The picture of general LCD TV (LCD TV) is to be formed by a succession of tableaux continuous updating picture, because human eye has the ghost function, therefore, in a succession of tableaux continuous updating picture, can form a dynamic menu.The LCD TV frame updating has following several kinds: upgraded down to a left side, upgraded to the bottom right, from top to bottom upgrade and upgraded from the bottom to top by upper left by upper right.General LCD TV renewal frequency is 60hz (per second 60 times), and the human eye ghost is about 1/16-1/24 second (display frequency is 16hz-24hz relatively), therefore has the enough time to form dynamic menu.
Show three-dimensional picture (following three-dimensional is represented with 3D); At first; Must left and right picture alternately be interted and upgrade, and owing to be alternately to intert to upgrade, thus renewal frequency must to be promoted to the twice of human eye ghost frequency above to 60hz-120hz; Perhaps higher to 240hz, could let the action of human eye ghost continuously.Will need wear a shutter glasses when the 3D display is found out the 3D picture when human eye, this shutter glasses has a left shutter and a right shutter.When the reflector of the LCD TV of playing the 3D image was seen the signal of a renewal left eye picture off, the left shutter opening of shutter glasses was closed the right shutter of shutter glasses simultaneously, so the audience has only left eye to see picture.When the reflector of the LCD TV of 3D image was seen a signal that upgrades the right eye picture off, the left shutter close of shutter glasses was opened the right shutter of shutter glasses simultaneously, so the audience has only right eye to see picture.After brain merges the images of left and right eyes picture, the sense that produces solid.If left and right shutter opening overstand or too early open can produce the picture of ghost image, make the 3D effect variation, when serious even 3D effect can can't be reached; If the left and right shutter opening time of staying is too short or unlatching too late, then the 3D picture can be dim partially; Have only the accurate opening time just, can produce perfect 3D effect.
At first, please refer to Fig. 1, is the adjustment system sketch map that shows for 3D of the present invention.As shown in Figure 1, the adjustment system that 3D shows comprises a display 10, has a display screen 101; A plurality of first inductors 20 are that a pair of first inductor 20 is configured on the diagonal angle of rectangular display screen curtain 101 of display; And in preferred forms of the present invention, be on four corners, all to dispose first inductor 20; One 3D signal projector 30; Be electrically connected on the display 10; And dispose a calibrator 301; Wherein 3D signal projector 30 is in order to export the signal of a series of 3D image, and wherein the 3D signal of video signal that provided of 3D signal projector 30 is alternately to be repeated to show by a left eye test pictures 90 and a right eye test pictures 91, simultaneously; On the diagonal angle on each 3D signal of video signal 30; Dispose the pattern 901 of first color and the pattern 902 of second color, wherein inequality (for example: the pattern 901 of first color is dark to the color contrast look in the pattern 902 of the pattern 901 of first color and second color, and the pattern 902 of second color is light color (please refer to Fig. 3); One shutter glasses test bench 40; It is the place ahead one distance that is disposed at the display screen 101 of display 10; It has a placed side 401, and on the first end left and right sides side near display screen 101 of placed side 401, each places a left light source 50 and a right light source 51; And on the left and right sides side of placed side 401, respectively dispose a pair of second inductor relative with left light source 50 and right light source 51 with respect to the other end (i.e. second end) of first end, comprise left second inductor 70 and right second inductor 71; The left light source 50 of present embodiment is light-emitting diode (LED) with the optimal luminescent source of right light source 51, but present embodiment does not limit its light source type; One shutter glasses 60; Configuration one receiver (not being shown among the figure) on it; In order to receive the 3D image synchronizing signal that 3D signal projector 30 is sent; Make shutter glasses 60 to control the opening of shutter glasses 60 left mirrors 61 (ON) and to close opening (ON) and closing (OFF) of (OFF) and right mirror 62 according to 3D image synchronizing signal, wherein, shutter glasses 60 places between the two ends of placed side 401 of shutter glasses test bench 40; Be shutter glasses 60 left light source 50, right light source 51 and about relative second inductor 70, between 71; And the left mirror 61 of shutter glasses 60 disposes with left light source 50 and left second inductor 70 in line, and simultaneously, the right mirror 62 of shutter glasses 60 disposes with right light source 51 and right second inductor 71 in line.(for example: oscilloscope), its first detection signal input is electrically connected by lead 13 and a pair of first inductor 20 one waveform oscilloscope 80, and its second detection signal input is electrically connected by lead 15 and left second inductor 70 and right second inductor 71 simultaneously.
Then, please refer to Fig. 2, is the configuration schematic diagram for a plurality of first another embodiment of inductor of the present invention.Display screen 101 the place aheads at display 10 dispose a framework 11, and this framework 11 has a transparent area 111 and an edge 113 that is extended by transparent area 111 forward, and transparent area 111 forms a lid shape with edge 113.Transparent area 111 sizes equate with display screen 101, and live display 10 to fix framework 11 by edge 113 frames.A plurality of first inductors 20 then are installed in the transparent area 111 of framework 11, and the pattern 902 of the pattern 901 of first color and second color is corresponding on the position of its configuration and above-mentioned each 3D signal of video signal; For example: when each 3D signal of video signal only disposes the pattern 902 of pattern 901 and second color of first color on a diagonal angle; At this moment, promptly use the pattern 902 of pattern 901 and second color of first color on two first inductors 20 and the 3D signal of video signal corresponding; When four corners of each 3D signal of video signal all dispose the pattern 902 of pattern 901 and second color of first color, then need use four first inductors 20 to be configured in four corners of transparent area 111.The configuration of embodiment thus when another display unit of adjustment, only needs framework 11 direct removals are mounted to another display unit again and get final product, and can significantly reduce and change the required consumed time of first inductor 20 to another display unit.
A plurality of first inductor 20 of the present invention can be as shown in Figure 1; Directly be disposed on the display screen 101 of display 10; For example: use cohesive material a plurality of first inductors 20 to be pasted at least one diagonal angle of display screen 101 and with each 3D signal of video signal on the pattern of pattern and second color of first color corresponding; Or it is as shown in Figure 2; With a plurality of first inductors 20 be pasted on the transparent area 111 and with each 3D signal of video signal on the pattern of pattern and second color of first color corresponding, to this execution mode, the present invention does not limit.
Then, please refer to Fig. 3, is to be the 3D image test picture view of the present invention when carrying out adjustment.As shown in Figure 3, at the pattern 901 of upper right and left one first color of configuration down in four corners of left eye test pictures 90, the pattern 902 of configuration one second color on upper left and bottom right.And at the pattern colour 902 of upper right and left one second face of configuration down in four corners of right eye test pictures 91, the pattern 901 of configuration one first color on upper left and bottom right.As previously mentioned, most preferred embodiment of the present invention is to be a dark color with first color, and second color is a light color, distinguished by contrastive colours, but present embodiment does not limit to any color.When frame updating (as being upgraded down to a left side by upper right), the pattern 901 of upper right first color of left eye test pictures 90 can become the pattern 902 of second color earlier.And upgrade in the time of will finishing; The pattern 901 of first color under the left side can become the pattern 902 of second color; Left eye test pictures 90 promptly can become the upper right and left right eye test pictures 91 that is all the pattern 902 of second color down at this moment; And upper left and bottom right in succession variable color be the frame updating required time during this period of time.And a left side has become the upper right time that will change color once more of look to next time down, is retention time of picture.
Please refer to Fig. 4, is the sketch map for 3D signal of video signal axle update time of the present invention.If with general 120hz display is example, the frame updating time has 4 milliseconds (ms) approximately, and retention time of picture has 4.3 milliseconds approximately, that is frame updating is intact to have 8.3 milliseconds update time next time.Therefore; Picture such as need are complete to present perfect 3D effect; The left mirror 61 of its shutter glasses 60 or the opening time of right mirror 62 must be good more near 4.3 milliseconds of effects more; Be retention time of picture equal left mirror 61 or 62 opening times of right mirror (to explain a bit, because of very fast of the unlatching shutter speed of shutter glasses 60 left mirrors 61 of control or right mirror 62, so the shutter opening time need not add calculating).Then, shown in the time shaft T of Fig. 4, during 4 milliseconds of frame updating at the beginning; Left side mirror 61 is all closed condition with right mirror 62, and between about 3.95 milliseconds to 4 milliseconds, left mirror 61 can be opened and accomplish; So the time have only that left eye sees to picture (left eye test pictures 90), when to 8.3 milliseconds, left mirror 61 can be closed; Revert back to the frame updating state then, at this moment, left mirror 61 is all closing state with right mirror 62.The moment between time to 12.25-12.3 millisecond (be left mirror 61 close pass through the 3.95-4 millisecond again); Right mirror 62 can just be opened and accomplish this moment, have only therefore that right eye sees to picture (being right eye test pictures 91), when to 16.6 milliseconds (right mirror 62 unlatchings are again through 4.3 milliseconds); Right mirror meeting 62 is closed; Revert back to the frame updating state again again, left mirror 61 and the right mirror 62 of this moment are all closing state, according to this circulation.
In the renewal process of above-mentioned 3D signal of video signal; Because left eye test pictures 90 is inequality with the figure that right eye test pictures 91 disposes on the position in same corner; Therefore, it is also inequality to be positioned at the color contrast that first inductor 20 in same corner sensed, so its output is also inequality; For example: when first inductor 20 records the pattern 901 (being dark color) of first color of left eye test pictures 90; The signal of output one low state; And when being updated to right eye test pictures 91; When this same position was configured to the pattern 902 (being light color) of second color, then first inductor 20 was exported the signal of a high state, and this process produces first detection signal; Therefore, first inductor 20 can be sent to waveform oscilloscope 80 via lead 13 with this first detection signal with its signal condition that induces and show with the 3D frame updating of LCD; Clearly, the waveform of this its demonstration of first detection signal is to have square-wave signal high and low state.
Then, please refer to Fig. 5 A and Fig. 5 B, is the adjustment sketch map for the adjustment system of 3D demonstration of the present invention.At first; Shown in Fig. 5 A; In aforesaid LCD frame updating process, when the 3D frame updating was left eye test pictures 90,3D signal projector 30 can be sent to shutter glasses 60 with the signal of left eye test pictures 90; When the receiver of shutter glasses 60 receives the signal of left eye test pictures 90, at once left mirror 61 is opened (this moment, right mirror 62 still was a closed condition).Since the present invention place before the shutter glasses 60 about relative left light source 50 and right light source 51 be irradiation source forever, and its light facing to shutter glasses 60 rears about a relative left side second inductor 70 and right second inductor 71.With Fig. 5 A is example, and when aforesaid left mirror 61 was opened, its left second inductor 70 can be sensed the light of the left light source 50 in the place ahead; Clearly, still be closed condition because of right mirror 62 this moment, so right second inductor 71 can't be sensed the light of the right light source 51 in the place ahead.Therefore; Open and detect light to left mirror 61 when left second inductor 70 from left mirror 61 and close (being updated to right eye test pictures 91); Be the left retention time of picture of 3D image during this period of time; And this induced signal just can be sent to waveform oscilloscope 80 demonstrations with lead 15 with this second detection signal via left second inductor 70, and the waveform of its demonstration can be to have square-wave signal high and low state.And at the same time, first inductor 20 also can transmit waveform oscilloscope 80 via lead 13 with first detection signal with the induced signal of the 3D frame updating of LCD and show.At this moment, just can open initial point by first detection signal that is shown on the waveform oscilloscope 80 and the waveform between second detection signal judges whether synchronously; Whether the opening time of promptly judging the left mirror 61 of shutter glasses 60 meets 4.3 milliseconds on the display 10.And Fig. 5 B shows that the 3D frame updating is the sketch map of right eye test pictures, because its process is identical with the test process of Fig. 5 A, so repeat no more.
If when first detection signal that is shown on the waveform oscilloscope 80 and the waveform between second detection signal open initial point when asynchronous; Represent that promptly receiver that LCD sends out the time point of establishing the 3D test pictures that device sees off and shutter glasses 60 opens that generation time postpones (time lag) between the time point of left eye; The opening time that promptly can cause left mirror 61 this moment is also during 4.3 milliseconds of no shows; The signal of next frame update is closed left mirror 61; So when the time delay between first detection signal and second detection signal is long more, represent that promptly the opening time of left mirror 61 is short more, therefore can cause aforesaid 3D picture inclined to one side dimness of meeting and deleterious; Likewise,, then can produce the picture of ghost image, make the 3D effect variation if when the opening time of left mirror 61 is long more; Have only the accurate opening time just, can produce perfect 3D effect.
So imitating device when accent of the present invention is shown by waveform oscilloscope and judges the 3D retention time of picture to some extent during deviation; Just finely tune via the calibrator on the 3D signal projector 30 301, so that two signal Synchronization between first detection signal and second detection signal.Right mirror 62 adjustment modes are also identical with left mirror 61, and whether with second detection signal of right second inductor 71 synchronous, adjust via calibrator 301 again if analyzing first detection signals by waveform oscilloscope 80.With the left mirror 61 and right mirror 62 of said method adjustment shutter glasses 60, can reach the brightness maximum, the 3D image is the clearest and the perfect picture of ghost image does not take place.Be noted that at this calibrator 301 is a variable-resistance adjuster, can variable-resistance thus resistance matter change the starting time of adjusting 3D signal projector 30.
