12 TEMPERATURE COMPENSATION
Due to the temperature dependency of the liquid crystal viscosity, the LCD controlling voltage V
with lower temperature to maintain optimum contrast. Figure 14. shows V
temperature coefficient of V
13 LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); see notes 1 and 2.
Notes
1. Stresses above those listed under Limiting Values may cause permanent damage to the device.
2. Parameters are valid over operating temperature range unless otherwise specified. All voltages are referenced to
14 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices (see “Handling MOS devices” ).
