Introduction:
• It is a form factor of the smartphone.
• This technology enables the users to fold their
smartphones.
• Comparatively less space is consumed.

Reasons for Selecting Foldable
Smartphone:
• Comparatively consumes less space compared with
traditional devices.
• Easy to carry.
• Looks attractive.
• Greater Entertainment.

Components of Foldable
Smartphone:
• Flexible OLED Display
• Polymer Screen
• Jointed Case
• Flexible metal or plastic components
• Flexible type of Batteries

Most Important Parts: I. Display
• Flexible display is required and for that flexible glass is
important.
• Polymer Screen is required.
• Strong material is needed for manufacturing of the glass
for holding the bend stress.
• Glass must be responsive to the touch.

Most Important Parts: II. Battery
• Normal batteries can be damaged and can catch fire in
case of bending.
• Galvanic cells, anode, cathode and the collectors need
to be flexible.
• Currently small size of flexible batteries are used in
many wearable devices.

Concept of Flexible
Smartphone
In the above prototype screen of the mobile phones can be
bend from the middle portion. For the ultimate flexible
smartphones phone can be twisted from any angle as per
the demand of the users.

Advantages of the Flexible
Smartphones
• Less energy consumed due to used flexible OLED
displays.
• Wider viewing angles for the consumers.
• Better contrast Ratio.
• Easy to carry anywhere.
• Can be mass produced inexpensively after proper
adoption.

Conclusion
• Flexible Smartphones is having great potential to
succeed in the market.
• It is currently one of the great digital innovation.
• Can provide suitable options to the customers to carry
large size of devices in very much compact device.
• Following this technology other flexible electronics
components can be introduced.
