Description
Technical field
It is specially a kind of to realize that AR directly projects the side of display based on Micro LED the present invention relates to field of display technology
Method.
Background technique
The imaging system of AR system at present, core technology are LCOS (Liquid Crystal On Silicon) i.e. liquid
Brilliant attached silicon, is also liquid crystal on silicon, is a kind of based on reflective-mode and very small size of matrix liquid crystal display device.
The imaging of LCOS shadow casting technique uses reflection type optical path, uses in the product of early stage similar with one chip DLP
Timing imaging mode, but current main product generallys use higher three element sepatation of three-chip type RGB of imaging level
In combined imaging mode, imaging optical path and 3 chip DLP d-cinema projectors of million yuan of high-grade grades are essentially identical,
The LCOS imaging system of three-chip type, as shown in Fig. 2, the white light for first issuing light source, is divided by beam splitting system system
The light of red green blue tricolor, then, each primary colors light are irradiated on the LCOS chip of a blocks of reflecting, and system passes through control
The state of liquid crystal molecule changes the power of each pixel reflection light of the block chip on LCOS panel processed, finally passes through LCOS
The light of reflection pools Ray Of Light by necessary light refraction, is irradiated on screen by projector lens, is formed color
The image of color.
Need a white light source in the AR display system based on LCOS, and by light source by beam splitting system resolve into R,
G, B three primary colors are irradiated on LCOS again, for AR system, it is also necessary to which a beam splitting system, therefore, the AR based on LCOS show system
It unites more complicated, higher cost causes system power dissipation very high, directly affect simultaneously as needing the light source of a high brightness
The user experiences such as battery, system bulk, cruising ability.
Summary of the invention
The problem of for background technique, the present invention provides one kind to realize that AR is directly projected based on Micro LED
The method of display.
To achieve the above object, the invention provides the following technical scheme: a kind of realize that AR is directly projected based on Micro LED
The method of display, comprising the following steps:
S10: colored light is issued by MUC module control Micro LED；
S20: the light that Micro LED is issued is focused by speculating camera lens；
S30: the light after focusing is subjected to optical reflection and enters human eye.
As a preferred technical solution of the present invention, the power for the colored light that Micro LED is issued in step S10
It is controlled by MCU module.
As a preferred technical solution of the present invention, the light that Micro LED is issued in step S30 passes through polariscope
Carry out light reflection.
Compared with prior art, the beneficial effects of the present invention are: the present invention utilize Micro LED the characteristics of, can be significantly
It is huge to omit power consumption using its self luminous characteristic using Micro LED for complexity, power consumption and the cost for reducing current AR system
Big white light source, while beam splitting system is also eliminated, it is imaged by the high brightness of Micro LED, is projected directly at AR glasses
Imaging surface on, the cost substantially reduced, while imaging effect also significantly improves.
Detailed description of the invention
Fig. 1 is a kind of method flow schematic diagram that display is directly projected based on Micro LED realization AR provided by the invention；
Fig. 2 is that LCOS realizes that AR directly projects the method structure principle chart of display in the prior art；
Fig. 3 is a kind of method structure principle chart that display is directly projected based on Micro LED realization AR provided by the invention；
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1 and Fig. 3 are please referred to, the present invention provides a kind of method for realizing that AR directly projects display based on Micro LED, packet
Include following steps:
S10: colored light is issued by MUC module control Micro LED；
S20: the light that Micro LED is issued is focused by speculating camera lens；
S30: the light after focusing is subjected to optical reflection and enters human eye.
Micro LED, that is, LED miniatureization and matrixing technology, refer to the tiny ruler of the high density integrated on a single die
The LED array of degree, as LED display each pixel can addressing, be operated alone and light, Micro LED in fact it can be appreciated that its
Real is exactly by our the daily LED screen panels seen, miniature to 100 microns degree below, and single size is even not achieved
Originally the 1% of LED.The advantage of Micro LED is service life, brightness, and Micro LED is made of inorganic material, service life and steady
It is qualitative will be more much better than than LCOS screen, while having the characteristics that self luminous, possess the brightness than 100 times of LCOS high or more.
Therefore, using these features of Micro LED, can substantially reduce the complexity of current AR system, power consumption and at
This, omits the white light source of power hungry using its self luminous characteristic using Micro LED, while also eliminating light splitting system
System is imaged by the high brightness of Micro LED, is projected directly on the imaging surface of AR glasses.
In the specific implementation process, the power for the colored light that Micro LED is issued in step S10 is by MCU module control
System is mainly adjusted using pwm control signal by the duty ratio of the positive operating current of control LED using PWM technology
Save the light emission luminance of Micro LED.
In the specific implementation process, the light that Micro LED is issued in step S30 is anti-by polariscope progress light
It penetrates, it is simple for structure, it causes at low cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
