Reflective viewing
The rear polarizer is reflective, so the reference is read with ambient light. It uses 1/4 duty, 1/3 bias at 3.0 V and 64 Hz, 6 o'clock viewing direction.

Multimedia player displays
The source application is multimedia player displays. Source and playback legends are fixed artwork; media decoding and storage handling belong to the player electronics.
ENGINEERING NOTES
What the specification means for your design.
How S3457D 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 →
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.
Why is the pin pitch not listed?
The pitch note on the source drawing is not consistent with the numbered pins, so it is withheld here and confirmed during the project review.
Is a backlight required?
The reflective rear polarizer is intended for ambient-light reading. A backlit version would be a different optical configuration.
