Progressive scanning has been used universally on computer screens since the beginning of the 21st century.
Progressive scan differs from interlaced scan in that the image is displayed on the screen by scanning each line (or row of pixels) in sequential order from top to bottom.
By progressively scanning the image onto the screen in a scan (rather than creating the image by combining the two halves), a smoother, more detailed image can be displayed that is better suited for displaying text and motion. Progressive scan is also less sensitive to jitter.
The images on which it is applied are classified as 1080p, 720p, 480p... according to their quality. It is used for high resolution images containing more data.
The quality values of ps images that increase in numerical value also increase. The poor quality, frame-by-frame images you encounter during digital focusing can be achieved in this way to a much higher quality than ordinary images. In order to get real efficiency, it is essential to use devices with high resolution during recording and broadcasting. This type of images, which can also be converted into h264, can be called HD.
ALiS plasma panels and the old CRTs can display interlaced video directly, but modern computer video displays and TV sets are mostly based on LCD technology, which mostly use progressive scanning. Displaying interlaced video on a progressive scan display requires a process called deinterlacing. This is an imperfect technique, and generally lowers resolution and causes various artifacts—particularly in areas with objects in motion.
