Abstract
A kind of 3D glasses is provided. The glasses comprise a spectacle frame, two liquid crystal spectacle lenses, and a PFC and a drive circuit which are electrically connected with the liquid crystal spectacle lens. The glasses are characterized in that one of the spectacle lenses is a positive LCD, and the other is a negative LCD. By adopting the positive LCD and the negative LCD and driving the LCDs with the same driving waveform, the drive circuit becomes simpler, the PFC size is narrowed, and the structure is more concise and delicate.
Description
[technical field]
The utility model relates to the 3D stereoscopic imaging technology, relates in particular to the 3D glasses that are used to watch the 3D stereo-picture.
[background technology]
From the scientific research result as can be known, why the people sees that material object can present stereoeffect, be because about two position difference slightly, the picture of being seen is different, just formed stereoscopic sensation after being reacted to brain the inside imaging, and if allow the people also have stereoscopic sensation, just need offer the different picture of left and right sides glasses at the picture of seeing broadcast, the glasses that we are worn when watching three-dimensional film play this effect.
The liquid crystal light valve formula 3D display technique of main flow on the market is alternately to play the picture that supplies left eye and right eye to watch by display with certain frequency now, and display will be launched synchronizing signal simultaneously.The liquid crystal light valve glasses are received after this synchronizing signal, adjust the switching of light valve glasses synchronously, just close the light valve shutter of left eye lens when promptly playing the right eye picture, be that light valve presents black attitude and stops light to pass through, the light valve of right eye lens is opened, be that light valve presents white attitude, allow light to pass through; But when switching to the left eye picture, then open the left eye light valve and close the right eye light valve.When display is play with very high frequency, brain will with about two width of cloth pictures merge voluntarily, so can see three-dimensional effect.
Conventional liquid crystal light valve formula 3D glasses are made up of the LCD of two positivities, provide the drive waveforms that provides different respectively by driving circuit when work, as shown in Figure 2.Such driving circuit is formed comparatively complicated, and driving circuit generally is installed in a side of glasses, in order to drive the eyeglass of an other side, needs long FPC that drive signal is transferred on the eyeglass of opposite side.This long FPC has also caused sizable technology difficulty when the assembling glasses.
[summary of the invention]
The utility model provides a kind of and has driven with same waveform as at above problem, has dwindled the 3D glasses of PFC size and designs simplification driving circuit.
The technical solution of the utility model is: described 3D glasses, the PFC, the driving circuit that have spectacle frame, two liquid crystal glasses sheets, are electrically connected with the liquid crystal glasses sheet is characterized in that described lens is a slice positivity LCD and a slice negativity LCD.
The beneficial effects of the utility model are: adopt one positive one negative not same sex LCD, can drive with same drive waveforms, it is fairly simple that driving circuit becomes, and dwindled the PFC size, constructs more succinct exquisite.
[description of drawings]
Fig. 1 is the utility model one example structure synoptic diagram;
Fig. 2 is original drive waveforms figure scheme;
Fig. 3 is existing drive waveforms figure scheme.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: described 3D glasses, have spectacle frame 2, two liquid crystal glasses sheets 1, the PFC3 that is electrically connected with the liquid crystal glasses sheet, driving circuit 4, and it is characterized in that described two lenses are a slice positivity LCD1.1 and a slice negativity LCD1.2.
Side at spectacle frame 2 has PFC3, is provided with driving circuit 4 on PFC3, is electrically connected lens 1 and is controlling lens, by drive waveforms, drives the switching that changes the 3D lens regularly.
When watching three-dimensional display, display will be launched synchronizing signal.The 3D glasses receive and adjust the switching of light valve glasses synchronously after this synchronizing signal, just cut out the light valve shutter of left eye lens when promptly playing the right eye picture, be that light valve presents black attitude and stops light to pass through, the light valve of right eye lens is opened, and promptly light valve presents white attitude, allows light to pass through; But when switching to the left eye picture, then open the left eye light valve and close the right eye light valve.When display is play with very high frequency, brain will with about two width of cloth pictures merge voluntarily, so can see three-dimensional effect.
The beneficial effects of the utility model are: adopt one positive one negative not same sex LCD, can drive with same drive waveforms, it is fairly simple that drive circuit becomes, and dwindled the PFC size, constructs more succinct exquisite.
