HD applications
HD is the Chinese abbreviation of "High Definition" in English, which means "high resolution[1]". It has four meanings: high-definition TV, high-definition equipment, high-definition format, and high-definition movies. Because HD means high resolution, tablet applications usually have HD logos. HD refers to the vertical resolution of the picture being 1080i, 720p or 1080p. 1080i means that the resolution is 1920*1080, using interleaved scanning, presenting 30 complete pictures per second; 720p means that the resolution is 1280*720, using sequential scanning, showing 60 complete pictures per second; 1080p means that the resolution is up to 1920*1080, using progressive scanning, presenting 60 complete pictures per second.
