Please The Check Busy method of S1D13700 is checking the “WAIT” pin directly.ᇭ Newhaven Display International Page 9 of 18 NHD-320240-WG-BxFMI-VZ# (2) Owing to S1D13700 having 32K*8 SRAM inside, so It doesn’t need to set the bit “M1” in “SYSTEM SET”. For S1D13700, we doesn’t set M1 (bit1)᧨the setting for SED 1335 is shown as below: The setting of S1D13700 will show as follow: Newhaven Display International Page 10 of 18 NHD-320240-WG - B x F M I - V Z # 10.RELIABILITY Content of Reliability Test (wide temperature, -20ഒ~70ഒ) Environmental Test Test Item Content of Test Test Condition Endurance test applying the high storage temperature for a 80ഒ long time. 200hrs Low Temperature Endurance test applying the high storage temperature for a -30ഒ storage long time. 200hrs High Temperature Endurance test applying the electric stress (Voltage & 70ഒ Operation Current) and the thermal stress to the element for a long time. 200hrs Low Temperature Endurance test applying the electric stress under low -20ഒ Operation temperature for a long time. 200hrs High Temperature storage Note 2 1,2 —— 1 The module should be allowed to stand at 60ഒ,90%RH max 60ഒ,90%RH High Temperature/ For 96hrs under no-load condition excluding the polarizer, 1,2 Humidity Operation 96hrs Then taking it out and drying it at normal temperature.
