(7)Electrical characteristics

7-1) Recommended operating conditions

A) TFT-LCD panel driving section

*Cautions when you turn on or off the power

supply

(a) Turn on or off the power supply with simultaneously or the following sequence.

Turn on -- VSHD and VSHA first. then VCC. then VSS, then VEE

*then VDD.

Turn off --- VDD first, then VEE, then VSS, then VCC, then VSHD and VSHA

(b) The input signal of “‘MOD” Terminal(Pin No.3) must be LOW level 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, give it

HIGH level voltage until power off.

vote 7-l]These are standard input voltages for gray scale. When VCOM is alternated polarity, these

voltage should bc altcmated polarity. VO(black) is different polarity alternating signal of

VCOM. V9(white) is the same polarity alternating signal of VCOM. Center voltage of each

standard input voltage shift positive way for LCD characteristics (namely VO shifts positive first,

then VI, then V2, then V3, then V4, then V5, then V6, then V7, then VS, and then V9).

This sift amount is adjusted so as to no flicker

of each standard input voltage after DC bias voltage of VCOM and VO is adjusted.

mote 7-21 It must be kept that 3.OV 5 (VCC-VSS) < 3.6V.

0 must be held high voltage until turning off the power supply. (Connect Pin No.3 and No.4 terminals to the same

signal.)

[Note 7-3]The same phase and amplitude with VCOM. VEEDC is center of VEE.

[Note 7-4]DCLK,SPL,SPR,LBR,LP,PS,RO-RS,GO-G5 and BO-B5 terminals are applied.

[Note 7-S]DCLK,SPL,SPR,LBR,LP,RO-RS,GO-G5 and BO-B5 terminals are applied.

mote 7-6]PS terminal is applied.
