Part 7/10:
Why Screens Are Not Mixing Colors Haphazardly
The host emphasizes that monitors and digital displays are not projecting "white" by heat or intensity alone. They use the RGB color model, adjusting the brightness of each channel to produce a full spectrum of colors, including white. When all three are at maximum intensity, the outcome is perceived as white light.
He demonstrates this using a programmable RGB LED panel, showing how varying the brightness of each channel results in different colors. When all channels are at a low setting, the light is faint, and the display appears dark or gray, depending on the combination. Importantly, the display doesn't emit gray or white light directly but mixes the RGB signals at different intensities.
