02 / OEM DESIGN
Make the display fit your product.
Bring your requirements. We will review the configuration with you.
Driver matching
Match the LCD operating voltage, duty and bias to the segment driver and confirm the pin assignment.
Electrical requirements
Confirm your host controller, supply, drive method and backlight requirements before sampling.
03 / APPLICATION DIRECTION
Remote controls
The source application is remote controls. The visible CM legend and numeric fields describe the artwork; they do not establish a distance sensor or ranging function.
ENGINEERING NOTES
What the specification means for your design.
How S3719D relates to LCD mode, drive, connection and integration choices, with links to the SuccessLCD engineering guides.
FSTN LCD mode
Film-compensated STN: a retardation film gives a near black-on-white look with higher contrast. 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 →
Reflective polarizer
Readable by ambient light without a backlight, for the lowest power. Reflective vs transflective LCDs →

04 / PRODUCT SUPPORT
From reference to your design.
Which LCD drive settings are listed for S3719D?
The reference lists 3.0 V LCD operating voltage and 1/4 duty, 1/3 bias, at 64 Hz frame frequency. Check these requirements against your LCD driver; final electrical requirements are confirmed for the project.
Does the CM legend mean a distance sensor is included?
No. The legend is part of the display artwork. This LCD reference does not include or specify a distance sensor.
