The in-plane switching technology was created for designing screens for
liquid crystal displays and solve limitations of matrix LCD’s. With In-
plane switching technology the crystals in the LCD screen are aligned
horizontally instead of vertically within a lateral electric field. These
panels provide superior image quality along with wide viewing angles of
around 178 degrees. This quality makes them well suited for graphics design
applications as they require accurate color reproduction. Though
traditional LCD monitors are cheaper than IPS ones the latter are preferred
due to superior technology which gives better color display and viewing
angles. In recent years this technology has improved further and
manufacturers are producing superior IPS panels which respond faster and
also provide better contrast when compared to previous IPS variety.
The commonly used Twisted Nematic monitors use common LCD display with fast
response images and almost negligent ghosting during sports or playing
video games. The viewing angles of this technology are its only drawback as
images viewed at vertical angles are unclear and veer at extreme angles. As
Twisted Nematic can only display 70 percent of 24 color bit available in
graphic cards, the viewers are unable to enjoy full gamut of colors.
Creative professionals that depend on accurate displays for their creations
have to work on superior quality TN panels for better contrast and color
representation. The alignment of molecules in the liquid crystals of TN
diminishes color definition, contrast and brightness.
IPS display system was created to get rid of the flaws of TN screens with
regard to viewing angles and color reproduction. The early IPS panels
altered pixel direction within the display system by keeping them in
parallel instead of perpendicular to provide better viewing angle.
The biggest drawback of IPS displays is that their pixel response time is
slower than TN screen that occasionally leads to ghosting and blurry
images. IPS screens have superior display as it applies two transistors for
every pixel which increases transparent area of display. Due to this
technology IPS panels consume more electricity and are not used much in
regular laptops as it will increase battery consumption.
Since it was first introduced in 1996, IPS has undergone several changes
and technology has improved at a fast pace. Now transparent electrodes are
used which consume less power and produce smooth pixels for clear and crisp
images which can be viewed from all angles. The latest improvement is IPS-
Pro which is a highly advanced technique producing crystal clear images
that are required in professional settings like architecture, engineering
and medical fields. In fields like medical imagery and heavy engineering
where clarity of images is very critical this technology provides the right
contrast and colors.
An IPS monitor may be expensive but its superior viewing technology is
critical for certain applications. Due to cost challenges the demand for
IPS screens is limited to professionals in the fields of engineering,
medicine, graphic design, fashion industry and also in small screens like
mobile phones and hand-held cameras.
