The history of the pixel.


Pixel means picture element, but it has been used only recently once the digital era has begun. Previously you would have the lines in the mechanical television and in the electronic television. NTSC system had more than 500 lines, but digital era speaks in pixels, a square from the grid that builds the images.

A short history is appropriate here and the video from above presents such a short history. Nowadays pixels use the combining of three color, red, green and blue to generate the color we need. James Clerk Maxwell has established this process in the 1860s. Clever guy.
