Embodiments of the present application provide a display assembly, which will be described in detail below.
Referring to fig. 1 and fig. 2, a display assembly 100 according to an embodiment of the present disclosure may include a first substrate 10, a second substrate 20, a main frame sealing adhesive 30, and a first retaining wall 40.
Wherein the first substrate 10 may have a first surface 11. It should be noted that the first substrate 10 may be an array substrate or a color filter substrate.
Wherein the second substrate 20 may have a second surface 21. The second surface 21 is disposed opposite to the first surface 11 of the first substrate 10. It should be noted that the second substrate 20 may be an array substrate or a color filter substrate. It can be understood that, when the first substrate 10 is an array substrate, the second substrate 20 is a color filter substrate; when the first substrate 10 is a color filter substrate, the second substrate 20 is an array substrate.
The main frame sealing adhesive 30 may be disposed between the first surface 11 and the second surface 21. The frame sealing adhesive 30, the first surface 11 and the second surface 21 can be enclosed into a plurality of display panels 50. It is understood that the periphery of each display panel 50 has the sealant 30 disposed around it. The display panel 50 includes liquid crystal 60 therein.
Wherein, the first retaining wall 40 may be disposed around the display panel 50. It can be understood that the first retaining wall 40 can support the first substrate 10 and the second substrate 20 to prevent the first substrate 10 and the second substrate 20 from being damaged by the main frame sealing adhesive 30 due to the first substrate 10 and the second substrate 20 being bent by a force during the cutting process. It should be noted that the first sub-retaining wall 40 may be made of a metal material, an insulating material, a photoresist material, or the like.
Wherein, the first retaining wall 40 is provided with a plurality of air flow channels 41. It can be understood that the air flow channel 41 can introduce external air into the motherboard 100 when the atmosphere is open (vacuum is broken), so that the periphery of the display panel 50 can be filled with air, and the internal and external pressures of the display panel 50 are balanced.
It should be noted that the terms "first", "second" and "third" in the description of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", "third" may explicitly or implicitly include one or more of the described features.
In some embodiments, the first retaining wall 40 may include a first sub-retaining wall 42 and a second sub-retaining wall 43. The first sub-retaining wall 42 may be disposed on the first surface 11, and the second sub-retaining wall 43 may be disposed on the second surface 21. The first sub-retaining wall 42 and the second sub-retaining wall 43 cooperate to form a plurality of air flow channels 41. In some embodiments, the first sub-retaining wall 42 may be integrally formed with the first substrate 10, and the second sub-retaining wall 43 may be integrally formed with the second substrate 20.
Specifically, referring to fig. 2, (1) in fig. 2 is a schematic structural diagram of a portion of the display module 100. (2) A schematic diagram of the structure of the film layer in the direction a in the display module 100 is shown. (3) A schematic diagram of the structure of the film layer of the display module 100 in the direction B is shown. (4) A schematic diagram of the structure of the film layer of the display module 100 in the C direction is shown.
The first sub-retaining wall 42 may include a plurality of first portions 421 and a plurality of second portions 422. The first portion 421 and the second portion 422 are adjacent to each other. A groove 4211 is formed on the first portion 421, and a first through hole 4221 exposing the first surface 11 is formed on the second portion 422. The second sub-wall 43 may include a plurality of third portions 431 and a plurality of fourth portions 432. The third portion 431 is disposed opposite to the groove 4211 and contacts with an inner surface of the groove 4211. The fourth portion 432 is disposed opposite to the first through hole 4221 and has a first gap 411 with the first surface 11.
It can be understood that the first slot 411 formed by the cooperation of the second portion 4221 of the first sub-retaining wall 42 and the fourth portion 432 of the second sub-retaining wall 43 is the air flow channel 41. At this time, the first sub-retaining wall 42 and the second sub-retaining wall 43 can cooperate to form a plurality of airflow channels 41 arranged at intervals, as shown in fig. 2 (4). Also, since the third portion 431 is disposed opposite to the groove 4211 and contacts with the inner surface of the groove 4211, it is possible to provide a good supporting function for the first substrate 10 and the second substrate 20 when performing cutting.
In some embodiments, to slow the airflow intensity when air enters the display assembly 100 when the atmosphere is open (breaking a vacuum). The first sub-retaining wall 42 and the second sub-retaining wall 43 can cooperate to form an embedded structure. That is, the second sub-retaining wall 43 is embedded in the first sub-retaining wall 42. So that the air flows around the display panel 100 to reduce the air flow strength and prevent the main sealant 30 from puncturing or deforming due to the air flow impact.
In order to further reduce the strength of the airflow, in some embodiments, the shortest distance between the fourth portion 432 of the second sub-wall 43 and the first side 4222 of the first through hole 4221 may be set to be greater than the shortest distance between the fourth portion 432 of the second sub-wall 43 and the first surface 11, and the shortest distance between the fourth portion 432 of the second sub-wall 43 and the first surface 11 may be set to be greater than the shortest distance between the fourth portion 432 of the second sub-wall 43 and the second side 4223 of the first through hole 4221. It should be noted that the first side edge 4222 of the first through hole 4212 is close to the main frame sealing adhesive 30, and the second side edge 4223 of the first through hole 4221 is far from the main frame sealing adhesive 30. It can be understood that, when the atmosphere is open, the sectional area of the airflow channel 41 through which the airflow flows when entering the display assembly 100 is gradually increased, so as to reduce the impact of the airflow on the main frame sealing adhesive 30 and prevent the main frame sealing adhesive 30 from puncturing or deforming due to the airflow impact.
It should be noted that in the description of the embodiments of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.
In some embodiments, referring to fig. 3, (1) in fig. 3 is a schematic structural view of a portion of the display assembly 100. (2) A schematic diagram of the structure of the film layer in the direction a in the display module 100 is shown. (3) A schematic diagram of the structure of the film layer of the display module 100 in the direction B is shown. (4) A schematic diagram of the structure of the film layer of the display module 100 in the C direction is shown.
The first sub-retaining wall 42 may include a plurality of second through holes 4212 exposing the first surface 11. The second sub-retaining wall 43 may include a plurality of fifth portions 433 and a plurality of sixth portions 434. The fifth portion 433 and the sixth portion 434 may be respectively disposed opposite to two adjacent second through holes 4212. The fifth portion 433 is in contact with the first surface 11, and a second gap 412 is formed between the sixth portion 434 and the first surface 11.
It can be understood that the second slit 412 formed by the first sub-wall 42 and the sixth portion 434 of the second sub-wall 43 is the air flow channel 41. At this time, the first sub-retaining wall 42 and the second sub-retaining wall 43 may cooperate to form a plurality of airflow channels 41 arranged at intervals, as shown in fig. 3 (4). Also, since the sixth portion 434 is in contact with the first surface 11, it is possible to provide a good support for the first substrate 10 and the second substrate 20 when performing dicing.
In order to further reduce the strength of the airflow, in some embodiments, the shortest distance between the sixth portion 434 of the second sub-wall 43 and the first side 4224 of the second through hole 4212 may be set to be greater than the shortest distance between the sixth portion 434 of the second sub-wall 43 and the first surface 11, and the shortest distance between the sixth portion 434 of the second sub-wall 43 and the first surface 11 may be set to be greater than the shortest distance between the sixth portion 432 of the second sub-wall 43 and the second side 4225 of the second through hole 4212. It should be noted that the first side edge 4224 of the second through hole 4212 is close to the main frame sealing adhesive 30, and the second side edge 4225 of the second through hole 4212 is far from the main frame sealing adhesive 30. It can be understood that, when the atmosphere is open, the sectional area of the airflow channel 41 through which the airflow flows when entering the display assembly 100 is gradually increased, so as to reduce the impact of the airflow on the main frame sealing adhesive 30 and prevent the main frame sealing adhesive 30 from puncturing or deforming due to the airflow impact.
In some embodiments, referring to fig. 4, (1) in fig. 4 is a schematic structural view of a portion of the display assembly 100. (2) A schematic diagram of the structure of the film layer in the direction a in the display module 100 is shown. (3) A schematic diagram of the structure of the film layer of the display module 100 in the direction B is shown. (4) A schematic diagram of the structure of the film layer of the display module 100 in the C direction is shown.
The first sub-retaining wall 42 may include a plurality of second through holes 4212 exposing the first surface 11. The second sub-retaining wall 43 may include a plurality of seventh portions 435 and a plurality of eighth portions 436. The seventh portion 435 and the eighth portion 436 may be respectively disposed opposite to the adjacent two second passages 4212, and each have a third gap 413 with the first surface 11.
It can be understood that the third gap 413 formed by the first sub-wall 42 and the seventh and eighth portions 435 and 436 of the second sub-wall 43 is the air flow channel 41. At this time, the first sub-retaining wall 42 and the second sub-retaining wall 43 can cooperate to form a communicating air flow channel 41, as shown in fig. 4 (4).
In order to further reduce the airflow intensity, in some embodiments, the shortest distance between the seventh portion 435 of the second sub-retaining wall 43 and the first side 4224 of the second through hole 4212 may be set to be greater than the shortest distance between the seventh portion 435 of the second sub-retaining wall 43 and the first surface 11, and the shortest distance between the seventh portion 435 of the second sub-retaining wall 43 and the first surface 11 may be set to be greater than the shortest distance between the seventh portion 435 of the second sub-retaining wall 43 and the second side 4225 of the second through hole 4212. It should be noted that the first side edge 4224 of the second through hole 4212 is close to the main frame sealing adhesive 30, and the second side edge 4225 of the second through hole 4212 is far from the main frame sealing adhesive 30. It can be understood that, when the atmosphere is open, the sectional area of the airflow channel 41 through which the airflow flows when entering the display assembly 100 is gradually increased, so as to reduce the impact of the airflow on the main frame sealing adhesive 30 and prevent the main frame sealing adhesive 30 from puncturing or deforming due to the airflow impact.
It is understood that the eighth portion 436 of the second sub-retaining wall 43 and the second through hole 4212 can be disposed in the same manner as the seventh portion 435 of the second sub-retaining wall 43 and the second through hole 4212.
In some embodiments, referring to fig. 5 and fig. 6, fig. 6 is a schematic view of a film structure of fig. 5 in the direction a. To further slow down the strength of the airflow, a plurality of second retaining walls 70 may be disposed around the first retaining wall 40. In some embodiments, the second retaining wall 70 may include a third sub-retaining wall 71 and a fourth sub-retaining wall 72. The third sub-retaining wall 71 is disposed on the first surface 11, and the fourth sub-retaining wall 72 is disposed on the second surface 21. The third sub-retaining wall 71 and the fourth sub-retaining wall 72 can cooperate to form a plurality of second air flow channels 73.
It should be noted that the distance between the second retaining wall 70 and the first retaining wall 40 can be between 500 micrometers (um) and 1000 micrometers (um). The width of the first retaining wall 40 and the second retaining wall 70 may be between 50 micrometers (um) to 100 micrometers (um).
It can be understood that the more the second retaining walls 70 having the second air flow passages 73 are provided at the periphery of the first retaining wall 40, the better the air flow strength reducing effect.
It is understood that when the first retaining wall 40 and/or the second retaining wall 70 are disposed as shown in fig. 2 or 3, the first sub-retaining wall 42 and the second sub-retaining wall can cooperate to form a plurality of first air flow passages disposed at intervals; and/or the third sub-retaining wall 71 and the fourth sub-retaining wall 72 may cooperate to form a plurality of second air flow channels 73 arranged at intervals. That is, the first sub-retaining wall 42 and the second sub-retaining wall 43 can support the first substrate 10 and the second substrate 20 well; and/or the third sub-retaining wall 71 and the fourth sub-retaining wall 72 can support the first substrate 10 and the second substrate 20 well.
In some embodiments, when the first retaining wall 40 and the second retaining wall 70 are disposed in the same manner as in fig. 4, the first sub-retaining wall 42 and the second sub-retaining wall 43 do not contact each other under the condition of no force, and the display panel 50 slightly bends the first sub-retaining wall 42 and the second sub-retaining wall 43 to contact each other to balance the external force when the external force reaches a certain degree. The third sub-retaining wall 71 and the fourth sub-retaining wall 72 are not in contact, and when the external force reaches a certain degree, the display panel 50 slightly bends the third sub-retaining wall 71 and the fourth sub-retaining wall 72 to contact each other to balance the external force.
However, since the supporting force of the first retaining wall 40 and the second retaining wall 70 is weaker, there is still a possibility that the first substrate 10, the second substrate 20 and the frame sealant 30 are damaged during the cutting process.
In contrast, as shown in fig. 7, an auxiliary sealant 80 may be disposed on the periphery of the second barrier wall 70. The auxiliary sealant 80 may be disposed around the second retaining wall 70 and supported between the first substrate 10 and the second substrate 20. It is understood that the auxiliary sealant 80 has an opening thereon, so that air flows into the display device 100 when the atmosphere is open.
It should be noted that the first sub-retaining wall 42 and the third sub-retaining wall 71 disposed on the first substrate 10, and the second sub-retaining wall 43 and the fourth sub-retaining wall 72 disposed on the second substrate 20 may be composed of one layer of film, or may be composed of multiple layers of films.
In some embodiments, referring to fig. 8, when the first sub-retaining wall 42 disposed on the first substrate 10 is a multi-layer film structure, a width of a first film structure 423 of the first sub-retaining wall 42 close to the first substrate 10 is smaller than a width of a second film structure 424 of the first sub-retaining wall 42 far from the first substrate 10. It can be understood that, at this time, the volume of the first air flow channel 41 is increased, and the time taken for the air flow to flow through the first air flow channel 41 is longer, so that the impact force of the air flow can be further reduced, and the main frame sealing adhesive 30 is prevented from puncturing or deforming due to the impact of the air flow.
It can be understood that, when the third sub-retaining wall 71 disposed on the first substrate 10 is a multilayer film structure, the third sub-retaining wall 71 may also be disposed in the same manner as the first sub-retaining wall 71.
The display assembly 100 provided in the embodiment of the present application includes a first substrate 10, a second substrate 20, a main frame glue 30, and a first retaining wall 40.
