Introduction

Ever wondered why two replacement screens for the same phone can have such different prices? Or why some screens feel brighter and more responsive than others? The truth is, not all smartphone screens are created equal. Depuis LCD contre OLED à OEM vs refurbished screens, knowing the difference can save you money, prevent frustration, and help you choose the right repair option.

Basics of Smartphone Displays

A smartphone screen is more than just a piece of glass. It’s made of layers that include:

• Display panel – shows images and colors.
• Touch digitizer – detects your finger movements.
• Glass protection – keeps everything safe.

When one of these breaks, repair options differ depending on the damage.

What is an LCD Screen?

LCD (Affichage à cristaux liquides) is one of the oldest but still widely used screen technologies.

• How it works: LCD screens use a backlight that shines through liquid crystals to produce images.
• Pros: Abordable, durable, good brightness.
• Inconvénients: Limited contrast, thicker design, weaker blacks.

What is an OLED Screen?

Oled (Diode électroluminescente organique) is a newer, more advanced display type.

• How it works: Each pixel emits its own light, no backlight needed.
• Pros: Noirs profonds, couleurs vibrantes, thin design, power efficient.
• Inconvénients: More expensive, risk of screen burn-in.

Key Difference Between LCD and OLED

• Light-emitting principle: LCD relies on backlight, OLED pixels glow individually.
• Color accuracy: OLED offers richer, more vivid colors.
• Brightness and contrast: OLED achieves infinite contrast; LCD is limited.
• Power use: OLED saves more power on dark screens, LCD consumes more consistently.

Think of LCD like a flashlight shining through colored paper, while OLED is like tiny glowing stars on a black sky.

Original Manufacturer Screens (OEM)

OEM (Fabricant d'équipement d'origine) screens are made by the same factory as your phone brand.

• With frame: Easier to install, higher cost.
• Without frame: Moins cher, requires skilled installation.
• Pros: Best quality, perfect fit, long-lasting.
• Inconvénients: Cher.

Refurbished Screens: What Are They?

A refurbished screen is usually an original display that had its outer glass replaced.

• The inner LCD or OLED panel remains the same.
• Quality depends on the repair process.

If done professionally, refurbished screens can work almost like new.

Re-glass/After-pressed Screens

This type involves only replacing the broken outer glass, keeping the old display panel.

• Pros: Cheapest option.
• Inconvénients: High chance of issues like bubbles, weak adhesive, or touch sensitivity loss.

Imagine putting a new windshield on a cracked car frame—it looks good at first but might not hold up.

Assembled Screens

Assembled screens are built from parts of different origins. For example, a generic LCD panel with a low-cost digitizer and glass frame.

• Caractéristiques: Lower price, inconsistent performance.
• Warning signs: Color mismatch, poor brightness, delayed touch.

Visual Cues for Identifying Screen Types

• OEM screens: Perfect alignment, natural colors, smooth touch.
• Remis à neuf: Small signs of rework, like glue residue.
• After-pressed: Tiny bubbles or dull touch.
• Assembled: Slightly different frame shape or thickness.

Risks of Using After-pressed Screens

• Air bubbles forming under glass.
• Touch not responding properly.
• Screen peeling off after a few months.

Tips to Identify Original vs Re-glass Screens

1. Check packaging – OEM comes sealed.
2. Look at frame – originals are seamless.
3. Inspect touch – no lag, no dead spots.
4. Factory logos – often missing in copies.

Price Difference Explained

• OEM screen: Highest price, best reliability.
• Refurbished screen: Mid-range, good compromise.
• After-pressed/assembled: Cheapest, risky long-term.

You’re basically choosing between premium, balanced, or gamble.

Practical Advice for Consumers

• If you want long-lasting reliability, go OEM.
• If you want budget-friendly but decent quality, consider refurbished.
• If you want the cheapest fix, be ready for compromises with after-pressed screens.

Always ask repair shops: Is this OEM, remis à neuf, or assembled?

Conclusion

Your phone screen isn’t just a piece of glass—it’s the window to your digital life. Knowing the difference between LCD, Oled, OEM, remis à neuf, and after-pressed screens helps you avoid scams and make smarter choices. Remember: a screen that seems cheap today might cost more in headaches tomorrow.
