Please refer to Fig. 1, Fig. 1 is the structural representation with the first preferred embodiment of the mobile terminal looking squarely Presentation Function of the present invention.The mobile terminal 10 looking squarely Presentation Function that has of this preferred embodiment comprises treater 11, communication interface 12, digital light processing module 13 and projection lens 14.Treater 11 is for processing data; Communication interface 12 is for collecting auto meter data; Auto meter data, under the control of treater 11, are converted to data optical signal by digital light processing module 13; Projection lens 14 carries out looking squarely display for being projected to through data optical signal on windshield.
Please refer to Fig. 2, Fig. 2 is the structural representation with the digital light processing module of the first preferred embodiment of the mobile terminal looking squarely Presentation Function of the present invention.This digital light processing module 13 comprises LED light source 131, LED drive unit 132 and light processing unit 133.LED light source 131 is for providing display light source; LED drive unit 132 for according to auto meter data, driving LED light source 131; Light processing unit 133 is for being converted to data optical signal by the emergent light of LED light source 131.
Please refer to Fig. 3, Fig. 3 is the structural representation with the light processing unit of the digital light processing module of the first preferred embodiment of the mobile terminal looking squarely Presentation Function of the present invention.This light processing unit 133 comprises collimating lens 134, dichroic filter 135, optical integrator 136 and digital micromirror elements 137.Collimating lens 134 is for being converted to exiting parallel light by the emergent light dispersed of LED light source 131; Dichroic filter 135 for shunting exiting parallel light, to obtain the exiting parallel light of specific wavelength; Optical integrator 136 is for carrying out Homogenization Treatments to the exiting parallel light of specific wavelength; Digital micromirror elements 137, under the control of treater 11, carries out Digital Optical process, to form data optical signal to the exiting parallel light of the specific wavelength after Homogenization Treatments.
The following detailed description of the specific works principle with the mobile terminal looking squarely Presentation Function of this preferred embodiment.When chaufeur need to carry out data look squarely display time, the communication interface 12 of chaufeur usage data line by mobile terminal 10 and On-Board Diagnostics (OBD) interface (the OBD interface of automobile, OnBoardDiagnostics) connect, such mobile terminal 10 obtains auto meter data by communication interface 12.These auto meter data include but not limited to vehicle speed data, engine speed data, navigation data, system time data, tire temperature tire pressure data and driving rear-view device data.This communication interface 12 can be USB (USB, UniversalSerialBus) interface, HDMI (HDMI, HighDefinitionMultimediaInterface) interface or mobile terminal high-definition audio and video standard interface (MHL, MobileHigh-DefinitionLink) interface.
With preprocessor 11 control figure light processing module 13, auto meter data are converted to data optical signal.Be specially: LED drive unit 132 is according to auto meter data, and drive corresponding LED light source 131 to provide display light source, LED light source 131 here includes but not limited to red-light LED light source, green light LED light source and blue light LED light source.Then the emergent light of LED light source 131 is converted to data optical signal by light processing unit 133.
The process that the emergent light of LED light source 131 is converted to data optical signal is specially by light processing unit 133: first the emergent light dispersed of LED light source 131 outgoing is converted to exiting parallel light by collimating lens 134; The exiting parallel light of dichroic filter 135 collimation lens 134 outgoing subsequently carries out shunting process, and be about to the Transmission light allowing specific wavelength, other wavelength light reflect, to obtain the exiting parallel light of specific wavelength.Then the exiting parallel light of the specific wavelength of optical integrator 136 pairs of dichroic filters 135 outgoing carries out Homogenization Treatments, namely carry out space to the exiting parallel light of this specific wavelength to distribute again, making it to become more uniform flat-head type distribution from the distribution of a kind of high peak, thus space can be formed in can the exiting parallel light of relatively flat distribution.
Digital micromirror elements 137 (DMD, DigitalMicromirrorDevice) is under the control of treater 11 subsequently, carries out Digital Optical process to the exiting parallel light of the specific wavelength after Homogenization Treatments.This digital micromirror elements 137 surface has been covered with the small rotatable eyeglass of volume, this rotatable eyeglass is by rotating reflected light rays, each rotatable eyeglass once rotates and reflects a kind of color only, rotatable eyeglass as color purple pixel is only responsible for reflect red blue light on the projection surface, the rotatable eyeglass of salmon pink pixel is only responsible for reflect red green glow on the projection surface, the rotative speed of rotatable eyeglass can reach thousands of turns, such light is transmitted on screen can be caused illusion to the organs of vision of people by corresponding rotatable eyeglass, thus forms image on screen.
The data optical signal that digital light processing module 137 is formed is transmitted through on windshield by last projection lens 14, to realize looking squarely display.
So namely, the data with the mobile terminal 10 looking squarely Presentation Function completing this preferred embodiment look squarely display operation.
Preferably, in order to meet the needs of the chaufeur of different building shape and height, the projection lens 14 in this mobile terminal 10 can be mobilizable projection lens, to adjust the projection angle of projection lens 14.Mobile terminal 10 can be arranged on external adjustable fixed support in addition, by support bracket fastened angular adjustment, the projection angle of projection lens be adjusted.
Of the present invention have the mobile terminal of looking squarely Presentation Function by by built-in for digital light processing module mobile terminal, the treater of direct use mobile terminal carries out the conversion of data optical signal, make head-up display can be directly built-in with in mobile terminal, ensureing, on the basis that the display quality of head-up display requires, to reduce the cost of manufacture of head-up display.
Please refer to Fig. 4, Fig. 4 is the structural representation with the second preferred embodiment of the mobile terminal looking squarely Presentation Function of the present invention.The mobile terminal 40 looking squarely Presentation Function that has of this preferred embodiment comprises treater 41, communication interface 42, digital light processing module 43, navigation module 44 and projection lens 45.
The mobile terminal 40 of this preferred embodiment also comprises the navigation module 44 for obtaining navigation data on the basis of the first preferred embodiment.Such digital light processing module 43 can under the control of treater 41, the navigation data of auto meter data and navigation module 44 is converted to data optical signal, and user can the navigation data of navigation data as required in choice for use auto meter data or navigation module 44.Which further increases the display quality requirement of head-up display.
Below by a specific embodiment, the specific works principle with the mobile terminal looking squarely Presentation Function of the present invention is described.Please refer to Fig. 5 and Fig. 6, Fig. 5 is the concrete structure schematic diagram with the specific embodiment of the mobile terminal looking squarely Presentation Function of the present invention, and Fig. 6 is the concrete structure schematic diagram with the digital light processing module of the specific embodiment of the mobile terminal looking squarely Presentation Function of the present invention.
