State the technology used in LCD
Some passive matrix (Pixels are illuminated in scanline order like a raster display but the lack of phospherescence causes flicker) LCDs have dual scanning, meaning that they scan the grid twice with current in the same time that it took for one scan in the original technology. However, active matrix is still a superior technology. As stated before, display devices using CRT and LCD technology need to refresh the screen before the picture disappears.
Progressive Scan: Progressive or non-interlaced scanning is a process which displays, transmits or stores moving images wherein, the lines of all frame are drawn in order. It is i
