Pro-AV and Large Venue DMDs

Introduction to the Pro-AV (Professional Audiovisual) Sector

Pro-AV stands for Professional Audiovisual. Distinct from consumer-grade audiovisual products, Pro-AV is a professional application sector that provides customized audiovisual integration solutions for commercial and public environments. It covers a broad spectrum of application scenarios, including conferences and exhibitions, cultural tourism performances, command and control centers, education and training, and public address systems. Unlike consumer-grade audiovisual products, Pro-AV systems impose extremely high requirements on system stability, output image quality, audio fidelity, and multi-device compatibility. Key technical requirements to be addressed by Pro-AV solutions include: ensuring fault-free continuous operation over extended periods; supporting signal input and output across multiple resolutions; completing color uniformity calibration for extra-large display screens; and delivering reliable sound field coverage for audiences of up to thousands of people. Pro-AV is not merely an individual hardware product, but an integrated system composed of display terminals, processing chips, transmission equipment, control terminals, and acoustic systems. The performance of the core chip directly determines the output quality and maximum implementation capability of the entire Pro-AV solution.

To meet the specific application requirements of large venues, DMD chips are equipped with specialized designs and targeted performance advantages: First, large venues mostly adopt tiled projection to achieve extra-large-scale display. DMD chips deliver higher pixel stability, making it easier to calibrate the consistency of color and brightness between different projection units. They will not cause problems such as pixel shift and uneven color attenuation after long-term use, and can support the output of seamless extra-large images ranging from hundreds to thousands of inches, satisfying the demand for large-scale images in opening and closing ceremonies of sports venues, large-scale cultural performances, and themed exhibitions at convention and exhibition centers. Second, large venues require equipment to maintain long-term continuous operation. DMD chips work based on the principle of reflective imaging, so the chip itself generates less heat and enjoys stronger structural stability, which can withstand more than ten hours of continuous operation per day, with a failure rate far lower than other imaging solutions, fitting the requirements of high event density and low operational maintenance for large venues. Furthermore, current high-end DMD chips targeting large venues generally support native 4K or even 8K resolution. Combined with high-frame-rate driving capability, they can output clear images with a 120Hz high refresh rate. When broadcasting sports events in sports venues, they can clearly present high-speed moving competition pictures, avoid trailing and blurring, and improve the viewing experience. At the same time, DMD chips have a wider color gamut coverage, and can restore colors that meet professional radio and television standards, fitting the requirements of picture color atmosphere for cultural tourism performances.

In addition to projection imaging, large-scale laser display screens in large venues also generally use DMD chips as the core imaging component. Compared with direct-view LED screens, the tiled display solution based on DMD chips has lower cost per unit area, and can achieve seamless splicing at the same time, which avoids the pixel gap problem of direct-view screens and brings a stronger integrated viewing experience of the overall picture. It is highly suitable for the demand of large venues for ultra-high-definition, large-size, low-cost display solutions.
