Enhance driving modulation method and the device for field sequential color liquid crystal display

A enhance driving modulation method and the device for a field sequential color liquid crystal display, comprising steps:

• providing a multi-color backlight source sequentially emitting at least two colored backlights;
• providing a liquid crystal optical gate illuminated by said colored backlights and having a light blocking state and a light permeable state;
• and
• providing a timing signal having a normal state, a metastable state, and an enable state, wherein said timing signal is normally at said metastable state and switched to said normal state and said enable state to drive said liquid crystal optical gate to said light blocking state or said light permeable state, whereby said liquid crystal optical gate creates a light transmission curve having a transit delay in a transition between each two of said normal state, said metastable state and said enable state.
