[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0023] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0024] The applicant found that:

[0025] Using a rotary encoder to adjust a parameter is a technical method that is widely used in various fields. However, generally speaking, a rotary encoder can only adjust one parameter, and during the parameter adjustment process, the parameter change cannot be known on the rotary encoder. Only after the parameter is adjusted and the system executes the corresponding adjustment action, the effect of the adjustment can be known, or the parameter can be seen on other screens.

[0026] The above existing technologies are not applicable to some special application scenarios. For example, on a DJ station, the operator only faces a keyboard with multiple rotary encoders, and each song may have different tone parameter settings. During the song switching process, each rotary encoder needs to be adjusted manually one by one to reach the preset initial value. The whole adjustment process is very cumbersome and not intuitive.

[0027] In view of this, in order to solve the above existing problems, firstly, referring to Figure 1 and Figure 2 , this embodiment provides an encoder with a display screen, including:

[0028] The knob part 1 is used to perform forward and reverse rotation actions to output corresponding electrical signals; for example, when the knob part 1 rotates forward, a corresponding first electrical signal is emitted, and when the knob part 1 rotates reversely, a corresponding second electrical signal is emitted;

[0029] The display screen 2 is arranged above the knob part 1 and is used to display the target parameter; when the operator rotates the knob part 1, the display condition of the display screen 2 located above the knob part 1 can be directly observed;

[0030] The data interaction module 3 is connected to the display screen 2 and the knob part 1 by signals, and is used to receive signal instructions issued by an external device or the knob part 1, and convert them into display signals for the display screen 2 to receive; the display screen 2 displays the target parameters after receiving the display signals.

[0031] An external device is used to send a signal instruction to the data interaction module 3. This signal instruction can be the initial value of the target object whose parameters need to be adjusted. After receiving this signal instruction, the data interaction module 3 converts it into a display signal for the display screen 2 to receive, so that the display screen 2 displays the target parameter after receiving the display signal. This target parameter is the initial value of the target object;

[0032] The knob part 1 is used to send a signal instruction to the data interaction module 3. This signal instruction is a parameter adjustment instruction of the target object. That is, when the knob part 1 is used to adjust the parameters, the data interaction module 3 can recognize the change of the electrical signal in real time, and then control the display screen 2 to timely adjust the displayed target parameters.

[0033] Regardless of whether it is through an external device or the knob part 1, the signal command issued can ultimately display the target parameters on the display screen 2, which is convenient for adjustment, and the adjusted parameters are intuitively visible.

[0034] Combination Figure 1 Optionally, a recessed area is provided at the center of the knob portion 1 , and the display screen 2 is embedded in the recessed area. The display screen 2 is located above the center of the knob portion 1 .

[0035] Combination Figure 2 Optionally, the knob portion 1 is hollow in the middle and has a through hole area in the center, and the lower structure of the display screen 2 is passed through the through hole area, which is equivalent to the knob portion 1 being located at the periphery of the display screen 2 and the knob portion 1 being sleeved on the circumference of the lower part of the display screen 2.

[0036] As an implementation mode, the display screen 2 is a liquid crystal screen, and the thickness of the liquid crystal screen is relatively thin. A cavity with an opening facing upward is provided at the center of the knob portion 1, and the liquid crystal screen is embedded and fixed in the cavity. The peripheral structure of the cavity is in a fixed state and will not rotate. The liquid crystal screen is equivalent to a cover, which is pressed on the cavity. When the knob portion 1 is rotated, the peripheral structure of the cavity will not rotate, resulting in the liquid crystal screen not rotating with the rotation of the knob portion 1. Therefore, when the knob portion 1 is rotated and adjusted, the liquid crystal screen remains stationary and the parameters displayed thereon will not rotate.

[0037] As an implementation mode, the data interaction module 3 includes a Bluetooth signal module, and the Bluetooth signal module is connected to the external device by wireless signal; preferably, the encoder is mounted on a keyboard, and when using this encoder, a mobile terminal such as a mobile phone is used to match it with its Bluetooth signal module. After the Bluetooth connection is established, the corresponding data can be transmitted to the Bluetooth signal module through the mobile phone to display the target parameters on the display screen 2.

[0038] Furthermore, a backlight strip is provided on the inner wall of the cavity of the knob portion 1 , and the backlight strip is electrically connected to the data interaction module 3 . An aperture is created by the backlight strip and is located below the outer edge of the display screen 2 , thereby enhancing the visual impact.

[0039] Reference Figure 3 In a second aspect, this embodiment provides a control method for an encoder with a display screen, which is applied to an encoder with a display screen as in the above embodiment, comprising:

[0040] The target object whose parameters need to be adjusted is set through the external device, and the initial value is set; the target object can be selected in the external device, and its corresponding initial value can be set;

[0041] Using an external device to send a signal instruction to the data interaction module 3;

[0042] The data interaction module 3 sends a display signal to the display screen 2 based on the signal instruction, so that the display screen 2 displays the target parameter as an initial value.

[0043] It should be noted that the external device can be a mobile phone terminal, which is connected to the data interaction module 3 by wireless connection, or a computer host, which is connected to the data interaction module 3 by wired connection. In short, the data interaction module 3 is a communication module that can receive external information, and after receiving the signal instruction, it can control the display screen 2 to display the target parameter;

[0044] Of course, the data interaction module 3 can receive external information and send its data to the outside. For example, when the real-time value of the target parameter is adjusted by the knob part 1, the data interaction module 3 can identify the adjustment action of the knob part 1, and send the corresponding adjustment electrical signal to the control host in the data format of the target parameter, so as to realize the actual adjustment of the parameter through the control host.

[0045] Preferably, the initial values ​​of different target objects can be set in the external device, which is equivalent to establishing an initialization parameter table of target objects and their initial values ​​in the external device. The parameter table is sent to the data interaction module 3 through one data transmission. The data interaction module 3 can set target objects in batches, such as volume, timbre, sound effects and other target objects, and reinitialize multiple parameters at one time, which is suitable for personalized customization application scenarios and is conducive to standardizing parameters and quickly writing them.

[0046] It should be noted that the above implementation method is suitable for scenarios where parameters need to be switched quickly. For example, when different people take turns to operate a device, different people have different standards and requirements for parameters. If different people are asked to operate it, they may need to readjust the parameters one by one. In this way, batch initialization can be achieved, which is convenient and fast.

[0047] As an implementation mode, a mapping relationship between a target parameter of a target object and a rotation action of the knob portion 1 is established through an external device;

[0048] Optionally, when the knob portion 1 is rotated one grid, a value change is adjusted;

[0049] Optionally, when the knob portion 1 is rotated by one, 5 numerical values ​​are adjusted;

[0050] That is, there is a mapping relationship between the change range of the target parameter of the target object and the rotation action of the knob part 1, and the corresponding mapping relationship can be adjusted according to the requirements of the change range of the parameters of different target objects;

[0051] The data interaction module 3 is used to read the electrical signal outputted after the knob part 1 rotates, and is converted into an adjustment instruction of the target parameter according to the mapping relationship, and the display screen 2 is controlled to update the target parameter based on the adjustment instruction.

[0052] For example, when the data interaction module 3 recognizes that the knob portion 1 has been rotated two steps in the positive direction, a corresponding adjustment instruction is generated through a mapping relationship, and the target parameter displayed on the display screen 2 is directly updated through the adjustment instruction.

[0053] Furthermore, in order to achieve the effect of switching and adjusting multiple target objects through one encoder when there are multiple target objects that need to adjust parameters, in this embodiment, the knob part 1 can also be controlled to move upward or downward to send a switching electrical signal; it should be noted that the parameter value of a specific target object can be adjusted by rotating the knob part 1 forward and backward, and different target objects can be switched by vertically pressing or lifting the knob part 1;

[0054] The data interaction module 3 controls the display screen 2 to switch the display to an initial value corresponding to the target object based on the target object switching sequence set by the external device.

[0055] Furthermore, after switching the display to the new initial value of the target object, the data interaction module 3 is used to read the electrical signal output after the knob part 1 is rotated, and the electrical signal is converted into an adjustment instruction of the new target parameter according to the mapping relationship corresponding to the new target object, and the display screen 2 is controlled to update the target parameter based on the adjustment instruction.

[0056] It should be noted that after using an external device to batch set the initial values ​​of the target objects, the display screen 2 will be set to a default target object display interface. When the knob part 1 is pressed vertically or lifted, it will switch to the next target object in the target object switching order and display its corresponding initial value. After the adjustment is completed by rotating the knob part 1, the adjusted data will be displayed on the display screen 2 and saved. The next time you switch to this target object, the adjusted target parameters will be displayed.

[0057] It can be seen that when there are multiple target objects whose parameters need to be adjusted, the target objects can be switched by vertically pressing or lifting the knob part 1, and the adjusted parameters will be saved.

[0058] As another implementation, a mapping relationship between a target parameter of a target object and a rotation action of the knob portion 1 is established through an external device;

[0059] The data interaction module 3 is used to read the electrical signal outputted after the knob part 1 rotates, and is converted into an adjustment instruction of the target parameter according to the mapping relationship, and is sent to the control host, and the control host performs the parameter adjustment action according to the adjustment instruction; because in the encoder composed of the data interaction module 3+knob part 1+display screen 2, the main action is rotation action+display action, and the control parameter that really needs to be changed is executed by the control host;

[0060] Preferably, the encoder is integrated in a keyboard, and the adjustment instruction is sent to the control host by using the main control chip of the keyboard, so as to achieve the adjustment of the parameters.

[0061] In addition, in addition to exchanging data with the data interaction module 3, the external device also exchanges data with the control host, uses the external device to read the current target parameters in the control host, and sends an update signal instruction to the data interaction module 3 to control the display screen 2 to display the current target parameters.

[0062] In some possible implementations, the data interaction module 3 corresponding to the encoder is a Bluetooth signal module. The communication range of the Bluetooth signal module is small and cannot receive signal feedback from a distant control host. Therefore, an external device is used as a converter to send an update signal instruction to make its display screen 2 display the current target parameters.

[0063] In a third aspect, this embodiment provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the above method when executing the computer program.

[0064] In a fourth aspect, this embodiment provides a computer-readable storage medium. The computer-readable storage medium may be a non-volatile computer-readable storage medium. The computer-readable storage medium stores a computer program, which, when executed by a processor, enables the processor to execute the above order management method.

Those of ordinary skill in the art can appreciate that the units and algorithm steps of each example described in conjunction with the embodiments disclosed herein can be implemented with electronic hardware, computer software or a combination of the two.

Whether these functions are executed in hardware or software depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the utility model.

[0066] In summary, compared with the prior art, the above embodiment provides an encoder with a display screen, which can use an external device or the knob part 1 to send a signal instruction to the data interaction module 3. The data interaction module 3 converts the signal instruction into a display signal for the display screen 2 to receive, and controls the display screen 2 located just above the center of the knob part 1 to display the target parameters, thereby realizing real-time updating of the displayed data and facilitating the operator to intuitively feel the data changes.
