The optimum values for above-mentioned Cl, C2 and
C3 vary according to the LCD panel to drive. Use the
above-mentioned values as references. Actually verify
the display of a pattern with big load to make a decision.
6.6.4 Temperature gradient select circuit
This is a circuit to select the temperature gradient
characteristics of the liquid crystal drive power supply
voltage. Temperature gradient characteristics can be
selected from eight states by the Temperature Gradient
command. Selection of temperature gradient
characteristics conforming to the temperature
characteristics of the liquid crystal to be used makes it
possible to configure a system without providing an
external element for temperature characteristics
compensation.

26. Discharge : ON (only for when RES = LOW)
27. Power save : OFF
28. Temperature gradient resistor : (D2, D1, D0) = (0,
0, 0) (–0.06/
°
C)
29. Register data in the serial interface : Clear
When the Reset command is used, only the above-
mentioned inilialized items 7, 8 and 19 are executed.
When power is turned on, initialization by the RES pin
is necessary. After initialization by the RES pin, each
input pin must be controlled correctly.
Furthermore, when control signals from the MPU have
a high impedance, the excessive current may flow to the
IC.
After V
DD
is applied, measures should be taken to
ensure that the input pin does not have a high impedance.
The S1D15E06 series discharges the electric charge of

and liquid crystal drive voltage (V

) at the level of RES pin = LOW. When
liquid crystal drive external power supply is used,
external power supply should not be supplied during the
period of RES = LOW to prevent external power supply
and V
DD
from being short circuited.
*5 Precautions when installing the COG
When installing the COG, it is necessary to duly consider
the fact that there exists a resistance of the ITO wiring
occurring between the driver chip and the externally
connected parts (such as capacitors and resistors). By
the influence of this resistance, non-conformity may
occur with the indications on the liquid crystal display.
When installing the COG, we recommend to use the "

External power supply only"
