02 / OEM DESIGN
Make the display fit your product.
Bring your requirements. We will review the configuration with you.
Pin connection
Review the upper pin row and its 2.54 mm pitch against the PCB. Confirm the segment assignments and assembly clearance.
Transflective viewing
Evaluate the positive, transflective display under the intended ambient light and illumination, using the listed 12 o’clock viewing direction.
03 / APPLICATION DIRECTION
Temperature controllers
Use this reference to plan a controller panel that presents measured and target humidity alongside temperature. Confirm the required language, units and indication groups with the control design.
04 / PRODUCT SUPPORT
From reference to your design.
Which LCD drive settings are listed for S3439D?
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 artwork define humidity or temperature accuracy?
The artwork defines display fields and symbols. Measurement accuracy, sensing components and controller functions must be specified separately for the finished product.
