TOP Engineering was founded in 1993 and listed on KOSDAQ in 2003 as a maker of process equipment for semiconductors, displays, secondary batteries, and camera modules. Its headquarters and production base are in Gumi, Gyeongbuk, with an R&D center in Pangyo, Gyeonggi, and overseas offices in China and Germany.
Its core business is display panel equipment such as LCD dispensers, GCS, array testers, and cleaning equipment, with the dispenser holding roughly a 60% share and the number-one position, supplied to major global panel makers.
In 2014 the company merged with Elex, a display inspection equipment specialist, expanding into the module tester segment.
In 2017 it brought PowerLogics, a battery protection circuit (PCM) and camera module specialist, under its consolidated umbrella, broadening its footprint into the ES (energy solutions) and CM (camera module) businesses.
Subsidiary PowerLogics produces PCM, smart modules, battery packs, BMS, and ESS in its ES segment, and IT mobile and automotive camera modules in its CM segment.
Consolidated revenue is roughly 72% camera modules (CM), 18% secondary batteries (ES), and around 4% LCD equipment, meaning the subsidiary's results drive group-level performance.
In 2025 the company set up a US subsidiary to expand its global sales network, while competing against DMS and Avaco in LCD equipment and numerous small and mid-sized parts and equipment makers in secondary batteries and camera modules.
