Description

The method of shutter glasses and control shutter glasses
Technical field
The invention relates to the technology of watching stereo-picture, espespecially a kind of in order to the shutter glasses of watching the stereo-picture that video output device presents and the method for control shutter glasses.
Background technology
Along with the progress of science and technology, the no longer just high resolution image that the user pursues, but tool stereoscopic sensation and the more image demonstration of the sense of reality.The technology of at present stereo-picture demonstration mainly can be divided into two kinds, that is, a kind of video output device glasses (for example red blue glasses, polaroid glasses or shutter glasses) of arranging in pairs or groups in the lump that need use, and also a kind ofly then only need video output device and need not to arrange in pairs or groups any glasses.No matter be to adopt also a kind of technology, the cardinal principle that stereo-picture shows is exactly to allow left eye see respectively different picture frames from right eye, and then makes brain that two different picture frames of being seen respectively are considered as stereo-picture.
For shutter glasses, it is used at present the stereo-picture that allows the user watch video output device to present widely, shutter glasses can have two shutter eyeglasses, and open the suitable switching of closing with the shutter eyeglass and allow user's left eye to watch left-eye image and user's right eye to watch eye image via the shutter eyeglass, generally speaking, operate in the shutter glasses of the video output device of low picture update rate (for example 60Hz or 120Hz) for collocation, each shutter eyeglass is constantly to switch between opening and closed condition, for instance, when the shutter eyeglass of corresponding left eye when a certain specific time period is opened, the shutter eyeglass of corresponding right eye just can not opened, and when the shutter eyeglass of corresponding right eye when also a specific time period is opened, the shutter eyeglass of corresponding left eye just can not opened, yet, if the unlatching period of shutter eyeglass is suitably control not, then might see a part of left-eye image frame so that user's left eye is seen a part of eye image frame and/or user's right eye, thereby affect the quality of the stereo-picture that the user watches.
In addition, because each shutter glasses sector-meeting of shutter glasses is switched between opening and closed condition, the ambient brightness that therefore causes the user to experience can be less than the ambient brightness of reality; Also on the one hand, polarization direction based on the output of the image light of the video output device that is suitable for, the shutter glasses sector-meeting of the shutter glasses of arranging in pairs or groups has corresponding polarisation and sets, yet, the actual light that includes different angles of surround lighting, therefore, when the shutter eyeglass of shutter glasses is opened, the light that only has the polarisation that meets the shutter eyeglass to set can penetrate, therefore, also can so that the ambient brightness that the user experiences less than the ambient brightness of reality.When the ambient brightness of experiencing as the user who wears shutter glasses is not enough, the display screen that the user possibly can't know picks out video output device is with the object (for example keyboard or telepilot) of exterior domain, therefore, tend to cause the user in the inconvenience of watching on the stereo-picture.
Moreover, if being the control of using liquid crystal layer, the shutter eyeglass of shutter glasses carries out the switching of shutter opening and shutter close, generally speaking, when not applying any voltage and give liquid crystal layer, the shutter eyeglass is to be in opening and to allow light penetration, and as mentioned above, under known controlling mechanism, two shutter eyeglasses of shutter glasses are to open alternately, therefore, and when the liquid crystal layer of a shutter eyeglass does not apply voltage and allows light penetration in a certain period, also the liquid crystal layer of a shutter eyeglass just needs to apply voltage to block light penetration, therefore, longer if the shutter eyeglass is in the time of closed condition, then the power consumption of shutter glasses also increases thereupon.
In sum, how so that the user can obtain good picture quality when the stereo-picture of watching video output device to present, and watch under the stereo-picture not affecting the user, further promote the ambient brightness that the user that wears shutter glasses experiences and/or the power consumption that reduces shutter glasses and just become a technical field for this reason to need the problem of processing badly.

Embodiment
See also Fig. 1, Fig. 1 is the function block schematic diagram that the present invention is applied to watch the shutter glasses of the stereo-picture that video output device presents.In the present embodiment, shutter glasses 100 includes (but being not limited to) one first shutter eyeglass 102, one second shutter eyeglass 104 and a control circuit 106.First, second shutter eyeglass 102, one of 104 (for example the first shutter eyeglasses 102) are to watch left-eye image, and first, second shutter eyeglass 102,104 also one (for example the second shutter eyeglass 104) then are to watch eye image.In addition, control circuit 106 is exported respectively control signal S1, S2 to first, second shutter eyeglass 102,104, switches between opening and closed condition in switching between opening and the closed condition and controlling the second shutter eyeglass 104 to control the first shutter eyeglass 102.For instance, have respectively liquid crystal layer in first, second shutter eyeglass 102,104, therefore, control signal S1, S2 can be control voltage, are used for controlling the rotation of liquid crystal cells in the liquid crystal layer (LC cell) to reach the purpose of control light penetration rate.Right this only as the usefulness of example explanation, be not to be used as restriction of the present invention, any structure with the control of light penetration rate all can be used to realize first, second shutter eyeglass 102,104, can reach equally first, second shutter eyeglass 102 of control, 104 purposes of switching between opening and closed condition.
In the present invention, above-mentioned " closed condition " refers to first, the second shutter eyeglass 102,104 fully light tight (that is the light penetration rate is 0%), therefore, as long as first, the second shutter eyeglass 102,104 is not to be fully light tight (that is the light penetration rate is not to be 0%), just can be considered and be in " opening ", for instance, when first, the second shutter eyeglass 102,104 standard-sized sheets (for example the light penetration rate is 100%), half-open (for example the light penetration rate is 50%) or crack (for example the light penetration rate is 0.1%), first, the second shutter eyeglass 102,104 just can be considered and are in opening.In brief, when first, second shutter eyeglass 102,104 light penetration rate greater than 0% (but being less than or equal to 100%), then first, second shutter eyeglass 102,104 just is considered as entering opening.
Shutter glasses 100 is available for users to wear, with the stereo-picture of watching video output device 110 to be presented.For instance, video output device 110 can be a liquid crystal display, and it includes (but being not limited to) display screen (for example display panels) 112 and backlight module 114.Backlight module 114 provides display screen 112 required light sources, and just controls left eye or the right eye that whether can enter the user via shutter glasses 100 via the image light output that display screen 112 produces.Please note, it is liquid crystal display that video output device 110 does not limit, that is, video output device 110 can be any collocation in the lump with shutter glasses 100 and uses the video output device that gives the user to present stereo-picture, Organic Light Emitting Diode (Organic Light-Emitting Diode for example, OLED) display, plasma display panel, adopt digital light processing technology (Digital Light Processing, DLP) display/projector, adopt display/projector of liquid crystal on silicon (Liquid Crystal on Silicon, LCoS) display technique etc.
Shutter glasses 100 can be by wire transmission or wireless transmission (infrared transmission for example, the ZigBee transmission, ultra broadband (Ultrawideband, UWB) transmission, the WiFi transmission, radio frequency (Radio Frequency, RF) transmission, DLP optical signal transmission or bluetooth (Bluetooth) transmission) receives reference information SC from video output unit 110, for example, in shown in Figure 1, signal projector 120 is external in video output device 110, and be controlled by video output device 110 with the reference information SC that transmits video output device 110 and produced to shutter glasses 100, yet, in an embodiment also, signal projector 120 also can in be built in video output device 110.Thus, control circuit 106 just can produce control signal S1, S2 based on reference information SC.For instance, reference information SC can be the sequential of display screen 112 output map picture frames, and control circuit 106 can produce desired control signal S1, S2 voluntarily based on reference information SC, in other words, video output device 110 only provides synchronizing signal and first, second shutter eyeglass 102,104 control informations that when will open or close is not provided, and when will open or close but control first, second shutter eyeglass 102,104 by the synchronizing signal that control circuit 106 provides based on video output device 110 itself; In addition, reference information SC can also directly be first, second shutter eyeglass 102,104 control information (that is dominate first, second shutter eyeglass 102,104 by video output device 110 and when will open or close), and control circuit 106 just merely produces corresponding control signal S1, S2 based on the reference information SC that receives, please note, the above is only as the usefulness of example explanation, but not restriction of the present invention.
In one embodiment of the invention, video output device 110 is to operate in higher picture update rate (for example 200Hz, 240Hz, 400Hz or 480Hz), below just comes to provide further description for first, second shutter eyeglass 102,104 controlling mechanism with a plurality of examples.
See also Fig. 2, Fig. 2 is the sequential chart that is applied to the first control mode of shutter glasses shown in Figure 1.In this example, video output device 110 operates under the higher picture update rate (for example 240Hz), yet, video output device 110 also can operate under the higher picture update rate (for example 480Hz), at this moment, for same main picture frame, the demonstration output that operates under the higher picture update rate (for example 480Hz) can have more less important picture frame, but, no matter video output device 110 is to operate in the picture update rate of 240Hz or higher picture update rate (for example 480Hz), the control mode of shutter glasses is substantially the same, therefore for instructions for purpose of brevity, below only operate in 240Hz take video output device 110 picture update rate the control mode of shutter glasses 100 is described as example.As shown in Figure 2, video output device 110 can show one group of first picture frame ((L1 for example alternately, L1 '), (L2, and one group of second picture frame ((R1 for example L2 ')), R1 '), (R2, R2 ')), in addition, video output device 110 is respectively at ((T11 for example of continuous a plurality of the first picture frames output periods, T11 '), (T12, T12 ')) show one by one in that this organizes main first picture frame (for example L1 or L2) and less important first picture frame (for example L1 ' or L2 ') that the first picture frame is sequentially comprised, and respectively at ((T21 for example of continuous a plurality of the second picture frames output periods, T21 '), (T22, T22 ')) in show that one by one this organizes main second picture frame (for example R1 or R2) and less important second picture frame (for example R1 ' or R2 ') that the second picture frame is sequentially comprised.Note that and this organize the first picture frame and this to organize one of second picture frame be to be one group of left-eye image frame, and this group first picture frame and this organize the second picture frame one is to be one group of eye image frame also.In other words, in an embodiment, the first picture frame L1, L1 ', L2, L2 ' represent the left-eye image frame, and the second picture frame R1, R1 ', R2, R2 ' represent the eye image frame, yet, in an embodiment also, the first picture frame L1, L1 ', L2, L2 ' represent the eye image frame, and the second picture frame R1, R1 ', R2, R2 ' represent the left-eye image frame.
Similarly, for video output device 110 operated in higher picture update rate (for example 480Hz), video output device 110 also can show one group of first picture frame and one group of second picture frame alternately, for example, in an implementation mode, the display order of picture frame is: L1, L1 ', R1, R1 ', L2, L2 ', R2, R2 ', wherein L1 and L2 are main the first picture frame, L1 ' and L2 " be less important the first picture frame; R1 and R2 are main the second picture frame, R1 ' and R2 " be less important the second picture frame, therefore (L1, L1 ') with (L2, L2 ') consist of respectively one group of first picture frame, and (R1, R1 ') and (R2, R2 ') consists of respectively one group of second picture frame, in addition, in this embodiment, less important first, the number of the second picture frame is only as the usefulness of example explanation; And in the implementation mode of going back, the display order of picture frame then is L1, L1 ', L1 ", L1 " ', R1, R1 ', R1 ", R1 " ', wherein L1 is main the first picture frame, L1 ', L1 "; L1 " ' be less important the first picture frame, R1 is main the second picture frame, R1 ', R1 "; R1 " ' be less important the second picture frame, therefore (L1, L1 ', L1 "; L1 " ') one group of first picture frame of formation, and (R1, R1 ', R1 "; R1 " ') one group of second picture frame of formation, in addition, in this embodiment, less important first, the number of the second picture frame is only as the usefulness of example explanation.Note that on implementation, backlight module 114 can give less important the first picture frame L1 ', L1 ", L1 " ' with less important the second picture frame R1 ', R1 ", R1 " ' brighter backlight, yet this is only as the usefulness of example explanation, but not restriction of the present invention.In addition, when video output device 110 (for example liquid crystal display, organic light emitting diode display, plasma display panel or display/projector of adopting other display technique) operates in higher picture update rate (for example 240Hz or more than the 240Hz), for same group of the first/the second picture frame, the time span summation of all less important the first/the second picture frames can be more than or equal to the time span of main the first/the second picture frame.
In an embodiment, less important the first picture frame is for showing again main the first picture frame that is arranged in same group of the first picture frame, and less important the second picture frame is for showing again main the second picture frame that is arranged in same group of the second picture frame, (for example the first picture frame is exported period T11 and is included image-driven time T P1 and image stabilization time T H1 although each first picture frame output period and each the second picture frame output period have included an image-driven time and an image stabilization time, picture frame output period T11 ' includes image-driven time T P1 ' and image stabilization time T H1 ', by that analogy.Please note, based on the display technique that adopts, each image stabilization time can include non-image driving time or image is held time, for instance, transmitted the image-driven signal in time or do not transmitted the image-driven signal in the time in image stabilization in image-driven, therefore can be considered at this moment, picture frame is in steady state (SS), for example, for pixel (liquid crystal cells or Organic Light Emitting Diode unit), when image-driven had transmitted the image-driven signal and so that arbitrary pixel itself has reached the stable time lights and can be considered as entering the image stabilization time in the time, also on the one hand, from do not transmit the image-driven signal light also to can be considered to the time of arbitrary pixel enter the image stabilization time).For liquid crystal display, need the rotation of control liquid crystal cells to reach the purpose of control light penetration rate, under lower picture update rate (for example 60Hz or 120Hz), consider the required rotation time of liquid crystal cells, mainly be to utilize the image stabilization time be right after after the image-driven time to carry out presenting of stereo-picture, yet, under higher picture update rate (for example 240Hz or 480Hz), the length of each image stabilization time can be shorter, but within the identical time, the liquid crystal display that operates under the higher picture update rate can be exported more picture frame, therefore, just can utilize the corresponding picture frame output period of less important picture frame to provide stablizes picture and opens first, the second shutter eyeglass 102,104 to allow the user carry out watching of stereo-picture.In simple terms, can be responsible for upgrading the previous before content (that is content of last main picture frame) of a picture frame that shown by each main picture frame (routine L1 described above, L2, R1 or R2), therefore, the main picture frame that present wish shows replace fully before shown before before the picture frame, the Output rusults of the corresponding image-driven of main picture frame in the time that display screen 112 (for example display panels) shows in present wish can comprise a part of at present main picture frame and a part of last main picture frame; Also on the one hand, follow-up less important picture frame (routine L1 ' described above, L2 ', R1 ', R2 ', L1 '～L1 " ' or R1 '～R1 " ') then is responsible for stablizing picture and is carried out watching of stereo-picture for the user by shutter glasses 100.
In addition, in going back an embodiment, less important the first picture frame is the lasting Output rusults for main the first picture frame itself in same group of the first picture frame, that is, in the corresponding image-driven of main picture frame in the time, display screen 112 can be according to showing data from top to bottom line by line by end with the leftmost side to the rightmost side of delegation set each pixel with the main picture frame exporting present wish and show (in other implementation mode, based on the modes of emplacement of display panels or the difference of design, also can be from bottom to top sequentially set each pixel (for example display panels is divided into a plurality of viewing areas with the export present wish present picture frame that shows or the pixel update sequence that adopts other by ending with the rightmost side to the leftmost side of delegation line by line, and there is the pixel update sequence of oneself each viewing area)), yet, in the follow-up corresponding image-driven of less important picture frame among the time, display screen 112 does not carry out the display driver operation based on any demonstration data, therefore based on the characteristic of display panels, display screen 112 still can continue to demonstrate the content of main picture frame, can reach the effect of stablizing picture equally.Moreover, less important the first picture frame can also be entirely to deceive picture or finely tune the picture that (for example affording redress for the interference between the picture frame (crosstalk)) produces based on main the first picture frame in same group of the first picture frame, can reach the effect of stablizing picture equally.
In addition, in more also in the embodiment, main the first/the second picture frame can also be entirely to deceive picture, and backlight module 114 can be opened in the output period at the corresponding picture frame of less important the first/the second picture frame and carries out watching of stereo-picture for the user.
Control circuit 106 can switch between opening (" ON ") and closed condition (" OFF ") by control the first shutter eyeglass 102, and control the second shutter eyeglass 104 and between opening (" ON ") and closed condition (" OFF "), switch, and in this example, control circuit 106 controls the first shutter eyeglass 102 can be in opening among corresponding the first picture frame output of specific less important the first picture frame (for example L1 ' or L2 ') period (for example T11 ' or T12 '), and among corresponding the second picture frame output of specific main the second picture frame that is right after specific less important the first picture frame (for example R1 or R2) period (for example T21 or T22), can be in closed condition, as shown in Figure 2, in the present embodiment, the first shutter eyeglass 102 can switch to opening by closed condition in the starting point of corresponding the first picture frame output period of specific less important the first picture frame, and switch to closed condition in the end point of corresponding the first picture frame of specific less important the first picture frame output period by opening, afterwards, between the starting point of corresponding the second picture frame of follow-up specific main the second picture frame output period and end point, keep closed condition.Also on the one hand, control circuit 106 is also controlled the second shutter eyeglass 104 can be in closed condition among corresponding the second picture frame output of specific main the second picture frame (for example R1 or R2) period (for example T21 or T22), and among corresponding the second picture frame output of specific less important the second picture frame that is right after specific main the second picture frame (for example R1 ' or R2 ') period (for example T21 ' or T22 '), can be in opening, as shown in Figure 2, in the present embodiment, the second shutter eyeglass 102 can be kept closed condition between the starting point of corresponding the second picture frame of specific main the second picture frame output period and end point, and switch to opening in the starting point of corresponding the second picture frame of follow-up specific less important the second picture frame output period by closed condition, and switch to closed condition in the end point of corresponding the second picture frame output period of specific less important the second picture frame by opening.In addition, as shown in the figure, first, second shutter eyeglass 102,104 only can be in closed condition simultaneously in a single continuous time (for example P1 or P2) among corresponding the second picture frame output of specific main the second picture frame (for example R1 or R2) period (for example T21 or T22).
Please note, Fig. 2 only demonstrates control circuit 106 control first in one period running time (for example picture frame output period T11～T22 '), the second shutter eyeglass 102,104 operation, and in fact, control circuit 106 still can be constantly in previous running time (for example picture frame output period before the picture frame output period T11) and follow-up running time (for example picture frame output period T22 ' picture frame output period afterwards) repeats same controlling mechanism and controls first based on identical glasses cycle (that is left eye and right eye respectively see a picture frame cycle) or different glasses cycles, the second shutter eyeglass 102,104 switchings between opening and closed condition.Operation for mixing the different glasses cycle sees also Fig. 2 and Fig. 3, and Fig. 3 is that operation shown in Figure 2 is based on corresponding continuity sequential chart under the concept of mixing the different glasses cycle.As shown in Figure 3, the glasses cycle originally equals the picture frame output period (for example T11+T11 '+T21+T21 ') of four picture frames, yet, after the second picture frame output period T21 ' finishes, it is the picture frame output period (for example T12+T12 '+T22+T22 '+T13+T13 '+T23+T23 ') of eight picture frames that the glasses cycle just increases, therefore in this example, the first shutter glasses 102 follow-up starting points in corresponding the first picture frame output of less important the first picture frame L4 ' period T14 ' just switch to opening by closed condition, and the second shutter glasses 104 follow-up starting points in corresponding the second picture frame output of less important the second picture frame R4 ' period T24 ' just switch to opening by closed condition.Please note, be used as glasses cycle also only as the usefulness of example explanation with the picture frame of eight picture frames output period, but not restriction of the present invention, in fact, the number of corresponding picture frame output period in glasses cycle can be adjusted according to the demand on using.In addition, in the above-mentioned mixing example in different glasses cycles, to repeat same controlling mechanism in the cycle in going back long glasses, yet, in these long glasses in the cycle, other the controlling mechanism of also can additionally mixing, and the shutter eyeglass is not carried out in the period (for example T13～T23 ') of any On/Off control in controlling mechanism originally, control the On/Off of shutter eyeglass by other controlling mechanism, the variation in this design is spirit according to the invention also.
As previously mentioned, the main picture frame that present wish shows replace fully before shown before before the picture frame, the Output rusults of the corresponding image-driven of main picture frame in the time that display screen 112 (for example display panels) shows in present wish can comprise a part of at present main picture frame and a part of last main picture frame, therefore, enter user's eyes for fear of the rubbish image, in this example, except controlling first, the second shutter eyeglass 102, outside 104, backlight module 114 only can be in less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', open among the TP4 ' (" ON "), in other words, backlight module 114 can be in main first, the second picture frame is distinguished corresponding image-driven time T P1, TP2, TP3, close (" OFF ") among the TP4.Therefore, in this example, backlight module 114 only just can be in opening when first, second shutter eyeglass 102,104 is in opening, backlight to close the period be at least part of overlapping therefore above-mentioned single continuous time (for example P1 or P2) and backlight module 114 are in closed condition.Generally speaking, by first, second shutter eyeglass 102,104 and the suitable control of backlight module 114, can be so that the user can obtain good picture quality when the stereo-picture of watching video output device 110 to present.
Please note, in the implementation mode of going back, backlight module 114 is except less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', outside being held open among the TP4 ', the backlight open period of backlight module 114 also can be from less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', the starting point of TP4 ' is a little expansion (shown in dotted portion among the figure) forward, and/or from less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', the end point of TP4 ' is a little expansion (shown in dotted portion among the figure) backward, take less important the first picture frame L1 ' as example, in the first embodiment, the backlight open period of backlight module 114 only includes image-driven time T P1 ', in the second embodiment, the backlight open period of backlight module 114 includes image-driven time T P1 ' and image stabilization time T H1 ', and in the 3rd embodiment, the backlight open period of backlight module 114 includes image-driven time T P1 ' and image stabilization time T H1 and TH1 ', in other words, backlight module 114 can just switch to opening by closed condition before the starting point of less important the first/the second picture frame corresponding image-driven time, and/or switched back closed condition by opening again after the end point of less important the first/the second picture frame corresponding image-driven time.According to above-mentioned, the backlight open period that backlight module 114 is in opening can be contained and greater than less important the first/the second picture frame corresponding image-driven time, wherein backlight module 114 can be in opening in the corresponding image-driven of less important the first/the second picture frame in the time, and can be in closed condition in adjacent image stabilization in the time, and backlight module 114 is in closed condition in this adjacent image stabilization in the time time span is the time span that is less than or equal to this adjacent image stabilization time.
As mentioned above, the first shutter eyeglass 102 switches to opening in the starting point of corresponding the first picture frame output period of specific less important the first picture frame by closed condition, and switch to closed condition in the end point of this first picture frame output period by opening, and the starting point of the second shutter eyeglass 102 in corresponding the second picture frame output period of specific less important the second picture frame switches to opening by closed condition, and switching to closed condition in the end point of this second picture frame output period by opening, right the present invention is not as limit.See also Fig. 4, Fig. 4 is the sequential chart that is applied to the second control mode of shutter glasses shown in Figure 1.In this example, the first shutter eyeglass 102 just switched to opening by closed condition before the starting point of corresponding the first picture frame output of specific less important the first picture frame (for example L1 ' or L2 ') period (for example T11 ' or T12 '), and after the end point of corresponding the first picture frame output of specific less important the first picture frame (for example L1 ' or L2 ') period (for example T11 ' or T12 '), just switch to closed condition by opening, and second shutter eyeglass 102 before the starting point of corresponding the second picture frame of specific less important the second picture frame (for example R1 ' or R2 ') output period (for example T21 ' or T22 '), just switch to opening by closed condition, and after the end point of corresponding the second picture frame output of specific less important the second picture frame (for example R1 ' or R2 ') period (for example T21 ' or T22 '), just switch to closed condition by opening.Please note, example as shown in Figure 2, first, second shutter eyeglass 102,104 only can be in closed condition simultaneously in a single continuous time (for example P1 or P2) among corresponding the second picture frame output of specific main the second picture frame (for example R1 or R2) period (for example T21 or T22).In addition above-mentioned single continuous time (for example P1 or P2) and backlight module 114 be in closed condition backlight to close the period be at least part of overlapping (in this example, the single continuous time that first, second shutter eyeglass 102,104 is in opening simultaneously can fall within the backlight of backlight module 114 fully and close among the period).
Similarly, in order effectively to avoid the rubbish image to enter user's eyes, in this example, except controlling first, second shutter eyeglass 102,104, backlight module 114 only can be distinguished unlatching (" ON ") among corresponding image-driven time T P1 ', TP2 ', TP3 ', the TP4 ' in less important first, second picture frame, therefore by first, second shutter eyeglass 102,104 and the suitable control of backlight module 114, just can be so that the user can obtain good picture quality when the stereo-picture of watching video output device 110 to present.In addition, backlight module 114 can be closed (" OFF ") in main first, second picture frame be distinguished the image-driven time T P1 ', TP2 ', TP3 ', TP4 ' of correspondence, owing to lacking required backlight, the demonstration output of display screen 112 in picture frame output period T11, T21, T12, T22 can't be seen by user's eyes, although first, second shutter eyeglass 102,104 is opened in picture frame output period T11, T21, T12, T22, does not affect watching of stereo-picture.Yet, because first, second shutter eyeglass 102, opening time of 104 increase, therefore, compared to example shown in Figure 2, can promote the ambient brightness that the user experiences; In addition, because first, second shutter eyeglass 102, opening time of 104 be increased, the just corresponding minimizing of first, second shutter eyeglass 102, shut-in time of 104 is therefore also can reduce the power consumption of shutter glasses 100.
In addition, in the implementation mode of going back, backlight module 114 is except in less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', outside being held open among the TP4 ', the backlight open period of backlight module 114 also can be from less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', the starting point of TP4 ' is a little expansion forward, and/or from less important first, the second picture frame is distinguished corresponding image-driven time T P1 ', TP2 ', TP3 ', the end point of TP4 ' is a little expansion backward, and the variation in these designs all belongs to category of the present invention.
In addition, the content of relevant backlight module 114 only is the controlling mechanism in order to aid illustration shutter glasses 100 of the present invention, that is, no matter the design of the backlight open period of backlight module 114 why, as long as the open and close spirit according to the invention of the first shutter eyeglass 102 and the second shutter eyeglass 104 all can allow the user carry out watching of stereo-picture and fall into category of the present invention in the shutter glasses 100.
Please note, shown in Figure 4 only as the usefulness of example explanation, but not restriction of the present invention, that is under the prerequisite of spirit of the present invention, other design variation based on example shown in Figure 4 also is feasible, in other words, first, second shutter eyeglass 102,104 shutter opening period of being in opening might not be extended forward in the lump and be extended backward.For instance, plant one or the wherein combination of a plurality of operations of operation as long as comprise following plural number: the first shutter eyeglass 102 switched to opening by closed condition before the starting point of specific less important the first picture frame corresponding image-driven time, the first shutter eyeglass 102 just switches to closed condition by opening after the end point of specific less important the first picture frame corresponding image-driven time, the second shutter eyeglass 104 switched to opening by closed condition before the starting point of specific less important the second picture frame corresponding image-driven time, and second shutter eyeglass 104 after the end point of specific less important the second picture frame corresponding image-driven time, switch to closed condition by opening, all meet the present invention and promote the design spirit of ambient brightness and fall into category of the present invention.
In above-mentioned example, backlight module 114 can be realized by a type backlight module, that is, when backlight module 114 is opened, all pixels all can receive backlight that backlight module 114 gives in the display screen 112, yet the present invention is not as limit, and backlight module 114 also can be realized by one scan formula (scanning) backlight module.See also Fig. 4, Fig. 4 is the operation chart of scanning backlight module.All pixels can be divided into a plurality of viewing areas in the display screen 112, and the scanning backlight module gives extremely these a plurality of viewing areas backlight in turn, therefore, can be by cover smear image that display screen (for example display panels) 112 causes and the interference between the picture frame without viewing area backlight.As shown in Figure 5, display screen 112 from top to bottom is divided into a plurality of viewing areas (for example four viewing area 402,404,406,408), therefore, be among the backlight open period TL of opening in the scanning backlight module, viewing area 402,404,406,408 can give (shown in the blank block of Fig. 5) backlight seriatim.Compared to face type backlight module, the time that the scanning backlight module is opened might (for example be grown, surpass less important the first/the second picture frame time span of corresponding the first/the second picture frame output period, and near (less than) time span of corresponding the first/the second picture frame output period of less important the first/the second picture frame and the summation of the time span of corresponding the second/the first picture frame output period of main the second/the first picture frame that is right after), yet the present invention is not as limit.
When collocation scanning backlight module, control circuit 106 must suitably be adjusted in response to the scanning backlight module is in the backlight open period of opening for first, second shutter eyeglass 102,104 control mode.See also Fig. 6, Fig. 6 is the sequential chart that is applied to the third control mode of shutter glasses shown in Figure 1.In this example, backlight module 114 is to be the scanning backlight module.As shown in the figure, backlight module 114 is opened except distinguish corresponding picture frame output period T11 ', T21 ', T12 ', T22 ' at less important first, second picture frame in, in addition in follow-up main first, second picture frame institute respectively the picture frame of correspondence export among period T21, T12, the T22 and open a period of time.Please note, although backlight module 114 can be main first, the second picture frame is distinguished corresponding picture frame output period T21, T12, open a period of time among the T22, yet, as shown in Figure 5, when main first, the second picture frame is in picture frame output period T21, T12, T22 upgrade pixel data line by line for the previous period from top to bottom the time, the upper half area of display screen 112 does not give backlight, therefore, in fact the user can't see the pixel data after the renewal, in other words, although before the main picture frame of at present wish demonstration replaces the previous image frame that has before shown fully, the Output rusults of the corresponding image-driven of main picture frame in the time that display screen 112 (for example display panels) shows in present wish can comprise a part of at present main picture frame and a part of last main picture frame, yet, suitably gated sweep formula backlight module and first, under the second shutter eyeglass, the rubbish image can't enter user's eyes, thereby still can allow the user can obtain good picture quality when the stereo-picture of watching video output device to present.
In this example, backlight module 114 only just can be in opening when first, second shutter eyeglass 102,104 is in opening, in addition, first, second shutter eyeglass 102,104 only can be in closed condition simultaneously in a single continuous time (for example P1 or P2) among corresponding the second picture frame output of specific main the second picture frame (for example R1 or R2) period (for example T21 or T22).
Please note, in the implementation mode of going back, backlight module 114 is except less important first, the second picture frame is distinguished corresponding picture frame output period T11 ', T21 ', T12 ', open among the T22 ', and follow-up main first, the second picture frame is distinguished corresponding picture frame output period T21, T12, open outside a period of time among the T22, the backlight open period of backlight module 114 also can be from less important first, the second picture frame is distinguished corresponding picture frame output period T11 ', T21 ', T12 ', T22 ' (that is image-driven time T P1 ', TP2 ', TP3 ', TP4 ') starting point is a little expansion forward, in other words, backlight module 114 can be in less important first, the second picture frame is distinguished corresponding picture frame output period T11 ', T21 ', T12 ', T22 ' (that is image-driven time T P1 ', TP2 ', TP3 ', TP4 ') just switches to opening by closed condition before the starting point.
In addition, Fig. 6 only demonstrates control circuit 106 control first in one period running time (for example picture frame output period T11～T22 '), the second shutter eyeglass 102,104 operation, and in fact, control circuit 106 still can be constantly in previous running time (for example picture frame output period before the picture frame output period T11) and follow-up running time (for example picture frame output period T22 ' picture frame output period afterwards) repeats same controlling mechanism and controls first based on identical glasses cycle (that is left eye and right eye respectively see a picture frame cycle) or different glasses cycles, the second shutter eyeglass 102,104 switchings between opening and closed condition.Operation for mixing the different glasses cycle sees also Fig. 6 and Fig. 7, and Fig. 7 is that operation shown in Figure 6 is based on corresponding continuity sequential chart under the concept of mixing the different glasses cycle.As shown in Figure 6, the glasses cycle originally equals the picture frame output period (for example T11+T11 '+T21+T21 ') of four picture frames, yet, after the second picture frame output period T21 ' finishes, it is the picture frame output period (for example T12+T12 '+T22+T22 '+T13+T13 '+T23+T23 ') of eight picture frames that the glasses cycle just increases, therefore in this example, the first shutter glasses 102 follow-up starting points in corresponding the first picture frame output of less important the first picture frame L4 ' period T14 ' just switch to opening by closed condition, and the second shutter glasses 104 follow-up starting points in corresponding the second picture frame output of less important the second picture frame R4 ' period T24 ' just switch to opening by closed condition.Please note, be used as glasses cycle also only as the usefulness of example explanation with the picture frame of eight picture frames output period, but not restriction of the present invention, in fact, the number of corresponding picture frame output period in glasses cycle can be adjusted according to the demand on using.In addition, in the above-mentioned mixing example in different glasses cycles, to repeat same controlling mechanism in the cycle in going back long glasses, yet, in these long glasses in the cycle, other the controlling mechanism of also can additionally mixing, and the shutter eyeglass is not carried out in the period (for example T13～T23 ') of any On/Off control in controlling mechanism originally, control the On/Off of shutter eyeglass by other controlling mechanism, the variation in this design is spirit according to the invention also.
As shown in Figure 6, the first shutter eyeglass 102 switches to opening in the starting point of corresponding the first picture frame output period of specific less important the first picture frame by closed condition, and switch to closed condition in the rear ability of the end point of corresponding the first picture frame of specific less important the first picture frame output period by opening, and the second shutter eyeglass 104 just switched to opening by closed condition before specific less important the second picture frame starting point of corresponding the second picture frame output period, and switch to closed condition in the end point of corresponding the second picture frame of specific less important the second picture frame output period by opening, yet, the present invention is not as limit, that is, example as shown in Figure 4, in the example shown in Figure 6 first, the second shutter eyeglass 102, the 104 shutter opening periods that are in opening can be extended forward and/or be extended backward, to promote the ambient brightness that the user was experienced and to reduce the power consumption of shutter glasses 100.See also Fig. 8, Fig. 8 is the sequential chart that is applied to the 4th kind of control mode of shutter glasses shown in Figure 1.Similarly, example as shown in Figure 6, first, the second shutter eyeglass 102,104 only can be in closed condition simultaneously in a single continuous time (for example P1 or P2) among corresponding the second picture frame output of specific main the second picture frame (for example R1 or R2) period (for example T21 or T22), in addition, above-mentioned single continuous time (for example P1 or P2) and backlight module 114 are in closed condition backlight close the period be at least part of overlapping (in this example, first, the second shutter eyeglass 102, the 104 single continuous times that are in simultaneously opening can fall within the backlight of backlight module 114 fully and close among the period).Please note, shown in Figure 6 only as the usefulness of example explanation, but not restriction of the present invention, that is under the prerequisite of spirit of the present invention, other design variation based on example shown in Figure 6 also is feasible, for instance, the shutter opening period that first, second shutter eyeglass 102,104 is in opening might not be extended forward in the lump and be extended backward, and the variations in these designs all belong to category of the present invention.
In addition, less important first, the second picture frame is distinguished (the image-driven time T P1 ' for example of corresponding picture frame in the output period, TP2 ', TP3 ', TP4 '), mainly be that unlatching by backlight module 114 allows the user to see picture frame, and in shutter opening in the period, liquid crystal cells in the liquid crystal layer of the first shutter glasses 102/ second shutter eyeglass 104 just rotates so that the first shutter eyeglass 102/ second shutter eyeglass 104 switches to opening by closed condition before in the corresponding picture frame of less important the first picture frame/less important the second picture frame output period (for example image-driven time), and just rotate afterwards so that the first shutter eyeglass 102/ second shutter eyeglass 104 switches to closed condition by opening in the corresponding picture frame of less important the first picture frame/less important the second picture frame output period (for example image-driven time), then work as the user in less important first, the second picture frame is distinguished when watching picture frame in corresponding picture frame output period (for example image-driven time), and the present invention also can reduce liquid crystal cells in the rotational response brightness decay that (that is in rotation process) causes in the time.
According to Fig. 6 and example shown in Figure 8, shutter eyeglass controlling mechanism of the present invention can be applicable to video output device 110 and operates in higher picture update rate (for example 240Hz or 480Hz) and adopt under the scanning backlight module, yet shutter eyeglass controlling mechanism of the present invention also can be applicable to video output device 110 and operates in low picture update rate (for example 60Hz, 96Hz, 100Hz, 110Hz or 120Hz) and adopt under the scanning backlight module.See also Fig. 9, Fig. 9 is the sequential chart that is applied to the 5th kind of control mode of shutter glasses shown in Figure 1.In this example, backlight module 114 is to be the scanning backlight module, and video output device 110 operates under the low picture update rate (for example 60Hz or 120Hz), as shown in Figure 9, video output device 110 (for example shows one first picture frame (L1 for example alternately in a plurality of picture frames output periods respectively among the T1～T7), L2, L3 or L4) and one second picture frame (R1 for example, R2 or R3), wherein first, one of second picture frame is to be a left-eye image frame, and first, the second picture frame one be to be an eye image frame also.In other words, in an embodiment, the first picture frame L1, L2, L3, L4 represent the left-eye image frame, and the second picture frame R1, R2, R3 represent the eye image frame; In going back an embodiment, the first picture frame L1, L2, L3, L4 represent the eye image frame, and the second picture frame R1, R2, R3 represent the left-eye image frame.In addition, as shown in the figure, each picture frame output period includes an image-driven time and an image stabilization time (note that each image stabilization time can include non-image driving time or image is held time based on the display technique of the actual employing of institute).For instance, picture frame output period T1 includes image-driven time T P1 and image stabilization time T H1, and picture frame output period T2 includes image-driven time T P1 ' and image stabilization time T H1 ', by that analogy.In each image-driven in the time, display screen 112 (for example display panels) can be according to showing data from top to bottom line by line by end with the leftmost side to the rightmost side of delegation sequentially set each pixel with the present picture frame exporting present wish and show (in other implementation mode, based on the modes of emplacement of display panels or the difference of design, also can be from bottom to top sequentially set each pixel (for example display panels is divided into a plurality of viewing areas with the export present wish present picture frame that shows or the pixel update sequence that adopts other by ending with the rightmost side to the leftmost side of delegation line by line, and there is the pixel update sequence of oneself each viewing area)), that is, display screen 112 can replace with the present picture frame that present wish shows the previous image frame that has before shown, therefore, the present picture frame that present wish shows replace fully before shown before before the picture frame, display screen 112 can comprise a part of present picture frame and a part of previous image frame in the Output rusults of image-driven in the time; Also on the one hand, in follow-up image stabilization in the time, display screen 112 can wait for that the present picture frame that wish shows reaches stable, for example display screen 112 can not drive pixel based on any demonstration data, that is, the above-mentioned image stabilization time can be a vertical blanking interval (vertical blanking interval, VBI).
Control circuit 106 can switch between opening (" ON ") and closed condition (" OFF ") by control the first shutter eyeglass 102, and control the second shutter eyeglass 104 and between opening (" ON ") and closed condition (" OFF "), switch, and in this example, control circuit 106 control the first shutter eyeglass 102 is in specific the first picture frame (L1 for example, L2 or L3) (TH1 for example of corresponding image stabilization time, TH2 or TH3) among can be in opening, and in specific the second picture frame that is right after specific the first picture frame (R1 for example, R2 or R3) (TP1 ' for example of corresponding image-driven time, TP2 ' or TP3 ') among can be in closed condition, as shown in Figure 9, in the present embodiment, the starting point of the first shutter eyeglass 102 in the image stabilization time switches to opening by closed condition, and just can switch to closed condition by opening after the end point of this image stabilization time.Also on the one hand, control circuit 106 controls the second shutter eyeglass 104 can be in closed condition among specific the second picture frame (for example R1, R2 or R3) corresponding image-driven time (for example TP1 ', TP2 ' or TP3 '), and can be in opening among same specific the second picture frame (for example R1, R2 or R3) corresponding image stabilization time (for example TH1 ', TH2 ' or TH3 '); The second shutter eyeglass 104 is in closed condition in image-driven in the time, and switches to opening in the starting point of the image stabilization time that is right after by closed condition, until just can switch to closed condition by opening after the end point of this image stabilization time.First, second shutter eyeglass 102,104 is in only being in simultaneously closed condition in a single continuous time (for example P1 or P2) among specific the second picture frame (for example R1 or R2) corresponding image-driven time (for example TP1 ' or TP2 '), in addition above-mentioned single continuous time (for example P1 or P2) and backlight module 114 be in closed condition backlight to close the period be at least part of overlapping (in this example, both overlap fully).
Please note, Fig. 9 only demonstrates control circuit 106 and (for example controls first among the picture frame output period T1～T6) in one period running time, the second shutter eyeglass 102,104 operation, and in fact, control circuit 106 still can be constantly in previous running time (for example picture frame output period before the picture frame output period T1) and follow-up running time (for example the picture frame after the picture frame output period T6 is exported the period) repeats same controlling mechanism and controls first based on identical glasses cycle (that is left eye and right eye respectively see a picture frame cycle) or different glasses cycles, the second shutter eyeglass 102,104 switchings between opening and closed condition.Operation for mixing the different glasses cycle sees also Fig. 9 and Figure 10, and Figure 10 is that operation shown in Figure 9 is based on corresponding continuity sequential chart under the concept of mixing the different glasses cycle.As shown in Figure 9, the glasses cycle originally equals the picture frame output period (for example T1+T2 or T3+T4) of two picture frames, and after image stabilization time T H2 ' finishes, it is the picture frame output period (for example T5+T6+T7+T8 or T9+T10+T11+T12) of four picture frames that the glasses cycle just increases, therefore in this example, the first shutter glasses 102 follow-up starting points in the corresponding image stabilization time T of the first picture frame L5 H5 just switch to opening by closed condition, and the second shutter glasses 104 follow-up starting points in the corresponding image stabilization time T of the second picture frame R5 H5 ' just switch to opening by closed condition.Please note, be used as glasses cycle also only as the usefulness of example explanation with the picture frame of four picture frames output period, but not restriction of the present invention, in fact, the number of corresponding picture frame output period in glasses cycle can be adjusted according to the demand on using.In addition, in the above-mentioned mixing example in different glasses cycles, to repeat same controlling mechanism in the cycle in going back long glasses, yet, in these long glasses in the cycle, other the controlling mechanism of also can additionally mixing, and the shutter eyeglass is not carried out the period of any On/Off control (for example among the T7～T8) in controlling mechanism originally, control the On/Off of shutter eyeglass by other controlling mechanism, the variation in this design is spirit according to the invention also.
As previously mentioned, the picture frame that present wish shows replace fully before shown before before the picture frame, the Output rusults of display screen 112 (for example display panels) in the corresponding image-driven of the picture frame time that present wish shows can comprise a part of present picture frame and a part of previous image frame, therefore, enter user's eyes for fear of the rubbish image, in this example, backlight module 114 only can be in first, the second shutter eyeglass 102,104 just can be in opening when being in opening, please note, although backlight module 114 is in first, the second picture frame is distinguished corresponding image-driven time T P1～TP3, can open a period of time among TP1 '～TP3 ', yet, as shown in Figure 5, when first, the second picture frame is in image-driven time T P1～TP3, TP1 '～TP3 ' upgrade pixel data line by line for the previous period from top to bottom the time, the upper half area of display screen 112 does not give backlight, therefore, in fact the user can't see the pixel data that has upgraded, in other words, suitably gated sweep formula backlight module and first, under the second shutter eyeglass, the rubbish image can't enter user's eyes, thereby so that the user can obtain good picture quality when the stereo-picture of watching video output device to present.
Please note, in the implementation mode of going back, backlight module 114 is except in image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, be held open among the TH3 ' and from image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, a period of time is just switched to outside the closed condition by opening after the end point of TH3 ', the backlight open period of backlight module 114 also can be from image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, the starting point of TH3 ' is a little expansion forward, in other words, backlight module 114 can just switch to opening by closed condition before the starting point of image stabilization time.In brief, the backlight open period of backlight module 114 can be expanded forward and/or expand backward from the end point of image stabilization time from the starting point of image stabilization time, and the extension time span of the forward/backward of backlight open period expansion can be decided according to demand, that is, by the controlling mechanism that suitable collocation shutter glasses 100 adopts, backlight module 114 can continue to open or periodically open and close fully without interruption.
As shown in Figure 9, the first shutter eyeglass 102 switches to opening in the starting point of specific the first picture frame corresponding image stabilization time by closed condition, and after the end point of this image stabilization time, just switch to closed condition by opening, and the starting point of the second shutter eyeglass 102 in specific the second picture frame corresponding image stabilization time switches to opening by closed condition, and after the end point of this image stabilization time, switch to closed condition by opening, yet, the present invention is not as limit, that is, example as shown in Figure 4, in the example shown in Figure 9 first, the second shutter eyeglass 102, the 104 shutter opening periods that are in opening also can be extended forward and/or be extended backward, with the further power consumption that promotes the ambient brightness that the user was experienced and reduce shutter glasses 100.See also Figure 11, Figure 11 is the sequential chart that is applied to the 6th kind of control mode of shutter glasses shown in Figure 1.Similarly, example as shown in Figure 9, first, the second shutter eyeglass 102,104 in specific the second picture frame (R1 for example, R2 or R3) (TP1 ' for example of corresponding image-driven time, TP2 ' or TP3 ') among only can be in a single continuous time (P1 for example, P2 or P3) in be in simultaneously closed condition, in addition, above-mentioned single continuous time (P1 for example, P2 or P3) with backlight module 114 be in closed condition backlight close the period be at least part of overlapping (in this example, first, the second shutter eyeglass 102, the 104 single continuous times that are in simultaneously opening can fall within the backlight of backlight module 114 fully and close among the period).
Please note, as above-mentioned explanation for example shown in Figure 4, shown in Figure 11 only as the usefulness of example explanation, but not restriction of the present invention, that is under the prerequisite of spirit of the present invention, other design variation based on example shown in Figure 9 also is feasible, in other words, first, the second shutter eyeglass 102, the 104 shutter opening periods that are in opening might not be extended forward in the lump and be extended backward, and the variation in these designs all belongs to category of the present invention, in addition, owing to skilled persons will can be easily understood other design variation based on example shown in Figure 9 according to previous explanation, therefore just do not give unnecessary details in addition in this.
In above-mentioned example, at image stabilization time (TH1 for example, TH1 ', TH2, TH2 ', TH3, TH3 ') among, mainly be that unlatching by backlight module 114 allows the user to see picture frame, and in shutter opening in the period, liquid crystal cells in the liquid crystal layer of the first shutter eyeglass 102/ second shutter eyeglass 104 just rotated before the image stabilization time so that the first shutter eyeglass 102/ second shutter eyeglass 104 switches to opening by closed condition, and just rotate after the time so that the first shutter eyeglass 102/ second shutter eyeglass 104 switches to closed condition by opening in image stabilization, then when the user when image stabilization is watched picture frame in the time, the present invention also can reduce liquid crystal cells in the rotational response brightness decay that (that is in rotation process) causes in the time.
For the left eye of keeping the user is experienced consistent brightness with right eye, in an embodiment, the ratio of shutter close between the period that the first shutter eyeglass 102 is in the shutter opening period of opening and is in closed condition can equal the ratio of shutter close between the period that the second shutter eyeglass 104 is in the shutter opening period of opening and is in closed condition haply, in other words, in first, the second shutter eyeglass 102,104 constantly in the process that opening and closed condition are switched, (in other words the shutter opening period summation that the first shutter eyeglass 102 is in opening can equal shutter opening period summation that the second shutter eyeglass 104 is in opening haply, the shutter close period summation that the first shutter eyeglass 102 is in closed condition also can equal the shutter close period summation that the second shutter eyeglass 104 is in closed condition haply), because first, the second shutter eyeglass 102, the integral time of 104 unlatching summation/close summation is identical, therefore can make user's left eye experience consistent brightness with right eye.Yet this is not to be restriction of the present invention only as the usefulness of example explanation.For instance, under the integral time of first, second shutter eyeglass 102,104 unlatching summation/close summation identical condition, the number of times that the first shutter eyeglass 102 is in the number of times of opening and is in closed condition might not equal respectively the number of times that the second shutter eyeglass 104 is in the number of times of opening and is in closed condition.
In addition, because first, second shutter eyeglass 102,104 open and close can determine the brightness that the user experiences, therefore, increasing without prejudice to the present invention under the eyeglass open-interval prerequisite of shutter glasses, first, second shutter eyeglass 102,104 opening times and close ratio between number of times, opening time and shut-in time and/or the glasses cycle (that is left eye and right eye respectively see a picture frame cycle) is adjustable, therefore, can reach the purpose of adjusting the ambient brightness that the user sees.
Please note, in above-described example, for the video output device 110 that operates in lower picture update rate (for example 120Hz), to be used as a glasses cycle (that is left eye and right eye respectively see a picture frame cycle) with the picture frame of two picture frames output period, and for the video output device 110 that operates in higher picture update rate (for example 240Hz), then be to be used as a glasses cycle (that is left eye and right eye respectively see a picture frame cycle) with the picture frame of four picture frames output period, yet, this is only as the usefulness of example explanation, but not restriction of the present invention, for instance, for the video output device 110 that operates in lower picture update rate (for example 120Hz), output that can also four or six picture frames is as a glasses cycle, and in these glasses in the cycle, use in the above-mentioned plural number kind control mode any or its make up to control shutter glasses 100, can reach equally the eyeglass open-interval purpose that increases shutter glasses.In brief, the periodicity of shutter glasses 100 not necessarily will be equal to the periodicity of picture frame signal.
In addition, in the present invention, it is that backlight module 114 is in full-gear (100% brightness output) and complete shut-down state (0% brightness output) that the opening of backlight module 114 and closed condition do not limit, for instance, when the brightness output of backlight module 114 is higher than the first numerical value (for example 80% brightness output), backlight module 114 is to be considered as entering opening, in addition, when the brightness output of backlight module 114 was lower than second value (for example 20% brightness output), then backlight module 114 was to be considered as entering closed condition.Generally speaking, the opening of backlight module 114 and closed condition can be defined according to the demand in the design.
The above only is the preferred embodiments of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
