Description

A kind of 3D glasses that improve stereoeffect

Technical field

The utility model relates to a kind of 3D glasses that improve stereoeffect, and it is by making two to see in order or simultaneously different images, the relevant utility model of employed 3D glasses in device for displaying stereoscopic images.In more detail, be exactly in device for displaying stereoscopic images, incide about the observer image of two demonstration, according to different needs, in the 3D glasses, see through or block, this demonstration intercepts the unnecessary light that occurs in the external environment condition outside observer's eyes, and proceeds to intercept in the 3D glasses, thereby improves the relief scheme of stereopsis.The 3D glasses of this improvement, by basic polaroid glasses and LCD shutter glasses, and show together can see through the transmission region of image, and block the zone of opacity that unnecessary light incides in observer's eye and consist of.

Background technology

Utilize two parallax, carry out the technology of device for displaying stereoscopic images, for a long time, the motion of a variety of methods has been arranged.Wherein representative one is, it is upper to make the one dimension demonstration remain on certain distance, the 3D glasses use polaroid glasses or LCD glasses, make the observer about two whiles or see successively different images, be to make observer oneself experience relief method.At US4,884,876, US5 in 821,989 grades, has proposed to use the LCD shutter glasses at CRT, and the 3D that makes the binocular parallax type shows.At .US6,529,175, US6 among 727,867, the KR10-2010-41718 etc., has proposed the drive scheme of LCD shutter, reduces power consumption and improves the 3D image quality, dwindles the technical matterss such as cross effect scheme.At US6, in 266,106, proposed to make the angle of LCD spectacle plane to tilt about 5 degree, about making two more close, thereby dwindle the scheme of cross effect, at USD613, among 328S and the KR10-2010-0021058, propose a kind of user of allowing and used the more easily design proposal of 3D glasses, at US7, the scheme of the senior glasses of multi-usage has been proposed among 062,797 B2.In KR10-2009-0127973, automatic identification observer audiovisual angle has been proposed, automatically carry out the scheme of optimization driving according to the LCD polarization direction of 3D glasses.

Utilize two parallax, the holographic display device of use on the LCD glasses, in showing, one dimension is shown to respectively in order left and right sides binocular vision information, when showing the image that the left side eyes can be seen, the LCD optical shutter of the left side glasses of LCD glasses is in transmission state always, the LCD optical shutter of right side glasses is in blocked state always, corresponding left-eye images, only having left eye to have sees, right eye can not see, in contrast, and when corresponding right-eye image shows, can only be seen that by right eye left eye can not be seen.Identical therewith, can be about the observer two at the moment, per second shows the words of the image more than 30 times in order, the dynamic image that one dimension is shown produces stereoscopic sensation, thereby look it is the dynamic image (3D) of 3 dimensions. still, if the frame frequency of two image is not very high about being shown to, the scintillation of picture will occur, minimize for this problem is reached, the frame frequency that one dimension shows must reach high.Simultaneously, if the frame frequency that one dimension shows uprises, the switching speed of proportional LCD optical shutter also will accelerate therewith.In the case, if the words that the reaction velocity of LCD optical shutter is fast not, two image causes motion blur phenomenon can for the another eyes about originally being shown to respectively, simultaneously also the cross effect phenomenon can occur, can the damage stereoscopic sensation, picture is overlapping, and the state of picture also can variation, the light transmission rate of LCD optical shutter also can step-down, and the dimmed problem of picture can occur.

According to The Physics of Liquid Crystals (by P.G. De Gennes, 1993), Liquid Crystals (by S. Chandrasekhar, 1977), Liquid Crystal Device Hand Book (Science Council of Japan, the 142nd council edits), the reaction velocity of LCD optical shutter depends on the thickness of liquid crystal cell (liquid crystal box), the rotary viscosity of liquid crystal, voltage, the elasticity coefficient of liquid crystal, the electrode resistance of liquid crystal cell (sheet resistance), electric capacity of liquid crystal cell (capacitance) etc.; The driving area of the LCD glasses that are made of same liquid crystal cell is larger, and the capacity area of liquid crystal cell becomes ratio therewith, also can become accordingly large.It is large that the electric capacity of liquid crystal cell becomes, and when supply same voltage and current, liquid crystal cell arrives the time of saturation voltage, according to the RC time constant, understands elongatedly, and the reaction velocity of liquid crystal cell is also had negative effect, and it is large that the consumption of electric power also can become.

By the 3D glasses, the light that incides observer's eyes, be divided into above the stereo display out light and the light of display outside incident.The light that enters to shine in the display surrounding enviroment, continue to incide the observer about on two, about display is supplied with, use picture image for two, will be more.In general, TV uses in bright environment, incides the light of observer's glasses around the display, and the interference of anti-shadow can be provided in the stereopsis information that provides in display, reenter in the eye that is mapped to the observer, the stereoscopic sensation of original 3D stereopsis will weaken.

Like that, in the surrounding enviroment of display, because unnecessary light incides in observer's the eyes, similar phenomenon in the device for displaying stereoscopic images of polaroid glasses mode, also can occur in the phenomenon that the stereoscopic sensation that causes weakens.

Fig. 1 is the synoptic diagram of a side of traditional 3D glasses, to utilize the mode of binocular parallax, uses the 3D glasses on device for displaying stereoscopic images, is polaroid glasses or a side synoptic diagram of LCD optical shutter glasses.11 is spectacle-frame, and 12 is lens.The integral body of lens 12 is identical optical characteristics.In the LCD optical shutter mode, the integral body of lens 12 is by the same light and shade of switch, the transmitance of light is generally 25 ~ 33% level under the bright state, in the polaroid glasses mode, the integral body of lens 12 is polarized condition, about two have respectively 90 the degree phasic differences, in general the transmitance of light is about 40 ~ 48%.That is, the light that in display, shows, integral body is identical state in lens 12, passes through or obstruct.Therefore, outside the image information that occurs in the 3D display, the light that enters to shine in the display surrounding enviroment, also logical lens 12 incides in observer's the eye simultaneously.The amount of the light that enters to shine in the display surrounding enviroment is more comparatively speaking, then can be fewer otherwise will show the quantity of information of relief demonstration, just will produce the problem of the stereoscopic sensation reduction of 3D picture.
