Tire-pressure displays
An OEM display reference for tire-pressure equipment. The artwork provides pressure, temperature and warning fields; it does not establish a pressure sensor, wireless receiver or measurement accuracy.
ENGINEERING NOTES
What the specification means for your design.
How S3437D relates to LCD mode, drive, connection and integration choices, with links to the SuccessLCD engineering guides.
DFSTN LCD mode, negative
Double-film STN: two compensation films give high contrast, here with a dark background and backlit segments. Compare TN, HTN, STN, FSTN, DFSTN and VA →
Drive: 1/8 duty, 1/4 bias
8 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 →
Negative display
A negative LCD needs a backlight; the look is close to a VFD or LED readout. VFD vs LCD →
