IPS technology provides several advantages over VA panels for professional displays: 1. IPS panels are resistant to blackening defects when exposed to direct sunlight, while VA panels can develop blackening defects at surface temperatures over 75°C. 2. IPS panels do not experience moving image sticking when the touchscreen is used, while touching the screen can cause moving image sticking on VA panels. 3. IPS panels provide vivid images from wide viewing angles of up to 45°, whereas the image quality deteriorates significantly at wide angles on VA panels.

In public place, people watch displays at everywhere
As size of display becomes larger and larger,
you can recognize the IPS superiority better.
“..iPad is thin and lighter than any other net books,
and It’s got gorgeous 9.7inch IPS display,
super high quality display, and you get a great angle
of view as well”

5. Shineout Technology
The interference between reflecting external light and backlight reduces the quality
of pictures and readability. LGD improved it by applying Anti-Reflection Coating.
