Helfrich and Schadt at Roche in Switzerland experimented with electric fields parallel to the glass substrates of LCDs at the time. The inventors at the Fraunhofer Institute in Freiburg, Germany, came up with an IPS implementation patented

The section on "Advantages" reads like an advertisement written by someone who is still learning the
English language. Some of it is truly incomprehensible -- copy-editing would be futile. Why is there no corresponding section on disadvantages? Even better would be a table comparing the strengths and

Define viewing-angle. The angle at which you can SEE the screen? Sure that might be 178 degrees. But there is a noticeable change in color quality beyond 90 degrees on ANY IPS display. The problem with

It relies on jargon which is not defined anywhere else in

There is good reason why so many Asian companies took a license from Merck (German patent mentioned) to manufacture IPS LCDs. Multi-domain arrangements such as in the Yoo et al. patent were an improvement. However, I cannot spend the time to research, whether the Yoo et al patent was decisive.
235:
The Super PLS section looks like it was written by a
Samsung PR person with no technical knowledge - supports "resolutions of up to almost 1 megapixel" and doubles viewing angles (which are already quoted at 178 degrees) are the most egregious examples of someone talking out their arse.
427:
South Korean patents/improvements of IPS technology were after
Japanese patents/improvements as seen in the article with tables for Hitachi and LG. If you want to include South Korean inventions as a category, the historically correct sequence would be: German, Japanese, South Korean.
292:
After reading this article and the comments on the talk page I have made an effort to draw a schematic and add an explanation of a particular type of IPS operation closest related to twisted nematic LCDs. A lot of details are left out for a better understanding of the basics.
505:
The chart in the history section is beyond useless. It really does reek of marketing PR (notice all the quantify tags?). I'm tempted to remove it, but wanted to post here first to see if any of the editors are still active here and would like to propose an alternative first.
272:
Parts of this article appear to be verbatim copies or very close paraphrases of portions of the source texts they cite. While it is good that the sources are credited, these really need to be rewritten in original prose if this is in fact the

context? parallel to the glass front of the monitor? parallel to the table the monitor rests on?), and perhaps two schematic diagrams showing how the electrodes and wiring differ from those in ordinary TFT TN monitors.

First of all, that source does not even say that!!!!! It says that VA has "wider viewing angles than TFT". NOT compared to IPS. Secondly, one of the amazing hallmarks of IPS (all flavors) is the enormous viewing

I don't know enough to fix it, and what it really needs is to be deleted and started from scratch! I'll see if I can find someone who can re-write it, but, if there's anyone else out there who can, please do so!
641:
The books links don't have pictures (I don't think). The article has a picture (Figure 6), but it's behind a paywall. So we're left with a picture from a manufacturer website. Anyone have any better idea?
543:
As a matter of fact, I'm tempted to just completely re-write the whole article from scratch, and then copy it over this one... if I can find an editor or two to help, maybe we can start it over at

In the section on "History" only the 1st, 2nd, and 4th sentences actually touch on history. Not a word in this section about the men and women, and companies, that invented and developed IPS.

However, a similar effort is still needed to explain super IPS and other more advanced versions. I have left LCD R&D in 1980. Therefore, I am not an expert on the later evolution.
