What is a Pixel?

When we hear the term “Pixels”, we immediately think of a square of small gray dots that can be made by the most advanced computer monitor. The manufacturers of these monitors have decided to call it a pixel, but this is actually incorrect.

Light and Energy

What we consider pixels to be are pixels of light or energy that is provided by the amount of time in between the incident light and the output light. The number of photons that make up a second of LCD display will give us the “pixels” of each second. This is the reason why it is commonly referred to as a “pulse”.

For instance, red and blue pixels are all made of photons that are different wavelengths of the same color. These are called red, blue, green, and infrared (IR) colors respectively.

These individual colors are made of different frequencies of light. There are a set of photons that provide the exact same color for each pixel, which is necessary for the display of any image to be successful. Therefore, it is most commonly referred to as RGB.

To get an idea of what pixels are to you, it is easiest to look at a digital TV that has a dot-matrix liquid crystal displays. This means that each pixel is just a single color with three horizontal lines. The third line indicates the length of the color, which could range from black, white, or grayscale.

These colors are only meant to be colors, because the wave forms are created as optical devices that are not real colors. However, when you see the images on your television screen, you will realize that the images are not truly colors, but instead a series of dots with a very short wavelength.

For most of us, this is not a problem, but the human eye does not work with this. For example, if you looked at a person, you would see a series of dots which are partially solid colored. If you paid close attention, you could notice that the dots in the middle of the picture did not make up the whole picture, but were there as a background.

This is what the human eye perceives as a “solid” dot, and this is called a monochrome image. In this case, the human eye is trying to figure out what colors were used, and not a complete image. A pixel is not an image that the human eye can fully perceive, but it still plays a significant role in our perception of the image.
