The components of one embodiment of the display assembly of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 1, thedisplay assembly 10 may be used on a household appliance. In the present embodiment, thedisplay module 10 includes adisplay panel 11, adisplay film 12, alight blocking member 13, acircuit board 14, and acircuit board shutter 15. Thedisplay panel 11 is exposed to form a part of the appearance surface of the household appliance and is used for displaying an operation display interface of the household appliance. Thedisplay film 12, thelight blocking member 13, thecircuit board 14, and thecircuit board barrier 15 are sequentially stacked inside thedisplay panel 11. Thecircuit board 14 is provided with alight emitting member 141, and light emitted from thelight emitting member 141 passes through thelight blocking member 13 and irradiates thedisplay film 12, so as to display an operation display interface of the household appliance on thedisplay panel 11.

In some embodiments, thedisplay panel 11 is made of transparent or translucent ABS plastic, PC plastic, PVC plastic, or PET plastic with color masterbatch, so that the light emitted from the light-emittingmember 141 on thecircuit board 14 can be transmitted, thereby forming a clear color mark on thedisplay panel 11. In other embodiments, thedisplay panel 11 may also be made of glass. In some embodiments, thedisplay panel 11 is planar. Theplanar display panel 11 facilitates assembly of thedisplay film 12 and thecircuit board 14 located therein, and the display effect of the color mark on thedisplay panel 11 is smooth, and the display defects such as light leakage and crosstalk are not easy to occur. In other embodiments, thedisplay panel 11 may also be a curved surface to meet the requirements of some curved surface shapes of the household appliances.

Referring to fig. 1, in the present embodiment, thedisplay film 12 is mounted on the inner side of thedisplay panel 11. The mode of assembling thedisplay film 12 on the inner side of thedisplay panel 11 is adopted, so that the assembly is convenient, and the replacement of the damageddisplay film 12 is convenient. Thedisplay film 12 can be fixed on the inner side surface of thedisplay panel 11 by means of pasting, clamping and the like. In some embodiments, thedisplay film 12 is integrally injection molded with thedisplay panel 11. For example, thedisplay film 12 is injection-molded integrally with thedisplay panel 11 by In-mold decoration (IMD). By integrally molding thedisplay film 12 on thedisplay panel 11, the number of parts to be assembled can be reduced, thereby simplifying the assembly process. In other embodiments, thedisplay film 12 may be assembled with thedisplay panel 11 after being injection molded with another injection molded part by in-mold decoration. In other embodiments, thedisplay film 12 is exposed and used directly as thedisplay panel 11. By directly using thedisplay film 12 as thedisplay panel 11, the number of parts can be reduced. For thedisplay film 12 used directly as thedisplay panel 11, the thickness thereof is set to not less than 0.3mm in order to secure the strength thereof; to facilitate the assembly of thedisplay film 12, a holding structure may be disposed on thedisplay film 12 to connect thedisplay film 12 with other components. In some embodiments, thedisplay film 12 may also be fixed to thelight barrier 13 by means of bonding, clipping, or integral injection molding.

Referring to fig. 1, thelight blocking member 13 is disposed between thecircuit board 14 and thedisplay film 12, and thelight blocking member 13 is provided with alight exit hole 131 corresponding to thecolor icon 121. Thelight blocking member 13 can perform the functions of condensing light and reducing light leakage, so that the light emitted from thelight emitting member 141 on thecircuit board 14 can be more intensively irradiated on thecolor icons 121 on thedisplay film 12, thereby improving the display effect when thecolor icons 121 are projected on thedisplay panel 11. In some embodiments, thelight blocking member 13 is a plastic member, and thelight exit hole 131 is defined by a rib. As shown in fig. 1, the shape of thelight exit hole 131 may be various, so that the area illuminated by thelight emitting member 141 through thelight exit hole 131 is different in shape. In this embodiment, the light-emittinghole 131 includes that it establishes the circular port to enclose by circular fender muscle to and enclose the "protruding" word shape hole of establishing and forming by "protruding" word fender muscle. When thecircuit board 14 and thelight blocking member 13 are relatively fixed, thelight emitting member 141 on thecircuit board 14 is correspondingly located in thelight emitting hole 131.

The illuminatingmember 141 on thecircuit board 14 is used for illuminating thecolor icon 121. Thecircuit board 14 is provided with alight emitting controller 142 electrically connected to thelight emitting member 141. Referring to fig. 2, thelight emitting element 141 on thecircuit board 14 is disposed on a surface of thecircuit board 14 facing thedisplay panel 11. The position distribution of thelight emitting elements 141 on thecircuit board 14 corresponds to the position distribution of thecolor icons 121 on thedisplay film 12. Thelight emitting member 141 includes a first light emitting state and a second light emitting state, and thelight emitting member 141 is controlled by thelight emitting controller 142 to be in the first light emitting state or the second light emitting state. Thelight emitting member 141 emits light of a first color in the first light emitting state, and emits light of a second color different from the first color in the second light emitting state. Thelight emitting member 141 can emit light of different colors to irradiate on thecolor icon 121 of thedisplay film 12, so that thecolor icon 121 can present a changed color, and the color is rich, and a user can visually know the working state of the household appliance to which thedisplay assembly 10 is applied according to the color change of thecolor icon 121.

In some embodiments, thelighting member 141 includes a plurality of color-changing backlights capable of changing lighting colors. Each of the color changing backlights emits light of a first color in a first lighting state and emits light of a second color different from the first color in a second lighting state. Each of the variable color backlight lamps can emit light of at least two colors, so that the number of the backlight lamps does not need to be increased while the types of the light emitting colors are increased, and the arrangement of the backlight lamps on thecircuit board 14 is convenient. The color-changing backlight generally has a plurality of light emitting chips therein, and the light emitted from different light emitting chips has different colors, and the light of different colors can be mixed to form more colors. For example, a color-changing backlight lamp is internally provided with a red light chip, a green light chip and a blue light chip, and red, green and blue light emitted by the red light chip, the green light chip and the blue light chip are mixed according to different proportions to present a colorful color. In other embodiments, the illuminatingmember 141 comprises a plurality of monochrome backlights, at least two of the monochrome backlights have different illumination colors, and at least two of the monochrome backlights having different illumination colors are used to illuminate thesame color icon 121. The monochrome backlights with different light emitting colors are adopted, and the color change is realized by controlling the on-off of the monochrome backlights with different light emitting colors, so that the control is simple. For example, two monochromatic backlights are located close to each other, one of which is a backlight emitting red light and the other is a backlight emitting blue light. When the light-emittingcontroller 142 controls the red backlight to be turned on and the blue backlight to be turned off, thecorresponding color icon 121 is illuminated by the red light to be red, and at this time, the color icon is in a first light-emitting state of the light-emittingmember 141; when the light-emittingcontroller 142 controls the blue backlight to be turned on and the red backlight to be turned off, thecorresponding color icon 121 is illuminated by the blue light to appear blue, and the light-emittingelement 141 is in the second light-emitting state. In this embodiment, the color-changing backlight and the monochromatic backlight may be LED chip lamp beads or LED in-line lamp beads. The illuminatingmember 141 further includes anixie tube 144, and thenixie tube 144 is used for displaying time, temperature and other numerical values.

Thelight emission controller 142 is disposed on a side of thecircuit board 14 facing away from thedisplay panel 11. The arrangement can prevent thelight controller 142 from shielding the light emitted by thelight emitting member 141 to affect the display effect, and can also prevent thecircuit board 14 from interfering with thelight blocking member 13 when thecircuit board 14 is installed with thelight emitting member 141 at a short distance. Thelight controller 142 may include a single chip, a color mixing controller, and other microprocessors, etc. Thecircuit board 14 is further provided with atouch key 143, thetouch key 143 is a spring key, and a light-emittingmember 141 is also arranged in the spring key to illuminate to display a color mark capable of being input by touch.

In this embodiment, thecircuit board 14 is a display circuit board mainly used for display and touch input, and thelight emitting element 141 and thelight emitting controller 142 are both disposed on thecircuit board 14. In other embodiments, thelight controller 142 may not be disposed on thesame circuit board 14 as thelight emitting element 141. For example, thelight emitting controller 142 is disposed on another main control board independent from thecircuit board 14, and the main control board is connected to thecircuit board 14 by a wire or by wireless transmission, so as to electrically connect thelight emitting controller 142 and thelight emitting element 141. For another example, thelight emitting controller 142 is a separately disposed control module, which is electrically connected to thecircuit board 14 by a wire or wireless transmission, so as to control thelight emitting element 141 on thecircuit board 14. The wireless transmission mode may be, for example, wireless transmission technologies such as WIFI, bluetooth, infrared, and NFC. In other embodiments, the display assembly may not include thecircuit board 14. For example, thelight emitting member 141 is a light strip controlled by thelight emitting controller 142. Similar to the above, thelight emitting controller 142 may be disposed on another circuit board, or may be a separately disposed control module; thelighting controller 142 may control the lighting and extinguishing of the light strip and the change of the color in a wired or wireless manner.

Referring to fig. 3, thedisplay assembly 10 further includes a cuptype identification circuit 145, atiming circuit 146, atemperature detection circuit 147, and a motor operatingstate detection circuit 148. Specifically, in this embodiment, thecircuit board 14 is provided with a cuptype identification circuit 145, atiming circuit 146, atemperature detection circuit 147, and a motor workingstate detection circuit 148, and thelight emitting controller 142 is connected to the cuptype identification circuit 145, thetiming circuit 146, thetemperature detection circuit 147, and the motor workingstate detection circuit 148, so that the light emitting color of thelight emitting element 141 can be controlled according to the detected cup type, time, temperature, and motor working state, and thus, a user can know the current cup type, time, temperature, and motor working state of the household appliance in time. In other embodiments, according to actual needs, one or more of the cuptype identification circuit 145, thetiming circuit 146, thetemperature detection circuit 147, and the motor operatingstate detection circuit 148 may be disposed on thecircuit board 14, and thelight emitting controller 142 is connected to one or more of the cup type identification circuit, thetiming circuit 146, thetemperature detection circuit 147, and the motor operatingstate detection circuit 148 to identify the state thereof and control the light emitting color of thelight emitting element 141.

In other embodiments, one or more of the cuptype identification circuit 145, thetimer circuit 146, thetemperature detection circuit 147, and the motor operatingcondition detection circuit 148 may be disposed on a circuit board different from thecircuit board 14. For example, thecircuit board 14 is a display circuit board mainly used for display and touch input in a household appliance, the household appliance also includes a power board mainly used for converting commercial power into voltage for components inside the household appliance, and one or more of the cup bodytype identification circuit 145, thetiming circuit 146, thetemperature detection circuit 147 and the motor workingstate detection circuit 148 may be disposed on the power board. In other embodiments, the household appliance may further include a plurality of circuit boards, for example, thetemperature detection circuit 147 may be disposed on a separate temperature detection circuit board, thetiming circuit 146 may be disposed on a separate timing circuit board, and the like.

The bottom of thehot beverage cup 200 is provided with a heating plate. When a user needs to make a hot beverage, such as making delicious thick soybean milk, the user selects thehot beverage cup 200 to place on themain machine 100, and presses a function button for making the delicious thick soybean milk on thedisplay assembly 10, so that the processor executes the procedures of crushing, boiling and the like to make delicious thick soybean milk. When a user needs to make a cold drink, for example, ice-added apple juice, the user selects the colddrink cooking cup 300 to be placed on thehost computer 100, and presses a function key for making the ice-added apple juice on thedisplay assembly 10, the cooking machine executes a corresponding program to make the cool ice-added apple juice. In other embodiments, the household appliance may also be a blender, an electric rice cooker, a pressure cooker, an electric kettle, a coffee maker, a frying and baking machine, a microwave oven, or the like.

The lighting control effect of thelighting element 141 will be described in detail with reference to the householdelectrical appliance 500 shown in fig. 4 and the block diagram of the circuit module shown in fig. 3.

For example, when the user places thehot beverage cup 200 on themain body 100 and selects a function, the cuptype identification circuit 145 detects that the cup is thehot beverage cup 200, and thelight controller 142 controls thelight emitting member 141 to emit orange light according to the signal, and the orange light illuminates thecolor icon 121 on thedisplay film 12 to present an orange pattern on thedisplay panel 11. Orange may remind the user that hotdrink preparation cup 200 is currently in use, reminding the user to pay attention to scalding. When the user selects a functional program to be executed and finished, for example, 10-30 seconds before the program is finished, the light-emittingcontroller 142 controls the light-emittingmember 141 to emit red light according to the timing signal of thetiming circuit 146, and the red light illuminates thecolor icon 121 on thedisplay film 12 to present a red pattern on thedisplay panel 11, which may remind the user that the program is finished.

For another example, when the user places the colddrink processing cup 300 on themain body 100 and selects the function, the cuptype identification circuit 145 detects that the processing cup is the colddrink processing cup 300, and thelight controller 142 controls thelight emitting member 141 to emit blue light according to the signal, and the blue light illuminates thecolor icon 121 on thedisplay film 12 to present a blue pattern on thedisplay panel 11. The blue color may remind the user that colddrink cooking cup 300 is currently in use. After the user selects the function, the blade in thecold drink cup 300 is driven by the motor to rotate at a high speed, at this time, the light-emittingcontroller 142 detects that the motor is in the working state according to the motor workingstate detection circuit 148, the light-emittingmember 141 is controlled to emit purple light, and the purple light irradiates thecolor icon 121 on thedisplay film 12 to present a purple pattern on thedisplay panel 11, so as to remind the user of paying attention to the rotating blade and prevent nicking. When the user selects a functional program to be executed and finished, for example, 10-30 seconds before the program is finished, the light-emittingcontroller 142 controls the light-emittingmember 141 to emit red light according to the timing signal of thetiming circuit 146, and the red light illuminates thecolor icon 121 on thedisplay film 12 to present a red pattern on thedisplay panel 11, which may remind the user that the program is finished.

For another example, after the user places thehot drink cup 200 on thehost 100 and selects the function, the cuptype recognition circuit 145 detects that the cup is thehot drink cup 200, thelight emitting controller 142 controls thelight emitting member 141 to emit orange light according to the signal, when the temperature of the food in the cup rises to 60 degrees centigrade, thelight emitting controller 142 controls thelight emitting member 141 to emit pink light according to the temperature value signal detected by thetemperature detection circuit 147, when the temperature of the food in the cup rises to 90 degrees centigrade, thelight emitting controller 142 controls thelight emitting member 141 to emit red light according to the temperature value signal detected by thetemperature detection circuit 147, so as to remind the user of temperature change, and prevent scald. The light of different colors lights up thecolor icon 121 on thedisplay film 12 to present different colors on thedisplay panel 11, so that the user can know the operation condition of the food processor more intuitively, and the technological sense and the use safety are enhanced.

In addition, since thecolor icon 121 may include a plurality of regions, different regions may have different colors when illuminated with light of the same color, so that color display may be achieved. Therefore, the color of the light emitted from thelight emitting member 141 does not coincide with the color of the pattern formed on thedisplay panel 11 after thecolor icon 121 on thedisplay film 12 is irradiated. It will be appreciated that light of a different colour is shone on thecoloured icons 121, the colour of the pattern which it presents on thedisplay panel 11 being varied.

The colored icon A, B, C, D can be printed directly on the surface of thesubstrate 101 or on another layer on thesubstrate 101, i.e., there can be another layer between the colored icon A, B, C, D and thesubstrate 101.

Color icon layer 103 includes one or more color icons A, B, C, D. The at least one colored icon A, B, C, D includes multiple regions, at least two different regions displaying different colors. In some embodiments, the different colors may include different colors mixed by three primary colors of different proportions.

Fig. 6 is a black and white schematic diagram showing an example of a color icon. The color icon includes a plurality of regions, such asregion 106 and 109, which are indicated in FIG. 6. Thearea 106 in the color icon representing the juice in the cup may be orange in color, thearea 107 in the color icon representing the orange may be orange in color, thearea 108 representing the strawberry may be red in color, and thearea 109 representing the leaves may be green in color. Thedifferent areas 106 and 109 of the color icon can be different colors, so that the color icon presents multiple colors and the icon is rich in image. The different regions 106-109 are formed by color blocks of different colors. Referring to fig. 6 (1) and (2), in some embodiments, at least one color patch appears on the display panel under illumination by light of a first color and does not appear on the display panel under illumination by light of a second color. For example, the 106 regions marked in fig. 6, which are shown as orange under red light illumination, are shaped as shown in fig. 6 (1); but not under blue light irradiation, the shape is as shown in fig. 6 (2). For example, this can indicate a state in which liquid is present or absent in the cooking cup. Different patterns are shown by the colored icons under the irradiation of different colored lights, so that the working state information can be more abundantly shown, and the technological sense is increased. The color blocks may be formed by printing color inks on thesubstrate 101. The color ink is used for printing and forming, the process is simple, and the color blocks are not easy to distort. For illustration purposes only, only a part of thearea 106 and 109 are labeled in fig. 6, and the color icon of fig. 6 further includes other non-labeled areas, and the color of each area may be a color close to the real object. Fig. 6 is only an example, and the actual application is not limited to this example, and the icon and its color may be designed according to the actual application.

With continued reference to fig. 5, in some embodiments, a colored icon A, B, C, D may represent a function or the like. For example, the colored icons in fig. 6 may represent functions for making juice. Different colored icons A, B, C, D may indicate different functions, such as soymilk making, corn juice making, rice paste making, milkshakes making, and the like. The colored icon A, B, C, D may be in physical proximity. The colored icon A, B, C, D may include a logo, pattern, text, and/or letters, etc.

In some embodiments, at least two regions (e.g.,region 106 and 109 in fig. 6) of the colored icon A, B, C, D are different colors under the illumination of the same color of light and are translucent, allowing the light to pass through, and the colored icon A, B, C, D under the illumination of the light can be more aesthetically pleasing. In some embodiments, thecolor icon layer 103 is translucent, and areas of the color icon A, B, C, D are translucent, and are more clearly visible under lighting, and the color icon A, B, C, D can be more aesthetically pleasing. In other embodiments, colored icon A, B, C, D is opaque.

In some embodiments, thecolor icon layer 103 may be formed on thesubstrate 101 by four color printing, and the color icon A, B, C, D may be formed on thesubstrate 101 by four color printing, and may be printed with a rich color icon. The four-color printing refers to printing with three primary colors (yellow, magenta, cyan) and black by subtractive color method. In the example shown in fig. 5, in fig. 1, a color icon A, B, C, D is formed on one side of thebase material 101 by four-color printing.

In other embodiments, thecolor icon layer 103 may be sprayed on thesubstrate 101, or adhered to thesubstrate 101 using a film or sheet material.

In some embodiments, the colored icon A, B, C, D comprises a visible colored icon formed on thefirst side 1011 of thesubstrate 101, the visible colored icon appearing on the second side of thesubstrate 101 in the absence of illumination by the light. In one embodiment, the visible color icon may be printed directly on thefirst side 1011 of the fullytransparent substrate 101. In use, the second side of thesubstrate 101 faces the user, who views the colored icon A, B, C, D from the second side. A light emitter may be positioned behind thefirst side 1011 of thesubstrate 101 and may emit a light that illuminates a visible color icon from thefirst side 1011 of thesubstrate 101. When the light emitting element is not emitting light, a visible colored icon is visible from the second side of thesubstrate 101, but the icon is not illuminated; when the luminous element emits light, the light can penetrate through the visible color icon, and the visible color icon is lightened. In the embodiment shown in fig. 5, colored icons A, B, C, D are all visible colored icons. The visible color icons can be seen without lighting the illuminating piece, and are visual and vivid, so that the user can conveniently check and operate the visible color icons, and the electric quantity is saved.
