Doosan Solus Sole Supplier of CPL to Samsung for the Galaxy S20
April 12, 2020

​Doosan Solus was the sole supplier of high-distortion CPL for the OLED panels fitted in Samsung’s Galaxy S20 series to help improve the energy efficiency by up to 7% of the flagship smartphones. With the deal, Doosan Solus is now more likely to take the lead in the CPL market, the sources added. For the previous Galaxy models, Samsung had used the CPL from both Doosan Solus and DS Neolux.  “There are certainly positive results from replacing the CPL material, but they can never compare with the effect of upgrading the TFT technology that can help improve the energy efficiency of the entire panel,” said one market watcher. On requests from their client Apple, both Samsung Display and LG Display are developing LTPO TFT technology. LTPO boasts an energy efficiency that is about 10-15% higher than LTPS. Apple first deployed the LTPO TFT from LG Display for its Apple Watch 4 in 2018. During this process, Apple was able to expand the size of the watch display by more than 30%. From: The Elec is South Korea’s No.1 tech news platform.
