Keycap with invisible character effect, and production method and production method application thereof

Abstract

The invention relates to a keycap with an invisible character effect, and a production method and the production method application thereof. The keycap comprises a shading shell and a light transmission inner shell, the light transmission inner shell comprises an inner shell external surface, an inner shell internal surface and an inner shell thickness, the inner shell external surface is provided with at least a light transmission symbol portion with a micro protrusion and a flat portion, the light transmission symbol portion with the micro protrusion comprises an outer protruding light transmission surface and an inner concave light transmission surface and is used for generating a stereo perception and a wide light refraction range, the shading shell comprises a shell external surface, a shell inner surface and a shell thickness, and the shell inner surface is recessed towards the shell external surface so that the shell thickness is reduced and an intaglio symbol portion is formed. According to the keycap, the shading shell performs intaglio of a character pattern, when light emits in the keycap, the character pattern is displayed by the shading shell, the character on the keycap can be see whatever the light condition is, mimeograph is avoided, environmental protection and durability are achieved, and more importantly, the damage to eyes is avoided.

Description

technical field [0001] The invention relates to the field of computer accessories, in particular to a keycap with an invisible character effect, a production method and the application of the production method. Background technique [0002] The keys of electronic equipment are the most common command input methods, such as keyboards, keys in cars, keys of electronic equipment, etc. Among them, the keyboard is the most common computer input device, through which English letters, numbers, punctuation marks, etc. can be input into the computer , to issue commands, input data, etc. to a computer, etc. In order to meet the needs of development, keyboard developers began to research multi-functional keyboards. One of the important products is the luminous keyboard. The luminous keyboard is mainly reflected in the keyboard keys, and the letters on the keys can be seen clearly even when the lights are not turned on at night. [0003] The current keycaps are made of transparent mate...

AI Technical Summary

Problems solved by technology

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: it aims to solve the problem in the prior art that the spray paint on the surface of the keycap is easy to fall off after a long time of use, resulting in unrecognizable symbols, unrecognizable by users and normal use of the keyboard. Due to the defect of resource waste, the present invention engraves characters darkly on the inner surface of the light-shielding shell, and the light-shielding shell becomes very thin so that the light refracts to display the characters, and the light becomes soft after refraction without hurting the eyes
