<p>I am not an expert by any stretch but I hope this helps, but these are regular old TFT LCD screens. You can even get 4K ones and use them for the same process. You can for example pick up 4K displays such as the H546UAN01.0 and do the same with them. </p>

<p>I'm doing some research on what types of LCD displays can be used to filter and pass UV light for resin curing - specifically in the context of building a DIY 3D SLA printer.</p>

<p>The community commonly uses the Sharp LS055R1SX03 module.
