COF Packaging Sees Demand Emerging For Automotive OLED Displays

COF packaging demand for automotive OLED displays has emerged, which may further tighten market supply as capacity expansion will remain quite limited in the short term, according to industry sources.

The sources said that OLED has become a new battlefield for Taiwan driver IC vendors including Novatek Semiconductor, FocalTech, Himax Technologies. They are teaming up with driver IC packagers such as Chipbond Technology and ChipMos Technologies to tap into the supply chains of OLED panel makers including BOE Technology, LG Display and Samsung Electronics.

Himax has recently started its shipments of auto-use OLED driver ICs and timing control ICs to BOE, which have all adopted COF packaging technology.

In fact, with all-screen design as a common spec for midrange and high-tier smartphones, the COF process has seen roust demand for packaging TDDICs, and the supply has become increasingly tight as Huawei has asked its Taiwanese backend partners to ready more inventories to cushion impacts from US sactions. Other China smartphone vendors such as Oppo, Vivo and Lenovo are also seeking more capacity support from Taiwan partners, industry source said.

Additionally, demand for COF to package driver ICs for large-size and UHD TVs are also mounting significantly along with the growing popularity for 4K and 8K TVs ahead of the 2020 Tokyo Olympics.

Chances will be great for COF service providers to raise quotes in the coming year, and quote hikes for tape COF, in particular, are very likely to appear in the second half of 2019 thanks to its greater difficulty in capacity expansion, industry sources commented.―Digitimes
