[0025] The utility model will be further illustrated in combination with specific embodiments, and the embodiments are implemented on the premise of the technical scheme of the utility model, and it should be understood that the embodiments are only used for illustrating the utility model and are not used for limiting the scope of the utility model.

[0026] As Figures 1-6As shown, the small household appliance ultra-thin display screen comprises a display module 1, a window 2, a support 3, and a supporting piece 4 and the like, the display module 1 is fixedly connected with the window 2 at one side of the front face, and is connected with the support 3 at the other side of the back face through the supporting piece 4. The upper surface of the display module 1 is attached to the back face of the window 2, and the display module 1 and the window 2 are adhesively fixed.

[0027] In the embodiment, the window 2 is a light-transmitting flat piece, and the display module 1 can be controlled by touching through the window 2. The material of the window 2 is acrylic, glass, an injection-molded-in-film piece (IMD) or other injection-molded pieces (made of ABS, PC or ABS+PC material).

[0028] The support 3 is a supporting and mounting piece of the display module 1 and the window 2, the support 3 is open at the upper portion and forms a containing cavity 32 for containing the display module 1 and the window 2, a sunken groove 31 is formed in the upper surface of the support 3 at the outer periphery of the containing cavity 31 of the support 3, the depth of the groove 31 is substantially the same as the thickness of the window 2, the window 2 is adhesively fixed in the groove 31, so that the upper surface of the window 2 is flush with the upper surface of the support 3, and the integrity of the entire display screen is maintained.

[0029] The display module 1 adopts an ultra-thin display module 1, which comprises, from bottom to top, a circuit board 11, a light guide plate 12, a light-blocking bubble cotton 13 and a diaphragm 14. The light-blocking bubble cotton 13 is located at the outer periphery of the light guide plate 12, and plays a role of light blocking between the light guide plates 12 and the outer periphery, and is also used for supporting the diaphragm 14 of the upper layer. Since the diaphragm 14 is relatively thin, the flatness of the diaphragm 14 can be ensured. The lower surface of the diaphragm 14 is adhesively fixed with the light guide plate 12 and the light-blocking bubble cotton 13, and the upper surface is tightly attached to the back face of the window 2.

[0030] The area of the display module 1 is smaller than the area of the window 2, and the display module is relatively thin. The display module 1 and the window 2 are adhesively fixed through the form of glue injection between the outer periphery of the display module 1 and the window 2, which can realize the fixed connection of the two and the waterproof of the upper surface of the display module 1 at the same time.

[0031] There can be various glue injection modes, and two modes are listed in the embodiment.

[0032] The first mode is to directly inject glue in the triangular area formed between the display module 1 and the window 2 to fix the two, and the glue injection forms a sealing strip 5, as shown in Figure 2 .

[0033] The second mode is to integrally form a retaining ring 21 on the back face of the window 2, the display module is arranged in the retaining ring 21, a gap is left between the display module 1 and the retaining ring, and glue is injected in the gap to form a glue injection layer, so as to realize sealing and fixing, as shown in Figure 3 .

[0034] The supporting pieces 4 are uniformly arranged on the back face of the display module 1, and the supporting pieces 4 are hard supports or soft supports, which support the display module 1 and the window 2.

[0035] Support 4 is a soft support made of foam or rubber, and the foam has a large density and elasticity. Preferably, a soft support is used, and support 4 is arranged on the back of the circuit board 11 of the display module 1, avoids the circuit elements, and is arranged around the outer periphery of the circuit elements. The height of support 4 is greater than the height of the electronic elements, and support 4 also protects the electronic elements. Support 4 can be provided with a plurality of supports distributed at different positions, so that the display module 1 and the window 2 are uniformly stressed.

[0036] The assembling steps of the display module according to the present application are as follows:

[0037] Step 1: Assemble the display module and debug it to ensure that the display and touch control functions are good.

[0038] Step 2: Invert the display module on the back of the window 2, and glue around the outer periphery of the display module 1 to fix and seal the display module 1 and the window 2.

[0039] Step 3: Apply glue to the groove 31 of the bracket 3, and bond the window 2 to the bracket 3, and at the same time, the display module 1 enters the accommodating cavity 32 of the bracket 3.

[0040] The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
