Discussion Overview

The discussion revolves around simulating an OLED using Atlas Silvaco, specifically focusing on the conversion of light power measured in watt/um to luminance in cd/m2. Participants are exploring the necessary syntax and methods to perform this conversion within the software.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant seeks guidance on converting light power (watt/um) into luminance (cd/m2) within Atlas Silvaco.
  • Another participant points out that watt/um may not be a valid unit of luminance and suggests that if "um" refers to microns, the total power requires specifying the bandwidth, complicating the conversion.
  • A participant mentions the need for integration over the visible spectrum for the conversion but expresses difficulty in incorporating this integration into the Atlas Silvaco code.
  • Several participants confirm that the suggested website for conversion works for them, indicating potential issues with access for others.
  • One participant speculates that the access issue might be due to internet restrictions in the original poster's country.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the validity of the units or the method for conversion, and there are differing experiences regarding the functionality of the suggested website.

Contextual Notes

There is an unresolved discussion regarding the integration over the wavelength and how to implement this in Atlas Silvaco, as well as the validity of the units being used for conversion.

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:

(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?
