Flexible OLED
An OLED display technology using a flexible substrate that can be bent; it is the core display material enabling the foldable form factor of foldable-screen smartphones.
Timeline (last 90 days)
The inner screen of a foldable phone typically uses a flexible OLED panel composed of multiple organic light-emitting layers, a thin-film encapsulation layer and a polymer protective layer, with an overall thickness of only about a few tens of micrometers.
Once microcracks penetrate the encapsulation layer, moisture intrusion causes light-emitting pixels to fail and black spots to appear.
Flexible OLED panels use thin-film encapsulation (TFE) with alternating multilayer inorganic/organic structures to block moisture and oxygen, but their barrier performance is inherently weaker than rigid glass encapsulation.
Current mainstream flexible OLED panels use polyimide (PI) substrates, which can achieve a bending radius of 1–3 millimeters.
The breakthrough in flexible OLED technology stems from Samsung Display's sustained R&D in the 2010s, which solved the waterproofing and anti-oxidation challenges of flexible screens through Thin Film Encapsulation (TFE) technology.
The current industry average yield rate for flexible OLED screens is approximately 60-70%, far below the 90%+ of traditional screens.
Flexible OLED uses plastic substrates instead of traditional glass substrates, protecting organic light-emitting materials through multi-layer thin-film encapsulation technology.
Foldable screen technology relies on the collaborative design of flexible OLED display panels and precision hinge mechanical structures.
Flexible OLED uses flexible polymer materials such as polyimide (PI) as the substrate, allowing the screen to bend without breaking, distinguishing it from the glass substrate of traditional OLED.
Flexible OLED screens account for approximately 35–40% of the total cost of a tri-fold phone, with a single screen costing as much as $150–$200.
