Abstract

The invention discloses an electrophoretic display key structure. The electrophoretic display key structure uses a whole electrophoretic display film to serve as display of a plurality of key patterns, and is positioned on a printed circuit board with pattern electrodes; the whole periphery of the electrophoretic display film is sealed by sealant or a sealing material so as to prevent dampness or pollution, pictures can be displayed excellently, and the structure is easy to manufacture. Patterns to be displayed can be switched according to the mode, so that a user can easily and clearly discriminate words or patterns on the key.

Description

technical field [0001] The invention relates to a button structure, in particular to a button structure using an electrophoretic display film in the structure. Background technique [0002] Electronic products such as cell phones (Cell Phone), personal digital assistants (personal digital assistants, PDAs), etc. are usually provided with keypads. Keypads currently on the market can be divided into metal keypads and generally more common plastic keypads. The patterns of numbers, symbols and English characters on the keypads are usually made on the keycaps by printing or laser etching. On the upper surface, the pattern is easily peeled off and damaged under frequent pressing. In order to protect the pattern and increase the three-dimensional beauty, there is also a technique of forming the pattern on the lower surface of the keycap. Usually on the surface of limited electronic products, in order to save the area occupied by the keypad, each key will be assigned several patte...
