Different types of Flexible display technologies
Based on either reflectivity emissivity; There are two forms of display
- Flexible E-Paper based display
- Flexible LED-based display
Construction of E-paper Display
It has two different parts
- Trent plane
- Backplane
The front plane consists of E-ink, The backplane consists of an electronic circuit to form an E-ink electronic display the ink is printed onto a plastic film that is laminated to a layer of circuitry.
Functionality
The new paper phone is made up of two layers. The E-ink display and a flexible printed circuit with bend sensors are flexibly printed with a resistive bend circuit which is used to identify the bending of the Display screen. The user actually chooses the function by bending the PCB.
Structure of OLED
- Substrate
- Anode
- Cathode
- Conductive layer
- Emissive layer
Working of OLED technology
A voltage is applied across the OLED such that the anode is positive with respect to the cathode current flow from the cathode to the anode through the organic layer then the electron and hole are compiled together and emit light
Flexible OLED
A flexible OLED incorporating a flexible plastic substrate on which the electroluminescent organic semiconductor is deposited.
Applications
- Cell phones
- Lighting
- TV
- large displays
