  1. Problem Statement Technical Approaches Results and Outcomes • Current backlights are heavy and expensive • Using buckypaper we can create a planar light source, which will make many heavy/costly components in backlights obsolete, however a high vacuum is needed to maintain electron field emission. • Laser treatment process “activates” buckypaper Field Emission Display Using Buckypaper • Reduces weight of chamber by 83% • Sample Prototype • The empty space between the two electrodes must be under a high vacuum to maintain field emission. • Holds a satisfactory vacuum level for 2+ hours Project Objectives • Learn laser post-treatment process and backlight packaging techniques • Develop two ideas for possible vacuum chambers that are • Light for portability • Hold a high vacuum • Transparent section for viewing Matthew Hoza • Pixilation Uniqueness ITO Glass ITO Glass Phosphor Phosphor • Laser irradiation is selected to assist nanotube activation • Power saving buckypaper is expected, with a turn on field lower than 0.5 V/μm Buckypaper ITO Glass The new vacuum chamber allows us to give a demonstration without constant vacuuming.
