Take a look at the best projectors 2021: Full HD, 4K, portable, short throw.Each panel has 4096 x 2160 resolution to deliver a full 8.8 million pixels for native 4K. There are three SXRD panels in each machine, one for each of the primary colours (red, green and blue) from which all the other necessary colours can be made. That way, the image benefits from both the deep blacks, and therefore high contrast, as well as fine detail too. A layer of liquid crystal sits on top of a reflective surface and the tiny gaps between the liquid crystal cells allow tight control of the reflected light that passes through. It's an LCoS projection system (liquid crystal on silicon). The Sony SXRD panel aims to capture the best of both of these technologies. The disadvantage is that DLP projectors aren't always quite so sharp at the same resolution. Each micromirror represents an individual on-screen pixel and each can be angled so as not to reflect any light at all, therefore creating far better black depth. Light from the laser or lamp source is bounced off these to create the picture rather than passed through the panel. Reflective panels, the most popular being the Texas Instruments DLP chips, are covered in a series of micromirrors. As with LCD TVs, the major downside is that it's hard to produce proper blacks with the constant backlighting. Transmissive panels involve shining a light source through, usually, a set of LCD crystals to make an image – much like an LCD TV. It's where the pixel information comes from.Ĭheaper, non-native 4K panels are usually one of two main types: transmissive or reflective. It's the place where the image is formed before it's focused by the lens and onto the screen. The cornerstone of Sony's native 4K projectors is the SXRD projector panel system.
