Afterwards, foregoing electronic polarizer is controlled, so that polarization light is passed through, is shown, the eyes of such user are seeing screen
When, completed because liquid crystal is inverted, so that motion blur phenomenon is reduced.
For example, it is assumed that liquid crystal flip-flop transition is t, at the time of mainboard receives T2 signals, timing can be started, in timing
When duration reaches t, then it can determine whether out that the liquid crystal in screen is inverted and complete, and then perform follow-up method and step.Due to screen
Curtain only refreshes particular row, judges whether the liquid crystal in the screen overturns completion, that is, refers to that the liquid crystal for judging particular row in screen is
No upset is completed.Certainly, other any can realize overturn the judgment mode completed for the liquid crystal in screen, belong to this hair
