02 / OEM DESIGN
Make the display fit your product.
Bring your requirements. We will review the configuration with you.
Reflective viewing
A reflective rear polarizer is listed. Review readability under the expected ambient lighting and the 6 o’clock viewing direction.
Measurement fields
Confirm the units and labels your scale uses before finalizing the segment mapping.
03 / APPLICATION DIRECTION
Body fat scales
Use this reference to plan measurement, user and body-composition indications on a personal scale. Confirm the displayed quantities and validate the complete scale for its operating environment.
04 / PRODUCT SUPPORT
From reference to your design.
Which drive settings are listed for S3689D?
The reference lists 3.0 V LCD operating voltage, 1/5 duty, 1/3 bias and 64 Hz frame frequency. Check them against your LCD driver; final electrical requirements are confirmed for the project.
Does S3689D use metal pins?
No. The reference uses contacts on the glass for a heat-seal connection rather than metal pins.
