To create a display, each pixel in the camera chip is being flashed three times. The process starts with a dark pixel which is white until it gets flashed and becomes red. Then the red one flashes up to yellow and then down to the green, then finally the green turns into blue before going black again.
The computer engineer named Bill Buzbee studied this issue from his own personal experience, where he noticed that outdoor displays looked far brighter than indoor displays of equal quality. This was because there were simply not enough light particles to illuminate an indoor display unless they were very close to a window or near a light source.
