[0002] In related technologies, some home appliances, such as food processors, typically have touch digital tubes installed on their display circuit boards to display numbers and enable touch functionality. However, traditional touch digital tubes are relatively large, which makes the display circuit board take up a lot of space. Utility Model Content

[0003] This application provides a display circuit board, a home appliance display screen, and a home appliance, which reduces the space occupied by the display circuit board.

[0004] This application provides a display circuit board, including a substrate, a controller, a conductive film, and a digital display component; the substrate has a plurality of light-transmitting holes penetrating the substrate, the digital display component includes a plurality of display lamps, the plurality of display lamps are fixed to the back side of the substrate and protrude into the light-transmitting holes; the conductive film is disposed on the surface of the substrate and is located at least around the light-transmitting holes; The controller is disposed on the substrate and electrically connected to the conductive film and the digital display component; the controller is used to control at least a portion of the display lamps of the digital display component to emit light when the conductive film is triggered, so as to display digital numbers.

[0005] The display circuit board of this application embodiment includes a substrate, a controller, a conductive film, and a digital display component. The digital display component includes multiple indicator lights. The multiple indicator lights are fixed to the back of the substrate and protrude into a light-transmitting hole. The controller is used to control at least some of the indicator lights of the digital display component to emit light when the conductive film is triggered, so as to display digital digits. Thus, there is no need to set up a touch-sensitive digital tube; the corresponding functions of a touch-sensitive digital tube can be achieved through the conductive film and multiple indicator lights. At the same time, due to the small overall size, the space occupied by the display circuit board is reduced.

[0006] Furthermore, the display lamp includes a light-emitting part and a pin part; the light-emitting part is housed within the light-transmitting hole, and the pin part is connected to the light-emitting part and fixed to the back side of the substrate; the light-emitting part is electrically connected to the controller through the pin part. In some embodiments, this reduces the thickness of the display circuit board, thereby further reducing the space occupied by the display circuit board. At the same time, housing the light-emitting part within the light-transmitting hole improves the display effect of the digital display.

[0007] Furthermore, the thickness of the light-emitting portion is less than the thickness of the substrate. In some embodiments, this prevents the light-emitting portion from being exposed from the front of the substrate, thus preventing damage from external forces.

[0008] Furthermore, the indicator light is a surface-mount LED. In some embodiments, the indicator light is thinner and lighter, which can further reduce the space occupied by the display circuit board.

[0009] Furthermore, the conductive film is disposed on the front or back side of the substrate. In some embodiments, the conductive film is disposed on the front side of the substrate, which improves the touch response. In some embodiments, the conductive film is disposed on the back side of the substrate, which helps prevent damage and enhances reliability.

[0010] Furthermore, the conductive film includes a copper foil disposed on the surface of the substrate and avoiding the light-transmitting hole. In some embodiments, this reduces costs.

[0011] Furthermore, the conductive film includes an ITO film, which is a semi-transparent film; the ITO film is disposed on the surface of the substrate and covers the light-transmitting hole. In some embodiments, this can increase the contact area and improve the touch control effect.

[0012] Furthermore, the display circuit board includes a plurality of the aforementioned digital display components. In some embodiments, this allows for the display of multiple digital digits, thereby increasing the amount of information displayed.

[0013] Furthermore, the controller is located on the back side of the substrate. In some embodiments, the substrate manufacturing process can be simplified, allowing the substrate to be tightly attached to the panel covering the front side of the substrate, avoiding light crosstalk issues. The display screen using the display circuit board does not need to use a light-blocking shell, and the thickness of the display screen can be reduced.

[0015] The display circuit board occupies little space, and the substrate can be closely attached to the panel covering the front of the substrate to avoid the problem of light leakage. Home appliance displays using display circuit boards do not need to use light-blocking shells, and the thickness of home appliance displays can be reduced.

[0023] The digital display component of the display circuit board in some embodiments of this application includes multiple indicator lights, which are fixed to the back of the substrate and protrude into the light-transmitting holes. A controller is used to control at least some of the indicator lights of the digital display component to emit light when the conductive film is triggered, so as to display digital digits. Thus, there is no need to set up a touch-sensitive digital tube; the corresponding functions of a touch-sensitive digital tube can be achieved through the conductive film and multiple indicator lights. At the same time, due to the small overall size, the space occupied by the display circuit board is reduced.

[0024] The following is a detailed description of a display circuit board, a home appliance display screen, and a home appliance according to an embodiment of this application, with reference to the accompanying drawings.

[0025] Figure 1 The diagram shown is a plan view of one embodiment of the display circuit board 10. Figure 2 As shown Figure 1 A partial cross-sectional view of the display circuit board 10 shown. See also Figure 1 and Figure 2 As shown, this application provides a display circuit board 10, which includes a substrate 11, a controller 12, a conductive film 13, and a digital display component 14.

[0026] The substrate 11 has multiple light-transmitting holes 15 penetrating the substrate 11. The light-transmitting holes 15 can be circular, square, or other shapes. Figure 1 In the illustrated embodiment, the light-transmitting hole 15 is an elongated hole extending vertically or horizontally. The digital display assembly 14 includes a plurality of display lamps 16, and in one embodiment, the display lamps 16 are surface-mount LEDs. This makes the display lamps 16 thinner and lighter, further reducing the space occupied by the display circuit board 10. The plurality of display lamps 16 can be arranged on the substrate 11 to form a digital graphic. In this embodiment, the digital display assembly 14 may include at least seven display lamps 16, and the at least seven display lamps 16 can be arranged to form the shape of the number "8", thereby the digital display assembly 14 can function as a single-digit LED display.

[0027] Multiple indicator lights 16 are fixed to the back side of the substrate 11 and protrude into the light-transmitting holes 15. At least one indicator light 16 may protrude into one light-transmitting hole 15, or two or more indicator lights 16 may protrude into one light-transmitting hole 15. A conductive film 13 is disposed on the surface of the substrate 11 and is located at least around the light-transmitting holes 15.

[0028] A controller 12 is disposed on the substrate 11 and electrically connected to the conductive film 13 and the digital display component 14. The controller 12 can be a microcontroller. In one embodiment, the controller 12 is disposed on the back side of the substrate 11. The manufacturing process of the substrate 11 can be simplified, and the substrate 11 can be tightly attached to the panel covering the front side of the substrate 11, avoiding the problem of light crosstalk. The display screen using the display circuit board 10 does not need to use a light-blocking shell, and the thickness of the display screen can be reduced. The controller 12 is used to control at least some of the display lamps 16 of the digital display component 14 to emit light when the conductive film 13 is triggered, so as to display digital numbers. Different parts of the multiple display lamps 16 can emit light to display different digital numbers. The user can touch the conductive film 13 to trigger the conductive film 13 and generate a sensing signal transmitted to the controller 12. The controller 12 can control at least some of the display lamps 16 of the digital display component 14 to emit light according to the sensing signal. In this way, there is no need to set up a touch digital tube. The corresponding functions of the touch digital tube can be realized by the conductive film 13 in conjunction with multiple display lamps 16, which effectively reduces costs and simplifies the manufacturing process. At the same time, due to its small overall size, the space occupied by the display circuit board 10 is reduced.

[0029] In one embodiment, the display circuit board 10 includes a plurality of digital display components 14. The plurality of digital display components 14 can be arranged side-by-side. This allows for the simultaneous display of multiple digital digits, increasing the amount of information displayed. The plurality of digital display components 14 can display numbers representing time, temperature, function, etc. In this embodiment, the display circuit board 10 includes four digital display components 14.

[0030] In one embodiment, the display lamp 16 includes a light-emitting part 17 and a pin part 18. The light-emitting part 17 is housed within a light-transmitting hole 15, and the pin part 18 is connected to the light-emitting part 17 and fixed to the back side of the substrate 11. The light-emitting part 17 is electrically connected to the controller 12 via the pin part 18. The light-emitting part 17 being housed within the light-transmitting hole 15 reduces the thickness of the display circuit board 10, thereby further reducing the space occupied by the display circuit board 10. Simultaneously, it improves the display effect of digital numbers.

[0031] In one embodiment, the thickness of the light-emitting portion 17 is less than the thickness of the substrate 11. This ensures that the light-emitting portion 17 is not exposed from the front of the substrate 11 and is not damaged by external forces.

[0032] In one embodiment, the conductive film 13 is disposed on the front or back side of the substrate 11. The conductive film 13 can be disposed on the front side of the substrate 11, which provides a better touch effect, while the conductive film 13 can be disposed on the back side of the substrate 11, which can prevent damage and make it more reliable.

[0033] In one embodiment, the conductive film 13 includes a copper foil disposed on the surface of the substrate 11 and avoiding the light-transmitting hole 15. The copper foil already on the substrate 11 can be used to achieve touch sensing, thereby realizing touch control functionality without the need for additional touch control devices, thus reducing costs.

[0034] In one embodiment, the conductive film 13 includes an ITO film, which is a semi-transparent film. The ITO film is disposed on the surface of the substrate 11 and covers the light-transmitting holes. This increases the contact area and improves the touch control effect.
