There have been reports that LG Display’s In Plane Switching (IPS) is better in display quality than the Vertical Alignment (VA) technology of competing companies such as Samsung Display or Sharp.
On August 29, LG Display tested the qualities of its IPS 84 inch UHD product against competing companies’ VA 85 inch UHD products with global US product safety testing and certification agency Intertek. The results proved that the IPS product provided better display quality.
The IPS technology has been chosen by all LCD panel production companies to minimize an LCD panel’s disadvantage of a screen looking different from different angles. The IPS technology has been competing against the VA technology.
Intertek tested for color difference, visibility, and gamma distortion, which evaluates how much change is observed to the color, contrast, and brightness aspects from the front and the side of the monitor, deciding resolution quality. As a result, the 84 inch UHD product using IPS technology had 65% less color difference, 94% less gamma distortion, and 73% higher visibility than the 85 inch UHD product using VA technology.
