1. When using an access lcd module and disconnect the power supply must be (5 ± 0.25V) to the input signal level at the positive.
2. The dot matrix modules are high large ones lcd display a great contrast, viewing angle and temperature, drive voltage relationship.
3. When the specified operating temperature range limit use, displays the response is very slow. In the specified operating temperature range of the upper limit using the entire display surface becomes black, this is not damaged, the recovery temperature range, can return to normal.
4. Firmly press the display section, will produce abnormal display, just turn off the power, re-access can be restored.
