Embodiment
As shown in Figure 1 3D glasses of the present invention and screen the coupling adjustment method, comprising:
A. two the first visible detection elements that are the photodiode structure are pasted respectively top and bottom position at the test screen lateral surface, outside friction tape capping, the impact of avoiding the external environment light belt is for detection of the picture of the starting and ending of a two field picture.The first visible detection element is converted to the signal of telecommunication with the light signal of described screen light source, voltage probe obtains the level of the first visible detection element institute switching electrical signals by the sample resistance that is connected with the first visible detection element of photodiode structure, and the waveform of described level is the image of a two field picture in the screen and opens waveform;
The second visible detection element that b. will be similarly the photodiode structure pastes the side at the 3D lens, the another side of 3D lens is provided with the arbitrary source of light emitting diode construction, the reception of 3D lens and transmitting synchronously of described test screen are set, the second visible detection element is converted to the signal of telecommunication with the light signal of described arbitrary source, obtain the level of the second visible detection element institute switching electrical signals by voltage probe, the waveform of described level is eyeglass and opens waveform;
C. by computer serial ports input debugging coded command ir xx 0xXX 0Xxx 1 order, wherein independent x value is 0～9, A～F is 16 hex value, xx represents the phase value of 3D lens, XX in first " 0xXX " represents that level is 50Hz or 60Hz, XX in second " 0xXX " represents the duty ratio of 3D lens, and 1 expression duty ratio is effective, and 0 expression duty ratio is invalid.The debugging coding adopts existing NEC coding, be used for adjusting the 3D synchronized transmissions code of test screen, thereby duty ratio and the phase place of synchronous change 3D lens make the image of expression left/right image open that waveform is can be respectively also complete to carry out correspondence in eyeglass is opened the time period that waveform all opens; And making the image that does not carry out described correspondence open waveform appears at eyeglass and opens in the time period of waveform Close All.
As shown in Figure 2, left image take the 3D lens is debugged as example, adopt the LCD screen of dividing from top to bottom 8 domain scannings, one two field picture equally to carry out the broadcast of 3D video image, choosing the brighter image of a pair in broadcast suspends, this image is debugged and test waveform, if the background frame brightness of choosing is lower, the wave-shape amplitude of test is just very little, is inconvenient to test.After each step debugging through said method, obtained waveform shown in Figure 2.As we can see from the figure, the eyeglass of test is opened waveform individual maximum level value, it is the acme that eyeglass is opened waveform, namely screen backlight just scans the image of top or bottom, along with the screen backlight order down scans, the level that eyeglass is opened waveform reduces gradually, and screen backlight is dimmed gradually, until can't see image." screen top eye image " among Fig. 2 and " screen lowermost end eye image " are all opened waveform at eyeglass low level place, so the left eyeglass of 3D lens be can't see eye image.
It is a two field picture that the image in 1 district～8 districts is opened waveform, the screen display left image out seen of left eye mirror namely, only have this two field picture (among figure eyeglass open the highest time period of waveform be the time period that the 3D lens is opened fully) within the time period that the 3D lens is all opened, human eye just can be seen a complete two field picture.If this two field picture is turned left, or toward moving right, namely image is opened waveform and is opened waveform with eyeglass and do not cooperate fully, the image of left-eye image is opened ripple will appear at rising edge or the trailing edge that eyeglass is opened waveform, this moment is owing to the left eyeglass of 3D lens is opened not yet fully or closed, parts of images information can't be seen by human eye (appearing at the image that eyeglass is opened waveform rising edge place), or see unnecessary image information (appearing at the image that eyeglass is opened the waveform falling edge), when this situation occurring, when watching 3D rendering, top graph picture or bottom diagram will occur and look like that ghost image is arranged, the phenomenon of flicker.
As can see from Figure 2, Δ t1 is the time interval (when namely screen backlight scan bottommost image) of the left eyeglass of 3D glasses when occurring to the left-eye image bottommost when opening 50%, if Δ t1 is less than 0ms, being illustrated in left eyeglass opened before 50%, left-eye image just out, so that just seen image in the opening process of left eyeglass, the image bottom that can cause seeing has scintillation (glasses open to 50% after see scintillation can not occur by image).Δ t2 also in like manner, if Δ t2, is illustrated in the image of seeing the top of screen in the closing process of left eyeglass less than 0ms, performance is the image top flicker.If Δ t3 is less than 0ms, the expression eye image appears in the process that left eyeglass opens, and namely left eye has been seen the image of right eye, and image appearance is ghost phenomena, Δ t4 in like manner, if Δ t4 less than 0ms, also ghost phenomena can occur.Therefore when debugging, need to make the value of Δ t1～Δ t4 equal＞0ms, just the phenomenon of the flicker of meeting removal of images and ghost image.
