LG Electronics performed an interesting test comparing an OLED TV to an LCD LED TV to analyse the physical and emotional responses of viewers. The test was done on identical twins in the UK (Henry and William Wade), which viewed a Game of Thrones episode on LG's OLEDE9 TV and an 2013 LG LCD LED TV.
LG used Realeye's AI platform to analyse the facial expressions, head movements and body language of the twins, in addition to their hear rate. LG says that the test revealed that its OLED TV held 25% more attention than its 2013 TV, and that happiness was three times higher. The LG OLED TV provided a 15% more intense experience from a positive emotional standpoint.
