Ningbo Exciton Technology

What Ningbo Exciton Technology does

Ningbo Exciton Technology is a Ningbo-based, publicly listed (Shenzhen ChiNext, ticker 300566, IPO November 2016) manufacturer of optical and functional films with an integrated technology platform spanning resin formulation, micro-replication, and precision coating (micro-gravure, slot-die, comma blade). Its products are organized into four business verticals: optoelectronics (optical diffusion films, brightness enhancement/prism films, composite films, quantum dot films, LSR reflectors, naked-eye 3D grating films, and education-machine protective films for LCD backlight modules); photovoltaic (solar backplane films and solar encapsulant films via subsidiaries Jiyang New Energy and Anhui Exciton); automotive (PDLC smart dimming films for sunroofs, UV-blocking window films via Ziguang Technology, and decorative films); and battery (auxiliary materials, die-cutting services, and lithium manganese iron phosphate cathode materials via Hengchuang Nano).

The company employs fewer than 800 staff including 13+ PhD holders and runs manufacturing across multiple production bases in Ningbo (Gaoxin, Jiangbei, Xiangshan) and Anhui (Lu'an). It is the only domestic Chinese optical film company with full independent intellectual property for LCD optical film R&D and production, and optical diffusion film shipments rank #1 globally. Revenue model is B2B hardware sales of films directly to enterprise customers — predominantly global tier-1 consumer electronics (Samsung, LG, BOE, Huawei, Xiaomi, Hisense, TCL, Skyworth), photovoltaic module manufacturers (Tongwei, Jinko, LONGi, Risen), and automotive/display customers — through regional sales offices in Suzhou and Shenzhen. Pricing is not publicly disclosed and is negotiated per contract.

Disclosed revenue grew from 610 million RMB (2016) to 1.42 billion RMB (2020), with 2021 Q1–Q3 revenue of 1.333 billion RMB (+35.62% YoY). The company holds 196 patents (150 Chinese invention patents, 6 foreign, 40 utility model) as of end-2024 and has led industry standards including HG/T 5507-2018. Multiple national recognitions apply: National Manufacturing Single-Champion Demonstration Enterprise (2017), National Technology Innovation Demonstration Enterprise, National Green Factory (2022), and National Intellectual Property Demonstration Enterprise. Strategic shareholder Xiaomi invested in 2021 alongside a 700 million RMB private placement, deepening the supply-chain partnership.
