Light-transmitting key, light-transmitting keycap and light-transmitting keycap manufacturing method

Abstract

The invention relates to a light-transmitting key, a light-transmitting keycap and a light-transmitting keycap manufacturing method. The light-transmitting keycap is provided with a shading layer and a semi-transparent layer. The shading layer is provided with a hollowed-out pattern. The semi-transparent layer at least covers part of the hollowed-out pattern. The semi-transparent layer is provided with the light penetration rate ranging from 20% to 80% under the irradiation of the visible light and is provided with the color similar to the shading layer. In this way, when the backlight of the interior of a keyboard is switched on, sends out light rays and penetrates through the hollowed-out pattern, the brightness of the hollowed-out pattern is far greater than that of the shading layer, so that the hollowed-out pattern can be observed and identified easily; when the backlight is switched off, only the ambient light irradiates, the difference between the hollowed-out pattern, covered by the half-transparent layer, on the shading layer and other portions in visual sense is limited, so that the hollowed-out pattern is shaded and not obvious. The effect that the hollowed-out portion in the shading layer is shaded without the backlight is achieved, and the operation mode of the light-emitting keyboard can be identified effectively.

Description

technical field [0001] The present invention relates to a keycap and a manufacturing method thereof. Specifically, the present invention relates to a light-transmitting keycap for a luminous keyboard and a manufacturing method thereof. Background technique [0002] Due to the gradual popularization of luminous keyboards, users have increasingly strict requirements on the functions of luminous keyboards. see Figure 1a and Figure 1b , which is a schematic diagram of main layers of a conventional luminous keyboard. Such as Figure 1a As shown, the conventional luminous keyboard includes a key group, a metal base layer 25 , a light-shielding layer 23 , a light guide layer 22 , a backlight source 24 and a reflector layer 26 from top to bottom. Wherein, there are a plurality of keys 21 on the key group, and the light-transmitting keycaps 211 on the keys 21 are placed in a backlight environment by the light of the backlight 24, the light guide of the light guide plate layer 22 ...

[0004] However, with the diversification of the operating systems of computers, smart phones, and tablets, Ex: Microsoft, iOS, Android, therefore, some users have put forward requests, hoping to switch selectively through the wireless bluetooth interface of a single luminous keyboard. To communicate with electronic products of different operating systems to input text, but when the special function key symbols of each operating system are not used, the
