Abstract

The invention relates to a keyboard comprising a plurality of keys and a light source module, wherein any one key comprises a membrane switch structure, a scissors-type support member, a light accumulation and control elastic piece and a key cap; the light accumulation and control elastic piece is arranged in the space of the scissors-type support member, and the material of the light accumulation and control elastic piece includes a light accumulation material so as to achieve light accumulation function; after a power supply of a luminous source of the light source module is turned off, the afterglow of the light accumulation and control elastic piece can persistently give out light to illuminate the key cap.

Description

technical field [0001] The invention relates to a keyboard, in particular to a scissor-type membrane switch keyboard. Background technique [0002] In recent years, due to the rapid development of the information industry, many users may use portable information devices, such as notebook computers or personal digital assistants, in different environments. In a low-light environment, users may not be able to clearly see the numbers and characters marked on the keyboard keys, making operations difficult, and in severe cases, may even cause visual impairment due to barely recognizing the key marks. Therefore, the launch of the luminous keyboard can improve the inconvenience of using the keyboard in places with insufficient light. [0003] For example, Chinese Taiwan Patent No. M292120 discloses a structural improvement with a luminous keyboard. The keyboard area is made of transparent or translucent material, and the transparent material contains light storage powder, so that ...
