Flexible computer screen technology uses bendable materials like OLEDs or polymer-based LCDs mounted on substrates such as polyimide. These screens can be curved, folded, or rolled without damage, enabling innovative devices like foldable phones and wearable displays. Panox Display leverages advanced manufacturing with ultrathin encapsulation layers (≤10µm) to ensure durability across 200,000+ bend cycles, making them ideal for consumer electronics, automotive dashboards, and medical wearables.
What Is Tandem OLED & Why It’s Important
How do flexible screens maintain durability?
Flexible screens achieve durability through polyimide substrates and thin-film encapsulation. The substrate replaces rigid glass, while encapsulation layers (e.g., alternating organic/inorganic films) block moisture/oxygen. Panox Display’s proprietary multi-layer barrier coating reduces micro-crack propagation by 70% versus standard designs. Pro Tip: Avoid sharp creases below 2mm radius—this exceeds most screens’ minimum bend radius (3–5mm). Example: Samsung’s Galaxy Fold uses a 7.3µm polyimide layer rated for 200k folds.
What materials enable screen flexibility?
Key materials include OLED emitters, conductive polymers, and elastic substrates. OLEDs lack rigid backlights, making them naturally bend-friendly. Silver nanowire or PEDOT:PSS layers replace brittle ITO for touch functionality. Panox Display uses LG Chem’s CPI (Colorless Polyimide) films, which offer 92% light transmittance and a 500 MPa tensile strength. Example: LG’s rollable TV employs a CPI substrate that withstands 30k roll cycles.
| Material | Rigid Screen Use | Flexible Screen Use |
|---|---|---|
| Substrate | Glass (0.5mm) | Polyimide (0.05mm) |
| Conductive Layer | ITO (150Ω/sq) | Silver Nanowire (10Ω/sq) |
| Encapsulation | Glass Lid | Thin-Film (3µm) |
Are flexible displays compatible with touchsensors?
Yes, via flexible touchsensors using metal mesh or carbon nanotube films. These materials maintain conductivity when bent, unlike traditional ITO. Panox Display integrates projected capacitive (PCAP) sensors with <1ms response times, even at 180° folds. However, creased areas may suffer 5–10% sensitivity loss. Example: Huawei Mate Xs uses a metal mesh sensor rated for 100k folds. Transitionally, pairing with compliant adhesives ensures layer stability during deformation.

FAQs
No—damaged OLED emitters or cracked encapsulation are irreparable. Panox Display recommends screen replacements, as DIY fixes risk damaging internal layers.
Do flexible screens consume more power?
Not inherently—OLEDs remain energy-efficient. However, folding may temporarily increase power draw by 5–8% when refreshing split-screen content.
