Once the computers did not have screens, and the output was on a piece of paper or with signals, but once left - ten years ago you had to read it from a gray box with a round screen and a terrible resolution. Will you please give me ten inches?
Since the introduction of the electronic computer, the need to present user interaction results through visual output has also been created. Otherwise, what's the point of doing calculations with it if you can not see the results? This will be just as useless as solving a complicated problem, just in order to throw the page with the solution to shred immediately afterwards.
- This article is part of a project Summary of the decade according to HWzone
The computers of the "ancient world" were known as units ECM (MT Electronic Computing Machine) Which did not contain any port Video And they used creative solutions to present the results of the calculation to the computer operator: The first solution came in the form of a very long roll of paper in which holes were pierced. Thereafter, further attempts were made to display the printed output, this time using printer, But this method was not particularly successful either. Then the screen was replaced by incandescent bulbs that turned on and off according to preset patterns. This method supported the presentation of various outputs dynamically, but was fixed to the same patterns can not be changed.

First appearance of screens CRT
After all the failed attempts,CRT, The first screens we can recognize as ordinary computer screens. These screens use an electron cannon and a surface coated with phosphorus. Light was distributed as a result of the electrons' exposure to the phosphorescence surface, creating a picture. ScreensCRT The first ones were very low resolution and showed only one color. If this is not enough, because of high production costs, the screens were very small and their size ranged around the 10 inch.
As the technology progresses,CRT Display a black and white picture and finally even a color image. At this stage we first met the term "screen saver". Today, screen savers are nothing more than office decoration, but once their name really reflects their purpose. As a result of continuous and continuous damage of electrons at one point on the screen, the phosphorus material would continue to produce light even when the screen was turned off. This caused the shadow effect of an image burned on the screen.
|It was once considered progress|
At that time,CRT Will last forever. The image became sharper, the dimensions of the screens only grew and in the late nineties the company Sony Even managed to flatten the curved screens and claimed that finally a perfect picture can be displayed on the screen, one that is not distorted by the curve. The competing companies tried to cheat and set up almost flat television in front of the flat screens of the company Sony. The almost flat screens were actually part of a ball with an enormous radius, so that a small part of it (used as the screen) seemed almost flat.
Back 10 years - LCD Just around the corner
A year after the establishment of the site, somewhere in 2002, has risen The first criticism Screen CRT. Screen, sample SyncMaster 1200NF Was 20 in size, weighing 31 and a half kilogram, and cost NIS 5000. The technology did not march in place and another breakthrough in the field was already just around the corner. Around the same time, the early 2000s,LCD Has begun to penetrate the computer screens market, this after Which was first marketed for domestic use At the end of the 90.
|Everyone had one|
ScreensLCD The newcomers were thinner, consumed less power and emitted less radiation and heat, but had unusually long refreshments that blurred rapidly changing images (such as movies and computer games). During this period, screens LCD Were mostly incorporated in laptops, but they had little use in the house. In 2007 the wheel turned and the X-LCD Bypass SalesCRT: They became cheaper, introduced Higher refresh rates And set up a real competition in front of the screensCRT. The sleek and elegant design of theLCD Have made them the most popular screens ever since.
The same year was also published Review the second screens of the site, Which was detailed and included a number of screens LCD Sized 24, which were then considered large and very spacious screens for the PC, the most expensive of which was sold at the time 8,600 shekels. A few months later she also immigrated Review of 19 inch screens "are worthwhile" More, when their prices fluctuated around NIS 1,500. ScreensLCD Have become the preferred choice of the average consumer, but we were not overly enthusiastic about them at the time. The viewing angles were poor, the quality of the picture was poor, the refresh times and other disadvantages made the cheap screens into an obviously unprofitable deal.
|And they all wanted to|
With theLCD Accessible to the general population, we made sure to release on the site a comprehensive guide to the subject of screens in two parts: Part a' And Part B, Which explains how screens work and what data to check before purchasing such a screen. To our surprise, this guide is relevant even today, does this symbolize technological stagnation?
Breaking the Boundaries - 28 Inch PC
In 2008 inch 28 screens have entered the picture. Although That the screen we have examined Was not particularly brilliant, the 22-inch screens Which were examined You've already seen other results. They were cheaper and more quality than the screens of the past year, and became an attractive purchase.

Size 28 and FHD resolution
Since then, they have penetrated the market Screens LED Which increase their market share quickly at the expense of theLCD And screens 3D Still shuffling behind. Between 2010 and 2011,LED Push theLCD Beside. The screen contrasts shot up, they showed Performence Better in daylight and viewing angles have become much wider. The attractive prices also contributed to the move.
Meanwhile they wander around
In the meantime, new technologies are based on the foundations of theLCD And do not cause a real revolution. ScreensLED And the modern 3D has indeed become the The screens are thinner, The picture is sharper and the colors are more accurate, but this is not a revolution. Among the pioneers, Sony is working on Development screen-Glasses Which provides the user with a more intimate and rich viewing experience. It will be interesting to see the next revolutionary development in personal computer display.
