History of Computer Display: From Teletype to Touch Screen

A breakthrough in computer technology was possible after the invention of display mechanism. The earliest display mechanism in computers was early Teletype Monitor. Computers and televisions that we know today became a reality after the invention of Cathode Ray Tube (CRT). CRT was the only display mechanism for computers and TVs until recently.

Computer Display can be broken down to

  • The Early Teletype Monitor
  • Cathode Ray Tube (CRT) Displays
  • Liquid Crystal Displays (LCD)
  • Plasma Displays
  • Light-Emitting Diode (LED)
  • 3D Monitor
  • Touch Screen

In this series of computer display, we have already discussed on

Early Teletype Monitor and Cathode Ray Tube

LCD and Plasma Display

On this article we will focus on Light-Emitting Diode (LED), 3D Monitor and Touch Screen.

Light-Emitting Diode (LED)

Technological advancement in Computer Displays has led to invention of LED monitors. Today, LED displays, used both in computer monitor and Television screen, are in vogue. LED provides higher contrast and better viewing angles compared to LCD.

3D Monitor

In the last couple of years advancement in Computer Displays has taken a giant leap. Now monitors are able to deliver three dimension visuals. The Polarized 3D Monitor displays flicker free 3D images when viewed through polarized glasses. Autostereoscopic screen generates 3D images without headgear.

Touch Screen

Touch Screen Displays are the latest invention, which uses touching of the screen as an input commands. Touch Screen technology is widely used in hand-held devices such as cell phone and tablet. Though not so popular because of their high price, Touch Screen technology is also used in desktop monitors and laptops.

In the beginning computer monitors were used for data processing and television receivers for entertainment. Today the lines between computer monitor and TV have blurred because TV sets have become fully digital. We can now use high-definition TV as a computer.

How Computer Display Helped in the Evolution of Computer Graphics

In the last 80 years or so, computer graphics and computer display have made phenomenal advancements. Evolution of Computer Graphics is closely related to the advancement of Computer Display.

The history of computer graphics can be traced to the invention of the thermionic valve or electron tube. The thermionic valve or electron tube made possible to generate black and white images. Later, the technology improved, and color images in computer and television screens became possible.

By the 1980s, personal computers such as Commodore Amiga and Macintosh were developing as a design tool. In the late 1980s, the first fully computer-generated short films were developed at Pixar by using SGI computers.

Today, Computer Graphics are extensively used in the field of education, and science and technology. Computer-aided design, computer simulation, digital art, graphic design, animation, video games, virtual reality and web design are some of the field that make wide use of Computer Graphics. These days, many advanced computer software are available in the market that help people to create animations or cartoon movies.

    My first job was a computer programmer trainee. We were using the IBM punched cards for our bank’s mainframe computer which was an IBM S/370. The computer monitor was a teletype which is like an electric typewriter. That is the only communication system of the operator with the CPU that was as large as a refrigerator. The IBM 1403 printer was also huge which uses a continuous form that can print 132 characters in one line. Pardon me for reminiscing the good old days when the magnetic tape drive was like a washing machine with tape reels that were large as well.

      I used a computer for the first time when I was a ninth grader, that was back in the 1990s. It had a black and white monitor and uses floppy disks for flash storage.

    Thanks for the simple, but to the point explanation. Agree with you devices have become much smaller, screen resolution and color depth are beyond anything that people would have imagined in 80’s.

    I just bought a Dell XPS 18 as a AiO/Desktop replacement?massive tablet and love it. I got one refurbished for a very sensible price. Obvioulsy, that is not what Dave is looking for but for but other folks this could well be anoption.
    I looked at the Lenovo Horizon but with £1300 it is just too pricey.
