Description

The method of shutter glasses and control shutter glasses

Technical field

The invention relates to the technology of watching stereo-picture, refer to a kind of especially in order to the shutter glasses of watching the stereo-picture that video output device appears 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 pursued, but tool third dimension and the more image demonstration of the sense of reality.The stereo-picture technique for displaying mainly can be divided into two kinds at present; 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 lets left eye and right eye see the pictures different frame respectively exactly, and then makes brain that two pictures different frames of being seen respectively are regarded as stereo-picture.

To shutter glasses, it is used for the stereo-picture that lets the user watch video output device to appear at present widely, and shutter glasses can have two shutter eyeglasses; And open the suitable switching of closing and allow eye viewing that user's left eye watches left-eye image and user to eye image with the shutter eyeglass via the shutter eyeglass; Generally speaking, each shutter eyeglass of shutter glasses is between opening and closed condition, constantly to switch, for instance; When the shutter eyeglass of corresponding left eye when a certain special period is opened; The shutter eyeglass of corresponding right eye just can not opened, and when the shutter eyeglass of corresponding right eye during in special period unlatching also, the shutter eyeglass of corresponding left eye just can not be opened; Therefore, the ambient brightness that the user experienced just can be less than the ambient brightness of reality; Also on the one hand, based on the polarization direction that the image light of the video output device that is suitable for is exported, the shutter glasses sector-meeting of the shutter glasses of being arranged 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, and therefore, also can make ambient brightness that the user the experienced ambient brightness less than reality.When the ambient brightness that the user experienced of wearing 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 remote controller) of exterior domain; Therefore, tend to cause the user in the inconvenience of watching on the stereo-picture.

Moreover, if being the control of application 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 stated; Under the controlling mechanism of convention, two shutter eyeglasses of shutter glasses are to open alternately, therefore; When the liquid crystal layer of shutter eyeglass does not apply voltage and when allowing light penetration, also the liquid crystal layer of a shutter eyeglass just need apply voltage to block light penetration, therefore; If it is long more that the shutter eyeglass is in the time of closed condition, then the power consumption of shutter glasses also increases thereupon.

Embodiment

See also Fig. 1, Fig. 1 is applied to watch the function block schematic diagram of the shutter glasses of the stereo-picture that video output device appears for the present invention.In present embodiment, shutter glasses 100 includes (but being not limited to) first shutter eyeglass 102, the second shutter eyeglass 104 and control circuit 106.One of first, second shutter eyeglass 102,104 (the for example first shutter eyeglass 102) is in order to watching left-eye image, and also one (the for example second shutter eyeglass 104) of first, second shutter eyeglass 102,104 then is in order to watch eye image.In addition; Control circuit 106 is to export control signal S1, S2 respectively to first, second shutter eyeglass 102,104, between opening and closed condition, switches in switching between opening and the closed condition and controlling the second shutter eyeglass 104 to control the first shutter eyeglass 102, for instance; Has liquid crystal layer respectively in first, second shutter eyeglass 102,104; Therefore, control signal S1, S2 can be control voltage, and the rotation that is used for controlling liquid crystal cells in the liquid crystal layer (LC cell) is to reach the purpose of control light penetration rate; Yet; This is not to be used as restriction of the present invention, for example only as the usefulness of example explanation; Any structure with the control of light penetration rate all can be used to realize first, second shutter eyeglass 102,104, can reach the purpose that first, second shutter eyeglass 102,104 of control switches between opening and closed condition equally.

In the present invention; Above-mentioned " closed condition " is meant first, second shutter eyeglass 102,104 light tight fully (that is the light penetration rate is 0%); Therefore; As long as first, second shutter eyeglass 102,104 is not to be light tight fully (that is the light penetration rate is not to be 0%), just can be considered and be in " opening ", for instance; When first, 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, second shutter eyeglass 102,104 just can be considered and is in opening.In brief, when the light penetration rate of first, second shutter eyeglass 102,104 greater than 0% (but being less than or equal to 100%), then first, second shutter eyeglass 102,104 just gets into opening.

Shutter glasses 100 is to be available for users to wear the stereo-picture to watch video output device 110 to be appeared.For instance, in embodiment shown in Figure 1, video output device 110 can be a LCD, 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 the left eye or the right eye that whether can get into the user via shutter glasses 100 via the image light output that display screen 112 is produced.Please note; It is LCD that video output device 110 does not limit; That is; Video output device 110 can also be that any collocation in the lump with shutter glasses 100 used to present the video output device that stereo-picture gives the user, for example Organic Light Emitting Diode (Organic Light-Emitting Diode, OLED) display, plasma display panel, employing digital light treatment technology (Digital Light Processing; DLP) display/projector, employing liquid crystal on silicon (Liquid Crystal on Silicon, LCoS) display/projector of Display Technique or the like.

Shutter glasses 100 can suitably be controlled first, second shutter eyeglass 102,104 through control circuit 106 and between opening and closed condition, switch; Thereby can watch under the stereo-picture not influencing the user, promote the ambient brightness that the user experienced of wearing shutter glasses and/or the power consumption that reduces shutter glasses.Shutter glasses 100 can be through wire transmission or wireless transmission (for example infrared transmission, ZigBee transmission, ultra broadband (Ultrawideband; UWB) transmission, WiFi transmission, radio frequency (Radio Frequency; RF) transmission, DLP light signal or blue bud (Bluetooth) transmission) and receive reference information SC from video output device 110, and 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 come to produce voluntarily desired control signal S1, S2 based on reference information SC; In other words; Video output device 110 only provides synchronizing signal and first, second control information when shutter eyeglass 102,104 will be opened 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 is provided based on video output device 110 itself; In addition; Reference information SC can also directly be the control information (that is dominate first, second shutter eyeglass 102,104 by video output device 110 and when will open or close) of first, second shutter eyeglass 102,104; And control circuit 106 just merely produces corresponding control signal S1, S2 based on the reference information SC that is received; Note that the above only as the usefulness of example explanation, but not restriction of the present invention.

In the present embodiment; But the controlling mechanism summary of first, second shutter eyeglass 102,104 is divided into two kinds: a kind of is that video output device 110 operates in the shutter eyeglass controlling mechanism under the low picture update rate (for example 60Hz or 120Hz), and also a kind of be that video output device 110 operates in the shutter eyeglass controlling mechanism under the higher picture update rate (for example 240Hz or 480Hz).Below come explanation further to be provided with a plurality of examples respectively to the operation of these two kinds of shutter eyeglass controlling mechanisms.

See also Fig. 2, Fig. 2 is the sequential chart that is applied to first kind of control mode of shutter glasses shown in Figure 1 100.In this example; Video output device 110 operates under the low picture update rate (for example 60Hz, 96Hz, 100Hz, 110Hz or 120Hz), and is as shown in Figure 2, and video output device 110 (for example shows first picture frame (for example L1, L2, L3 or L4) and second picture frame (for example R1, R2 or R3) among the T1～T7) alternately respectively at a plurality of picture frames output periods; Wherein one of first, second picture frame is to be the left-eye image frame; And first, second picture frame one is to be the eye image frame also, in other words, and 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, yet, in an embodiment also; 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 image-driven time and image stabilization time; For example 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.Please note; Based on the Display Technique that is adopted; Each image stabilization time can comprise that non-image driving time or image hold time, and for instance, has transmitted the image-driven signal in the time or in image stabilization transmitted image drive signal not in the time in image-driven; So picture frame can be considered at this moment and is in stable state; For example, to pixel (liquid crystal cells or Organic Light Emitting Diode unit), lighted and to be regarded as getting into the image stabilization time when image-driven has transmitted the image-driven signal in the time and made arbitrary pixel itself reach the stable time; Also on the one hand, light for the time of arbitrary pixel also to can be considered from transmitted image drive signal not and get into the image stabilization time.In each image-driven in the time; Display screen 112 (for example display panels) can be according to video data from top to bottom line by line by end with the leftmost side to the rightmost side of delegation set in regular turn each pixel with the present picture frame exporting present desire and show (in other real work in the mode; Based on the modes of emplacement of display panels or the difference of design; Also can be from bottom to top set each pixel in regular turn with the present picture frame exporting present desire and show or the pixel that adopts other new sequences more by ending line by line) with the rightmost side to the leftmost side of delegation; Generally speaking; Display screen 112 can replace the previous image frame that has before shown with the present picture frame that present desire shows; Therefore, the present picture frame that present desire 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 result 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 desire shows reaches stable, and for example display screen 112 can not come driving pixels based on any video data, that is; Each image stabilization time can be a vertical blanking at interval (vertical blanking interval, VBI).

As previously mentioned; Control circuit 106 can switch between opening (" ON ") and closed condition (" OFF ") by the control first shutter eyeglass 102; And control the second shutter eyeglass 104 and between opening (" ON ") and closed condition (" OFF "), switch; And in this example; The control circuit 106 controls first shutter eyeglass 102 can be in opening in specific first picture frame (for example L1, L2 or L3) the pairing image stabilization time (for example TH1, TH2 or TH3); And be in opening constantly and in specific second picture frame that is right after specific first picture frame (for example R1, R2 or R3) the pairing image-driven time (for example TP1 ', TP2 ' or TP3 '), switch to closed condition by opening, as shown in Figure 2, in present embodiment; The starting point of the first shutter eyeglass 102 in the image stabilization time switches to opening by closed condition, and before the end point of follow-up image-driven time, just switches to closed condition by opening.Also on the one hand; The control circuit 106 controls second shutter eyeglass 104 switches to opening by closed condition in specific second picture frame (for example R1, R2 or R3) the pairing image-driven time (for example TP1 ', TP2 ' or TP3 '); And be in opening constantly and still can be in opening in same specific second picture frame (for example R1, R2 or R3) the pairing image stabilization time (for example TH1 ', TH2 ' or TH3 '); As shown in Figure 2; In present embodiment; The second shutter eyeglass 104 just switches to opening by closed condition in the image stabilization time that is arranged in the image-driven times prior, and just switches to closed condition by opening up to the end point of image-driven time.

Therefore, the end point of specific pairing image stabilization time of first picture frame and the first shutter eyeglass 102 are switched to the corresponding first shutter opening period (for example P1, P2 and P3) between the time point of closed condition in the pairing image-driven of specific second picture frame by opening in the time; Likewise, the second shutter eyeglass 104 corresponding second shutter opening period (for example P1 ', P2 ' and P3 ') between the end point of the pairing image-driven of specific second picture frame is switched to opening by closed condition in the time time point and specific second picture frame pairing image-driven time.Note that first, second shutter opening period is part overlapping (for example P1 and P1 ' partly overlap, and P2 and P2 ' part overlap, and P3 and partly overlapping of P3 ').

In other words; Based on the time sequential routine shown in Figure 2; The control circuit 106 controls first shutter eyeglass 102 can be in opening in the pairing image stabilization of specific first picture frame among the time; And control the second shutter eyeglass 104 and can be in opening among the time in the pairing image stabilization of specific second picture frame that is right after this specific first picture frame; In addition, control circuit 106 also can be controlled first, second shutter eyeglass 102,104 and only can in single continuous time, be in opening simultaneously in the pairing image-driven of this specific second picture frame among the time.

Please note; Fig. 2 only demonstrates control circuit 106 and (for example controls the operation of first, second shutter eyeglass 102,104 among the picture frame output period T1～T6) in one period operating time; And in fact, control circuit 106 still can be constantly in previous operating time (the for example picture frame output period before the picture frame output period T1) and follow-up operating time (the for example picture frame output period after the picture frame output period T6) based on perhaps different glasses cycle and repeat same controlling mechanism and control first, second switching of shutter eyeglass 102,104 between opening and closed condition in identical glasses cycle (that is left eye and right eye respectively see the image once frame cycle).To the operation that mixes the different glasses cycle, please consult Fig. 2 and Fig. 3 in the lump, Fig. 3 be that operation shown in Figure 2 is based on pairing continuity sequential chart under the notion in mixing different glasses cycle.As shown in Figure 2; 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 increases; So in this example, first shutter glasses, 102 follow-up starting points in the pairing image stabilization time T of first picture frame L5 H5 just switch to opening by closed condition, and second shutter glasses 104 is follow-up among the pairing image-driven time T of second picture frame R5 P5 ', just switches 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 pairing picture frame output period in glasses cycle is to adjust according to the demand on using.In addition; In the above-mentioned mixing example in different glasses cycles; Be to repeat same controlling mechanism in the cycle in long glasses also, yet, in these long glasses in the cycle; Also can extra doping other controlling mechanism (for example follow-up other the controlling mechanism that provides); And (for example among the T7～T8), control the On/Off of shutter eyeglass, the variation spirit also according to the invention in this design through other controlling mechanism in controlling mechanism is not originally carried out any On/Off control to the shutter eyeglass period.

As previously mentioned, display screen 112 can comprise a part of present picture frame and a part of previous image frame in the output result of image-driven in the time, therefore; Get into user's eyes for fear of the rubbish image, in this example, backlight module 114 only can be opened (" ON ") in image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, TH3 '; In other words, backlight module 114 is closed (" OFF ") in image-driven time T P1, TP1 ', TP2, TP2 ', TP3, TP3 ', therefore; Owing to lack required backlight, the demonstration of display screen 112 in image-driven time T P1, TP1 ', TP2, TP2 ', TP3, TP3 ' exported and can't be seen by the person's of being used eyes, therefore; Though first, second shutter eyeglass 102,104 is opened in image-driven time T P1 ', TP2 ', TP3 '; But in fact can not influence watching of stereo-picture, yet but increase the opening time of first, second shutter eyeglass 102,104 to some extent; Therefore; Can promote the ambient brightness that the user experiences, in addition since opening time of first, second shutter eyeglass 102,104 be increased; The shut-in time of first, second shutter eyeglass 102,104 just reduces accordingly, so also can reduce the power consumption of shutter glasses 100.

Please note; In also one doing in the mode in fact; Backlight module 114 is except being held open in image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, TH3 '; The backlight open period of backlight module 114 also can be expanded forward from the starting point of image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, TH3 ' a little, and/or expands a little backward from the end point of image stabilization time T H1, TH1 ', TH2, TH2 ', TH3, TH3 ', in other words; Backlight module 114 can just switch to opening by closed condition before the starting point of image stabilization time; And/or after the end point of image stabilization time, switch back closed condition by opening again, that is the backlight open period that backlight module 114 is in opening can be contained the image stabilization time and greater than the image stabilization time.In brief; Backlight module 114 can be in opening in image stabilization among the time; And can be in closed condition in adjacent image-driven among the time, and backlight module 114 is in closed condition in this image-driven in the time time span is the time span that is less than or equal to this image-driven time.

As shown in Figure 2; The first shutter eyeglass 102 just can switch to opening by closed condition in the starting point of image stabilization time T H1, TH2, TH3; And second shutter eyeglass 104 just can switch to closed condition in the end point of image stabilization time T H1 ', TH2 ', TH3 ' by opening, yet the present invention is not as limit; See also Fig. 4, Fig. 4 is the sequential chart that is applied to second kind of 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 image stabilization time T H1, TH2, TH3; And second shutter eyeglass 104 after the end point of image stabilization time T H1 ', TH2 ', TH3 ', just switch to closed condition by opening; Thus; Except first, second shutter opening period P1～P3 originally and P1 '～P3 '; For the second shutter eyeglass 104, the end point of specific pairing image stabilization time of second picture frame and the second shutter eyeglass 104 are switched to the corresponding first shutter opening period (for example P4, P5 and P6) between the time point of closed condition in the pairing image-driven of specific first picture frame that is right after by opening in the time; In addition; For a shutter eyeglass also, the first shutter eyeglass 102 is the corresponding second shutter opening period (for example P4 ', P5 ' and P6 ') between the end point of the pairing image-driven of specific first picture frame is switched to opening by closed condition in the time time point and specific first picture frame pairing image-driven time.Please note; Partly overlapping of first, second shutter opening period (for example P1 and P1 ' part overlapping except script; P2 and P2 ' part overlap, and P3 and the overlapping of P3 ' part) in addition, also can partly overlapping equally first, second newly-increased shutter opening period, (for example P4 and P4 ' part overlaps; P5 and P5 ' part overlap, and P6 and the overlapping of P6 ' part).

As previously mentioned, though first, second shutter eyeglass 102,104 is opened, in fact can not influence watching of stereo-picture in image-driven time T P1 ', TP2 ', TP3 '; Yet; The opening time of first, second shutter eyeglass 102,104 but increases to some extent, therefore, can promote the ambient brightness that the user experiences; In other words; Do not influencing under the prerequisite of watching of stereo-picture, as if increasing by first above-mentioned unlatching period and/or the time span of the second shutter opening period, just can promote the user further the ambient brightness of being experienced.See also the 5th～10 figure (its be respectively shutter glasses 100 shown in Figure 1 the third～sequential chart of the 8th kind of control mode); In Fig. 5, Fig. 7, Fig. 8 and example shown in Figure 10; The time span of the first shutter opening period equals second picture frame time span of pairing image-driven time haply; In addition; In Fig. 6, Fig. 7, Fig. 9 and example shown in Figure 10, the time span of the second shutter opening period equals second picture frame time span of pairing image-driven time haply.Because skilled persons will can be understood according to previous explanation among the 5th～10 figure about the running of display screen 112, backlight module 114, the first shutter eyeglass 102 and the second shutter eyeglass 104, so do not give unnecessary details in addition in this easily.

In above-mentioned example; Among the image stabilization time (for example TH1, TH1 ', TH2, TH2 ', TH3, TH3 '); Mainly be that unlatching through backlight module 114 allows the user to see picture frame; And in the above-mentioned shutter opening period (for example P1, P1 ', P2, P2 ', P3 and P3 '); Liquid crystal cells in the liquid crystal layer of the first shutter eyeglass, 102/ second shutter eyeglass 104 just rotates so that the first shutter eyeglass, 102/ second shutter eyeglass 104 switches to opening by closed condition in the image stabilization times prior; 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) caused in the time.

See also Figure 11, Figure 11 is the sequential chart that is applied to the 9th kind of 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 200Hz or 240Hz), yet video output device 110 also can operate under the higher picture update rate (for example 400Hz or 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, still; 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, thus for specification for purpose of brevity, below only operate in 240Hz with video output device 110 picture update rate be the control mode of lucid and lively peephole mirror 100 example.Shown in figure 10, video output device 110 can show one group of first picture frame (for example (L1, L1 '), (L2 alternately; And one group of second picture frame (for example (R1, R1 '), (R2, R2 ')) L2 ')); In addition, video output device 110 is respectively at continuous a plurality of first picture frames output periods (for example (T11, T11 '), (T12; T12 ')) show main first picture frame (for example L1 or L2) and less important first picture frame (for example L1 ' or L2 ') that this is organized first picture frame and is comprised in regular turn in one by one, and respectively at continuous a plurality of second picture frames output periods (for example (T21, T21 '), (T22; T22 ')) show main second picture frame (for example R1 or R2) and less important second picture frame (for example R1 ' or R2 ') that this is organized second picture frame and is comprised in regular turn in one by one; Note that and this organize 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 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, and in real a work in the mode; The display order of picture frame is: L1, L1 ', R1, R1 ', L2; L2 ', R2, R2 ', wherein L1 and L2 are main first picture frame, L1 ' and L2 " be less important first picture frame; R1 and R2 are main second picture frame, R1 ' and R2 " be less important second picture frame, so (L1, L1 ') and (L2; L2 ') constitute one group of first picture frame respectively, and (R1, R1 ') constitutes one group of second picture frame respectively with (R2, R2 '); And also one doing in the mode in fact, the display order of picture frame then is L1, L1 ', L1 ", L1 ' ", R1; R1 ', R1 ", R1 ' ", wherein L1 is main first picture frame, L1 ', L1 ", L1 ' " be less important first picture frame; R1 is main second picture frame, R1 ', R1 ", R1 ' " be less important second picture frame, so (L1, L1 ', L1 "; L1 ' ") constitute one group of first picture frame, and (R1, R1 ', R1 ", R1 ' ") constitutes one group of second picture frame.Note that on the Yu Shizuo that backlight module 114 can give the less important first picture frame L1 ', L1 ", L1 ' " with the less important 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 LCD, 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 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 execution mode; Less important first picture frame is for showing main first picture frame that is arranged in same group first picture frame again; And less important second picture frame is for showing main second picture frame that is arranged in same group second picture frame again; (for example first picture frame is exported period T11 and is included image-driven time T P1 and image stabilization time T H1 though each first picture frame output period and each second picture frame output period have included image-driven time and image stabilization time; Picture frame output period T11 ' includes image-driven time T P1 ' and image stabilization time T H1 ', by that analogy).As previously mentioned, for LCD, the rotation that needs the control liquid crystal cells is to reach the purpose of control light penetration rate; Under lower picture update rate (for example 60Hz or 120Hz); Considering the required rotation time of liquid crystal cells, mainly is to utilize the image stabilization time that is right after after the image-driven time to carry out appearing 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 in the identical time, the LCD that operates under the higher picture update rate can be exported more picture frame; Therefore, the pairing picture frame output period of less important picture frame just capable of using provides and stablizes picture and open first, second shutter eyeglass 102,104 to let the user carry out watching of stereo-picture.In simple terms; Can be responsible for upgrading the previous content (that is content of last main picture frame) of a picture frame before that shown through each main picture frame (for example above-mentioned L1, L2, R1 or R2); Therefore; Before the main picture frame that present desire shows replaced the previous image frame that has before shown fully, the output result of the pairing image-driven of main picture frame in the time that display screen 112 (for example display panels) shows in present desire can comprise a part of present main picture frame and a part of last main picture frame; Also on the one hand, follow-up less important picture frame (for example above-mentioned L1 ', 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 through shutter glasses 100.

In addition; In going back an execution mode; Less important the first/the second picture frame is the lasting output result for main the first/the second picture frame itself in same group the first/the second picture frame; That is, in the pairing image-driven of main picture frame in the time, display screen 112 can be according to video 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 desire and show (in other real work in the mode; Based on the modes of emplacement of display panels or the difference of design; Also can be from bottom to top set each pixel with the main picture frame exporting present desire and show or the pixel that adopts other new sequences more by ending line by line with the rightmost side to the leftmost side of delegation), yet, in the follow-up pairing image-driven of less important picture frame among the time; Display screen 112 does not carry out the display driver operation based on any video 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/the second picture frame can also be that black full picture is perhaps finely tuned the picture that (for example disturbing the compensation of (crosstalk) between the picture frame) produced based on main the first/the second picture frame in same group the first/the second picture frame, can reach the effect of stablizing picture equally.

In addition, in more also in the execution mode, main the first/the second picture frame can also be black full picture, and backlight module 114 can be opened in the output period at the pairing picture frame of less important the first/the second picture frame and carries out watching of stereo-picture for the user.

As previously mentioned; Control circuit 106 can the control first shutter eyeglass 102 in opening (" ON ")) and closed condition (" OFF ") between switch; And control the second shutter eyeglass 104 and between opening (" ON ") and closed condition (" OFF "), switch; And in this example; The control circuit 106 controls first shutter eyeglass 102 is in opening in pairing first picture frame output of specific less important first picture frame (for example L1 ' or L2 ') period (for example T11 ' or T12 '); And be in opening constantly up in pairing second picture frame output of specific main second picture frame that is right after specific less important first picture frame (for example R1 or R2) period (for example T21 or T22), switching to closed condition by opening; Shown in figure 10; In present embodiment, the first shutter eyeglass 102 switches to opening in the starting point of pairing first picture frame output period of specific less important first picture frame by closed condition, and before follow-up specific main second picture frame end point of pairing second picture frame output period, just can switch to closed condition by opening.Also on the one hand; Control circuit 106 is also controlled the second shutter eyeglass 104 and in pairing second picture frame output of specific main second picture frame (for example R1 or R2) period (for example T21 or T22), is switched to opening by closed condition; And be in opening constantly and among pairing second picture frame of specific less important second picture frame that is right after specific main second picture frame (for example R1 ' or R2 ') output period (for example T21 ' or T22 '), still can be in opening; Shown in figure 10; In present embodiment; The second shutter eyeglass 102 just switches to opening by closed condition after specific main second picture frame starting point of pairing second picture frame output period, and just can switch to closed condition by opening in the end point of pairing second picture frame output period of follow-up specific less important second picture frame.

As shown in the figure; The end point of pairing first picture frame of specific less important first picture frame output period and the first shutter eyeglass 102 are exported in the period the corresponding one first shutter opening period (for example P1 or P2) between the time point that is switched to closed condition by opening in pairing second picture frame of specific main second picture frame; And the second shutter eyeglass 104 is exported the corresponding second shutter opening period (for example P1 ' or P2 ') between the end point of period in pairing second picture frame of specific main second picture frame is switched to opening by closed condition in the output period time point and pairing second picture frame of specific main second picture frame; Please note; First, second shutter opening period is part overlapping (for example P1 and P1 ' part overlaps, and P2 and the overlapping of P2 ' part).

In other words; Based on the time sequential routine shown in Figure 10; The control circuit 106 controls first shutter eyeglass 102 can be in opening in pairing first picture frame of specific less important first picture frame among the output period; And control first, second shutter eyeglass 102,104 among pairing second picture frame of specific main second picture frame that is right after this specific less important first picture frame is exported the period, only can in single continuous time, be in opening simultaneously; In addition, control circuit 106 is also controlled the second shutter eyeglass 104 and can be in opening in pairing second picture frame of specific less important second picture frame that is right after this specific main second picture frame among the output period.

Please note; Figure 10 only demonstrates the operation of control circuit 106 first, second shutter eyeglass 102,104 of control in one period operating time (for example picture frame output period T11～T22 '); And in fact, control circuit 106 still can be constantly in previous operating time (the for example picture frame output period before the picture frame output period T11) and follow-up operating time (for example picture frame output period T22 ' picture frame output period afterwards) based on perhaps different glasses cycle and repeat same controlling mechanism and control first, second switching of shutter eyeglass 102,104 between opening and closed condition in identical glasses cycle (that is left eye and right eye respectively see the image once frame cycle).To the operation that mixes the different glasses cycle, please consult Figure 11 and Figure 12 in the lump, Figure 12 be that operation shown in Figure 11 is based on pairing continuity sequential chart under the notion in mixing different glasses cycle.Shown in figure 11; The glasses cycle originally equals the picture frame output period (for example T11+T11 '+T21+T21 ') of four picture frames; Yet; After 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 increases; So in this example, first shutter glasses, 102 follow-up starting points in pairing first picture frame output of the less important first picture frame L4 ' period T14 ' just switch to opening by closed condition, and second shutter glasses 104 is follow-up among pairing second picture frame output of main second picture frame R4 period T24, just switches 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 pairing picture frame output period in glasses cycle is to adjust according to the demand on using.In addition; In the above-mentioned mixing example in different glasses cycles; Be to repeat same controlling mechanism in the cycle in long glasses also, yet, in these long glasses in the cycle; Also can extra doping other controlling mechanism (for example follow-up other the controlling mechanism that provides); 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, the variation spirit also according to the invention in this design through other controlling mechanism.

As previously mentioned, before the main picture frame that present desire shows replaced the previous image frame that has before shown fully, the output result of the pairing image-driven of main picture frame in the time that display screen 112 (for example display panels) shows in present desire can comprise a part of present main picture frame and a part of last main picture frame; Therefore, get into user's eyes for fear of the rubbish image, in this example; Backlight module 114 is only distinguished among corresponding picture frame output period T11 ', T21 ', T12 ', the T22 ' in less important first, second picture frame and is opened (" ON "), in other words, backlight module 114 can in main first, second picture frame institute respectively the picture frame of correspondence export among period T11, T21, T12, the T22 and close (" OFF "); Therefore; Owing to lack required backlight, the demonstration of display screen 112 in picture frame output period T11, T21, T12, T22 exported and can't be seen by the person's of being used eyes, so; Though first, second shutter eyeglass 102,104 is opened in picture frame output period T21, T22; But do not influence watching of stereo-picture, yet, because the increase of the opening time of first, second shutter eyeglass 102,104; Therefore; Can promote the ambient brightness that the user experiences, in addition since opening time of first, second shutter eyeglass 102,104 be increased; The just corresponding minimizing of the shut-in time of first, second shutter eyeglass 102,104 is so also can reduce the power consumption of shutter glasses 100.

Please note; In also one doing in the mode in fact; Backlight module 114 is held open except distinguish corresponding picture frame output period T11 ', T21 ', T12 ', T22 ' in less important first, second picture frame in; The backlight open period of backlight module 114 also can be distinguished the starting point expansion a little forward of corresponding picture frame output period T11 ', T21 ', T12 ', T22 ' from less important first, second picture frame; And/or distinguish the end point expansion a little backward of corresponding picture frame output period T11 ', T21 ', T12 ', T22 ' from less important first, second picture frame; In other words; Backlight module 114 can just switch to opening by closed condition before less important the first/the second picture frame starting point of pairing picture frame output period; And/or after less important the first/the second picture frame end point of pairing picture frame output period, switch back closed condition by opening again; That is; The backlight open period that backlight module 114 is in opening can be contained and greater than the pairing picture frame output period of less important the first/the second picture frame; Wherein backlight module 114 can be in opening in the pairing picture frame of less important the first/the second picture frame among the output period, and can be in closed condition in the pairing picture frame of adjacent main the first/the second picture frame among the output period, and backlight module 114 is in closed condition in the pairing picture frame of this adjacent main the first/the second picture frame in the output period time span is to be less than or equal to this adjacent main the first/the second picture frame time span of pairing picture frame output period.

According to the previous explanation that operates in the shutter eyeglass controlling mechanism under the low picture update rate (for example 60Hz or 120Hz) to video output device 110; Under the situation of spirit of the present invention, design variation miscellaneous is feasible (shown in the 4th～10 figure); Likewise; Operate in the shutter eyeglass controlling mechanism under the higher picture update rate (for example 240Hz or 480Hz) to video output device 110; Other design variation that meets spirit of the present invention also is feasible, shown in the 13rd～19 figure (wherein the 13rd～19 figure is respectively the sequential chart of the tenth kind～the 16 kind of control mode that is applied to shutter glasses shown in Figure 1).Owing to have the knack of this art via reading literary composition and the operation that should understand the example shown in the 13rd～19 figure with reference to correlative type (for example the 4th～10 figure and related description book content) easily in the above specification, so just do not give unnecessary details in addition in this.

Moreover; 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, second shutter eyeglass 102,104 constantly in the process that opening and closed condition are switched; The shutter opening period summation that the first shutter eyeglass 102 is in opening can equal shutter opening period summation (and the one side 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 the unlatching summation of first, second shutter eyeglass 102,104/time of integration of closing summation is identical, so 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 time of integration of the unlatching summation of first, second shutter eyeglass 102,104/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 the number of times that the second shutter eyeglass 104 is in the number of times of opening and is in closed condition respectively.

In addition; Because the open and close of first, second shutter eyeglass 102,104 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; Therefore the unlatching number of times of first, second shutter eyeglass 102,104 and to close ratio and/or glasses cycle between number of times, opening time and shut-in time (that is left eye and right eye respectively see the image once frame cycle) be adjustable, can reach the purpose of the adjustment ambient brightness that the user saw.

Likewise; Distinguish in corresponding picture frame output period (for example T11 ', T21 ', T12 ', T22 ') at less important first, second picture frame; Mainly be that unlatching through backlight module 114 allows the user to see picture frame; And in the above-mentioned shutter opening period (for example P1, P1 ', P2 and P2 '); Liquid crystal cells in the liquid crystal layer of first shutter glasses, 102/ second shutter eyeglass 104 just rotated before the output period so that the first shutter eyeglass, 102/ second shutter eyeglass 104 switches to opening by closed condition in the pairing picture frame of less important first picture frame/less important second picture frame; And just rotate after the output period so that the first shutter eyeglass, 102/ second shutter eyeglass 104 switches to closed condition by opening in the pairing picture frame of less important first picture frame/less important second picture frame; Then when the user in less important first, second picture frame corresponding respectively picture frame when watching picture frame in the output period, the present invention also can reduce liquid crystal cells in the rotational response brightness decay that (that is in rotation process) caused in the time.

Please note; In above-described example; For the video output device 110 that operates in lower picture update rate (for example 120Hz), mainly be to be used as a glasses cycle (that is left eye and right eye respectively see the image once 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 mainly be to be used as a glasses cycle (that is left eye and right eye respectively see the image once 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 and control shutter glasses 100, can reach the eyeglass open-interval purpose that increases shutter glasses equally.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, and when the brightness output of backlight module 114 is higher than first numerical value (for example 80% brightness output); Backlight module 114 is to be regarded as getting into 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 regarded as getting into closed condition.Generally speaking, the opening of backlight module 114 and closed condition can define according to the demand in the design.

The above is merely 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.
