Make the display fit your product.
Bring your requirements. We will review the configuration with you.
Mechanical integration
Plan the housing around the compact glass and edge contacts. Keep the 24.80 × 24.80 mm minimum viewing area clear.
03 / APPLICATION DIRECTION
Timer and alarm-clock displays
The source application is timer and alarm-clock displays. The shown symbols are fixed LCD artwork; sensing, calculations and control functions are specified in the complete device.
ENGINEERING NOTES
What the specification means for your design.
How S4004D relates to LCD mode, drive, connection and integration choices, with links to the SuccessLCD engineering guides.
HTN LCD mode, negative
High twisted nematic glass: better contrast and a wider viewing angle than TN at a similar cost. Negative mode shows bright segments on a dark background with a backlight. 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: zebra connector
An elastomeric connector presses the glass contacts against PCB pads; the housing or a bracket provides the clamping force. LCD connection types →
Negative display
A negative LCD needs a backlight; the look is close to a VFD or LED readout. VFD vs LCD →
