Color CRT displays, the technology underlying many television and computer monitors before the early 2010s, require degaussing. Many CRT displays use a shadow mask (a perforated metal screen) near the front of the tube to ensure that each electron beam hits the corresponding phosphors of the correct color. If this plate becomes magnetized (e.g ...
Upon power-up of the CRT display, the degaussing circuit produces a brief, alternating current through the coil which fades to zero over a few seconds, producing a decaying alternating magnetic field from the coil. This degaussing field is strong enough to remove shadow mask magnetization in most cases, maintaining color purity.
Commands for adjusting CRT display geometry, such as parallelogram, pincushion, etc. Image adjustment Various general commands such as display orientation, degauss, gamma, zoom, focus, brightness/contrast, backlight control, etc. [a] It is possible to select the input source using a VCP command.
An aperture grille is one of two major technologies used to manufacture color cathode-ray tube (CRT) televisions and computer displays; the other is the shadow mask. The first patented aperture grille televisions were manufactured under the Trinitron brand name.
Degassing, also known as degasification, is the removal of dissolved gases from liquids, especially water or aqueous solutions.There are numerous methods for removing gases from liquids.
Getting a raise is a huge accomplishment, so congratulations! Once the additional money starts rolling in, you’ll want to make sure to use it in the best possible way.
Cromaclear is a trademark for CRT technology used by NEC during the mid to late-90s. This adopted the slotted shadow mask and in-line electron gun pioneered by the 1966 GE Porta-Color and used by most then-current television tubes to computer monitor use.
An external degausser is often used by governments to protect sensitive information from being burned into the display of monitors and televisions.
