Abstract
A sequential pattern comprising contiguous black frames inserted between left and right 3D video and/or graphics frames may be displayed on an LCD display. The pattern may comprise two or three contiguous left frames followed by contiguous black frames followed by two or three contiguous right frames followed by contiguous black frames. The left and/or right frames may comprise interpolated frames and/or may be displayed in ascending order. The contiguous black frames are displayed longer than liquid crystal response time. 3D shutter glasses are synchronized with the black frames. A left lens transmits light when left frames followed by contiguous black frames are displayed and a right lens transmits light when right frames followed by contiguous black frames are displayed. A 3D pair of 24 Hz frames or two 3D pairs of 60 Hz frames per pattern are displayed on a 240 Hz display.
