Founded in 1999 and transferred from KONEX to KOSDAQ in 2017, ELP Corp is a maker of display and semiconductor inspection equipment headquartered in Hwaseong, Gyeonggi Province.
Its core products are AMOLED and LCD panel inspection systems, spanning OLED pattern generators (PG), automated optical inspection (AOI), panel aging systems, touch testers and DeMura systems that cover the full inspection process from cell to module stages.
The company has stated that since 2014 it has effectively been the sole supplier of OLED panel inspection equipment to a major domestic customer known to be Samsung Display, a relationship rooted in its participation in localizing inspection equipment from the early days of that customer's OLED business in 2003.
It also supplies LCD module touch inspection equipment to another major customer known to be LG Display and has a history of transactions with overseas panel makers including China's BOE.
More recently the company has expanded into Micro Display and Micro LED equipment, adding pattern generators, AOI, EL/PL testing and optical testing systems for Micro LED, while also broadening into semiconductor package test systems and antenna-in-package (AiP) testers.
Companies commonly cited for comparison in this space include HB Technology, Nextin, APS Innovation, Donga Eltec and TSE. The company points to in-house equipment drive and control algorithm technology as a competitive strength.
It also operates a subsidiary in Suzhou, China to support overseas expansion, and its largest shareholder is the company's own CEO, who recently disclosed a modest increase in his shareholding.
