Time of reaction LCD - Marketing, Mits, facts Review

Posted on Sunday, October 03 2004 @ 02:14:28 CEST by LSDsmurf |
Monitors’ specifications given by the manufacturers note the time of pixel reaction when changing all subpixels ( three in one pixel ) from black to white and then back to black. This is a total time, consisting of the rise time ( black – white ) and fall ( eclipse of a pixel : white – black ). It should not suggest that once risen, pixel goes back to its previous – black – position right away. We would then experience a constant blinking effect ( passive mould ). It would be an occurence similar to that experienced with CRT monitors with picture refreshing. Thanks to moulds being passive and condensers included in them, they are able to remember the last position of a crystal ( voltage ).Thanks to constant voltage – they do not go back to their start position, so that picture with 60Hz frequency on an active mould is stable and does not blink like in CRT monitors. Essentially: one change of a picture in time of 1/60Hz ( ~ 16ms ) causes at best one colour change on an activ mould, as it may turn out to be unnecessary to change anything else ( when displaying static graphic ).
