ELECTRONIC DEVICE AND INPUT DEVICE THEREOF
First Claim
1. An input device comprising:
- a key, the key comprising;
a first conductive film;
a second conductive film for cooperating with the first conductive film to generate a first electric field having a first predetermined intensity when the key is pressed;
a light source for emitting light;
a photoelectric transformer for generating a first electric signal when receiving light from the light source; and
a liquid crystal layer for transmitting the light to the photoelectric transformer under influence of the first electric field.

Abstract
An exemplary input device includes a key. The key includes a first conductive film, a second conductive film, a light source, a photoelectric transformer, and a liquid crystal layer. The second conductive film is configured for cooperating with the first conductive film to generate a first electric field having a first predetermined intensity when the key is pressed. The light source is configured for emitting light. The photoelectric transformer is configured for generating a first electric signal when receiving the light from the light source. The liquid crystal layer is configured for transmitting the light to the photoelectric transformer under influence of the first electric field. A related electronic device is also provided.
