Description
Technical field
The invention belongs to the electron and information technology field.The present invention designs a kind of smart mobile phone with projecting function, has improved the display capabilities of communication terminal.Technical solution of the present invention is integrated in mobile phone inside with the micro projector module, in conjunction with relevant Control Software, makes mobile phone have projecting function.
Background technology
Along with the development with smart mobile phone of improving constantly of wireless network transmissions speed, mobile phone changes the recreation terminal that can handle multimedia messages into from terminal that can only processes voice signals gradually.Present smart mobile phone comprise make a phone call, photograph, multiple function such as online and play multimedia video.Consider the portability and the production cost of mobile phone, the size of mobile phone and screen are often smaller.This has influenced the performance of mobile phone as recreation terminal.Because when everybody photo in seeing the mobile phone or film (or many people share the resource in the mobile phone), often wish that picture displayed can be big as much as possible.How to solve the contradiction between the little and user's request of mobile phone screen? the smart mobile phone with projecting function that we proposed will be expected to address this problem.
Micro projector is integrated in the mobile phone, just can will the image in the mobile phone or video project on the blank metope after amplifying, thereby solved the problem that display image is subjected to the mobile phone screen restriction.We also can be joystick of mobile phone configuration, and during in projection mode, available joystick is controlled display interface at operating handset.
The main operation principle of projecting apparatus is to send light by light source, by a series of optical lighting system, the light of light source is shone on the display chip uniformly.Signal is realized color range and GTG by Circuits System on display chip, demonstrate image, and after this projection lens by the projection front end projects the image multiplication on the display chip on the corresponding screen.
Little shadow casting technique is the extension of general shadow casting technique, realizes volume-diminished by reducing brightness requirement.Because adopted LED and two kinds of light sources of laser (led light source possesses highlighted power savings advantages, and LASER Light Source more possesses the high advantage of focusing accuracy) and LCOS and DLP two big shadow casting techniques, the size of micro projector is dwindled significantly.Compare with traditional portable projection machine, minitype projection machine is small and exquisite portable, and can project the image with the above two identical image quality in than short distance.
Although the development of micro projection technology is quite ripe, and some hand holding type miniature projecting apparatus also come out, but these projector equipments often all need specific data wire to link to each other with data terminal (as digital camera, notebook computer and mobile phone etc.), the competence exertion projecting function, this still makes the convenience of micro projector have a greatly reduced quality to a certain extent.
Summary of the invention
In order to remedy the defective of not adorning large-screen on the mobile phone and the micro projector shortcoming that is restricted of convenience to a certain extent, the present invention is intended to the micro projector technology is applied in the mobile phone, proposed the micro projector modularization is integrated in the implementation of mobile phone inside, make mobile phone have projecting function, the image projection of handset displays can be arrived any white background zone, projector distance is 1.5m-2m.We utilize existing micro projection technology that the micro projector module is integrated in mobile phone inside, utilize the MCU processor and the display controller of mobile phone inside simultaneously, finish the demonstration control and the operation control at mobile phone interface and projecting apparatus interface in conjunction with related software.
Technical scheme proposed by the invention comprises two parts, and first is the two interface display systems that are positioned at mobile phone inside, as shown in Figure 1; Second portion is outside auxiliary projecting apparatus interface control system (being projecting apparatus interface joystick), as shown in Figure 2.We utilize the MCU processor of mobile phone inside, cooperate to develop software accordingly, and display mode is divided into 3 kinds, are respectively the mobile phone interface display mode, projecting apparatus interface display mode and Expansion Interface display mode.Then, utilize display control module, finish relevant presentation control function with projecting apparatus interface joystick in conjunction with auxiliary keyboard.For three kinds of display modes, we utilize conventional keyboard can realize the control of mobile phone interface, as advance, retreat, operation such as page turning, again on this basis, we have added outside auxiliary projecting apparatus interface joystick, by infrared control signal being sent to the display controller of mobile phone inside, just can directly finish operation control to the projecting apparatus display interface.
Description of drawings
Two interface display control system of Fig. 1 mobile phone inside
The outside auxiliary projecting apparatus interface control system (projecting apparatus interface joystick) of Fig. 2
Embodiment
The inner two interface display systems of the mobile phone of first comprise: MCU controller, display controller, mobile phone interface, micro projector, keyboard controller (keyboard) and projecting apparatus interface infrared control signal receiver (as shown in Figure 1), first mainly finishes the selection of display mode and the controlled function of different display interfaces.
(1) MCU controller
The MCU controller is finished the selection of display mode and the work that data transmit.The MCU controller cooperates relevant developing software, and interface display is divided into three kinds of patterns, is respectively the mobile phone interface display mode, projecting apparatus interface display mode and Expansion Interface display mode.The MCU controller sends to display controller with associated control signal and data-signal, finishes the display interface controlled function under the different mode.
(2) display controller
Display controller is mainly finished the interface display controlled function under the different mode.Corresponding to different display modes, display controller receives control signal from the MCU controller, finishes the control to mobile phone interface and micro projector module.
The mobile phone interface display mode is normal mode of operation.Generally speaking, mobile phone is under this mode of operation, and under this pattern, display controller only need be controlled the demonstration of mobile phone interface.
The projecting apparatus interface display mode, promptly two interface display mode.Under this pattern, display controller will be controlled mobile phone interface and micro projector module respectively, make micro projector work, mobile phone picture be projected to any white background zone be shown; Meanwhile, display controller can also receive the control signal that projecting apparatus Interface Control infrared signal receiver transmits, and makes outside auxiliary projecting apparatus interface joystick can finish the direct control for projecting apparatus display frame.
