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.

[0022] 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.

[0023] The applicant found that:

[0024] In the prior art, there is a method of embedding a display panel in the keyboard, setting the keycaps to be a light-transmitting material, buckling the keycaps on the display panel, using the display panel to display different contents, and seeing through the keycaps. However, this method will change the original structure of the keyboard, so that the display panel can be built into the keyboard, and the keyboard needs to supply power to the display panel, and the circuit structure needs to be changed, which is very inconvenient to use and has poor adaptability.

[0025] In view of this, in order to solve the above existing problems, firstly, referring to Figure 1 to Figure 2 The utility model provides a keyboard with variable keycap display content, comprising:

[0026] A keyboard body 1, on which a plurality of key caps 2 are arranged;

[0027] The electronic paper display module 3 has at least a part of its area as a display area, and the display area covers one or more key caps 2; the electronic paper display module 3 is an independent component, and can be detachably placed on the keyboard body 1;

[0028] Optionally, one electronic paper display module 3 is mounted on one key cap 2, and one electronic paper display module 3 has one display area, and the display area covers one key cap 2;

[0029] Optionally, one electronic paper display module 3 is simultaneously mounted on multiple keycaps 2, which may be the keycaps 2 in the letter area or the keycaps 2 in the number area, that is, according to the partitioning of the keycaps 2 on the keyboard body 1, the electronic paper display module 3 is adapted to the partitioning of the keycaps 2, and the same electronic paper display module 3 has multiple display areas. After the electronic paper display module 3 is mounted, the multiple display areas thereon cover the corresponding multiple keycaps 2;

[0030] The electronic paper display module 3 receives the display signal through wireless communication or wired communication, and displays it on the display area; first, the display area is not transparent. When the electronic paper display module 3 is mounted on the keyboard body 1, the display area covers and blocks the original content of the corresponding keycap 2, and the display side of the display area faces outward; then when the third-party terminal sends a display signal to the electronic paper display module 3 through wireless communication, the electronic paper display module 3 controls the display area to display the corresponding characters or patterns.

[0031] Optionally, when the electronic paper display module 3 adopts a wired communication mode, data transmission is performed through UART or SPI. Alternatively, when the wired communication mode is used, a wired power supply mode can be directly adopted to provide power to the electronic paper display module 3.

[0032] Optionally, when the electronic paper display module 3 adopts wireless communication, NFC near-field communication technology is adopted, and an NFC chip is integrated in the display area, so that data can be exchanged when approaching a third-party terminal to receive new display content. Furthermore, in addition to data transmission, NFC near-field communication technology can also transmit power and realize power supply.

[0033] As an implementation method, the display area is composed of an electronic ink screen, which has the advantages of small size and low power consumption. The electronic ink screen consumes power only when changing patterns or characters. After the pattern is changed, the electronic ink screen does not require power supply.

[0034] Embodiment 1:

[0035] The third-party terminal is a handheld mobile terminal; optionally, the handheld mobile terminal is a smart phone with NFC function, which can be used to edit relevant display content, and directly transmit data to the electronic paper display module 3 through the NFC function and display it on the display area.

[0036] Embodiment 2:

[0037] The keyboard body 1 is also provided with a first NFC module 4, which is wirelessly connected to the electronic paper display module 3. The first NFC module 4 is used to receive data from a third-party terminal, send a display signal to the electronic paper display module 3, and supply power to the electronic paper display module 3; specifically, the third-party terminal is a computer terminal, which edits relevant display content on the computer terminal and sends the relevant data to the first NFC module 4 in a wired or wireless manner; optionally, the first NFC module 4 is a component pre-built into the keyboard; optionally, the first NFC module 4 is an external component that is later connected to the keyboard and installed in a wired manner; this first NFC module 4 is connected to the electronic paper display module 3 signal through NFC near-field communication technology, uses the first NFC module 4 as data transfer, sends a display signal to the electronic paper display module 3, and supplies power to the electronic paper display module 3.

[0038] As an implementation mode, the electronic paper display module includes a connecting film and a display area, the connecting film is made of rubber, the display area is distributed and inlaid on the connecting film, the connecting film covers the keyboard body 1, and the display area thereon corresponds one-to-one with the keycap 2.

[0039] It should be noted that the structure of the electronic paper display module is similar to that of a keyboard protective rubber cover. On a rubber connecting film, multiple display areas are set according to the arrangement of the keycaps 2, and the display areas correspond to the keycaps 2 one by one. This method is convenient for directly installing an electronic paper display module on the existing keyboard to achieve variable display of the content displayed on the keycaps 2.

[0040] Of course, corresponding electronic paper display modules may also be provided for specific key caps 2 on the keyboard, such as the function keys F1 to F12.

[0041] On the other hand, the present embodiment provides a control method for keycap display content changeable, using a keyboard with keycap display content changeable as described above, comprising:

[0042] Receive a display signal sent by a third-party terminal, the display signal including customized display content; the third-party terminal sends the display signal to the keyboard through a wired or wireless communication method; when the third-party terminal is a handheld mobile terminal, the display signal is directly sent to the electronic paper display module 3 in the keyboard through a wireless communication method; when the third-party terminal is a computer terminal, the display signal is first sent to the first NFC module 4 in the keyboard through a wired communication method;

[0043] The electronic paper display module 3 displays the display content on the corresponding display area based on the display signal to realize intelligent update of the display content without changing the specific characters of the key cap 2 .

[0044] Embodiment 3:

[0045] The third-party terminal is a handheld mobile terminal; the handheld mobile terminal and the keyboard form an integrated control system;

[0046] The handheld mobile terminal is installed with a first application program, which is a specific APP program. The first application program is configured to have an interface for an operator to input display content and display execution objects. In the operation interface of the first application program, the operator can set the target display content. After the operation is completed, the first application program forms a display signal that can be wirelessly transmitted using NFC technology;

[0047] After the distance between the handheld mobile terminal and the electronic paper display module 3 is less than the first distance threshold, the handheld mobile terminal triggers the communication state and sends a display signal to the electronic paper display module 3. The display area receives the display signal and displays it.

[0048] Optionally, since each display area corresponds to an NFC chip, each NFC chip has a different identity tag, and each NFC chip represents a corresponding keycap 2, in the operation interface of the first application, the image or character displayed on the corresponding keycap 2 can be defined, and the display content can be associated with the position of the keycap 2 by customized means such as dragging and splitting, and a number of corresponding virtual NFC tags are formed through the first application, each virtual NFC tag is associated with the NFC chip of the display area corresponding to a specific keycap 2, and the virtual NFC tag will save the corresponding display content and form a specific display signal. When the handheld mobile terminal is brought close to the electronic paper display module 3, the corresponding virtual NFC tag will be called according to the NFC chip identity tag of the corresponding display area to transmit a specific display signal, thereby realizing directional transmission of the corresponding display signal to the specific display area, and facilitating batch definition of multiple display areas using a mobile phone.

[0049] Optionally, each time the handheld mobile terminal approaches the electronic paper display module 3 until the distance therebetween is less than a second distance threshold, the charging state is automatically triggered, and the display area on the electronic paper display module 3 is charged by the handheld mobile terminal through NFC technology.

[0050] That is, the NFC function of the handheld mobile terminal has two functions, one is data transmission, and the other is charging the display area on the electronic paper display module 3. Both use the distance as a trigger condition. Of course, the first distance threshold and the second distance threshold can be the same or different.

[0051] As an implementation method, a first application in a handheld mobile terminal can be associated with a second application. When the second application has a new push message, the first application can call this push information and remind in the display area on the specific key cap 2 of the keyboard, for example by flashing. If the operator wants to display it on the electronic paper display module 3 of the keyboard, he can touch this key cap 2, indicating that the keyboard is allowed to receive the display signal and obtain the operation permission of the first application. By simply placing the handheld mobile terminal close to the electronic paper display module 3 without turning on the screen, the push content can be transmitted to the electronic paper display module 3 and displayed on the display area.

[0052] Of course, the second application can be a weather forecast program, a chat program, a shopping program, etc. As long as the first application and the second application obtain operation permissions, the relevant text, images, links, etc. can be formed into a specific display signal and displayed on the display area.

[0053] Embodiment 4:

[0054] The third-party terminal is a computer terminal; the computer terminal and the keyboard form an integrated control system;

[0055] The computer terminal is installed with a second software, which is configured to have an interface for the operator to input display content and display execution objects. In the operation interface of the second software, the operator can set his target display content. After the operation, the second software sends a display signal to the first NFC module 4 on the keyboard body 1; the connection method between the computer terminal and the keyboard determines the method in which the second software sends data to the first NFC module 4, which can be a wired data transmission method, such as wired transmission with a USB data interface, or a wireless data transmission method, which is not limited here;

[0056] The first NFC module 4 sends a display signal to at least one display area in the electronic paper display module 3 according to the display signal; since the relevant data has been downloaded to the first NFC module 4 in advance, the first NFC module 4 can be a component set on the keyboard or an external component connected to the keyboard. The display signal is transmitted to the electronic paper display module 3 through the first NFC module 4, so that at least one display area displays specific content.

[0057] Preferably, the first NFC module 4 sends a display signal to the display area and charges the display area at the same time.

[0058] It should be noted that in Examples 3 and 4, the functions implemented are the same, but there are differences in data transmission. The computer terminal + first NFC module 4 in Example 4 is equivalent to the handheld mobile terminal in Example 3. In Example 4, content editing is performed in the computer terminal, and data is wirelessly transmitted through the first NFC module 4.

[0059] The above two embodiments are applicable to different application scenarios:

[0060] In Example 3, the display content of different display areas on the electronic paper display module 3 can be changed by using a handheld mobile terminal, and the method of use is relatively flexible; optionally, a handheld mobile terminal + electronic paper display module 3 forms a control system; optionally, a control terminal + a handheld mobile terminal + an electronic paper display module 3 forms a control system, and after using the handheld mobile terminal to change the display content of the display area, the control terminal is also used to functionally customize the corresponding keycap 2 to adapt to the display content, wherein the control terminal is a mobile phone or a computer, and is mainly used to re-functionally customize the keycap. Optionally, the user sets the information of interest on the mobile phone APP, and the APP pushes the relevant information to the electronic paper display module 3 after obtaining the relevant information through the network. For example, the customer wants to subscribe to weather information. Then the customer first sets the weather to be pushed to the electronic paper display module 3 in the APP, and when the APP actually obtains weather information every day, it is pushed to the electronic paper for display.

[0061] Embodiment 4 is applicable to application scenarios with computer terminals. Various software are installed on the computer terminals, including a second software for inputting display content and displaying execution objects, and a third software associated with the second software. The third software may be a weather forecast software, a chat software, a shopping software, etc. The relevant content of the third software may be read in the second software to form a corresponding display signal, and the signal is transferred through the first NFC module 4 and displayed on the display area.

[0062] Preferably, regardless of the third-party terminal, in a handheld mobile terminal or a computer terminal, the display content can be typeset, the display content can be divided into zones, the display area can be divided into zones, the display content after the typeset division can be bound to the display area after the zones, and the binding display relationship can be written into the display signal;

[0063] The electronic paper display module 3 displays corresponding display content on a specific display area based on the display signal.

[0064] This method of partition layout and partition content definition is conducive to content display management when displaying multiple parameters and realizes fast partition display.

[0065] Those skilled in the art can clearly understand that, for the convenience and simplicity of description, the specific working process of the above-described equipment, devices and units can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here. 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. In order to clearly illustrate the interchangeability of hardware and software, the composition and steps of each example have been generally described in the above description according to the function. 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.
