3 Actual Vofs adjustment (2)
Perform aging with RST MASK 01
(white) displayed for 3 seconds:
MKS S51
Set to RST MASK 14 (yellow egg color).
Set VOL OFFSET to 024 (15 [V] ).
Are there any dark cells?
Gradually increase Vofs data
until dark cells disappear (Vofs should
be 255 (60 [V]) or less).
Is Vofs_min3 144 (38 [V])
or smaller?
Return the Vofs value to the tentative
voltage setting.
Note:
This is for checking the lower limit of Vofs accurately.
Set Vofs_min3 to 024 (15 [V]).
Note:
This setting value becomes the value
for Vofs_min3.
Note: Take note of the value
for Vofs_min3.

Set the highest voltage among Vofs_min1, Vofs_
min2 and Vofs_min3 as Vofs_min.

Note: Take note of the lower limit color of Vofs
(pale purple or sky color or yellow egg
color).
