Everything You Need to Know About Screen Assembly and Display Repair
In the age of mobile technology, a damaged phone display is one of the most common issues users face. Whether it's due to accidental drops, screen malfunctions, or pixel damage, understanding the available options for a screen replacement is essential. From LCD screens to hard OLED screens, knowing what’s inside your device helps you make better repair decisions.
This guide breaks down screen repair parts, compares OLED technologies, and explains key features like Face ID support and OEM iPhone screen.
Understanding Screen Assembly Components
A screen assembly is a combination of components that together form the front display of a smartphone. It typically includes:
LCD or OLED panel – for visual display
Touch digitizer – to detect touch input
Glass lens – for protection
Frame/housing – optional, depending on model
Replacing the entire screen assembly is common when both the display and touch response are damaged.
Which Is Better: LCD or OLED?
Both LCD screens and OLED screens are widely used in smartphones, but they differ in technology and visual performance.
Feature LCD Screen OLED Screen
Brightness High, but limited contrast Deep blacks and vibrant colors
Power Usage More battery consumption Energy-efficient for dark images
Thickness Thicker due to backlight Slimmer profile
Cost More affordable More expensive
Use Case:
Incell LCDs are best for budget or mid-range devices.
OLED screens are ideal for premium models like newer iPhones and flagship Androids.
Hard OLED Screen vs. Soft OLED Screen
There are two main types of OLED displays:
1. Rigid OLED screen
Made with glass substrate, these are:
More affordable
Easier to produce
Slightly thicker and less flexible
2. Soft OLED screen
Made with plastic substrate:
Flexible and thinner
More resistant to drops
Used in flagship phones like iPhone X and above
While both offer stunning visuals, the premium OLED panel is more durable and provides better display quality.
How to Replace a Smartphone Screen
When choosing a display replacement, consider the following options:
Original Equipment Manufacturer screen – Same quality as the factory-installed part
Aftermarket screen – More affordable, quality may vary
Incell screen – Combines LCD and digitizer for slim design
Pressure-sensitive display – Supports Apple’s pressure-sensitive features
Professional technicians recommend OEM parts or high-grade aftermarket options for best performance.
What is an LCD Touch Screen?
An touch-enabled LCD merges the display and touch sensors into one. It allows for:
Smooth touch experience
Slim profile
Affordable repair
These are commonly used in budget smartphones or older models, where OLED is not required.
Essential Screen Replacement Parts
When performing screen repairs, the following screen repair parts may be required:
Display panel (LCD/OLED)
Touch digitizer
Glass lens
Frame/bezel
Proximity sensor mesh
Front camera bracket
Some screen repair sets LCD screen come pre-installed, while others require separate installation.
OEM iPhone Screen vs. Copy Screens
The genuine iPhone display is built to Apple’s exact specifications, offering:
True color accuracy
3D Touch compatibility
Face ID support
Longer lifespan
On the other hand, aftermarket or copy screens may be:
More affordable
Less bright or slightly off-color
Incompatible with advanced features like Face ID or True Tone
Face ID Compatible Screens
Some third-party screens do not support Apple’s Face ID, leading to:
Disabled facial recognition
Pop-up warnings
Reduced user experience
Always opt for a Face ID-supported display if your device uses facial recognition. These parts are calibrated to match the device’s secure enclave and ensure smooth biometric performance.
Incell Screen Technology
An Incell LCD panel integrates the touch digitizer and LCD into a single layer. Advantages include:
Thinner design
Lower weight
Improved response time
Lower production cost
Used in many mid-range phones, Incell displays offer decent performance at a lower price point than OLED.
How 3D Touch Works
The 3D Touch screen was introduced by Apple, allowing users to:
Press deeper for more options
Preview content without opening
Access shortcuts and hidden menus
When replacing a 3D Touch screen, use compatible parts to retain this feature. Many aftermarket screens don’t support 3D Touch, affecting usability.
