This article is a follow up to "Understanding Screen Size, Resolution, and Pixel". It attempts to provide more clarity and in-depth knowledge of the different screen resolutions of smartphones in the market. Not just of the TECNO brand, but in general.
♦ HD: HD stands for High Definition. A device with an HD display has a resolution of 720p (progressive scan) with a corresponding picture element (Pixel) of 1280 x 720. These numbers represent the basic building blocks of a digital image or display. Digital images/displays are made up of small squares, just like a tile mosaic on a wall. Though a digital photograph looks smooth and continuous, just like a regular photograph, it is actually composed of millions of tiny squares. This tiny squares refer to Pixels.
The resolution of an image or display tells you of the total number (width by height/horizontal by vertical) of pixels present. So, a 1280 x 720 display contains 921600 pixels (1280 multiplied by 720).
♦ FHD:: This stands for Full High Definition. A device with an FHD display has a resolution of 1080p (progressive scan) with a corresponding picture element (Pixel) of 1920 x 1080. This means an FHD display contains 2073600 pixels (1920 multiplied by 1080).
♦ QHD:This stands for Quad High Definition. A QHD device has a resolution of 1440p (progressive scan) with a corresponding picture element (Pixel)of 2560 x 1440. This means a QHD display contains 3686400 pixels (2560 multiplied by 1440).
The Q in QHD which stands for Quad (4) comes from dividing 3686400 by 921600 which is equal 4. So QHD is 4 times the amount of pixels contained in an HD display.
♦ qHD: Notice the difference between this (qHD) and the previous (QHD). You may say both are the same for having same letters but they are not. QHD is different from qHD. The later (qHD) is of 540p (progressive scan) with a low resolution of 960 x 540. This means a device with a qHD contains 518400 pixels (960 multiplied by 540).
♦ 4K: Just as QHD is 4 times the pixels in an HD display, 4K is 4 times the pixels in an FHD display. A device with a 4K display has a resolution of 2160p (progressive scan) with a corresponding picture element (Pixels) of 3840 x 2160. This means a 4K display contains 8294400 pixels (3840 multiplied by 2160).
If you divide the amount of pixels (8294400) contained in a 4K display by that contained in an FHD display (2073600), you get the number 4.
8294400 ÷ 2073600 = 4, hence 4K.
The Camon 16 Premier doesn’t have this resolution, but it can shoot videos in 4K. What this means is that it can shoot videos at 4K resolution.
Though there are other resolutions of smartphones out there, these are the ones I feel are most relevant to this article.
See comparison photo below for different resolutions.
Here’s something I’m sure you’ve missed or didn’t think of after reading to this point.
TECNO devices sort of disagrees with these resolutions I made mentioned of despite falling within its categories. Take, for example, the CAMON 15, which has a resolution of 1600 x 720. This numerical figure is close to that of an HD display (1280 x 720). So what’s the explanation for this?
The CAMON 15 has more pixels (1600) in the horizontal region than the normal HD (1280), with the same amount of pixels (720) on the vertical region with that of the normal HD (720).
