Is there any one know what does gray-to-gray response time mean.
Response time is defined as the time required for an LCD pixel to change
from fully active (black) to fully inactive (white), then back to fully
active again. Many manufacturers, on the other hand, report their LCDs'
gray-to-gray response times, but there have no clear definition for it.
As I understand, LCD monitor change the liquid crystal stage when the colour
signal change. The liquid crystal would not change if the colour signals
remains in same colour. Measuring the response time can easily input a
colour signal which change from black to white or white to black.
Measuring Gray-to-Gray response time is different according to some
manufacturers website. The measurement seems like measuring the liquid
crystal change from one gray colour into another gray colour level. If like
this, why the response times will longer then Tr +Tf (Black to Write, Write
to Black) response time?
If the measurement for gray-to-gray response time which is changing the
liquid crystal from gray colour change into different color and change back
to gray colour again. It cannot be 2ms fast. The faster signal input for LCD
monitor can be 85Hz. The colour signals will have 11ms apart. Two colour
signal which take 22ms. How can it take 2ms for the gray colour into
different color and change back to gray colour again?
Does any one know the standard method of measuring gray-to gray response
time?
