Referring to fig. 4 and 5, the terminal device 100 includes a display module 10, a housing 20, and a connecting body 30. The display module 10 and the housing 20 together form an external appearance surface of the terminal device 100, and the display module 10 and the terminal device 100 are hermetically connected by the connecting body 30, so that foreign matters such as dust and water from the outside are prevented from entering the terminal device 100 to contaminate the terminal device 100.

The display assembly 10 is used to display images and colors. The display modules 10 are typically stacked and interconnected by a multi-layer structure. The display assembly 10 at least comprises a display screen 11 and a transparent cover plate 13 which are stacked, and the display assembly 10 is approximately block-shaped.

The display screen 11 may be a Liquid Crystal Display (LCD) for display. The display screen 11 includes a display area I and a non-display area surrounding the display area I. The display area I is used for emitting light, and the non-display area is not used for emitting light.

The transparent cover 13 is stacked on one side of the display screen 11 and covers the display area I and the non-display area. The region of the transparent cover 13 corresponding to the display region I is a region capable of normally displaying images and colors, and the region of the transparent cover 13 corresponding to the non-display region and the region outside the non-display region form a black edge region II. The transparent cover 13 is located on the outer surface of the terminal device 100, and plays a role in protecting the display screen 11.

When the terminal device 100 is a mobile phone or a tablet computer, the display assembly 10 may include a liquid crystal display, a Touch Panel (TP, not shown), and a transparent cover 13. When the terminal device 100 is a desktop computer, the display assembly 10 may not include a touch panel. When the terminal device 100 includes a touch panel, the touch panel may be integrated in the display 11 (e.g. a liquid crystal display), or may be disposed between the display 11 and the transparent cover 13. In the present embodiment, the touch panel is integrated in the liquid crystal display. The specific type of the display assembly 10 is merely illustrative and not restrictive. In other embodiments, the specific type of display assembly 10 may be adjusted according to the specific type and requirements of the terminal device 100.

The display assembly 10 includes a first side surface 15, and the first side surface 15 is a surface of the display screen 11 and the transparent cover 13 along the stacking direction L of the display screen 11 and the transparent cover 13. Within the error tolerance, the display screen 11 and the transparent cover 13 face the same plane along the stacking direction L, thereby minimizing the black border region II.

The housing 20 includes a first body portion 21 and a second body portion 23, and the first body portion 21 is connected to the second body portion 23. The first body portion 21 extends in the stacking direction L and surrounds the periphery of the second body portion 23. The first body portion 21 and the second body portion 23 may be an integral structure, or may be formed by connecting at least two components. In the present embodiment, the first body portion 21 and the second body portion 23 are an integral structure.

The first body portion 21 and the second body portion 23 are enclosed to form a groove 25, the display module 10 is disposed in the groove 25, the display module 10 is disposed apart from the housing 20, and the transparent cover 13 is disposed on a side away from the second body portion 23.

The first body portion 21 includes a second side surface 212 extending along the stacking direction L, and the second side surface 212 faces the first side surface 15 and is spaced apart from the first side surface 15 to form a first gap 27. The connecting body 30 is located in the first gap 27, and the connecting body 30 is disposed around the first side surface 15 and connected to the second side surface 212 to hermetically connect the display module 10 and the housing 20, i.e. the connecting body 30 is disposed around the periphery of the display module 10 in a ring shape and connected to the housing 20, so as to prevent external impurities (such as dust, water, etc.) from entering the terminal device 100. Both the first side 15 and the second side 212 extend in the stacking direction L, i.e. the edge area of the display assembly 10 does not protrude over the housing 20, thereby reducing the black border area II.

The connection body 30 includes a first glue body 31, and the first glue body 31 integrally bonds the components (such as the transparent cover 13 and the display screen 11) of the display assembly 10. Since the display module 10 is formed by stacking a plurality of layers, the first side 15 of the display module 10 formed by stacking a plurality of layers may have an uneven structure, and the first glue 31 may fill a portion of the recessed area to prevent foreign materials from entering the display module 10 having a multi-layer structure.

In some embodiments, the first gel 31 may also bond the display assembly 10 and the housing 20 to seal the display assembly 10 and the housing 20. The first colloid 31 has certain elasticity and can play a role in buffering, so that the display assembly 10 is prevented from being damaged due to collision between the display assembly 10 and the shell 20; the terminal device 100 can also prevent the case 20 from pressing the display module 10 to break the display module 10 due to possible deformation of the case 20 during a collision or a fall.

The connecting body 30 may further include an elastic body 33, the elastic body 33 is connected to the first gel 31, the first gel 31 is connected to the first side surface 15, and the elastic body 33 is connected to the second side surface 212. The elastic body 33 has elasticity, and the elasticity of the elastic body 33 is greater than that of the first colloid 31, so that the sealing function and the buffering function can be further achieved. The elastomer 33 may be soft rubber, foam, or the like. The soft rubber may be Polyethylene (PE), Polypropylene (PP), etc. In this embodiment, the elastic body 33 is made of soft rubber.

The elastic body 33 may also be embedded in the first colloid 31 and/or the housing 20, i.e. the surface of the first colloid 31 and/or the housing 20 connected to the elastic body 33 is recessed in a direction away from the elastic body 33, so that the elastic body 33 is embedded in the first colloid 31 and/or the housing 20. The structural design can increase the connecting area of the elastic body 33 and the first colloid 31 and/or the shell 20, thereby increasing the connecting reliability; but also increase the difficulty of the external impurities entering the terminal device 100, thereby further preventing the external impurities from entering the terminal device 100.

The width of the recess of the first colloid 31 and/or the housing 20 in the stacking direction L and the depth of the recess facing away from the display module 10 can be adjusted as required. The wider the recess width or the deeper the recess depth is, the larger the connection area between the elastic body 33 and the first gel 31 and/or the housing 20 is, the more reliable the connection is, and the better the sealing performance is.

The elastic body 33 includes a base portion 331 and a connecting rib 332, and the connecting rib 332 is provided on the base portion 331 so as to extend toward the first colloid 31 and to surround the first colloid 31.

The base portion 331 is connected to the second side surface 212 of the first body portion 21, and at least a part of the base portion 331 may be embedded in the first body portion 21. The number of the connecting ribs 332 extending from the base portion 331 can be set according to the requirement, for example, one or more connecting ribs can be provided, i.e. the connecting rib can surround the first rubber body 31 for one or more circles. The more the number (i.e. the number of the surrounding circles) of the connecting ribs 332 is, the larger the connecting area between the elastic body 33 and the first colloid 31 is, the stronger the connection reliability is, and the better the sealing performance and the buffering performance are. In this embodiment, the number of the elastic bodies 33 wound on the first colloid 31 is one. In the present embodiment, at least a part of the base portion 331 is embedded in the first body portion 21, and there is one connecting rib 332 of the elastic body 33.

In assembling the terminal device 100, the elastic body 33 (e.g., soft rubber) may be injection molded on the first body 21; the display module 10 is placed in the recess 25 of the housing 20, and a liquid glue is injected between the first side 15 and the second side 212, and the glue is cured to form the bonding elastomer 33 and the first glue 31 of the display module 10.

In some embodiments, the terminal device 100 further includes a second glue body 35, and the second glue body 35 bonds the display assembly 10 and the housing 20 to increase the reliability of the connection between the display assembly 10 and the housing 20.

The second glue 35 is located in the second gap 29 and bonds the first connecting surface 17 and the second connecting surface 232, thereby connecting the display assembly 10 with the housing 20.

The second glue body 35 is located in the projection area of the non-display area of the display module 10, and the second glue body 35 is annular, so that the display area I of the display module 10 is prevented from being affected by the position of the second glue body 35 in the display area I, the bonding area between the second glue body 35 and the display module 10 and between the second glue body 35 and the housing 20 can be increased to the greatest extent, and the connection reliability between the display module 10 and the housing 20 is increased.
