![]() ![]() Most of the companies that make displays always test each screen after manufacturing to make sure all its pixels work well. While manufacturing a display, errors can occur that could result in having one or more transistors of your display not working. There are several causes of dead pixels, and some of these include the following: Manufacturing defect Also note that a pixel can be stuck to any of the color combinations of the 3 primary colors. When no color is being displayed by the pixel, its default color will be black. So, when the transistor is off, the pixel will neither have the power nor the signal of the colors to display. Each of the pixels in any display is controlled by one transistor to give it signals of what colors to display and the intensity. For those who may not know, a transistor refers to a small semiconductor device that is used to amplify or switch electrical power and electronic signals in electronic devices. Technically a pixel stops working when the transistor that powers it up fails. So, in a situation where your display has very tiny pixels that can't be seen by the naked eye, you may not be able to see a dead pixel if there's only one. ![]() The more dead or stuck pixels you have, the larger the spot. The size of this dot depends on the number of pixels that are dead at that particular point. Noticing a dark, white or color-stuck spot on the screen, you probably have one or more dead pixels.

That is why the same video will appear different on an HD (1280 x 720 pixels) display and a Full HD (1920 x 1080 pixels) display. The number of pixels per inch that a display has will largely determine the quality of images and videos it will show. The fact that the changes happen so fast is the reason it is hard to see with our naked eyes how each pixel changes color. In the case of videos, the change of colors for each pixel change in rapid succession at a speed that depends on the frames per second for the video being played on the display. That's how each pixel produces the desired color that when combined create the images that we see on the screen. In another scenario, turning on the red and green subpixels will produce yellow, turning on all the three subpixels produces white, and turning on-off all of them shows black. So, if you want to display an entirely red image, only the red sub-pixels shall emit light, which will then make the entire display to be red. ![]() Based on what you want to display, the amount of color that is produced by each dot may vary. Each of these dots is responsible for displaying one of the three primary colors, that are blue, green, and red. In any display, each pixel comprises three dots that can be called sub-pixels. Most of them have over 300 pixels per inch, which makes it almost impossible to see the individual Pixels with your naked eyes. This is most likely the case with most of the newer smartphones that have come through in recent years. 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.

If you closely look at one of your TVs at home while it is turned on, you will see very small squares on the screen. ![]()
