Description

Glasses type displayer

Affiliated technical field

The utility model relates to the glasses type displayer device in a kind of miniscope of electronic information, and instrument is watched or read in the independent amplification that also belongs in optics and the electronic applications.

Background technology

At present, the liquid crystal micro display screen divides two classes, and the miniature display screen of the liquid crystal on the first silicon chip (LCOS) has numerous advantages and is subjected to extensively paying attention to both at home and abroad, but the domestic conceptual phase that still is at present; It two is conventional TFT liquid crystal micro display screens, its technology maturation, and existing large-tonnage product is applied to every field, in digital camera, mobile phone.But all liquid crystal micro display screens are because image is too little, naked eyes can't be watched the image of more complicated straight, be not easy to carry and will make giant-screen, therefore make a precision, small and exquisite optical amplification system, the image of liquid crystal micro display screen is amplified, to form the clearly visible virtual big image of naked eyes, will be economic, practical, an effective industrial approach.The EYE-TREK of for example well-known glasses type displayer such as Japanese OLYMPUS company production in 1998, it is the device that the liquid crystal micro display image is amplified by the light path amplification system of the super resolution of optics (OSR) technical construction, the manufacturing cost height, technical difficulty is big.The relevant head mounted display of domestic patent just like: 99800073.6,00801152.4, all are display equipments of a kind of external hi-tech, they include complicated light path system and special liquid crystal micro screen is formed, price Gao Mao is difficult to adapt to domestic mass consumption.Domestic glasses type displayer patent is as 99232341.X, a kind of really device of too oversimplifying, and use the direct-injection type light path to amplify to be difficult to realize small size and intuitively clearly big image.

Summary of the invention

For the image with the liquid crystal micro display screen effectively amplifies, form a kind of virtual enlarged image, and physical dimension is little, technical difficulty is moderate, the utility model provides a kind of glasses type displayer device, and this glasses type displayer is by 1. liquid crystal micro display screens (TFT or LCOS), 2. reflective light path amplification system, 3. power-supply system, 4. outer signal input socket and signal converter are formed.It can not only form as the large-screen image more than 34 inches, and the spectacle-frame size of display has only 60 * 50 * 50 millimeters (monoculars), and 120 * 50 * 50 millimeters (binocular).

The technical problems to be solved in the utility model is: place a reflective amplification light path system in a little spectacle-frame, the image of existing liquid crystal micro display screen is effectively amplified, and it wants cube little, and image is amplified to more than 5-50 times, and image fault is little, and price is low.

The technical scheme that the utility model adopted is: adopt reflective light path amplification system, with people's eyeball as a specific eyepiece, the eyepiece of preposition again one group of magnifier, from the next high light of light source, be reflected into LCDs through spectroscope, the emergency light reflex image light on the liquid crystal display is on beam splitting lens (being 45 ° with liquid crystal display) is transmitted in groups eyepiece, project then on the retina of human eye, form the virtual image of multistage amplification.Why light path becomes 90 ° of propagation, and purpose is to reduce bulk effectively.

The beneficial effects of the utility model are, it is made up of miniature display screen (TFT or LCOS) and reflective optic amplification system, can on smaller physical dimension, realize amplifying clearly the virtual image, it can not only form as the large-screen image more than 34 inches, and the spectacle-frame size of display has only 60 * 50 * 50 millimeters (monoculars), and 120 * 50 * 50 millimeters (binocular).

Below in conjunction with drawings and Examples the utility model is further specified.
