In this embodiment, at least a portion of the display screen 20 may be directly exposed to the outside, the display screen 20 is a portion that can be touched by a user, the display screen 20 serves as a key cap, and the user can press the display screen 20. Optionally, the keyboard key may further include a key cap 10, the display screen 20 is disposed in the key cap 10, the key cap 10 is exposed to the outside, the key cap 10 is a portion that can be touched by a user, and when the user operates the keyboard key, the key cap 10 is touched by a finger of the user.
The display 20 is arranged inside the key cap 10, i.e. on the inner face of the key cap 10, instead of the front face of the key cap 10. Optionally, the accommodation depth of the key cap 10 is greater than or equal to the thickness of the display screen 20, so that the display screen 20 can be completely accommodated in the key cap 10, and the key cap 10 can sufficiently protect the display screen 20. According to the embodiment of the application, the display screen does not need to be subjected to glue sealing treatment on the front side of the keycap 10, and the attractiveness of the keyboard key is further enhanced.

Correspondingly, the key top 10 is provided with a light-transmitting portion for transmitting contents displayed on the display screen 20.
Illustratively, the display screen 20 may be an ink display screen, i.e., an electronic ink screen (E-ink screen). Alternatively, the electronic ink screen is composed of a substrate coated with electronic ink composed of numerous tiny transparent particles, the particles are formed by sealing a plurality of black (or other colors except white) and white particles with positive and negative charges in an internal liquid microcapsule, and the charged particles with different colors move in different directions due to different applied electric fields, so that the black or white effect is presented on the surface of the display screen.
In order to apply an electric field to the display panel 20, the display panel 20 needs to be electrically connected. Specifically, the display screen 20 is electrically connected to the conductive film 40 through the silicone key 30. Illustratively, the conductive film 40 is composed of an upper layer, a middle layer and a lower layer, the upper layer and the lower layer are respectively provided with circuit connecting wires and key contacts, and the middle interlayer is provided with round holes corresponding to the key contacts on the upper layer and the lower layer (the interlayer can prevent the upper layer and the lower layer from short circuit). The convex part on the silica gel key 30 corresponds to the key cap 10, and after the key cap 10 is pressed down, the convex part on the silica gel key 30 is downwards concave, so that the key contacts of the upper layer and the lower layer of the conductive film 40 are contacted (shaped like a switch is switched on), and a key signal is sent to the circuit board for processing.
In the present embodiment, the silicone key 30 also realizes the electrical connection between the display screen 20 and the conductive film 40. Specifically, as shown in fig. 4 and 5, one side of the display screen 20 is provided with a conductive contact 21, the silicone key 30 includes a conductive portion 31 and a non-conductive portion 32, and the silicone key 30 is electrically connected to the conductive film 40, for example, the silicone key 30 may be adhered to the conductive film 40 by a conductive adhesive.

Alternatively, when the number of the conductive contacts is plural, each of the conductive contacts 21 abuts on the conductive portion in one-to-one correspondence.
Further, as shown in fig. 2 and 3, the silicone key may include a conductive portion 31 and a non-conductive portion 32 which are spaced apart from each other. Wherein the non-conductive portions 32 are disposed between the conductive portions 31 to electrically insulate the conductive portions 31 from each other, thereby avoiding electrical shorts. Alternatively, the conductive portions 31 are uniformly disposed between the non-conductive portions 32.

Fig. 11 is a schematic structural diagram of a keyboard according to an embodiment of the present application. As shown in fig. 11, this embodiment further provides a keyboard, which includes the keyboard keys as described in any one of the embodiments of fig. 1 to 10.
As shown in fig. 11, the keypad includes 6 rows of keys, 4 of which are alphabetic keys, a row of numeric keys, and a row of function keys. However, as the size of terminals such as notebook computers is reduced, the keyboard space needs to be reduced.
In this embodiment, since the characters on the keyboard are displayed through the display screen, the display content of the display screen can be changed, so that one physical key can serve as a plurality of keys.
In one possible implementation, the display 20 of each keyboard key corresponds to at least one type of display content, and the display time of the different types of display content is different. I.e., each display screen 20 may display different types of display content at different times.
The display content can be in the types of numbers, letters, function identifiers, adjustment identifiers and the like, and the content displayed on the display screen of the keyboard keys can be switched through a switching instruction aiming at the keyboard keys.

Optionally, the keyboard comprises a first keyboard key and a second keyboard key. The display screen of the first keyboard key corresponds to one type of display content; the display screen of the second keyboard key corresponds to at least two types of display contents.
Specifically, for some common keys, the display screen of the common key corresponds to one type of display content to avoid frequent switching. For the keys which are not frequently used, the display screens of the keys which are not frequently used correspond to at least two types of display contents.
For example, if the alphabet key is a common key, the display screen corresponding to the 4 rows of keys where the alphabet key is located all displays one type of display content, and the alphabet key is a first keyboard key. Optionally, two conductive contacts are disposed on the display screen of the first keyboard key, one conductive contact is used as a power interface, and the other conductive contact is a signal interface for displaying content of an alphabet type.
For the second keyboard key, the display screen of the second keyboard key corresponds to two types of display contents, wherein one type of display contents is numbers and/or symbols, and the other type of display contents is function identification and/or adjustment identification.
Fig. 12 is a schematic structural diagram of a keyboard according to an embodiment of the present application. Fig. 12 shows a possible implementation manner of the second keyboard keys, and as shown in fig. 12, the third row of keyboard keys simultaneously corresponds to the content corresponding to the first row of keyboard keys and the second row of keyboard keys, that is, the content corresponding to the second keyboard keys provided in this embodiment includes the content corresponding to the first row of keys and the second row of keys in fig. 11. Thus, the keyboard corresponding to fig. 12 is implemented by reducing the number of rows of keys from 6 to 5, i.e., the first row of keys and the second row of keys in fig. 11 are reduced to one row of keys.
When the user needs to use the number and symbol keys, the display screen of the second keyboard keys is switched to display the numbers and symbols, the function identifiers and the adjustment identifiers are not displayed at this time, and the corresponding display mode is as that of the second row of keys in fig. 12. When the user needs to use the function and adjustment keys, the display screen of the second keyboard keys is switched to display the function identifier and the adjustment identifier, but the numbers and symbols are not displayed, and the corresponding display mode is as the display mode of the first row of keys in fig. 12.
Optionally, five conductive contacts are disposed on the display screen of the second keyboard key, where one conductive contact is used as a power interface, and the other four conductive contacts are used as signal interfaces of various types of display contents, for example, a signal interface corresponding to a number, a signal interface corresponding to a symbol, a signal interface corresponding to a function identifier, and a display interface corresponding to an adjustment identifier.
Optionally, there is a switch key in the first keyboard key; the switching key is used for acquiring a switching instruction of a user, and the switching instruction is used for indicating the display screen of the second keyboard key to switch the display content so as to display other types of display content different from the current type.
