The Origins Of Our Lcd Screens And High Definition Plasma TVs In Vintage Computer Monitors
This might be amazing for computer users today who are familiar with small compact LCD monitors. Not only is the computer monitor large and complicated but the initial monitor used by computer enthusiasts was the colorless Cathode Ray Monitor,
Early vintage monitors were monochrome single colors instead of the brilliant color display that we received today.
Some of these monochrome monitors are green or orange. Others are similar to gray and black and white television sets.
Now it’s taken for granted by young surfers and computer gamers that television is always in color, not so.
Initially the TV broadcast was in black and white.
Color TVs have been developed but the technology but widespread use did not emerge until the early 1970s and even later in some areas.
Broadcasts are seen as black and white in the set and colors in the color set.
Color TVs can also receive programs that are in black and white mode. A kind of backwards compatibility today.
So what is the difference between the picture quality of a television set that has a monitor that has a much greater resolution than a standard TV set.
Time TV sets (as opposed to current high-end LCDs and high definition plasma TVs) are basically 1950s technology and even newer color TVs. .
The monitor screen display must be stable and of good quality, because computer users can sit very close to the monitor and spend hours reading the display.
If the image is blurred (low resolution) or is wavering constantly, you will experience throbbing headaches and wavering eyes in a short amount of time.
The monitor has buttons for adjusting clarity. On vintage monochrome monitors this usually includes a brightness knob that adjusts the lighting of the entire screen, and a contrast knob that makes letters lighter or darker in relation to a newer color monitor background screen will have additional adjustments to color.
The question that will arise is how the vintage CRT (Cathode Ray Tube) monitor initially handled color technology that came later and became an accepted standard.
A typical color monitor works the same way as a standard CRT television.
The inside of the drawing tube is coated with three different phosphors: red, green and blue.
Phosphorus is a special chemical compound that glows with distinctive colors when it rains on the flow of electrons.
Phosphorus gets excited and thanks to the additive properties of the color wheel, different color lights produce blends and all kinds of combinations of the three primary colors are produced.
The end result is that almost all the colors of the rainbow can be produced.
And for the white color of the eyes play a useful trick. When all three colors are mixed together in equal amounts, the eye sees it as white light.
Finally, the sharpness of a CRT color monitor or TV picture is determined by three factors: the monitor’s bandwidth, its dot pitch, and the accuracy of its convergence.
Although bandwidth and dot pitch are important for determining a good monitor, convergence is the true measure.
Indeed we have been far from the earliest simple vintage monochrome monitors. What we now receive with LCD monitors and indeed our high definition TV sets all come with simple CRT monochrome monitor technology combined with technology and tricks obtained from the color TV industry.
We all must be grateful. We owe a lot to “Uncle Miltie”.
