Flexible membrane keyboard based on frictional machine and electronic product

Abstract

The invention discloses a flexible membrane keyboard based on a frictional machine and an electronic product. The flexible membrane keyboard comprises a key layer, a common layer and a signal processing circuit, wherein the key layer comprises a plurality of key areas which are independent from one another; each key area corresponds to a key and comprises a key electrode; the key electrodes are respectively connected with the signal processing circuit through key wires which are independent from one another; the common layer comprises a common electrode; the common electrode is connected with the signal processing circuit through a common wire; a frictional interface is formed between the key layer and the common layer; or the common layer comprises a structure for forming the frictional interface; or the key layer comprises a structure for forming the frictional interface. The flexible membrane keyboard is high in flexibility, is light and thin and can be conveniently used for various electronic products in an integrated manner.

Description

Technical field [0001] The invention relates to the field of electronic product peripheral equipment, and more specifically to a flexible membrane keyboard based on a friction generator and an electronic product. Background technique [0002] The keyboard is the main input device for electronic products such as computers. At present, the keyboard is mostly a rigid body made of plastic, which is not only large in size and inconvenient to carry, but also rigid keys are likely to cause finger joint disease for people who work with computers for a long time. Moreover, the rigid keyboard occupies a large volume, and it is difficult to apply to small electronic products, such as mobile phones, handheld computers and other electronic products. [0003] The flexible membrane keyboard is a keyboard with flexible characteristics, which can be folded or rolled up, is convenient to carry, and can be conveniently applied to small electronic products. At the same time, its input experience is ...

AI Technical Summary

Problems solved by technology

The current flexible membrane keyboard is mostly composed of four parts: the panel, the upper circuit, the isolation layer, and the lower circuit. Due to the limitation of the structure, the thickness is too thick and the flexibility is not enough.
