Écrans AMOLED ou IPS

What Is IPS Display Technology and How Does It Work?

IPS (In-Plane Switching) is a type of TFT-LCD display technology. It uses a liquid crystal layer controlled by thin-film transistors and relies on a backlight to produce visible images. The crystals shift orientation to allow light through or block it, creating colors via a color filter layer.

IPS Display Highlights

• Requires a constant backlight
• Produces accurate colors and high brightness
• Delivers stable performance and long-term reliability
• Used in monitors, medical displays, industrial screens

Because of its precise color reproduction and reliability over time, IPS is often found in critical environments like medical diagnostics et control interfaces where accuracy matters.

What Makes AMOLED Different?

AMOLED (Active Matrix Organic Light Emitting Diode) screens don’t need a backlight. Each pixel in an AMOLED panel emits its own light using organic compounds that glow when electric current flows through them.

This structure allows for:

• True black (pixels turn completely off)
• Ultra-thin designs
• Flexible or curved screen possibilities
• High contrast and deep colors

AMOLED is widely used in smartphones, wearables, foldable deviceset premium consumer electronics.

AMOLED vs IPS: A Side-by-Side Comparison

Pros and Cons of AMOLED Displays

✅ Avantages

• True blacks & infinite contrast: Pixels switch off completely in black areas
• Flexible design: Suitable for foldable or curved screens
• Energy-efficient: Especially in dark UI or standby modes
• Wider viewing angles: Color remains consistent from all directions

❌ Disadvantages

• Shorter lifespan: Organic pixels, especially blue, degrade over time
• Risk of burn-in: Static content can cause ghost images
• Higher cost: Due to complex materials and lower yield rates

Pros and Cons of IPS TFT Displays

✅ Avantages

• Superior color accuracy: Critical for medical, design, and industrial applications
• High brightness output: Ideal for use in bright environments
• Stable longevity: No organic material, resistant to burn-in
• Consistent viewing experience: Maintains image quality at wide angles

❌ Disadvantages

• No true blacks: Backlight always on, lowering contrast
• Thicker modules: Less flexible design for compact devices
• Higher energy use: Backlight draws constant power regardless of image content

Which Display Works Best for Your Industry?

When to Choose AMOLED

Opt for AMOLED if your product needs:

• A sleek or curved form factor
• Brilliant color and deep contrast
• Power savings in standby or dark-mode apps
• A premium aesthetic experience

Ideal for:
Smartphones, smartwatches, fitness trackers, foldable tablets

When to Choose IPS

Go with IPS when your application prioritizes:

• Color precision and consistency
• Long-term usage without degradation
• Brightness for outdoor or clinical settings
• Stable display with reduced maintenance costs

Ideal for:
Medical monitors, industrial HMIs, rugged tablets, automotive displays

Final Thoughts: AMOLED vs IPS—It Depends on the Application

Choosing between AMOLED and IPS displays isn’t about which one is better universally—it’s about which one suits your product best.

If you value style, flexibility, and rich contrast in mobile or consumer devices, AMOLED delivers a premium look and feel. If your focus is on reliability, color accuracy, and continuous use in tough environments, IPS remains the industry workhorse.
