The 2D/3D switchable LCD stereoscopic display is based on the method of chromatic stereoscopic frame separation that occurs between the left and right eye with the use of two spectrally independent backlight sources with primary color sets RGBLeft and RGBRigth. Semiconductor lasers and/or LEDs with narrow band spectral filters could be used as backlight sources. In a 3D mode, the RGB sources illuminate alternatively and synchronously with the alternative displaying of stereo pair frames. Glasses with chromatic filters are used for watching in 3D mode and separate light from two RGB sources between the eyes of the viewer and in that way separate stereoscopic frames. In a 2D mode, any one of the RGB sources would work. In this case, the display looks like an ordinary display. Two RGB sources could be used for color enhancement in 2D mode. The quality of the images in 3D mode is the same as in 2D. Frame frequency is two times less in 3D mode as compared to 2D. The suggested method competes with two known methods for LCD that use glasses: "Shutter-Glasses Method" and "Polarization Method." It has certain advantages: image quality and stereo channel separation are independent from viewing angle or head tilt of viewer, and there are no active components in the glasses.
