ENGINEERING NOTES
What the specification means for your design.
How S3915D relates to LCD mode, drive, connection and integration choices, with links to the SuccessLCD engineering guides.
HTN LCD mode
High twisted nematic glass: better contrast and a wider viewing angle than TN at a similar cost. Compare TN, HTN, STN, FSTN, DFSTN and VA →
Drive: 1/4 duty, 1/3 bias
4 common electrodes share the segment lines. Set the controller to the duty, bias, voltage and frame frequency on the drawing. Duty and bias explained →
Connection: metal pins
Metal pins are soldered into the PCB, the most robust connection for segment glass. LCD connection types →
Transflective polarizer
Readable by daylight and with a backlight in the dark. Transflective LCD display →
