Projector for mobile phone and projection mobile phone

Abstract

The invention discloses a projector for a mobile phone and a projection mobile phone. A liquid crystal screen is arranged between a light source and a projection objective of the projector, and an interface of a screen line set of the liquid crystal screen is arranged on a shell. The other screen line set is arranged on a mobile phone circuit of the projection mobile phone and is the same as the screen line set connected with the mobile phone circuit and the liquid crystal screen, and an interface of the screen line set is arranged on the shell or a part exposed from the mobile phone circuit. The liquid crystal screen in the projector can receive and display signals which are totally as same as that of the mobile phone liquid crystal screen by connecting the mobile phone and the interfaces of the two screen line sets of the projector, and the signals are irradiated by the light source and projected to the screen through the projection objective. The projector, which directly uses an imaging element of the mobile phone, has a simple structure and low cost. The projection mobile phone connected with the projector realizes projection and play by means of the light source and the projection objective of the projector, and solves the problems of brightness and power consumption of the projection mobile phone.

Description

technical field [0001] The invention relates to a projector used for a mobile phone and a projection mobile phone matched with it. Background technique [0002] The triple play of telecommunication network, TV network and Internet has become the development trend of information technology.

AI Technical Summary

Problems solved by technology

[0007] If the projection mobile phone does not increase the power of the light source, but uses the light source and projection objective lens of the projector externally, it will not only have a simpler structure and low cost, but also will not cause excessive power consumption and brightness due to increasing the power of the light source. It is difficult to meet the requirements, or the playback time is too short
