[0040] This utility model discloses a display module, a smart host, and a smart wearable device. The display module adopts a non-full-surface touch design, which can reduce the cost of the display module.

[0041] Example 1

[0042] Please see Figures 1 to 3 This is a schematic diagram of the structure of a display module 100 provided in Embodiment 1 of the present utility model. The display module 100 includes a display component 20, a touch circuit board 30, and a glass cover plate 40. The display component 20 has a display area, and the touch circuit board 30 includes a touch part 31. The touch part 31 is disposed on one side of the display component 20, and the projection of the touch part 31 on the display component 20 is located on the periphery of the display area. The glass cover plate 40 covers the side of the touch part 31 away from the display component 20.

[0043] In this embodiment, the touch portion 31 of the touch circuit board 30 is provided on one side of the display component 20, and a glass cover plate 40 is used to cover the side of the touch portion 31 facing away from the display component 20. In this way, the user can view the content displayed in the display area of ​​the display component 20 through the glass cover plate 40 and can also perform touch operations. Furthermore, the projection of the touch portion 31 on the display component 20 is located on the periphery of the display area, so the display module 100 is designed as a non-full-area touch device. Compared with a full-area touch design, the display area of ​​the display component 20 and the coverage area of ​​the touch portion 31 can be reduced at the same time, thereby reducing the materials used in the display component 20 and the touch circuit board 30, and thus reducing the cost of the display module 100.

[0044] In some embodiments, the display module 100 further includes a bracket 10, with the display component 20 disposed on one side of the bracket 10, the touch unit 31 disposed on the side of the bracket 10 opposite to the display component 20, and a glass cover plate 40 disposed on the side of the bracket 10 opposite to the display component 20. Thus, by placing the display component 20 on one side of the bracket 10 and the touch unit 31 of the touch circuit board 30 on the side of the bracket 10 opposite to the display component 20, the bracket 10 provides assembly and support for the display component 20 and the touch unit 31, while also separating them to prevent short circuits between the display component 20 and the touch unit 31.

[0045] For example, the glass cover 40 has a light-transmitting portion 41 and a non-light-transmitting portion 42 disposed around the light-transmitting portion 41. The light-transmitting portion 41 is disposed corresponding to the display area, and the non-light-transmitting portion 42 is disposed corresponding to the touch portion 31. In this way, by using the light-transmitting portion 41 of the glass cover 40 to correspond to the display area and the non-light-transmitting portion 42 to correspond to the touch portion 31, the user can view the content displayed in the display area of ​​the display component 20 through the non-light-transmitting portion 42, and can also perform touch operations through the non-light-transmitting portion 42.

[0046] The non-transparent portion 42 of the glass cover plate 40 can be made of an opaque material or a light-shielding layer can be coated on the corresponding position of the glass cover plate 40. The light-shielding layer can be black ink or black adhesive, etc., and can be selected according to the actual situation. This embodiment does not make specific limitations on this.

[0047] Optionally, to ensure that users can clearly identify the corresponding control content when performing touch operations, such as page turning, switching application windows, or opening and closing application windows, markings, such as silkscreened white marks or patterns, can be provided on the non-transparent part 42, and these markings can correspond to the touch part 31.

[0048] Among them, the function keys marked on the non-transparent part 42 that correspond to the touch part 31 may include start / stop key (S key), volume keys (+ key, - key), left / right switch key (L key, R key), etc. This embodiment does not make specific limitations on this.

[0049] In some embodiments, such as Figure 2 As shown, the touch unit 31 is configured in a semi-circular shape, and the projection of the touch unit 31 on the display assembly 20 extends along the edge of the display area. In this way, the coverage area of ​​the touch unit 31 can be further reduced, thereby reducing the material used in the touch circuit board 30 and lowering the cost of the display module 100.

[0050] In some other embodiments, the touch unit 31 is configured in a ring shape, and the projection of the touch unit 31 on the display component 20 surrounds the display area. In this way, the function keys corresponding to the touch unit 31 can be distributed around the display area, which facilitates touch operation by the user, and the number of function keys can be set to be large, increasing the richness of the display module operation.

[0051] In some embodiments, the display component 20 includes a display circuit board 21 and a plurality of LED beads 22. The display circuit board 21 is disposed on one side of the bracket 10, and the plurality of LED beads 22 are arranged in an array on the display circuit board 21 and electrically connected to the display circuit board 21. The area on the display circuit board 21 where the plurality of LED beads 22 are distributed forms a display area. The bracket 10 is provided with a plurality of through slots 11, each of which accommodates a plurality of LED beads 22. In this way, on the one hand, by arranging the plurality of LED beads 22 in an array on the circuit board, the circuit board drives the plurality of LED beads 22 to emit light, and the light can pass through the light-transmitting part 41 of the glass cover plate 40, thereby allowing the user to view the content displayed by the display module 100. On the other hand, by using the plurality of through slots 11 of the bracket 10 to accommodate the plurality of LED beads 22, the plurality of LED beads 22 are shielded from light, preventing cross-lighting between the plurality of LED beads 22 and improving the display effect of the display module 100.

[0052] For example, such as Figure 4 As shown, the through slot 11 includes a first slot 11a and a second slot 11b that are interconnected. The second slot 11b extends through the bracket 10 to the side facing the display circuit board 21 and is square in shape. The first slot 11a extends through the bracket 10 to the side facing the glass cover plate 40 and is round in shape. Each LED bead 22 is configured to match the shape of the second slot 11b, and multiple LED beads 22 are respectively housed in multiple second slots 11b. In this way, on the one hand, by configuring each LED bead 22 to match the shape of the second slot 11b, and using multiple second slots 11b to house multiple LED beads 22, multiple LED beads 22 can be positioned and assembled. On the other hand, the light from the LED beads 22 that passes through the first slot 11a is round in shape with clear edges, which can improve the display effect of the screen.

[0053] In some embodiments, such as Figure 5As shown, the bracket 10 has a receiving groove 12 on the side facing the glass cover plate 40. The display module 100 also includes a light-diffusing film 50, which is disposed in the receiving groove 12, and the projection of the light-diffusing film 50 on the bracket 10 covers the display area. In this way, on the one hand, the light-diffusing film 50 is used to homogenize the light emitted by the multiple LED beads 22, resulting in more uniform light on the display screen and improving the user's viewing experience. On the other hand, after the light-diffusing film 50 homogenizes the light emitted by the multiple LED beads 22, the distance between the LED beads 22 and the glass cover plate 40 can be designed to be closer, reducing the overall thickness of the display module 100. Furthermore, by using the receiving groove 12 to house the light-diffusing film 50, the space occupied by the light-diffusing film 50 can be reduced, thereby reducing the overall thickness of the display module 100.

[0054] For example, the support 10 has a protrusion 10a on the side facing the glass cover plate 40. The protrusion 10a is configured in a ring shape to form a receiving groove 12 on the inner peripheral side of the protrusion 10a, and the touch part 31 is located on the outer peripheral side of the protrusion 10a. In this way, by providing a protrusion 10a on the side of the support 10 facing the glass cover plate 40 and configuring the protrusion 10a in a ring shape, a receiving groove 12 can be formed on the inner peripheral side of the protrusion 10a, thereby placing the light-diffusing film 50 on the inner peripheral side of the protrusion 10a. Furthermore, the touch part 31 is located on the outer peripheral side of the protrusion 10a. While the protrusion 10a separates the light-diffusing film 50 and the touch part 31, it also ensures that the light-diffusing film 50 and the touch part 31 do not overlap in the thickness direction of the display module 100, avoiding the situation where the space occupied by the two in the thickness direction overlaps, thereby reducing the space occupied by the two in the thickness direction and making the overall thickness of the display module 100 smaller.

[0055] In some embodiments, such as Figure 2 and Figure 6 As shown, the display module 100 also includes a first adhesive layer 61 and a second adhesive layer 62. The first adhesive layer 61 is bonded to the side of the bracket 10 facing the glass cover plate 40, and the side of the first adhesive layer 61 away from the bracket 10 is bonded to the glass cover plate 40. The second adhesive layer 62 is bonded to the side of the touch unit 31 facing the glass cover plate 40, and the side of the second adhesive layer 62 away from the touch unit 31 is bonded to the glass cover plate 40. In this way, by bonding the second adhesive layer 62 to the side of the touch unit 31 facing the glass cover plate 40 and the side of the second adhesive layer 62 away from the touch unit 31 to the glass cover plate 40, the touch unit 31 and the glass cover plate 40 are tightly bonded, improving the touch sensitivity and accuracy of the non-transparent portion 42 of the glass cover plate 40. On the other hand, the first adhesive layer 61 is bonded to one side of the glass cover plate 40 of the bracket 10, and the side of the first adhesive layer 61 away from the bracket 10 is bonded to the glass cover plate 40. Thus, the glass cover plate 40 can be bonded to the bracket 10 through the first adhesive layer 61 and the second adhesive layer 62, which can improve the connection strength between the glass cover plate 40 and the bracket 10.

[0056] For example, the first adhesive layer 61 is configured in a ring shape, and the projection of the first adhesive layer 61 on the bracket 10 surrounds the projection of the second adhesive layer 62 on the bracket 10 and the display area. In this way, by configuring the first adhesive layer 61 in a ring shape and bonding it between the bracket 10 and the glass cover plate 40, a sealing design is achieved between the bracket 10 and the glass cover plate 40. Simultaneously, since the projection of the first adhesive layer 61 on the bracket 10 surrounds the projection of the second adhesive layer 62 on the bracket 10 and the display area, components related to the second adhesive layer 62 and the display area, such as the touch unit 31 and the light-diffusing film 50, can be distributed within the sealed area between the bracket 10 and the glass cover plate 40, preventing damage to these components from water, dust, or other foreign matter.

[0057] In some embodiments, the display module 100 further includes a third adhesive layer 63, which is bonded between the bracket 10 and the touch unit 31. By providing the third adhesive layer 63 between the bracket 10 and the touch unit 31, the touch unit 31 is bonded to the bracket 10, thereby fixing the touch unit 31 and ensuring that its relative position to the bracket 10 and the glass cover 40 remains unchanged. This prevents changes in the position of the touch unit 31 from causing abnormalities or even failures in the touch function of the display module 100.

[0058] For example, the bracket 10 has a notch 13 on its periphery, and the touch circuit board 30 also includes a power receiving part 32. The power receiving part 32 extends from the touch part 31 through the notch 13 to the side of the bracket 10 facing the display circuit board 21 and is electrically connected to the display circuit board 21. In this way, by providing a notch 13 on the periphery of the bracket 10, the power receiving part 32 is allowed to extend from the touch part 31 through the notch 13 to the side of the bracket 10 facing the display circuit board 21 and be electrically connected to the display circuit board 21. Furthermore, by electrically connecting the power receiving part 32 to the display circuit board 21, the touch circuit board 30 and the display circuit board can be integrated through wiring. Therefore, when the display module 100 is used in electronic products such as smart wearable devices, the difficulty of electrically connecting the display module 100 to the motherboard of the electronic product is reduced.

[0059] This utility model provides a display module 100. A touch unit 31 of a touch circuit board 30 is disposed on one side of a display component 20. A glass cover 40 is used to cover the side of the touch unit 31 facing away from the display component 20. Thus, the user can view the content displayed on the display area of ​​the display component 20 through the glass cover 40 and also perform touch operations. Furthermore, the projection of the touch unit 31 onto the display component 20 is located on the periphery of the display area, thereby designing the display module 100 as a non-full-area touch module. Compared to a full-area touch module design, this reduces both the display area of ​​the display component 20 and the coverage area of ​​the touch unit 31, thereby reducing the materials used in the display component 20 and the touch circuit board 30, and ultimately lowering the cost of the display module 100.

[0060] Example 2

[0061] Please see Figures 7 to 9 This is a schematic diagram of the structure of a smart host 200 provided in Embodiment 2 of the present utility model. The smart host 200 includes a housing 201, a motherboard 202, and a display module 100 in Embodiment 2. The housing 201 has a receiving cavity 201a and an opening 201b communicating with the receiving cavity 201a. The motherboard 202 is disposed in the receiving cavity 201a. The display module 100 is covered by the opening 201b and is electrically connected to the motherboard 202.

[0062] This utility model provides a smart host 200, and the display module 100 adopts a non-full-surface touch design, which can reduce the cost of the display module 100.

[0065] Embodiment 3 of this utility model provides a smart wearable device 300. The display module adopts a non-full-surface touch design, which can reduce the cost of the display module and the overall thickness of the display module is small, thus realizing the lightweight design of the smart wearable device 300.
