OEM DISPLAY REFERENCE
S3689D is a TN, positive-mode segmented LCD reference for a body fat scale. The artwork combines a main reading with cm, kg, year and % units, a secondary reading, a KCAL field, user and BMI labels and a body-shape indicator.
Images, 3D geometry and listed parameters are OEM reference information. Final dimensions, electrical requirements, optical configuration and construction are confirmed for your project.

02 / OEM DESIGN
Bring your requirements. We will review the configuration with you.
The glass carries 31 contacts at 2.00 mm pitch for a heat-seal connection. Confirm the connector and bonding area with the PCB design.
A reflective rear polarizer is listed. Review readability under the expected ambient lighting and the 6 o’clock viewing direction.
Confirm the units and labels your scale uses before finalizing the segment mapping.
03 / APPLICATION DIRECTION
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
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.
No. The reference uses contacts on the glass for a heat-seal connection rather than metal pins.
