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 ...

AI Technical Summary

Problems solved by technology

[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, they must be hidden to indicate that they cannot function. For example: when the keyboard is connected to a PC with a Microsoft operating system, The function key symbols of the iOS operating system should be concealed and not illuminated, making it difficult to be observed

But when the keyboard is connected with the iPad of the iOS operating system, the function key symbols of the iOS operating system will be illuminated so that the user can easily observe
