Fig. 2 is the structural drawing of the micro embedded mobile terminal projection arrangement based on fiber medium transmission.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As depicted in figs. 1 and 2, bottom poly-dodging device, LED light source 1 is installed.LED is the english abbreviation of light emitting diode, is a kind of semiconductor electronic component that can be luminous, through the composite light source that trivalent and pentad form, it is little that LED has volume, and power consumption is low, long service life, high brightness, low in calories, environmental protection and the advantage such as sturdy and durable.
That what LED light source 1 sent disperse, uneven light, enters poly-dodging device 2; Light is integrated into that direction is substantially identical, the parallel beam of even intensity by poly-dodging device 2, and sends optical fiber to optics input optical fibre 3; The lens combination 4 being arranged on optics input optical fibre 3 other end receives the light that optics input optical fibre 3 sends, and repairs it and regulate light intensity.Optical fiber, as transmission light path, while simplification light channel structure, reduction volume, can also increase the life-span of projection arrangement, reduce energy resource consumption, good light transmitting fiber now, its optical transmission loss every kilometer only has point two decibel, that is propagates one kilometer of only loss 4.5% afterwards.
Light is undertaken repairing by lens combination 4, regulate light intensity after project on light engine 5.
Namely what the utility model light engine 5 utilized is current mature DLP technology, in DLP projector, image is produced by DMD, DMD arranges a matrix be made up of micromirror (accurate, miniature catoptron) on a semiconductor die, and each micromirror controls a pixel in projected picture.The quantity of micromirror conforms to the resolution of projected picture.These micromirror can change angle rapidly under the control of digital drive signals, once receive corresponding signal, micromirror will tilt 10 °, thus the reflection direction of incident light is changed.The micromirror being in projection state is illustrated as "ON", and tilts with digital signal+10 °; If micromirror is in non-projection state, be then illustrated as "Off", and tilt-10 °.Meanwhile, the incident light be reflected under "On" state by projecting lens by video-projection on screen; And the incident light be reflected under "Off" state in micromirror is absorbed by light absorber.
(basically, the angle of micromirror only has two states: "ON" and "Off".The frequency that micromirror switches between two states can change, and this light that DMD is reflected presents the various gray scales between black (micromirror is in "Off" state) and white (micromirror is in "On" state).DLP projector produces coloured image mainly through two kinds of methods, and these two kinds of methods are used in monolithic DLP projector and three DLP projector respectively.)
Like this, light engine 5 receives the signal from mobile terminal CPU, and utilize it to convert the light transmitted from lens combination 4 to image or video information, then these images or video information are transferred to projection lens 7 by the projection information output optical fibre 6 being arranged on light engine 5 other end.
This device volume is little, structure is simple, capacity usage ratio is high, transfer efficiency is high, be built in mobile terminal, improves energy utilization efficiency, simplifies light channel structure, really realizes the portable of micro-projector.
