Seoul, Samsung Display, a major display panel maker in South Korea, has received approval from the US government to supply certain display products to Huawei Technologies, sources here said on Tuesday, amid Washington's sanctions against the Chinese tech giant.

Samsung Display recently acquired a license from the US Commerce Department to export some of its smartphone OLED displays to Huawei. Samsung Display is the world's largest smartphone OLED display supplier.

The US started to impose new export curbs on Huawei from September 15, citing national security reasons. The sanctions ban the supply of components made with US equipment, software and design to Huawei without prior approval from Washington.

The sources said Samsung Display is the first South Korean company to earn such approval from the US after Washington's restrictions against Huawei went into effect, , reports Yonhap news agency.

Its domestic rival LG Display and chipmakers Samsung Electronics and SK hynix have yet to receive export licenses from the US authorities, according to the sources.

Industry insiders said the US may have granted the license to Samsung Display since display panels are less sensitive products compared to semiconductors, as Huawei can secure displays from BOE Technology Group and other Chinese firms.

Intel and Advanced Micro Devices (AMD) have reportedly obtained licenses from the US government to supply their computer and server processors.

But since Huawei, the world's second-largest smartphone vendor, is struggling to get memory chips from major suppliers, industry insiders said it is doubtful whether Huawei would increase its display procurement.

"With chip supply to Huawei basically halted at this moment, it is impossible for Huawei to make smartphones only with display panels," an official with a local electronics firm said. "In order for Huawei to have stable production of its products, restrictions on chip exports should be lifted."
