FAQ
Questions about OLED Displays
1. What factors affect the cost of a custom OLED?
- Size & complexity: Larger or flexible designs increase costs.
- Resolution/pixel density: Higher specs (e.g., 4K) require advanced manufacturing.
- Material quality: High-end materials (e.g., anti-glare coatings) add to pricing.
- Minimum order quantity (MOQ): Smaller batches may incur higher per-unit costs.
2. How long does it take to produce a custom OLED?
- Lead time: Typically 4–8 weeks after design approval, depending on complexity.
- Prototyping: Sample production takes 2–3 weeks for verification.
- Mass production: Delays may occur for high-volume orders or specialized components.
3. Can I request a flexible or foldable OLED?
- Yes, but with limitations:
- Flexibility: Curved designs require specialized substrates (e.g., polyimide).
- Durability: Foldable OLEDs need reinforced layers to prevent cracking.
- Cost: Flexible/foldable options are 20–50% more expensive than rigid panels.
4.How is the reliability of custom OLEDs tested?
- Key tests:
- Lifetime testing: Accelerated aging (e.g., 85°C/85% RH for 1,000 hours).
- Mechanical stress: Flexibility/folding endurance (100,000+ cycles for foldables).
- Environmental resistance: UV exposure, humidity, and thermal shock testing.
- Performance metrics:
- Luminance retention: >90% brightness after 10,000 hours.
- Color stability: Delta E < 3 for consistent color accuracy.
- Supplier accountability: Reputable manufacturers provide test reports and warranties (e.g., 2–5 years).
