Luxwave Delivers 2 BOE COB P0.9 Projects in Q1/2026

Which BOE COB P0.9 Projects Did Luxwave Deliver in Q1/2026?

Q1 2026 marks Luxwave's first year deploying BOE's flagship COB MicroLED line in Vietnam, with two completed and delivered projects. The first project is the reception hall at Thanh Thang Castle in Ninh Binh, covering 6.5m², delivered in April. The second project is the training room at Optupus International Library in Hanoi, covering 8.4m², delivered in May. Both utilize the BOE BYH012 COB P0.9 cabinet — the smallest pixel pitch currently available in Luxwave's distribution portfolio, according to the BOE BYH-COB Series Datasheet 2025.

While the total deployment area of 14.9m² is not large, these are two milestone projects: Luxwave's first practical deployment of the BOE BYH-COB P0.9 line in Vietnam, in two entirely different contexts — a luxury private residence and a technology training space. Both chose COB P0.9 for the same core reason: viewers are seated close by, requiring the highest image quality and aesthetic appeal.

Why Did Both Installations Choose the BOE BYH012 COB P0.9 Configuration?

Both projects used the same standardized high-end combo configured by Luxwave: the BOE BYH012 COB cabinet paired with the Novastar U20 Pro processor. The 600×337.5mm COB cabinets allow for seamless integration, with inter-module seam gaps under 0.1mm, making them indistinguishable to the eye at a distance of 2m. This is a critical factor for luxurious spaces where visible seams can disrupt the monolithic feel. The P0.9 pitch and the flat surface of COB are mandatory choices when viewers are in close proximity to the screen.

The reasons for choosing COB over SMD lie in three operational aspects. Firstly, COB technology mounts chips directly onto the PCB and covers them with a protective resin layer, creating a seamless flat surface without protruding LED beads that are prone to damage and glare at close viewing distances. Secondly, the passive, fanless cooling design ensures near-silent operation — crucial for quiet reception halls and training rooms. Thirdly, high contrast and chip durability help maintain stable performance throughout the 100,000-hour lifespan specified in the datasheet.

The Novastar U20 Pro processor was selected for its ability to upscale high-resolution sources, synchronize colors across cabinets, and support multi-windowing — essential for the Optupus training room, which needed to display content from laptops, cameras, and playback devices simultaneously. Luxwave's technical team, holding Novastar NCE Professional certifications, can calibrate uniformity and color gamut on-site, rather than relying on factory default settings.

How Was Thanh Thang Castle Implemented and What Were the Challenges?

Thanh Thang Castle is a large-scale private residence in Ninh Binh, featuring a reception hall decorated with crystal chandeliers and carved wood structures in a European style. The challenge for Luxwave was clear: the 6.5m² LED screen needed to blend seamlessly with the wooden background when off — appearing almost invisible — and display high-resolution content vividly when on, all within a space with significant light reflections. This requirement could only be met by COB P0.9 with its full-face black coating and 100,000:1 contrast ratio, as its dark, flat surface merged with the dark wood.

The primary installation challenge was the mounting structure. Carved wood is not a flat metal surface that can be easily adjusted, whereas the 600×337.5mm COB modules require a flatness tolerance of only ±2mm — exceeding this threshold would create shadows and color shifts at the seams. The technical team conducted meticulous measurements and fabricated auxiliary frames to achieve the required flatness, while also protecting the valuable wood from scratches or damage during the process. The entire installation and calibration took 5 days, longer than the other project due to the complexity of the substrate structure.

The results after acceptance met the investor's expectations. Under the crystal chandelier's light, the BYH012's brightness was sufficient to combat glare without causing discomfort when lights were dimmed, and the black coating made the screen virtually disappear against the wooden backdrop. When displaying content, the images were sharp even at a 2m distance — the typical viewing proximity for guests in the hall. This demonstrates why ultra-fine pitch is used in luxury private spaces: not for distant viewing, but to withstand close-up scrutiny.

What Were the Distinct Technical Requirements for Optupus International Library?

Optupus International Library in Hanoi is a technology training facility where the 8.4m² LED screen serves as the primary display for students. Unlike a private residence, this is a continuously operating environment with more practical demands: content must be clearly visible to students seated at distances ranging from 2 to 4m, effectively display small text slides and data tables, and perform well under classroom lighting conditions with overhead downlights. The context of MLED technology training also requires the screen itself to be a reliable reference product in terms of quality.

The core technical requirement was brightness and uniformity. With ambient light levels in the room around 450 lux from the ceiling panels, the BYH012's brightness is sufficient to counteract glare in standard mode without needing to reach peak levels that could reduce chip lifespan. The technical team calibrated uniformity to ensure consistent brightness across modules, preventing the "patchy" effect easily noticeable by students viewing white slides. The P0.9 pitch ensures that viewers in the front row at 2m cannot discern individual pixels — an experience comparable to a high-quality LCD screen but at a much larger scale.

Thanks to the screen being mounted on a flat wall, the installation process was significantly faster than at Thanh Thang Castle: framework erection, module assembly, and calibration were completed in 3 days, becoming operational on the fourth day after delivery. The flatness of the substrate was a direct factor in shortening the timeline — a lesson Luxwave consistently emphasizes during site surveys: the complexity of the mounting surface impacts the schedule more than the screen area. Optupus also serves as a good reference for clients interested in applications for showrooms and exhibitions requiring large, seamless displays.

What Lessons Were Learned from These Two Projects for Clients and the Installation Team?

These two Q1/2026 projects highlight that COB P0.9 is not a default choice for every space but a conditional decision. Both Thanh Thang Castle and Optupus met three criteria justifying the ultra-fine pitch: viewers seated close (under 3m), requirements for high aesthetics or clarity, and environments with strong reflective light demanding good brightness and contrast. Conversely, if the furthest seats are over 5m away, P1.5-P2.5 would be sufficiently sharp and significantly more cost-effective. Choosing the correct pitch based on actual viewing distance is more important than selecting the smallest pitch — this is a principle Luxwave consistently advises on.

The second major lesson regarding project execution concerns lead time and mounting structures. COB cabinets are manufactured to order, taking 14-21 days at BOE, rather than being stocked. Therefore, all launch plans must factor in an additional 21-30 days from the contract signing date. The substrate structure also dictates the installation schedule more than the screen area: a flat wall allows for 3 days, while carved wood requires 5 days. The on-site survey — measuring surface flatness within ±2mm tolerance, assessing ambient light levels, and determining the mounting method — must be completed before providing an accurate quote; remote estimations are not feasible.

Following these two projects, Luxwave has placed a pre-order for a batch of BOE BYH P1.2 COB in late Q2/2026 to anticipate demand for executive meeting rooms, as BOE announced a 10-15% price reduction for COB at ISLE 2026. The strategic focus for 2026 is 5-8 COB projects, prioritizing two segments: premium 20-40m² meeting rooms and high-end private reception halls.
