It can convert a beam of light of undefined or mixed polarization into a beam with well-defined polarization, polarized light. Once you remove the layers of film in the original screen, we proceed to install the light and polarized film, as we can see in the pictures above, on the left the screen is white when no polarized is inserted (you wont see any image), the center image shows the polarizer in a 90 degree angle, becoming blue when the unit is off… and lastly on the right the normal position of the polarizer, which makes it look that nostalgic green we all know…Ī polarizer or polariser is an optical filter that passes light of a specific polarization and blocks waves of other polarizations. When you add a backlight to the gameboy you must remove some layers, one of them is a polarizer, so it’s mandatory to add another one.
Basically is a filter that allows just light in one direction. In order for the GameBoy screen to show pixels, it is necesary a polarized film. There is a lot of information about it online but still some pictures don´t show very well the effect so I wanted to try and show it here. This will be a quick post about the polarized film found in Backlight screens for the gameboy.
