Hello! I am a computational biophysicist currently working on Fluctuating Finite Element Analysis at the University of Leeds, UK. You can get in touch with me at [email protected]. While you're here, please take a look at my CV and LinkedIn profile!

I was employed as an engineer for 15 months at Sharp Devices Europe, between Summer 2014 and Autumn 2015. My principal responsibilities were: designing tests for LED performance, writing software, web design and development, comptetitor product analysis, and writing manuals. You can read my reference on my LinkedIn profile.

Developing Better Tools for LCD Quality Control

Designing modules to house LCD screens is a surprisingly tricky and labour-intensive process. The tiniest error in the measurements or assembly can result in a pattern of light-and-dark patches on the screen, known as ‘mura’. How do you know if you’ve got it right? In this article, I’ll be taking a look at my experiences of developing software to analyse the uniformity of light produced by LCD screens, using nothing more than consumer-grade digital cameras and Python.

The Physics and Thermal Characterisation of Sharp LEDs

ledthermals

As you probably know, halogen light bulbs are incandescent: they produce light as a side effect of being heated up. Conversely, LEDs are semiconductor devices, and prolonged heat can be very damaging to them. LED devices tend to be cooled in a similar way to computer CPUs – using a thermal interface (like thermal paste) a heatsink, and sometimes a fan as well. However, the effectiveness of these cooling methods can vary wildly, depending on the operational limits of the LED and the type of thermal interface being used. In this article, I’ll discuss the experimental methods I designed to characterise the thermal performance of LEDs using a variety of cooling methods.

The Sharp Colour Science Tool

scct

One of my responsibilities at Sharp was testing and analysing the type and quality of light produced by LED devices using an integrating sphere. I developed a graphical tool in Python that would automatically interpret spectral power distributions, read metadata from files, compute a large variety of colour metrics, and automatically generate PDF reports.

I gave this presentation at the STFC in Harwell and at ARUP in London as part of the Engineering Development Trust’s ‘Future Industry Leaders Award’ competition. Although I didn’t win, I was offered a job as a result, which makes me feel better about not winning. This presentation focuses on how to design user experiences (UX) for highly technical websites, and why it’s important to do so.
