AMOLED и IPS-дисплеи

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 и 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 devices, и premium consumer electronics.

AMOLED vs IPS: A Side-by-Side Comparison

Характеристика	AMOLED Display	IPS Display
Light Source	Self-emissive pixels	Requires LED backlight
Коэффициент контрастности	Very high (true black)	Moderate, backlight limits contrast
Яркость	Moderate, varies by brand	Generally brighter, consistent
Цветовая точность	Vivid colors, sometimes oversaturated	Accurate, natural tones
Power Usage	Lower on dark backgrounds	Higher across all images
Срок службы	Limited (organic material degrades)	Longer, especially in static displays
Стоимость	Higher due to complex manufacturing	More affordable, widely available
Design Flexibility	Thin, flexible, foldable	Rigid, thicker with backlight
Best For	Smartphones, wearables, premium tablets	Medical, industrial, long-use environments

Pros and Cons of AMOLED Displays

✅ Advantages

• 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

✅ Advantages

• 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
