VA technology vs. IPS technology
VA technology with IPS technology
Production of LCD panels are made of different technologies.
1 - TN cheapest technology
2 - Average cost of VA Technology: Samsung
3 - The most expensive IPS technology: LG
Cheapest TN panel actually uses the technology of the oldest and most expensive
IPS panel technology and its uses.
The original panels technology (Twisted Nematic) due to the configuration of molecules
Christelle fluid problems such as limited viewing angle and color abnormalities
seen Be.
These problems were lower in VA technology but disappeared. Samsung Again
using SPVA technology to produce better color and viewing angle step Harvest
but no form of the IPS technology that LG PHILIPS Uses are not.
VA Limits viewing angle technology in comparison with other technologies
is quite visible in Fig.
Imagine the image you see on your LCD and middle column Be.If you want to
display a little place nearby images left or right panels (IPS) which are
built on LG's picture does not change, but right panels (VA) that Samsung
have made a change.
VA panels next problem is the problem of response time. In response, the
VA panels and Again it is derivative of IPS panels. Since firms Apple Iphone
and Ipod like such a big production because of better response time IPS
panels are using false propaganda from manufacturers VA Panel about 1 millisecond
response time is quite as abnormal A. Below compare the response time of
the LG IPS Panels and Panel VA As you can see from Samsung.
As shown in the left image (IPS from LG) see action films An event in which
the rate of change is high on the left panel without vibration Is observed,
whereas in the right panel (VA from Samsung) because response time Weaker
tremors and residual images together with previously seen images.
The next issue is the sensitivity to shock.
In panels (IPS) liquid crystal molecules because of the shape of the pressure
on the panel to the lighting and color
But this would not change the page in panels (VA) on defects in their shows.
The flaw in this film is seen as a waste of previous images.
In addition, due to the complexity of the technology used and its advantages
over other producers panel, IPS panels are more expensive than VA panels.
