Description

Technical Field

[0001] This application relates to the field of display panel technology, and in particular to a display panel and a household appliance. Background Technology

[0002] Currently, display panels are used in various household appliances, such as refrigerators, especially those with sterilization functions. Intelligent display panels are gradually becoming a trend. Sterilization display panels show the sterilization progress, which can be displayed as "188" or "188%". However, these two different display modes—"number" (i.e., "188") and "number + percentage symbol" (i.e., "188%)"—must be implemented using two different circuit boards and their respective software methods, resulting in high design costs. Utility Model Content

[0003] Therefore, it is necessary to provide a low-cost display panel and home appliance that can realize two different display modes.

[0004] In a first aspect, a display panel is provided, comprising:

[0005] The LED assembly includes a first LED and a second LED;

[0006] The circuit board has drive pins and reset pins. The drive pins of the circuit board are connected to the first LED to drive the first LED to work, and the reset pins of the circuit board are connected to the second LED.

[0007] The touch button is connected in series in the power supply circuit from the reset pin to the second LED.

[0008] When the touch button is in the first state, the second LED is working; when the touch button is in the second state, the second LED is not working.

[0009] In one embodiment, the display panel further includes:

[0010] The outer shell has a first perforated pattern and a second perforated pattern;

[0011] The first LED bead is set in correspondence with the first hollow pattern so that the light beam emitted by the first LED bead is projected out from the first hollow pattern;

[0012] The second LED bead is positioned corresponding to the second hollow pattern so that the light beam emitted by the second LED bead is projected out from the second hollow pattern.

[0013] In one embodiment, the display panel further includes:

[0014] A light-blocking film is applied to the outer casing; the light-blocking film has a first light-transmitting area corresponding to a first perforated pattern and a second light-transmitting area corresponding to a second perforated pattern.

[0015] In one embodiment, the touch buttons are respectively disposed on other areas of the housing other than the first and second cutout patterns.

[0016] In one embodiment, the touch button is a self-locking button;

[0017] The first state of the self-locking button is the pressed state, and the second state of the self-locking button is the unpressed state.

[0018] In one embodiment, the touch button is a knob;

[0019] The first state of the knob is when the knob's indicator points to the first position; the second state of the knob is when the knob's indicator points to the second position, and the first and second positions are different.

[0020] In one embodiment, when the second LED is a multi-color LED, the display panel also includes multiple switches;

[0021] Among them, the multiple basic color pins of the multi-color LED bead support multiple basic colors one by one, and the number of basic color pins is the same as the number of switches.

[0022] Each multi-color LED has multiple basic color pins connected to one end of a touch button via multiple switches.

[0023] In one embodiment, when the second LED is a monochrome LED, there are multiple second LEDs and multiple touch buttons. The number of touch buttons is the same as the number of second LEDs, and the second LEDs are connected in a common cathode or a common anode configuration.

[0024] Secondly, a household appliance is provided, including an appliance body and the aforementioned display panel, the display panel being mounted on the appliance body.

[0025] In one embodiment, when the display panel includes a housing, the first cutout pattern is a number symbol and the second cutout pattern is a percentage symbol.

[0026] The aforementioned display panel and household appliance include a circuit board for an LED assembly and touch buttons. The LED assembly includes a first LED and a second LED. In the first state, both the first and second LEDs are active; in the second state, only the first LED is active. Therefore, the display panel can achieve two different display modes—"only the first LED is active" and "both the first and second LEDs are active"—based on a single circuit board and its corresponding software method, by enabling or disabling the touch buttons. This is simple and low-cost. Implementing two display modes based on a single circuit board and its corresponding software method also facilitates standardized management.

[0040] It is understood that the terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first LED may be referred to as a second LED, and similarly, a second LED may be referred to as a first LED. Both the first LED and the second LED are LEDs, but they are not the same LED.

[0041] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0042] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0043] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0044] In one embodiment, such as Figure 1 As shown, a display panel 10 is provided, including: an LED assembly 102, a circuit board 104, and touch buttons SW.

[0045] The LED assembly has a first LED 1022 and a second LED 1024.

[0046] The circuit board 104 has a drive pin and a reset pin. The drive pin of the circuit board 104 is connected to the first LED 1022 to drive the first LED 1022 to work. The reset pin of the circuit board 104 is connected to the second LED 1024.

[0047] The touch button SW is connected in series with the reset pin in the power supply circuit to the second LED 1024.

[0048] When the touch button SW is in the first state, the second LED 1024 is working; when the touch button SW is in the second state, the second LED 1024 is not working.

[0049] The first LED 1022 and the second LED 1024 can be arranged adjacent to each other. Specifically, the first LED 1022 is positioned to the left of the second LED 1024. This can be understood as follows: when the user faces the display panel 10 and observes the first LED 1022 and the second LED 1024 from the user's perspective, the second LED 1024 is located directly to the right, upper right, or lower right of the first LED 1022.

[0050] Since the drive pin of the first LED 1022 connected to the circuit board 104 is not the same pin as the reset pin of the second LED 1024 connected to the circuit board 104, the operation of the first LED 1022 and the operation of the second LED 1024 are independent of each other and do not affect each other. Therefore, the state of the touch button SW will not affect the execution of the software method corresponding to the circuit board 104. That is, whether the first LED 1022 is working alone or both the first LED 1022 and the second LED 1024 are working, the same circuit board 104 and the corresponding software method can be used.

[0051] Circuit board 104 is connected to the first LED 1022 via a drive pin, keeping the first LED 1022 constantly lit. Circuit board 104 is also connected to the second LED 1024 via a touch button SW, so that the touch button SW illuminates the second LED 1024 in the first state and extinguishes the second LED 1024 in the second state. Therefore, through the aforementioned display panel 10, by enabling or disabling the touch button, two different display modes can be achieved based on a single circuit board 104 and its corresponding software method: "only the first LED 1022 is in working state" and "both the first LED 1022 and the second LED 1024 are in working state". The implementation is simple and low-cost. Implementing two display modes based on a single circuit board 104 and its corresponding software method also facilitates generalized management.

[0052] In one embodiment, such as Figure 2 As shown, the display panel 10 also includes a housing 106.

[0053] The outer casing 106 has a first hollow pattern and a second hollow pattern.

[0054] The first LED bead 1022 is configured to correspond to the first hollow pattern, so that the light beam emitted by the first LED bead 1022 is projected out from the first hollow pattern.

[0055] The second LED bead 1024 is configured to correspond to the second hollow pattern, so that the light beam emitted by the second LED bead 1024 is projected out from the second hollow pattern.

[0056] There can be multiple first LED beads 1022. When there are multiple first LED beads 1022, they can be arranged in a matrix to display any number in the range of "0~100" by illuminating some or all of the first LED beads 1022. In this case, the first cutout pattern is correspondingly set to support the display of all numbers "0~100". When current flows through the first LED beads 1022 on the circuit board 104, the first LED beads 1022 are illuminated, and the beams of light from the first LED beads 1022 are projected from the first cutout pattern, allowing the user to observe any number in the range of "0~100" with the naked eye.

[0057] The second hollowed-out pattern can be a percentage sign. When the touch button is in the first state, the branch where the second LED 1024 is located forms a loop of "circuit board 104 → touch button SW → second LED 1024 → ground". That is, current flows through the second LED 1024 at this time, so that the second LED 1024 is lit. The light beam emitted by the second LED 1024 can be projected out from the second hollowed-out pattern. At this time, the user can observe the visual effect of the percentage sign being lit.

[0058] Therefore, when the touch button is in the first state, the display panel 10 can display a "number + percentage symbol", that is, a pattern display of any percentage value in the range of "0%~100%"; when the touch button is in the second state, the display panel 10 can display a "number", that is, a pattern display of any value in the range of "0~100". Figure 3 As shown, Figure 3 This is an illustration showing only the numbers "1~100". (Example) Figure 4 As shown, Figure 4 This is a diagram showing the numbers "1~100" and percentage symbols simultaneously.

[0059] In one embodiment, the circuit board 104 and the first LED 1022 ( Figure 5 The connection relationship between LED1~LED16 and the second LED 1024 can be found in [reference]. Figure 5 .

[0060] Among them, the SEG (Segment Pins) pin is a high-level drive pin, and the COM (Common Pin) pin is a low-level drive pin. The first LEDs 1022 form an LED array to achieve a digital display of "1~100". The RESET pin is a reset pin; by multiplexing the reset pin, the second LED 1024 can be turned on or off.

[0061] In one embodiment, the outer shell 106 can be a cast-in-place shell, or it can be an outer shell 106 formed by splicing together multiple sub-shells.

[0062] Of course, the outer shell 106 can also be made using other processes; the above is just an example.

[0063] In one embodiment, the display panel 10 further includes a light-shielding film.

[0064] A light-blocking film covers the outer casing 106; the light-blocking film has a first light-transmitting area corresponding to the first hollow pattern and a second light-transmitting area corresponding to the second hollow pattern.

[0065] The housing 106 of the display panel 10 is mounted on the circuit board 104 to protect the circuit board 104. The light-shielding film covers the housing 106, especially when it covers the housing 106 formed by splicing multiple sub-housings. This prevents the light beam emitted by the first LED 1022 and the light beam emitted by the second LED 1024 from leaking through the splicing gaps, and ensures that the light beam emitted by the first LED 1022 is projected only from the first light-transmitting area and the light beam emitted by the second LED 1024 is projected only from the second light-transmitting area, thereby optimizing the lighting performance.

[0066] In one embodiment, the touch button SW is correspondingly disposed on the housing 106 in areas other than the first and second cutout patterns.

[0067] like Figure 6As shown, the touch button SW can be set on the circuit board 104, that is, the touch button SW is deeply embedded under the housing, that is, the touch button SW is built into the internal structure of the display panel 10. During the assembly of the display panel 10, the operator performs button operation according to the production process guide issued by the R&D personnel (the process guide instructs the operator to determine whether a % display is required based on the product's input requirements, thereby determining whether the touch button SW needs to be enabled. Enabling the touch button SW means placing the touch button SW in the first state, and disabling the touch button SW means placing the touch button SW in the second state), and then completes the installation of the housing 106. With this setting, the user will only observe that the second LED 1024 is in a lit or off state, without requiring any user operation, thus preventing accidental triggering by the user.

[0068] like Figure 7 As shown, the touch button SW protrudes from the surface of the housing, that is, the touch button SW is placed on the surface structure of the display panel 10, so that users can choose to enable or disable the touch button SW according to their needs, satisfying various display needs and display preferences of users, thereby improving the flexibility of user settings.

[0069] Furthermore, the touch button SW is correspondingly located on the outer casing 106 in areas other than the first and second hollow patterns. This also prevents the touch button SW from obstructing the first and second hollow patterns, allowing the light beam emitted by the first LED 1022 to be projected onto the first hollow pattern without obstruction, and allowing the light beam emitted by the second LED 1024 to be projected onto the second hollow pattern without obstruction. This ensures the display effect and ensures that the display pattern observed by the user is only related to the distribution of the first LED 1022, the distribution of the second LED 1024, the first hollow pattern, the second hollow pattern, the first light-transmitting area, and the second light-transmitting area.

[0070] In one embodiment, the touch button SW is a self-locking button.

[0071] The first state of the self-locking button is the pressed state, and the second state of the self-locking button is the unpressed state.

[0072] When the self-locking button is pressed an odd number of times, it enters its first state, in which both the first LED 1022 and the second LED 1024 are lit, and they work together to display the information. Conversely, when the self-locking button is pressed an even number of times or not pressed at all, it enters its second state, in which the first LED 1022 is lit, the second LED 1024 is off, and only the first LED 1022 performs the display function.

[0073] The self-locking button remains in the open position after being pressed, so the user does not need to apply continuous pressure, making it more convenient to operate. It is suitable for display panels 10 that need to display percentage symbols for a long time or not display percentage symbols.

[0074] In one embodiment, the touch button SW is a knob.

[0075] The first state of the knob is when the knob's indicator points to the first position; the second state of the knob is when the knob's indicator points to the second position, and the first and second positions are different.

[0076] For example, taking the center point of the knob as the dot, the horizontal direction as the x-axis (with the right side as the positive direction), and the vertical direction as the y-axis (with the top as the positive direction), we can choose the direction pointing to the negative half of the x-axis as the location of the first position and the direction pointing to the positive half of the x-axis as the location of the second position. Alternatively, we can choose the direction pointing to the negative half of the y-axis as the location of the first position and the direction pointing to the positive half of the y-axis as the location of the second position. Figure 8 As shown, point A is the first position, and point B is the second position. When the knob's indicator points to A, the knob is in the first state, and the second LED 1024 is lit. When the knob's indicator points to B, the knob is in the second state, and the second LED 1024 is off. Besides the example above, any two different positions on the coordinate axis can be selected as the location of the first position and the direction pointed to by the second position; these will not be elaborated upon here.

[0077] It should be noted that the operating state of the first LED 1022 is completely unrelated to the state of the touch button SW. Therefore, whether the touch button SW is a self-locking button, a knob, or other form of triggerable module, it will not affect the normal operation of the first LED 1022. The aforementioned triggerable module can be manually adjusted to have two completely opposite states, one of which supports the transmission of electrical signals to the second LED 1024, and the other state supports the non-transmission of electrical signals to the second LED 1024.

[0078] In one embodiment, when the second LED 1024 is a multi-color LED, the display panel 10 also includes multiple switches.

[0079] Among them, the multiple basic color pins of the multi-color LED bead support multiple basic colors one by one, and the number of basic color pins is the same as the number of switches.

[0080] Each multi-color LED has multiple basic color pins connected to one end of a touch button SW via multiple switches.

[0081] By selecting to turn each switch on or off, the multi-color LED can display different colors. For example, the basic color pins of the multi-color LED include a red pin, a green pin, and a blue pin. When the switch connected to the red pin is closed, and the switches connected to the green and blue pins are both open, the multi-color LED displays red. Conversely, when the switch connected to the green pin is closed, and the switches connected to the red and blue pins are both open, the multi-color LED displays green. When the switch connected to the blue pin is closed, and the switches connected to the red and green pins are both open, the multi-color LED displays blue.

[0082] Furthermore, when the switches connected to the red and green pins are closed, and the switch connected to the blue pin is open, the multicolor LED displays yellow; when the switches connected to the red and blue pins are closed, and the switch connected to the green pin is open, the multicolor LED displays magenta. Of course, other color combinations can also be used to achieve different color displays for the multicolor LED, which will not be elaborated upon here.

[0083] In one embodiment, the first LED 1022 can also be a multi-color LED, thereby achieving different color displays for "188". The color-changing principle of the first LED 1022 is the same as that of the second LED 1024, and will not be described again here.

[0084] In one embodiment, when the second LED 1024 is a monochrome LED, there are multiple second LEDs 1024 and multiple touch buttons SW. The number of touch buttons SW is the same as the number of second LEDs 1024, and each second LED 1024 is connected in a common cathode or a common anode configuration.

[0085] By enabling or disabling the touch buttons SW, different brightness levels can be achieved for the second LED 1024. Specifically, the more touch buttons SW are enabled, the more second LEDs 1024 are illuminated, and the brighter the beam projected from the second hollowed-out pattern becomes.

[0086] Furthermore, the brightness adjustment of the first LED 1022 can also be achieved based on the brightness adjustment principle of the second LED 1024, which will not be elaborated here.

[0087] In one embodiment, such as Figure 9 As shown, a household appliance is provided, including an appliance body 20 and the aforementioned display panel 10, the display panel 10 being mounted on the appliance body 20.

[0088] The LED assembly 102 can be used in conjunction with the sterilization progress displayed on the household appliance. Specifically, the LED assembly 102 can display the sterilization progress of the household appliance in real time, thereby improving the visualization of the sterilization progress.

[0089] When the touch button SW is in the first state, the sterilization progress displayed by the household appliance is jointly displayed by the first LED 1022 and the second LED 1024; when the touch button SW is in the second state, the sterilization progress displayed by the household appliance is displayed by the first LED 1022 alone.

[0090] In one embodiment, household appliances equipped with sterilization functions include, but are not limited to, refrigerators, washing machines, air purifiers, dishwashers, and water dispensers. These household appliances can display the current sterilization progress on the display panel 10, improving the intelligence of the household appliances.

[0091] In one embodiment, when the display panel 10 includes a housing 106, the first cutout pattern is a number symbol and the second cutout pattern is a percentage sign.

[0092] When the touch button SW is in the first state, the sterilization progress of the household appliance is displayed as a percentage value, i.e., "0%~100%"; when the touch button SW is in the second state, the sterilization progress of the household appliance is displayed as a pure number, i.e., "0~100". Therefore, by enabling or disabling the touch button SW, the two display modes of the sterilization progress of the household appliance can be switched.

[0093] In one embodiment, the touch button SW may be built into the display panel 10, or into a home appliance.

[0094] When the touch button SW is in the built-in installation mode, it can prevent accidental triggering by the user and also prevent young children from frequently triggering the touch button SW, or even damaging the touch button SW.

[0095] In one embodiment, the touch button SW can be externally mounted on the display panel 10, or externally mounted on the housing of the household appliance.

[0096] When the touch button SW is in an external installation configuration, users can choose the appropriate display mode according to their needs without having to contact a professional assembler.

[0097] When the touch button SW is located outside the casing of the home appliance, it can be installed on the top of the appliance body 20 to prevent children from accidentally triggering the touch button SW and causing a change in the display mode; it can also be installed on the side wall of the appliance body 20 to reduce the visibility of the touch button SW. Of course, the touch button SW can also be installed in other locations outside the appliance body 20, which will not be elaborated here.

[0098] In one embodiment, the aforementioned household appliance further includes a reminder module 108.

[0099] The input terminal of the reminder module 108 is connected to the circuit board.

[0100] The reminder module 108 can provide reminders based on sterilization-related functions in the circuit board and corresponding software methods. Specifically, at multiple time points that require marking or reminding the user, such as the start or end of sterilization, the circuit board outputs an enable signal to the reminder module 108 to activate it.

[0101] The reminder module 108 can provide audio-visual reminders such as flashing lights and beeping sounds based on the audio-visual module. It can also send the sterilization progress of the refrigerator to electronic terminals such as mobile phones, computers, and wearable devices based on the communication module. Of course, the reminder module 108 can also provide reminders in other ways, and the examples above are not intended to be limiting.

[0102] For example, when the sterilization function is activated, the reminder module 108 can be turned on and be in a first working state; when the sterilization progress reaches 90%, the reminder module 108 can be in a second working state; when the sterilization progress reaches 100%, the reminder module 108 can be in a third working state, and then turn off. When the reminder module 108 is an indicator light, the first working state of the indicator light can be a red light, the second working state can be a yellow light, and the third working state can be a green light lasting 5 seconds. Of course, the reminder module 108 can provide sound and light reminders, send SMS messages, etc., at any point in the sterilization progress; the reminder module 108 can also be activated at any point in the sterilization progress when it needs to respond to changes in the sterilization progress.
