A pixel is a unit of measurement for the screen of any modern monitor, be it a computer, laptop, mobile phone, navigator, and so on. In other words, answering the question of what a pixel is, you can answer that this is just a point. That is, if they say that the picture size is 100 * 30 pixels, it means that this picture consists of 100 * 30 pixels. Thus, the pixel size is one point on the monitor of your computer or other device. Pixels can be black and white or color. Thanks to them, controlling the brightness of the glow, you can draw, draw, build various graphics, edit the image, view your favorite movies.
Pixels are used to evaluate monitor resolution. The more pixels the monitor of your device can reflect, the sharper and better the image will look. In web design, they are used to indicate the size of an image, photograph, any particular object, table cell. To do this, apply such parameters as the height and width of the image.
Now you have the most general idea of what a pixel is. But now we will try to analyze this concept in more detail.
Pixel Information Elements
Each pixel includes five pieces of information. Two of them are responsible for the coordinates of the pixel, that is, its location vertically and horizontally. The remaining three are responsible for color. They determine the brightness of red, blue and green. These five elements together make it possible for the reader to place a point in the desired location on the screen and determine its correct color. Together, the pixels on the screen form a frame.
A megapixel is one million dots that create a solid image. Typically, megapixels are used to measure the size of a photograph, image, video.
What is a broken and stuck pixel?
Surely, you have heard the concept of a “broken” pixel. We’ll try to figure out what this means. First, let's figure out what are liquid crystal monitors. The matrix of such a monitor has a huge number of crystals, each of which is controlled by a thin-film transistor. In the event that the thin-film transistor ceases to function correctly, that is, fails, the image will not be displayed on this section. That is how “broken" pixels appear on the phone, monitor, camera, laptop or computer. This type of pixel is the most difficult to repair and dangerous for technology.
It should be said that a non-working pixel is not always black, since a pixel is a set of 3 sub-pixels - blue, green and red. Color change is achieved by turning the crystal. If this crystal is stuck, then when changing the image, it will display only the color on which it is "stuck". Often "stuck" pixels simply do not notice. You can fix this problem with a special program and a certain impact, even at home.
There are also other types of pixels, for example, “dependent” and “hot”. In fact, these are variations of the broken pixel, which will appear under certain conditions. In films, games, and working with images, such moments are likely to remain elusive to the eye.
Now you know what a pixel is and how it functions. And remember that in the event of a breakdown, that is, a “broken” or “stuck” pixel, it is best to immediately contact a specialized repair company to extend your life if possible. After all, no one will like to look at black dots instead of beautiful photos.
