I'm still confused on this. The Anycubic Photon Ultra is coming out soon, and it features an internal 720p Projector. The 720p resolution seems like a far cry from a 2k LCD (1280×720 vs. 2560x1440). Despite having 4x as many pixels, many articles are praising DLP as being much higher in resolution / detail. This is very counterintuitive... How can a DLP projector with less pixels produce a more detailed item than a 2k LED exposure?
How can a digital camera produce images several times the resolution of the sensor? They move the sensor and overlay multiple exposures. Optically or physically moving the DLP chip or its projected image can give a combined "image" from multiple scans anywhere from 2x to several times the linear resolution of the DLP itself.
Such a print might be slower than an LCD, because of multiple exposures for each layer, but it might also be faster, because the light source can be far brighter than can be used with an LCD without damaging the liquid crystals themselvs.
