UBI Research is tracking the price of premium TV sold on Amazon.com in the US. As competition intensifies, the price gap between OLED and LCD TVs keeps getting lower - to the point where is not much difference between a high end Samsung QLED TV and LG's OLEDC7 OLED TVs.
In December 2016, the price gap between a 65" LG OLED TV to a 65" Samsung SUHD TV was about $1,000. The price gap as of today is only about $300. The price gap for a 55" TV is even lower (around $200).
Sony's XBR-A1E OLED TV still carries a premium over LG's OLED C7, but its price dropped by over $2,000 (55") since its introduction in March.
Earlier this month IHS estimated that production costs of 55" 4K OLED TVs have declined 55% from the beginning of 2015 to Q2 2017. IHS estimates that it costs $582 for LGD to produce a 55" OLED panel, and the price will continue to drop to reach $242 in 2021.
