13.0 PRECAUTIONS

13.1 Static charge

Since this LCD module contains CMOS LSIs that are sensitive to static charge, care must be

taken when handling it.

13.2 Power on sequence

1. Input signals should not be applied to the LCD module before the logic system voltage has

reached the specified voltage. If the above sequence is not kept the LCD module might be

permanently damaged.

2. When connecting the power supply, connect the LCD bias voltage after connecting the logic

system voltage.

3. When disconnecting the power supply, disconnect the logic system voltage after the LCD bias

voltage.

4. It is recommended to connect a serial resistor or fuse to the LCD bias power supply of the

system, as a current limiter. The value of the resistor depends on the kind of LCD used, but is

typically 50 ~ 100 Ω .

13.3 Operation

1. It is essential to drive the LCD within the specified voltage limits, since a higher driving

voltage than allowed causes a shorter LCD lifetime. Under these circumstances,

electrochemical reactions will result in undesirable deterioration of the LCD.

2. The response time of the LC fluid is considerably longer at low temperatures than in the

normal operating temperature range. On the other hand, the LCD will show a dark blue color

at high temperatures. Those phenomena do not indicate a malfunction or defect of the LCD.

Back at normal temperatures, the LCD will return to its original behavior.

3. If the display area is pressed hard during operation, some abnormal display patterns might

appear. However, the display will resume normal operation after turning the module off and

on.

4. Moisture on the terminals could cause an electrochemical reaction resulting in an open

terminal connection. If the environmental temperature is higher than 40℃, it is required that

the relative humidity is 50% or less.

13.4 Packaging

1. Do not leave the product in a place of high humidity for a long period. For storage in a

location where the temperature is 35℃ or higher, special care to protect the product from high

humidity is required. A combination of high temperature and high humidity may cause

polarization degradation and damage as well. Please keep the temperature and humidity

within the specified range for storing.
