The LED market has shown mixed results in different global regions recently. Stagnant LED shipment growth, and plunging sapphire substrate prices have brought related manufacturers operations under the market lime light.

Taiwanese sapphire manufacturer Tera Xtal Technology remained upbeat about claiming payment from the bankrupt U.S.-based MOCVD manufacturer GT Advanced Technology (GTAT), according to a UDN report. Tera Xtal held a press conference on Wednesday under Taiwan’s Gretai Securities Market request to explain to investors the impact from GTAT’s bankruptcy filing.
