※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
[ON Sequence]
(1) 3V 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 T3: 30us or more
Time required to release COM related latch circuit initialization which is initializing using DISP signals
(4) TCOM polarity initialization time T4: 30us or more
Time required initializing TCOM polarity accordingly to EXTCOMIN input
[Normal Operation]
Duration of normal driving
[Off Sequence]
(5) Pixel memory initialization time T5: 1V or more
(6) VA, VB, VCOM initialization time T6: 1V or more
(7) 3V falling time (Depends on IC)
[Remark] Precaustions at ehte time of power on and power off.
Remark 1)When power on , VDD and VDDA are same time or VDD should be faster than the VDDA.
Remark 2) When power off, VDD and VDDA are same time or VDDA shoud be faster than the VDD.
