Why do the colours on a phone screen look the same from all directions but a laptop’s gets distorted when you look at it from a different angle?
In: Technology
Most phones these days are using OLED screens. Each pixel’s red, green and blue dots glow on their own.
As opposed to most (but not all) computer screens which operate on a backlight which is white, and then colour filters in order to produce the red, green, and blue as well as control the brightness of each.
These filtering layers do have an impact on the viewing angle. Not being straight on means the filtering mechanisms start becoming more of what you see… Like, on a house a window has a frame that goes on both the inside and outside of the home. Viewed straight on, you don’t really notice the frame and can see in/out of the house fairly well. But at an angle, you see more of the frame itself and its thickness through the walls meaning less space is available to see into the house…
Whereas an OLED doesn’t have a window with a frame, and instead just attaches a lamp to the outside wall of the house.
OLED has a life span and will die out over time, so for screens that are not powered up as much, they make more sense.
