Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1 to fig. 13, the flexible display panel 100 and the electronic device 10 provided in the embodiments of the present application solve the problem that the normal flexible display panel cannot be bent in the length direction and the width direction at the same time, and thereby improve the experience effect of the electronic device using the flexible display panel. Taking a flexible display panel of an OLED (organic light-Emitting Diode) panel and an electronic device of a mobile phone as an example, a normal OLED panel is designed to be bent in a width direction of the mobile phone, so that the OLED panel can exhibit a 3D display effect. When the OLED panel is bent in the width direction, the OLED panel cannot be bent in the length direction. If the bending is forced in the length direction of the OLED panel, the edge of the OLED panel may be wrinkled. The wrinkled OLED panel is a defective panel and cannot be used in actual electronic devices.
Referring to fig. 1 and fig. 2 together, based on the above-mentioned problems, the present application provides a flexible display panel 100. The flexible display panel 100 includes a front view portion 110 and side view portions (121, 122). The main viewing portion 110 generally takes the shape of a flat rectangle as a whole. The side view portions (121, 122) are curved with respect to the front view portion 110, and the surfaces of the side view portions (121, 122) are formed into a smoothly curved arc shape as a whole. It should be understood that the direction in which the side view portions (121, 122) are bent refers to a direction toward a display surface away from the main view portion 110, which is a surface of the main view portion 110 or the flexible display panel 100 on which a screen is presented.
The Flexible display panel 100 is further provided with Circuit connection terminals 123 at edges of the side view portions (121, 122), and the Circuit connection terminals 123 are used for being connected to components such as a Flexible Printed Circuit (FPC) so that the Flexible display panel 100 can present pictures and information transmitted through the FPC. Based on this, when the flexible display panel 100 is applied to the electronic device 10, the main viewing portion 110 is a portion where the user views the flexible display panel 100, and the side viewing portions (121, 122) are portions where the user views the flexible display panel 100. Based on this, the main viewing portion 110 is located in the middle of the flexible display panel 100; the front view portion 110 has a larger area than the side view portions (121, 122) for the user to obtain the images and information presented by the flexible display panel 100.
In one possible implementation, the front view portion 110 and the side view portions (121, 122) refer to two integrally molded parts of the flexible display panel 100. Such as: the flexible display panel 100 having the main viewing portion 110 and the side viewing portions (121, 122) in the embodiments of the present application is formed by performing a cutting process on corners of the flexible display panel 100 in a manufacturing process.
In one possible implementation, when the flexible display panel 100 of the embodiments of the present application is applied in the electronic device 10 and presents a picture for a user to enjoy, both the front view portion 110 and the side view portion are used for display, and the side view portion (121, 122) is a display area closer to the rear cover of the electronic device 10 or farther away from the user relative to the front view portion 110. The front view portion 110 and the side view portion cooperate together and the flexible display panel 100 exhibits a 3D display effect as a whole. Since the side view portions (121, 122) of the embodiments of the present application are bent in the length direction and the width direction of the electronic device 10, the flexible display panel 100 may provide a more realistic 3D effect to improve the user experience of the electronic device 10.
It should be understood that the length direction of the electronic device 10 and the length direction a of the flexible display panel 100 are the same, and the length direction a refers to the direction of the long side of the electronic device 10 or the flexible display panel 100; accordingly, the width direction of the electronic device 10 and the width direction b of the flexible display panel 100 are also the same, and the width direction b refers to the direction of the short side of the electronic device 10 or the flexible display panel 100. That is, the length direction a of the flexible display panel 100 in the embodiments of the present application may also refer to the length direction of the electronic device 10. In analogy, the width direction b of the flexible display panel 100 in the embodiments of the present application may also refer to the width direction of the electronic device 10.
Referring to fig. 3 and 4, in one possible embodiment, the side view portions (121, 122) include a first side view portion 121 and a second side view portion 122 curved relative to the main view portion 110. The first and second side view portions 121 and 122 are curved in different directions of the main view portion 110. The first side view portion 121 is curved along the width direction b of the main view portion 110, and the second side view portion 122 is curved along the length direction a of the main view portion 110. The first side view portion 121 and the second side view portion 122 are disposed around an edge of the main view portion 110. Accordingly, in order to remove wrinkles generated by the intersection when the normal flexible display panel is bent in the longitudinal direction a and the width direction b at the same time, the outer contour of the main viewing part 110 includes a corner section 111, and the corner section 111 is connected between the first side viewing part 121 and the second side viewing part 122.
Referring to fig. 3 and 4, the outer contour of the first side view portion 121 includes a first segment 121a and a second segment 121b with smooth transition. The second segment 121b is connected between the first segment 121a and the corner segment 111, and the second segment 121b is gradually closer to the front view portion 110 as approaching the corner segment 111, so that the second segment 121b and the corner segment 111 smoothly transition. Corresponding to the first side viewing portion 121, the outer contour of the second side viewing portion 122 includes a third segment 122a and a fourth segment 122b with smooth transition, the third segment 122a is connected between the corner segment 111 and the fourth segment 122b, and the third segment 122a is gradually close to the main viewing portion 110 as the corner segment 111 is close, so that the third segment 122a and the corner segment 111 are smoothly transited. The fourth section 122b is provided with a circuit connecting terminal 123 for connecting an FPC.
The flexible display panel 100 in the embodiments of the present application deals with a region in a normal flexible display panel where wrinkles are likely to occur. Such as: the area where wrinkles are likely to occur is cut, and a part of the front view portion 110 is exposed in the cut area where wrinkles are likely to occur, and the outer contour of the exposed part of the front view portion 110 is a corner section 111. Accordingly, the first side view portion 121 and the second side view portion 122 do not meet each other even if they are bent in the width direction b and the length direction a, respectively, by the corner section 111, and thus the first side view portion 121 and the second side view portion 122 are prevented from being bent and wrinkled. Thus, the flexible display panel 100 can realize bending in the length direction a and the width direction b based on cooperation of the main viewing portion 110, the first side viewing portion 121, and the second side viewing portion 122.
It should be understood that, in order to facilitate understanding of the technical solution of the present application, the display surface of the flexible display panel 100 of each embodiment of the present application is substantially rectangular, that is, the number of the first side view portions 121 and the second side view portions 122 is two. The two first side viewing portions 121 are disposed opposite to each other, and the two second side viewing portions 122 are disposed opposite to each other. Both ends of the two second side viewing portions 122 are respectively connected to the corresponding first side viewing portions 121 through corner sections 111. It should be understood that the four corner sections 111 of the main viewing portion 110 are exposed between the two first side viewing portions 121 and the two second side viewing portions 122, so that the flexible display panel 100 can match with a common mobile phone or tablet computer. However, the flexible display panel 100 of the present application is not limited thereto and can be only rectangular. The display surface of the flexible display panel 100 may also be substantially triangular or pentagonal, etc.; the electronic device 10 to which the flexible display panel 100 is applied is not limited to a mobile phone or a tablet computer, and may also be a car navigator or a face recognition device.
In order to make the flexible display panel 100 more natural as a whole and improve the experience effect of the electronic device 10 using the flexible display panel 100, the second segment 121b, the corner segment 111, and the third segment 122a can be convex relative to the main viewing portion 110. It should be understood that the corner segment 111 is at the front or rear most portion along the diagonal of the flexible display panel 100, i.e. the corner segment 111 is located at the corner of the flexible display panel 100.
It is contemplated that when a user picks up a cell phone or the like type of electronic device 10, the front of the electronic device 10 is the area that the user is primarily viewing. The overall outline of the front surface of the electronic device 10 is mainly affected by the outline of the display panel, and accordingly, the structure of the middle frame is determined by the shape of the display screen; in addition, this is especially true for electronic devices 10 that normally seek higher screen ratios (e.g., narrow bezel designs or full screen designs). In this regard, the flexible display panel 100 in the embodiments of the present application sets the outer contours of the second segment 121b, the corner segment 111 and the third segment 122a to be in the shape of a convex arc, so that when the flexible display panel 100 is applied to the electronic device 10, the front surface of the electronic device 10 does not have an unnatural gap or a concave transition in the corner region, so as to better conform to the usage habit of the user.
In one possible embodiment, the first segment 121a and the fourth segment 122b are both linear, or the first segment 121a and the fourth segment 122b are understood as line segments. The second segment 121b is smoothly connected between the first segment 121a and the corner segment 111, and the third segment 122a is smoothly connected between the fourth segment 122b and the corner segment 111. It should be understood that the second segment 121b and the third segment 122a are curved, so that the flexible display panel 100 exhibits a smooth transition effect in the corner region.
In a possible embodiment, the second segment 121b, the corner segment 111 and the third segment 122a are connected in sequence to form a convex arc shape based on a bezier curve. It should be understood that the control points of the bezier curve are all located on the side of the bezier curve away from the main view 110. By defining the outer contour of the flexible display panel 100 by the bezier curve, the transition between the first side viewing portion 121, the second side viewing portion 122 and the main viewing portion 110 can be more smooth and natural, and no protrusion or depression occurs on the edge of the flexible display panel 100 because of the transition.
Referring to fig. 4, in a possible embodiment, the corner section 111 is a circular arc curve, a line in a radial direction of a midpoint O of the corner section 111 is taken as a center line, and the second section 121b and the third section 122a are symmetrically distributed on two sides of the center line. It should be understood that, by the second segment 121b and the third segment 122a being symmetrically distributed with respect to the midpoint O, while the bending in the length direction a and the width direction b is satisfied, the flexible display panel 100 may present symmetrical and smoothly transitional lines at the corners, so as to improve the use experience of the user.
Referring to fig. 3 and 4 again, in one possible embodiment, the front view portion 110 includes a first long side 110a and a first short side 110 b. The first long side 110a, the corner section 111 and the first short side 110b are sequentially connected to each other, thereby defining the shape and size of the front view portion 110. It should be understood that the first long side 110a is a common boundary of the main viewing portion 110 and the first side viewing portion 121, and the first short side 110b is a common boundary of the main viewing portion 110 and the second side viewing portion 122. The intersection point N where the first long side 110a and the first short side 110b extend to intersect is located outside the flexible display panel 100, so that the possibility of wrinkles occurring in the first side view 121 and the second side view 122 due to excessive bending is reduced.
In one possible embodiment, the length of the first side view portion 121 is less than the length of the main view portion 110; the length of the second side viewing portion 122 is less than the width of the main viewing portion 110. Therefore, the area where the main viewing portion 110 is longer than the first side viewing portion 121 and the main viewing portion 110 is longer than the second side viewing portion 122 is the area including the corner section 111 as described above. Accordingly, the first side view portion 121 and the second side view portion 122 are not in contact with each other, so that the first side view portion 121 and the second side view portion 122 are subjected to bending processing.
Referring to fig. 5 and 6, in one possible embodiment, the included angle α between the first side view portion 121 and the main view portion 110 is greater than 0 ° and less than or equal to 89 ° according to the difference of the required display effect. It should be understood that the included angle α is any angle between 0 ° and 89 °, for example, the included angle α is 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, or 80 °. It should be understood that the larger the included angle α between the first side view portion 121 and the main view portion 110 is, the more realistic the 3D effect presented by the flexible display panel 100 is; accordingly, the bending between the first side view part 121 and the main view part 110 is more pronounced, and the viewing angle of the flexible display panel 100 is increased accordingly. Thus, the flexible display panel 100 can provide different visual experiences according to the use requirements.
Referring to fig. 7 and 8, in one possible implementation, the included angle β between the second side view portion 122 and the main view portion 110 is greater than 0 ° and less than or equal to 89 ° compared to the included angle α between the first side view portion 121 and the main view portion 110. It should be understood that the included angle β is any angle between 0 ° and 89 °, for example, the included angle β is 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, or 80 °. The bottom of fig. 7 shows a circuit connection terminal 123 at the fourth section 122b connected to the second side view portion 122 for connection of an FPC.
Referring to fig. 9, an embodiment of the present application further provides an electronic device 10, where the electronic device 10 includes: a device body 300, a cover plate 200, and the flexible display panel 100 in the above embodiments. The device body 300 may include necessary or unnecessary components such as a processor, a camera, and a speaker, without limitation. The flexible display panel 100 is provided on the apparatus body 300 and electrically connected to the apparatus body 300 to display a picture transmitted by the apparatus body 300. The cover 200 is attached to the flexible display panel 100 such that the flexible display panel 100 is positioned between the apparatus body 300 and the cover 200, thereby protecting the flexible display panel 100. By the flexible display panel 100 having the main viewing part 110, the first side viewing part 121 and the second side viewing part 122, the electronic device 10 can provide a more realistic 3D display effect to improve the experience effect of the user and the product competitiveness.
Referring to fig. 9 to fig. 12, the cover plate 200 provided in the embodiments of the present application may be adapted to the flexible display panel 100 in the embodiments described above, so as to cover the display side of the flexible display panel 100 and protect the flexible display panel 100. Corresponding to the flexible display panel 100 in the above embodiments, the cover plate 200 includes: a body portion 210, a first curved portion 221, and a second curved portion 222. The body portion 210 generally takes a planar shape as a whole. The first and second curved portions 221 and 222 are curved with respect to the body portion 210 and have a shape of a rounded curved surface as a whole. It should be understood that the main body portion 210 of the cover plate 200 is a portion corresponding to the main viewing portion 110 of the flexible display panel 100, and the first and second curved portions 221 and 222 of the cover plate 200 are portions corresponding to the first and second side viewing portions 121 and 122 of the flexible display panel 100, respectively, to achieve a gap-free or bubble-free attachment.
In one possible embodiment, the main body 210, the first curved portion 221, and the second curved portion 222 refer to integrally molded portions of the cap plate 200. Taking the glass cover plate 200 as an example, an unformed glass material in a manufacturing process is subjected to a bending process by a mold of a graphite mold or the like to form the cover plate 200 having the main body portion 210, the first bent portion 221, and the second bent portion 222.
Corresponding to the flexible display panel 100 in the above embodiment, the first bending part 221 of the cover plate 200 is bent along the width direction d of the main body part 210, and the second bending part 222 is bent along the length direction c of the main body part 210. The first and second bent portions 221 and 222 are disposed around the edge of the body portion 210. In order to eliminate wrinkles generated by the intersection when the main body 210 is bent in the longitudinal direction c and the width direction d at the same time, the main body 210 further has an outer contour including a buffer section 211, and the buffer section 211 is connected between the first bent portion 221 and the second bent portion 222.
In a possible implementation manner, the cover plate 200 provided in the embodiment of the present application is a transparent cover plate 200, and the transparent cover plate 200 may be a glass cover plate or a sapphire cover plate, and it should be understood that the material of the cover plate 200 is not limited by the present application. Accordingly, the first bending part 221 and the second bending part 222 are bent in the same direction of the main body part 210, so that the first bending part 221 and the second bending part 222 bent in the same direction can be attached to the first side viewing part 121 and the second side viewing part 122 of the flexible display panel 100 without a gap, and air bubbles can be prevented from being generated.
Referring to fig. 11, the outer profile of the first bending portion 221 includes a fifth section 221a and a sixth section 221b with smooth transition. The sixth segment 221b is connected between the fifth segment 221a and the buffer segment 211, and as the buffer segment 211 is approached, the sixth segment 221b is gradually approached to the main body portion 210, so that the sixth segment 221b and the buffer segment 211 are smoothly transited. The outer contour of the second bending portion 222 includes a seventh section 222a and an eighth section 222b with smooth transition corresponding to the first bending portion 221, the seventh section 222a is connected between the buffer section 211 and the eighth section 222b, and the seventh section 222a is gradually close to the main body portion 210 as approaching to the buffer section 211, so that the seventh section 222a and the buffer section 211 are smoothly transited. Thus, the sixth segment 221b, the buffer segment 211 and the seventh segment 222a can be in a convex arc shape protruding relative to the main body portion 210 as a whole, so that the cover plate 200 can be attached to the flexible display panel 100 in the above embodiment.
In one possible embodiment, the sixth section 221b, the buffer section 211 and the seventh section 222a are connected in sequence to form a convex arc shape based on a bezier curve. It should be understood that the control points of the bezier curve are all located on the side of the bezier curve away from the main body portion 210. The outer contour of the cover plate 200 is defined by the bezier curve, so that the transition between the first bending part 221, the second bending part 222 and the main body part 210 can be more smooth and natural, and no protrusion or depression occurs on the edge of the cover plate 200 due to the transition, so as to improve the experience effect of the user.
Referring to fig. 11, in one possible embodiment, the main body 210 includes a second long side 210a and a second short side 210 b. The second long side 210a, the buffer section 211 and the second short side 210b are connected in sequence and thus define the shape and size of the main body 210. It should be understood that the second long side 210a is a common boundary of the body portion 210 and the first bent portion 221, and the second short side 210b is a common boundary of the body portion 210 and the second bent portion 222. The intersection point M at which the second long side 210a and the second short side 210b extend to intersect is located outside the cap plate 200, thereby reducing the possibility that the cap plate 200 is cracked or scrapped due to excessive bending of the first bent portion 221 and the second bent portion 222.
In one possible embodiment, the length of the first bending part 221 is less than the length of the main body part 210, and the length of the second bending part 222 is less than the width of the main body part 210. Thus, the area where the main body portion 210 is longer than the first bending portion 221 and the main body portion 210 is longer than the second bending portion 222 is the area including the buffer section 211 as described above. Based on this, there is no contact between the first bent portion 221 and the second bent portion 222, so that the first bent portion 221 and the second bent portion 222 are subjected to the thermal bending process by the mold.
In one possible embodiment, the included angle between the first bending portion 221 and the main body portion 210 is greater than 0 ° and less than or equal to 89 °, depending on the display effect required and the attachment to the flexible display panel 100. That is, the included angle is any angle between 0 ° and 89 °, for example, the included angle is 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, or 80 °. It should be understood that the greater the included angle between the first bending part 221 and the main body part 210, the more pronounced the bending between the first bending part 221 and the main body part 210. In one possible embodiment, the angle between the second bending portion 222 and the main body portion 210 is greater than 0 ° and less than or equal to 89 ° compared to the first bending portion 221. The included angle between the second bending portion 222 and the main body portion 210 is any angle between 0 ° and 89 °, for example, 10 °, 20 °, 30 °, 40 °, 50 °, 60 °, 70 °, or 80 °.
In one possible implementation, when the cover 200 and the flexible display panel 100 are assembled in the electronic device 10, the flexible display panel 100 displays the display content, and the cover 200 is located on the display side of the display panel or on the side of the display panel facing away from the inside of the electronic device 10. The cover plate 200 protects the flexible display panel 100, and the cover plate 200 is also a component that is in direct or indirect contact with a user. In this regard, in order to provide a more comfortable tactile sensation and improve the user experience, referring to fig. 12, the edge of the first bent portion 221 of the cover plate 200 has a 2.5D-processed curved transition surface. It should be understood that the edge refers to an edge of the first bending part 221 away from the body part 210. By analogy, the edge of the second bend 222 also has a 2.5D processed curved transition surface. By the first and second curved portions 221 and 222 having 2.5D processed edges, the cover plate 200 can be more closely attached to the middle frame of the electronic device 10, and the transition between the cover plate 200 and the middle frame is more smooth and natural for the user to take.
It should be understood that the 2.5D process refers to a special process of skiving or the like the edges of the cover plate to form a curved surface on the edges of the cover plate while the middle portion of the cover plate remains planar. Overall, the edges of the 2.5D treated cover plate exhibited a rounded transition. The 2.5D treated cover plate may have a greater drop resistance than a flat type cover plate. When the user uses the electronic device having the 2.5D-processed cover plate, the palm of the user may be bent and brought into contact with the edge of the cover plate, and thus, the cover plate having the 2.5D-processed cover plate may be more ergonomic.
The first bending portion 221 and the second bending portion 222 bent with respect to the main body portion 210 can also expand the screen presented by the flexible display panel 100 to some extent; based on this, the first and second curved parts 221 and 222 having the edge of the 2.5D process may make the picture enjoyed by the user more toward the effect of 3D.
In one possible embodiment, when the cover plate 200 is still on an unfixed planar substrate, the planar substrate is processed by a CNC (Computer Numerical Control) machine to remove the corners of the planar substrate, and the edges of the planar substrate after the corners are removed are polished to form 2.5D curved transition surfaces on the edges of the planar substrate. Then, the planar substrate is thermally bent by a graphite mold to form the cap plate 200 having the body portion 210 and the first and second bent portions 221 and 222 having 2.5D edges.
In one possible embodiment, since the cover plate 200 provided by the present application is provided with the first bending portion 221 and the second bending portion 222 which are bent with respect to the main body portion 210, the cover plate 200 may serve as a mold for the flexible display panel 100 in the above embodiments. Such as: the unbent flexible display panel 100 is pressed and fixed into the cover plate 200 by a transparent Adhesive such as OCA (optical Clear Adhesive). The assembly steps of the electronic device 10 using the flexible display panel 100 and the cover 200 are simplified by bending the unbent flexible display panel 100 in a form of being attached to the surface of the cover 200 through the first bending part 221 and the second bending part 222 bent with respect to the body part 210.
Referring to fig. 13, in a possible implementation, the electronic device 10 further includes: a polarizer 400. The polarizer 400 is configured to have the same shape as the surface of the flexible display panel 100 to be attached to the flexible display panel 100 without a gap and without wrinkles. Correspondingly, the corners of the polarizer 400 are removed to form a convex arc shape. In a subsequent process, the cover 300 is disposed on the polarizer 300.
In another possible embodiment, the cover plate 200 provided by the present application may be matched with a normal display panel to better protect the display panel and make it possible to provide a richer display effect.
In another possible embodiment, the cover plate 200 provided in the present application can be used on a rear cover of the electronic device 10 besides being covered with the flexible display panel 100, so as to improve the user experience.
