15” and 15.6” LED Displays with IPS Technology
AbraxSys is Raising the Standard of its 15” and
15.6” LED Displays with IPS Technology
Baton Rouge, LA - AbraxSys announced today
that it is in the process of migrating all of its 15” (4:3) and 15.6” (16:10) LED-backlit LCD products to include
In-Plane Switching technology. This is a major move to continue offering the best technology and staying ahead of
the competition. This transition is expected to take place late second quarter 2015.
In-Plane Switching (IPS) was one of the first refinements to
produce significant gains in the light-transmissive characteristics of TFT panels. Jointly developed by Hosiden and
NEC, it is a technology that addresses the two main issues of a standard twisted nematic (TN) TFT display: Color
and viewing angle.
With IPS, the crystals are aligned horizontally to the screen
rather than vertically, and the electrical field is applied between each end of the crystal molecules – termed a
lateral electric field. In this way, the crystals are kept parallel to the the electrode pair, and thus the glass
substrate of the screen. The liquid crystal molecules are not anchored to the lower glass substrate, so move more
freely into the desired alignment.
In a TN TFT display when one end of the liquid crystal is anchored
to the lower glass substrate and a voltage is applied, the crystal compounds untwist, changing the angle of
polarisation of the transmitted light. A downside of basic TN technology is that the alignment of molecules of
liquid crystal alters the further away they are from the anchored electrode, turning at right angles to the
substrates. This impairs the flow of light causing diminishing contrast, brightness and colour definition at wider
angles to the screen. IPS improves viewing angles of TFT monitors considerably.
AbraxSys is a worldwide leader of Industrial, Rail type, Military
grade, and Marine type LCD Flat Panel Displays, Panel PC, Sunlight & Daylight Readable Technology,
Fully-Enclosed Touch Screen Computers and Workstations.
