When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
In one embodiment, the curved display module of the present invention, as shown in fig. 1, includes a curved cover plate 100, an elastic rubber frame 200 and a display module 300; the curved cover plate 100 is a convex curved cover plate 100, that is, the curved surface of the curved cover plate 100 protrudes toward the observation side, the structure of the elastic rubber frame 200 is as shown in fig. 2, the surface of the elastic rubber frame 200 close to the curved cover plate 100 is also a convex curved surface, and the elastic rubber frame includes an inner wall 250, an outer wall 260, a top surface 270 and a bottom surface 280. The display module 300 has a visible area 320 and a peripheral area 330, and the curved cover plate 100 is provided with an ink layer 130 on a surface close to the display module 300 corresponding to the peripheral area 330. As shown in fig. 1, the elastic rubber frame 200 is tightly disposed between the curved cover plate 100 and the display module 300, the inner wall 250 of the elastic rubber frame 200 has a first compression amount, and the outer wall 260 has a second compression amount. The first compression amount is a compression deformation amount of the inner wall 250 of the elastic rubber frame 200 after the elastic rubber frame 200 is sandwiched between the display module 300 and the curved cover plate 100, and the second compression amount is a compression deformation amount of the outer wall 260 of the elastic rubber frame 200. In the embodiment shown in fig. 1, since the curved surface of the curved cover plate 100 protrudes toward the viewing side, when the elastic rubber frame 200 is sandwiched between the display module 300 and the curved cover plate 100, the inner wall 250 of the elastic rubber frame 200 is subjected to a smaller pressing force than the outer wall 260, and thus, the first compression amount is smaller than the second compression amount. After the elastic rubber frame 200 is tightly pressed between the curved cover plate 100 and the display module 300, the top surface 270 of the elastic rubber frame 200 is attached to the curved cover plate 100, and the bottom surface 280 is attached to the display module 300, so that the elastic rubber frame 200 can seal the gap between the curved cover plate 100 and the display module 300.

As shown in fig. 1 and 2, the accommodating space 210 is disposed in the elastic rubber frame 200, and when the elastic rubber frame 200 is tightly disposed between the curved cover plate 100 and the display module 300, the accommodating space 210 is sealed by the curved cover plate 100 and the display module 300, so that the optically transparent adhesive 220 can be filled in the accommodating space 220, and the optically transparent adhesive 220 is filled in the accommodating space 210 to further bond the curved cover plate 100 and the display module 300 together. It can be understood that, as long as the elastic rubber frame 200 can be tightly pressed between the display module 300 and the curved cover plate 100, the elastic rubber frame 200 can seal the gap between the curved cover plate 100 and the display module 300. That is, in other embodiments, the curved cover plate 100 may not be fastened to the display module 300, for example, in one embodiment, the curved cover plate 100 has a heavier weight, and after the curved cover plate 100 is covered on the elastic rubber frame 200 and the display module 300, the curved cover plate 100 can tightly press the elastic rubber frame 200 between the display module 300 and the curved cover plate 100 by its own weight. Alternatively, in other embodiments, there may be other connection manners between the curved cover plate 100 and the display module 300, so that the elastic rubber frame 200 can be tightly pressed between the display module 300 and the curved cover plate 100.
In one embodiment, according to the display principle of the display module 300, the display module 300 may be an LCM module, which includes a backlight module as a backlight source of the display module 300 for providing light to the display module 300 and a liquid crystal layer functioning as a light valve for controlling the emission of the light from the backlight source by cooperating with the polarizer. In another embodiment, the display module 300 may be an organic light emitting display module, which is a self-light emitting display module, and may include a plurality of organic light emitting diodes for emitting light, the organic light emitting diodes including an anode, a cathode, and an organic light emitting layer between the anode and the cathode.
In addition, in one embodiment, a top view structure of the elastic rubber frame 200 disposed on the display module 300 is shown in fig. 3 and 4. The display module 300 comprises a visible area 320 and a peripheral area 330, the visible area 320 is located in the central area of the display module 300, the peripheral area 330 surrounds the visible area 320 and is located in the edge-leaning area of the display module 300, and the projection position of the elastic rubber frame 200 on the display module 300 is located in the peripheral area 330; the distance between the inner wall 250 of the elastic rubber frame 200 and the visible area 320 at different positions is different, the elastic rubber frame 200 is provided with an opening 230, the minimum distance from the setting position of the opening 230 to the visible area is greater than the minimum distance from any position on the elastic rubber frame to the visible area, and the opening 230 is used for pouring the optical transparent rubber 220 and exhausting air during glue pouring.
In a specific embodiment, when the outer shape of the elastic rubber frame 200 is rectangular, the projection outline shape of the inner wall 250 of the elastic rubber frame 200 on the display module 300 is non-rectangular. For example, in one embodiment, the outer shape of the elastic rubber frame 200 is rectangular, and the projection outline of the inner wall 250 of the elastic rubber frame 200 on the display module 300 is arc-shaped, as shown in fig. 3 and 4, respectively. In the embodiment shown in fig. 3, the elastic rubber frame 200 is shaped as a concave arc, four frames 240 of the elastic rubber frame 200 are all concave away from the direction of the visible area 320, the minimum distance between the inner wall 250 at the center of the frame 240 and the visible area 320 is the largest, the maximum distance is D1, the minimum distance between the inner wall 250 at the corner of the elastic rubber frame 200 and the visible area 320 is the smallest, and the minimum distance is D2. Therefore, in the embodiment shown in fig. 3, the opening 230 is opened at the central position of the frame 240 to facilitate filling and exhausting the accommodating space 210 in the elastic rubber frame 200. It can be understood that, in the embodiment shown in fig. 3, if the opening 230 is opened at the corner of the elastic glue frame 200, air bubbles will accumulate at the center of the elastic glue frame 200 and cannot be discharged during the glue filling process, so that the reflection phenomenon between the optically transparent glue 220 and the air bubble interface is serious, and the visual effect is affected.
In the embodiment shown in fig. 4, the projection profile of the inner wall 250 of the elastic rubber frame 200 on the display module 300 is a convex arc, the four frames 240 of the elastic rubber frame 200 are all convex toward the direction of the visible region 320, the minimum distance between the inner wall 250 at the center of the frames 240 and the visible region 320 is the minimum, the minimum distance is D2, the minimum distance between the inner wall 250 at the corner of the elastic rubber frame 200 and the visible region 320 is the maximum, and the maximum distance is D1. Therefore, in the embodiment shown in fig. 4, the opening 230 is formed at the corner of the elastic rubber frame 200 to facilitate filling and exhausting the accommodating space 210 in the elastic rubber frame 200. It should be noted that, in the embodiment shown in fig. 2, the opening 230 is disposed at the center of the frame 240 of the elastic rubber frame 200, and the opening 230 is embedded in the frame body of the frame 240, and the frame 240 is not broken at the opening 230. It is understood that in other embodiments, as shown in fig. 3 and 4, the frame 240 may also be broken at the opening 230.
In another embodiment, as shown in fig. 5, the external shape of the elastic rubber frame 200 is rectangular, the projection profile of the inner wall 250 of the elastic rubber frame 200 on the display module 300 is trapezoidal, the inner wall 250 of one of the four frames 240 of the elastic rubber frame 200 inclines towards the direction close to the accommodating space 210, and the minimum distance from the left end of the frame 240 to the visible area 320 is greater than the minimum distance from any position on the elastic rubber frame 100 to the visible area 320, so that the opening is embedded in the left end frame of the inclined frame 240, and the opening is not shown in the top view structure shown in fig. 5. In yet another embodiment, as shown in fig. 6, the elastic rubber frame 200 has a rectangular outer shape, the inner wall 250 of the elastic rubber frame 200 has a wavy projection profile on the display module 300, the inner wall 250 of one of the four frames 240 of the elastic rubber frame 200 has a wavy projection profile on the display module 300, the minimum distances between the inner walls 250 and the visible regions 320 at different positions of the frame 240 are different, the opening is formed at the position where the inner wall 250 of the elastic rubber frame 200 has the largest distance from the visible regions 320, and the opening is embedded in the frame of the frame 240, so the opening is not shown in the top view structure shown in fig. 6. It should be noted that, in the embodiments shown in fig. 3 to fig. 6, the outer shape of the rubber frame is rectangular, and it is understood that, in other embodiments, the outer shape of the rubber frame may also be circular arc.
It should be noted that, when the projection profile of the inner wall 250 of the elastic rubber frame 200 on the display module 300 is a convex arc, as shown in the embodiment shown in fig. 4, the distance between the inner wall 250 and the visible area 320 at the corners of the elastic rubber frame 200 is the largest, a frame 240 protruding toward the visible area 320 exists between two corners of the elastic rubber frame 200, and if an opening 230 is only disposed at one corner of the elastic rubber frame 200, the remaining three corners are not smoothly exhausted during the glue filling process, therefore, in the embodiment shown in fig. 4, openings 230 are disposed at two adjacent corners of the frame rubber, so as to conveniently fill and exhaust the accommodating space 210 in the elastic rubber frame 200, and avoid accumulation of bubbles in the elastic rubber frame 200 and influence on the visual effect.
It should be noted that the shape of the elastic rubber frame 200 corresponds to the shape of the curved cover plate 100, as shown in fig. 1, when the curved cover plate 100 is a convex curved cover plate 100, the structure of the elastic rubber frame 200 is as shown in fig. 2, and the surface of the elastic rubber frame 200 near the curved cover plate 100 is a convex curved surface. It can be understood that, when the curved cover plate 100 is a concave curved cover plate 100, as shown in fig. 7, a side surface of the elastic rubber frame 200 close to the curved cover plate 100 is a concave curved surface, i.e., the curved surface of the curved cover plate 100 is recessed toward the display module 300. In addition, in the embodiment shown in fig. 7, the inner wall 250 of the elastic rubber frame 200 has a first compression amount, the outer wall 260 has a second compression amount, and since the curved surface of the curved cover plate 100 is recessed toward the display module 300, when the elastic rubber frame 200 is sandwiched between the display module 300 and the curved cover plate 100, the inner wall 250 of the elastic rubber frame 200 is subjected to a larger pressing force than the outer wall 260, and thus, the first compression amount is greater than the second compression amount. After the elastic rubber frame 200 is tightly pressed between the curved cover plate 100 and the display module 300, the top surface 270 of the elastic rubber frame 200 is attached to the curved cover plate 100, and the bottom surface 280 is attached to the display module 300, so that the elastic rubber frame 200 can seal the gap between the curved cover plate 100 and the display module 300.
In one embodiment, the shape of the elastomeric bezel 200 is designed according to Snell's law and the distance between the curved cover 100 and the display module 300. specifically, as shown in FIG. 1, the distance D from the viewing area 320 to the inner wall 250 of the elastomeric bezel 200 is calculated according to the height H of the inner wall 250 of the elastomeric bezel 200 and Snell's law, thereby obtaining the shape of the elastomeric bezel 200. to better illustrate the relationship between the height H of the inner wall 250 of the elastomeric bezel and the distance D from the viewing area 320 to the inner wall 250 of the elastomeric bezel 200, as shown in FIG. 8, in the embodiment shown in FIG. 8, the display module comprises a flat cover 120 and a display module 300, the display module 300 comprises an LCD device 360, a polarizer 350 and a frame 310, the polarizer 350 is disposed above the LCD device 360, one end of the LCD device 360 and the polarizer 350 is covered by the frame 310, the elastomeric bezel 200 is disposed between the frame 310 and the flat cover 120, the frame 200 is filled with an optically clear adhesive 220, the frame 310 comprises an upper plate 312, a side plate 313 and a lower plate 314 connected in that the upper plate 312 is lapped over the upper plate 350, the optical cover plate 312 is used for preventing the optical clear adhesive sealant 35V from penetrating into the display module 300, the display module is used for preventing the optical clear adhesive sealant from penetrating into the display module 300, the display module from the viewing angle of the display module, the display module 300, the display module:
it should be noted that, in the structure shown in fig. 8, for convenience of representing the dimensional relationship in the above formula (1), the cover plate adopts the planar cover plate 120, it is understood that the dimensional relationship in the above formula (1) also satisfies the case when the cover plate is the curved cover plate 100, the angle α is the interface refraction visual angle in the above formula (1), and the interface includes the contact surface between the curved cover plate 100 and the optical transparent adhesive, and the contact surface between the curved cover plate 100 and the air.
In addition, in the embodiment shown in fig. 8, one end of the polarizer 350 is covered by the frame 310, and it is understood that in other embodiments, the polarizer 350 may also be disposed above the LCD assembly 360 away from the frame 310, that is, the upper plate 312 of the frame 310 directly overlaps the LCD assembly, the overlapping end of the upper plate 312 is coated with the RTV sealant 340, and the RTV sealant 340 is used to seal the display module 300, so as to prevent the optically transparent adhesive 220 from penetrating into the display module 300 during the adhesive filling process.
In one embodiment, the elastic rubber frame 200 is made of compressible plastic material by injection molding, and the material of the elastic rubber frame 200 is silicone resin; alternatively, the elastic frame 200 is made of a polymer material which does not contain N, P, S elements in its molecular structure and can resist a high temperature of 95 °, such as PC plastic or ABS plastic. Compared with common plastic, the elastic rubber frame 200 has better material formability, the same flowing length and can be made thinner. Therefore, the elastic rubber frame 200 can be formed without being limited by the injection capability of a general injection molding device (the injection capability refers to the length of the injection molding device that can be filled and formed for different materials and different molding thicknesses), and the molding size of the elastic rubber frame 200 can be made thinner. As shown in fig. 3, the width w of the elastic rubber frame 200 is a variable value, and varies with the curvature and shape of the curved cover plate, the distance between the cover plate and the display module, and the variation of the detection viewing angle, and the width w of the elastic rubber frame 200 can reach the size range that cannot be reached by common plastics, in one embodiment, the width w of the elastic rubber frame 200 ranges from 0.6mm to 4mm, when the width w of the elastic rubber frame 200 reaches the minimum value, the distance D between the visible region 320 of the display module 300 and the inner wall 250 of the elastic rubber frame 200 can reach the maximum value, according to the formula (1), it can be concluded that when the distance D between the visible region 320 of the display module 300 and the inner wall 250 of the elastic rubber frame 200 is maximized, the interface refraction angle is larger, so that the visual effect of the curved display module is better.
In addition, as shown in fig. 1, the minimum distance between different positions of the curved cover plate 100 and the display module 300 is different. In the embodiment shown in fig. 1, after the elastic rubber frame 200 is tightly pressed and disposed between the display module 300 and the curved cover plate 100, the height of the outer wall 260 of the elastic rubber frame is L, and the minimum distance between the edge of the curved cover plate 100 and the display module 300 is equal to the height L of the outer wall 260 of the elastic rubber frame, because the thickness of the elastic rubber frame 200 can be thinner, in a specific embodiment, the height range of the outer wall 260 of the elastic rubber frame is less than or equal to 25 micrometers. Therefore, the minimum distance L between the edge of the curved cover plate 100 and the display module 300 can be minimized, i.e., the distance L can be less than or equal to 25 μm. When the minimum distance L between the curved cover plate 100 and the display module 300 is minimized, the distance between the curved cover plate 100 and the display module 300 is correspondingly minimized under the condition that the curvature of the curved cover plate 100 is not changed, and therefore, the usage amount of the optically transparent adhesive 220 can be saved. In addition, in the embodiment shown in fig. 7, when the curved cover plate 100 is a concave curved cover plate 100, the minimum vertical distance L between the curved cover plate 100 and the display module 300 can be minimized, i.e., the distance L is less than or equal to 25 micrometers.
According to the curved surface display module, the elastic rubber frame 200 is tightly arranged between the curved surface cover plate 100 and the display module 300, the projection position of the elastic rubber frame 200 is positioned in the peripheral area 330 of the display module 300, and the inner wall 250 and the outer wall 260 of the elastic rubber frame 200 respectively have the first compression amount and the second compression amount, so that the top surface 270 and the bottom surface 280 of the elastic rubber frame 200 are respectively attached to the curved surface cover plate 100 and the display module 300, and the elastic rubber frame 200 can seal the gap between the curved surface cover plate 100 and the display module 300, so that the double-sided adhesive and RTV (room temperature vulcanized) sealant can be omitted in the assembly and attachment process of the curved surface display module, all parts can be tightly attached together, the assembly and attachment process of the curved surface display module is simplified, the assembly and attachment cost is reduced, and the product yield is improved.
