A 3D video frame can not contain both the left eye and right eye images simultanously.
Each time a "wobble" occurs(every 120th of a second) the video frame changes from left to right or right to left and the white DLP Linik white flash is displayed on the screen to control the active shutter glasses lenses.
The quoted passage was describing how a DMD chip paints a 2D
frame of video. DLPs use the checkerboard format to use half
the number of mirrors in order to render all
of the number of pixels. And 120th of a second is very fast to me.
From the preceding paragraph
Figure a. is a representation of the left and right sub-frame pixels in a DLP (checkerboard) 2D input.
