Primary Colors-In light (and in monitors, which produce light) they are the basic colors-red, green and blue-that can be added together to create any other color.
R
Raster Area-The area of the CRT which has the ability to display a video image.
Refresh-The process in which the monitor repaints an image.
Refresh Rate-The rate at which a monitor repaints an image. A refresh rate of 60 Hertz, for example, means the screen is drawn 60 times per second. A low vertical refresh rate produces visible flicker.
Resolution-A standard by which the sharpness of the monitor is defined. It is defined by the number of pixels that are used to form an image. For example, a resolution of 1024 by 768 has 1024 pixels running horizontally and 768 pixels running vertically for a total of 786,432 pixels.
Roping-Describes an image distortion that gives solid straight lines a helical or twisted appearance. This problem is caused by poor convergence.
S
Scan-The process by which an image is developed. The electron beams excite the phosphor on the monitor screen dot by dot and line by line. The faster the scanning the more stable the image.
Shadow Mask-A mask formed behind the screen of a monitor. It consists of small holes that are used to filter and focus the light emitted from the electron gun.
Sharpness-Rather subjective and dependent on the eyes’ interpretation of the image.
Slot Mask-Also called aperture grille. Serves the same function as the shadow mask except that the slot mask is made up of vertical wires stretched behind the screen. This mask technology enables more light to filter through the mask, therefore giving the screen a brighter image.
Stripe Pitch-The equivalent of dot pitch on Trinitron tubes; the distance between one stripe and the next one of the same color, expressed in millimeters.
SuperClear™-SuperClear offers up to 30% more brightness and contrast, due to the addition of micro filters, than conventional CRT’s.
SVGA-An acronym for Super Video Graphics Array. A standard characterized by a resolution of 800 by 600.
