As the duty cycle of the display screen increases, the overall screen product increases. On the market, the difference in the appearance of various products is gradually reduced. Currently, integrated display products are increasingly popular with consumers, and users have also made strong demands for integration of display devices.
Based on this, an embodiment of the present application provides a display device, as shown in fig. 1, fig. 1 is one of partial enlarged views of a display device 100 provided in an embodiment of the present application, where the display device 100 may include a display panel 10, a middle frame 20, a back plate 30, and an appearance film 40.
As shown in fig. 1, the display panel 10 has a display surface 11 and a back surface 12 provided opposite to the display surface 11. The display surface 11 of the display panel 10 can be used for displaying pictures. The display panel 10 is generally rectangular in shape and has a rectangular display surface.
In actual use, both sides in the width direction of the display panel 10 may be referred to as a top side and a bottom side of the display device 100, respectively, and both sides in the length direction of the display panel 10 may be referred to as a left side and a right side of the display device 100, respectively. Here, the partial enlarged view shown in fig. 1 is a partial enlarged view at the left or right side of the display device 100.
In addition, the display panel 10 may be a different type of display panel. The display panel 10 may be a liquid crystal display panel, for example, in which a plurality of sub-pixels are distributed. The sub-pixel is the minimum imaging unit of the liquid crystal display panel, and a plurality of sub-pixels which emit different light rays and are adjacent in sequence can form a pixel. For example, sequentially adjacent red (R), green (G), and blue (B) sub-pixels constitute one pixel. In this case, the purpose of adjusting the display color of the pixel can be achieved by adjusting the ratio of R, G, B light rays in different pixels.
The middle frame 20 may be disposed around one circumference of the display panel 10. Since the middle frame 20 is disposed around a circumference of the display panel 10, the middle frame 20 may be coupled to a circumference of the rear surface 12 of the display panel 10, thereby enabling the middle frame 20 to support and fix the display panel 10.
It will be appreciated that although fig. 1 shows a schematic structural view of only one side of the display panel 10, in actual use, the middle frame 20 is disposed around the display panel 10, so that each position of the display panel 10 can be fixed by the middle frame 20.
With continued reference to fig. 1, a portion of the middle frame 20 is located on the peripheral side of the display panel 10. The other part of the middle frame 20 is positioned at the side of the back surface 12 of the display panel 10, and is connected with the back surface 12 for supporting and fixing the display panel 10. In this way, the peripheral position of the back surface 12 of the display panel 10 can be connected to the portion of the middle frame 20 on the side of the back surface 12 of the display panel 10.
In order to connect the middle frame 20 with the back 12 of the display panel 10, the display device 100 further includes an adhesive member 50, as shown in fig. 1, and the adhesive member 50 is disposed between the back 12 and the middle frame 20. The rear surface 12 of the display panel 10 and the middle frame 20 may be bonded together by the adhesive 50. By way of example, the adhesive 50 may be double-sided foam.
As shown in fig. 1, the back plate 30 is located on the side of the back surface 12 of the display panel 10 and is connected to the middle frame 20. The back plate 30 and the display panel 10 may define a mounting cavity therebetween, and provide a mounting space for related components of the display device 100.
When the display panel 10 is a liquid crystal display panel, as shown in fig. 2, fig. 2 is a second enlarged view of a portion of the display device 100 according to the embodiment of the application, the display device 100 may further include a light guide plate 61, an optical film 62, and a backlight 70. The light guide plate 61 and the optical film 62 are positioned between the display panel 10 and the back plate 30.
The light guide plate 61 may be used to guide light emitted from the backlight 70 to the rear surface 12 of the display panel 10 so that the display panel 10 can display a picture. As shown in fig. 2, the backlight 70 may be provided at a side surface of the light guide plate 61 (side-entrance backlight) to emit light from the side surface of the light guide plate 61. The light enters the light guide plate 61 and is totally reflected, and propagates toward the other side. Meanwhile, during the propagation of the light inside the light guide plate 61, the total reflection of a part of the light is broken, and the light is emitted from the surface of the light guide plate 61 on the side close to the display panel 10.
The optical film 62 may be positioned at a side of the light guide plate 61 near the display panel 10. The optical film 62 can process the light emitted from the light guide plate 61 to improve the display effect of the display screen. For example, the optical film 62 may include a brightness enhancing sheet and a prism sheet to enhance brightness and uniformity of a display screen.
In addition, in order to enhance the light utilization efficiency, as shown in fig. 2, the display device 100 may further include a reflective sheet 63, where the reflective sheet 63 is located at a side of the light guide plate 61 away from the optical film 62. In this way, when the light is transmitted to the side of the reflective sheet 63, the light is reflected by the reflective sheet 63 and then emitted from the other side of the light guide plate 61 to the display panel 10, so as to improve the light utilization efficiency.
Of course, in other embodiments, the display device 100 may also include a diffusion plate (not shown), where the backlight 70 may be a direct type backlight, and the backlight 70 may be located on a side of the diffusion plate away from the display panel 10. The light emitted from the backlight 70 is diffused by the diffusion plate to form a surface light source.
In order to integrate the display device 100, the industrial appearance of the display device 100 is improved, and as shown in fig. 1, the appearance film 40 covers the display surface 11 of the display panel 10 and a portion of the middle frame 20 located on the peripheral side of the display panel 10.
Therefore, the portion of the middle frame 20 located on the periphery of the display panel 10 is shielded by the appearance film 40, so that the display device 100 integrates the appearance of the display device 100 from the side of the display surface 11, the appearance effect of the display device 100 is improved, and the market competitiveness of the display device 100 is improved.
In order for the appearance film 40 not to affect the display effect of the display device 100, in some embodiments, as shown in fig. 1, the appearance film 40 may include a transmissive portion 41 and a shielding portion 42. The vertical projection of the transmission portion 41 on the display surface 11 overlaps the display surface 11, and the transmission portion 41 is a transparent film for transmitting light emitted from the display surface 11. Thus, the light emitted from the display surface 11 can enter the human eye through the transmission portion 41, and the user can see the display screen.
It is understood that the transmissive part 41 may be made of a material having a high transmittance. By way of example, the transmissive part 41 may be made of a material having a transmittance of more than 85%. For example, the transmissive part 41 may be made of a polyethylene terephthalate (Polyethylene terephthalate, PET) material. The PET material has high transmittance, and can ensure that as much light as possible emitted from the display surface 11 passes through the transmission portion 41.
As shown in fig. 3, fig. 3 is a front view of the display surface 11 of the display device 100 shown in fig. 1, and the shielding portion 42 is located at the periphery of the transmitting portion 41. The shielding portion 42 is a black film for shielding the middle frame 20 (fig. 1).
As a result, as shown in fig. 1, the middle frame 20 is blocked by the blocking portion 42, and since the blocking portion 42 is a black film, the viewer cannot see the middle frame 20 after the blocking portion 42 from the side where the display surface 11 is located, and the overall appearance of the display device 100 is improved.
The shielding portion 42 may be made into a black film by a silk screen technique. Illustratively, the transmissive portion 41 and the shielding portion 42 are integrally formed of a PET material, and then a black film can be formed in a corresponding region using a silk screen technique.
In order to prevent collision between the portion of the middle frame 20 located at the peripheral side of the display panel 10 and the display panel 10, damage is caused to the display panel 10. As shown in fig. 1, in some embodiments, a buffer gap is provided between a portion of the middle frame 20 located at the peripheral side of the display panel 10 and the display panel 10. The display device 100 further includes a buffer 80. The buffer 80 is disposed in the buffer gap for buffering to prevent the middle frame 20 from colliding with the display panel 10.
Therefore, the middle frame 20 and the display panel 10 are buffered through the buffer piece 80, so that the middle frame 20 is prevented from directly colliding with the display panel 10, and the display panel 10 is prevented from being damaged. It will be appreciated that the cushioning members 80 may be made of a resilient material to provide better cushioning. For example, the buffer 80 may be made of a silicone material.
Further, it is understood that the buffer 80 may be provided around the circumference of the display panel 10. In this way, the portion of the display panel 10 on the peripheral side can be separated from the middle frame 20 by the buffer 80, thereby better protecting the display panel 10 from being damaged by the middle frame 20.
As shown in fig. 1, in order to further enhance the integration of the display device 100, in some embodiments, the appearance film 40 extends from both sides of the display panel 10 to a side of the back plate 30 away from the display panel 10 in the first direction X, and is connected to the middle frame 20 or the back plate 30. Thus, the appearance film 40 surrounds the middle frames 20 on both sides in the first direction X, and both sides of the display device 100 are integrally designed by the appearance film 40, thereby improving the integration of the appearance of the display device 100.
It will be appreciated that although fig. 1 shows only a schematic structure in which the appearance film 40 extends from one side of the display panel 10 to the side of the back plate 30 away from the display panel 10, the appearance film 40 also extends to the side of the back plate 30 away from the display panel 10 on the other side of the display panel 10 in the same manner.
Further, it is understood that the appearance film 40 may extend from different directions to a side of the back plate 30 remote from the display panel 10. As shown in fig. 1, fig. 1 is a partially enlarged view of the left or right side of the display device 100. At this time, the first direction X is the longitudinal direction of the display panel 10. In this way, the center 20 on both the left and right sides of the display device 100 can be covered along the first direction X, and integration of the display device 100 in the left and right directions is achieved.
It will be appreciated that the appearance membrane 40 may be made of a flexible material. Illustratively, as noted above, the appearance film 40 may be made of a PET material that is flexible and capable of bending. Meanwhile, the transmittance of the PET material is high, and the display effect of the display picture can be ensured.
The appearance film 40 may be disposed in other manners, and in other embodiments, the appearance film 40 may be disposed on the side of the display surface 11 of the display panel 10 to cover the display panel 10 and the middle frame 20. At this time, the appearance film 40 is located only on the display surface 11 side of the display panel 10, and covers the display panel 10 and the peripheral middle frame 20 from only the display surface 11 side, thereby integrating the display device 100 on the display surface 11 side.
Based on the scheme shown in fig. 1, in order to facilitate the connection of the exterior film 40 to the back plate 30 or the middle frame 20, as shown in fig. 1, the display device 100 may further include a support sheet 90 in some embodiments. The support sheet 90 is bonded to a portion of the appearance film 40 on the side of the back surface 12 of the display panel 10. The support sheet 90 is positioned on the side of the appearance film 40 adjacent to the back plate 30, and is bonded to the middle frame 20 or the back plate 30.
The exterior film 40 is connected to the middle frame 20 or the back plate 30 through the support sheet 90. In this way, before fixing the exterior film 40, the exterior film 40 may be bonded to the support sheet 90, and then the exterior film 40 may be fixed by bonding between the support sheet 90 and the middle frame 20 or the back plate 30.
When the appearance film 40 is directly bonded to the middle frame 20 or the back plate 30, the bonding area is large, bubbles are easily generated in the bonding process, and the bonding yield is low. Therefore, when the support sheet 90 and the appearance film 40 are bonded in advance and a problem of poor adhesion occurs between the support sheet 90 and the appearance film 40, repair can be performed in advance, and the adhesion yield can be ensured.
In this way, the supporting sheet 90 is connected with the middle frame 20 or the back plate 30, so that the problem that the bonding difficulty is high and bubbles are easy to occur due to the fact that the appearance film 40 is directly bonded with the middle frame 20 or the back plate 30 is avoided, and the overall bonding yield of the appearance film 40 is improved.
The support sheet 90 and the appearance film 40 may be bonded by various means, and as illustrated in fig. 1, the support sheet 90 and the appearance film 40 may be bonded together by the bonding member 50, for example. In bonding the exterior film 40 and the support sheet 90, the support sheet 90 is bonded to one side of the bonding member 50, and then the exterior film 40 is bonded to the other side of the bonding member 50 to complete bonding. The adhesive 50 may be double-sided foam or the adhesive may be applied directly to the support sheet 90 to form the adhesive 50.
The support sheet 90 may be made of a hard material. Illustratively, the support sheet 90 may be a Polycarbonate (PC) sheet. The hard PC sheet is pre-adhered to the appearance film 40, and then the appearance film 40 is fixed by the connection between the hard PC sheet and the backboard 30 or the middle frame 20, so that the adhesion difficulty of the appearance film 40 is reduced, and the lamination yield of the appearance film 40 is improved. Of course, the supporting plate 90 may be made of other hard materials, which may be selected according to practical needs, and will not be further described herein.
In some embodiments, as shown in fig. 1, the adhesive 50 may also be located between the display surface 11 of the display panel 10 and the appearance film 40, and the display surface 11 of the display panel 10 and the appearance film 40 are adhered by the adhesive 50.
The display panel 10 and the appearance film 40 are adhered by the adhesive piece 50, so that the adhesion between the appearance film 40 and the display panel 10 can be ensured, the flatness of the appearance film 40 is ensured, and the display effect of a display picture is further ensured.
It should be understood that, as shown in fig. 4, fig. 4 is a schematic structural diagram of a side of the display panel 10 near the display surface 11, the display surface 11 may include a display area 111 and a non-display area 112 located at a periphery of the display area 111, and the adhesive 50 may be adhered to the non-display area 112 of the display surface 11, so as to avoid the adhesive 50 from affecting a display effect of the display screen.
As shown in fig. 4, the number of the adhesive members 50 adhered to the non-display area 112 may be plural. A plurality of adhesive members 50 are spaced around the periphery of the display area 111. As illustrated in fig. 4, the display area 111 is rectangular, and the number of the adhesive members 50 is four, which are disposed on four sides of the display area 111, respectively.
Of course, in other embodiments, as shown in fig. 5, fig. 5 is a schematic view of another structure of the display panel 10 near the display surface 11, and the adhesive member 50 adhered to the non-display area 112 may be disposed around the display area 111. In this way, the adhesion between the display panel 10 (fig. 2) and the appearance film 40 (fig. 2) is more secure.
In addition, in the process of assembling the display device 100, the display panel 10 and the exterior film 40 are first adhered together by the adhesive 50, and then the display panel 10 and the middle frame 20 are assembled. Thus, the appearance film 40 and the display panel 10 are bonded in advance through the bonding piece 50, so that the bonding of the appearance film 40 and the display panel is more convenient, the repair is convenient, and the problem that the appearance film 40 is difficult to overhaul after bubbles appear in the process of bonding the display panel 10 and the middle frame 20 after the assembly can be avoided.
Of course, the display panel 10 and the adhesive 50 may be kept flat by adhering the exterior film 40 to the middle frame 20 or the back plate 30 without adhering them. At this time, there is no adhesive relation between the display panel 10 and the appearance film 40, and the separation of the appearance film 40 and the display panel 10 is more convenient, thereby facilitating the maintenance and replacement of the appearance film 40.
As shown in fig. 6, fig. 6 is a schematic view showing the bonding positions of the display panel 10, the appearance film 40 and the supporting sheet 90, and the display panel 10 and the supporting sheet 90 may be pre-adhered to one side of the appearance film 40 to form a whole. Then, the whole is assembled with the backlight module formed by assembling the middle frame 20 (fig. 2) and the back plate 30 (fig. 2) together, so that the assembly of the display device 100 can be completed.
In some embodiments, as shown in fig. 6, a side of the support sheet 90 away from the display panel 10 may be flush with a side of the appearance film 40 in the first direction X. In this way, along the first direction X, the supporting sheet 90 is located at the edge positions of the two sides of the appearance film 40, and is adhered to the edge positions of the two sides of the appearance film 40, so that the appearance film 40 is not easy to deform, and the situation of rolling and warping is avoided.
Similarly, as shown in fig. 6, in the second direction Y, the side edges of both sides of the support sheet 90 may be flush with the side edges of both sides of the appearance film 40, so that the corresponding positions in the side edges of both sides of the appearance film 40 are less likely to suffer from curling and warping.
In some embodiments, as shown in fig. 1, the middle frame 20 may include two first middle frames 21. Along the first direction X, two first middle frames 21 are respectively located at two sides of the display panel 10. A part of the first middle frame 21 is located on the peripheral side of the display panel 10, and the other part is located on the side of the back surface 12 of the display panel 10, and is connected to the display panel 10. In this way, when fixing the display panel 10, the two first middle frames 21 can be respectively connected to corresponding positions on the back surface 12 of the display panel 10, and the display panel 10 can be fixed.
As shown in fig. 1, along the first direction X, a surface of the first middle frame 21 on a side away from the display panel 10 is an arc surface. The portions of the appearance film 40 extending to both sides of the display panel 10 along the first direction X are attached to the arc surfaces.
Because the surface of the first middle frame 21 far away from the side of the display panel 10 is a cambered surface, the appearance film 40 is easier to attach to the surface, so that the appearance film 40 is better attached, and the attaching effect of the appearance film 40 is improved. Meanwhile, two sides of the whole display device 100 can form an arc-shaped appearance, so that the industrial appearance of the display device 100 is improved, and the market competitiveness of the product is improved. Of course, the surface of the first middle frame 21 on the side away from the display panel 10 may be a flat surface, and the appearance film 40 may be bonded to the flat surface.
With continued reference to fig. 1, the first middle frame 21 may include a first connection portion 211, a second connection portion 212, and a third connection portion 213. Along the first direction X, a surface of the first connection portion 211 on a side away from the display panel 10 is an arc surface. The cambered surface facilitates the lamination of the appearance film, so that the positions of the appearance film 40 on the two sides of the display panel 10 have better lamination effect.
The second connection portion 212 is connected to the first connection portion 211, is located on the side of the back surface 12 of the display panel 10, and is connected to the back surface 12 of the display panel 10. The connection between the display panel 10 and the first middle frame is achieved through the second connection portion 212. As shown in fig. 1, the second connection portion 212 and the back surface 12 of the display panel 10 are bonded to each other by the adhesive 50.
The third connecting portion 213 is connected to the first connecting portion 211, is located on a side of the second connecting portion 212 away from the display panel 10, and is spaced apart from the second connecting portion 212. Thereby, the interval between the second connection portion 212 and the third connection portion 213 forms a mounting groove. As shown in fig. 1, a portion of the optical film 62 may be positioned within the mounting groove, thereby providing a certain limit to the optical film 62 and preventing displacement of the optical film 62.
With continued reference to fig. 1, a portion of the third connection portion 213 may be located at a side of the back plate 30 remote from the display panel 10. The support sheet 90 may be adhered to the third connection portion 213. In this way, by the connection between the third connection portion 213 and the support sheet 90, the fitting fixation of the exterior film 40 is achieved, so that the whole of the exterior film 40 can be relatively fixed.
To enable the perimeter of the display panel 10 to be connected to the middle frame 20, in some embodiments, as shown in fig. 2, the middle frame 20 may further include a second middle frame 22. Along the second direction Y, the second middle frame 22 is located at one side of the display panel 10. A part of the second middle frame 22 is located on the peripheral side of the display panel 10, and the other part is located on the side of the back surface of the display panel 10, and is connected to the back surface 12 of the display panel 10.
