4. Different Types Of Flexible Display
Technologies
Based on either Reflectivity or Emissivity:
there are two forms of displays
• Flexible E-Paper based displays and
• Flexible LED based displays.

5. Construction of E-Paper
• It has two different parts
•Front plane
•Back plane
• The front plane consist of E-ink
• The back plane consist of
electronic circuits
• To form an E-ink electronic
display the ink is printed onto a
plastic film that is laminated to a
layer of circuitry

6. Functionality
• The new paper phone is made of two layers: the
e-ink display and a flexible printed circuit with
bend sensors.
• Flexible printed circuit with resistive bend
circuits, which are used to identify the bending of
the display screen.
• The user actually chooses the function by
bending the PCB

8. Working Of OLED Technology
• A voltage is applied across
the OLED such that the
anode is positive with
respect to the cathode.
• Current flows from cathode
to anode through the organic
layers.
• Electron and hole combine
and emit light.

9. Flexible OLED
• A flexible OLED is a
type of OLED
incorporating a flexible
plastic substrate on
which the
electroluminescent
organic semiconductor
is deposited.

14. CONCLUSION
• Flexible electronic displays have the opportunity to
revolutionize an Industry.
• Effort to understand the failure limits and
mechanisms have been gaining momentum.
• As the components and manufacturing processes of
flexible electronics mature, the concept of flexible
flat panel display will eventually become a reality.
