During 2014 Samsung started to label their PVA panels as SVA, although the definition is currently unknown. In fact these are probably the only remaining mass-produced PVA panels on the market. Little information is available regarding any possible changes although we expect some improvements to response times and contrast ratios. We believe PSA has been used for these panels as well, much like AU Optronics have used it for their more recent AMVA generations. PSA is a process used to improve cell transmittance, helping to improve brightness, contrast ratio and liquid crystal switching speeds.
