iPhone 20 leak: Apple may wrap the display around all four sides

Apple's iPhone 20 is tipped to feature a full surround display covering the front, back and sides with no visible bezels. The design hinges on Samsung developing OLED panels that bend at sharp 90° angles, while optical distortion, durability and antenna placement remain unresolved.

• Design merges front, back and side surfaces into one continuous screen
• Key enabler is Samsung OLED bending at 90° without losing quality
• Risks include optical distortion, fragile edges and antenna placement
• Quad-curved displays may arrive as an intermediate step
