Understanding iPhone Screen Structure
Layers of an iPhone LCD Screen
An iPhone display isn’t just a single piece of glass. It’s made up of several key components:
- Glass: The top protective layer.
- Touch Digitizer: Detects touch input.
- LCD Panel: Displays images.
- Подсветка: Illuminates the screen for visibility.
Position and Role of the Touch IC in the Display Assembly
The Touch IC typically sits on the phone’s motherboard, managing signals between the digitizer and the processor. Its strategic placement makes it vulnerable to physical stress or manufacturing flaws, especially in older iPhone models.
