[0021] Currently, in home appliances such as water purifiers, the display panel is a key component for enabling human-computer interaction. Related technologies involve developing the display panel for each appliance from scratch, encompassing the entire development process, including the main control chip, peripheral circuits, PCB layout, and software driver adaptation. However, this development model results in a significant amount of repetitive work, leading to long development cycles, low efficiency, and the creation of numerous display panel versions, resulting in high production costs.

[0022] This application provides a display panel and a household appliance, which helps to improve the versatility of the display panel, shorten the development time of the display panel, and reduce the production and maintenance costs of the display panel.

[0023] Firstly, this application provides a display panel.

[0024] Combination Figures 1 to 3 As shown, the display board provided in this application includes a base plate 100 and a core plate 200.

[0028] With the above technical solution adopted, the display board of this application includes two main modules: a base plate 100 and a core plate 200. The core plate 200 integrates the main functions such as the control chip and can be directly applied to different household appliances without any modification to the core plate 200. To meet the differentiated needs of different household appliances, only simple base plate development is required, adjusting the display module 101 of the base plate 100 and reserving a mounting area for the core plate 200 on the base plate 100. After the base plate development is completed, the core plate 200 is fixed on the mounting area, and communication between the base plate 100 and the core plate 200 is achieved through an electrical connection between the second connecting component of the core plate 200 and the first connecting component on the base plate 100. This configuration results in high versatility of the display board, which helps to shorten the development time of the display board. Simultaneously, the core plate 200 can be mass-produced, which helps to reduce production and maintenance costs.

[0029] In some embodiments, the control chip includes a main control chip 202 and a functional chip 203 communicatively connected to the main control chip 202. The functional chip 203 includes one or more of a WiFi chip, a voice chip, and a storage chip. The main control chip 202 plays a primary control role, while the functional chip 203 enables functions such as wireless communication, voice control, and storage.

[0030] WiFi chips enable wireless network connectivity, allowing home appliances to access the internet and be remotely controlled; voice chips enable voice control, allowing home appliances to understand and execute voice commands; and storage chips are responsible for storing data such as device programs, user settings, and voice files, ensuring the normal operation of the device.

[0031] In the exemplary embodiments, the types and number of chips included in the functional chip 203 are not unique, and those skilled in the art can select them as needed. For example, the functional chip 203 may only include a memory chip, or the functional chip 203 may include a memory chip and a WiFi chip, or the functional chip 203 may include a WiFi chip, a voice chip, and a memory chip, or those skilled in the art may add other types of chips as needed.

[0032] In some embodiments, an interaction module 102 is further provided on the first side of the base plate 100, and the first connecting component is electrically connected to the interaction module 102. Interaction with the user can be realized through the interaction module 102.

[0033] In some embodiments, the interaction module 102 includes one or more of indicator lights, buttons, knobs, and buzzers. Interaction with the user can be achieved through indicator lights, buttons, knobs, and buzzers. The following explanation uses a display panel applied to a water purifier as an example: the user can determine the various operating states of the water purifier through the color and flashing pattern of the indicator lights; the user can turn the machine on and off, switch the operating mode of the water purifier, or adjust the water temperature using buttons and knobs; and the user can receive audible prompts through the buzzer.

[0034] In the exemplary embodiments, the types and number of interactive elements included in the interaction module 102 are not unique, and those skilled in the art can select them as needed. For example, the interaction module 102 includes indicator lights and buttons, or the interaction module 102 includes indicator lights, knobs and buzzers, or those skilled in the art can add other types of interactive elements as needed.

[0035] Optionally, the main control chip 202 is provided with pins, and the second connection component is electrically connected to the main control chip 202 through the pins. Pins, also known as traces, are wiring leads from the internal circuitry of the chip to the external circuitry.

[0036] Optionally, both the base plate 100 and the substrate 201 are PCB boards.

[0037] In some embodiments, combined with Figure 1 and Figure 2As shown, the second connection component includes stamp holes 204 disposed around the periphery of the substrate 201, and the stamp holes 204 are electrically connected to the main control chip 202. The first connection component includes solder joints disposed around the periphery of the mounting area, and the solder joints are electrically connected to the interaction module 102. The stamp holes 204 are used for soldering connections with the solder joints. By providing stamp holes 204 and soldering connections with them, not only can the core board 200 be fixed on the mounting area, but also the electrical connection between the stamp holes 204 and the solder joints can be achieved, thereby enabling communication between the main control chip 202 and the interaction module 102. In addition, the stamp holes 204 are connected by soldering, resulting in a stable connection and a very short transmission path, which is beneficial for improving communication quality.

[0038] Optionally, the stamp hole 204 is electrically connected to the main control chip 202 via copper wires on the substrate 201. The solder joints are electrically connected to the interaction module 102 via copper wires on the base plate 100.

[0039] In the exemplary embodiments, the stamp hole 204 and solder joints are not essential in this application, and those skilled in the art can adjust them according to actual needs. For example, board-to-board connectors can be used to replace the stamp hole 204 and solder joints. The two connectors are respectively soldered to the base plate 100 and the substrate 201, and are electrically connected to the main control chip 202 and the interaction module 102 respectively. The two connectors can be directly plugged into each other to realize communication between the main control chip 202 and the interaction module 102; or, spring pins can be used to replace the stamp hole 204 and solder joints. A row of spring pins is installed on the base plate 100, and the spring pins are electrically connected to the interaction module 102. The core board 200 is provided with a connection to the main control chip 202. 2. The contact points are aligned with the spring pins and pressed down. The spring pressure maintains the contact between the core board 200 and the spring pins, enabling communication between the main control chip 202 and the interaction module 102. Alternatively, terminal connections can be used instead of stamp holes 204 and solder points. A terminal interface electrically connected to the main control chip 202 is set on the base plate 100, and a terminal connected to the interaction module 102 is set on the substrate 201. By inserting the terminal into the terminal interface, communication between the main control chip 202 and the interaction module 102 can be achieved.

[0040] In some embodiments, combined with Figure 1 As shown, the second connection component also includes a terminal interface 205 disposed on the substrate 201, which is electrically connected to the main control chip 202. The first connection component also includes a connection terminal electrically connected to the display module 101 via a connection cable. The connection terminal is adapted to be inserted into the terminal interface 205 to realize communication between the display module 101 and the main control chip 202. By setting the terminal interface 205, when assembling the base plate 100 and the core board 200, it is only necessary to insert the connection terminal into the terminal interface 205 to realize communication between the main control chip 202 and the display module 101, making installation convenient.

[0041] Optionally, the terminal interface 205 is electrically connected to the main control chip 202 via copper wires on the substrate 201. The connection terminal is electrically connected to the display module 101 via wires.

[0042] In the exemplary embodiments, the terminal interface 205 and the connection terminal in this application are not mandatory, and those skilled in the art can adjust them according to actual needs. For example, soldering points electrically connected to the main control chip 202 can be provided on the substrate 201, and connecting lines electrically connected to the display module 101 can be provided on the base plate 100. By soldering the connecting lines to the soldering points, communication between the main control chip 202 and the display module 101 can also be realized.

[0043] In some embodiments, the core board 200 further includes a signal shielding box 206 disposed on the substrate 201, and the main control chip 202 is disposed within the signal shielding box 206. By providing the signal shielding box 206, external signals can be shielded, preventing interference to the main control chip 202 within the signal shielding box 206.

[0044] Optionally, the signal shielding box 206 is an iron box.

[0045] In some embodiments, combined with Figure 2 As shown, a bracket 103 is also provided on the first side of the base plate 100, and the display module 101 is fixed on the bracket 103. By providing the bracket 103, it is easy to fix the display module 101.

[0046] Optionally, the bracket 103 is provided with a clearance hole, through which the interaction module 102 passes and connects to the base plate 100.

[0047] Optionally, the display module 101 is attached to the bracket 103. For example, the display module 101 is provided with adhesive backing, which allows the display module 101 to be attached to the bracket 103.

[0048] In some embodiments, the bracket 103 is provided with a heat-fusion column, and the base plate 100 has a fixing hole for inserting the heat-fusion column. The heat-fusion column can be filled into the fixing hole after being heat-fused. After the heat-fusion column passes through the fixing hole on the base plate 100, it is melted by the heat-fusion process. The molten plastic fills the fixing hole and, after cooling, forms a shape similar to a rivet or a mushroom head, thereby tightly locking the bracket 103 and the base plate 100 together.

[0049] In some embodiments, the display module 101 is a TF display screen. A TF display screen refers to a liquid crystal display screen using TFT (Thin-Film Transistor) technology, which has advantages such as fast response speed, high contrast, and vibrant colors. By applying TF displays to home appliances, information can be displayed graphically, such as the operating status of the home appliance, setting parameters, graphs, recipes, weather, etc., while also supporting rich UI animations and icons, which helps to improve the user experience.

[0050] In the exemplary embodiments, the type of display screen used in the display module 101 is not unique, and those skilled in the art can select it as needed. For example, the display module 101 may also use an OLED display screen, an e-ink screen, or a TN-LCD display screen, etc.

[0051] In some embodiments, combined with Figure 1 As shown, the base plate 100 is also provided with a positioning groove 104, which allows a positioning block on the mounting base to engage when the display panel is installed on the mounting substrate. The display panel is installed on the mounting substrate, which can be a partial structure of a household appliance. By providing the positioning groove 104 on the base plate 100 of the display panel, the positioning block on the mounting substrate and the positioning groove 104 on the base plate 100 are aligned, thus determining the installation position of the display panel, preventing mistaken identification and avoiding positioning and installation errors.

[0052] In the exemplary embodiment, the structure of the positioning groove 104 is not fixed and can be adjusted as needed by those skilled in the art. For example, the positioning groove 104 can be circular, square, or triangular.

[0053] In the exemplary embodiments, the number of positioning slots 104 is not fixed and can be adjusted by those skilled in the art according to actual needs. For example, the number of positioning slots 104 may be 1, 2, 3, 4 or 5, etc. The number of positioning slots 104 is the same as the number of positioning blocks, and their positions and shapes correspond.

[0054] In some embodiments, combined with Figure 2 As shown, the base plate 100 is also provided with bolt holes 105. When the display panel is mounted on the mounting base, the bolt holes 105 are used for bolts to be inserted to fix the base plate 100 to the mounting base. The display panel is mounted on the mounting base, which can be a partial structure of a household appliance. The mounting base is provided with fixing holes. By aligning the fixing holes on the mounting base and the bolt holes 105 on the base plate 100 of the display panel with the bolt holes 105 on the base plate 100, and tightening the bolts, the base plate 100 and the mounting base can be fixedly connected.

[0055] In the exemplary embodiment, the fixing structure between the base plate 100 and the mounting base is not fixed, and those skilled in the art can adjust it as needed. For example, the fixing between the base plate and the mounting base can be achieved by means of adhesive or clips.

[0056] Optionally, the number of bolt holes 105 is greater than or equal to two, and at least two bolt holes 105 can ensure a firm connection between the base plate 100 and the mounting base. Of course, those skilled in the art can adjust the number of bolt holes 105 according to actual needs, for example, the number of bolt holes 105 can be three, four or five, etc.

[0057] Secondly, this application provides a household appliance.

[0058] The household appliances provided in this application include the display panels of any of the above-mentioned items.

[0059] With the above technical solution adopted, the display board of this application includes two main modules: a base plate 100 and a core board 200. The core board 200 integrates the main control chip 202 and the functional chip 203, and can be directly applied to different household appliances without any modification to the core board 200. To meet the differentiated needs of different household appliances, only simple base plate development is required, adjusting the display module 101 and the interaction module 102 of the base plate 100, and reserving a mounting area for the core board 200 on the base plate 100. After the base plate development is completed, the core board 200 is fixed on the mounting area, and communication between the base plate 100 and the core board 200 is achieved through an electrical connection between the second connecting component of the core board 200 and the first connecting component on the base plate 100. This configuration results in high versatility of the display board, which helps to shorten the development time of the display board and household appliances. Simultaneously, the core board 200 can be mass-produced, which helps to reduce production and maintenance costs.
