adhere the light guiding structure 12, making the adhering manner simpler and reducing the material usage.
Alternatively, the second Optical Adhesive 15 may include, but is not limited to, OCA (Optical Clear Adhesive) or OCR (Optical Clear Resin).
In some embodiments, the display panel 11 may include a panel layer 113 and a polarizer layer 114 stacked on the panel layer 113, the cover plate 13 may be disposed on the polarizer layer 114, and the light guide structure 12 may be disposed on the panel layer 113. In other words, the polarizer layer 114 is located on the second side 11d of the display panel 11, and the panel layer 113 is located on the second side 11d of the display panel 11. Because the panel layer 113 is mainly a layer where the light emitting structure of the display panel 11 is located, the light guiding structure 12 is disposed on the panel layer 113 and can guide light emitted by the light emitting structure to the notch 110, and then the light is emitted through the cover plate 13 covering the notch 110.
Further, in order to reduce the occupation of the light guide structure 12 on the internal space of the display panel 11 and the influence on other components, the curved panel assembly 10 further includes a heat dissipation layer 16, the heat dissipation layer 16 may be disposed on a side of the panel layer 113 away from the polarizer layer 114, and a position of the heat dissipation layer 16 corresponding to the light guide structure 12 is provided with a clearance recess 160. Specifically, the thickness of the heat dissipation layer 16 is greater than the thickness of the light guide structure 12, so that the clearance recess 160 can be formed in the heat dissipation layer 16 to hide the light guide structure 12 in the clearance recess 160, and thus, even if the light guide structure 12 is formed inside the display panel 11, the light guide structure 12 does not occupy the inner space of the display panel 11, and thus, the influence on other components inside the display panel 11 can be reduced.
Alternatively, the clearance recess 160 may include a clearance groove or a clearance hole.
