High-Quality Projector 4k 120hz Factory & Factories

Pioneering Next-Generation Ultra-HD Optical Solutions, Advanced 120Hz Display Technology, and Enterprise ODM/OEM Integrated Global Manufacturing Services.

Understanding the Engineering Behind 4K 120Hz Projection

High-performance optoelectronic architectures designed to meet the demands of modern ultra-low latency, high refresh-rate interactive displays.

Optical Architecture

Why High Refresh Rates Demand Advanced Optomechanical Design

To project a true 4K UHD image (8.3 million distinct pixels) at a high frame rate of 120Hz, the core light engine and digital micro-mirror device (DMD) controller must process data speeds exceeding 48 Gbps. Our manufacturing process integrates specialized liquid-cooled cooling systems, high-bandwidth chipsets, and optical components to combat the extreme thermal loads generated by high-intensity light sources operating at elevated refresh rates.

DMD Dynamic Shift Tech

Utilizes ultra-high-speed pixel shifting technology with sub-millisecond optical actuators. This ensures native-equivalent 4K crispness while maintaining a fluid 120Hz screen refresh cycle, eliminating visual judder and screen tearing in dynamic visual applications.

MEMC Motion Control

Integrated hardware-level Motion Estimation, Motion Compensation (MEMC) co-processors interpolate frames with low latency. Ideal for high-frame-rate console gaming, live sport simulations, and real-time visualization applications.

HDMI 2.1 Interface & eARC

Supports uncompressed video transmission, VRR (Variable Refresh Rate), and ALLM (Auto Low Latency Mode). Provides seamless connectivity with current gen gaming consoles and high-output enterprise media servers.

Our Manufacturing Facilities & Integrated Workshops

Take an inside look at how our precision optics, durable structural molds, and electronics undergo strict fabrication and validation protocols.

Precision Molds

Mold Injection Department

The mold and injection molding workshop is located next to our factory, equipped with sophisticated digital machines above conventional market standards to ensure a good foundation for each product. By controlling structural mold precision within micrometric margins, we ensure light engine alignment is maintained under thermal expansions, protecting the optical path integrity of 4K 120Hz units.

Assembly & Production

Assembly Line Operations

Covering an area of 4000 square meters, the factory is equipped with production, injection molding, assembly, and testing workshops with large volume. After the recent large-scale adjustment and screening, there are about more than 100 qualified assembly workers which are reasonably distributed in different departments and all with good professional & ethical quality.

Modern workshop for production and assembly, we introduce the most advanced manufacturing equipment, CNC machines, high-end test instruments. In order to meet our clients' different requirements, we set the workshops based on 5S standard dust-free available for every unit of product, our monthly production and assembly capacity is up to 50000 units!

Quality Assurance

Testing Department & Optics Labs

In order to ensure the performance of each machine, it is more possible to control the after-sale defect rate for customers, we have equipped two groups of test rooms, a total of 12 test rooms, by professional and senior quality inspectors to test the incoming material, the first inspection after finishing assembly, and sample inspection before shipment. High refresh-rate parameters, latency limits, and color temperature uniformity are strictly validated here.

Aging Test

Aging Test Department

The aging test room is next to the functional test room in order to improve work efficiency and reduce work errors, and can allow at least 200 machines for aging test at the same time. Each unit runs continuously for hours under full workload cycles to identify component wear-out and prevent early thermal failures.

The Shenzhen-Dongguan Synergy

Operating a corporate headquarters in Shenzhen (Nanshan-Baoan corridor) and a dedicated production base in Fenggang, Dongguan allows our team to transition from design prototypes to mass mold injection within days. The proximity limits assembly lag and streamlines raw material supply chains for high-bandwidth PCBs, optical engine modules, and custom LED/DLP optical matrices.

Speedy Global Port Connections

Located just 40 minutes from the Hong Kong Port and 30 minutes from the Shenzhen Yantian Port, we guarantee low-latency logistical handoffs. This ensures that cargo moving by sea, land, or express air reaches distributors, online fulfillment nodes, and commercial enterprise clients on schedule, backed by comprehensive tracking systems.

Sourcing Security & Cost Stability

Our supply chain ecosystem features long-term raw material reserve strategies and direct partnerships with major chipset and optoelectronic semiconductor fabs. This insulates our OEM clients from raw material price spikes, ensuring long-term pricing contracts remain steady.
