[0038] At present, in the existing rice cooker display circuit board, there is usually a circuit board circuit with key operation and light display, wherein the touch chip MCU collects and processes the signals of the keys on the display board, outputs the key values ​​and transmits them to the main control chip MCU, and the main control chip MCU controls the display driver chip MCU to output a control signal to drive the light display of the display circuit according to the received key value information, thereby realizing the operation display of the human-computer interaction interface. However, in the above circuit, the main control chip MCU needs to complete the operation display of the human-computer interaction interface through the touch chip MCU and the display driver chip MCU respectively, which is costly, complex in circuit, and easily interfered.

[0039] In order to solve the above problems, the utility model proposes an operation display control component, referring to Figures 1 to 3 In one embodiment, the operation display control component includes:

[0040] Display device;

[0041] A button, used to output a corresponding trigger signal when triggered by a user;

[0042] An integrated controller 10, the integrated controller 10 comprises a trigger processing module 11 and a controller core 12, the trigger processing module 11 is electrically connected to the button, and the trigger processing module is used to process the received trigger signal and then output it;

[0043] The controller core 12 is electrically connected to the trigger processing module and the display device respectively, and the controller core 12 is used to control the display device to display according to the trigger signal.

[0044] In this embodiment, the display device can be implemented by a display device such as an LED display screen, a touch screen, a digital tube or an LED lamp. The display device is based on the control of the integrated controller 10 and is used to display information data corresponding to the trigger signal. For example, the display device can be implemented by an LED lamp. When the button is triggered by the user, the integrated controller 10 controls the LED lamp to light up after receiving the trigger signal, so that the user knows that the button is successfully triggered. The integrated controller 10 can also receive signals from other modules or circuits to control the display device to display corresponding information, such as temperature, air pressure, working current, working voltage, working time and other information parameters.

[0045] The integrated controller 10 can be implemented by using a microprocessor such as MCU, FPGA, CPLD, etc. The integrated controller 10 has a button information processing function and a display driving function integrated therein, that is, the original touch chip and display driving chip are integrated therein, so that the integrated controller 10 can process the received trigger signal when receiving the trigger signal output by the button, obtain the button key value information, and control the display device to display the corresponding information according to the button key value information. In this way, the original touch chip and the display driving chip are integrated in the integrated controller 10, so that the integrated controller 10 can directly receive the trigger signal output by the button, and directly control the display device to display the corresponding information after processing the trigger signal, thereby simplifying the circuit connection, reducing the cost of the operation display control component, and improving the response speed and reliability of the operation display control component. The integrated controller 10 may be composed of a trigger processing module 11 and a controller core 12, wherein the trigger processing module 11 is used to receive a trigger signal output by a key, perform signal processing on the received trigger signal, obtain key value information of the key, and send the key value information of the key to the controller core 12, and the controller core 12 performs logic processing on the key value information of the key to determine the control instruction issued by the user through the key, thereby controlling the display device to display the corresponding information. It is understandable that the controller core 12 can also send corresponding control instructions to other modules according to the trigger signal processed by the trigger processing module 11, thereby controlling the work of other modules to realize the corresponding functional operation. It is understandable that the number of keys can be multiple, and the user can send different trigger signals to the integrated controller 10 by triggering different keys, so that the integrated controller 10 performs different operations to realize different functions, or controls the display device to display corresponding information. For example, when the operation display control component is applied to a cooking appliance, it can be used to realize functions such as starting heating, stopping heating and keeping warm.

[0046] It is understandable that when the operation display control component is applied to equipment such as cooking utensils, the button and the display device can be set on the display panel of the housing of the equipment, and the integrated controller 10 can be set in the equipment. When the user presses the button, the button sends a trigger signal to the integrated controller 10 in the equipment, and the integrated controller 10 controls the corresponding module to work. At the same time, the integrated controller 10 can also control the display device to display corresponding information according to the trigger signal. For example, if the user triggers the button for controlling the start of heating, the integrated controller 10 controls the heating module in the equipment to start heating, and at the same time controls the display device to display the information "heating" to prompt the user that the button trigger is successful and the equipment is heating.

[0047] The utility model integrates the functions of the touch chip and the display driver chip into the integrated controller 10 by setting an integrated controller 10, so that the integrated controller 10 can directly receive the trigger signal output by the key, and after processing the trigger signal, directly control the display device to display corresponding information according to the trigger signal, thereby simplifying the circuit connection of the operation display control component, reducing the cost of the operation display control component, and improving the response speed and reliability of the operation display control component.

[0049] A trigger processing module 11, the trigger processing module 11 is electrically connected to the button, and the trigger processing module 11 is used to process the received trigger signal and then output it;

[0050] The controller core 12 is electrically connected to the trigger processing module 11 and the display device respectively, and the controller core 12 is used to control the display device to display according to the trigger signal.

[0051] Optionally, the integrated controller 10 further includes:

[0052] The display driver module 13 is electrically connected to the controller core 12 and the display device respectively. The display driver module 13 drives the display device to display based on the control output by the controller core 12.

[0053] In this embodiment, the integrated controller 10 is composed of a trigger processing module 11, a controller core 12 and a display driver module 13, wherein the trigger processing module 11 is used to receive the trigger signal output by the key, perform signal processing on the received trigger signal, obtain the key value information of the key, and send the key value information of the key to the controller core 12, and the controller core 12 performs logical processing on the key value information of the key to determine the control instruction issued by the user through the key, thereby generating a corresponding control instruction and sending it to the display driver module 13 to control the display driver module 13 to output the corresponding display signal and drive the display device to display the corresponding information. It can be understood that the controller core 12 can also send the corresponding control instruction to other modules according to the trigger signal processed by the trigger processing module 11, so as to control the work of other modules to realize the corresponding functional operation. In this way, the functions of the touch chip and the display driver chip are integrated in the integrated controller 10, so that the integrated controller 10 can directly receive the trigger signal output by the key, and after processing the trigger signal, directly control the display device to display the corresponding information according to the trigger signal, simplify the circuit connection of the operation display control component, reduce the cost of the operation display control component, and improve the response speed and reliability of the operation display control component.

[0054] Reference Figures 1 to 3 In one embodiment, the number of the buttons is multiple, and each button is used to output a corresponding trigger signal to the integrated controller 10 when triggered by a user.

[0055] In this embodiment, the number of buttons can be multiple, and the user can send different trigger signals to the integrated controller 10 by triggering different buttons, so that the integrated controller 10 performs different operations to achieve different functions, or controls the display device to display corresponding information. For example, when the operation display control component is used in a cooking appliance, it can be used to achieve functions such as starting heating, stopping heating and keeping warm.

[0056] Reference Figures 1 to 3 In one embodiment, the operation display control component further includes:

[0057] A communication module 20, the communication module 20 is electrically connected to the integrated controller 10, and the communication module 20 is used to establish a communication connection with an external module;

[0058] The integrated controller 10 is further configured to send a corresponding control signal to an external module through the communication module 20 according to the trigger signal, and to drive the display device to display according to the control signal received through the communication module 20 .

[0059] In this embodiment, the communication module 20 can select a wireless communication module 20 such as a WIFI module, a Bluetooth module, etc. to realize wireless communication connection with the outside, or can select a wired communication module 20 to realize wired communication connection with the outside. The user can output a trigger signal to the integrated controller 10 by triggering a button, and the integrated controller 10 determines the function that the user wants to trigger according to the trigger signal, and sends the corresponding control signal to the corresponding module through the communication module 20, thereby controlling the corresponding module in the device to work to realize the corresponding functional operation. For example, in a cooking appliance, the integrated controller 10 is connected to the heating control module through the communication module 20, and the user triggers the button to output the heating trigger signal to the integrated controller 10, and the integrated controller 10 sends the heating control signal to the heating control module through the communication module 20, thereby controlling the heating control module to start working to realize the heating function. Similarly, other modules in the device can also send signals to the integrated controller 10 through the communication module 20, so that the integrated controller 10 controls the display device to display corresponding information, such as time, temperature, air pressure, humidity and other information.

It can be understood that the buttons, display devices, and integrated controller 10 can be arranged on the same side surface of the display circuit board according to the actual application scenario, or can be arranged on both sides of the display circuit board. For example, the buttons and display devices can be placed on one side surface to facilitate users to trigger buttons and view display information of the display device, and the integrated controller 10 can be placed on the other side surface. Such a setting can reduce the area of ​​the circuit board, thereby reducing the volume of the operation display control component.
