| [* icon_note] Ever wonder what a polarizing film does? Join us for ***Science with iFixit*** as we shine some light on the inner workings of an LCD and why they need a polarizing film: | |
| [* black] First, the backlight shoots light through a thin layer of liquid crystals. As the light passes through it's reflected at different angles by the crystals' orientation. | |
| [* black] The angle of reflection determines the color of the light we see. In order to change the angle (and by extension, color) the display hardware must apply a voltage across the liquid crystals to change their orientation. | |
| + | [* black] In order to produce a wide range of colors, each pixel is broken down into three subpixels: red, green, and blue. |
| + | [* black] Separate voltages are used to adjust the intensity of each subpixel which, when combined, can create millions of different colors. |
