Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display device. Background Art

[0002] With the rapid development of display technology, the demand for display screens is getting higher and higher, and narrow or ultra-narrow borders have become a development trend. In order to ensure the stability and reliability of the display screen, middle frame glue is usually used to bond the display module and the middle frame.

[0003] At present, the assembly process of narrow-frame display devices is generally: first apply the middle frame glue on the supporting surface of the middle frame, and then press the display module onto the middle frame. Since the middle frame glue has a certain fluidity before curing, the middle frame glue is squeezed by the surface structure of the display module and easily overflows to the gap between the middle frame and the display module, and adheres to the colloid in the display module. When the middle frame is subjected to external force, the colloid will be impacted by the middle frame, which is easy to cause visible bubbles in the colloid and other problems, thereby affecting the display effect. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a display device to prevent bubbles from being generated in the colloid when the middle frame is subjected to external force.

[0005] An embodiment of the present application discloses a display device, which includes a first optical device, a second optical device, a middle frame and a barrier. The second optical device is arranged opposite to the first optical device, and an edge of the second optical device exceeds an edge of the first optical device; a portion of the second optical device overlapping with the first optical device is a first overlapping portion, and the first overlapping portion and the first optical device are bonded by colloid; the first optical device is arranged on a side of the second optical device close to the middle frame, a side of the middle frame facing the second optical device is a supporting surface, a portion of the second optical device overlapping with the supporting surface is a second overlapping portion, and the second overlapping portion is bonded to the supporting surface by middle frame glue; the barrier is arranged on a side of the second optical device facing the first optical device, located between the first overlapping portion and the second overlapping portion, and the barrier protrudes from the surface of the second optical device.

[0006] Optionally, the barrier is annular and is arranged around the first optical device; the barrier is arranged opposite to the inner side surface of the middle frame, and the distance between the barrier and the inner side surface of the middle frame is less than or equal to 0.2 mm.

[0007] Optionally, a groove is provided on the barrier, the opening of the groove faces the middle frame glue, and the groove is arranged on a side of the barrier close to the second optical device.

[0008] Optionally, the height of the groove is greater than the distance between the second optical device and the supporting surface.

[0009] Optionally, an extension groove is provided on the second overlapping portion, and an opening of the extension groove faces the supporting surface.

[0010] Optionally, one end of the extension groove is flush with an edge of the second optical device.

[0011] Optionally, a width of the extension groove on a side close to the support surface is smaller than a width of the extension groove on a side away from the support surface.

[0012] Optionally, the display device further includes a retaining wall, which is arranged on a side of the support surface close to the second overlapping portion and located at an end of the support surface facing the blocking member; the retaining wall is annular, arranged around the blocking member, and there is a gap between the retaining wall and the blocking member.

[0013] Optionally, a surface of the barrier away from the second optical device and a surface of the barrier away from the middle frame are both reflective surfaces.

[0014] Optionally, the first optical device includes a display panel, and the second optical device includes a cover plate; or, the first optical device includes an optical film, and the first optical device includes a display panel.

[0015] The beneficial effect of the embodiment of the present application is that by setting a barrier on the side of the second optical device facing the first optical device, when the second optical device is pressed onto the middle frame, the middle frame glue is squeezed by the second optical device, and even if it overflows in the direction of the first optical device, it will be blocked by the barrier between the first overlapping part and the second overlapping part, thereby preventing the middle frame glue from adhering to the colloid. After using the display device in the embodiment of the present application, when the middle frame is subjected to external force, the force will only be transmitted to the barrier through the middle frame glue, and will not be transmitted to the colloid, thereby avoiding the problem that the colloid is subjected to impact force, which in turn causes bubbles to be generated in the colloid, affecting the display effect.

DETAILED DESCRIPTION

[0028] It should be understood that the terms used herein, the specific structures and functional details disclosed are only for describing specific embodiments and are representative, but the present application can be implemented in many alternative forms and should not be construed as being limited to only the embodiments described herein.

[0029] In addition, unless otherwise clearly specified or limited, "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internally connected between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a display device, wherein the display device 10 includes a display module 20, a middle frame 31 and a back plate 32, wherein the middle frame 31 is connected to the back plate 32, and a step is formed on the top of the middle frame 31. The display module 20 includes a first optical device 22 and a second optical device 21, wherein the first optical device 22 and the second optical device 21 are arranged opposite to each other, and the first optical device 22 is arranged on a side of the second optical device 21 close to the middle frame 31, and the edge of the second optical device 21 exceeds the edge of the first optical device 22. The edge of the second optical device 21 is bonded and fixed to a side of the step with a lower terrain; wherein the first optical device 22 is located within the range surrounded by the middle frame 31 and does not contact the middle frame 31.

[0031] like Figure 1 As shown, in some embodiments, the display device 10 is an OLED (Organic Light Emitting Diode) display, in which case the first optical device 22 is an OLED display panel, and the second optical device 21 is a cover plate, which is located on the light-emitting side of the display panel. The cover plate is connected to the display panel through a colloid 24, and the edge of the cover plate is also bonded to the middle frame 31 through a middle frame glue 60.

[0032] Among them, the first optical device 22 includes a display function layer 221, a buffer layer 222 and a polarizing layer 223. The display function layer 221 refers to a film layer that can realize the display function, which may include a pixel driving circuit and a light-emitting device, etc. Among them, the display function layer 221, the buffer layer 222 and the polarizing layer 223 are stacked in sequence, and the polarizing layer 223 is connected to the cover plate through a colloid.

[0033] Furthermore, the display module 20 may further include a heat dissipation layer 23, and the back of the display function layer 221 is connected to the heat dissipation layer 23, and the heat dissipation layer 23 may be an opaque metal layer. In the above design, the heat dissipation layer 23 is located on the backlight side of the display function layer 221, and the heat dissipation layer 23 is used to dissipate the heat of the display function layer 221 to reduce the degree of heat generation of the display function layer 221. The heat dissipation layer 23 may be a heat dissipation fin, a metal sheet or other structure composed of heat-absorbing materials.

[0034] like Figure 2 As shown, in some embodiments, the display device 10 is an LCD (Liquid Crystal Display) display, in which case the first optical device 22 is an optical film 28, the second optical device 21 is a liquid crystal display panel, the optical film 28 is connected to the display panel through a colloid 24, and the edge of the display panel is also bonded to the middle frame 31 through a middle frame glue 60.

[0035] Among them, the second optical device 21 also includes an array substrate 27, a liquid crystal layer 26 and a color filter substrate 25. The array substrate 27 and the color filter substrate 25 are arranged in a box, and the liquid crystal layer 26 is located between the array substrate 27 and the color filter substrate 25. At this time, the array substrate 27 is connected to the first optical device 22 through the colloid 24.

[0036] In the embodiment of the present application, the portion of the second optical device 21 that overlaps with the first optical device 22 is the first overlapping portion 21a, and the first optical device 22 and the first overlapping portion 21a are bonded by the glue 24; the side of the middle frame 31 facing the second optical device 21 is the supporting surface 311, and the portion of the second optical device 21 that overlaps with the supporting surface 311 is the second overlapping portion 21b, and the second overlapping portion 21b and the supporting surface 311 are bonded by the middle frame glue 60. In addition, the display device 10 further includes a blocking member 40, which is disposed on the side of the second optical device 21 facing the first optical device 22, between the first overlapping portion 21a and the second overlapping portion 21b, and the blocking member 40 protrudes from the surface of the second optical device 21 and extends toward the back plate 32.

[0037] When the display device 10 is an OLED display, the barrier 40 is disposed on a side of the cover plate facing the display panel; when the display device 10 is an LCD display, the barrier 40 is disposed on a side of the array substrate 27 in the display panel facing the optical film 28 .

[0038] In the embodiment of the present application, a barrier 40 is provided on the side of the second optical device 21 facing the first optical device 22. In the process of pressing the second optical device 21 onto the middle frame 31, after the middle frame glue 60 is squeezed by the second optical device 21, even if it overflows toward the direction of the first optical device 22, it will be blocked by the barrier 40 between the first overlapping portion 21a and the second overlapping portion 21b, thereby preventing the middle frame glue 60 from adhering to the colloid 24. Moreover, since the barrier 40 is between the first overlapping portion 21a and the second overlapping portion 21b, the barrier 40 will not overlap with the middle frame 31, and will not contact with the middle frame 31, so that the distance between the second optical device 21 and the middle frame 31 will not increase, and the thickness of the display device 10 will not increase.

[0039] After adopting the display device 10 in the embodiment of the present application, when the middle frame 31 is subjected to external force, the force will only be transmitted to the blocking member 40 through the middle frame glue 60, and will not be transmitted to the colloid 24, thereby preventing the colloid 24 from being subjected to impact force, which in turn causes bubbles to be generated in the colloid 24 and affects the display effect.

[0040] In the embodiment of the present application, the colloid 24 is made of optical glue to avoid affecting the light transmittance.

[0041] like Figure 3 As shown, in the embodiment of the present application, the barrier 40 is a ring structure connected end to end, surrounding the first optical device 22 and the colloid 24 to prevent the middle frame glue 60 from overflowing from any position and contacting the colloid 24.

[0042] Furthermore, the barrier 40 extends below the support surface 311 of the middle frame 31, so that the inner side surface of the middle frame 31 is opposite to the outer side surface of the barrier 40. For the convenience of assembly, the distance between the outer side surface of the barrier 40 and the inner side surface of the middle frame 31 is less than or equal to 0.2 mm. Moreover, since the middle frame glue 60 is sticky, it will not flow into the gap within 0.2 mm, thereby preventing the middle frame glue 60 from dripping onto the back plate 32, so that the middle frame glue 60 will not be wasted.

[0043] Through the above design, the barrier 40 and the middle frame 31 cooperate with each other, so that the display module 20 can be easily aligned during the process of assembling the display module 20 onto the middle frame 31, thereby improving assembly efficiency and reducing assembly deviation. Moreover, after the display module 20 is assembled, since the barrier 40 is a ring structure connected end to end, and the gap between the barrier 40 and the middle frame 31 is very small, dust and liquid can be prevented from entering the interior of the display device 10, and combined with the sealing design of the middle frame glue 60, a double blocking effect is achieved.

[0044] In the embodiment of the present application, the barrier 40 and the second optical device 21 are an integral structure and are both made of glass or transparent plastic. This can avoid increasing the number of assembly steps due to the addition of the barrier 40 in the display device 10 and can also improve the stability between the barrier 40 and the second optical device 21.

[0045] Alternatively, the barrier 40 and the second optical device 21 are not an integral structure, and the barrier 40 is formed on the second optical device 21 by bonding, printing, or the like.

[0046] Moreover, on this basis, the barrier 40 is made of opaque material. With this design, the barrier 40 can not only prevent the middle frame glue 60 from overflowing and contacting the glue 24 , but also block light to prevent light leakage from the edge of the display device 10 .

[0047] Alternatively, on the basis that the barrier 40 and the second optical device 21 are not an integral structure, the barrier 40 is made of a reflective material, or a reflective material or a reflective film is applied to the inner side and the bottom of the barrier 40, so that the side of the barrier 40 away from the second optical device 21 and the side away from the middle frame 31 are both reflective surfaces. With this design, when the backlight or the first optical device 22 emits light, if the light shines on the barrier 40, the barrier 40 can reflect the light back, thereby improving the light utilization rate and facilitating the display brightness. Furthermore, the height of the barrier 40 can be increased to increase the area of ​​reflected light. For example, the height of the barrier 40 can be made half of the height of the middle frame 31, or even the height of the barrier 40 can be made as large as possible, so that the end of the barrier 40 abuts against the back plate 32. At this time, in addition to having the largest reflective area, the barrier 40 can also play a supporting role for the second optical device 21.

[0048] It should be noted that the height of the blocking member 40 and the height of the middle frame 31 refer to the size of the blocking member 40 and the size of the middle frame 31 in the distance direction between the second optical device 21 and the back plate 32 , respectively.

[0049] Alternatively, on the basis that the barrier 40 and the second optical device 21 are not an integral structure, the barrier 40 is made of a stress absorbing material, which may be rubber, silicone, etc. In the process of pressing the second optical device 21 onto the middle frame 31, the middle frame glue 60 is squeezed by the second optical device 21 and overflows in the direction of the first optical device 22 until it is blocked by the barrier 40. After the middle frame glue 60 is cured, the middle frame glue 60 is connected to the barrier 40. When the middle frame 31 is subjected to external force, the force will be transmitted to the barrier 40 along with the middle frame glue 60. At this time, since the barrier 40 is made of a stress absorbing material, the force transmitted to the barrier 40 by the middle frame glue 60 will be absorbed by the barrier 40, and the force will hardly continue to be transmitted in the direction of the colloid 24.

[0050] Moreover, since the colloid is prone to thermal expansion and contraction, even when the middle frame glue 60 expands due to heat and squeezes the barrier 40, only the squeezed side of the barrier 40 will be concave, and the colloid 24 will not be squeezed, and bubbles will not appear inside the colloid 24. Therefore, when the middle frame glue 60 expands due to heat, the barrier 40 made of stress absorbing material will not transmit the force to the colloid 24, effectively ensuring the display effect of the display device 10 when subjected to external forces or high temperatures.

[0051] It should be noted that when the barrier 40 is made of stress absorbing material, the barrier 40 can also have the function of blocking light or reflecting light at the same time. For example, black dye can be injected before the stress absorbing material is formed, and the barrier 40 can be specifically black rubber, which can simultaneously meet the effects of absorbing stress and blocking light, so that the barrier 40 can simultaneously have the triple effects of blocking the middle frame glue 60 from contacting the colloid 24, absorbing the force transmitted by the middle frame glue 60, and preventing light leakage from the edge of the display device 10, greatly improving the practical effect of the barrier 40. Similarly, if the barrier 40 is to have a reflective effect, reflective particles can be injected before the stress absorbing material is formed, or a reflective film layer can be directly coated on the surface of the stress absorbing material after it is formed, so that the barrier 40 can simultaneously have the triple effects of blocking the middle frame glue 60 from contacting the colloid 24, absorbing the force transmitted by the middle frame glue 60, and reflecting the backlight to improve the light utilization rate, which also greatly improves the practical effect of the barrier 40.

[0052] It should be noted that when the barrier 40 is made of stress absorbing material, the barrier 40 can directly contact the colloid 24. When the frame of the display device 10 is too small, resulting in a small spacing between the first overlapping portion 21a and the second overlapping portion 21b, in order to ensure the barrier 40's blocking effect on the middle frame glue 60, the barrier 40 can be completely filled in the gap between the first overlapping portion 21a and the second overlapping portion 21b, so that the two sides of the barrier 40 are in contact with the middle frame glue 60 and the colloid 24 respectively. At this time, since the barrier 40 is made of stress absorbing material, when the middle frame 31 is subjected to external force, the barrier 40 can absorb most of the force transmitted from the middle frame glue 60, and only a very small force will be transmitted to the colloid 24, making it difficult for the inside of the colloid 24 to be subjected to sufficient force to generate bubbles.

[0053] When the barrier 40 is made of other materials or methods, or the spacing between the first overlapping portion 21a and the second overlapping portion 21b is large, there is a certain gap between the barrier 40 and the colloid 24. In this way, even if the external force is transmitted to the barrier 40 along the middle frame 31 and the middle frame glue 60, it will no longer be transmitted to the colloid 24, thereby completely avoiding the impact force and force transmitted by the middle frame glue 60, so that no bubbles will be generated in the colloid 24.

[0054] As a further embodiment, Figure 4 As shown, a groove 41 is provided on the barrier 40, the opening of the groove 41 faces the middle frame glue 60, and the groove 41 is arranged on the side of the barrier 40 close to the second optical device 21, so that the groove 41 is communicated with the gap between the second optical device 21 and the middle frame 31. When the display module 20 is pressed on the middle frame 31, the middle frame glue 60 will flow into the groove 41, so that the contact area between the middle frame glue 60 and the second optical device 21 becomes larger, thereby increasing the connection area between the second optical device 21 and the middle frame 31 and improving the connection strength.

[0055] It can be understood that “the groove 41 is disposed on a side of the barrier 40 close to the second optical device 21” means that the opening of the groove 41 is also facing the second optical device 21, and the second optical device 21 is equivalent to a side wall of the groove 41. Therefore, when the middle frame glue 60 enters the groove 41, the middle frame glue 60 contacts the second optical device 21.

[0056] Further, such as Figure 5 As shown, relative to Figure 4 The plan, Figure 5The solution further increases the height of the groove 41, so that the groove 41 extends to the bottom of the support surface 311. At this time, the height of the groove 41 is greater than the distance between the second optical device 21 and the support surface 311, and the opening of the groove 41 is also toward the inner side of the middle frame 31. Through the above design, not only the contact area between the middle frame glue 60 and the second optical device 21 is increased, but also the contact area between the middle frame glue 60 and the middle frame 31 is increased, further increasing the connection area between the second optical device 21 and the middle frame 31, and improving the connection effect between the second optical device 21 and the middle frame 31; moreover, when the coating amount of the middle frame glue 60 is large, the groove 41 can also accommodate excess middle frame glue 60, so as to avoid the accumulation of the middle frame glue 60 on the support surface, resulting in the middle frame glue 60 being too thick, which affects the thickness of the display device 10.

[0057] It should be noted that the height of the groove 41 refers to the size of the groove 41 in the distance direction between the second optical device 21 and the back plate 32 .

[0058] As another further implementation, Figure 6 As shown, the second overlapping portion 21b is provided with an extension groove 211, and the opening of the extension groove 211 faces the support surface 311. Through the above design, it can be further ensured that there is enough glue to overflow into the extension groove 211, and the glue amount of the middle frame glue 60 in some areas is prevented from being too much, thereby avoiding the problem of uneven glue amount in the bonding area of ​​the second optical device 21 and the middle frame 31, which is conducive to enhancing the bonding strength between the second optical device 21 and the middle frame 31.

[0059] like Figure 7 As shown, optionally, the extension groove 211 is annular and arranged around the first optical device 22. Such a design can ensure a uniform glue amount effect in the bonding area around the second optical device 21 and the middle frame 31. Further, multiple circles of extension grooves 211 can be arranged on the second optical device 21, and the multiple circles of extension grooves 211 are arranged in sequence, and the openings of all the extension grooves 211 face the support surface 311, so as to further improve the uniform glue amount effect and improve the bonding strength between the second optical device 21 and the middle frame 31.

[0060] like Figure 8As shown, optionally, the extension groove 211 is in the shape of an elongated strip, one end of the extension groove 211 extends to the edge of the second optical device 21, flush with the edge of the second optical device 21, and the other end of the extension groove 211 extends toward the direction of the barrier 40, extending to between the edge of the second optical device 21 and the barrier 40. Through this design, in the process of pressing the second optical device 21 on the middle frame 31, when the outer side of the second overlapping portion 21b of the second optical device 21 first contacts the middle frame glue 60, as the second optical device 21 is pressed, the air is squeezed toward the inner side of the second overlapping portion 21b. Since the end of the extension groove 211 extends to the edge of the second optical device 21, the extension groove 211 can play the role of an air pipe, and guide the air located inside the second overlapping portion 21b to the outside of the second optical device 21, so as to avoid air accumulation in the middle frame glue 60, which affects the connection effect between the middle frame glue 60 and the middle frame 31 and the second optical device 21.

[0061] The bottom of the second overlapping portion 21 b has a plurality of extension grooves 211 , and each side of the second overlapping portion 21 b has a plurality of extension grooves 211 arranged in parallel, which is conducive to removing the air in each middle frame glue 60 .

[0062] like Fig. 9 As shown, optionally, the width of the extension groove 211 on the side close to the support surface 311 is smaller than the width of the extension groove 211 on the side away from the support surface 311, that is, the cross-section of the extension groove 211 presents a shape with a wide top and a narrow bottom, for example, the cross-section of the extension groove 211 is an inverted trapezoid. With this design, even if the outer side of the second overlapping portion 21b contacts the middle frame glue 60 first, and the middle frame glue 60 enters the extension groove 211, due to the small bottom size and large internal size of the extension groove 211, the amount of the middle frame glue 60 entering the extension groove 211 is small, and the extension groove 211 will not be filled or blocked, thereby ensuring the circulation of air in the extension groove 211 in the initial stage. Moreover, after the middle frame glue 60 solidifies, the middle frame glue 60 and the extension groove 211 form a mutually interlocking structure, which further improves the connection strength between the middle frame glue 60 and the second optical device 21.

[0063] As another further implementation, Fig.10 As shown, the display device 10 further includes a retaining wall 50, which is disposed on a side of the support surface 311 facing the second overlapping portion 21b and located at an end of the support surface 311 close to the blocking member 40. It can be understood that the retaining wall 50 is located on the support surface 311, the retaining wall 50 can be an integral structure with the middle frame 31, and the retaining wall 50 is located on the inner side of the support surface 311.

[0064] In this embodiment, the retaining wall 50 is annular and is disposed around the blocking member 40 , and a gap is provided between the retaining wall 50 and the blocking member 40 .

[0065] In this embodiment, a retaining wall 50 is added between the second overlapping portion 21b and the supporting surface 311, and the retaining wall 50 is located close to the blocking member 40, so that the retaining wall 50 can prevent the overflow of the middle frame glue 60 while not affecting the connection effect of the middle frame glue 60 on the second optical device 21 and the middle frame 31.

[0066] When the embodiment of the present application adopts the design of the retaining wall 50 combined with the barrier 40, in the process of pressing the second optical device 21 onto the middle frame 31, the retaining wall 50 will first block the middle frame glue 60 to prevent the middle frame glue 60 from continuing to overflow and contact the barrier 40. Even if part of the middle frame glue 60 exceeds the retaining wall 50, only a small part of the middle frame glue 60 is in contact with the barrier 40. At this time, when the middle frame 31 is subjected to external force, the middle frame glue 60 can only transfer a small part of the impact force to the barrier 40, which is conducive to further preventing the colloid 24 from being impacted.

[0067] It should be noted that in the above-mentioned multiple embodiments, the schemes between different embodiments can be combined with each other, for example, the groove 41 can be provided on the blocking member 40, and the extension groove 211 can be provided on the second overlapping portion 21b; or, the groove 41 can be provided on the blocking member 40, and the retaining wall 50 can be provided on the supporting surface 311; or, the extension groove 211 can be provided on the second overlapping portion 21b, and the retaining wall 50 can be provided on the supporting surface 311; or, the groove 41 can be provided on the blocking member 40, the extension groove 211 can be provided on the second overlapping portion 21b, and the retaining wall 50 can be provided on the supporting surface 311. The specific combination scheme can be selected according to the actual situation, and is not limited here.
