AI Thread Summary
The discussion centers on simulating an OLED using Atlas Silvaco and the challenge of converting light power (watt/um) into luminance (cd/m2). Participants note that watt/um is not a valid unit for luminance and emphasize the need for integration over the visible spectrum to achieve the conversion. A suggested resource for this conversion, https://app.knovel.com/uc/, is reported to work for some users but not for others, leading to speculation about regional internet issues. The conversation highlights the complexities involved in the integration process within Atlas Silvaco. Overall, the thread illustrates the technical difficulties in performing accurate simulations and conversions in OLED modeling.

I am trying to simulate an OLED via Atlas SilvacoI want to know how to convert light power (watt/um) into luminance (cd/m2) or the syntax to do that in Atlas silvaco.THANKS

Once you get the units straightened out (watt/um does not appear to be a valid unit of luminance), try this site:
https://app.knovel.com/uc/

(unless that "um" term is micron, indicating wavelength. then you need to specify the bandwidth to get the total power. rather a can-of-worms i would say)

Cheers,
Tom

Thank you for your reply
this site did not work (https://app.knovel.com/uc/)
for the conversion there is an integration over the wavelength which must be carried out over the visible spectrum. but I can't insert this integration into the Atlas Silvaco code!!!

Site works fine for me using Google Chrome in Windows 10 Home.

Works for me as well with Windows 10 and Firefox.

@halaoui12 -- maybe some Internet problem with some blocking by your country?

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
