Corresponding numbers can also be silkscreened on the corresponding positions on the first circuit board 34 for easier installation. Each light guide plate 33 is provided with at least two light guide plate positioning posts 35 to achieve precise positioning and prevent tilting or misalignment during installation. Example 2

[0040] This embodiment discloses an arc-shaped combined display module. It is designed for home appliance panels that include mechanical knobs, thick lamp cavity display units, power switches, digital tubes, etc., and require some ultra-thin large background display modules. When various designs are integrated on the same display panel, it is necessary to combine components of different thicknesses in one display module, and the parts in contact with the panel must be of uniform height.

[0041] An arc-shaped combined display module includes an arc-shaped display module support 5, a first display control component 30, and a second display control component 40 with a thickness greater than that of the first display control component 30. The first display control component 30 adopts the arc-shaped ultra-thin display control module of Embodiment 1 or other various types of arc-shaped ultra-thin display control modules.

[0042] The curved combined display module uses a display module bracket 5 to combine display modules and components of different heights. One side of the display module bracket 5 is provided with a first display control component 30 (curved ultra-thin display control module), and the other side is provided with a second display control component 40 with a thickness greater than the first display control component 30. The upper surface of the display module bracket 5 can also be set as curved.

[0043] like Figure 1 As shown, the second display and control component 40, whose height is greater than that of the curved ultra-thin display control module, may include a knob, a digital tube, a lamp cavity display unit 41, a second diaphragm 42, a second circuit board 43, etc. The horizontal height of the second circuit board 43 is lower than that of the first circuit board 34, and the two are electrically connected through a pin 44. Light sources 6 are provided on both the first circuit board 34 and the second circuit board 43. The back of the second circuit board 43 can also be fully potted to achieve sealing and waterproofing of the entire circuit board, improving the waterproofing effect.

[0044] The display module bracket 5 shown in the figure is only a structure for demonstration purposes in this embodiment, and can be modified according to the user's design. Example 3

[0045] This embodiment discloses a planar combined display module. The difference from the previous embodiment is that the curved ultra-thin display control module is replaced with a planar ultra-thin display control module, and the display module support 5 is also planar. Other structures are the same and will not be described further.

[0046] The planar display module includes a display module bracket 5, a planar ultra-thin display control module, and a second display control component 40 with a thickness greater than the first display control component 30 (which uses the planar ultra-thin display control module). The planar ultra-thin display control module adopts an ultra-realistic ultra-thin display module as described in application number 202223539772.1. When applied to a washing machine, the back of the planar ultra-thin display control module can be sealed with potting compound to waterproof the entire circuit board. Alternatively, various other types of planar ultra-thin display control modules can be used.

[0047] A first display control component 30 (using a flat ultra-thin display control module) is mounted on one side of the flat display module bracket 5, and a second display control component 40 with a thickness greater than that of the first display control component 30 is mounted on the other side. The second display control component 40, which is taller than the flat ultra-thin display control module, can be the second display control component 40 described in Embodiment 2. Example 4

[0048] like Figures 3-11 As shown, this embodiment provides a combined display device with a sealed structure, including a display module 1 and a first panel assembly 2. The display module 1 is connected to and sealed with the first panel assembly 2. The sealing of the display module 1 and the first panel assembly 2 is a back seal and a front seal.

[0049] If the panel assembly is curved, with a higher center and lower sides, the cross-section is curved. In order to ensure a tight fit between the display module and the curved panel and improve touch sensitivity, the display module 1 adopts the curved ultra-thin display control module of Embodiment 1, or the curved combined display module of Embodiment 2.

[0050] If the panel assembly is a flat panel, then the flat ultra-thin display control module of Embodiment 3 or the flat combined display module of Embodiment 3 shall be used.

[0051] like Figure 9 As shown, in this embodiment, the panel assembly adopts a first panel assembly 2, which includes a first front control panel bracket 21, a panel bracket 22, and a first display window 23. The first display window 23 is disposed on the front of the panel bracket 22, and the two are combined together. The first display window 23 is made of acrylic, glass, in-mold molding (IMD), or other injection molded parts (using ABS, PC, or ABS+PC materials). The first display window 23 can clearly display the content of the display module 1, and the display module 1 can be controlled by touch through the acrylic or glass panel.

[0052] like Figure 8As shown, a first enclosure 25 is provided on the back of the panel bracket 22, and the first display window 23 is located inside the first enclosure 25. The panel bracket 22 can be made by injection molding or mold making. The space inside the first enclosure 25 is used for embedding and installing the display module 1. The first panel assembly 2 can also be provided with a buckle 26 for fixed connection with the first front control panel bracket 21.

[0053] like Figure 7 As shown, the combined display module 1 is sealed to the panel bracket 22 and the first display window 23 disposed within the panel bracket 22. The panel bracket 22 is connected to the first front control panel bracket 21. The display module bracket 5 and the panel bracket 22 enclose each other to form a first sealing groove 24, and a sealing ring or potting compound is disposed within the first sealing groove 24 to form a sealing layer. Specifically, a first enclosure 25 is provided on the panel bracket 22, the combined display module 1 is located within the first enclosure 25, and the first sealing groove 24 is formed by the display module bracket 5 and the first enclosure 25.

[0054] In this embodiment, as Figure 7 As shown, the back seal between the display module 1 and the panel assembly is achieved by either using a sealing ring or potting compound. The sealing ring or potting compound is placed within the first sealing groove 24. If a sealing ring is used, it is interference-fitted with the inner wall of the first sealing groove 24, securing the ring within the groove. This can be achieved by screws or adhesive. If potting compound forms a waterproof layer, it is evenly injected into the retaining ring after the ultra-thin display control module 2 is installed, with a thickness of approximately 3mm to 5mm. The waterproof compound can be polyurethane sealant or silicone, etc.

[0055] like Figure 6 As shown, the display module 1 and the first panel assembly 2 are provided with positioning components 14 and screw locking components 13 to achieve positioning and fixation of the display module 1. The display module 1 and the panel assembly are fixed by screw locking components 13, or by snap-fit ​​connections, or by a combination of screw locking components 13 and snap-fit ​​connections. Snap-fit ​​connections are the conventional type and are not shown in the figure.

[0056] Front sealing involves applying adhesive to the upper surface of the combined display module 1 and bonding and sealing it to the inner surface of the panel assembly. For example, the first diaphragm 31 can be bonded and fixed to the first display window 23, or a foam layer can be provided around the outer periphery of the first diaphragm 31, with the foam layer serving as the bonding medium.

[0057] After the display module 1 is assembled, the front is sealed first. First, glue is applied to the surface of the display module 1 or the inner surface of the panel. Then, it is installed and glued to the back of the first panel assembly 2 inside the enclosure 21. After being locked by screws 13 or buckles, the upper surface of the display module 1 is in close contact with the acrylic or glass of the first panel assembly 2 to achieve highly sensitive touch control. Then, the back is sealed. First, glue is poured onto the circuit board on the back of the second display control assembly 40. Then, a sealing ring is installed in the first sealing groove 24 or glue is poured to form a waterproof layer. Example 5

[0058] like Figure 12 and 13 As shown, this embodiment provides a combined display device with a sealed structure, including a display module 1 and a second panel assembly 3. The display module 1 and the second panel assembly 3 are connected and sealed. The sealing of the display module 1 and the second panel assembly 3 is a back seal and a front seal.

[0059] The difference from Embodiment 5 lies in the form of the panel assembly. In this embodiment, the panel assembly is a second panel assembly 3, which omits the panel bracket. The second panel assembly 3 includes a second front control panel bracket 31 and a second display window 32 disposed within the second front control panel bracket 31. The combined display module 1 is sealed and connected to the second front control panel bracket 31 and the second display window 32.

[0060] The display module bracket 5 and the second front control panel bracket 31 enclose each other to form a second sealing groove 33. A second enclosure 311 is provided on the second front control panel bracket 31. The combined display module 1 is located inside the second enclosure 311. The second sealing groove 33 is formed by the display module bracket 5 and the second enclosure 311. A sealing ring or potting compound is provided inside the second sealing groove 33 to form a sealing layer.

[0061] The other structures are the same as those in Example 4, and will not be described again. Example 6

[0062] A home appliance employing a combined display device with a sealed structure, including but not limited to washing machines, refrigerators, dishwashers, water purifiers, tea dispensers, range hoods, water heaters, ovens, robot vacuums, air conditioners, or other home appliances.

[0063] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
