September 19 news, according to foreign media reports, according sources, Samsung’s system LSI business unit plans to get more OLED display driver chip capacity from UMC next year, because its main customers have high demand for the product.
According to foreign media reports, OLED display driver chips are not only used in mid-to-high-end mobile phones but will also penetrate into more applications such as pens and TVs.
At present, there are not many manufacturers in the world that can produce OLED display driver chips, including TSMC, Samsung Electronics, UMC Electronics and Grosvenor.
In June 2021, the research institute said that OLED display driver chips are currently mainly manufactured using 40nm and 28nm process technology.
Today, foreign media reported that UMC has a 12-inch wafer production line that produces chips based on the 28nm process.
In addition to OLED display driver chips, UMC also OEMs CMOS image sensors for Samsung. In April last year, foreign media reported that Samsung and UMC had signed an image sensor foundry agreement.
In March this year, industry sources revealed that UMC and Samsung had agreed on a higher offer for a new long-term foundry contract.
