The Origins Of Our Lcd Screens And High Definiton Plasma TV In Vintage Computer Monitors
It may be amazing to current computer users who are used to small compact LCD monitors. Not only were initial computer monitors large and cumbersome but that the early monitors used by computer enthusiasts were Cathode Ray Monitors that were not color,
Initial vintage monitors were monochrome - one color only not the brilliant color displays that we take for granted today.
Some of these monochrome monitors were green or orange iridescent. Others were similar to a black and white television that is grey scale.
It is taken for granted now by young computer surfers and gamers that television was always "color", not so.
Initially TV broadcasts were in "black and white ".
Color TV had been developed but the technology but the widespread use did not arise till the early 1970's and even later in some areas.
The broadcasts were seen as black and white on those sets and color on color sets.
Color TVs could receive programs that were in the black and white mode as well. Sort of the backwards compatibility of the day.
What then would be the difference between the picture qualities of a television set a monitor has vastly greater resolution than standard TV sets.
The TV sets of that time (as opposed to current high end LCD and plasma high definition TVs) were basically 1950's technology - even the newer color TV sets. .
A monitor's screen display should be stable and of good quality, since the computer user may sit very close to the monitor and spend many hours reading the display.
If the images are fuzzy (low resolution) or waver constantly, you would have a throbbing headache and wavering eyes in no time.
Monitors have knobs to adjust for clarity. On vintage monochrome monitors these usually include a brightness knob which adjusts the illumination of the entire screen, and a contrast knob which makes the letters lighter or darker in relation to the background screen newer color monitors will have additional adjustments for color.
The question will arise - how did the vintage CRT (Cathode Ray Tube) monitors initially handle the color technology which came later and became the accepted standard.
A typical color monitor screen worked in much the same way as a standard CRT television.
The inside of the picture tube is coated with three different phosphors: red, green and blue.
Phosphors are special chemical compounds that glow with characteristic colors when bombarded a stream of electrons.
The phosphor gets "excited" and thanks to the additive properties of the color wheel the different colored lights resulting get mixed and that all types of combinations of the three primary colors result.
The end result is that virtually any color of the rainbow can be produced.
And as for the color white the eyes play a useful trick. When all three colors are mixed together in equal quantities, the eye sees this as "white light".
Finally the sharpness of the CRT color monitor or a TV set's image is determined by three factors: the monitor's bandwidth, its dot pitch, and the accuracy of its convergence.
Although the bandwidth and dot pitch are important to determine a good monitor, convergence is the real measurement.
Indeed we have come a long way from the initial simple vintage monochrome monitors. What we now take for granted with LCD monitors and indeed our high definition TV sets all originated with simple CRT monochrome monitor technology which was merged with the technology and tricks gleaned from the color TV industry.
We should all be grateful. We owe much to "Uncle Miltie".

Vintage Treasure Hunting In London
There are very few places in the UK better for hunting out vintage treasures than the world famous Portobello Road, West London. Fifteen minutes walk north from Notting Hill Gate underground station, or five minutes east from Ladbroke Grove station, under a giant tent beside the M40 flyover, Portobello Green Market flourishes on a Friday, Saturday and Sunday.
On Friday and Saturday at least thirty good dealers can be found selling a fantastic range of vintage clothing and vintage accessories. It's definitely not to be missed. Many of these dealers come to London each weekend from the provinces with new vintage and antique treasures gleaned from charity shops, auctions, house clearances and rag yards to sell on at very reasonable prices.
Serious vintage buyers are there early - 7am - and, in winter, take a torch. You will have plenty of competition, even at seven, because anybody who buys and sells vintage in London will be there. It is also popular with designers - established and student - Cath Kiddson is a regular, but most big-named designers, like Paul Smith - will usually send a representative buyer.
These designers are looking for vintage ideas for conversion. Vintage clothing was constructed quite differently when compared with today's fashion garments made in China or India, as cheaply as possible. It is interesting to see how vintage garments were cut and put together and sometimes, for just a few pounds spent in Portobello Road, a forgotten piece of dressmaking skill can be rediscovered. These details incorporated into the design of a new garment can often improve the shape and fall, possibly making the difference between success and failure of a whole line.
Designers also covet vintage prints and weaves, to be copied and converted. Cath Kiddson has made a huge success of incorporating vintage textile motifs into her designs for home-wares. A colourful printed design on a vintage skirt, dress, scarf, apron or even a lampshade that may have been popular in the nineteen-thirties is now out of copyright and free to convert. Textile print motifs that would have been very familiar to our grandmothers can now be seen copied and used, sometimes with slight alterations or additions, on book covers, plastic bags, tin boxes, rucksacks and (Kiddson again) even tents.
As the sun comes up, activity will be frenetic. Stallholders running back and forth between their vehicles and stalls carrying colourful armfuls of vintage clothing or pushing wheeled rails laden with vintage coats and dresses. Some arrive with anonymous black-plastic sacks bulging with vintage secrets, which are simply tipped onto the floor. Buyers rush from place to place rummaging and haggling over vintage handbags, vintage shoes and even scraps of cloth. Arguments are common, but quickly settled; after all, everyone is there for the same reason, to trade and arguments are bad for business.
There are always famous faces around Portobello Road so don't be surprised to see celebrities haggling along with everyone else. In fact, if you don't see at least one famous face, I'd say, you weren't looking. Actors and models not only buy vintage, they also sell it. More than one stallholder on Portobello Green is a "resting actor" and there are a few ex-models too.
I guarantee, that if you deal in vintage textiles, wear vintage clothing or vintage accessories, or are furnishing you home in vintage style, a visit to Portobello Green on a Friday or Saturday morning will always be interesting, often exciting, definitely fun and sometimes very rewarding.
Sunday on Portobello Road is a little different. There is no need to be there before dawn as less established, casual traders dominate a much smaller selection of stalls with more emphasis on crafts. For the vintage hunter Sunday is much more hit or miss.
But, on any day in Portobello Road and the surrounding area you will find plenty of friendly coffee shops and cafes where, after vintage treasure hunting, you can have breakfast, read the morning paper and people watch.
One particularly amusing sight, if you are eating breakfast in the popular Mick's Caf

How can I make a neon shirt look more vintage?
I have this shirt I got from Panama City that's mint green with neon, rainbow print displaying the city. I sort of bought it without thinking. Is there anyway I can distress it or make it look more vintage?
Vary simple, this is what they do to give "fade" to shirts, i assume its cotton, nylon or rayon.
first get something riveted or at least a wooden spoon, now get some sand, the more course the better, wash it in hot water with the sand really whipping it up and running it up and down the riveted object. do it for about 10 min. This will open up the cotton fibers. rinse in warm water so it still shrinks up a little bit. now the most important thing, sun dry it. make sure to rotate as needed, this is what gives the fade.
now you know how its done, shop freely shopper.
