LG makes significant improvements in UHD OLED panel yields

Over 65% now and 85% targeted by year end

by Mark Hodgkinson Jun 11, 2015


  • It is being reported in the Korean press that LG Display has managed to raise production yields for Ultra HD OLED panels up to 65%.
    As we know, LG is the pioneer in the domestic OLED TV market but difficulties in producing the panels has led to disappointing numbers of usable ones coming off the production lines; with resulting steep pricing at retail.

    According to the ET News, a high-ranking LG Display executive has said the yields in 65-inch and 77-inch UHD OLED’s recently surpassed 65%. They’ve done even better with Full HD panels but since the high-end market is being dominated by Ultra HD, it’s not particularly significant. The yield value of the 55-inch 4K OLEDs is believed to be even higher.

    It’s reported that the goal of LG Display, this year, is to increase the yield of 77-inch, 65-inch, and 55-inch UHD OLED panels’ up to 87%, 85%, and 75%, respectively, and if they are able to succeed in reaching that, they will then invest in building production facilities to double the current output.

    LG is currently developing an ink-jet technique which, if successfully deployed on a mass-production line, they are hoping will raise yield values and greatly lower production cost. But to raise OLED TV’s total yield value, LG also needs to improve yield values of the modules, which are still low.

    Apparently, LG is currently struggling with modules yield values because of voltage problems. A source told ET News that LG’s goal is to improve module’s yield values up to more than 95% by end of the year.

    Clearly, if LG can reach their targets in their projected timelines, we should see some significant downward movement on UHD OLED TV pricing before too long, which has to be good news!
