The parallel slits size of grid 203, each signal grating 203 is different, and backlight 7, and backlight are equipped at the center that active belt 2 surrounds
Light is uniformly propagated to the inside of location hole 201 as light source by plate 7；The antetheca of external screen 1 is provided with barrier 102, external screen 1 it is interior
Portion is provided with multiple grating detectors 101, and grating detector 101 and location hole 201 are in same level；Advertisement screen protective shell
3 are fastened on the left and right ends of barrier 102, and advertisement screen protective shell 3 is internally provided with model 57BYG stepper motor 5 and model HF-
TGA-Y electric pushrod 4, stepper motor 5 are drivingly connected by belt wheel and active belt, and stepper motor 5 drives active belt 2 along external screen
1 rear wall carries out cycle operation, and the telescopic rod of electric pushrod 4 is flexible along the direction perpendicular to external screen 1, the telescopic rod of electric pushrod 4
Side close to external screen 1 is fixedly connected with brake pad；Wherein, the light project signal grating 203 of backlight 7 generates light letter
Number, grating detector 101 receives and identifies optical signal, and grating detector 101 is electrical with stepper motor 5 and electric pushrod 4 respectively
Connection.
By above technical scheme, backlight 7 provides light source and propagates to light in signal grating 203, and light is not through
After the parallel slits of same signal grating 203, the hot spot of different patterns is generated, hot spot is optical signal, thus optical signal
Type is all different, and each grating detector 101 is only capable of receiving and identifying the optical signal to match, advertisement drawing 202 with
When 102 Accurate align of barrier, grating detector 101 can receive specific identifiable optical signal, at this time grating detector 101
Electric signal is sent to two stepper motors 5, so that two stepper motors 5 shut down, while sending telecommunications to electric pushrod 4
Number, so that the telescopic rod of electric pushrod 4 is stretched out along the direction perpendicular to external screen 1, and drives brake pad mobile, thus brake pad
Piece is contacted and is braked with active belt 2, while advertisement drawing 202 and external screen 1 being fitted closely；When grating detector 101 connects
When receiving optical signal but can not identify, grating detector 101 does not send electric signal to control electric pushrod 4 and stepper motor 5, this
When, the telescopic rod of electric pushrod 4 is toward retraction, so that brake pad not driven to brake and consolidate active belt 2 and advertisement drawing
It is fixed, while stepper motor 5 remains in operation, driving active belt 2 continues to carry out cycle operation along the rear wall of external screen 1, to advertisement drawing
202 position continues to adjust, until the reception of grating detector 101 recognizes specifically recognizable optical signal, so that advertisement
Drawing 202 and 102 Accurate align of barrier show 202 content precise sharpness of advertisement drawing on external screen 1 to realize.
Embodiment 2
Referring to Fig.1, a kind of accurate display device of static naked eye tridimensional advertisement screen, it is substantially the same manner as Example 1, more into one
Step, advertisement screen protective shell 3 are internally provided with four active belt positioning columns 6, and four active belt positioning columns 6 are divided into two groups,
Every group two are respectively and fixedly installed to the inner wall of advertisement screen protective shell 3, and two groups of active belt positioning columns 6 are symmetrical arranged, active belt
