Key Concepts of HTN Blue LCD
HTN (High-Twist Nematic) Technology
- HTN is a variation of the Twisted Nematic (TN) LCD technology with more highly twisted liquid crystal molecules for higher contrast ratio and better readability.
- Provides improved viewing angles compared to regular TN technology, though still limited compared to IPS (In-Plane Switching).
Blue Color
- Blue refers to the backlight color or color of segments when lit, providing bright, vibrant contrast to darker backgrounds.
- May use blue or cyan-colored characters on dark background or blue LED backlight.
LCD Structure
- HTN LCDs use either positive or negative display modes.
- In negative mode (as in this product), background is dark with bright segments.
- Can feature blue backlight with blue text/segments or dark background with illuminated blue segments.
