Array-type LED back light system 2 is located between speculum 3,4, and new line display screen 1 receives what is sent by array-type LED back light system 2
First pass through speculum 4 and reflex to speculum 3, then reflex to the light of new line display screen 1 by speculum 3 again, virtual eye is received
The light reflected by new line display screen 1, virtual eye 5 is in speculum 3,4 and array-type LED back light system 2 and comes back aobvious
The same side of display screen 1, it is aobvious positioned at coming back that virtual eye 5 receives the virtual image 6 observed after the light that new line display screen is sent
The opposite side of display screen 1.
Covered with one layer of uniform film on the eyeglass of above-mentioned new line display screen and virtual image the same side, for by array
The light that LED backlight system is sent reflexes to virtual eye.
Above-mentioned array-type LED back light system includes：LED/light source 7, tapered light pipes 8, Fresnel mirror 9, TFT screens 10 and diffusion
Plate 11；The LED/light source, emits beam, and realizes that high brightness, high uniformity are illuminated by tapered light pipes 8, Fresnel mirror 9 is suitable
In the convex lens for removing thickness, the light that tapered light pipes are launched further is restrained, so as to improve the light of whole backlight module
Luminance level, and diffuser plate 11 is eliminated as the glare produced by LED/light source and TFT screens.
When the light sensor probes of array-type LED back light system 2 change to extraneous brightness, system can be according to soft
Part algorithm LED drive circuit for adjusting electric current, so that the brightness of image and the brightness of environment are adapted.Sent when LED/light source 7
Brightness is adapted with environment and the light after equalizing light rays is passed through into full color TFT-LCD liquid crystal displays by speculum 3,4
Device, the imaged systematic reflection of display information to virtual eye 5, virtual eye 5 is clear positioned at front with regard to that can see through new line display screen 1
