The differences between in-cell,on-cell and out-cell iPhone displays.

Here is a brief summary of the differences between in-cell, on-cell, and out-cell displays on iPhone screens:

• In-cell displays: These displays integrate the touch sensors into the display itself. This results in a thinner display and more accurate touch response. In-cell displays were used in iPhone models such as the iPhone 5, iPhone 5s, iPhone SE (1st generation), iPhone 6, and iPhone 6s.
• On-cell displays: These displays also integrate the touch sensors into the display, but they are layered on top of the LCD panel rather than integrated into it. This makes on-cell displays slightly thicker than in-cell displays but still thinner than traditional LCD displays. On-cell displays were used in iPhone models such as the iPhone 7, iPhone 8, and iPhone SE (2nd generation).
• Out-cell displays: These displays use a separate layer for touch sensors on top of the OLED panel. This results in a thinner display with better color accuracy and contrast. Out-cell displays were used in iPhone models such as the iPhone X, iPhone XS, iPhone 11 Pro, and iPhone 12 Pro.

In terms of performance, in-cell displays are generally considered to provide the most accurate touch response and the best visibility in bright sunlight. On-cell displays are generally considered to have a slightly faster touch response than in-cell displays and may be more power-efficient. Out-cell displays are generally considered to have the best color accuracy and contrast, as well as a thinner and lighter display.

Overall, in-cell displays are known for their thinness and accurate touch response, on-cell displays provide a balance between thinness and touch response, and out-cell displays offer the best color accuracy and contrast. However, the differences between these displays may not be easily noticeable in everyday use, and Apple does not typically disclose which type of display is used in each iPhone model.
