随着显示技术的发展，大尺寸的显示装置得到了越来越广泛地应用。当大尺寸显示装置固定在壳体上时，为了使壳体能够更加稳固地支撑显示装置，显示装置与壳体之间通常采用多个连接点进行连接，以防止显示装置有较大区域悬空。然而，由于尺寸较大，显示装置与壳体之间的配合误差也会较大，当多个连接点均完成固定后，部分连接点容易产生较大的应力集中，显示装置在应力集中的作用下将会出现画面显示不均(Mura)的现象。With the development of display technology, large-size display devices have been more and more widely used. When a large-size display device is fixed on the housing, in order to enable the housing to support the display device more stably, multiple connection points are usually used for connection between the display device and the housing to prevent the display device from hanging in a large area. However, due to the large size, the fit error between the display device and the housing will also be large. When multiple connection points are fixed, some of the connection points are prone to large stress concentration. The display device plays a role in stress concentration. There will be a phenomenon of uneven display (Mura) on the screen.
图1A为一种汽车电子仪表盘的截面结构示意图。如图1A所示，该汽车电子仪表盘包括壳体100和位于壳体100内的显示装置200(图中虚线框内)。壳体100被配置为容纳并支撑显示装置200。显示装置200分别与壳体100在A面和B面连接，例如A面和B面可以设计为彼此基本平行。例如，显示装置200通过双面胶带301与壳体100在A面粘接，显示装置200通过连接部201与壳体100在B面连接，例如连接部201为螺柱，螺柱通过螺钉302与B面连接。然而，显示装置200通过双面胶带301与壳体100在A面完成粘接后，由于A面与B面之间的平行度误差或高度误差或B面自身的平面度误差，螺柱201相对于B面的高度与设计高度之间也会出现偏差。一般来讲，尺寸偏差与基本尺寸的大小成正比，由于显示装置200和壳体100的尺寸均较大，螺柱201与B面的高度偏差也会较大。并且常用的双面胶带可压缩性较小，通过调节双面胶带的厚度来调节连接部与第二连接面的高度误差不易实现。拧入螺钉302锁紧螺柱201后，将会在螺柱201处产生集中应力。Fig. 1A is a schematic diagram of a cross-sectional structure of an automobile electronic instrument panel. As shown in FIG. 1A, the automobile electronic instrument panel includes a housing 100 and a display device 200 (in a dashed frame in the figure) located in the housing 100. The housing 100 is configured to accommodate and support the display device 200. The display device 200 is connected to the housing 100 on the A side and the B side, for example, the A side and the B side may be designed to be substantially parallel to each other. For example, the display device 200 is adhered to the housing 100 on side A through a double-sided tape 301, and the display device 200 is connected to the housing 100 on side B through a connecting portion 201. For example, the connecting portion 201 is a stud, and the stud is connected to the housing 100 through a screw 302. B-side connection. However, after the display device 200 is bonded to the housing 100 on the A side through the double-sided tape 301, the stud 201 is opposite due to the parallelism error or height error between the A side and the B side or the flatness error of the B side itself. There will also be deviations between the height of the B surface and the design height. Generally speaking, the size deviation is proportional to the size of the basic size. Since the display device 200 and the housing 100 are both larger in size, the height deviation between the stud 201 and the B surface will also be larger. In addition, the commonly used double-sided tapes are less compressible, and it is not easy to adjust the height error between the connecting portion and the second connecting surface by adjusting the thickness of the double-sided tape. After the screw 302 is screwed in to lock the stud 201, concentrated stress will be generated at the stud 201.
图1B为图1A中螺柱与螺钉的放大结构示意图。例如，如图1B所示，壳体100的底板上开设有通孔101，螺柱201的一部分***通孔101中。如图1B所示，在完成螺钉302与螺柱201的紧固连接后，螺柱201的端面相 对于B面的高度为H，此时螺钉302没有对螺柱201产生拉压应力。若在螺柱201***通孔101中后且在拧入螺钉302之前，螺柱201***通孔101的长度小于设计长度，即螺柱201的端面相对于B面的高度小于H，在螺钉拧入螺柱的深度一定的情况下，螺钉302将会对螺柱201产生拉力，从而使显示装置在螺柱处产生拉应力。拉应力会使显示装置200产生画面显示不均(Mura)的现象。Fig. 1B is an enlarged schematic view of the stud and screw in Fig. 1A. For example, as shown in FIG. 1B, the bottom plate of the housing 100 is provided with a through hole 101, and a part of the stud 201 is inserted into the through hole 101. As shown in Fig. 1B, after the screw 302 and the stud 201 are fastened and connected, the height of the end surface of the stud 201 relative to the surface B is H. At this time, the screw 302 does not generate tension and compression stress on the stud 201. If after the stud 201 is inserted into the through hole 101 and before the screw 302 is screwed in, the length of the stud 201 inserted into the through hole 101 is less than the design length, that is, the height of the end surface of the stud 201 relative to the surface B is less than H, and the screw When the depth of the inserted stud is constant, the screw 302 will generate a tensile force on the stud 201, thereby causing the display device to generate tensile stress at the stud. The tensile stress may cause the display device 200 to produce a phenomenon of uneven display (Mura).
图1C为另一种汽车电子仪表盘的截面结构示意图。如图1C所示，该汽车电子仪表盘与图1A所示的电子仪表盘的不同在于，显示装置200的连接部201为凸台201，凸台201与壳体100在B面接触连接。然而，由于A面与B面之间的平行度误差或高度误差或B面自身的平面度误差，凸台201与B面的相对位置也存在偏差。例如，凸台201与B面之间的距离可能大于设计尺寸，凸台201与B面无法接触，此时B面无法起到支撑显示装置200的作用。例如，显示装置被固定后，凸台201与B面可能由于位置干涉而相互挤压，凸台201将会对显示装置200产生压应力。压应力会使显示装置200产生画面显示不均的现象。Fig. 1C is a schematic cross-sectional structure diagram of another automobile electronic instrument panel. As shown in FIG. 1C, the difference between the automobile electronic instrument panel and the electronic instrument panel shown in FIG. 1A is that the connecting portion 201 of the display device 200 is a boss 201, and the boss 201 is in contact with the housing 100 on the B surface. However, due to the parallelism error or height error between the A surface and the B surface or the flatness error of the B surface itself, the relative position of the boss 201 and the B surface also has a deviation. For example, the distance between the boss 201 and the surface B may be greater than the designed size, and the boss 201 cannot contact the surface B, and the surface B cannot support the display device 200 at this time. For example, after the display device is fixed, the boss 201 and the surface B may squeeze each other due to positional interference, and the boss 201 will generate compressive stress on the display device 200. Compressive stress may cause uneven display of the display device 200.
针对以上问题，本公开的实施例提供一种显示设备及交通工具。该显示设备包括壳体和至少部分位于壳体内的显示装置。显示装置与壳体分别在两处进行连接，并且两个连接处的至少之一采用固化胶连接。采用固化胶连接可以增大连接部件之间允许的误差范围，避免连接处产生应力集中。显示装置与壳体的两个连接处的至少之一采用固化胶连接，可以防止显示装置在连接处产生应力集中，从而避免出现画面显示不均的现象。In view of the above problems, the embodiments of the present disclosure provide a display device and a vehicle. The display device includes a housing and a display device at least partially located in the housing.

The cover 210 is connected to the first connection surface A, and the display assembly 220 is connected to the second connection surface B.

采用固化胶连接可以增大连接部件之间允许的误差范围，避免连接处产生应力集中。盖板与第一连接面之间的连接和显示组件第二连接面之间的连接的至少之一采用固化胶连接，可以防止显示装置在连接处产生应力集中，从而避免出现画面显示不均的现象。The use of curing glue to connect can increase the allowable error range between the connected parts and avoid stress concentration at the connection. At least one of the connection between the cover plate and the first connection surface and the connection between the second connection surface of the display assembly is connected by curing glue, which can prevent the display device from generating stress concentration at the connection, thereby avoiding uneven display of the picture Phenomenon.
例如，连接显示装置与壳体的步骤包括：在需要采用固化胶进行连接的连接处通过滴注等方式注入液态的固化胶；将显示装置放入壳体内，并确定显示装置和壳体的相对位置；将显示装置以及壳体置于固化所需要的环境中以完成固化胶的固化。For example, the step of connecting the display device and the housing includes: injecting liquid curing glue by dripping or other methods at the connection where the curing glue is needed; putting the display device into the housing, and determining the relative relationship between the display device and the housing. Position: Place the display device and the housing in the environment required for curing to complete the curing of the curing glue.
需要说明的是，固化胶是指能够在一定条件下从液态转化为具有一定机械强度的固态的胶。例如，固化胶可以为光学透明胶(Optical Clear Resin,OCR)。例如，OCR胶的固化过程包括在60℃的温度下进行2-3小时的预固化和在常温下进行24小时的最终固化。例如，固化胶还可以为液态光学胶(Liquid Optical Clear Adhesive,LOCA)或其他具有类似功能的胶。本公开的实施例不限定固化胶的具体类型。It should be noted that the cured glue refers to a glue that can be transformed from a liquid state to a solid state with a certain mechanical strength under certain conditions. For example, the curing glue may be Optical Clear Resin (OCR). For example, the curing process of OCR glue includes pre-curing at 60°C for 2-3 hours and final curing at room temperature for 24 hours. For example, the cured adhesive may also be Liquid Optical Clear Adhesive (LOCA) or other adhesives with similar functions. The embodiments of the present disclosure do not limit the specific type of curing glue.
例如，如图2所示，壳体100包括底板110、侧壁120、延伸部130以及外缘部140。例如，底板110、侧壁120、延伸部130以及外缘部140的厚度可以相同，但不限于此。例如，底板110大致为一平板形状。侧壁120为环形板，从底板110的边缘沿大致垂直于底板110的方向向底板110的同一侧延伸。例如，延伸部130为环形板，从侧壁120远离底板110的边缘向外侧延伸，其延伸方向大致平行于底板110的延伸方向。这里的向外侧延伸是指，向远离侧壁120围绕形成的内部空间的方向延伸。例如，外缘部140也为环 形板，从延伸部130的远离侧壁120的边缘沿大致垂直于延伸部130的方向向远离底板110的方向延伸。底板110和环形的侧壁120围成凹槽150。凹槽150被配置为容纳全部或部分显示装置200。延伸部130的远离底板110的表面为第一连接面A，底板110的靠近凹槽150的表面为第二连接面B。底板110的靠近凹槽150的表面也可以称为凹槽150的底面，也就是说，凹槽150的底面为上述的第二连接面B。例如，第一连接面A与第二连接面B大致平行。For example, as shown in FIG. 2, the housing 100 includes a bottom plate 110, a side wall 120, an extension part 130 and an outer edge part 140. For example, the thickness of the bottom plate 110, the side wall 120, the extension portion 130, and the outer edge portion 140 may be the same, but is not limited thereto. For example, the bottom plate 110 is substantially in the shape of a flat plate. The side wall 120 is an annular plate extending from the edge of the bottom plate 110 to the same side of the bottom plate 110 in a direction substantially perpendicular to the bottom plate 110. For example, the extension portion 130 is an annular plate extending from the edge of the side wall 120 away from the bottom plate 110 to the outside, and the extending direction thereof is substantially parallel to the extending direction of the bottom plate 110. Extending to the outside here refers to extending in a direction away from the internal space formed by the side wall 120. For example, the outer edge portion 140 is also a ring-shaped plate, and extends from an edge of the extension portion 130 away from the side wall 120 in a direction substantially perpendicular to the extension portion 130 to a direction away from the bottom plate 110. The bottom plate 110 and the annular side wall 120 enclose a groove 150. The groove 150 is configured to accommodate all or part of the display device 200. The surface of the extension 130 away from the bottom plate 110 is the first connection surface A, and the surface of the bottom plate 110 that is close to the groove 150 is the second connection surface B. The surface of the bottom plate 110 close to the groove 150 may also be referred to as the bottom surface of the groove 150, that is, the bottom surface of the groove 150 is the second connecting surface B described above. For example, the first connection surface A and the second connection surface B are substantially parallel.
需要说明的是，上述壳体100的结构仅为一种示例，壳体100也可以为其他结构。例如，底板110、侧壁120、延伸部130以及外缘部140的厚度可以不相同。例如，底板110也可以为曲面板。例如，侧壁120也可以不与底板110垂直。例如，延伸部130也可以为曲面板。例如，延伸部130与底板110也可以不平行。例如，外缘部140也可以不与延伸部130垂直。例如，壳体100可以不包括外缘部140。底板110、侧壁120和延伸部130可以实现壳体100与显示装置200的连接。上述底板110、侧壁120、延伸部130以及外缘部140可以一体形成也可以拼接形成。本公开不限定壳体的具体结构。It should be noted that the structure of the housing 100 described above is only an example, and the housing 100 may also have other structures. For example, the thickness of the bottom plate 110, the side wall 120, the extension portion 130, and the outer edge portion 140 may be different. For example, the bottom plate 110 may also be a curved plate. For example, the side wall 120 may not be perpendicular to the bottom plate 110. For example, the extension 130 may also be a curved panel. For example, the extension 130 and the bottom plate 110 may not be parallel. For example, the outer edge portion 140 may not be perpendicular to the extension portion 130. For example, the housing 100 may not include the outer edge portion 140. The bottom plate 110, the side wall 120 and the extension 130 may realize the connection between the housing 100 and the display device 200. The bottom plate 110, the side wall 120, the extension portion 130, and the outer edge portion 140 may be formed integrally or spliced together. The present disclosure does not limit the specific structure of the housing.
例如，壳体100用于支撑显示装置200，其材料可以为具有一定机械强度的金属材料、有机材料或复合材料。For example, the housing 100 is used to support the display device 200, and its material may be a metal material, an organic material, or a composite material with a certain mechanical strength.
例如，如图2所示，盖板210例如为平板，盖板210与第一连接面A大致平行，在平行于第一连接面或第二连接面的方向上，盖板伸出到显示组件的边缘的外侧，以与第一连接面连接。或者说，盖板的面积大于显示组件220在盖板210上的正投影的面积，且显示组件220在盖板210上的正投影全部落入盖板210的范围内，因此盖板210包括与显示组件交叠的部分和伸出到显示组件的边缘的外侧的环形部分。另外，盖板210也可以为曲面板，此时盖板仍然包括与显示组件交叠的部分和伸出到显示组件的边缘的外侧的环形部分。For example, as shown in FIG. 2, the cover plate 210 is, for example, a flat plate, and the cover plate 210 is approximately parallel to the first connection surface A. In a direction parallel to the first connection surface or the second connection surface, the cover plate extends to the display assembly. The outer side of the edge to connect with the first connecting surface. In other words, the area of the cover plate is larger than the area of the orthographic projection of the display assembly 220 on the cover plate 210, and the orthographic projection of the display assembly 220 on the cover plate 210 falls within the range of the cover plate 210. Therefore, the cover plate 210 includes The overlapping part of the display assembly and the annular part protruding to the outside of the edge of the display assembly. In addition, the cover 210 may also be a curved panel. At this time, the cover still includes a part that overlaps the display assembly and an annular part that protrudes outside the edge of the display assembly.
例如，如图2所示，显示装置200的至少一部分位于壳体100内。显示组件220的至少一部分位于凹槽110内。在平行于第一连接面A或第二连接面B的方向，盖板210位于外缘部140的内侧。盖板210的伸出到显示组件220的边缘的外侧的环形部分与第一连接面A至少部分交叠，且与第一连接面A在交叠处连接。例如，如图2所示，盖板210与第一连接面A在交叠处 通过双面胶带301粘接。For example, as shown in FIG. 2, at least a part of the display device 200 is located in the housing 100. At least a part of the display assembly 220 is located in the groove 110. In a direction parallel to the first connection surface A or the second connection surface B, the cover plate 210 is located inside the outer edge portion 140. The annular part of the cover plate 210 protruding to the outside of the edge of the display assembly 220 at least partially overlaps the first connection surface A, and is connected to the first connection surface A at the overlap point. For example, as shown in FIG. 2, the cover plate 210 and the first connecting surface A are adhered by a double-sided tape 301 at the overlap.
例如，如图2所示，显示组件220还包括连接部201，用于与壳体100连接，例如，与第二连接面B连接。连接部201位于显示组件220的面对第二连接面B的一侧，且朝向第二连接面B凸出。第二连接面B所在的壳体的底板110上开设有盲孔111，与连接部201一一对应，且盲孔111的开口朝向连接部201。盲孔111内设置有固化胶，连接部201的至少一部分伸入盲孔111中的固化胶内，以实现显示组件220与第二连接面B的连接。For example, as shown in FIG. 2, the display assembly 220 further includes a connecting portion 201 for connecting with the housing 100, for example, connecting with the second connecting surface B. The connecting portion 201 is located on a side of the display assembly 220 facing the second connecting surface B and protrudes toward the second connecting surface B. Blind holes 111 are opened on the bottom plate 110 of the housing where the second connecting surface B is located, corresponding to the connecting portion 201 one by one, and the opening of the blind hole 111 faces the connecting portion 201. Curing glue is arranged in the blind hole 111, and at least a part of the connecting portion 201 extends into the curing glue in the blind hole 111 to realize the connection between the display assembly 220 and the second connecting surface B.
例如，如图2所示，连接部201靠近盲孔111的一端包括中心孔202。当连接部201伸入到盲孔111中后，一部分固化胶可以进入中心孔202内，与中心孔202的至少部分表面接触。如此，可以增加连接部与固化胶的接触面积，增大结合强度。For example, as shown in FIG. 2, one end of the connecting portion 201 close to the blind hole 111 includes a central hole 202. After the connecting portion 201 extends into the blind hole 111, a part of the cured glue can enter the central hole 202 and contact at least part of the surface of the central hole 202. In this way, the contact area between the connecting portion and the cured adhesive can be increased, and the bonding strength can be increased.
例如，虽然图2中示出的连接部包括中心孔，但是连接部也可以为实心的部件，不包括中心孔。For example, although the connecting part shown in FIG. 2 includes a central hole, the connecting part may also be a solid part, excluding the central hole.
虽然图2示出连接部201的数量为2个，但是连接部201的数量也可以为1个或三个以上。图3A为根据本公开一实施例的显示组件及其连接部的侧视结构示意图，图3B为图3A所示的显示组件及其连接部沿E方向(大致与显示组件的显示面垂直的方向)的投影结构示意图。例如，如图3A和图3B所示，连接部201的数量为3个，3个连接部201在显示组件220的底面上呈三角形分布。相应地，盲孔111的数量也为3个，盲孔111在底板110上的分布与连接部201在显示组件220底面上的分布相同。需要说明的是，图3B所示的连接部在显示组件上呈三角形分布仅为一示例，连接部也可以沿一条直线分布或其他任意合适的方式分布。Although FIG. 2 shows that the number of connecting parts 201 is two, the number of connecting parts 201 may be one or more than three. 3A is a schematic side view of the structure of the display assembly and its connecting portion according to an embodiment of the present disclosure, and FIG. 3B is the display assembly and its connecting portion shown in FIG. 3A along the E direction (approximately perpendicular to the display surface of the display assembly) ) Is a schematic diagram of the projection structure. For example, as shown in FIGS. 3A and 3B, the number of connecting parts 201 is three, and the three connecting parts 201 are distributed in a triangular shape on the bottom surface of the display assembly 220. Correspondingly, the number of blind holes 111 is also three, and the distribution of the blind holes 111 on the bottom plate 110 is the same as the distribution of the connecting portion 201 on the bottom surface of the display assembly 220. It should be noted that the triangular distribution of the connecting parts shown in FIG. 3B on the display assembly is only an example, and the connecting parts may also be distributed along a straight line or in any other suitable manner.
例如，图4为图2中的D处(连接部与第二连接面的连接处)的一种结构示意图。如图4所示，连接部201为圆柱状，盲孔111的孔径大于连接部201的圆柱直径，如此设置便于将连接部***盲孔中。For example, FIG. 4 is a schematic diagram of a structure at D (the connection between the connecting portion and the second connecting surface) in FIG. 2. As shown in FIG. 4, the connecting portion 201 is cylindrical, and the hole diameter of the blind hole 111 is larger than the cylindrical diameter of the connecting portion 201. This arrangement facilitates the insertion of the connecting portion into the blind hole.
当然，连接部201也可以为其他形状，盲孔111的孔径大于连接部201伸入所述盲孔中的部分沿平行于第二连接面B的平面截取的截面的最大尺寸。Of course, the connecting portion 201 may also have other shapes, and the aperture of the blind hole 111 is larger than the maximum size of the cross section of the part of the connecting portion 201 that extends into the blind hole, which is taken along a plane parallel to the second connecting surface B.
例如，如图4所示，连接部201与盲孔111的侧壁和底面均不直接接触，且连接部与盲孔的侧壁和底面之间具有填充固化胶的间隙，如此设置可以保证连接部不会因为与凹槽的侧壁或底面彼此之间的相互作用力而产生内部应 力，从而避免出现画面显示不均的现象。For example, as shown in Figure 4, the connecting portion 201 is not in direct contact with the sidewall and bottom surface of the blind hole 111, and there is a gap filled with curing glue between the connecting portion and the sidewall and bottom surface of the blind hole. This arrangement can ensure the connection The part will not generate internal stress due to the interaction force between the side wall or bottom surface of the groove, so as to avoid the phenomenon of uneven display of the picture.
连接部与盲孔的侧壁和底面之间的间隙决定了连接部与盲孔之间允许的配合误差。通过设置合适的连接部与盲孔的侧壁间隙数值，可以调整由于盲孔在第二连接面上的位置误差造成的在平行于第二连接面方向上连接部与盲孔之间允许的配合误差；通过设置合适的连接部与盲孔的底面之间的间隙数值，可以调整由于第一连接面和第二连接面的距离误差或平行度误差等误差造成的在垂直于第二连接面方向上连接部与盲孔之间允许的配合误差。The gap between the side wall and bottom surface of the connecting part and the blind hole determines the allowable fit error between the connecting part and the blind hole. By setting the appropriate value of the gap between the side wall of the connecting part and the blind hole, the allowable fit between the connecting part and the blind hole in the direction parallel to the second connecting surface caused by the position error of the blind hole on the second connecting surface can be adjusted Error; by setting the appropriate value of the gap between the connection part and the bottom surface of the blind hole, the distance error or parallelism error between the first connection surface and the second connection surface can be adjusted in the direction perpendicular to the second connection surface The allowable fit error between the upper connecting part and the blind hole.
例如，对于图2所示的显示设备，连接显示装置200与壳体100的步骤包括：采用滴注等方式向盲孔111注入液态的固化胶；在第一连接面A上或盖板210的伸出到显示组件220的边缘的外侧的环形部分上贴双面胶带，将显示装置200放入壳体100内，并使盖板与第一连接面粘接牢固，以确定显示装置和壳体的相对位置，此时连接部的至少一部分伸入盲孔中的固化胶内；将显示装置以及壳体置于固化胶固化所需要的环境中以完成固化胶的固化。For example, for the display device shown in FIG. 2, the steps of connecting the display device 200 and the housing 100 include: injecting liquid curing glue into the blind hole 111 by means of dripping or the like; Stick a double-sided tape on the ring part protruding to the outside of the edge of the display assembly 220, put the display device 200 into the housing 100, and make the cover plate and the first connecting surface adhere firmly to confirm the display device and the housing At this time, at least a part of the connecting part extends into the curing glue in the blind hole; the display device and the casing are placed in the environment required for curing of the curing glue to complete the curing of the curing glue.
在图2所示的显示设备中，在显示装置与壳体的两个连接处中，盖板210与第一连接面A采用双面胶带连接，显示组件220与第二连接面B采用固化胶连接。然而，显示装置与壳体的两个连接处还可以采用其他组合连接方法。In the display device shown in FIG. 2, in the two connections between the display device and the housing, the cover 210 and the first connection surface A are connected by double-sided tape, and the display assembly 220 and the second connection surface B are connected by curing adhesive. connect. However, the two connections between the display device and the housing can also adopt other combined connection methods.
例如，显示组件220与第二连接面B采用固化胶连接，盖板210与第一连接面A也采用固化胶连接。如此，显示装置与第一连接面和第二连接面的连接均允许较大的配合误差，有利于避免连接处产生应力集中。For example, the display assembly 220 and the second connection surface B are connected by curing glue, and the cover 210 and the first connection surface A are also connected by curing glue. In this way, the connection between the display device and the first connection surface and the second connection surface allows a relatively large fit error, which is beneficial to avoid stress concentration at the connection.
又例如，盖板210与第一连接面A通过固化胶粘接，显示组件220与第二连接面B通过螺钉连接。螺钉连接结构可以参考图1A，连接部201为螺柱201，螺柱201包括内螺纹，壳体的底板110包括通孔，螺钉穿过通孔与连接部通过螺纹连接。如此，可以通过调整盖板与第一连接面的固化胶的使用量，来调整螺柱201与B面的距离，从而达到避免连接处产生应力集中的目的。For another example, the cover 210 and the first connection surface A are bonded by curing glue, and the display assembly 220 and the second connection surface B are connected by screws. For the screw connection structure, refer to FIG. 1A. The connecting portion 201 is a stud 201, the stud 201 includes an internal thread, the bottom plate 110 of the housing includes a through hole, and the screw passes through the through hole and is connected to the connecting portion by a thread. In this way, the distance between the stud 201 and the B surface can be adjusted by adjusting the usage amount of the curing glue of the cover plate and the first connection surface, so as to achieve the purpose of avoiding stress concentration at the connection.
又例如，盖板210与第一连接面A通过固化胶粘接，显示组件220与第二连接面B通过接触连接，接触连接结构可以参考图1B，连接部201为朝向底板110的凸台201，凸台201通过与底板110接触来支撑显示组件220。如此，可以通过调整盖板与第一连接面的固化胶的使用量，来调整凸台201与B面的距离，从而达到避免连接处产生应力集中的目的。For another example, the cover 210 and the first connecting surface A are bonded by curing glue, and the display assembly 220 and the second connecting surface B are connected by contact. For the contact connection structure, refer to FIG. 1B. The connecting portion 201 is a boss 201 facing the bottom plate 110. , The boss 201 supports the display assembly 220 by contacting the bottom plate 110. In this way, the distance between the boss 201 and the B surface can be adjusted by adjusting the usage amount of the curing glue of the cover plate and the first connection surface, so as to achieve the purpose of avoiding stress concentration at the connection.
总之，在盖板210与第一连接面A之间和显示组件220与第二连接面B之间这两个连接处中，至少一个连接处需要采用固化胶连接。如此，可以防止显示装置在连接处产生应力集中，从而避免出现画面显示不均的现象。In short, at least one of the two connections between the cover 210 and the first connection surface A and between the display assembly 220 and the second connection surface B needs to be connected by curing glue. In this way, it is possible to prevent the display device from generating stress concentration at the connection, thereby avoiding the phenomenon of uneven display of the picture.
对于上述显示装置与机壳的其他连接方法，其连接步骤与图2所示的连接显示装置与壳体的步骤类似，此处不再详细描述。For other connection methods of the above-mentioned display device and the casing, the connection steps are similar to the steps of connecting the display device and the casing shown in FIG. 2, and will not be described in detail here.
例如，盖板210的材料可以为玻璃材料或透明有机材料。For example, the material of the cover plate 210 may be a glass material or a transparent organic material.
例如，盖板210与显示组件220通过光学胶230粘接在一起。例如，光学胶230也可以为OCR胶。For example, the cover 210 and the display assembly 220 are bonded together by optical glue 230. For example, the optical glue 230 may also be an OCR glue.
例如，显示组件220为液晶显示组件。如图2所示，显示组件220包括在从盖板210到第二连接面B的方向依次层叠设置的液晶显示面板221和背光源222。例如，显示组件220还包括用于支撑显示面板221的中框223和用于容纳背光源222的背板224。液晶显示面板221与盖板210通过光学胶230粘接，背光源222位于液晶显示面板221远离盖板210的一侧。例如，背板224为环形凹槽结构，背光源222位于背板222的环形凹槽内。背板224的底板位于背光源222远离液晶显示面板221的一侧。For example, the display component 220 is a liquid crystal display component. As shown in FIG. 2, the display assembly 220 includes a liquid crystal display panel 221 and a backlight 222 that are sequentially stacked in a direction from the cover 210 to the second connection surface B. For example, the display assembly 220 further includes a middle frame 223 for supporting the display panel 221 and a back plate 224 for accommodating the backlight source 222. The liquid crystal display panel 221 and the cover plate 210 are bonded by optical glue 230, and the backlight source 222 is located on the side of the liquid crystal display panel 221 away from the cover plate 210. For example, the back plate 224 has an annular groove structure, and the backlight 222 is located in the annular groove of the back plate 222. The bottom plate of the back plate 224 is located on the side of the backlight source 222 away from the liquid crystal display panel 221.
例如，连接部201的一端与背板224固定连接，另一端朝向第二连接面B凸出。For example, one end of the connecting portion 201 is fixedly connected to the back plate 224, and the other end protrudes toward the second connecting surface B.
例如，如图2所示，背光源222包括层叠设置的导光板2221和光学膜片2222，光学膜片2222位于导光板2221靠近显示面板221的一侧。导光板2221和光学膜片2222均与中框223卡位嵌合。例如，光学膜片2222包括扩散膜、增亮膜和偏光型增亮膜等膜片。For example, as shown in FIG. 2, the backlight source 222 includes a light guide plate 2221 and an optical film 2222 that are stacked, and the optical film 2222 is located on a side of the light guide plate 2221 close to the display panel 221. The light guide plate 2221 and the optical film 2222 are both engaged with the middle frame 223 in a clamping position. For example, the optical film 2222 includes films such as a diffusion film, a brightness enhancement film, and a polarization-type brightness enhancement film.
显示组件的各组成部分以及盖板共同组成了显示装置200。例如，显示装置200为液晶显示器。The various components of the display assembly and the cover plate together constitute the display device 200. For example, the display device 200 is a liquid crystal display.
例如，显示装置200也可以为有机发光二极管(OLED)显示装置或量子点发光二极管(QLED)显示装置等，相应的显示组件220包括OLED显示面板或QLED显示面板，而不需要包括背光源。本公开的实施例不限定显示装置的具体类型。For example, the display device 200 may also be an organic light emitting diode (OLED) display device or a quantum dot light emitting diode (QLED) display device, etc. The corresponding display assembly 220 includes an OLED display panel or a QLED display panel, and does not need to include a backlight source. The embodiment of the present disclosure does not limit the specific type of the display device.
例如，双面胶带301可以为泡棉双面胶带，具有粘接强度高的优点。For example, the double-sided tape 301 may be a double-sided foam tape, which has the advantage of high bonding strength.
图5为图2所示的显示设备沿图中C方向的投影结构示意图。C方向为垂直于盖板210的方向。例如，如图5所示，显示装置200沿C方向观察的 平面形状为具有圆角的矩形。需要说明的是，显示装置的形状也可以为其他形状，例如为圆形或由多条线拼接围绕形成的不规则平面图形。相应地，壳体的平面形状与显示装置类似。本公开不限定显示装置和壳体的平面形状。另外，图5中示出了壳体100的外缘部140。但是，壳体也可以不包括外缘部，此时显示装置和壳体沿C方向的投影视图可以基本重合，本公开不再提供附图说明。FIG. 5 is a schematic diagram of the projection structure of the display device shown in FIG. 2 along the direction C in the figure. The C direction is a direction perpendicular to the cover plate 210. For example, as shown in FIG. 5, the planar shape of the display device 200 viewed in the C direction is a rectangle with rounded corners. It should be noted that the shape of the display device may also be other shapes, such as a circle or an irregular plane figure formed by splicing and surrounding a plurality of lines. Correspondingly, the planar shape of the housing is similar to that of the display device. The present disclosure does not limit the planar shape of the display device and the housing.
