list the operating characteristics of the following display technologies; raster refresh system , vector refresh system, plasma panal , cds
Answers
Answer:
1)Raster Refreshsystem:
In which the electronic beam makes the screen a number of lines,and draw each one and this is called (scan lines) and the pictureis refreshed every interval of time from the refresh buffer framebuffer. Raster display refresh system includes a charge coupleddevice (CCD) circulating refresh memory for maintaining a displayof information on a cathode ray tube (CRT)screen.
It'scharacteristics:
a)The pixels in the screenaren't related.
b)Fast in loadingimage.
c)whenmagnifying, the quality of the screen decreases.
2) Vector Refreshsystem:
Ituses a short persistence phosphor whose coating must be reactivatedby the electron beam. This reactivation called the refresh, takesplace at a rate of 30 to 50 times per second. The vector refreshsystem also requires a display file and display controller. Thedisplay file...
