Description
Technical field
The present invention relates to display technology field, particularly relate to a kind of method reducing shutter three dimensional display flickering.
Background technology
Along with the development of human sciences's technology, the domestic electric appliances such as computer, television set, video camera, camera are more and more universal in people's daily life, people often use computer to understand the information of outside and learn, and computer has become people and to have lived indispensable part.
At present, along with the development of display technology, have developed three-dimensional (3D) display of active shutter mode (shutter).Active-shutter 3D display mainly realizes 3D effect by improving the refresh rate of picture, by image frame by frame, form two a series of paintings faces of corresponding left eye and right eye, interlock continuously and show, synchronizing signal (as infrared signal) reflector is by the left and right eyeglass switch of Synchronization Control active shutter type 3 D spectacles simultaneously, enables left and right eyes see respective picture in the correct moment.This technology can keep the original resolution of picture, allows user enjoy real full HD 3D effect very like a cork.
It should be noted that, there is the strong problem of flickering in current active-shutter 3D display, is mainly reflected in active shutter type 3 D spectacles.The frequency of the 3D display glasses left and right sides switch of current picture refreshing frequency 120Hz is 60Hz, but the double frequency opened or closed of each eyeglass is 30Hz, and flicker is serious.
Such as, for the active-shutter 3D display of 120HZ refreshing frequency, eyeglass switching frequency, for 60HZ(, now the eyeglass cycle is 1/60 second) 3D glasses, shown in Figure 1, when the state that display brightness is 100%, the backlight of display pannel is almost always in open mode at (comprising cold-cathode fluorescence lamp and light-emitting diode).
The operating state of display backlight as shown in figure 101, the 3D display of 120Hz refreshing frequency is in continuous 4 eyeglass cycles (1/60 second), and the state of its backlight is open mode always.Now, the operating state of left lens as shown in figure 102, the left lens of 3D glasses is in the cycle of opening (1/60 second); The time of opening front 70% of cycle closes, and the time of rear 30% opens.The operating state of right lens as indicated at 103, right lens is in the closedown cycle (1/60 second); The time in closedown cycle 100% closes.Left side and the operating state of right lens as shown at 104, within each cycle (1/60 second), no matter open cycle or closedown cycle, left and right eyeglass front 70% time be all closedown.
For active shutter type 3 D spectacles, about it, the state that opens or closes of two eyeglasses is contrary within each cycle; The state that opens or closes in each eyeglass adjacent two cycles is also contrary, and said process hockets, thus makes the left eye of user and right eye in different cycles, see the picture seen, the static and dynamic image by persistence of vision formation 3D.
It should be noted that, each shutter eyeglass also only have an appointment within the cycle of opening 30% time in open, this is done to prevent every width 3D picture refreshing initial stage from occurring abnormal, be commonly called as " ghost ".Under the guide of synchronizing signal (infrared or bluetooth), the left and right shutter eyeglass of active shutter type 3 D spectacles alternately opens and closes, and left eye and right eye see the picture (having suitable vision difference) seen respectively, forms third dimension.Situation shown in Fig. 1, the refreshing frequency of display picture is 120Hz, and the switching frequency of two the shutter eyeglasses in left and right is all 60Hz.
Although display is under 240Hz or higher refreshing frequency, flicker can be made to decline a little.Now the double frequency opened or closed of each eyeglass only has 60Hz, and forms the difference frequency of 10Hz with mains frequency, although cost increases a lot, flickering does not have clear improvement.
Also it should be noted that, if just simply increase the switching frequency of the left and right shutter eyeglass of active shutter type 3 D spectacles, there will be picture abnormal problems such as " ghosts ".See Fig. 2, simple increase eyeglass switching frequency, can make glasses before the eyeglass cycle 70% time in see picture, now picture is the refreshing initial stage, at this moment sees that picture just there will be exception.Analyze eyeglass switch motion to find, the operating state of left side and right lens as shown in Fig. 1 105, no matter left side or right lens, the adjacent time interval of opening for twice is 20/600 second, respective frequencies is 30Hz, black field duty ratio (closed condition accounts for the ratio in whole eyeglass cycle) 85%, this is the main cause of eyeglass versus environmental flicker.And can find by experiment, the frequency of corresponding 30Hz, namely black field duty ratio is low to moderate 15%, still has intense flashes to exist.In addition the frequency of 30Hz also will produce the difference frequency of 20Hz and 30Hz with ambient lighting (50Hz or 60Hz), also can produce strong flickering.
Therefore, for existing active-shutter 3D display technology, also not increasing display refreshing frequency, under prerequisite that picture normally shows, effectively cannot reduce film flicker problem, cannot ensure that 3D display picture has good display effect at present.
