Embodiment Construction

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the traditional key structure with backlight includes a key cap 1, an outer scissor frame 2, an inner scissor frame 3, an elastic element 7, a circuit board 4, a bottom plate 5 and a backlight module 6, and the key cap 1 is provided with character holes. The character display function can be realized through the backlight module. The present invention is improved based on the above-mentioned traditional button structure, and can realize switching and displaying of different characters.

[0021] The present invention provides a button for switching character display, such as figure 2 As shown, the keycap 1 of the first embodiment of the present invention includes the outermost UV layer 11 , the keycap body 13 inside the UV layer, the light-shielding layer 12 and the light-transmitting film 14 disposed inside...

Abstract

The invention discloses a key capable of switching display characters. The key comprises a key cap, scissor feet, an elastic element, a circuit board, a bottom plate and a backlight module arranged below the bottom plate, wherein different character holes are formed in the key cap, different light-transmitting films are arranged on the key cap, each light-transmitting film respectively correspondsto each character hole, and the light-transmitting film selectively transmits monochromatic light. According to the invention, switching display of different characters can be realized only by setting one light source, and multiple operation functions of the key can be realized through switching of different characters, so that the use experience of a user can be improved; and the key is simple in structure and has a good display effect, and the keyboard cost and the total energy consumption are reduced.

Description

technical field [0001] The invention relates to a button capable of switching and displaying characters. Background technique [0002] At present, most of the keyboard keys are printed characters, and long-term use will cause the characters to wear and fall off. The emergence of backlit keyboards has solved the above problems, but some keys with backlight functions can only display a single character, or, although there are multiple characters, multiple characters can only be displayed at the same time and cannot be switched. For example, for small computers, the span of the keyboard is small, which cannot display the current state, and the user experience is not good. For another example, for a keyboard with multiple functions for the same key, the key character cannot be switched and displayed, which also makes the user unable to determine the current state, which greatly reduces the user experience. Contents of the invention [0003] Purpose of the invention: The pres...
