Preferably, in this embodiment, the patterns and / or colors displayed in each of the display areas are different. Wherein, the display area displays patterns and / or colors under the illumination of the light source 4. When the light source is turned on, the pattern can be observed from the surface of the keycap 1. When the light source is turned off, the pattern cannot be seen from the surface of the keycap 1. The concealment is high, and after the light source is turned on, it can give people a sense of novelty, which is conducive to attracting consumers.

[0029] The luminous body 4 can be built into the keyboard itself and only wrapped by the keycap, or the keycap has an independent luminous body 4 built in, rather than a luminous body built into the keyboard. The luminous body 4 built into the keyboard belongs to the prior art. If the keycap has an independent luminous body 4 built in, it also includes a circuit board 2 and a vibration generator 3. The circuit board 2 and the vibration generator 3 are arranged inside the keycap 1. The vibration generator 3 is electrically connected to the circuit board 2. The circuit board 2 is provided with a luminous body 4. When the keycap 1 is struck, the vibration generator 3 supplies power to the circuit board 2 to light up the luminous body 4, and it can also ensure that the luminous body 4 has sufficient power. The luminous body 4 is a SMD packaged LED, which is welded on the circuit board 2; or, the LED luminous body is an LED wafer, which is packaged on the circuit board 2 in the form of a chip-on-board mounting. The circuit board 2 has a built-in power generation circuit. After being swung, the circuit board 2 generates electricity to light up the red, yellow and blue three-color lights, and flashes continuously for three to five seconds.

[0030] In this embodiment, if it is a space bar, since the space bar is long, most keyboard lights cannot cover the entire space bar, and avoid the position of the axis, and multiple light-emitting bodies 4 are built into the space bar.

[0031] Furthermore, the keycap 1 is made of a black translucent injection molded part, and the keycap 1 includes a key top 11 and a key skirt 12. The key skirt 12 is formed by extending downward in a direction perpendicular to or at a predetermined angle to the contour surface of the shell key top 11. In this embodiment, the surface of the key top 11 has a curved surface 111 that is concave inward or convex outward, and the curved surface 111 fits the curvature of the finger, thereby improving the user's operability.

[0034] In this embodiment, the back of the key top 11 is printed with anti-counterfeiting graphite with a pattern 114, and the pattern 114 can be customized according to the needs of the user. The key top 11 is snapped to the circuit board 2 through the buckle portion 1131 of the support frame 113, so that the circuit board 2 is suspended inside the key cap 1, and there is a space between the key top 11 and the circuit board 2 for placing the luminous body 4. In this embodiment, the luminous body 4 emits ultraviolet light, and the luminous body 4 is arranged in the space. The luminous body 4 is orderly distributed on the circuit board 2 along the length of the circuit board 2, so that the light inside the key cap 1 is sufficient. Among them, the light-emitting body 4 can be arranged on the circuit board 2 with the front side facing upward, and the light-emitting body 4 emits ultraviolet light to irradiate upward on the pattern 114 on the back of the key top 11.

The keycap 1 will also display the content of the pattern 114. At the same time, because the light is irradiated from the side, it will not directly enter the eyes, thereby protecting the user's eye safety.

[0035] In this embodiment, a plurality of sets of generator mounting accessories 31 are installed on the circuit board 2, and the vibration generator 3 is installed on the circuit board 2 through the generator mounting accessories 31.
