In November 2018 it was reported that South Korean prosecutors indicted a group of 11 executives and employees of Korea-based Toptec, a Samsung Electronics supplier, accusing them with leaking Samsung's flexible OLED technology to Chinese display makers.

According to new reports from Korea, the South Korean government has now decided to restrict the export of OLED production equipment. Korea will designate OLED equipment as a "national core technology" which means that any export, acquisition or merger deals will require government approval. Under the current law, display panel design, process, manufacturing and drivers are already designated as national core technologies, and Korea wants to add production equipment as well to prevent another case like Toptec from happening.

South Korean prosecutors indicted a group of 11 executives and employees of Korea-based Toptec, a Samsung Electronics supplier, accusing them with leaking Samsung's flexible OLED technology to Chinese display makers. The group includes Toptec's president and managing director.

According to Nikkei Asian Review, the Toptec's executives supplied the stolen information to four companies in China - including BOE and CSoT. The cost of the information was 15.5 billion Won - or almost $14 million USD. Toptec produces display production automated equipment.

Motorola has been granted an interesting patent that aims to solve screen deformation with foldable displays. Motorola says that one of the issues with foldable displays is that they deform in low temperatures.

Motorola suggests using a temperature sensor that detects when the display is deformed, and then the hinge is heated so that the display is automatically corrected. This could be used to create foldable OLEd phones that bend both inward and outwards, and can work with more than one hinge (so that you can fold a display several times).

Universal Display announced that it has signed long-term OLED material supply and license agreements with Samsung Display. UDC will continue to supply its PHOLED phosphorescent OLED materials and technology to Samsung Display for use in its OLED displays. The agreements are scheduled to run through December 31, 2022, and may be extended for an additional two-year period.

UDC did not disclose the financial terms of these new agreements, but we do know that Samsung will pay a license fee throughout the agreement period. The previous UDC-SDC agreement ended on December 31st 2017, but for the past month and a half the two companies still conducted business of course as SDC's OLED production was not halted.
