What's the difference for Orange 4K? Why Subpixel is BETTER? If we upgrade the 2K LCD screen to a higher resolution for 4K, the pixel size will be driven down to 31.5um. Furthermore, if a pixel can be divided into 3 subpixels, the resolution in one direction will be as fine as 10.5um, which is a dramatic improvement over the 2K LCD screen. Compared with a Normal 4K Mono ScreenO4K is X3 in pixel numberO4K is a higher precisionNormal 4K is a 5.5-6.6 inch mono screen without subpixel in comparisonCompared with a Normal 2K Mono ScreenO4K is X6 in pixel numberO4K is X6.7 higher in precisionNormal 2K is a 5.5-6.1 inch mono screen without subpixel in comparison What's the BENEFIT of subpixel? With the algorithm embedded in Longerware and firmware, the UV exposure through each subpixel will be controlled accurately to deliver final 3D models with ultra-smooth surfaces and ultra-fine details.
