Description

Display device

The present invention relates to a display device, and more particularly to a curved display device.

With the advancement of technology, the technology of displays (such as computers or TV screens) has also been continuously developed. Currently, there are flat displays and curved displays that are more common on the market, in which curved displays are comparable to flat displays. Seeing that the image is more balanced and comfortable, it also has a wider panoramic viewing angle and reduces the reflection of external light, so that the user can watch the image of all corners of the curved display without deformation and distortion. Therefore, it has been favored by consumers in recent years.

As shown in FIG. 1 , it is an assembly diagram of a conventional curved display. The main structure of the curved display 60 includes a curved backlight module 61 , a plastic frame 62 and a curved display panel 63 . The curved backlight module 61 is on one side, and the convex portions 621 are provided on both sides of the plastic frame 62. However, in the actual assembly of the above-mentioned conventional curved display 60, the following problems still exist:

First, since the curved display panel 63 must be bent before the curved backlight module 61 is installed, the curved display panel 63 can be easily replaced with the plastic frame without any protection mechanism. In addition to the case where the curved backlight module 61 is in contact with each other to cause scratches or abrasions, the curved display panel 63 is also prone to problems such as cracking or deformation during the bending process, resulting in a substantial increase in manufacturing cost.

Secondly, when the curved display panel 63 is assembled with the plastic frame 62, the curved display panel 63 is limited by the protruding portion 621. However, during the assembly process, the curved display panel 63 may interfere and rub with the protruding portion 621 of the plastic frame 62. In addition to causing assembly difficulties, the curved display panel 63 is also susceptible to scratches, abrasion, and even collision and cracking.

Therefore, how to develop a production rate that can improve the production yield of curved displays to reduce manufacturing costs is a technical issue that the relevant industry must strive to develop and break through.

In view of the above problems, the present invention provides a display device including a plurality of buffer strips, a plastic frame, and a curved display panel. Each of the buffer strips includes a body and a plurality of bumps. The bumps are located on one side of the body and the bumps are spaced apart. Each of the bumps includes a top surface and a gap is formed between two adjacent bumps. The plastic frame has a concave curved surface, and the curved display panel has a relative inner surface and an outer curved surface, wherein the inner curved surface is convex, and the inner curved surface corresponds to and is disposed on the concave curved surface. Wherein, each buffer strip is attached to the two edges of the inner curved surface along the curved contour of the inner curved surface, and the total arc length of the top surface of each convex block is smaller than the arc length of the main body relative to the side of the convex block, Therefore, since the buffer strips are curved corresponding to the curved contour of the inner curved surface, the top surface of each of the bumps and the side of the body with respect to the side of the bump are curved to have an arc length.

The body is in contact with the concave curved surface with respect to one side of the bumps. Relatively speaking, the bumps are in contact with the two edges of the inner curved surface.

Each of the bumps may further include two sides, the top surface contacts the inner curved surface of the curved display panel, and the two sides are located on both sides of the bump and connect the top surface and the body. And wherein the top surfaces of the buffer strips can be connected to each other as a curved surface, and the curved surface can have a first curvature, the body can have a second curvature, and the second curvature can be smaller than the first curvature, in detail, due to the buffer strip It is bent toward one side of the protruding block, so that the curved surface of the top surface of the convex piece is connected to each other with a larger curvature (ie, the radius of curvature of the curved surface is smaller). Additionally, the body may have a first amount of compression, the bumps may have a second amount of compression, and the second amount of compression may be less than the first amount of compression.

Wherein, two adjacent sides of each of the bumps can be connected to each other, and a gap is formed between two adjacent sides of each of the bumps. In addition, the two adjacent sides of each of the bumps may be attached to each other such that the distance of the gap approaches zero or equals zero.

In summary, the present invention can prevent scratches and abrasions of the display panel and the plastic frame from colliding with each other during assembly by transmitting the technical features of the buffer strip on the edge of the display panel. In addition, the buffer strip can increase the strength of the edge of the display panel, so that the display panel can avoid irregular deformation or cracking during the bending operation.

In addition, when the buffer strip is bent toward one side of the protruding block, each of the bumps reduces the amount of compression due to the gap therebetween without touching the pressing, thereby avoiding the unevenness of the surface of the buffer strip during the bending process. Further, the panel is easily slid and fragmented when the panel is assembled.

Furthermore, the concave curved surface of the plastic frame of the present invention has an arc curved surface shape compared with the conventional plastic frame, so that the display panel and the plastic frame do not have mutual interaction during the assembly process. The problem of interference.

First, referring to FIG. 2 and FIG. 3 together, in the embodiment of the present invention, the display device 1 includes a plurality of buffer strips 10, a plastic frame 20, and a curved display panel 30. Each of the buffer strips 10 includes a body 13 and a plurality of bumps 11 . The bumps 11 are located on one side of the body 13 and are spaced apart (see FIG. 3 for details). Each of the bumps 11 includes a top surface 111 and is adjacent to each other. There is a gap 12 between the two bumps 11. The plastic frame 20 has a concave curved surface 21, and the curved display panel 30 has an opposite inner curved surface 31 and an outer curved surface 32, wherein the inner curved surface 31 is a convex surface, and the outer curved surface 32 is a concave surface, and the inner curved surface 31 corresponds to and is disposed. On the concave curved surface 21 of the plastic frame 20. Furthermore, the curved display panel 30 is curved in the Z direction on both sides extending in the X direction to form an inner curved surface 31 and an outer curved surface 32. As shown in FIG. 2, in the present embodiment, the plastic frame 20 is located. Between the backlight module 22 and the curved display panel 30, the plastic frame 20 includes two long frames 201 and two short frames 202. The concave curved surface 21 is the surface of the long frame 201 of the plastic frame 20, and the concave curved surface 21 corresponds to the inner surface. Surface 31. However, in other embodiments, the curved display panel 30 can also be bent in the Z direction on both sides extending in the Y direction, and the concave curved surface 21 is the surface of the short frame 202 of the plastic frame 20 in FIG. 2, and is implemented in other parts. For example, the curved display panel 30 can be bent in the Z direction at both sides of the X direction and the Y direction, wherein the surface of the long frame 201 and the short frame 202 of the plastic frame 20 has a curved surface corresponding to the inner curved surface 31.

Each of the buffer strips 10 is attached to the two edges of the inner curved surface 31 along the curved contour of the inner curved surface 31, that is, the buffer strip 10 is attached to the side edge 302 of the curved display panel 30, and is aligned with the concave surface of the plastic frame 20. In the curved surface 21, since the buffer strip 10 is curved corresponding to the curved contour of the inner curved surface 31, the top surface 111 of each of the bumps 11 and the side of the body 13 with respect to the side of the bump 11 are curved to have an arc length, and The total arc length of the top surface 111 of each of the bumps 11 is smaller than the arc length of the body 13 with respect to one side of the bumps 11 (this can be seen with reference to Fig. 5). In other words, when the buffer strip 10 is not subjected to any external force, it will assume a flat shape and there will be a gap 12 between the adjacent two bumps 11 (as shown in FIGS. 3 and 4), and when the buffer strip 10 is along When the curved profile of the inner curved surface 31 is curved, the plurality of bumps 11 on the buffer strip 10 will be pressed together by compression, so that the distance between the adjacent two bumps 11 is reduced (as shown in FIG. 2). As shown, the total arc length of the top surface 111 constituting each of the bumps 11 is smaller than the arc length of the body 13 with respect to one side of the bumps 11. The curved display panel 30 can be a liquid crystal display panel (LCD panel) and equipped with a backlight module 22 (shown in FIG. 2) to supply sufficient brightness and light source. Alternatively, the curved display panel 30 may be a self-illuminating display panel, such as an OLED (Organic Light-emitting Diode) panel or a PLED (Polymer Light-emitting Diode) panel, so that the backlight module 22 may not be separately provided. In addition, the buffer strip 10 is a flexible strip and is in a bendable state, and the whole material can be plastic, rubber, silicone or foam, etc., but this part is not limited.

In addition, as shown in FIG. 2, the two ends of the buffer strips 10 can be integrally connected to each other to form a frame. In this embodiment, the upper and lower sides of the frame are buffer strips having a plurality of bumps 11. 10, corresponding to the side edge 302 having the same curved contour as the inner curved surface 31, and the left and right sides being the side strip without the bump, corresponding to the side edge 301 of the curved display panel 30, thus, The buffer strip 10 can be integrally molded and manufactured in a manufacturing manner, and the assembly is also more convenient and rapid. In addition, if the four sides of the curved display panel 30 are curved and have a curved outline, the four sides of the frame may be the buffer strips 10 having the plurality of bumps 11 . In short, the side of the curved display panel 30 having a curved profile can be attached with the buffer strip 10 of the present invention.

Referring to FIG. 5 and FIG. 6, FIG. 5 is a schematic view showing the bending of the buffer strip according to the embodiment of the present invention, and FIG. 6 is a partially enlarged view of the buffer strip. In this embodiment, the plurality of bumps 11 are located on one side of the body 13, and the body 13 is in contact with the concave curved surface 21 of the bezel 20 with respect to one side of the plurality of bumps 11 (see FIG. 7 for details). As shown in FIG. 5, each of the bumps 11 further includes two side faces 112. The two side faces 112 are located on both sides of the bumps 11 and connect the top face 111 and the body 13. In addition, the two adjacent side surfaces 112 of each of the bumps 11 are connected to each other, and a gap 12 is formed between the two side faces 112 adjacent to each of the bumps 11. In this embodiment, the gap 12 has a V shape, but Not limited to this. The gap 12 can also be U-shaped or in an irregular shape.

The width d3 of each top surface 111 is proportional to the distance d2 of each top surface 111 and the length L of the buffer strip 10, and the width d3 of each top surface 111 is inversely proportional to the number of the bumps 11. The relationship may be d3 ₌ L-[(n-1)d2] /n, where n is the number of the bumps 11. In addition, the pitch d2 of each top surface 111 may be proportional to the height d1 of the buffer strip 10, and the pitch d2 of each top surface 111 may be inversely proportional to the number of the bumps 11. The relationship may be d2. ₌ θπd1/180(n-1), where n is the number of the bumps 11 and θ is the arc angle after the buffer strip 10 is bent. Further, a preferable range of the pitch d2 of each of the top faces 111 may be between 0.02 mm and 3 mm or between 0.05 mm and 2.5 mm. Further, a 71-inch display device 1 is exemplified. If the condition is that the height d1 of the buffer strip 10 is 5 mm, the pitch d2 of each top surface 111 is 1 mm, and the arc angle θ after the buffer strip 10 is bent is 38.47. Degree, and the length L of the buffer strip 10 is 1679 mm. Through the above relationship d2 ₌ θπd1/180(n-1), n=4.3 can be obtained, so the number of bumps 11 can be set to 5 (take integer), and the transmission relation d3 ₌ L-[(n-1) D2 can be obtained as d3=335 mm, so the width d3 of the top surface 111 of each bump 11 can be 335 mm. However, the above specific relationships and embodiments are for illustrative purposes only and are not limited in practice.

Fig. 7 is a view showing an embodiment in which the buffer strip is disposed only on the inner curved surface of the curved display panel, and Fig. 10 is a schematic view showing the assembly of the display device of the present invention (3). First, please refer to FIG. 7. In this embodiment, the buffer strip 10 is only attached to the two edges of the inner curved surface 31 along the curved surface of the inner curved surface 31 (ie, the side 302 of FIG. 2), so as to buffer. The strip 10 is located between the curved display panel 30 and the bezel 20 to increase the edge strength of the curved display panel 30 to reduce the risk of cracking, and can prevent the curved display panel 30 from directly contacting the concave curved surface 21 of the bezel 20 to avoid surface display. The panel 30 or the plastic frame 20 is scratched and worn. In addition, as shown in FIG. 10, each of the buffer strips 10 can also be attached to the two edges of the outer curved surface 32 along the curved contour of the outer curved surface 32, and the body 13 is in contact with the outer curved surface 32 with respect to one side of the convex blocks 11. Thereby, the inner curved surface 31 and the outer curved surface 32 of the curved display panel 30 are attached with the buffer strip 10 to further increase the strength of the edge of the curved display panel 30, and the curved display panel 30 is prevented from contacting the outer frame 40 to cause scratching. And the situation of wear and tear.

It should be noted that, referring to FIG. 7 and FIG. 10 at the same time, in the present invention, the outer frame 40 is further disposed on the periphery of the plastic frame 20, the curved display panel 30 and the buffer strips 10, so that the plastic frame 20 and the curved surface are displayed. The panel 30 and the buffer strips 10 are protected and limited. The outer frame 40 can be a frame made of metal or plastic, and is wrapped around the plastic frame 20, the curved display panel 30 and the buffer strip 10. Therefore, the plastic frame 20 does not need to have the protrusion 621 (as shown in FIG. 1 ) pressed against the periphery of the upper surface (display surface side) of the curved display panel 30 , for example, a non-visible area, and the curved display panel 30 is prevented from being assembled. The problem of interference occurs in the process of the concave curved surface 21 of the plastic frame 20, and it is not necessary to excessively bend by the protruding portion 621 to prevent the protruding portion 621 from colliding with the curved display panel 30 to be scratched, and the curved display panel 30 can be prevented from being excessively bent. And ruptured. In other embodiments of the present invention, the outer frame 40 may be omitted, and a double-sided tape or a glue may be disposed on the buffer strip 10 for attaching to the side edge 302 of the curved display panel 30 and the concave curved surface 21 of the plastic frame 20. Thereby, the curved display panel 30 and the plastic frame 20 are fixed.

Referring to Figures 2 and 5, the two adjacent sides 112 of each of the bumps 11 can be opposite and conformed such that the distance between the gaps 12 of the adjacent two bumps 11 approaches zero or equals zero. The top surfaces 111 of the buffer strips 10 can be joined to each other as a curved surface 113. And the arc surface 113 has a first curvature, the body 13 has a second curvature, and the second curvature is smaller than the first curvature. In detail, since the buffer strip 10 is bent toward one side of the projection 11 , the curved surface 113 of the top surface 111 of the bump 11 is connected to each other with a larger curvature than the body 13 of the other side. (ie, the radius of curvature of the curved surface 113 is small). The body 13 has a first amount of compression, and the bumps 11 have a second amount of compression, and the second amount of compression is less than the first amount of compression. In detail, for an elongated body which generally does not have spaced-apart bumps, when it is bent to one side, the side is subjected to a larger amount of compression than the other side. In contrast, the buffer strip 10 of the present invention has a plurality of spaced-apart bumps 11 with gaps 12 between the bumps 11, so that when the buffer strips 10 are bent toward one side of the bumps 11 The second compression amount of the block 11 is greater than the first compression amount of the body 13, and each of the bumps 11 reduces the amount of compression due to the gap 12 therebetween without touching the squeeze, thereby avoiding the buffer strip 10 during the bending process. The surface wrinkles are not flat, which further causes the panel to easily slide and break when the panel is assembled.

In addition, as shown in the figures 2 and 10, the plastic frame 20, the buffer strips 10, and the curved display panel 30 have the same degree of curvature, and can be attached to each other during assembly. The outer frame 40 is further disposed on the periphery of the plastic frame 20, the curved display panel 30, and the buffer strips 10, so that the plastic frame 20, the curved display panel 30, and the buffer strips 10 are protected and limited.

Figure 8 is a schematic view showing the assembly of the display device of the present invention (1). Figure 9 is a schematic view showing the assembly of the display device of the present invention (2). Figure 10 is a schematic view showing the assembly of the display device of the present invention (3). Figure 11 is a flow chart showing the assembly method of the display device of the present invention. Referring to FIG. 11, the steps of assembling the display device of the present invention are as follows:

Step S01: providing a plurality of buffer strips 10, each of the buffer strips 10 includes a body 13 and a plurality of bumps 11. The bumps 11 are spaced apart, and each of the bumps 11 includes a top surface 111, and adjacent thereto There is a gap 12 between the two bumps 11, and the shape of the buffer strip 10 can be further shown in FIG. Step S02: A plastic frame 20 is provided. The plastic frame 20 has a concave curved surface 21. As shown in FIG. 5, the plastic frame 20 has an arcuate shape and has a concave curved surface 21. Step S03: A display panel 50 is provided. The display panel 50 has a first side surface 51 and a second side surface 52. Step S04: attaching the buffer strips 10 to the two edges of the first side surface 51. As shown in FIG. 8, the buffer strips 10 are attached to the two edges of the first side surface 51 before the display panel 50 is bent. Step S05: bending the display panel 50 and the buffer strips 10 such that the first side surface 51 has a convex shape corresponding to the concave curved surface 21, so that the total arc length of the top surface 111 of each of the bumps 11 is smaller than that of the body 13 The arc length on one side of the bump 11 is as shown in FIGS. 8 and 9 , and the edge of the first side surface 51 of the display panel 50 is affixed with the buffer strip 10 to strengthen the edge strength of the display panel 50 and The display panel 50 reduces the risk of cracking or irregular deformation during bending. When the display panel 50 is bent, the curved display panel 30 is formed. The first side surface 51 is the inner curved surface 31, and the second side surface 52 is the outer curved surface 32. Step S06: assembling the display panel 50 and the plastic frame 20 so that the first side surface 51 is correspondingly disposed on the concave curved surface 21. As shown in FIGS. 6 and 7, the edge of the first side 51 of the display panel 50 is attached through the attached surface. The buffer strip 10 can prevent the display panel 50 from directly contacting the concave curved surface 21 of the plastic frame 20, thereby preventing the display panel 50 or the plastic frame 20 from being scratched or worn. In addition, please refer to FIG. 1 and FIG. 9 , wherein FIG. 1 is a schematic view showing the assembly of a conventional curved display. The concave curved surface 21 of the plastic frame 20 of the present invention is subtracted from the conventional plastic frame 62. The portion of the protruding portion 621 can cause the first side surface 51 (i.e., the inner curved surface 31) to have no problem of interference during assembly in the concave curved surface 21. In other words, the display panel 50 is disposed on the plastic frame 20 without excessive bending due to the protruding portion 621, thereby preventing the protruding portion 621 from colliding with the display panel 50 and scratching, and also avoiding excessive bending and cracking. Step S07: an outer frame 40 is disposed on the periphery of the plastic frame 20, the display panel 50, and the buffer strips 10 (refer to FIG. 10). In addition, in step S04, the two edges of the buffer strip 10 on the second side surface 52 are further attached, which can be referred to as shown in FIGS. 8, 9, and 10, that is, the first side 51 of the display panel 50. The buffer strips 10 are attached to both edges of the second side 52, which further enhances the strength of the edge of the display panel 50 and prevents the second side 52 of the display panel 50 from contacting or rubbing against the outer frame 40.

It is emphasized again that the buffer strip 10 of the present invention has a plurality of spaced-apart bumps 11 with gaps 12 between the bumps 11, so that when the buffer strips 10 are bent toward one side of the bumps 11 Each of the bumps 11 reduces the amount of compression due to the gap 12 therebetween without touching the pressing, thereby avoiding unevenness of the surface of the cushion strip 10 during the bending process, and further causing the panel to easily slide and break when the panel is assembled.

In summary, the present invention can prevent scratches and abrasions of the display panel and the plastic frame from colliding with each other during assembly by transmitting the technical features of the buffer strip on the edge of the display panel. In addition, the buffer strip can increase the strength of the edge of the display panel, so that the display panel can avoid irregular deformation or cracking during the bending operation, thereby improving the production yield and reducing the manufacturing cost.

In addition, when the buffer strip is bent toward one side of the protruding block, each of the bumps reduces the amount of compression due to the gap therebetween without touching the pressing, thereby avoiding the unevenness of the surface of the buffer strip during the bending process. Further, the panel is easily slid and fragmented when the panel is assembled.

Furthermore, the concave curved surface of the plastic frame of the present invention has an arc curved surface shape compared with the conventional plastic frame, so that the display panel and the plastic frame do not have mutual interaction during the assembly process. The problem of interference.
