Currently, Samsung Display dominates the supply of AMOLED displays, but it does not allow its driver chip suppliers, Samsung Semiconductor and MagnaChip, to release AMOLED driver chips to other panel manufacturers. As the capacity of Chinese AMOLED panels grows, non-Korean driver chip manufacturers are beginning to emerge. Raydium, Novatek, and MediaTek are the major driver chip suppliers for Chinese AMOLED panel manufacturers. For example, starting in 2018, BOE used Novatek’s driver chips to supply the Huawei Mate 20 Pro model, and in the first quarter of 2019, BOE used MediaTek’s driver chips to supply the Huawei P30 Pro model. Raydium has also maintained a significant market share alongside Huayi and Visionox.
Previously, Nubia released the Z20 model, featuring dual-sided flexible screens, supplied by BOE, with sizes of 6.42” FHD+ and 5.1” HD+. The 6.42” FHD+ uses driver chips from Beijing Yiswei ESWIN, while the 5.1” HD+ uses driver chips from Raydium. Beijing Yiswei ESWIN is a mainland China driver chip design company, with strategic investment from BOE, focusing on semiconductors and materials.
In addition to Beijing Yiswei ESWIN, there are other driver chip design companies in mainland China developing AMOLED driver chips, notably Zhongying Electronics (subsidiary Xinying Technology), Beijing Jichuang Northern, Geko Micro, Xinxiang Micro, Jingmen Technology, Shenzhen Yunying Valley, Shenzhen Jidis, and Guangdong Shenghe Micro.
