Early Foundations — The Birth of Liquid Crystal Technology

The origins of LCD technology date back to the late 19th century when Austrian botanist Friedrich Reinitzer discovered liquid crystals. This early research laid the groundwork for a century of innovation. By the 1960s, scientists began experimenting with liquid crystals to manipulate light, which eventually gave birth to the first practical liquid crystal display.

The early LCDs were primitive compared to today’s high-resolution screens, but they presented an exciting alternative to CRT (cathode-ray tube) displays. They were lighter, consumed less power, and offered the potential for thin, compact designs.

1970s–1990s: From Prototype to Commercial Success

The 1970s marked the commercialization of LCD screens, beginning with simple digital displays used in calculators and watches. Several milestone technologies emerged during this period:

TN (Twisted Nematic) LCDs, providing low power consumption

STN (Super Twisted Nematic), offering better contrast

Passive matrix LCDs, which were affordable and widely used

While these early display types were limited in color and viewing angles, they paved the way for more sophisticated technologies.

By the 1990s, TFT (Thin-Film Transistor) LCDs revolutionized the industry. TFT LCDs allowed precise control of each pixel, delivering higher resolution, richer color, and faster response times. This breakthrough led to LCD screens replacing CRTs in nearly every major market.
