Church LED Display — TQW Series Micro COB LED Church Redefining Immersive Worship Visuals in Large Sanctuaries
Church LED Video Wall Upgrade at Seoul International Christian Center Main Sanctuary (1,800 seats, 2025)
Church LED Display technology is transforming modern worship experiences worldwide. Leye Display’s TQW Series Micro COB LED Church solution delivered a high-resolution, seamless Church LED Video Wall for the main sanctuary at Seoul International Christian Center, enabling clear scripture, hymns, and sermons even in natural daylight. This case study details the full transition from traditional projectors to Micro COB LED Church displays and the resulting benefits.
Project Background & Upgrade Needs
The original setup used 4 high-lumen projectors + 120″ motorized screen, but faced long-term pain points
- Severe washout from side windows during morning services, making subtitles hard to read
- Low contrast under stage lighting, losing details in videos (hymn MVs, sermon illustrations, scripture animations)
- Frequent lamp replacements every 8–12 months, high maintenance costs, and downtime disrupting worship continuity
- Blurry livestream text, especially small fonts, reducing remote engagement
Desire for richer dynamic content: multi-layer ProPresenter overlays, real-time subtitle translation, baptism video replays
Quantified Project Challenges
| Â Challenge Category | Â Specific Issue | Impact on Worship | Â Quantified Metrics (Original System) |
|---|---|---|---|
| Â Ambient Light Interference | Direct morning sunlight + 4000K stage cool light | Â Screen washout, unreadable subtitles | Â Effective contrast < 300:1 |
| Â Insufficient Clarity | Â Limited projector resolution + diffuse reflection | Â Back rows & online viewers can’t see scripture clearly | Â 24pt text blurry beyond 5m |
|  Maintenance & Stability |  Short bulb life + dust buildup |  At least 1 monthly maintenance window | Annual maintenance cost ≈ KRW 60,000,000 |
|  Energy Consumption & Cost |  High-power projectors + AC compensation |  High monthly electricity bills |  Peak power ≈ 8–10 kW |
| Â Future Scalability | No HDR/high-refresh dynamic content support | Â Limits creative sermons & immersive hymns | Â No HDR, no high frame rate support |

Frequently Asked Questions
The TQW Series Micro COB LED Church utilizes flip-chip Micro COB technology, delivering outstanding ambient light resistance for Church LED Display applications (600 nits brightness + low-reflect coating). It remains clear and high-contrast (5000:1) even under direct morning sunlight — no curtains needed — ensuring a pristine Church LED Video Wall experience throughout the day. With a >100,000-hour lifespan and near-zero maintenance, it consumes only 1/2–1/3 the power of equivalent projectors, significantly reducing church operating costs. Full HDR10 support brings more vivid, emotionally engaging visuals to hymns, scriptures, and sermon videos, elevating the overall Church LED Display immersion in worship.
No. With a 1.2mm pixel pitch and Micro COB precise encapsulation plus factory full-range uniformity calibration, the TQW P1.2 appears virtually pixel-free from 5 meters and beyond, delivering near print-like fineness — ideal for front, middle, rear rows in medium-to-large sanctuaries and for livestream viewers.
Installation is scheduled for nights and weekends, completed in just 11 days without interrupting any worship service. The TQW Series features full front-service design — single module replacement takes only 10–30 seconds via hot-swap, resulting in near-zero downtime. Even rare future issues can be resolved quickly between services without affecting the congregation.
For the 81m² main screen at Seoul International Christian Center, the TQW system averages 3.2–4 kW consumption vs. 8–10 kW peak for the old projectors, delivering ~35–40% monthly electricity savings (approximately KRW 4,000,000–5,000,000 depending on local rates). Lamp/filter replacements are virtually eliminated, making the total cost of ownership (TCO) superior to projectors within 3–4 years.
Fully supported. The TQW Series is compatible with the latest ProPresenter 7/8 via high-performance Novastar sender cards for seamless integration. During the project, we collaborated with the church media team to optimize real-time Korean-English subtitle overlays and multi-layer content templates, ensuring smooth transitions for sermons, hymns, and announcements.
Very convenient. The TQW Series uses standardized modular design (same physical cabinet size compatible with P0.9–P1.8 pitches), so future upgrades only require replacing modules — no structural or cabling changes needed. Side-screen expansion can reuse the existing control system and power architecture, maximizing protection of your initial investment.
