The most common types of screens used in mobile phones are LCD (liquid crystal display) and OLED (organic light-emitting diode).

LCD screens are made up of a backlight, a layer of liquid crystals, and a layer of colored filters. The backlight shines through the liquid crystals, which twist and untwist to control the amount of light that passes through the colored filters. LCD screens are known for their bright, vibrant colors and high resolution.

OLED screens, on the other hand, use organic compounds that emit light when an electric current is applied. This means that each individual pixel can turn on or off independently, allowing for deeper blacks and more vivid colors. OLED screens are also known for their energy efficiency, as they don’t require a backlight.

Both LCD and OLED screens have their own advantages and disadvantages, and which one is better depends on personal preference and use case. Some people prefer the vibrant colors and high resolution of LCD screens, while others prefer the deep blacks and energy efficiency of OLED screens. by ifixparts.com
