8.Sequence
8-1) Power supply sequence
VDD/VDDA（5V）
DISP
EXTCOMIN
SCS
Others
[ON Sequence]
(1) 5V rise time (depends on IC)
(2) Pixel memory initialization T2: 1V or more Initialize with M2 (all clear flag) or write all screen white
(3) Release time for initialization of TCOM latch
(4) TCOM polarity initialization time
[Normal Operation]
Duration of normal driving
[Off Sequence]
(5) Pixel memory initialization time
* Refer to timing chart and AC timing characteristics for detail
* 1 ③ and ④ may be opposite (however, TCOM polarity inversion will not occur even with
EXTCOMIN between DISP=”L”. Also, when DISP and EXTCOMIN are simultaneously started
up, allow 30us or more before SCS starts up (It may be less than 60us).
* 2 Setting value for pixel memory initialization
SCS=Driving accordingly to clear pixel internal memory method (use all clear flag or write all
screen white)
S1=M2 (all clear flag) = “H” or write white
SCLK: Normal Driving
(6) VA, VB, VCOM initialization time
(7) 5V falling time (Depends on IC)
after all clear flag input.
Time required to release COM related latch circuit initialization which is initializing using DISP signals
Time required for initializing TCOM polarity according to EXTCOMIN input
