  Introduction • - OLED(Organic Light Emitting Diode) technology evolution: CRT → LCD → OLED → Flexible display • - Flexible displays allow bending, folding, rolling • - Applications: wearable, foldable, and rollable electronics
• 4.
  OLED Basics &Structure • - Layers: substrate, anode, organic layers, cathode, encapsulation • - Mechanism: Electroluminescence from organic emissive layer • - Benefits: high contrast, wide angle, self- emissive
• 5.
  OLED vs LCD •- OLED: no backlight, flexible, faster response, thinner • - LCD: requires backlight, rigid, slower • - OLED offers superior contrast and design freedom
• 6.
  What is FlexibleOLED? • - Built on flexible substrates (plastic, thin glass) • - Enables bending, folding, and rolling • - Requires new electrode and encapsulation materials
• 7.
  Challenges • - Bendingstrain reduces efficiency • - Moisture and oxygen sensitivity • - High material and fabrication cost • - Uniformity issues over large area
• 8.
  Materials & Processes •- Substrates: PI, PEN, thin glass • - Electrodes: graphene, metal nanowires, conductive polymers • - Encapsulation: thin film barriers • - Techniques: roll-to-roll, inkjet printing
• 9.
  Cost & Lifespan •- Cost driven by substrate and barrier films • - Lifetime limited by organic degradation and moisture ingress • - Improvement via encapsulation and stable organics
• 10.
  Manufacturing • - Roll-to-rollprocessing enables continuous production • - Reduces cost, increases scalability • - Challenges: maintaining alignment, minimizing defects
• 11.
