Haesung Optics is an optical and electronic components maker whose core business is OIS (Optical Image Stabilization) actuators for smartphone cameras.
The company previously operated camcorder and digital camera lens and camera module businesses but wound them down amid declining competitiveness, shifting its structure to focus on VCM (voice coil motor)-based OIS operations, and strengthened related capabilities further with the Haehwa Vina acquisition at the end of 2023.
Development is handled at the domestic headquarters while actual manufacturing takes place at Vietnamese subsidiaries (Haesung Vina and Haehwa Vina), and a Tianjin, China unit supports quality management and after-sales service for local customers, forming a global production framework.
Major customers include Samsung Electronics' supply chain through Samsung Electro-Mechanics, and the company also supplies OIS actuators to module makers serving global smartphone brands such as Xiaomi, Vivo, Honor, and Google.
In February 2024 the company acquired a 50.1% stake in TKENS, an automotive lamp anti-fogging and dehumidification component maker, for roughly KRW3.6bn, entering the automotive electronics business as a way to reduce reliance on the smartphone cycle.
TKENS began mass production of an integrated headlamp dehumidification module for vehicles in September 2024, starting with a domestic premium automaker and pursuing expansion to global brands.
OIS actuators are becoming an essential component as smartphone cameras move toward higher pixel counts and adoption spreads from flagship to mid-range models, a market where numerous camera module and optical component makers such as Jahwa Electronics, MCNEX, Actro, Powerlogics, and Optron Tech compete.
Against this competitive backdrop, the company is pursuing automation investment to raise cost competitiveness and production self-sufficiency.
