![]() In situations where the display has too many pixels per inch, you will likely not be able to see the individual Pixels – Apple calls this retina display. The combination of these small squares is what gives your TV the ability to display images and videos. If you closely look at your TV at home while it is turned on, you will see very small squares or dots on the screen. ![]() For example, a display with a resolution of 1920x1080 pixels has a total of 2,073,600 physical pixels. The more physical pixels there are, the higher the resolution and the sharper the image appears. Physical pixels, on the other hand, refer to the actual number of dots on a display that make up an image. This number may be different from the number of physical pixels on the display, as the image may be scaled to fit the screen. Rendered pixels are the number of pixels that an image is actually composed of when it is displayed on a screen. The pixels in the two images above are not physical pixels. Zoomed-in image Distinguishing rendered pixels from physical pixels As you can see, zooming in reveals the small dots that constitute your image. We have drawn a square on the palm tree leaves, and have maximized it to make the second image. The first is a landscape scene of palm trees in the desert. You may find below an example of a high-resolution image and a second low-resolution one. In a digital image, each pixel represents a single point in the image, and the combination of these pixels creates the overall picture. The more pixels there are, the higher the resolution, and the sharper and more detailed the image will be. ![]() Pixels are arranged in a grid to form a display, and the number of pixels in the grid determines the resolution of the display. ![]() When it comes to displays, a pixel is also the smallest element of a display that is normally in the form of squares. If you tried to zoom any of your photos on your phone or PC, you will likely start seeing small squares, which may vary in number based on the quality of the device that was used to take the image. In digital imaging, a pixel is the smallest addressable element of an image. ![]()
