Abstract

The invention discloses a keyboard that comprises a key assembly, a key switch assembly and a semi-transparent film. The key assembly includes a transparent material layer, a non-transparent film, and a transparent elastomer layer. The key switch assembly consists of a substrate, at least a protrudent switch, and a light guide film (LGF). And the semi-transparent film is arranged between the transparent material layer and the LGF or is arranged at the upper surface of the transparent material layer, so that light that is refracted by a light guide lattice in a refraction region towards a corresponded light-transmitting pattern region can be shielded at least. According to the keyboard provided in the invention, a light guide lattice that is on an LGF in a refraction region can not be seen from the surface of a pattern; and light transmission in a light-transmitting pattern region is uniform; therefore, user experience is improved. In addition, the invention also brings forward a key assembly and a key switch assembly.

Description

technical field [0001] The invention relates to a key assembly, a key switch assembly and a keyboard, in particular to a mechanical keyboard, a key assembly and a key switch assembly. Background technique [0002] The keys of mobile terminals such as mobile phones usually transmit the light emitted by the LED to the predetermined light-transmitting pattern area through the optical light-guiding lattice set on the light guide film (LGF: light guide film), so that the light-transmitting pattern area can be illuminated. The pattern area, so that the user can see the pattern clearly. [0003] However, the inventors of the present application found in the process of researching and using the above-mentioned traditional keyboard that the characters on the above-mentioned keyboard will display the image of the optical light-guiding dot matrix on the light-guiding film, so that the transparency of the keyboard of the mobile terminal The light pattern area has uneven light transmiss...
