[0047] Please refer to Figures 1 to 3 According to the display control assembly of the present application, the circuit board 100 is provided with a plurality of side light sources 110 on the first side; the light guide plate 200 is arranged on the first side of the circuit board 100, and the light guide plate 200 comprises a plurality of light guide portions 210 connected integrally, and further comprises a light blocking portion 220 surrounding at least part of each light guide portion 210; the light guide portion 210 is concave to form a mounting groove 230 for the side light source 110; the light guide portion 210 and the side light source 110 are arranged one by one; and the light blocking portion 220 is used to separate adjacent light guide portions 210.

[0048] According to the present application, the mounting groove 230 is concave in the light guide portion 210, and the side light source 110 is mounted in the mounting groove 230, which is equivalent to that the side light source 110 is at least partially embedded in the light guide plate 200; the side light source 110 emits light from the position of the mounting groove 230 to the light guide portion 210, so that the thickness of the display control assembly can be controlled, which is conducive to the popularization and use of the ultra-thin door body of the refrigerator.

[0049] Among them, the setting of the mounting groove 230 can ensure that the side light source 110 is flush with or even recessed relative to the surface of the light guide portion 210, and the thickness of the light guide portion 210 is increased. Of course, it is not excluded that the light guide portion 210 is partially protruding relative to the surface of the light guide portion 210.

[0050] According to the present application, the mounting groove 230 can be a blind groove to ensure that the light of the side light source 110 is emitted from the light emitting surface of the light guide plate 200. Of course, in the case that the cooperation between the side wall of the mounting groove 230 and the side light source 110 is reliable, it is also not excluded that the mounting groove 230 adopts a through groove. The light guide portion 210 and the light blocking portion 220 are integrally connected, which can facilitate manual installation.

[0051] According to the embodiment of the present application, the circuit board 100 is provided with the induction button 120 corresponding to at least part of the light guide part 210, so as to solve the defects of high cost and loose button of the IOT film button, thereby improving the structural stability of the display control assembly. Moreover, since the induction button 120 corresponds to at least part of the light guide part 210, the button can have a light effect. For example, all the induction buttons 120 can correspond to the light guide part 210, so that all the induction buttons 120 can trigger the light effect under stress.

[0052] According to the embodiment of the present application, the side light source 110 and the induction button 120 are integrated on the circuit board 100, which has a simple structure and high integration. The side light source 110 can be but is not limited to a LED side light source 110, the induction button 120 can be but is not limited to a capacitive touch button, and the circuit board 100 can be but is not limited to a PCB (printed circuit board 100). For example, the side light source 110 can be but is not limited to a LED side light source 110, an organic light emitting diode (OLED) light source, a fluorescent lamp or an incandescent lamp, etc.; the induction button 120 can be but is not limited to a capacitive touch button, a light-sensitive touch button, a resistance touch button, etc.; and the circuit board 100 can be but is not limited to a PCB, a ceramic circuit board 100, an aluminum substrate, etc. The capacitive touch button integrated on the PCB has high trigger sensitivity, and only needs to be lightly touched to trigger, without the need of pressing hard, so that the user can operate more easily and conveniently. The capacitive touch button on the PCB can be designed in various shapes to be integrated with the product appearance, thereby improving the appearance of the product. The light guide part 210 can also be designed in various shapes, which can be integrated with the product appearance, thereby improving the appearance of the product. In combination with Figure 2 , the shape of the light guide part 210 includes a water drop shape, a rectangular shape, etc.

[0053] For the convenience of the following description, it is defined that the side of the light guide plate 200 facing the circuit board 100 is a backlight surface, the side of the light guide plate 200 facing away from the circuit board 100 is a light exit surface, and the side of the light guide plate 200 connecting the backlight surface and the light exit surface.

[0054] It is worth mentioning that, in the embodiment of the present application, the light blocking part 220 can completely surround the side of the corresponding light guide part 210, so as to prevent the light between the adjacent light guide parts 210 from leaking and interfering. Of course, please refer to Figure 2, the light shielding part 220 can only partially surround the side of the light guide part 210, and the position of the corresponding gap is blocked by the side light source 110, at this time, the light shielding part 220 and the corresponding side light source 110 cooperate to completely surround the side of the light guide part 210. When the light shielding part 220 partially surrounds the side of the light guide part 210, the light shielding part 220 is provided with an anti-leakage finishing edge 221 at the position of the side light source 110, please refer to Figure 4 .

[0055] According to the embodiments of the present application, please refer to Figure 2 , the light guide part 210 includes a first light guide part 211, and the first light guide part 211 and the sensing button 120 are one-to-one correspondingly arranged, and the light guide part 210 further includes a second light guide part 212, one first light guide part 211 corresponds to at least two second light guide parts 212, and the second light guide part 212 is used to display the working mode adjusted by the sensing button 120 of the current first light guide part 211.

[0056] Combined with Figure 1 and Figure 2 , when the sensing button 120 is a capacitive touch button, a set of electrodes, usually two electrodes, are arranged on the PCB, one is a sensing electrode and the other is a ground electrode. An electric capacity is formed between the two electrodes, and the electric capacity is one-to-one correspondingly arranged with the first light guide part 211. When the finger touches the electric capacity between the two electrodes, the value of the electric capacity will change, thereby generating a capacitive change signal. The signal processing of the capacitive touch button is realized through a special capacitive touch chip. The chip converts the capacitive change signal into a digital signal, and performs filtering and de-bouncing processing, and finally outputs a stable switching signal. Through the signal processing of the capacitive touch button, the on-off of the side light source 110 corresponding to the first light guide part 211 and the on-off of the side light source 110 corresponding to the second light guide part 212 are controlled, thereby realizing the information interaction function of the display control assembly. When the sensing button 120 is a light sensing touch button, a resistance touch button, etc., it will also form a switching signal, and the on-off of the side light source 110 is controlled through the switching signal.

[0057] Among them, the side light source 110 on the circuit board 100 can be divided into two categories, the first category of side light source 111 is a function display light source corresponding to the sensing button 120 and the first light guide part 211, and the second category of side light source 112 is a mode display light source corresponding to the second light guide part 212. The first category of side light source 111 and the first light guide part 211 and the sensing button 120 are one-to-one correspondingly arranged, and the second category of side light source 112 and the second light guide part 212 are one-to-one correspondingly arranged. Each first category of side light source 111 corresponds to at least two second category of side light sources 112. Combined with Figure 5The display film 300 (to be described later) is taken as an example to illustrate the relationship between the function display light source and the mode display light source: for example, if the function display light source displays the refrigeration function, then the multiple mode display light sources corresponding to the function display light source can display the on / off or the size of the refrigeration function, etc. For another example, if the function display light source displays the ice making function, then the multiple mode display light sources corresponding to the function display light source can display the ice making stop, the ice making cleaning, the normal ice making, the fast ice making, etc. For another example, if the function display light source displays the quick fresh function, then the multiple mode display light sources corresponding to the function display light source can display the quick fresh off, the low temperature refrigerator, the fast micro-freezing, etc.

[0058] In one embodiment, when a certain sensing button 120 is pressed, the first type of side light source 111 corresponding to the sensing button 120 is turned on, and one of the second type of side light source 112 corresponding to the sensing button 120 is turned on. On this basis, the sensing button 120 is pressed again, and the second type of side light source 112 that is turned on is switched. The sensing button 120 is pressed for a long time, and the first type of side light source 111 and the second type of side light source 112 corresponding to the sensing button 120 are turned off.

[0059] In one embodiment, the first light guide part 211 is arranged in a column, part of the second light guide part 212 is arranged side by side with the first light guide part 211, and the rest of the second light guide part 212 is arranged between the adjacent first light guide parts 211. Of course, the division of the first light guide part 211 and the second light guide part 212 is not limited by the example here.

[0060] In one embodiment, the light guide portion 210 and the light blocking portion 220 are integrally injection molded. For example, the light guide plate 200 can adopt a two-color injection molding process to integrally injection mold the light guide portion 210 and the light blocking portion 220 on the light guide plate 200. The base material of the light guide plate 200 is a transparent plate material for optical display devices, which mainly serves to uniformly distribute the light emitted by the side light source 110 to the entire display unit cell, thereby achieving a display effect of uniform brightness and bright colors inside each light guide portion 210. The principle of the light guide plate 200 is to use the effects of total reflection and scattering to independently reflect and scatter the light emitted by the side light source 110 in each light guide portion 210, and finally uniformly diffuse out from the light guide portion 210. The light guide plate 200 is usually made of high-transparency organic glass or polycarbonate material, for example, the base material of the light guide plate 200 can but is not limited to high-transparency PMMA (polymethyl methacrylate) material. In addition, the light blocking portion 220 can but is not limited to black PS material (polystyrene) or black ABS material (black acrylonitrile-butadiene-styrene copolymer). By designing the light blocking portion 220, the light of the side light source 110 is surrounded on the corresponding light guide portion 210 that needs to display light, thereby achieving the function of independent light emission in multiple regions in a single plate surface with a simple structure.

[0061] Of course, the light guide plate 200 of the present application can be obtained by integrally injection molding the light guide portion 210 and the light blocking portion 220, or by encapsulating. The light blocking adhesive tape wraps the side surface of the light guide portion 210, so that the light between adjacent light guide portions 210 does not leak, and the light can only be emitted through the light emitting surface of the light guide portion 210.

[0062] According to the embodiments of the present application, in combination with Figure 6 The back surface of the light guide plate 200 is provided with a light reflecting layer 240, thereby preventing the light from being emitted from the back surface of the light guide plate 200. The reflecting layer 240 can be high-reflectivity paper, reflecting film, or high-reflectivity ink, etc. For example, the material of the reflecting layer 240 can be polyethylene terephthalate.

[0063] According to another embodiment of the present application, the back surface of the light guide plate 200 can also be specially designed, for example, the back surface of the light guide plate 200 is designed as a diamond-shaped reflecting surface, or a special pattern is provided on the back surface, such as laser dotting 250 or patterns, etc. The patterns are obtained by a pattern processing process, and the types of the pattern processing process can include: hot glue, hot skin, embossed pattern printing, color spraying, and stamp printing, etc.

[0064] Of course, the reflection layer 240 can also be arranged on the back of the light guide plate 200, and the back of the light guide plate 200 is specially designed at the same time, thereby increasing the scattering effect of the light and improving the brightness uniformity. For example, the light guide plate 200 in the present application is an acrylic or PC plate material (polycarbonate plate material) with laser dot 250 or rhombohedron pattern, fine grid pattern processing on the back, and PET reflective paper (polyethylene terephthalate) is arranged on the back of the light guide plate 200.

[0065] According to the embodiments of the present application, in combination with Figure 5 , the side of the light guide plate 200 facing away from the circuit board 100 (i.e. the light emitting surface) is provided with a display film 300, and the display film 300 is a black base film with a set light transmission area 310. The set light transmission area 310 forms at least one of the characters and patterns. The set light transmission area 310 of the display film 300 can display different characters, different patterns, different colors or a combination thereof as needed, to flexibly adapt to different display requirements. For example, the display film 300 makes the set light transmission area 310 into a semi-transparent white or semi-transparent color, which is used to display specific interactive information, and the non-displaying part is made into a black base color with light shielding material. The back of the display film 300 can be covered with glue for connecting with the light guide plate 200.

[0066] According to the embodiments of the present application, please refer to Figure 7 and Figure 8 , further comprising a mounting plate 400, the mounting plate 400 is formed with a receiving groove 410, and the circuit board 100 and the light guide plate 200 are fixed in the receiving groove 410. The mounting plate 400 can be but is not limited to a plastic part.

[0067] According to the embodiments of the present application, in combination with Figure 9 and Figure 10 , the mounting plate 400 is formed with at least one of an elastic buckle 420, a first mounting buckle 430, a second mounting buckle 440 and a wire slot buckle 450. Through the arrangement of the above buckles or the wire slot buckle 450, the difficulty and technical requirements of manual assembly can be greatly reduced.

[0068] The elastic buckle 420 is arranged on the side of the mounting plate 400 facing away from the circuit board 100, and is used for elastic deformation to be fixed in the mounting compartment, and the mounting compartment has a glass display window. For example, when the display control assembly is used for a refrigerator, the mounting compartment is formed in the refrigerator door panel, and then the display control assembly can be used for the interaction between the user and the refrigerator. The display control assembly can be inserted into the mounting compartment of the refrigerator door panel from the top of the door panel (arrow direction), and the elastic buckle 420 on the back of the mounting plate 400 provides the close contact force between the display control assembly and the mounting compartment, so that the display control assembly is stably fixed in the mounting compartment, and the light emitting surface of the light guide plate 200 faces the glass display window.

[0069] The first mounting buckle 430 is used to fix the circuit board 100 to prevent the circuit board 100 from falling off the mounting plate 400. The number of the first mounting buckle 430 is multiple and is distributed at intervals to ensure the reliability of the installation of the circuit board 100. For example Figure 7 and Figure 8 The first mounting buckle 430 is arranged on both sides of the accommodating groove 410 and is arranged in pairs. In addition, the mounting plate 400 can also be provided with a supporting rib for supporting the circuit board 100.

[0070] The second mounting buckle 440 is used to fix the light guide plate 200 to prevent the light guide plate 200 from falling off the mounting plate 400. The number of the second mounting buckle 440 is multiple and is distributed at intervals to ensure the reliability of the installation of the light guide plate 200. For example Figure 7 and Figure 8 The second mounting buckle 440 is arranged on both sides of the accommodating groove 410 and is arranged in pairs.

[0071] The wire slot buckle 450 is used to fix the wire on the mounting plate 400. The wire herein can be connected to the side light source 110 and other electrical elements on the circuit board 100. Figure 7 and Figure 9 The wire slot buckle 450 is arranged on one side of the mounting plate 400, and the position of the wire slot buckle 450 is staggered with the position of the accommodating groove 410, so as to prevent the wire in the wire slot buckle 450 from interfering with the installation of the circuit board 100 or the light guide plate 200.

[0072] According to the embodiments of the present application, a household appliance is also provided, which comprises the display control assembly. The household appliance herein can be a refrigerator, or an air conditioner, or a microwave oven, or other household appliances.
