In step 230, display 320 sequentially shows the first picture frame (such as normal picture frame f1), interference picture frame f1 ' and second
Picture frame (such as normal picture frame f2).
In one embodiment, as shown in Figure 5 B, display 320 disturbs picture frame f1 '~f60 ' to generate, and at each
Each interference picture frame f1 '~f60 ' is inserted between normal picture frame f1~f60 respectively, such as in normal picture frame f1 and normal picture frame
Insertion interference picture frame f1 ' between f2, the insertion interference picture frame f2 ' between normal picture frame f2 and normal picture frame f3, and so on.
It follows that after display 320 assigns interference picture frame f1 '~f60 ' to normal picture frame f1~f60, the quantity of total picture frame is by scheming
60 picture frames shown in 5A increase to 120 picture frames shown in Fig. 5 B.Therefore, the normogram played at one second shown in Fig. 5 A
During frame f1~f60, if this broadcasting frequency is set to the first broadcasting frequency, this first broadcasting frequency is 60fps (frame per
Second), on the other hand, normal picture frame f1~f60 shown in Fig. 5 B played at one second and interference picture frame f1 '~f60 '
When, if this broadcasting frequency is set to the second broadcasting frequency, this second broadcasting frequency is 120fps, it follows that second plays
Frequency is twice of the first broadcasting frequency, therefore overall picture can't be dimmed.
In one embodiment, processor 330 can generate algorithm by some known noises, such as in each normogram
Noise is added in frame f1~f60, to generate interference picture frame f1 '~f60 ', therefore is not repeated herein.

"on" position), when left shutter eyeglass 317 and right shutter eyeglass 319 are energized, left shutter eyeglass 317 and right shutter eyeglass 319
Shade effect is generated, for example, shows a completely black shade picture frame, therefore user A can not be fast by left shutter eyeglass 317 and the right side
Peephole piece 319 sees the image of interference picture frame f1 '~f60 '.In addition, shutter glasses 310 show normal picture frame in display 320
During f1~f60, left shutter eyeglass 317 and right shutter eyeglass 319 presentation off-position, therefore left shutter eyeglass 317 and right shutter glasses
Piece 319 will not generate shade effect.
It follows that the user A for putting on shutter glasses 310 will only see normal picture frame f1~f60, not can be appreciated that dry
Picture frame f1 '~f60 ' is disturbed, therefore, user A can't be interfered the interference of picture frame f1 '~f60 '.
On the contrary, as shown in Fig. 5 B~5C, the user B of shutter glasses 310 is not put on, then can be appreciated that all normograms
It frame f1~f60 and is assigned respectively to interference picture frame f1 '~f60 ' between each normal picture frame f1~f60, and disturbed picture frame
F1 '~f60 ' is disturbed, for example, user B is because the persistence of vision, it will be seen that encrypted encryption picture e1~e60,
In, it is sequentially to see normal picture frame f1 and interference picture frame f1 ', therefore, user's B brains in a short period of time due to the use of person B
Its institute can be thought because of the persistence of vision in the sea it is seen that encryption picture e1；Similarly, user B will be considered that its institute in brain
Sequentially it is seen that encryption picture e2~e60.
More specifically, it is the first broadcasting frequency (Fig. 5 A institutes in the second broadcasting frequency (broadcasting frequency corresponding to Fig. 5 B)
Corresponding broadcasting frequency) twice in the case of, before interference picture frame f1 '~f60 ' is not inserted into, as shown in Figure 5A, user
The image that B was seen in 1/60 second is, for example, normal pictures f1, and is assigned that will be inserted into interference picture frame f1 '~f60 ' to each
After between normal picture frame f1~f60, as shown in Figure 5 B, user B is in 1/60 second it will be appreciated that normal picture frame f1 and interference figure
Frame f1 ', therefore, in this 1/60 second, user B can think its institute it is seen that encrypting picture e1 (such as because of the persistence of vision
Shown in Fig. 5 C).
It is disturbed it follows that the user B for not putting on shutter glasses 310 can be disturbed picture frame f1 '~f60 ', it can not
Learn the content of correctly normal picture frame f1~f60.
In conclusion the peep-proof system and anti-peeping method shown in the present invention can allow the user for wearing shutter glasses to see
Normal display picture, the user without wearing shutter glasses are only capable of seeing the display picture after being disturbed.Further, since
This case need not set peep-proof piece, therefore will not lead to the problem of reduces light transmittance due to picture barrier line.More specifically, originally
Case carries out the masking of full frame by phased manner of shutter glasses by using shutter glasses, makes the user of wearing shutter glasses
