DVLED Principles and Technology
Traditional LED Screens vs. DVLED
Light Emitting Diodes (LEDs) are an old technology repurposed recently to create text and images on screens. The once leading-edge display technologies like liquid-crystal display (LCD) or Organic LED (OLED) and the many offshoots are about to be eclipsed by Direct View LEDs (DVLED). The older screen technologies use filters and backlights.
The base of DVLED innovation starts with LED arrays of micro-pixels that emit color and light directly. Expect increased brightness, perfect blacks, and a wide color range. DVLED screens are more immersive and life-like.
"Sub-pixels" of red, green, and blue LEDs are in each pixel. This strategic arrangement allows DVLEDs to create any color on the visual spectrum that humans can see. Turning off a pixel creates a perfect black. High resolution depends on "pixel pitch," which is simply the distance, or frame, between each pixel. DVLEDs have astonishingly detailed images due to the minimal distance between pixels.
Complex circuitry modulates the individual compound LEDs for exacting control of color and brightness. Direct View LED walls are so packed with pixels that "bezels" (or borders) become virtually eliminated. Older large LCD or OLED walls have noticeable bezels around every panel. DVLED technology has panels that can fit together to integrate images.
The advantages of DVLEDs include increased contrast and brightness, so much so that they work well in sunlight. Compared to older screen rendering technologies, DVLEDs have a more fantastic color range (color gamut). Because the bezels fade out, for all practical purposes, screens can scale up to any desired size and are only limited by engineering and construction capabilities. Durability is another outstanding DVLED technology; screens can last up to 100,000 hours.
Many characteristics differentiate DVLED from older LED screens. With fine pixel pitch and seamlessness, DVLED screens have dramatically improved resolution, especially for large Direct View LED walls. A recent variant, MicroLED, has ultra-fine pitch and some potential for seamless integration of panels, but the technology is still under development. And there are manufacturing hurdles ahead. OLED has improved with blacker blacks, but borders are noticeable between panels.
Brightness and contrast significantly improve with DVLED over traditional LED technologies. Turning off pixels creates pitch-black areas on the screen. While other LED designs have exceptional brightness and contrast, DVLED outpaces conventional LEDs and works in well-lighted settings. OLED is marginally more energy efficient but does not do well in the light. Manufacturing costs are higher with both MicroLED and OLEDs. On a larger scale, OLEDs are often more expensive.
Advanced image processing and calibration in DVLED screens, including massive LED walls, produce whole screen uniformity. Other LED designs have struggled with noticeable panel borders that DVLED technologies have virtually eliminated. The result is an entirely uninterrupted viewing surface that lends itself to uses in all applications.
Direct View LED walls make outdoor digital signage excel. Large displays are visible at a great distance day and night at car dealerships, airports, storefronts, malls, and more. Adding to the quality of digital signage of a DVLED screen is visibility and clarity at wide viewing angles. Businesses and organizations in public spaces can build DVLEDs into walls of almost any shape and size.
Broadcast and film content can realize high-resolution, clear, and realistic backgrounds. Historically, studio backdrops were awkward and often hand painted. Today, DVLEDs create virtual backdrops for newsrooms, television, and film productions. The technology creates a "High Dynamic Range" for near real-life detail, brightness, and color range, thus rendering excellent still or video images.
Complex system control rooms benefit from large DVLED monitors. The refined pixel pitch design allows technicians to view multiple information feeds. The high-resolution data is available for adjustments and actions. The technology's inherent durability of DVLEDs adds value to 24/7 control rooms. In corporate environments, this technology communicates and engages personnel. DVLED design's scalability means conference rooms, lobbies, and audience rooms are visually stunning and augment the speaker's perspectives. Entertainment venues come alive with super-scale Direct View LED walls.
Affordable and accessible, DVLED technology offers the future a level of innovation that traditional LED design cannot match. From art installations to home environments and retail spaces, DVLEDs will enhance daily living.
Immersive visual experiences will advance in education, signage, entertainment, art, and virtual productions. DVLED is continuing development with an already well-developed technology. Improvements in pixel pitch will produce real-world images that are difficult to distinguish from reality. Human spaces will redefine experiences and interactions. Ceilings and walls, including curved surfaces, will transform into dynamic, real-life life, and engaging displays.
Virtual meetings will replace in-person meetings, and participants can be anywhere worldwide. Creative digital designers are developing ways to place individuals within a virtual room where everyone can communicate. In other words, augmented reality without goggles will become the rule.
Democracy will get a boost as large-scale DVLEDs evolve from premium technology to a commonplace, affordable product. Large displays in the home will make virtual visits with friends and family common. People will immerse in conversations on a one-to-one ratio, where people and objects appear in exact proportion as in real life. Soon to become obsolete are traditional projectors, in-person movie screens, traditional LED screens, and more.
Marketing paradigms are shifting in how marketers use advertising in public spaces. In combination with Artificial Intelligence (AI), DVLED screens, large and small, will be interactive and sensitive to context. Customers can ask questions and then get answers in real-time. Virtual actors will appear full-size, have human mannerisms, make eye contact, and have lip movements that will sync with their speech.
All technologies will plateau at some point, and Direct View LED walls are no different. Railroads have remained the same in one hundred years. They just got faster. Screens have never been so near real life, and improvements will slow in the following decades. Improving screens is only a matter of perfecting DVLED's inherently superior flat-screen design. From small screens to huge wall installations, DVLED technology will dominate the market.
