Remarks<br />
Note :<br />
1. Please avoid floating state of interface signal at invalid period.<br />
2. When the power supply for LCD (VLCD) is off, be sure to pull down the valid and invalid data to 0V.<br />
3. The T3 / T4 is recommended value, the case when failed to meet a minimum specification,<br />
abnormal display would be shown. There is no reliability problem.<br />
4. If the on time of signals (Interface signal and user control signals) precedes the on time of Power (VLCD),<br />
it will be happened abnormal display. When T6 is NC status, T6 doesn’t need to be measured.<br />
5. T5 should be measured after the Module has been fully discharged between power off and on<br />
period.<br />
6. It is recommendation specification that T8 has to be 100ms as a minimum value.<br />
