[0030] In some cases, existing refrigerators have various functions such as preservation and defrosting, but users are not clear about the internal conditions of the refrigerator drawer, such as humidity, oxygen concentration, etc. It is difficult for users to intuitively observe the internal conditions of the refrigerator. For this reason, an explicit technology is needed to give users an intuitive experience.

[0031] Based on the above situation, the embodiment of the present application proposes a display panel and a refrigerator, aiming to enable a user to intuitively understand the internal conditions of the refrigerator.

[0032] Various embodiments of the display panel of the present application are further described below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, Figure 1 It is a schematic diagram of the structure of a display panel provided by an embodiment of the present application.

[0034] In one embodiment, the display panel 100 includes but is not limited to a first transparent substrate 111, a second transparent substrate 112 and a plurality of LED light sources 120. Specifically, the plurality of LED light sources 120 are located between the first transparent substrate 111 and the second transparent substrate 112, and the LED light source 120 is also connected to a conductive circuit 130, one end of the conductive circuit 130 is connected to the LED light source 120, and the other end is connected to a driving board.

[0035] Specifically, the driving board can drive the multiple LED light sources 120 to emit light, turn off, or change in a preset pattern; wherein the driving board can drive the multiple LED light sources 120 to emit light, thereby achieving a visual effect that can characterize the internal environmental state of the refrigerator. Since the display panel 100 of the embodiment of the present application can display the internal environmental state of the refrigerator by emitting light from the multiple LED light sources 120, the user can intuitively observe the internal situation of the refrigerator through the display panel 100, giving the user a more intuitive experience.

[0036] It should be noted that, regarding the installation position of the display panel 100, it can be installed inside the refrigerator, for example, the display panel 100 can be installed in the drawer inside the refrigerator, or it can be installed on at least one inner wall of the compartment of the refrigerator, or it can be installed on at least one inner wall of the door panel of the refrigerator, or it can be installed at other positions inside the refrigerator; in addition, the display panel 100 can also be installed outside the refrigerator, for example, the display panel 100 can be installed on at least one outer wall of the door panel of the refrigerator, or it can be installed at other positions outside the refrigerator.

[0037] For different installation positions of the display panel 100, the display scenes may be as follows:

[0038] Scenario 1: When the display panel 100 is installed inside the refrigerator, after opening the refrigerator door, the user can directly observe the pattern displayed by the LED light source 120 on the display panel 100 on the drawer, the inner wall of the compartment or the inner wall of the door panel, so that the user can directly know the internal conditions of the refrigerator, such as the internal environmental parameters of the refrigerator or the thawing status.

[0039] Scenario 2: When the display panel 100 is installed on the outside of the refrigerator, when the user approaches the refrigerator, he can directly observe the pattern displayed by the LED light source 120 on the display panel 100 on the outer wall of the door panel, so that the user can directly know the internal situation of the refrigerator, such as the internal environmental parameters of the refrigerator or the thawing status.

[0040] It should be noted that the above-mentioned refrigerator internal environment parameters may refer to temperature parameters, humidity parameters, oxygen concentration parameters, or other internal environment parameters, and the embodiments of the present application do not specifically limit this.

[0041] In addition, it should be noted that the above-mentioned thawing state may refer to the thawing process, the thawing time, the thawing temperature, or other thawing state parameters, and the embodiments of the present application do not specifically limit this.

[0042] In one embodiment, the first transparent substrate 111 and the second transparent substrate 112 need to be made of transparent materials to achieve a transparent effect, wherein the first transparent substrate 111 and the second transparent substrate 112 may be transparent glass products, which have the advantages of high transparency, chemical stability, heat resistance, corrosion resistance, etc.; or, the first transparent substrate 111 and the second transparent substrate 112 may also be transparent plastic products, such as polymethyl methacrylate, polycarbonate, etc., which have the advantages of lightness, easy processing, and low price; or, the first transparent substrate 111 and the second transparent substrate 112 may also be transparent ceramic products, such as aluminum oxide, zirconium oxide, etc., which have the characteristics of high hardness and high corrosion resistance; or, the first transparent substrate 111 and the second transparent substrate 112 may also be transparent crystal products, such as quartz crystal, calcium fluoride crystal, etc. In addition, the first transparent substrate 111 and the second transparent substrate 112 may also be made of other materials, which is not specifically limited in the embodiment of the present application.

[0043] In one embodiment, the above-mentioned LED light source 120 refers to a light emitting diode light source, which is a solid-state semiconductor device that can directly convert electrical energy into light energy and has the advantages of small size, long life, high efficiency, etc. The embodiment of the present application can use the LED light source 120 for parameter display, wherein the brightness of the LED light source 120 can be controlled by adjusting the current, so when it is necessary to display parameters of different levels, it can be achieved by adjusting the brightness of the LED.

[0044] Among them, the embodiment of the present application can add a light detection sensor for detecting the current ambient brightness to the refrigerator, so that the LED light source 120 can adjust its own brightness according to the ambient brightness information detected by the light detection sensor. For example, when the light detection sensor detects that the current environment is brighter, in order to enable the user to clearly see the pattern displayed by the LED light source 120, the embodiment of the present application can respond to increase the brightness of the LED light source 120; or, when the light detection sensor detects that the current environment is darker, in order not to cause a glare effect to the user, the embodiment of the present application can respond to reduce the brightness of the LED light source 120.

[0045] In one embodiment, in order to make the display panel 100 more transparent as a whole, the conductive circuit 130 can be a conductive wire made of a transparent material, which can meet the requirements of transmitting light and transmitting current. For example, the conductive circuit 130 can be made of transparent materials such as transparent plastic or glass fiber, which has good conductivity and can transmit light.

[0046] In one embodiment, the position of the driving board is arranged at the edge of the display panel 100, and then connected to the main control board of the refrigerator through a power supply cable and a communication cable. In addition, the driving board can also be arranged away from the display panel 100, and the embodiment of the present application does not specifically limit the installation position of the driving board.

[0047] In one embodiment, the display panel 100 of the embodiment of the present application can be set in the fresh-keeping drawer of a refrigerator, wherein the driving board can select and drive multiple LED light sources 120 to emit light, so that the multiple illuminated LED light sources 120 are combined to form display parameters with visual effects, and the internal environmental parameters of the fresh-keeping drawer are characterized by the display parameters.

[0048] Since the embodiment of the present application adds the above-mentioned display panel 100 to the fresh-keeping drawer, and the display panel 100 can display the internal environmental status of the fresh-keeping drawer by emitting light through multiple LED light sources 120, the user can intuitively observe the internal situation of the fresh-keeping drawer through the display panel 100, giving the user a more intuitive experience.

[0049] It should be noted that the embodiment of the present application can drive multiple LED light sources 120 to emit light, so that the multiple LED light sources 120 can be combined to emit light and display digital parameters, or display English parameters, or display digital parameters and English parameters at the same time, or display other characters, or display other graphics. The embodiment of the present application does not specifically limit the type of the above-mentioned display parameters.

[0050] In addition, it should be noted that the internal environmental parameters of the fresh-keeping drawer may refer to the temperature parameters of the fresh-keeping drawer, the humidity parameters of the fresh-keeping drawer, the oxygen concentration parameters of the fresh-keeping drawer, or other internal environmental parameters, and the embodiments of the present application do not specifically limit this.

[0051] In one embodiment, if Figure 2 As shown, Figure 2 This is a visual effect diagram of a display panel 100 provided in a fresh-keeping drawer provided by another embodiment of the present application. A plurality of LED light sources 120 are arranged to form one or more first arrangement combinations 210, wherein the LED light sources 120 in each first arrangement combination 210 are arranged in a plurality of 8-shaped shapes. The driving board can drive the LED light sources 120 in the first arrangement combination 210 to emit light and form digital parameters to form a visual effect for characterizing the internal environment parameters of the fresh-keeping drawer.

[0052] It should be noted that, for the multiple LED light sources 120 forming an 8-shape, the embodiment of the present application can select and drive part or all of the LED light sources 120 to emit light, thereby displaying the numbers "0", "1", "2", "3", "4", "5", "6", "7", "8" or "9", thereby representing the internal environmental parameters of the fresh-keeping drawer, such as temperature parameters, humidity parameters or oxygen concentration parameters, etc.

[0053] It can be understood that the 8-shape in each group of the first arrangement combination 210 can be a single 8-shape, two side-by-side 8-shapes, or a larger number of side-by-side 8-shapes, and the embodiment of the present application does not specifically limit this.

[0054] In one embodiment, if Figure 2 As shown, the first transparent substrate 111 or the second transparent substrate 112 may be provided with a pattern layer 220, which is located on the side of the LED light source 120 in the first arrangement combination 210. The pattern layer 220 cooperates with the LED light source 120 in the first arrangement combination 210 to characterize the internal environmental parameters of the fresh-keeping drawer.

[0055] The pattern layer 220 may display text or other character information, and the character information in the pattern layer 220 and the luminous LED light source 120 in the first arrangement and combination 210 may be combined to display and express the internal environment parameters of the fresh-keeping drawer. Figure 2 As shown, the pattern layer 220 can display the characters "oxygen concentration" and "%", and the user can know the numerical value of the oxygen concentration inside the fresh-keeping drawer through the pattern layer 220 and the digital parameters displayed by the LED light source 120 in the first arrangement combination 210 corresponding thereto; alternatively, the pattern layer 220 can display the characters "humidity" and "%", and the user can know the numerical value of the humidity inside the fresh-keeping drawer through the pattern layer 220 and the digital parameters displayed by the LED light source 120 in the first arrangement combination 210 corresponding thereto; alternatively, the pattern layer 220 can display the characters "temperature" and "℃", and the user can know the numerical value of the temperature inside the fresh-keeping drawer through the pattern layer 220 and the digital parameters displayed by the LED light source 120 in the first arrangement combination 210 corresponding thereto.

[0056] It is understandable that the pattern layer 220 can display Figure 2 In addition to the text shown, other text may also be displayed, and this embodiment of the present application does not specifically limit this.

[0057] In addition, it can be understood that the embodiment of the present application can be etched on the first transparent substrate 111 or the second transparent substrate 112 to form the above-mentioned pattern layer 220; or a sticker with character information can be directly pasted on the first transparent substrate 111 or the second transparent substrate 112 as the above-mentioned pattern layer 220.

[0058] In one embodiment, the display panel 100 of the embodiment of the present application can be set in the thawing drawer of the refrigerator, wherein the driving board can select and drive multiple LED light sources 120 to change in a preset style, so that the multiple LED light sources 120 are combined to emit light, and the visual effect formed by the combined lighting method of the multiple LED light sources 120 is used to represent the thawing process of the thawing drawer.

[0059] Since the embodiment of the present application adds the above-mentioned display panel 100 to the thawing drawer, and the display panel 100 can display the thawing process of the thawing drawer by emitting light through multiple LED light sources 120, the user can intuitively observe the thawing process of the thawing drawer through the display panel 100, giving the user a more intuitive experience.

[0060] It should be noted that the above-mentioned preset style changes can be a flowing style, that is, multiple LED light sources 120 emit light in sequence; it can also be a flashing style, that is, multiple LED light sources 120 flash continuously; it can also be other styles, and the embodiments of the present application do not make specific limitations on this.

[0061] For example, when the plurality of LED light sources 120 emit light in a flowing pattern or a flashing pattern, it may indicate that the food in the thawing drawer is in the thawing process; when the plurality of LED light sources 120 are off, it may indicate that the food in the thawing drawer has been thawed.

[0062] In addition, it should be noted that the thawing process of the thawing drawer may include but is not limited to the following stages:

[0063] Ice crystal formation stage: When frozen food begins to thaw, ice crystals begin to form. This is because during the freezing process, the water in the food gradually forms ice crystals. As the thawing progresses, the ice crystals gradually expand.

[0064] Melting stage: During this stage, the ice crystals gradually melt into liquid water. This process releases a lot of heat, so the temperature of the food will rise slightly.

[0065] Heat absorption stage: During the thawing process, the food absorbs heat, causing its temperature to rise. This process can promote the melting of ice crystals, allowing more water to change from solid ice crystals to liquid water.

[0066] Temperature Rising Phase: As the defrosting process progresses, the temperature of the food will gradually rise. This process may take some time, depending on the size and type of food.

[0067] Completely thawed stage: When all the ice crystals in the food have melted into liquid water, the food is completely thawed. At this point, the temperature of the food has reached room temperature or a temperature close to room temperature.

[0068] It should be noted that the embodiments of the present application may use different preset styles to represent different thawing stages, or different display effects under the same preset style may be used to represent different thawing stages. For example, when multiple LED light sources 120 emit light at a high-frequency speed in a flowing water style, it can represent that the thawing stage in the thawing drawer is currently in the ice crystal formation stage; when multiple LED light sources 120 emit light at a medium-high frequency speed in a flowing water style, it can represent that the thawing stage in the thawing drawer is currently in the melting stage; when multiple LED light sources 120 emit light at a medium-frequency speed in a flowing water style, it can represent that the thawing stage in the thawing drawer is currently in the heat absorption stage; when multiple LED light sources 120 emit light at a medium-low frequency speed in a flowing water style, it can represent that the thawing stage in the thawing drawer is currently in the temperature rising stage; when multiple LED light sources 120 emit light at a low-frequency speed in a flowing water style, it can represent that the thawing stage in the thawing drawer is currently in the complete thawing stage.

[0069] In one embodiment, if Figure 3 As shown, Figure 3 This is a visual effect diagram of a display panel 100 provided in a defrosting drawer provided by another embodiment of the present application. A plurality of LED light sources 120 are arranged to form at least one second arrangement combination 300, and a plurality of LED light sources 120 in each second arrangement combination 300 are arranged horizontally or vertically; wherein the driving board is used to drive the LED light sources 120 in the second arrangement combination 300 to emit light in sequence, so as to form a running light visual effect for representing the defrosting process of the defrosting drawer. Figure 3 The LED light sources 120 with solid shadows in the figure are emitting LED light sources 120 , and the LED light sources 120 with hollow shadows are extinguished LED light sources 120 .

[0070] In one embodiment, the embodiment of the present application can also control the light color of the LED light source 120 in the second arrangement combination 300 through the driving board, so as to characterize the thawing temperature of the thawing drawer through the light color. For example, if the light color of the LED light source 120 in the second arrangement combination 300 is blue, it can be characterized that the thawing temperature of the thawing drawer is low; if the light color of the LED light source 120 in the second arrangement combination 300 is red, it can be characterized that the thawing temperature of the thawing drawer is high.

[0071] In one embodiment, if Figure 1 As shown, the display panel 100 of the embodiment of the present application further includes but is not limited to a light-transmitting film 140 . The light-transmitting film 140 is disposed between the first transparent substrate 111 and the second transparent substrate 112 , and the LED light sources 120 are distributed on the light-transmitting film 140 .

[0072] The embodiment of the present application can adopt a solution in which a light-transmitting film 140 carries the LED light source 120, which can reduce the thickness of the display panel 100. The light-transmitting film 140 can be a flexible transparent material. The light-transmitting film 140 serves as a carrying layer to form a conductive circuit 130 on the first surface. For example, the conductive circuit 130 is etched on the coated light-transmitting film 140 by laser etching or the like, and then the LED light source 120 is connected to the flexible transparent film on which the conductive circuit 130 has been etched through an ITO (indium tin oxide, Indium-Tin-Oxide) conductive electrode or conductive ink to form an LED flexible display film. The LED flexible display film is connected to the driving board to form the display panel 100 of the present application.

[0073] In one embodiment, the light-transmitting film 140 is a PVB film or an EVA film. PVB film is also called polyvinyl butyral film, which is a thermoplastic resin film, and is essentially produced by adding a plasticizer to PVB resin. EVA film is also called ethylene-vinyl acetate copolymer film, which is a thermoplastic elastomer material and is widely used in various fields.
