Advance the State of the Art in OLED Displays

This project creates a new type of OLED display pixel circuit incorporating pulse width modulation (PWM) brightness control utilizing Amorphyx's patented amorphous oxide semiconductor TFTs and quantum tunneling switch AMNRs. This pixel circuit  enables increased variable image refresh rate  performance that reduces mobile device power consumption by more than 50% while increasing display image quality for gaming and video entertainment and dramatically reducing display cost. 

Apple and Intel are now driving the expansion of variable image refresh rate from premium smartphones to the premium laptop market.  This requires new display manufacturing factories incorporating previously unproven display technologies.  This PWM pixel circuit promises to be one of the technologies for enabling this expansion.

This project is designed as an applications and design project - starting from an initial idea and ending with a final product. The initial layout will begin with literature review and end with simulations of a new circuit design; however, if time permits experimental circuits will be fabricated and tested with the option for publication. 

All performance measurement work will take place in the Materials Science lab in Owen Hall on OSU campus.

 

Objectives


The ultimate deliverable is a set of circuit simulation results that verifies a PWM-based OLED pixel circuit meeting the necessary performance specifications.

Students will be expected to: create a project breakdown and timeline once literature review is complete, split tasks amongst themselves and hold each other accountable, meet as a group weekly for updates and planning, and reach out for assistance when needed.

Motivations


You are an electrical engineer who enjoys designing analog electronics focusing on clever circuit implementation using a small number of devices.  This kind of design differs from digital electronics in that it requires a deeper understanding of how transistors function and how to use them in both linear and saturated regions.  You will be integrating a circuit that controls the brightness of an organic LED - a circuit replicated millions of times across each display.  Consistency of performance and the impacts of thin film materials variations play key roles in crafting the circuit.

Qualifications


Minimum Qualifications:

A basic understanding of how MOSFETs function (ECE322, 323)

PH211-213, CH201

Preferred Qualifications:

An interest in understanding how a transistor functions, how it is fabricated, and how to use simulation and electronic performance testing to define relationships between the two.  A passion for working from the concept level to the detail level.
