Cathode ray tube monitors

In addition to power-line coupled noise, computers and cathode-ray-tube monitors can be a troublesome source of interference in many clinical and laboratory situations. Digital logic electronics often involve fast switching of large currents, particularly in the use of switching-type solid-state power supplies. These produce and can radiate harmonics that spread over a wide frequency spectrum. Proximity of the amplifier or the monitored subject to these devices can sometimes result in pulselike biopotential interference. 

Computerized operator communication stations replace much of the conventional panel instrumentation in the control room. A number of human-machine communicahon stations, each essentially comprising a keyboard and color cathode ray tube monitor, are located on the main control room panels. The displays provided on the monitors include... 

Monitors. Cathode ray tube (CRT) monitors ate a key element of electronic prepress systems, providing an electronic canvas for the operator. They may also be used to judge general adequacy of color in a process called soft proofing. 

Uses. The main appHcation for strontium is in the form of strontium compounds. The carbonate, used in cathode ray tubes (CRTs) for color televisions and color computer monitors, is used both in the manufacturing of the glass envelope of the CRT and in the phosphors which give the color. 

Most monitors are display terminals that use cathode-ray tube (CRT) displays, which function by exciting a layer of phosphors with an electron gun. These devices include monitors used with PCs and terminals used with mainframes or minicomputers. Features such as color, resolution, and size influence power requirements. Most PC monitors are... 

Another name for a beam of electrons is a cathode ray. Cathode ray tubes, or CRT for short, are used extensively in video monitors and televisions. The electrons are ejected from the electron gun and directed at a screen coated with substances that glow different colors when struck with the electrons. The electron beam must strike different regions of the screen at different times and frequencies to create a clear...

Cathode ray tubes (CRTs) are almost universally used in colour televisions and still dominate in the display monitors of desktop computers. They are obviously not suitable for laptop PCs, because of bulk and weight, where currently liquid crystal displays are the systems of choice. Neither are they the most suitable technology for very large area displays, where other display techniques such as plasma panels and electroluminescent devices offer advantages.

Phosphors for cathode-ray tubes, television screens, monitor screens, radar screens, and oscilloscopes are tested under electron excitation. Electron energy and density should be similar to the conditions of the tube in which the screen will be used. The phosphors are sedimented or brushed onto light-permeable screens and coated with an evaporated aluminum coating to dissipate charge. The luminescence brightness and color of the emitted light are measured with optical instruments such as photomultipliers or spectrophotometers. 

Under regular light, it is difficult to see the waves traveling back and forth. For a better view, pluck the rubber band in front of a computer monitor or a television screen that uses a cathode ray tube. The light from these devices, which acts like a strobe light, makes the waves appear to slow down Vary the tension in the rubber band to see different effects. 

Field operating personnel have access to the computer through a man-machine input/output (I/O) system located in the Field office. The I/O equipment consists of a cathode ray tube (CRT) with attached keyboard, a card reader and a printer for permanent copy of transmitted information. The I/O system supplies all alarms and operating data needed to monitor production operations. 

The color tube of the television that we use at our home is simply a vacuum tube, or cathode ray tube (CRT). CRT s are frequently used in televisions, computer monitors or anywhere where it is necessary to produce a picture. 

When the commercial OMA (Model 1205, Princeton Applied Research Corporation, Princeton, NJ) became available, we recognized its potential as a replacement for the photomultiplier detector. The vidicon detector surface was divided into 500 channels, the image could be seen on a cathode ray tube (CRT) monitor in real time, the intensity profile was available in digital form, the profile could be time-averaged for any desired number of video scans, and the final profile was stored in internal memory for transfer to an external output device. Not only had a considerable amount of work gone into its development and the verification of performance, but its potential for use for a variety of physical techniques would ensure the construction of enough units to support further development of the system. Moreover the need for low-light-level detectors for other purposes would lead to further improvements in detector devices. 

From the 1850s on, physicists had studied electric currents in tubes from which almost all the air had been evacuated. Electricity could pass from the electrode (cathode) at one end of the tube to the electrode (anode) at the other. A glow appeared on the walls of such a tube when electricity passed through it. The glow was attributed to rays from the cathode, or cathode rays. (The phenomenon is familiar to anyone who has ever watched television or used a computer monitor the screen that we view is part of a cathode ray tube.) William Crookes discovered in 1879 that electricity itself produced the light and that the cathode rays were in fact streams of electrically charged particles.
