The Cathode Ray Tube\nAlmost all TVs in use today rely on a device known as the cathode ray tube, or CRT, to display their images. LCDs and plasma displays are sometimes seen, but they are still rare when compared to CRTs. It is even possible to make a television screen out of thousands of ordinary 60-watt light bulbs! You may have seen something like this at an outdoor event like a football game. Let's start with the CRT, however, because CRTs are the most common way of displaying images today. \n\n \nInside a CRT\nAs you can see in the below drawing, there's not a whole lot to a basic cathode ray tube. \n\n \nTo see the rest of this go to: www.howstuffworks.com\n \n\n\n\nThere is a cathode and a pair (or more) of anodes. There is the phosphor-coated screen. There is a conductive coating inside the tube to soak up the electrons that pile up at the screen-end of the tube. However, in this diagram you can see no way to "steer" the beam -- the beam will always land in a tiny dot right in the center of the screen. \n\nThat's why, if you look inside any TV set, you will find that the tube is wrapped in coils of wires. On the next page, you'll get a good view of steering coils. \n\n\n \n\n\n\nThe terms anode and cathode are used in electronics as synonyms for positive and negative terminals. For example, you could refer to the positive terminal of a battery as the anode and the negative terminal as the cathode. \n\nIn a cathode ray tube, the "cathode" is a heated filament (not unlike the filament in a normal light bulb). The heated filament is in a vacuum created inside a glass "tube." The "ray" is a stream of electrons that naturally pour off a heated cathode into the vacuum. \n\nElectrons are negative. The anode is positive, so it attracts the electrons pouring off the cathode. In a TV's cathode ray tube, the stream of electrons is focused by a focusing anode into a tight beam and then accelerated by an accelerating anode. This tight, high-speed beam of electrons flies through the vacuum in the tube and hits the flat screen at the other end of the tube. This screen is coated with phosphor, which glows when struck by the beam.

The physics and basic theory of the CRT (picture tube) have not changed at all. The electronics and such have been dramatically improved - but the electrons smashing into the phosphor and emitting light is the same.\nHowever, the newer Plasma, LCD and DLP sets are completely different.

I bet it does work, but you don't know how to use it...\n\nWhen you press Print Screen, what your computer does is COPY the image on your screen.  That means, that after you press it, you have to go into a program like Microsoft Paint and PASTE it.  \n\nI hope that was the problem, good luck!

The tubes need an initial surge of electricity to overcome the higher resistance that exists before the current is flowing.  Usually this is done by charging a capacitor to a high voltage.  I believe the click is the initial electric discharge.

That could get extremely detailed, but here is a simplified explanation that can fit here.\nThe TV screen is a collection of little pixels, one besides the other, arranged in lines.  The camera that takes the picture that is to be shown on TV grabs the image and then evaluates the color in each pixel of each line, and each lines, and sends that information as a signal.  The TV receptor receiving that signal (that could have been encoded, sent by cable or through radio waves, etc) then gets a signal that essentially says "first line" followed by the description of each pixels.  Then it sends the third line (the even lines are sent after the odd ones, this is what is called interlacing) and the 5th and so on until the end of the half picture.  The electronics in the TV use the signal to project a beam of electron of variable intensity to a target that is made of fluorescent phosphor, that light up as a result, and you see the picture from the other side.  Evidently, if your TV is a LCD or a plasma unit, the technology to actually reproduce the image varies from the old cathodic tube method, but the result is the same, you get an image.

you proabaly need to select the "INPUT" source for the PiP and yeah, sometimes its difficult to change the channel on the smaller pic.  I think on my TV its easier because the big pic will be off satellite and the PiP 'source' coming from the VCR so I can just change the channel on the VCR using its remote (or the satellite remote if needed).

it's usually called tube lighting

The number of pictures (Files) does not affect software.\nYou may have other issue.\n\nWhat is exactly paint is doing? need more info\n\ne-mail me

I would be writing pages to tell you about this stuff so just go to http://www.hardwaresecrets.com/article/209 and read how a CPU works.\n\nI have the feeling you're just trying to see if someone would actually draw you a picture and...well no.

i'm not sure where, but if you just take a peice of paper and draw lines on it in wacky ways it will work, than all you have to do is past the paper to like the back of a picture that has been printed on some thick poster board or something

Small transparent photos that are put in a slide projector that display the image by a powerful light bulb which beams it's light through the slide so that the image is projected across on to a  very large white screen or wall in a darkened room much the same way as it does with a cinema projector with movies. The exception is that the images are static like photographs and displayed as moving images.\nA collection of slides (photos) are put in a carossel and you click a button and the projector will go to the next slide photo.\nThe advantage of a slide show is that you can show a lot of people a photograph as the image that is displayed on the screen can be several feet wide and show good resolution depending on the power of the projector is the size of image screened.\n\nAlso they are not negatives because negatives projected would only screen a negative image same way as if you looked at a negative. A projector cannot reverse the colors of a negative print to make it a positive print it only shines a beam of white light through it.\nSlides are therefore made of positive prints.\n\nNegatives are only used so if you wish to have more copies made of photographs you can take them to be developed to make more positive prints (normal photos)

It depends on what you class as a television. There were monitors around before the camera such as wave form and vectorscope monitors so that engineers could see visual images of electronic activity within an electronic system such as radio. They used these when researching how to capture moving images i.e. the TV camera, we still use them for monitoring the technical quality of the pictures we produce. But in terms of what the general public knows as a TV monitor it was developed concurrently with the camera. The picture was captured on a tube converted into signal sent down a cable and then reproduced on the tube in the TV.\nI've just had this debate with one of our technical directors our news director and some other staff and the majority say the monitor or TV in it's crudest form came before the camera.\nHope this helps.

Most of the information in this guide applies to all video cameras whether they are digital or analog. Analog is the term used for all older style video cameras, recorders and players. The main feature of analog representations is that they are continuous. Digital representations consist of values measured at discrete intervals. These intervals can be so short as to simulate continuous movement.\n~~~Logigly  video images comes from a tape or memory card~~~\n~~~if you wish to understand the difference between Analog and digital video you must first understand the diference between those who created them (CAMERS) the difference between a digital and a analog camera~~~\nForm more documentetion Just CLick the link below:

Thats the JAVA Script they have.\n\nIts related to mouse movement... based on which the image moves.

CRT is a "Cathode Ray Tube" CRT displays have been used up until recently for everything from TV sets to computer displays. Now with Plasma screens and LCDs and other forms of technology, the CRT is one of many forms of technology. But when people call TV "The Tube" it refers to a Cathode Ray Tube.

The screen is coated with phosphorous and the tube itself is evacuated to form a vacuum.\n\nAn electron beam is produced by a heating element in one end of the tube.\n\nMagnets can focus the electron beam or make the beam spin.\n\nThere are vertical and horizontal plate capacitors in the tube that deflect the electron beam up/down or sideways.\n\nElectrical signals from a TV or computer control the focusing magnet and the charges on the capacitor to produce a picture on your screen.\n\nThis is pretty much a simplistic description of how they work.

TVs use cathode ray tubes to provide the picture, they need time to "warm up" before you can see the picture.  The speakers that relay the sound though are basically instantaneous.
