History of Monitors
A monitor is an electronic visual display for computers. In the early stages of the monitor’s evolution there were known as Terminals. Computer monitors were originally used for data processing and televisions were used for entertainment. Computers and their monitors have been used for data processing and entertainment since the 1980s. In 1981 IBM launched its first computer. It was known as a ‘three piece computer.’ The three different units were CPU, monitor and keyboard separately. To learn more about the history of various types of monitors, visit this website.
Types of Monitors
- "LCD (liquid crystal display)": flat panel monitor; light and energy efficient
- use pixels; composed of three subpixels (red, blue, green) and some newer ones have added yellow pixels
- Quality depends on the aspect ratio. The resolution can change depending on the actual size of the screen
- "LED (light-emitting diode)": more energy efficient; might have better color accuracy
- "OLED (Organic light-emitting diode)": produce light when exposed to an electric current. Do not require a back-light to function, so they draw less power and have a thinner display.
- "CRT (cathode ray tube)": no longer popular screen type; a type of "legacy technology"
Computer monitors can be used in technology to display basic computer information. They can be used for anything the computer can be used for. Common uses for computer monitors include:
- PC Gaming
- TV or live sports streaming
- Screen for laptops
Larger panels increase the number of pixels that you can display. Most newer monitors have 1920x1080 resolution, which is used to play Blu-Ray movies. If the screen is too large, paired with a low resolution, the picture or video quality of whatever you are viewing will be low.
Price ranges for computers can vary highly depending on size, resolution, type, and refresh rate. OLEDs and touchscreen monitors seem to be on the higher end of the price range. On the other hand, LCDs can be much cheaper than the others. Some of the cheaper computers found were around $10 to an outrageous $23,000!
