Volba mezi LCD nebo OLED obrazovkou na iPhonu je víc než jen výběr displeje – jde o vyvážení toho, co je pro vás nejdůležitější.: visual quality, eye comfort, durability, and cost. With Apple gradually shifting its entire lineup to OLED, understanding the differences now becomes even more essential.
Let’s break everything down step-by-step so you can confidently make the right choice.
Understanding the Core Difference
What Makes LCD Work
LCD (Displej z tekutých krystalů) relies on a backlight panel that shines through layers of liquid crystals. These crystals bend the light to create images, but because the backlight is always on, even “black” pixels still leak a little light—making black appear more like dark gray.
How OLED Generates Images
OLED (Organic Light-Emitting Diode) takes a completely different approach: each pixel lights up on its own. When showing black, that pixel simply turns off—resulting in pure darkness and incredible contrast.
Backlight vs Self-Emissive Pixels
Think of it like:
- LCD = A room with lights always turned on, even if curtains block most of it
- OLED = A room where you can turn individual lights on and off
This single difference dramatically affects color, kontrast, battery usage, and durability.
LCD vs OLED: A Comprehensive Feature Comparison
Display Technology
- LCD uses a backlight + liquid crystals
- OLED uses millions of self-emitting organic pixels
Contrast and Black Levels
- LCD: Lower contrast, blacks look gray
- OLED: Pure black, infinite contrast
Color Accuracy and Vibrancy
- LCD: Natural, true-to-life colors
- OLED: Richer, more saturated, more eye-catching
Slimness and Flexibility
- LCD: Thicker due to backlight
- OLED: Ředidlo, bendable, ideal for edge-to-edge design
Power Consumption
- LCD: Backlight always on → higher power usage
- OLED: Dark pixels turn off → more power-efficient
Eye Comfort
- LCD: Often uses DC dimming → less flicker
- OLED: Uses PWM dimming → noticeable flicker for sensitive users
Durability and Burn-In
- LCD: Long lifespan, resistant to aging, no burn-in
- OLED: Organic materials age faster, burn-in possible
Cost and Repairability
- LCD: Cheaper to make and replace
- OLED: Fancier tech → more expensive repairs
Comparison Table: LCD vs OLED v iPhonech
| Funkce | LCD Screen | OLED Screen |
|---|---|---|
| Display Principle | Podsvícení + liquid crystals control light | Self-emissive pixels that turn on/off individually |
| Contrast & Black Levels | Lower, black appears dark gray | Extremely high, true pure blacks |
| Color Performance | Natural and accurate | Vibrant, saturated, high-impact visuals |
| Tloušťka & Flexibility | Thicker, cannot bend | Ředidlo, bendable, ideal for modern design |
| Power Consumption | Higher due to constant backlight | Lower, especially on dark mode |
| Eye Comfort | DC dimming, low flicker → more eye-friendly | PWM dimming → may cause eye strain |
| Lifespan & Burn-In | Long lifespan, no burn-in | Shorter lifespan, burn-in risk exists |
| Cost | Lower production and repair cost | Higher production and repair cost |
Why These Differences Matter
How Technology Influences Real-World Viewing
LCD screens may look softer and more natural, while OLED screens deliver intense contrast that’s perfect for movies, Fotografie, and games.
Why Black Levels Change Your Experience
Watching a movie on OLED feels like being in a theater: dark scenes stay truly dark. LCD can’t achieve this because the backlight never completely turns off.
How Screen Type Affects Battery Life
If you love dark mode, OLED can significantly extend your battery life because black pixels consume no power.
Eye Comfort and Long-Term Use
DC Dimming on LCD
LCD brightness adjusts smoothly, with minimal flicker—ideal for:
- long reading sessions
- office work
- sensitive eyes
PWM Flicker on OLED
Most OLED iPhones use PWM (Pulse Width Modulation), which rapidly flickers at lower brightness.
Who Should Avoid PWM Screens
If you experience:
- headaches
- eye strain
- dizziness
- visual fatigue
You may be sensitive to PWM, a LCD may be safer for your eyes.
Durability, Lifespan, and Burn-In Risks
Static Images and OLED Burn-In
Leaving the same image (např., navigation bar, app icons) for long periods can permanently mark OLED screens.
LCD’s Long-Term Stability
LCDs don’t suffer from burn-in and tend to age more gracefully, making them a solid long-term choice.
Choosing Based on Your Usage
For Media & HDR Enthusiasts
Vybrat OLED.
You’ll enjoy:
- hlubší černoši
- richer movies
- more immersive gaming
For Heavy Readers or Office Tasks
Vybrat LCD, especially if:
- You use your phone for reading
- Your eyes get tired easily
- You keep the screen dim at night
For Gamers
Both work, but OLED gives:
- better visuals
- faster pixel response
LCD gives: - no burn-in worries
For Budget-Conscious Buyers
LCD is more affordable in both upfront purchase and repair costs.
Apple’s Market Trend
Apple’s Move Toward Full OLED
Apple is transitioning all future iPhones toward OLED, thanks to:
- better design flexibility
- superior aesthetics
- higher premium value
Which iPhones Still Offer LCD?
These models use LCD:
- iPhone 11
- iPhone XR
- iPhone SE (2nd and 3rd Gen)
Older models may also include LCD, but availability varies by region.
Final Recommendation Framework
Ask yourself:
- Do I want the best possible visuals → OLED
- Are my eyes sensitive → LCD
- Do I need long-term durability → LCD
- Do I use dark mode often → OLED
- Am I concerned about repair costs → LCD
Your ideal screen depends on what you value most.
Závěr
Choosing between LCD and OLED on an iPhone is really about understanding your priorities. OLED delivers unbeatable visual performance and energy efficiency, while LCD offers comfort, durability, a cenovou dostupnost. With Apple quickly shifting its lineup to OLED, knowing the differences now helps you make a smarter decision before options become limited.
Whether you’re a movie lover, a heavy reader, or someone who simply wants the best balance of value and eye comfort, there’s a perfect display type for your needs.
Časté časté
