Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a support member, a liquid crystal panel and a display module. Background Art

[0002] Liquid crystal display panels are one of the most important display panels on the market today, with the characteristics of low cost, high resolution, high contrast and fast response speed. In the production process of liquid crystal display panels, in order to improve the yield of display panels, quality tests of different items are generally carried out during the production process.

[0003] Among them, the quality test includes a compressive mechanical test on the liquid crystal panel. Specifically, pressure is applied to the liquid crystal panel through an external testing device to test the compressive performance of the liquid crystal panel. During the compressive mechanical test, the support members in the liquid crystal panel play a major supporting role. The liquid crystal panel in the related art generally includes a main support member and a secondary support member. The main support member is directly used to support two relatively arranged substrates. When the pressure is large, the main support member will be compressed, and the secondary support member plays the role of auxiliary support. Due to the large height difference between the main support member and the secondary support member, when the main support member is subjected to a large pressure, it needs to be compressed before the secondary support member can play the role of auxiliary support. During the compression process, because the pressure has a lateral component, the main support member slips, scratches the alignment film provided on the substrate, and generates alignment film debris. When the display panel is displayed, there will be a problem of broken bright spots. Utility Model Content

It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in this application.

[0041] Please attend Figure 1 , an embodiment of the present application provides a display module, the display module comprising:

[0042] Backlight source 1, used to provide light source required for displaying pictures;

[0043] The liquid crystal panel 2 is arranged on the light-emitting side of the backlight source 1 and is used for displaying images;

[0044] The driving circuit board 3 is disposed between the backlight source 1 and the liquid crystal panel 2 and is used to control and drive the liquid crystal panel 2 to display a target image.

[0045] Among them, the backlight source 1 and the driving circuit board 3 are both made by conventional technical means, and their structures are also conventional structures, which will not be introduced in detail here.

[0046] For LCD panel 2, see Figure 2 , the liquid crystal panel 2 comprises:

[0047] An array substrate 21 and a pairing substrate 22, wherein the array substrate 21 and the pairing substrate 22 are arranged opposite to each other;

[0048] A first alignment film 23 and a second alignment film 24, wherein the first alignment film 23 is disposed on a side of the array substrate 21 facing the cell substrate 22, and the second alignment film 24 is disposed on a side of the cell substrate 22 facing the array substrate 21, and a plurality of liquid crystals are disposed between the first alignment film 23 and the second alignment film 24;

[0049] A support member 28 is disposed between the first alignment film 23 and the second alignment film 24 , and the support member 28 is in contact with the first alignment film 23 and / or the second alignment film 24 .

[0050] The technical means provided in this embodiment mainly realizes the relative arrangement of the array substrate 21 and the pairing substrate 22 by using the support member 28, plays a supporting role for the array substrate 21 and the pairing substrate 22, and improves the pressure resistance of the liquid crystal panel 2. When the liquid crystal panel 2 is subjected to a pressure mechanical test, the support member 28 can play a compressive role, and the support member 28 contacts the first alignment film 23 and the second alignment film 24 through its own structure. When subjected to pressure, it can effectively reduce the probability of the support member 28 slipping due to the pressure, thereby avoiding the support member 28 from scratching the alignment film, causing the liquid crystal panel 2 to have broken bright spots when displaying. It should be noted that the number of the support members 28 is multiple, and the selection is made according to the size of the liquid crystal panel 2. The multiple support members 28 are arranged at intervals to provide support strength for different positions.

[0051] It should also be noted that, in addition to the above structure, the liquid crystal panel 2 also includes a black matrix 25, a first polarizer 26, and a second polarizer 27. The black matrix 25 is disposed between the first alignment film 23 and the array substrate 21 and / or between the second alignment film 24 and the cell substrate 22 to shield light. The first polarizer 26 is disposed on the side of the array substrate 21 away from the cell substrate 22, and the second polarizer 27 is disposed on the side of the cell substrate 22 away from the array substrate 21.

[0052] Based on the above-mentioned support member 28 with a special structure, the pressure resistance of the liquid crystal panel 2 can be improved, and the probability of scratching the alignment film due to the slippage of the support member 28 can be reduced. In this regard, the support member 28 will be introduced in detail in the following embodiments:

[0053] See also Figures 3 to 6 A support member 28 is used to maintain the gap between the liquid crystal panel 2 and the cell, the support member has a height direction and a circumferential direction, and includes:

[0054] A support body 281, the projection along the height direction is in a ring shape, and the side of the support body 281 facing the center of the ring shape is the circumferential inner side, and the support body 281 includes a top, and the projection of the top in the height direction is also in a ring shape;

[0055] A first supporting auxiliary body 282, disposed on the inner side of the supporting main body 281 in the circumferential direction and extending along the circumferential direction;

[0056] The first supporting sub-body 282 includes a first supporting surface 2821 , the first supporting surface 2821 is connected to the top of the supporting main body 281 , and along the height direction, the first supporting surface 2821 extends toward the center direction of the ring shape.

[0057] The technical solution provided by the present application is mainly to connect the top of the support body 281 with the first support surface 2821, and the first support surface 2821 extends in the height direction and in the radial direction, so that the first support surface 2821 is inclined, and the first support surface 2821 and the top of the support body 281 present a gradual transition effect in the height direction, so as to avoid the first support surface 2821 and the top step difference being too large. The support body 281 plays a main supporting role, and the first support sub-body 282 can gradually play an auxiliary supporting role as the pressure increases. In detail, when the test pressure is applied to the liquid crystal panel 2, the support body 281 first plays a main supporting role. As the test pressure increases, the support body 281 is compressed. During the compression process, the first support surface 2821 will point from the outside to the inside, and gradually become flush with the top of the support body 281, thereby playing an auxiliary supporting role. Since there is no excessive step difference between the support body 281 and the first support sub-body 282, the support body 281 can always play a supporting role, and the first support sub-body 282 can also play an auxiliary supporting role when the support body 281 is compressed due to excessive force, thereby effectively avoiding the problem of slippage of the main support member 28 during compression due to the large step difference between the main support member 28 and the sub-support member 28 in the related technology, and then effectively preventing the alignment film from being damaged due to the slippage of the support member 28, resulting in the problem of broken bright spots.

[0058] In some embodiments, the first supporting sub-body 282 also includes a second supporting surface 2822, and the supporting body 281 also includes a bottom. Along the height direction, the bottom is arranged opposite to the top, and the two sides of the second supporting surface 2822 are respectively connected to the bottom of the supporting body 281 and the side of the first supporting surface 2821 away from the top of the supporting body 281; along the height direction, with the connection between the second supporting surface 2822 and the bottom of the supporting body 281 as the starting point, the second supporting surface 2822 extends toward the center direction of the ring shape. The second supporting surface 2822 is mainly provided to adapt to the pressure on the side opposite to the first supporting surface 2821. For example: assuming that the supporting member 28 is provided on the first alignment film 23, the first supporting surface 2821 is toward the side of the matching box substrate 22, and is used to withstand the pressure from the side of the matching box substrate 22; the second supporting surface 2822 is toward the side of the array substrate 21, and is used to withstand the pressure from the side of the array substrate 21. This can effectively prevent the supporting member 28 from sliding on the side of the first alignment film 23 and sliding on the side of the second alignment film 24.

[0059] It should be noted that the first support surface 2821 and the second support surface 2822 may be symmetrical or not, preferably symmetrical. However, the second support surface 2822 needs to have an inclined surface or an arc surface for transition, and the transition surface is the connection between the second support surface 2822 and the bottom of the support body 281 as the starting point, and the second support surface 2822 extends in the radial direction. When the array substrate 21 applies pressure to the second support surface 2822, the support member 28 is compressed, and the contact area of ​​the second support surface 2822 with the array substrate 21 increases with the increase of pressure, thereby playing an auxiliary support role to prevent the support member 28 from slipping on the first alignment film 23.

[0060] Furthermore, the connections between the first support surface 2821, the second support surface 2822 and the support body 281 are all arc-shaped connections. By setting the connection between the first support surface 2821 and the second support surface 2822, the connection between the first support surface 2821 and the support body 281, and the connection between the second support surface 2822 and the support body 281 as arc-shaped connections, it can be further ensured that the support member 28 will not scratch the alignment film. In other words, through the arc-shaped setting, even if the support member 28 slips due to unbalanced force, such as excessive lateral pressure component, the probability of the alignment film being scratched by the slip of the support member 28 can be effectively reduced because the connection points are all arc-shaped connections.

[0061] Furthermore, the first support surface 2821 and the second support surface 2822 are both curved surfaces, and the first support surface 2821 is smoothly connected to the second support surface 2822. By limiting the first support surface 2821 and the second support surface 2822 to curved surfaces, it is helpful to improve the support main body 281 during the compression process, so that the support auxiliary body can better transition to contact with the alignment film and play the role of auxiliary support. Compared with the related art, there is a certain step difference between the main support member 28 and the auxiliary support member 28, resulting in that the auxiliary support member 28 cannot play the role of auxiliary support in time during the compression process of the main support member 28, resulting in the possibility of slippage of the main support member 28. In the present embodiment, there is basically no step difference problem in the supporting function between the support main body 281 and the support sub-body. Under a specific pressure, the support main body 281 and the support sub-body respectively bear the pressure-bearing function. When the pressure is too large and the support main body 281 is compressed, the support sub-body can seamlessly transition to contact with the alignment film to share the pressure, thereby effectively preventing the support main body 281 from slipping due to excessive pressure.

[0062] In some embodiments, the support member 28 further includes a second support sub-body 283, the side of the support body 281 away from the center of the ring shape is the circumferential outer side, the second support sub-body 283 is arranged on the circumferential outer side of the support body 281 and extends along the circumferential direction, and the second support sub-body 283 includes a third support surface 2831, the third support surface 2831 is connected to the top of the support body 281 and extends in the height direction in a direction away from the first support sub-body 282. The second support sub-body 283 and the first support sub-body 282 can be symmetrically arranged or asymmetrically arranged. In this embodiment, a symmetrical arrangement is preferred to facilitate the molding of the support member 28 and to make the force more uniform.

[0063] This embodiment mainly utilizes the top of the support body 281 to connect with the third support surface 2831, and the third support surface 2831 extends in the height direction and in the radial direction, so that the third support surface 2831 is inclined, and the third support surface 2831 and the top of the support body 281 present a gradual transition effect in the height direction, so as to avoid the third support surface 2831 and the top The step difference is too large. The support body 281 plays a main supporting role, and the second support sub-body 283 can gradually play an auxiliary supporting role as the pressure increases. In detail, when the test pressure is applied to the liquid crystal panel 2, the support body 281 first plays a main supporting role. As the test pressure increases, the support body 281 is compressed. During the compression process, the first support surface 2821 and the third support surface 2831 will point from the outside to the inside, and gradually become flush with the top of the support body 281, thereby playing an auxiliary supporting role. Since there is no excessive step difference between the support body 281 and the second support sub-body 283 and the first support sub-body 282, the support body 281 can always play a supporting role, and the first support sub-body 282 and the second support sub-body 283 can also play an auxiliary supporting role when the support body 281 is compressed due to excessive force, thereby effectively avoiding the problem of the main support 28 slipping during the compression process due to the large step difference between the main support member 28 and the sub-support member 28 in the related art, and then effectively preventing the alignment film from being damaged by the slip of the support member 28 and the problem of broken bright spots. In addition, because two relative support sub-bodies, namely the first support sub-body 282 and the second support sub-body 283, are provided, the force on the support member 28 is more balanced.

[0064] Furthermore, the second supporting sub-body 283 further includes a fourth supporting surface 2832, and the supporting main body 281 further includes a bottom, and along the height direction, the bottom is arranged opposite to the top. The two sides of the fourth supporting surface 2832 are respectively connected to the bottom of the supporting main body 281 and the side of the third supporting surface 2831 away from the top; along the height direction, with the connection between the fourth supporting surface 2832 and the bottom of the supporting main body 281 as a starting point, the fourth supporting surface 2832 extends in a direction away from the first supporting sub-body 282. The fourth supporting surface 2832 has a similar function to the second supporting surface 2822, mainly to play a supporting role on the side opposite to that supported by the third supporting surface 2831. In detail, the fourth supporting surface 2832 is provided mainly to adapt to the pressure on the side opposite to the third supporting surface 2831. For example: assuming that the supporting member 28 is provided on the first alignment film 23, the third supporting surface 2831 is toward the side of the matching box substrate 22, and is used to withstand the pressure from the side of the matching box substrate 22. The fourth supporting surface 2832 is toward the side of the array substrate 21, and is used to withstand the pressure from the side of the array substrate 21. This can effectively prevent the supporting member 28 from sliding on the side of the first alignment film 23 and sliding on the side of the second alignment film 24.

[0065] Furthermore, the connections between the third support surface 2831, the fourth support surface 2832 and the support body 281 are all arc-shaped. By setting the connection between the third support surface 2831 and the fourth support surface 2832, the connection between the third support surface 2831 and the support body 281, and the connection between the fourth support surface 2832 and the support body 281 as arc-shaped connections, it can be further ensured that the support member 28 will not scratch the alignment film. In other words, through the arc-shaped setting, even if the support member 28 slips due to unbalanced force, such as excessive lateral pressure component, the probability of the alignment film being scratched by the slip of the support member 28 can be effectively reduced because the connection points are all arc-shaped connections.

[0066] Furthermore, the third support surface 2831 and the fourth support surface 2832 are both curved surfaces and the third support surface 2831 is smoothly connected to the fourth support surface 2832. By limiting the third support surface 2831 and the fourth support surface 2832 to curved surfaces, it is beneficial to improve the support main body 281 during the compression process, so that the support sub-body can better transition to contact with the alignment film and play the role of auxiliary support. Compared with the related art, there is a certain step difference between the main support member 28 and the auxiliary support member 28, resulting in that the auxiliary support member 28 cannot play the role of auxiliary support in time during the compression process of the main support member 28, resulting in the possibility of slippage of the main support member 28. In the present embodiment, there is basically no step difference problem in the supporting function between the support main body 281 and the support sub-body. Under a specific pressure, the support main body 281 and the support sub-body respectively bear the pressure-bearing function. When the pressure is too large and the support main body 281 is compressed, the support sub-body can seamlessly transition to contact with the alignment film to share the pressure, thereby effectively preventing the support main body 281 from slipping due to excessive pressure.

[0067] See also Figure 5 In some embodiments, the support body 281 is annular, which is simpler in manufacturing process than other annular structures with edges, and can also avoid the problem of damage to the alignment film caused by the edges. It should also be noted that the support sub-bodies (the first support sub-body 282 and the second support sub-body 283) are all extended along the circumference of the support body 281, and the support surfaces of the support sub-bodies are all curved surfaces. In the manufacturing process, the currently more mature annular curved surface shape can be selected for manufacturing and molding. For example, in this embodiment, the support member 28 is preferably in the shape of a swimming ring.

[0068] In summary, through the improvement of the structure of the support member 28, firstly, the strength of the liquid crystal panel 2 can be effectively enhanced, so that the product can smoothly pass the mechanical test and shorten the product development cycle; secondly, the support member 28 provided in the present application can play the role of the main support member 28 in the related technology, and can also play the role of the auxiliary support member 28. It is formed in one step and does not need to be produced separately, which is conducive to cost reduction.
