The Era of Miniature Screens
The very first television prototypes were a far cry from the large screens we enjoy today.
These early televisions, developed in the 1920s and 1930s, used mechanical systems with rotating discs or mirrors to create an image on a tiny screen.
The image quality was crude and blurry, but it was a revolutionary technology at the time.
A notable example is the Octagon, made by General Electric in 1928.
This mechanical television had a screen size of only 3 inches in diameter, which limited the viewing experience to a small audience.
Early Electronic Televisions
Electronic TVs offered a welcome improvement over their mechanical predecessors, but screen sizes remained relatively small by modern standards.
Early electronic televisions, which became commercially available in the 1940s, typically had screens ranging from 5 to 12 inches diagonally.
Basically, these TVs were a marvel of engineering, but their high cost limited their widespread adoption.
Only the most affluent families could afford the luxury of owning a television, and even for those who could, the small screen size meant that viewing was often a social experience, as there simply wasn’t enough space on the screen for everyone to see the picture comfortably.
Despite the limitations, these early electronic TVs laid the foundation for the television revolution that would unfold in the decades to come.
The CRT Era and Its Limitations
Cathode ray tubes (CRTs) dominated television technology for decades.
CRTs used a bulky electron gun to fire a beam of electrons at the screen, which produced the picture.
The size of the electron gun and the deflection system limited how large CRT screens could become.
While screens did get modestly bigger by the 1970s (25-inch sets were considered large), a 32-inch CRT TV was very heavy and required substantial furniture to support it.
The curvature of the screen was another limitation of CRT technology, making it difficult to achieve a truly immersive viewing experience.
The Flat-Panel Revolution
LCD and Plasma technologies were game-changers!
They both revolutionized the television industry by introducing large, thin, and lightweight screens.
Unlike CRTs, which required bulky picture tubes, LCD and Plasma TVs used flat panels that could be much larger without becoming unwieldy.
This basically opened the door to a new era of home entertainment, where we could enjoy movies and shows on expansive screens that delivered a more immersive and cinematic experience.
The affordability of these flat-panel TVs also played a significant role in their widespread adoption.
