Customized TN LCD Segment Screen Transmissive White Backlight 4.5V 24PIN
A TN segment LCD (Twisted Nematic Segment Liquid Crystal Display) is a type of passive matrix LCD technology that is custom-made with fixed segments, commonly used in simple, low-cost electronic displays.
How It Works
-
Segments are created in fixed patterns (e.g., 7-segment digits, battery icons, arrows).
-
Liquid crystals twist under an applied voltage, allowing or blocking light through polarized filters.
-
Only the predefined segments can be turned ON or OFF—no pixel-level control like dot-matrix displays.
Interface
-
Typically driven by direct drive (if few segments) or multiplexed drive (for many segments).
-
Driven by microcontrollers or LCD driver ICs like:
-
HT1621 (for multiplexed)
-
PCF8576, ST7032, etc.
-
-
Signals: Common (COM) and Segment (SEG) lines.
