Advanced edge field Switch (Wide viewing Angle)
This is LCD technology from IPS Boe Hydis North Korea. Until 2003 known as Edge Field Switching (FFS), the advanced technology accompanying field switching was IPS or S IPS that provided superior performance and high brightness similar to skin color gamut. By optimizing the white gamut, the enhanced white/gray propagation also corrects the bias caused by color shifts and light leaks.
