Make the display fit your product.
Bring your requirements. We will review the configuration with you.
Pin row
The pins run along the top edge, bent towards the rear with a 12.0 ± 0.50 mm length. Pin count and pitch are confirmed with the project drawing.
03 / APPLICATION DIRECTION
Audio equipment displays
The source application is audio equipment displays. Band, unit and status legends are fixed artwork; tuning and reception are handled by the audio electronics.
ENGINEERING NOTES
What the specification means for your design.
How S3646D 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 →
Digits and icons
Digit, decimal point and icon layout set the segment count and pin map. 7-segment digit design →

04 / PRODUCT SUPPORT
From reference to your design.
Why are pin count and pitch not listed?
The pitch note on the source drawing is not consistent, so both values are withheld here and confirmed during the project review.
Does the LCD include a radio tuner?
No. It is a display reference; tuning, reception and audio processing are separate electronics.
