• Screen Resolution
Screen Resolution is the number of individual pixels displayed along the horizontal and vertical axes of an electronic visual display device. It is typically represented in the format width × height. For example, a resolution of 1920 × 1080 means the screen displays 1920 pixels across and 1080 pixels vertically, totaling 2,073,600 pixels on the screen. Higher resolutions generally result in sharper and more detailed images.
The higher the display resolution is, the sharper and clearer displayed content can be because a higher resolution device will be made up of more pixels than a lower resolution device. Furthermore, more viewable content can fit onto a higher resolution screen.
• Aspect Ratio
Aspect Ratio refers to the proportional relationship between the width and height of a display screen. It is typically expressed as two numbers separated by a colon, such as 16:9 or 4:3. This means that for every unit of height, the screen has a certain number of width units. For example, a 16:9 aspect ratio means the width is 16 units for every 9 units of height.
Aspect Ratio plays an important role in how content appears on screen. A wider aspect ratio like 16:9 is commonly used in modern televisions and computer monitors, providing a more cinematic and immersive viewing experience. In contrast, more square-like formats such as 4:3 are often found in older display devices or traditional photography equipment.
• Pixels
Pixel (picture element) is a smallest controllable element of a display device and therefore pixels are basic building blocks of any image you see on screen. Each pixel is divided into three subpixels, each showing one color of varying intensity/brightness: red, green and blue (RGB).
By combining different intensities of the three primary colors (RGB) a single screen pixel can reproduce a wide range of colors within the color gamut. Modern smartphones and tablets may use varying numbers of subpixels per pixel, such as in PenTile matrices, but the underlying principle remains the same.
• Pixel Density
Pixel density is an attribute of a display device measured as number of device pixels within one inch of screen space, either in horizontal or vertical direction. Value of pixel density is expressed as DPI (dots per inch) or PPI (pixels per inch).
Pixel density determines how high is the definition of the display. The higher the pixel density of the display, the sharper and crisper are text and images being displayed.
Pixel density is equal to display's native resolution divided by screen size in inches and can be expressed as either of two following formulas:
- - PPI = total number of pixels horizontally / size of screen in inches horizontally
- - PPI = total number of pixels vertically / size of screen in inches vertically
Tablets, smartphones and even some modern laptops and computer monitors have pixel densities ranging from 200 ppi all the way up to over 500 ppi, upper part of the range occupied by smartphones.
