Overview

Display devices are composed of an array of organic light emitting diodes (OLED) in the form of pixels (red, blue, green). Such devices are present in various electronic appliances, including:

  • mobile phones
  • tablets
  • televisions
  • smart packaging products
  • wearable products
  • automobile dashing boards.

Currently, inorganic light emitting diodes (LEDs) control the display market, but this technology has some limitations such as:

  • high fabrication cost
  • larger area processing
  • limited to rigid products.

The next generation of devices are expected to be flexible and stretchable so they can be used for future rollable televisions and wearable products.

The active light emitting material plays an extremely important role in making them energy efficient at a lower cost. In order to fabricate such next generation display devices, the emitting materials needs to be:

  • highly fluorescent
  • brighter
  • printable (solution processable)
  • able to operate at lower voltages.

In this project, we will design, synthesize and characterize new fluorescent and brighter materials (molecular or polymeric inks) using organic synthesis protocols. These materials will be characterize using various techniques.

The project will focus on the development of blue, green, yellow and red emitters with appropriate energy levels. Such newly synthesized materials will be evaluated  in OLED devices using rigid and flexible electrodes deposited substrates using charge transporting layers.

Research activities

As part of the research project, you'll be involved in:

  • a background literature survey to understand the basic concepts
  • material synthesis and purification experiments in the chemistry labs
  • material characterization
  • data analysis
  • collecting the results
  • preparing the progress report.

You'll work with a highly multidisciplinary team, including:

  • chemists
  • physicists
  • engineers.

Outcomes

By the end of the research project, you'll have:

  • synthesized brighter fluorescent materials in organic synthesis laboratory
  • developed conjugated material synthesis knowledge
  • understood the OLED device component requirements for flexible display.

Skills and experience

To be considered for this project, you should have:

  • knowledge of organic synthesis and its characterization
  • a chemistry/material Science background with some basic physics knowledge
  • knowledge of organic, flexible and printed electronics.
