COG Segment LCD Display TN Negative 20pin FPC RGB Color Backlight For Stopwatch

Negative Image (Negative Display):

• In a negative TN LCD, the liquid crystals are aligned in such a way that when no voltage is applied, the light passes through the crystals and the pixels appear dark (black or dark gray).
• When voltage is applied to a pixel, the crystals twist to allow light to pass through, making that segment or pixel appear light (white or light gray) on the dark background.
• This negative display typically results in a light background (often white) and dark segments or text, which is the opposite of how most common "positive" displays work (with dark background and light segments).
