The world of television has undergone a significant transformation over the years, from the bulky big box TVs of the past to the sleek, slim designs of today. But have you ever wondered what those big box TVs were called? In this article, we’ll delve into the history of big box TVs, explore the different types of technology used, and discuss the evolution of TVs over time.
A Brief History of Big Box TVs
Big box TVs, also known as CRT (Cathode Ray Tube) TVs, were the norm in the television industry for several decades. The first CRT TV was invented in the late 1920s by Philo Farnsworth, an American inventor and television pioneer. CRT TVs used a cathode ray tube to display images on the screen, which was made up of a large glass tube filled with a gas, typically argon or nitrogen.
The CRT TV was a significant innovation in the world of television, offering better picture quality and a more immersive viewing experience than its predecessors. However, CRT TVs were also bulky, heavy, and prone to overheating, which made them difficult to handle and maintain.
The Anatomy of a CRT TV
A CRT TV consists of several key components, including:
- The cathode ray tube (CRT), which is the heart of the TV
- The electron gun, which produces the electrons that create the images on the screen
- The phosphor coating, which converts the electrons into visible light
- The shadow mask, which helps to focus the electrons onto the phosphor coating
- The deflection system, which controls the movement of the electrons across the screen
These components work together to create the images that appear on the screen, using a combination of electrical and magnetic fields to control the flow of electrons.
The Rise of Flat-Screen TVs
In the late 1990s and early 2000s, flat-screen TVs began to emerge as a viable alternative to CRT TVs. Flat-screen TVs use a different technology to display images, such as plasma or LCD (liquid crystal display). These TVs are thinner, lighter, and more energy-efficient than CRT TVs, making them a popular choice for consumers.
Plasma TVs use individual cells filled with a gas, such as neon or xenon, to display images. Each cell is electrically charged to create a plasma, which emits light when excited by an electrical current. LCD TVs, on the other hand, use a layer of liquid crystals to block or allow light to pass through a matrix of pixels.
The Benefits of Flat-Screen TVs
Flat-screen TVs offer several benefits over CRT TVs, including:
- Thinner and lighter designs, making them easier to handle and install
- Improved energy efficiency, reducing power consumption and heat generation
- Wider viewing angles, allowing for a more immersive viewing experience
- Higher contrast ratios, resulting in deeper blacks and brighter whites
However, flat-screen TVs also have some limitations, such as lower brightness levels and limited color gamut.
