Panel Type: TN vs IPS, PLS, VA

TN: (Twisted Nematic) panels were the first LCD panel type.
IPS: (In-Plane Switching) was created to address the shortcomings of TN panels. IPS panels seek to solve TN panels’ issues of poor color reproduction and viewing angles.
PLS: (Plane to Line Switching) are quite similar to IPS panels, so much so that they have the same advantages and disadvantages, with a couple extra minor advantages. PLS is produced by Samsung, who claims that compared to IPS panels, PLS panels have better viewing angles, a 10% increase in brightness, 15% decrease in production costs, increased image quality, and allow for flexible panels.
VA: (Vertical Alignment) panels offer a solid medium between TN and IPS panels. VA was created to combine the advantages of IPS and TN panels, and largely did, although they did so with some compromise.
