Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
Fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention, as shown in fig. 1, the display device includes a display panel 101, where the display panel 101 has a first side and a second side opposite to each other in a width direction; the first side and the second side are bent and extended to the side away from the display surface of the display panel 101, so as to divide the display panel 101 into a flat area 201 and a bent area 202; a window member 102 fitted to the display panel 101 is provided on the display surface side of the display panel 101, and the two are fixed to each other by an adhesive layer 103; the thickness of the adhesive layer 103 corresponding to the bent region 202 is greater than the thickness of the adhesive layer 103 corresponding to the flat region 201.
In the display device provided by the embodiment of the invention, the display panel 101 has the first side and the second side which are arranged oppositely in the width direction, and the first side and the second side are bent and extended to the side away from the display surface of the display panel 101, so that the display panel 101 is divided into the flat area 201 and the bent area 202, thus, a display picture generated by the display panel 101 can be displayed not only in the flat area 201, but also in the bent area 202, a display frame can be hidden at the two sides of the display device, no frame is arranged on a front-view display screen, and the screen occupation ratio is improved. It is understood that the other sides of the display panel 101 may also adopt the same arrangement as described above, and are not described herein again. The display panel 101 may be fixed relative to the window member 102 for protecting the display panel 101 by the adhesive layer 103, i.e., the adhesive layer 103 is located between the display panel 101 and the window member 102, and the adhesive layer 103 and the window member 102 may be bent as the display panel 101 is bent. The thickness of the adhesive layer 103 corresponding to the bending region 202 is greater than the thickness of the adhesive layer 103 corresponding to the flat region 201, and the thickness of the adhesive layer 103 gradually changes along with the bending degree, so that the adhesive layer 103 corresponding to the bending region 202 can form a lens-like structure, and thus the adhesive layer 103 corresponding to the bending region 202 can adjust the light path of light emitted by the display panel 101, thereby avoiding the undesirable refraction of light and the scattering of light, further avoiding or reducing the defects of shadows or image distortion of the display device in the bending region 202, and improving the user experience.
Optionally, the adhesive layer 103 has oppositely disposed first and second surfaces 1031, 1032; in the bending region 202, the curvature of the first surface 1031 of the adhesive layer 103 is different from the curvature of the second surface 1032.
It should be noted that, since the thickness of the adhesive layer 103 corresponding to the bending region 202 is greater than the thickness of the adhesive layer 103 corresponding to the flat region 201, when bending, the bending degrees of the first surface 1031 and the second surface 1032 of the adhesive layer 103 of the bending region 202 may be different, that is, the curvatures of the first surface 1031 and the second surface 1032 of the adhesive layer 103 are different, and the curvatures of the first surface 1031 and the second surface 1032 of the adhesive layer 103 gradually change along with the bending degree, so that a regulating effect may be exerted on the optical path of light emitted by the display panel 101, and undesirable refraction of light and scattering of light may be avoided, and further undesirable shading or image distortion occurring in the bending region 202 may be avoided or reduced.
Optionally, the first surface 1031 of the adhesive layer 103 is adjacent to the display panel 101, and the second surface 1032 is adjacent to the window member 102; in the bending region 202, the curvature of the first surface 1031 of the adhesive layer 103 is smaller than the curvature of the second surface 1032.
Note that, in practical applications, the first surface 1031 of the adhesive layer 103 may be a surface close to the display panel 101, and the second surface 1032 may be a surface close to the window member 102. Because the thickness of the adhesive layer 103 corresponding to the bending region 202 is greater than the thickness of the adhesive layer 103 corresponding to the flat region 201, when the display panel is bent, the curvature of the first surface 1031 of the adhesive layer 103 of the bending region 202 may be smaller than the curvature of the second surface 1032, so that the bending degree of the first surface 1031 may be smaller than the bending degree of the second surface 1032, an adjusting effect is generated on a light path of light emitted by the display panel 101, and undesirable refraction of light and scattering of light are avoided, thereby avoiding or reducing the defects of shadows or image distortion occurring in the bending region 202, and improving user experience. Meanwhile, the adhesive layer 103 can be attached to the display panel 101 with a smaller bending degree, so that stress applied to the display panel 101 by the adhesive layer 103 during bending can be reduced, and damage to the display panel 101 can be avoided.
Optionally, the adhesive layer 103 includes: adhesive sublayer 1033 and bumps 1034; the protrusion 1034 is located on the adhesive sublayer 1033 at a position corresponding to the bending region 202.
It should be noted that, as shown in fig. 2a to fig. 2g, in order to make the thickness of the adhesive layer 103 corresponding to the flat region 201 different from that of the adhesive layer 103 corresponding to the bent region 202, the adhesive layer 103 may be made of a two-part structure of an adhesive sublayer 1033 and a protrusion 1034. The protrusion 1034 is located on the adhesive sublayer 1033 at a position corresponding to the bending region 202. Thus, when bending, the protrusion 1034 may be disposed on a side close to the display panel 101, which may ensure that the curvature of the first surface 1031 of the adhesive layer 103 is smaller than the curvature of the second surface 1032, and the protrusion 1034 may form a lens structure, so as to adjust the optical path of light emitted from the display panel 101, avoid the undesirable refraction of light and the scattering of light, and further avoid or reduce the occurrence of shadows or image distortion defects in the bending region 202. It is understood that the adhesive layer 103 may be made of other multi-layer structures, and the implementation principle is similar to the above implementation principle, and is not described herein again. In practical applications, the adhesive sublayer 1033 may be attached to the window member 102, the protrusion 1034 is formed, and then the protrusion 1034 is attached to the display panel 101, such that the curvature of the first surface 1031 of the entire adhesive layer 103 near the display panel 101 is smaller than the curvature of the second surface 1032 near the window member 102 when the protrusion 1034 is near the display panel 101. The adhesive sublayer 1033 may also be attached to the display panel 101, and then the protrusion 1034 is formed, and then the protrusion 1034 is attached to the window member 102, such that the protrusion 1034 is close to the window member, and the curvature of the first surface 1031 of the overall adhesive layer 103 close to the display panel 101 may be greater than the curvature of the second surface 1032 close to the window member 102. The curvatures of the first surface 1031 and the second surface 1032 of the adhesive layer 103 can be reasonably controlled according to actual needs, so that the effect of the adhesive layer 103 on adjusting the optical path of light emitted by the display panel 101 is achieved.
Optionally, the material of adhesive sublayer 1033 and protrusions 1034 are the same.
It should be noted that, in practical applications, the adhesive sublayer 1033 and the protrusions 1034 may be made of the same material, which can ensure that the two have the same optical characteristics, and is beneficial to adjusting the optical path of the light emitted from the display panel 101.
Optionally, the adhesive sublayer 1033 and the protrusions 1034 are an integrally molded structure.
It should be noted that the adhesive sublayer 1033 and the protrusion 1034 may be an integrally formed structure, and in the preparation process, the adhesive sublayer 1033 and the protrusion 1034 may be formed by a one-step composition process, so that the process difficulty may be reduced, and the preparation cost may be saved.
Optionally, the adhesive sublayer 1033 and the bumps 1034 are of different materials.
It should be noted that, the adhesive sublayer 1033 and the protrusion 1034 may also be made of different materials, and after the adhesive sublayer 1033 is prepared, the protrusion 1034 is formed on the adhesive sublayer 1033, so that the size and shape of the protrusion 1034 can be controlled without affecting the adhesive performance of the adhesive sublayer 1033. For example, the adhesive sublayer 1033 can be made of a material with good adhesive properties, and the protrusion 1034 can be made of a material with good elasticity, which can be prepared without affecting each other.
Optionally, the cross-sectional shape of the protrusion 1034 perpendicular to its extension direction is rectangular, semicircular, or trapezoidal.
It should be noted that, as shown in fig. 2a to fig. 2g, in practical applications, the protrusion 1034 may be made in different shapes, and the cross-sectional shape perpendicular to the extending direction thereof may be a rectangle, a semicircle or a trapezoid, or other shapes, which are not described herein again. It is understood that the projection 1034 may be formed in a one-layer structure, or may be formed in a two-layer or multi-layer structure. When the projection 1034 is formed in a two-layer or multi-layer structure, the material of each layer of the projection 1034 may be the same or different.
Optionally, the material of adhesive sublayer 1033 comprises a polyacrylate, a polyurethane, or an epoxy.
It should be noted that, in practical applications, the material of the adhesive sublayer 1033 may be polyacrylate, polyurethane or epoxy, or may be other transparent materials with good adhesive property, which is not listed here.
Optionally, the material of the window member 102 includes polycarbonate or polymethylmethacrylate.
The window member 102 in the display device may be a transparent cover plate formed of Polycarbonate (PC) or polymethyl methacrylate (PMMA), may have a single-layer structure or a multilayer structure, and may be a glass cover plate, of course, to protect the display panel. Preferably, in the embodiment of the present invention, the window member 102 may be a transparent cover plate formed by Polycarbonate (PC) or polymethyl methacrylate (PMMA), and is more flexible than a glass cover plate in addition to protecting the display panel, and is beneficial to bending during the manufacturing process.
As can be seen from the above description, in the bending region 202, the curvature of the first surface 1031 of the adhesive layer 103 may be smaller than the curvature of the second surface 1032, or the curvature of the first surface 1031 of the adhesive layer 103 may be larger than the curvature of the second surface 1032, so that, in the bending region 202, the adhesive layer 103 may form a lens effect, thereby adjusting the optical path of light emitted by the display panel 101, avoiding the occurrence of undesirable refraction of light and scattering of light, further avoiding or reducing the occurrence of poor shadows or image distortion in the bending region 202, and improving the user experience. In practical applications, the thickness of the overall adhesive layer 103 corresponding to the bending region 202 may be controlled by the structure of the protrusion 1034, such that the thickness of the adhesive layer 103 corresponding to the bending region 202 is greater than the thickness of the adhesive layer 103 corresponding to the flat region 201. In this way, the bending degree of the first surface 1031 may be smaller than the bending degree of the second surface 1032, and the adhesive layer 103 may be attached to the display panel 101 with a smaller bending degree while adjusting the optical path of the light emitted from the display panel 101, so as to reduce the stress applied to the display panel 101 by the adhesive layer 103 during bending and avoid damage to the display panel 101.
It can be understood that the display device provided by the embodiment of the invention can be a mobile phone, a tablet computer, an intelligent television or other terminal equipment.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
