Mobile-device testing functions to assure the quality of mobile devices, like mobile phones, PDAs, etc.It is conducted on both hardware and software, and from the view of different procedures, the testing comprises R&D testing, factory testing and certificate testing.
The increased resolution over D1 comes as a result of a longer horizontal scan. The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image.
The p stands for progressive scan, i.e. non-interlaced. The 1440 pixel vertical resolution is double the vertical resolution of 720p , and one-third (about 33.3%) more than 1080p . QHD ( Quad HD ) or WQHD ( Wide Quad HD ) is the designation for a commonly used display resolution of 2560 × 1440 pixels in a 16:9 aspect ratio .
