Notes on Power-On/Off of the LCD Driver
To prevent an LCD driver display error at power on/off, the sequence for power-on signal activation must
be as follows (see figure 10):
2.7V
V
CC
VLCD
DISP
0ms
0ms
0ms
0ms
2.7V
Input signals such as
CL1, CL2, and Data
Signal non-fixed
period
Initializing period
(1frame or longer)
Figure 10 Sequence of Power-On/Off
At Power On
(1) Power on V
CC
. At this time, input 0 to the
DISP
pin.
(2) Display-off function forces the LCD driver to output a V2 level (lowest level).
(3) Display-off function takes priority even if the input signal status becomes irregular immediately after
V
CC
power-on.
(4) Input the specified signals to initialize registers of the LCD driver. Its period must be 1 frame or longer.
(5) Set the
DISP
level to 1 to cancel display-off function after steps (1) to (4). At this time, VLCD and each
V pin input must be at the specified levels.
