Problems solved by technology
[0004] The large-screen display technology of projection technology has become a direction for realizing large-screen display technology on mobile phones. However, due to the large size and power consumption of projectors, and the large differences between the data format and display mode of projectors and mobile phone applications, currently The method of using the projection technology to realize the large-screen display on the mobile phone is: the built-in data format conversion module on the mobile phone to realize the format conversion between the mobile phone display data and the projector data, and the display data output by the mobile phone is provided by a converter to output to the existing projector In fact, although this method realizes the large-screen display of mobile phone content, because the mobile phone and the projector are two independent devices, and the general projector is large in size, consumes a lot of power, needs AC power supply, and is not portable, so the The technical solution does not take advantage of the portability of the mobile phone and can be used anytime and anywhere, which greatly limits the scope of use of mobile phone large-screen projection

Embodiment Construction
[0021] Such as figure 1 The micro-projection display module, which is the core of the projection display mode, completes the projection display of the display content of the mobile phone or the projection display of the external input video input through the display switching module under the control of the baseband processor of the mobile phone.
[0022] The functions of the display switching module mainly include two:
[0023] 1) Display switching control: Under the control of the mobile phone processor, the switching between the LCD display and projection display of the mobile phone is completed; under the control of the mobile phone processor, the projection display switching between the content in the mobile phone and the external video input is realized.
[0024] 2) Working state control of the micro-projection module: Under the control of the mobile phone processor, the power control of the micro-projection display module is realized, so that the micro-projection displa...

The invention provides a mobile phone supporting projection modeled display, which can realize the projection display of the content or externally input video of the mobile phone by only using the mobile phone. The mobile phone supporting projection modeled display comprises a communication module of the mobile phone and also a micro projection display module and a display switching module, wherein, an input end of the display switching module is connected with exterior video input; signals output by a mobile phone base band processor in the communication module of the mobile phone is connected with the micro projection display module after being processed by the display switching module. When the mobile phone displays the content of the external video, the audio input externally can carry out real-time display by an audio amplifier and a loudspeaker inside the mobile phone.
Description
technical field [0001] The invention relates to a mobile terminal, in particular to a mobile phone supporting a projection display mode. Background technique [0002] With the rapid development of mobile communication networks and services, mobile phones have become an indispensable tool in people's daily life and work. With the development of technology, in addition to the basic call / short message functions, video playback, mobile TV, GPS navigation, music playback, mobile Internet access, etc. have increasingly become indispensable functions on mobile phones. As a portable device, the mobile phone has a small size and a small screen. When using the screen on the mobile phone to surf the Internet, watch movies, watch TV and other applications, it will greatly affect the viewing effect and user experience, greatly limiting the use of these services by users. . [0003] Projection technology, as a display technology for enlarging and displaying images, has been widely used ...
