6. Response Time
Response time ton and toff are defined
by formulas (5) and (6) respectively.
ton = t1 – tON ... (5)
toff = t2 – tOFF ... (6)
t1: time which gives 10% transmittance
of the panel.
t2: time which gives 90% transmittance
of the panel.
The relationships between t1, t2, tON
and tOFF are shown in the right figure.

7. Flicker
Flicker (F) is given by the formula (7). DC and AC (MAC16/SVGA/VGA/PC98/NTSC: 30Hz, rms, PAL:
25Hz, rms) components of the panel output signal for gray raster
mode are measured by a DC voltmeter
and a spectrum analyzer in System
II
.
F [dB] = 20log { AC component
DC component
8. Image Retention Time
Image retention time is given by the following procedures.
Apply a monoscope signal to the LCD panel for 60 minutes and then change this signal to the gray scale of
Vsig = 7.0 ± V
AC
[V] (V
AC
: 3 to 4V) so as to give the maximum image retention. Hold input signal V
AC
. The
time for the residual image to disappear gives the image retention time.
Monoscope signal conditions
Vsig = 7.0 ± 4.5 or 7.0 ± 2.0 [V]
(shown in the right figure)
Vcom = 6.6V
R, G, B input signal voltage for gray raster mode is given by
Vsig = 7.0 ± V
50
[V]
where: V
50
is the signal amplitude which gives 50% of
transmittance in V-T curve.
