Description
Technical field
The present invention relates to plane and the stereo-picture self adaptation handoff technique of a kind of large scale LED display, belong to bore hole and stand
Body Display Technique field.
Background technology
People are with the Liang Zhi eye observation world, and the scenery slightly difference seen due to right and left eyes, so the objective world seen is
Three-dimensional, therefore reduction real world is the target that the mankind pursue always.Stereo display technique may be used for military affairs, education,
The countries such as all many-sides such as amusement, medical treatment, are increasingly subject to the attention of countries in the world, US and European have all put into substantial amounts of power
Amount carries out the research of this respect, achieves the biggest achievement.Wherein stereo-picture Display Technique based on parallax technology is to realize
The advantage with technology maturation is facilitated to be widely used.
Traditional stereo display technique is non-for bore hole formula and Wearable two types.Wearable stereo display utilize timesharing, light splitting,
The corresponding two width pictures with parallax are delivered to the left and right eyes of people by the technology such as color separation respectively, are merged by brain and are formed very well
Stereo display effect, but its shortcoming is to need observer to wear relevant device, such as glasses etc., therefore to be user very
Inconvenience；And bore hole formula stereo display technique, it is not necessary to wear any auxiliary equipment, " ready to appear, body faces wonderland " can be appreciated
Approach scene, increasingly favored by people.On market, the bore hole formula stereo display technique of main flow is divided into slit shading type
With column mirror grating formula, slit shading type display screen light percent of pass is the highest by only 50%, and energy consumption is high, will be by market；
Column mirror grating relies on anaclasis principle, and therefore light percent of pass loses hardly, and this technology occupation rate is high.
For bore hole stereo technology, the size of display screen is the biggest, and produced third dimension is the strongest, more shake, along with LED
The technology of display screen reaches its maturity, and point, away from more and more less, meets the requirement of bore hole stereo display, therefore increasing public
Department puts into the stereo display of bore hole LED, but bore hole stereo display technique requires that corresponding display screen must input at least
2 pairs have the image of stereopsis, and the horizontal viewing distance that every secondary stereo-picture generally corresponds to is 65mm, for LED
For giant-screen, viewing distance all the scope of several meters even tens meters, the most only 2 secondary anaglyphs, level viewing away from
It is the most inadequate from only 130mm, therefore to meet multi-angle, many people bore hole stereo display requirement, typically uses
8 secondary or more anaglyph sequences so that level viewing is pleasant.But bore hole stereo display technique is also not without lacking
Point, along with the expansion resolution of horizontal view angle is reduced to originalN represents used anaglyph sequence number.
Therefore causing when display plane image, the content of plane picture is amplified by the refraction of bore hole stereoscopic column lens device, plane picture
Cannot see, have a strong impact on the operation to plane picture content.
Summary of the invention
The invention aims to solve the bore hole stereo technology of big display screen and exist when switching back into plane display, its plane picture
Unclear problem, it is provided that the LED display packing that a kind of plane/stereo mutually switches.
The LED display packing that a kind of plane/stereo of the present invention mutually switches, the stereo-picture of the method uses post mirror light
Gate technique realizes, and arranges post mirror device before LED display, and described post mirror device uses Lenticular screen to be attached to glass
Realize on glass plate,
The method comprises the following steps:
Step one, judge whether pre-display file is stereo-picture；Judged result is yes, performs step 2, switches to solid
Image display mode；Judged result is no, shows that pre-display file is plane picture, performs step 3, switches to plane graph
As display pattern；
Step 2, utilize retractor device to adjust distance D of LED display and the saturating device of post, make LED display be positioned at post
Near the focal position of lenticulation, i.e. meeting relational expression D=f ± 2mm, wherein f is the focal length of Lenticular screen；Broadcast
Return after discharging current file and perform step one；
Step 3, utilize retractor device to adjust distance D of LED display and the saturating device of post, and meet relational expression
D≤f/4mm；Return after playing current file and perform step one.
Advantages of the present invention: the bore hole LED three-dimensional display system that the present invention uses column mirror grating to be technology type, by knowing
The filename of other pre-display file, drives retractor device, control post mirror device to move forward and backward and realize plane picture and solid
The self adaptation switching of image, this programme advantage is that the bore hole solid LED screen using this device is not showing stereo-picture (3D
Image) time, do not affect people's normal operating to this system, plane picture (2D image) is clear and legible, i.e. this system with
Common LED giant-screen is without any difference, and the switching of screen picture and stereo-picture is that computer automatically controls, Ke Yigen
Adjust according to the content-adaptive play.Solve bore hole stereo display and differentiate the problem declined, for large scale bore hole stereo display
The development important in inhibiting of technology.
