3.3V-5V 7 Segment TN LCD Display Blue Backlight HT1621 COB Module
Segment LCD Display TN LCD Display Blue Backlight HT1621 COB Module
Twisted Nematic (TN) Technology
- TN LCDs use liquid crystal molecules that are twisted when no voltage is applied. This twist helps control light passage through the display.
- When voltage is applied, crystals untwist, allowing controlled light passage to display pixels or segments.
- TN displays utilize polarizers and backlight for illumination as crystals don't emit light.
Display Types
- Used for monochrome or RGB (color) displays depending on application.
- Common in segment-based displays (digital clocks, readouts) and full-screen displays (monitors, TVs, smartphones).
