Within a cathode-ray tube (CRT), the horizontal scan rate is how many times in a second that the electron beam moves from the left side of the display to the right and back. The number of horizontal lines displayed per second can be roughly derived from this number multiplied by the vertical scan rate.
The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image.
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, ... The value of the s-capacitors must be chosen based on the scan rate of the CRT, so ...
Scan rate is a term used when discussing raster-scan video, describing the speed at which the image is transmitted or displayed. There are two types: There are two types: Horizontal scan rate , the number of times per second that a single horizontal line of image data is transmitted or displayed
The following table compares cathode-ray tube (CRT), liquid-crystal display (LCD), plasma and organic light-emitting diode (OLED) display device technologies. These are the most often used technologies for television and computer displays.
There is a misconception that once a scan line is complete, a cathode-ray tube (CRT) display in effect suddenly jumps internally, by analogy with a typewriter or printer's paper advance or line feed, before creating the next scan line. As discussed above, this does not exactly happen: the vertical sweep continues at a steady rate over a scan ...
Cathode-ray tube (CRT) displays typically operated at a vertical scan rate of 60 Hz, the same as SDTV content they displayed, which resulted in noticeable flicker. The same was true of other impulsed technologies such as plasma displays .
A scan line (also scanline) is one line, or row, in a raster scanning pattern, such as a line of video on a cathode-ray tube (CRT) display of a television set or computer monitor. [ 1 ]
