Top 15 LED Screen Manufacturers & Suppliers in Seoul (2026 Guide)

Company Profile: Samsung Electronics, founded in 1938 and headquartered in Suwon in the Seoul Capital Area, operates one of the industry’s widest direct-view LED portfolios through its B2B display division. The signage range spans The Wall microLED family for premium indoor walls and the IAB and IFJ series for indoor and semi-outdoor applications, all documented on the company’s business portal. For Seoul buyers the practical strengths are service depth and product availability: the Korean domestic market is Samsung’s home market, so spare parts, firmware support and specification consultation sit close at hand. The trade-off is price and channel structure — displays are sold through corporate B2B and distribution channels at listed-manufacturer margins rather than factory-direct rates. Buyers comparing a fine pitch LED display program for a Seoul flagship store usually shortlist Samsung against LG and against Shenzhen import lines on total project cost.

• The Wall microLED — modular direct-view walls for premium indoor environments
• IAB series — indoor fine-pitch LED signage for corporate and retail
• IFJ series — semi-outdoor signage class for storefront and window builds

Strengths: Home-market service network across Korea; the industry’s broadest microLED line-up under The Wall; documented global installed base in broadcast and retail.

Limitations: Premium pricing relative to import lines; procurement runs through B2B channels with distributor margins rather than open pricing.

Premium listed-manufacturer pricing, quoted per configuration.

Enterprises, broadcasters and flagship retail operators in Seoul that want a single accountable brand with domestic service coverage.

The Wall installations across broadcast studios and retail environments worldwide; specific Seoul reference sites are quoted through Samsung’s B2B channels rather than published openly.

Company Profile: LG Electronics runs its business solutions operation from Yeouido, Seoul, and has pushed microLED further down the pitch ladder than most rivals: the MAGNIT line documents emitter pitches down to 0.9 mm in its LAEC015 model, alongside the LSCB series that pairs LED cabinets with the webOS signage platform. The company also supplies LED cinema screens, which gives it a credible path into Seoul’s post-production and screening-room segment. For buyers, LG’s positioning mirrors Samsung’s with one difference worth testing at quote stage: the webOS ecosystem can remove external media players in networked signage rollouts, which changes the wiring and maintenance plan. Pricing sits at listed-manufacturer levels, and large programs are quoted per site. Teams specifying a control room LED video wall for a Seoul operations center typically evaluate MAGNIT against fine-pitch SMD and COB imports on contrast, seam visibility and 24/7 duty ratings.

• LG MAGNIT (LAEC015) — 0.9 mm microLED signage for close-view indoor walls
• LSCB series — webOS-integrated LED cabinets for networked signage
• LED cinema display systems for screening rooms and post-production

Strengths: Documented 0.9 mm microLED pitch leadership; webOS platform integration reduces external hardware; Seoul-headquartered support organization.

Limitations: Premium pricing; the webOS ecosystem ties buyers to LG’s software stack, which can complicate mixed-vendor estates.

Premium listed-manufacturer pricing, quoted per configuration.

Broadcasters, cinemas, control-room operators and corporate estates standardizing on a managed signage platform.

LED cinema deployments and microLED signage programs worldwide; Seoul reference installations are disclosed through LG’s business channels.

Company Profile: d’strict, founded in 2004 and based in Sinsa-dong, Gangnam-gu, is the studio that turned Seoul’s LED surfaces into global media-art references — and it is a creative company, not a cabinet maker. Its WAVE anamorphic piece at COEX K-Pop Square, installed in 2018 on roughly 1,620 m² of LED, earned a Red Dot award and made the site Korea’s most photographed media facade; the studio’s work also includes the Ending Door walls at Incheon Airport T2, two media surfaces about 33 m wide and 5 m tall, and VERSE.SEOUL commissions at THE HYUNDAI SEOUL. For procurement purposes the role matters: d’strict designs and licenses the content and art direction for large LED surfaces, while cabinet supply and installation come from the display vendors behind each landmark. Brands planning a Seoul flagship screen with award-level content brief the studio for creative production and separately contract the hardware. Teams researching 3D LED display content standards will find d’strict’s portfolio the reference point for anamorphic perspective work in Korea.

• WAVE — anamorphic media art at COEX K-Pop Square (2018, approx. 1,620 m²)
• Ending Door — two approx. 33 m × 5 m media walls at Incheon Airport T2 (2018)
• VERSE.SEOUL and commissioned media-art work for commercial landmarks

Strengths: Award-documented portfolio (Red Dot) on Korea’s largest media facade; dedicated anamorphic content practice; brand-safe art direction for premium sites.

Limitations: Does not manufacture or resell cabinets — hardware must be sourced separately; engagement model is project-based content licensing rather than equipment sales.

Project-based content commissions, scoped per surface and campaign length.

Brands, landlords and agencies commissioning content for landmark LED surfaces in Gangnam, Myeongdong and airport media.

COEX K-Pop Square WAVE (2018); Incheon Airport T2 Ending Door (2018); VERSE.SEOUL at THE HYUNDAI SEOUL; installations documented on the studio’s site and Wikipedia.

Company Profile: Hi-Vision System, established in June 1998, works from a company building in Seocho 3-dong, Seocho-gu, and has spent more than two decades on the public-facing side of Korea’s display market: LED signboards for commercial clients and variable-message signage for traffic programs. Directory and trade listings record its LED display systems and sign products, and its client base includes Korea Expressway Corporation VMS programs — the roadside network whose cabinets face all-weather duty cycles most commercial signage never sees. That public-infrastructure experience is the differentiator for Seoul buyers: highway-duty cabinets carry stricter brightness, temperature and serviceability requirements than mall walls, and a vendor that lives in that world quotes realistic maintenance schedules. The company’s public profile is thinner than the listed players’ — revenue and headcount are not publicly documented — so due diligence runs through direct reference calls. Teams planning outdoor LED display programs exposed to monsoon-season rain can use the company’s highway record as the benchmark question set for any bidder.

• Commercial LED signboards for retail and corporate facades
• Variable-message signs (VMS) for traffic and ITS programs
• Public-information display systems for institutional clients

Strengths: Documented operation since 1998; Korea Expressway Corporation VMS track record; engineering tuned for all-weather public installations.

Limitations: SME scale with limited published financials; fine-pitch indoor work is not the company’s main focus.

Project quote, scoped per site and service program.

Traffic authorities, municipalities and commercial clients whose outdoor screens must survive Korean highway-grade weather duty.

Korea Expressway Corporation variable-message signage; Seoul-area commercial LED signage installations recorded in trade directories.

Company Profile: AVEC, founded in February 1996 and listed on KOSDAQ under code 066710, builds LED display boards (전광판) from Pyeongtaek in the Seoul metropolitan area, with about 226 staff and roughly KRW 62.6 billion in 2023 revenue per Korean corporate listings. Its stadium record is the reason the company appears here: screens at Jamsil Baseball Stadium, displays at Dongdaemun Design Plaza and Lotte World Tower, and KBO scoreboard programs across ballparks including Incheon’s SSG Landers Field. The business also spans AGV automation and city control solutions, which spreads risk across public-sector and industrial lines. For Seoul buyers, AVEC is the domestic answer when a scoreboard, perimeter or municipal display needs local engineering and multi-year service; the trade-offs are a scoreboard-centric portfolio rather than fine-pitch indoor walls, and a headquarters outside Seoul proper. Teams pricing a sports LED display program for a Korean venue should compare AVEC’s domestic service terms against factory-direct import pricing before signing.

• Stadium and baseball scoreboards — KBO-grade boards with timing integration
• Commercial and public LED display boards for municipalities
• City control and ITS display solutions alongside AGV automation lines

Strengths: KOSDAQ-listed with public filings; documented installs at Jamsil, DDP, Lotte World Tower and multiple KBO ballparks; export record to Indonesia, Vietnam and Taiwan.

Limitations: Portfolio centers on scoreboard-class boards rather than fine-pitch indoor walls; headquarters sits in Pyeongtaek, outside Seoul proper.

Project quote, typical of listed domestic manufacturers.

Venue operators, baseball clubs and municipal programs that need scoreboard-class boards with Korean-language engineering and long-term service.

Company Profile: ENT, founded in January 2012 and listed on KOSDAQ in December 2013 under code 065510, carved out Korea’s leading niche in financial information displays — the ticker and rate boards that run through banks and brokerages — with LED signage contributing 77.8% of fiscal 2023 revenue per Korean filing summaries. The product range goes beyond flat boards: the company documents spherical LED displays and a 400-degree-viewable signage format measuring 8.96 m, plus a SLIM LINE series for shallow mounting depth. In January 2025 Korean disclosures recorded an KRW 8.8 billion stake deal involving Vigor&Kaister, a reminder that the listed-company group structure keeps moving. For Seoul buyers, ENT is the specialist call when a financial-branch rollout or an unusual-geometry statement piece needs a vendor that has done both. The constraints: the Bundang base sits in Seongnam rather than Seoul proper, and the revenue concentration in financial signage means general outdoor advertising is a secondary line. Teams sourcing indoor LED display networks for branch rollouts can use ENT’s banking references as the local benchmark.

• Financial information displays — ticker and rate boards for banks and brokerages
• Spherical LED displays and 400°-viewable signage (8.96 m documented format)
• SLIM LINE series — shallow-depth LED for tight mounting envelopes

Strengths: KOSDAQ-listed with filing-backed revenue data; documented leadership in Korean financial information displays; unusual-geometry formats (spherical, 400°).

Limitations: Revenue concentrated in the financial-signage niche; based in Bundang, Seongnam, outside Seoul proper.

Project quote, scoped per network size and format.

Banks, brokerages and institutions rolling out information displays, plus brands chasing spherical or multi-view statement pieces.

Bank and brokerage information-display networks nationwide per Korean filings; SAMWHA E&C board supply recorded in Korean trade coverage.

Company Profile: Instruments Inc. works from Nonhyeon-ro in Gangnam-gu under the LIGHTWALL brand and occupies the closest-viewing end of Seoul’s LED market: its product pages document the LIGHTWALL MiniLED at P0.93, the Classic line at P1.5, the Stretch format at P2.9, plus Ribbon, Sculpture and Tile variants for non-flat geometry. The application list reads like Seoul’s premium interior economy — broadcast studios, aviation lounges, museums and galleries — where viewers stand a meter from the pixels and any seam or color shift shows immediately. Company scale and founding year are not publicly documented, which keeps due diligence reference-based; the product documentation itself is specific enough to hold vendors accountable on pitch, brightness and cabinet construction. For buyers, the decision logic is straightforward: at sub-1.5 mm pitches, compare LIGHTWALL’s Korean-priced offering against imported COB lines on seam visibility, calibration service and spare-module stocking. Teams pricing a LED display price guide reference for a studio build should quote both routes before committing.

• LIGHTWALL MiniLED P0.93 — close-view walls for broadcast and museum work
• LIGHTWALL Classic P1.5 — premium indoor fine pitch
• Stretch P2.9 plus Ribbon, Sculpture and Tile formats for custom geometry

Strengths: Documented P0.93 miniLED class product; format range covering flat to sculptural geometry; Gangnam base convenient for Seoul studio and gallery clients.

Limitations: Company scale and founding year not publicly documented; small-vendor capacity for very large multi-room rollouts should be verified.

Mid-premium, quoted per configuration.

Broadcast studios, aviation lounges, museums and galleries that need close-viewing fine pitch or sculptural LED formats.

Product documentation lists broadcast, aviation and museum installations in Korea; named client references are not publicly documented.

Company Profile: Unilumin Korea operates from Daeryung Post Tower on Gangseo-daero in Yeongdeungpo-gu as the Korean arm of Unilumin, the Shenzhen-listed manufacturer founded in 2004 (SZSE 300232). The Korean entity focuses on the product lines Korean buyers ask for most: the Upad family of all-in-one fine-pitch displays for meeting rooms, the Metavision and Upanel series for larger walls, and rental classes for events. Recruitment listings for public-sector LED sales signal where growth is aimed — Korean government and institutional procurement — and the brand showed at KOBA 2025 at COEX through distributor Brillcomm, keeping a visible booth rhythm in the Korean AV calendar. The subsidiary route is what separates this entry from brands that merely ship to Korea: a Korean entity can sign local service paperwork, hold stock and respond to site visits in Korean business hours. Evidence for the office address traces to recruitment postings rather than a heavily documented corporate page, so buyers should confirm current contact details directly. Teams comparing a rental LED display fleet supplier can weigh Unilumin Korea’s local-entity support against factory-direct pricing.

• Upad / Upad II / Upad IV all-in-one fine-pitch displays for meeting rooms
• Metavision and Upanel series for larger fixed walls
• Rental-class cabinets for Korean event programs

Strengths: Korean subsidiary entity in Yeongdeungpo-gu able to contract locally; parent with Shenzhen-listed scale and a full pitch menu; KOBA 2025 showroom presence.

Limitations: Korean office documentation is thinner than the parent’s global record; large-project lead times depend on Shenzhen production scheduling.

Mid-range, quoted per configuration.

Corporate meeting-room rollouts, public institutions and event companies that want an import brand with a local contracting entity.

KOBA 2025 exhibit at COEX via distributor Brillcomm; public-sector sales targeting per Korean recruitment listings; named Seoul references not publicly documented.

Company Profile: QSTECH, the Chinese LED manufacturer founded in 2008 with roots in Qingdao, is included here for the brightness end of the outdoor market: its product documentation covers outdoor cabinets rated to 10,000 nits, Q-PRO fine-pitch indoor lines and COB options, with control-system pairings across NovaStar and CalibreUK. Korea coverage runs through partner channels — Korean AV trade mentions cite Kyungmin Innotek, a company established in 2002, as a reported QSTECH partner — rather than a wholly-owned Seoul office, so this entry is best treated as a brand to invite to bid rather than a vendor to shortlist blindly. The practical test for buyers: request the current Korean partner’s name, service terms and reference sites in writing. Where outdoor programs face direct sun — rooftop billboards on Gangnam towers, riverside drives, stadium perimeters — the 10,000-nit class matters, and few import brands document it at this price point. Teams sourcing a COB LED screen alternative for indoor work can also cross-check QSTECH’s COB menu against factory-direct quotes.

• Outdoor cabinets rated to 10,000 nits — direct-sun billboard class
• Q-PRO fine-pitch indoor series for conference and control-room walls
• COB encapsulation options with NovaStar / CalibreUK control pairings

Strengths: Documented 10,000-nit outdoor brightness class; fine-pitch and COB breadth; established Chinese manufacturing scale since 2008.

Limitations: Korea presence runs through partner channels rather than an owned office — current partner identity and service terms should be verified in writing before award.

Mid-range, quoted per configuration.

Outdoor media owners and stadium programs that need maximum brightness per won, with a verified local service partner.

Global outdoor and stadium references documented on qstech.net; Korea-specific named sites are not publicly documented.

Company Profile: MK Display, working from the Chunui Technopia complex on Gwangnaru-ro in Guro-gu since 2002 (incorporated 2007), represents the Guro-gu SME cluster that still manufactures display boards inside Seoul’s western industrial belt. The company documents indoor and outdoor full-color LED boards, small pixel-pitch lines, LCD video walls and kiosks, and lists its own LED factory operation spanning Namyangju and a China facility — a hybrid that keeps Korean assembly and service close while sourcing panels at import economics. A registered Korean trademark (KIPO 4020200145926) and a 24-hour nationwide after-sales commitment round out the profile. For buyers, MK Display is the local-factory option when a project needs fast site visits, Korean-language contracts and A/S response measured in hours rather than international logistics cycles. The trade-offs are SME scale and export-program experience that is thinner than the listed players’. Teams specifying a shopping mall LED display for a Korean retail group can use MK’s 24-hour service terms as the benchmark for local support clauses.

• Indoor and outdoor full-color LED boards for retail and institutions
• Small pixel-pitch LED lines for close-view commercial walls
• LCD video walls and interactive kiosks as companion products

Strengths: Seoul-based with its own factory footprint (Namyangju + China); 24-hour nationwide A/S commitment; registered Korean trademark.

Limitations: SME scale with limited published financials; export documentation experience thinner than listed manufacturers.

SME pricing, quoted per project.

Korean retailers, schools and public institutions that prioritize local factory support and rapid after-sales response.

Retail and public-institution signage programs per mkdisplay.kr; named client references are not publicly documented.

Company Profile: The Lower Code operates from Seongsui-ro in Seongdong-gu — Seongsu-dong, the converted warehouse district that now hosts much of Seoul’s event production economy — and rents LED video walls by the day across indoor and outdoor classes from P2.5 to P10. The catalogue covers LED columns and pillars, branded screen packages and media-server integration, and the company serves clients nationwide with Seoul, Busan, Incheon and Jeju coverage. What makes this entry useful for buyers is pricing transparency: the company publishes its own Seoul LED price guide, quoting around KRW 50,000–80,000 per square meter per day for indoor P2.6 panels — a rare public number in a market where most rental quotes arrive only after briefs. Treat the figures as vendor-published ranges that shift with season and availability, and compare at least three quotes on identical panel schedules. As an emerging operator, founding year and corporate scale are not publicly documented, so reference checks matter. Event teams mapping a LED display rental price guide against vendor quotes will find the published rate card a useful baseline.

• Indoor/outdoor LED wall rental — P2.5 to P10 classes by the day
• LED columns, pillars and branded screen packages for brand activations
• Media-server integration and on-site operation crews

Strengths: Published Seoul price guide (P2.6 indoor around KRW 50,000–80,000/m²/day, vendor-published); shape variety beyond flat walls; nationwide coverage incl. Busan, Incheon, Jeju.

Limitations: Emerging operator with founding year and scale not publicly documented; peak-season inventory availability should be confirmed early.

KRW 50,000–80,000/m²/day for indoor P2.6 (vendor-published, indicative); final quotes per event schedule.

Brand activations, pop-ups and corporate events in Seongsu and central Seoul that need transparent day rates and custom form factors.

Event rental programs across Seoul, Busan, Incheon and Jeju documented on thelowercode.com; named client references are not publicly documented.

Company Profile: VSO Korea appears in Seoul event-production listings as a Gangnam-gu rental contact for LED screens in the P2.6 and P3.9 classes, with a service list that leans into geometry: concave and convex builds, circle and C-shape screens, cube structures, floor LED and LED dance floors, plus holographic fan units for premium accent effects. That shape library is the reason it closes this list — fan events and K-pop adjacent activations in Seoul increasingly ask for non-flat stage surfaces, and few small operators document shape options explicitly. The caveats are equally clear and we state them plainly: public evidence for this company is thin, with a single strong listing appearance, no verifiable corporate registry data captured at research time, and no named projects on record — founding year, staff count and client list are not publicly documented. Treat this as an entry to contact and verify, not a pre-vetted vendor: confirm business registration, insurance and current inventory before contracting. Teams sourcing a concert LED display package can use the shape checklist below as briefing material with any rental house.

• P2.6 / P3.9 LED screen rental in flat and custom shapes
• Concave, convex, circle, C-shape and cube screen builds
• Floor LED, LED dance floors and holographic fan accents

Strengths: Documented custom-shape focus (concave/convex, circle, cube, floor LED); Gangnam base in Seoul’s event economy; dance-floor and holographic fan add-ons.

Limitations: Thin public record — registration, insurance, scale and references must be verified directly before contracting.

Event-day quotes per shape, panel count and crew schedule.

Fan meetings, brand pop-ups and stage shows that need shaped LED surfaces rather than flat walls, after direct verification.

Not publicly documented.
