The smartphone repair market is booming worldwide. With the iPhone 15 Pro Max gaining popularity, the demand for durable, high-quality replacement screens has surged.

1. Understanding JK FHD iPhone 15 Pro Max Display Technology

1.1 LTPS (Low-Temperature Polycrystalline Silicon) Technology

JK screens use LTPS display technology, which offers multiple advantages over traditional TFT-LCD and AMOLED displays:

• Higher pixel density for sharper, clearer images.

• Stable color reproduction for professional content creation and media consumption.

This ensures that videos, games, and everyday apps appear vibrant and accurate, even after extended use.

1.2 In-cell Touch Panel Structure

The in-cell touch panel integrates the touch sensor directly into the display layer, offering:

JK’s LED backlight structure guarantees:

• Uniform brightness across the 6.7-inch screen
