ELI5: How come old Gameboys looked great in direct sunlight but modern screens are unusable in bright conditions?
gpt
Old gameboy did not use back lighting and they were designed for the light to be provided externally.

Modern screens use backlighting and are designed for the light to come internally.


As a result excessive external light will cause glare on newer devices.


Back lighting is when the light source for the screen is provided from behind the screen.
