Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0053] Figure 1 This is a schematic structural diagram of a display control component according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 14 This utility model provides a display control component, including a display panel 10 and a mechanical trigger device 20. The mechanical trigger device 20 is fixedly disposed on the display panel 10. The display area on the front surface of the display panel 10 includes a first display area on one side of the mechanical trigger device 20 and a second display area on the corresponding other side of the mechanical trigger device 20.

[0054] In this embodiment of the invention, the user selects a function using a mechanical trigger device 20, and the corresponding function effect is displayed in the first or second display area of ​​the display panel 10. The mechanical trigger device 20 is simple and precise to operate, and the first and second display areas can meet the user's diverse function display needs. Taking a refrigerator as an example, this setup combines the advantages of both the mechanical trigger device 20 and the display panel to guide user operation, improving efficiency and the user's interactive experience with the refrigerator.

[0055] In some other embodiments of the present invention, the mechanical triggering device 20 is movably disposed on the display panel 10. The mechanical triggering device 20 has at least one moving position, and at the moving position, the display area on the front surface of the display panel 10 includes a first display area on one side of the mechanical triggering device 20 and a second display area on the corresponding other side of the mechanical triggering device 20.

[0056] In this embodiment of the utility model, the mechanical triggering device 20 is movable, and each movement position of the mechanical triggering device 20 corresponds to a function of the refrigerator. When the mechanical triggering device 20 is in a specific movement position, the function effect corresponding to this movement position is displayed in the first display area or the second display area of ​​the display panel 10.

[0057] In some other embodiments of this utility model, when a user selects a function through the mechanical trigger device 20 in the first or second display area, the corresponding function is highlighted.

[0058] In some embodiments of this utility model, the display area is a TFT (Thin Film Transistor) screen, i.e., a thin film field effect transistor.

[0059] In some embodiments of this invention, the front surface of the mechanical triggering device 20 has a third display area.

[0060] The third display area can display content related to the action of the mechanical trigger device 20, making the display control components and display panel look better and the function selection more intuitive.

[0061] In other embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the mechanical trigger device 20 has a hollow structure, and the display panel 10 has a fourth display area corresponding to the mechanical trigger device 20, so that the fourth display area is displayed forward through the mechanical trigger device 20. That is to say, the content displayed in the fourth display area on the display panel 10 corresponding to the position of the mechanical trigger device 20 can be directly observed by the user through the central control structure.

[0062] In some other embodiments of this invention, a transparent structure is provided in the middle of the mechanical triggering device 20, and a fourth display area is provided on the display panel corresponding to the mechanical triggering device, so that the fourth display area is displayed forward through the mechanical triggering device. This arrangement allows the content displayed in the fourth display area to be directly observed by the user through the transparent structure.

[0063] In some embodiments of this invention, the mechanical triggering device 20 is a knob, which generates corresponding control information by rotation. The user controls the knob to rotate at different angles, and different angles correspond to different functions. When the knob stops rotating, the refrigerator operates according to the control information at that time.

[0064] In some embodiments of this invention, the mechanical triggering device 20 is a button, which generates corresponding control information by pressing it. That is, the user selects refrigerator functions by pressing the button. For example, the control information corresponds to the number of button presses, and different numbers of presses are used to select the control information.

[0065] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the mechanical triggering device 20 is a movable block, movably mounted on the display panel 10, to generate corresponding control information through movement. The user controls the movable block to move to different positions, and different positions correspond to different control information. When the movable block stops moving, the refrigerator operates according to the control information at that time.

[0066] In some embodiments of this utility model, the mechanical triggering device 20 is arranged such that it selectively performs rotation to generate corresponding control information, presses to generate corresponding control information, or both rotation and presses to generate corresponding control information.

[0067] Furthermore, in some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the mechanical triggering device 20 includes a rotating cylinder 21, an elastic support device 24, and a signal generating unit.

The signal generating unit is configured to sense the rotation and pressing of the rotating cylinder 21. The mechanical triggering device 20 also includes a display screen 22, which is disposed inside the front end of the rotating cylinder 21. The elastic support device 24 is disposed inside the rotating cylinder 21. The signal generating unit includes a pressing signal generating unit 23 disposed at the rear end of the rotating cylinder 21.

[0068] In some embodiments of this utility model, the display screen 22 is a TFT (Thin Film Transistor) screen, i.e., a thin film field effect transistor.

[0069] In this embodiment of the invention, the rotating drum 21 is pressed and rotated. The user controls the rotating drum 21 to rotate at different angles, each angle corresponding to different control information. After the user controls the rotating drum 21 to rotate to a certain angle and releases the pressure, the elastic support device 24 causes the rotating drum 21 to return to its original position. The pressing signal generating unit 23 senses the function corresponding to the rotating drum 21 at this time and sends a control signal to control the refrigerator's operation. At the same time, the display screen 22 will also display the current function or information related to the current function.

[0070] Of course, in some other embodiments of this utility model, the signal generation unit may also be configured to simply sense the rotation or pressing of the rotating drum 21.

[0071] In some embodiments of this utility model, the pressing signal generating part 23 is made of conductive material and can generate an electrical signal.

[0072] In some embodiments of this utility model, the elastic support device 24 may be a compression spring.

[0075] In some embodiments of this utility model, such as Figure 10 As shown, the mechanical trigger device 20 is mounted to the display panel 10 by magnetic attraction. For example, a magnetic element 40 is provided between the display panel and the mechanical trigger device 20 to attract each other, and the magnetic properties of the magnetic element 40 are used to stably mount the mechanical trigger device 20 on the display panel. In some embodiments, the magnetic element 40 is a magnet.

[0076] In some other embodiments of this invention, as shown in 11, the mechanical triggering device 20 is mounted to the display panel 10 by a snap-fit ​​mechanism. For example, a snap-fit ​​mechanism 50 is provided between the display panel and the mechanical triggering device 20. The snap-fit ​​mechanism 50 includes a claw and a slot. In some embodiments, the claw is disposed on the mechanical triggering device 20, and the slot is disposed on the display panel 10. The mechanical triggering device 20 is stably mounted on the display panel by the snap-fit ​​of the claw and the slot. In other embodiments, the slot is disposed on the mechanical triggering device 20, and the claw is disposed on the display panel 10. The mechanical triggering device 20 is stably mounted on the display panel by the snap-fit ​​of the claw and the slot.

[0077] In some other embodiments of this utility model, as shown in 12, the mechanical triggering device 20 is mounted to the display panel 10 by adhesive bonding. For example, a rubber sheet with adhesive on both its front and back surfaces is disposed between the display panel and the mechanical triggering device 20, thereby ensuring the mechanical triggering device 20 is stably mounted on the display panel. Alternatively, a first Velcro fastener is provided on the display panel 10, and a second Velcro fastener is provided on the mechanical triggering device 20; the first and second Velcro fasteners are bonded together to connect the mechanical triggering device 20 to the display panel.

This arrangement, without affecting the display of the display panel 10, makes the mechanical trigger device 20 of a moderate size, and the overall proportions of the display panel 10 and the mechanical trigger device 20 appropriate and aesthetically pleasing.

[0084] In some embodiments of this utility model, such as Figure 13 As shown, the display panel also includes a first touch area 15, which is elongated and located on the same side as the first display area 13, the mechanical trigger device 20, and the second display area 14.

The first touch area 15 allows selection of a storage compartment with specific functions, such as a refrigerator, freezer, or variable temperature compartment. It also allows setting functions such as network connectivity, human body sensing, screen unlocking, and child lock.
