Abstract

The invention provides a projection cellphone using light induction, which comprises a cellphone body and an input device. The cellphone body comprises a first wireless communication unit, a first signal processing unit, a projection unit, a voice input unit and a voice output unit. The first signal processing unit is respectively and electrically connected with the first wireless communication unit, the projection unit, the voice input unit and the voice output unit, and the projection unit is used for projecting images through lights with different light spectrums. The input device comprises a second wireless communication unit, a second signal processing unit and a light induction unit, the second signal processing unit is respectively and electrically connected with the second wireless communication unit and the light induction unit, the light induction unit is used for inducing the lights and generating input signals according to the light spectrums of the lights, and the second wireless communication unit is suitable for being communicated with the first wireless communication unit. The projection cellphone does not need a liquid crystal display screen and plastic keys, and is low in cost and convenient to operate.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a projection mobile phone. Background technique [0002] With the rapid development of science and technology, the life of modern people has entered an information age, and timely information communication has become very important. When instant communication is required, people generally choose traditional telephones or use cell phones. [0003] Traditional phones are usually non-movable fixed phones, and users need to stay in a fixed location before they can use the phone to communicate. As a new type of communication device, the mobile phone has replaced the traditional mobile phone to a large extent. It has the advantages of being portable and making calls anytime and anywhere. However, mobile phones also have disadvantages that traditional mobile phones do not have. For example, the cost of manufacturing LCD screens and plastic keys is relatively high, and the radiation is relatively larg...
