1 pixel puzzle4/2/2023 The next standard in known as 4K (or Ultra-HD), a display resolution of around 4000 x 2000 pixels. This means that each pixels on the 40” screen is larger than each pixel on the iPhone and as such the images are not seen as sharply or as detailed as on the iPhone screen.Īs technology does, new and improved display resolutions are rapidly becoming adopted. – A 40” LCD TV screen has a resolution of 1920 x 1080 pixels in a physical screen size of 93cm x 52cm – An iPhone 7 Plus has a screen resolution of 1920 x 1080 pixels in a physical screen size of 12.2cm x 6.8cm (landscape) A good example is the comparison of an iPhone to an LCD TV screen: It is not a measurement of physical size. This standard in commonly known as Full-HD and is a 16:9 aspect ratio.ĭisplay resolution is the width and height dimensions of a display device in pixels. The most widely accepted screen resolution for modern display devices is 1920 x 1080 pixels. Prior to the 16:9 standardisation the old televisions sets had an aspect ratio of 4:3, a much squarer display. The ratio simply means that for every 16 pixels horizontally there will be 9 vertically. Since around 2009, the most common aspect ratio for display devices is 16:9, as close a ‘standard’ as is likely to exist, your computer monitor and your home LCD TV are examples. In very simple terms a ratio is the relationship between two quantities, for example: 1 cup of rice to 2 cups of water = a 1:2 ratio. It is important to note that an ‘aspect ratio’ is a separate measurement to screen resolution, although they are inherently linked. When the three colours are combined as reflected light they are visible as black. Black is the absence of any colour.ĬMYK (Cyan, Magenta, Yellow and Black) is a subtractive colour model used for all printing. When the three colours are combined as emitted light they are visible as white. RGB (Red, Green and Blue) is an additive colour model used for all digital displays. It is worth briefly touching on colour models to understand how they relate to digital displays and printing. In digital displays each pixel is made up of three colour filters red, green and blue (additive colour). To complicate things even further a pixel can also be used unit of measurement, this is more common in web development and we won’t go into detail this time. It is not a fixed unit of measurement, like a centimetre or a metre, and is somewhat dependent on context such as in print, digital cameras or digital displays as to its manifestation as an output. ![]() ![]() In general, a pixel can be defined as the smallest single component of a digital image. While this is an extremely technical and complicated field I have attempted to provide an overview of some common terms and standards without being overly technical. At an events level we are producing bigger and better digital content and pushing the boundaries of available technologies. Vision systems and video standards are complex.Īt a consumer level we are bombarded with technical specifications in an attempt to sell the latest and greatest.
