Appendix I Instruction Setup: (For reference)
This section discuss on the initialization, write display data and power off routines of the SSD181X/SSD1815A/SSD1815B.
When the power is applied, the VL5 to VL2 levels are non-selected. The non-selective levels are output through the LCD driv-
ing output pins, i.e., Segment and Common. The residual electric charge of the stabilizing capacitors, which is connected
across the VL6 ~ VL2 levels and Vdd, may induce back into the device. As a result, the LCD panel display totally black instan-
taneously during the power is turning on. We recommended the following power up sequence in order to prevent the unex-
pected flashing on the display.
Instruction routine: Normal procedure
Case 1 –The built-in power is used immediately after turning on the power supply
Initialization routine start
/RES pin is set to "Low " when the pow er across VDD-VSS is turned on
/RES pin is set to "High" after the pow er across VDD-VSS is stable
Set LCD bias
Set Segment Re-map
Set COM Output Scan Direction
Set Internal Regulator Resistor Ratio
Set Contrast Control Register
Set Pow er Control Register
LCD Pow er Levels
are not stable
LCD Pow er levels are stable
Initialization routine end
Remarks: Initialization routine lasts for 5 ms. The estimated time 5 ms vary depending on the panel characteristics
and the capacitance of stabilizing capacitors. Please ensure a proper operation check is performed by actual
equipment.
