鍪 The input signal of “MOD” Terminals(Pin No.51 and No.52) must be low voltage when turning on
the power supply, and it is held until more than double vertical periods after VCC
is turned on
completely. After then, it must be held high voltage until turning off the power supply.(Connect
Pin No.51 and No.52 terminals to the same signal.)
ǚNote 7-1ǜThese are standard input voltages for gray scale. When VCOM
is alternated polarity, these
voltage should be alternated polari
ty. V0(black) is different polarity alternating signal of
V
COM. V4(white) is the same polarity alternating signal of VCOM. Center voltage of each
standard input voltage
shift positive way for LCD characteristics (V0ㄩV1ㄩV2ㄩV3ㄩV4).
This sift amount is adjusted so as
to no flicker of each standard
input voltage after
DC bias voltage of V
COM
and V0 is adjusted.
ǚNote 7-2ǜIt must be kept that 3.0Vㄆ(VCC-VSS)ㄆ3.6V.
ǚNote 7-3ǜThe same phase and amplitude with VCOM. VEEDC
is center of V
EE.
ǚNote 7-4ǜDCLK,SPL,SPR,LBR,LP,PS,R0эR5,G0эG5 and B0эB5 terminals are applied.
ǚNote 7-5ǜDCLK,SPL,SPR,LBR,LP,R0эR5,G0эG5 and B0эB5 terminals are applied.
ǚNote 7-6ǜPS terminal is applied.
ǚNote 7-7ǜMOD,CLS,SPS and U/L terminals are applied.
ǚNote 7-8ǜVCOMAC
should be alternated on V
COMDC
every 1 horizontal period and 1 vertical period.
V
COMDC
bias is adjusted so as to minimize flicker or maximum contrast every each
module .
