Figure 17 describes the condition needed for the best 3D display effect of 3DLED screen. Display pixel and design of drive circuit and driving IC are on this pcb board 200, and the display pixel on this pcb board is 210. For the display pixel portion in 3DLED cell board, the distance between pixel and pixel is A1=A2. The distance that LED3D shows between cell board and cell board in module is C2+C1=A1=A2, and D1+D2=A1=A2, for the convenience of follow-up assembling, is D1=D2 and C1=C2 as much as possible.
Novel polarisation 3DLED shows the embodiment of module:
The manufacture method of present embodiment comprises the steps:
Step 1, embodiment according to above-mentioned set forth polarization type LED 3D, be fabricated to novel polarization type LED display screen. The display pixel of this novel polarization type LED display screen can be more than the display pixel of medium-sized polarization type LED display screen one times
Step 2, this novel polarisation 3DLED show that module shows the picture signal received respectively by the odd number row or column of display screen and even number row or column, and the odd number row or column particularly receiving odd-numbered frame image display screen shows. The even number row or column receiving even frame image display screen shows
Showing the image display pattern of module as Figure 18 describes this novel polarisation 3DLED, this novel polarisation 3DLED shows that the frame frequency of module is 120hz, and 91 is the first frame of image, and 92 is the second frame of image, and 93 is the N-1 frame of image, and 94 is the nth frame of image
Novel polarisation 3DLED shows the odd-numbered line of module or shows the left-handed rotatory polarization bar of stickup, even number line or show stickup dextrorotation rotatory polarization bar, when this display module receives the first two field picture, this display module odd number row or column shows, when showing that module receives the second two field picture, this display module even number row or column shows, by that analogy.
Therefore by above-mentioned control method, wear the Special spectacles with polarized lenses, left eye can only see the image of odd-numbered frame, right eye can only see the image of even frame, owing to the switch speed between picture frame and frame is very fast, and the persistence of vision effect according to human eye, so that it may so that brain perceives 3D stereo-picture.
Owing to the display pixel of LED display adds one times, display 3D video that therefore can be complete, do not have the problem that resolution reduces by half. Simultaneously because the refresh rate of this display screen reaches 120hz, thus without the problem having flicker. And this novel polarization type LED embodiment, if beholder need not watch 3D, directly takes away the glasses worn, controlling the signal of system transfers 2D to display screen, display screen end need not do extra process simultaneously.
The polarization type LED 3D display system of the present invention includes: receive extraneous video signal input processing module 660, polarization type 3D signal processing module 990, and transport module 800.
As shown in figure 19, after the extraneous video signal input processing module 660 of reception receives corresponding input signal, signal being processed, the input part such as the color of signal, brightness, noise abatement can be optimized process by this module, so as to the effect such as make the image of input more gorgeous, clear.
As shown in figure 20, after polarization type 3D signal processing module 990 receives the digital signal that extraneous video signal input processing module 660 is sent here, this module can be distinguished 660 modules and send true 3D signal or 2D signal during signal here, if true 3D signal does not just do the searching of the depth of field, if 2D signal during the signal brought, then start the looking up function of the depth of field, can the digital data transmission processed to DIBR module after above-mentioned process is complete, this module can be divided into signal complete for above-mentioned process two width picture signals of right and left eyes, then pass through the video format that the module of V3D meets the 3D signal syntheses of right and left eyes with LED3D display screen.
