DisplaySearch estimates that 35,200 OLED TVs were sold, globally, in the first quarter of 2015. This is a seven-fold increase from Q1 2014 (4,600 units). DisplaySearch says that the OLED TV market will grow from around 400,000 in 2015 to 7 million in 2019.
The current 35,200 estimate is actually lower than DisplaySearch's previous estimate of over 53,000 OLED TVs in the quarter. LG themselves aim to produce around 600,000 OLED TVs in 2015.
Out of the 35,200 OLEDs sold in the quarter, 31,200 units (89%) were sold by LG Electronics. The rest were sold by Skyworth (2,300), Hisense (1,100) Konka (1,100) and Changhong (100). All of these Chinese-based TV makers use panels produced by LG Display (which commands 100% of the OLED TV market).
Interestingly this is the first time we hear that both Konka and Hisense has commercial OLED TVs in the market. Konka did unveil their first 65" 4K OLED TV product earlier this year, but I was not aware that it was shipping yet.
