History of Computer Monitor Design: From CRT to OLED


Computer monitors have come a long way since the first CRT displays were introduced in the late 1960s. With the advent of LCD and OLED technology, computer monitors have become slimmer, more vibrant, and more energy-efficient. In this article, we’ll take a journey through the history of computer monitor design, from the early days of CRT to the modern era of OLED.

Early Days of Computer Monitor Design

In the early days of computer monitors, the only display technology available was the Cathode Ray Tube (CRT). These monitors were bulky and heavy, with thick glass screens and a limited range of resolution options. However, they were the only option available, and so they were widely used in the early days of computing.

The Rise of Flat-Screen Monitors

In the late 1990s, the first flat-screen monitors started to appear on the market. These monitors used Liquid Crystal Display (LCD) technology, which allowed for much thinner screens and higher resolution displays. This technology quickly replaced CRT as the go-to display technology for computer monitors.

The Introduction of LED Monitors

The next major advancement in monitor technology came in the form of Light-Emitting Diode (LED) monitors. These monitors used LED backlighting instead of traditional CCFL backlighting, which allowed for even thinner and more energy-efficient displays. LED monitors quickly became the industry standard, and remain so to this day.

The Emergence of OLED Monitors

The most recent advancement in monitor technology is Organic Light-Emitting Diode (OLED) displays. These monitors use organic materials to produce light, which allows for even thinner screens and more vibrant colors than LED monitors. OLED monitors are still relatively expensive compared to other display types, but are gaining popularity among high-end users who demand the best visual experience.

Evolution of Monitor Resolutions

As computer monitors have evolved, so too have their resolution options. The first computer monitors had a maximum resolution of 640×480, which was considered high-resolution at the time. Today, monitors are available with resolutions as high as 8K, which is 16 times the resolution of 1080p.

Aspect Ratios of Monitors

In addition to resolution, computer monitors have also evolved in terms of aspect ratio. The first computer monitors had a 4:3 aspect ratio, which was common for many years. In recent years, however, widescreen monitors with a 16:9 aspect ratio have become more common, and some ultra-wide monitors even have a 21:9 aspect ratio.

Curved Monitors

Another recent trend in monitor design is the curved display. Curved monitors are designed to provide a more immersive viewing experience by wrapping the screen around the user’s field of vision. While not everyone likes the curved design, it has become popular among gamers and others who demand an immersive visual experience.

The Future of Monitor Design

Looking to the future, it’s clear that monitor technology will continue to evolve. Some experts predict that flexible displays will become the norm, allowing users to roll up their screens like a piece of paper. Others believe that augmented reality displays will become more common, allowing users to interact with virtual objects in the real world.


  1. What is the oldest type of computer monitor? The oldest type of computer monitor is the Cathode Ray Tube (CRT) display.
  2. What is the highest resolution available on a computer monitor? The highest resolution currently available on a computer monitor is 8K.
  3. What is the most common aspect ratio for modern computer monitors? The most common aspect ratio for modern computer monitors is 16:9, which is a widescreen aspect ratio.
  4. What is the difference between LED and OLED monitors? LED monitors use LED backlighting to produce light, while OLED monitors use organic materials to produce light. OLED monitors are thinner and have more vibrant colors than LED monitors, but are also more expensive.
  5. What is the advantage of a curved monitor? Curved monitors provide a more immersive viewing experience by wrapping the screen around the user’s field of vision, which can be beneficial for gamers and others who want a more immersive visual experience.


From the bulky CRT displays of the past to the sleek OLED monitors of today, the history of computer monitor design is one of constant innovation and improvement. As technology continues to advance, we can expect even more exciting developments in the world of monitor design. Whether it’s flexible displays, augmented reality screens, or something else entirely, the future of monitor design is sure to be bright. So if you’re in the market for a new monitor, be sure to stay up-to-date on the latest advancements in technology – you never know what the next big thing might be!
