Background technology
In recent years, 3 D stereo shows and is just progressively well known, and it, by providing the left and right view with parallax to respectively the right and left eyes of people, thus producing depth perception, brings more real visual impact and enjoyment. At present, relatively common on the market is two kinds of eyeglass stereoscopic Display Techniques: shutter and polarization type. Two kinds of technology differ from one another, dog-eat-dog in the market share. But, the scintillation that shutter Display Technique exists is always up the key that this technology is hacked. The scintillation that people pay close attention to is often the scintillation of display screen display content itself, because 3D shutter glasses is mostly with the frequency scintillation of 50Hz or 60Hz at present, there is flickering when showing large area height gray level image, the flicker under normal condition is actual and inconspicuous. But nearest research finds that common lighting environment light is likely to produce to be inherently more serious flickering than display screen with shutter glasses combined effect, causes serious visual fatigue.
For China, the LED (light emitting diode) of common illumination fluorescent lamp and employing resistance-capacitance depressurization power drives is subject to the impact of adopted power frequency, and their light modulation frequency is 100Hz, is the twice of power frequency. And the simple eye modulating frequency of the shutter glasses of shutter stereo display is mostly 60Hz, when watching the environment light of 100Hz through shutter glasses, can produce the modulating frequency composition of 40Hz even 20Hz according to difference frequency control principle, human eye is more sensitive to the flicker of these low-frequency components.Only such environment light is closed the extra ratio screen that environment light and shutter glasses interaction generation just can be completely eliminated and is inherently more strong flickering.
