Introducción
Did you know? In fact, pantallas LED have their own place in the virtual field. Many movies are shot using LED displays and XR virtual effects. Then, some people may wonder: How can the XR effect be achieved with an LED display? Don’t worry; this article will tell you how to do it.
1. XR technology foundation and LED display characteristics
1). XR technology foundation
XR technology, this “all-round player” that combines augmented reality, virtual reality and mixed reality, is gradually changing the way we perceive the world. It blurs the boundary between virtual and reality, making us feel like we are in a wonderful world that is both real and illusory.
1.1). The core principle is revealed:
- Object position tracking and positioning technology:
This technology is like installing a “locator” on every object in the real world. Whether through cameras, sensors or specific tracking devices, the system can capture the position information of objects in real-time to ensure that virtual elements are accurately aligned with the real world.
In this way, when you wear an XR device, virtual objects can interact with you as if they really exist.
- Real-time graphics rendering engine:
This engine is like a super “painter”. It instantly draws ultra-realistic virtual scenes according to the angle of your eyes and head. Whether it is the delicate light and shadow effects or the realistic object texture, it can make you feel as if you are in the real world.
1.2). Unique advantages of XR technology:
- Virtual and real integration, seamless connection:
XR technology makes the transition between virtual and reality natural and smooth, and it is difficult for you to tell which is real and which is virtual. This new way of experience makes you feel like you have travelled to a world that is both familiar and unfamiliar.
- Human-computer interaction, natural and convenient:
Compared with traditional input devices, XR technology allows you to interact directly with virtual elements. Whether through gestures, voice or eyes, you can easily communicate with the virtual world, making the interaction more natural and convenient.
2). LED display characteristics
LED display, the “light and shadow magician” composed of countless small lamp beads, is attracting more and more attention with its unique charm.
LED display is actually made up of a bunch of small lamp beads that can emit red, green and blue light. Under the control of the electronic drive circuit, these lamp beads can be flexibly turned on and off and adjust the brightness to display various colors and patterns. It is like a small “light spot painter” drawing a colourful picture together.
2.1). Four major technical features of LED display screens:
- Alto brillo, dazzling:
The brightness of the LED display screen is very high, and it can be clearly displayed even in a strong light environment. Whether it is an outdoor billboard or an indoor stage background, you can notice it at a glance.
- High contrast, clear layers:
The contrast of the LED display screen is also very high, with clear black and white and bright colours. This makes the picture more three-dimensional and layered so that you can touch every detail.
- Good colour reproduction, lifelike:
The LED display screen can accurately restore various colours and display more realistic pictures. Whether it is natural scenery or portraits, you can feel the shocking effect as if you are on the scene.
- Fast frecuencia de actualización, smooth and free:
The refresh rate of the LED display screen is very fast, which can display smooth dynamic pictures. Whether it is a fast-moving object or an unpredictable scene, you can feel the silky visual enjoyment.
2. Application scenarios of LED display screens in achieving XR effects
1). Film and television production:
In film and television production, LED display screens are like a “magic cloth” that can be transformed into the scene you want at any time. Whether it is a bustling urban street, a quiet rural field or a mysterious future world, it can be easily achieved through LED display screens.
This not only greatly improves the flexibility and efficiency of shooting but also allows directors to be more creative and create more realistic virtual backgrounds.
For example, the short film “Only to Meet You in Dreams” fully utilizes the advantages of LED display screens to create a virtual world full of fantasy. The perfect fusion of virtual backgrounds and real actors presented by LED display screens makes the audience feel as if they are in a dream that is both real and illusory.
This new viewing experience not only makes the audience excited but also opens up new possibilities for film and television production.
2). Advertising:
In advertising, LED display screens have become the first choice for many businesses due to their high brightness, wide viewing angle and dynamic display. Whether it is outdoor billboards, shopping mall windows or bulletin boards in subway stations, you can see LED display screens.
Combined with XR technology, LED display screens can display more vivid and realistic advertising content. Through gesture recognition, touch screen or voice recognition, the audience can interact with the advertisement and experience unprecedented fun and participation.
This new advertising method not only improves the attractiveness and interactivity of the advertisement but also brings more business opportunities and potential customers to merchants.
3. Key technologies for LED display screens to achieve XR effects
1). Object position tracking and positioning technology
Object position tracking and positioning technology are like a “navigator” in the XR world. It allows the XR system to know where the user or object is in real-time and then align this position with the virtual world.
In this way, when you walk into the virtual scene, everything will feel so real, as if you are really there.
1.1). Technical analysis:
- Mosys camera tracking system:
Imagine that you are surrounded by “smart eyes” – that is the Mosys camera. They stare at the small marks on your body, just like staring at the stars, and calculate your position through algorithms. This technology is very stable and suitable for various complex shooting scenes.
- Black Trax dynamic tracking system:
Black Trax is like an infrared “detective”. It emits infrared rays and then captures the “little secret of infrared reflection” on your body so that it knows where you are. This technology is very flexible, and it doesn’t matter if you move around; it can catch up with you.
2). Real-time graphics rendering engine
The real-time graphics rendering engine is the “painter” of XR. It draws everything you see in the virtual world, such as models, textures, light and shadow, in real time and sends it to the LED display. In this way, you can see the virtual scene that is integrated with the real world.
Different rendering engines are like different painters, with different painting styles and speeds. For example, Unreal Engine draws very finely and has many functions, which are suitable for making blockbusters or games, while Unity draws very quickly and is very easy to use, which is suitable for quickly making a small XR application.
3). High-speed and low-latency network support
High-speed and low-latency networks are like the “express delivery boy” of XR. XR needs to transmit a lot of data and pictures. If the network is slow or stuck, the XR effect will be greatly reduced. Therefore, XR can only be played well if there is a fast and non-delaying network.
The arrival of 5G network is like installing a “turbocharger” for XR. It has high speed, low latency, and can connect to many devices. It is simply tailor-made for XR. With 5G, XR can be played more smoothly and realistically, and can be used in more places.
4. Creative practice of realizing XR effects with LED display
1). Customized content creation
Customized content is like “clothes” tailored for XR. You need to design appropriate virtual backgrounds and special effects according to the scene and purpose. For example, when making a movie, you need to design a cool virtual world according to the script and scene.
When doing entertainment performances, you need to design a stage that makes people’s eyes shine according to the program and the audience’s preferences.
360-degree video and interactive experience are like the “magic wand” of XR. The 360-degree video makes you feel that you are really in the virtual world; the interactive experience allows you to interact with the virtual world, which feels more real and more interesting.
2). Interactive element design
Designing interactive elements is like adding a “remote control” to XR. Through gesture recognition and touchscreen technologies, you can interact with the virtual world more naturally.
For example, when shopping, you can choose products by waving your hand; when playing games, you can control the character by touching the screen.
Gesture recognition and touch screens are like the “sensors” of XR. Gesture recognition allows you to communicate with the virtual world with gestures; the touch screen allows you to control things in the virtual world with your fingers. These technologies make XR more fun and interesting.
3). Combination of spatial layout and sound and light effects
Spatial layout and sound and light effects are like the “stage design” of XR. You need to place the LED display in the most conspicuous place, and then arrange the space and lighting reasonably to create a realistic virtual scene atmosphere.
For example, when making a movie, you need to design the lighting and space according to the script and scene; when doing entertainment performances, you need to use lighting and sound to create a shocking stage effect.
The combination of sound and light effects and LED screen content is like the “seasoning” of XR. Through precise audio positioning and lighting design, you can make the virtual scene more realistic and more atmospheric.
For example, when playing games, sound and light can make you feel more immersive; when making a movie, sound and light effects can also make the scene more real and touching.
5. Challenges and solutions for achieving XR effects with LED displays
1). Desafíos técnicos
LED displays are like an “all-round player” for XR, but it is not easy to achieve the best. Resolution, refresh rate, and latency are all problems. With a higher resolution, the picture is finer, but the hardware and processing pressure are also greater.
With a higher refresh rate, the picture is smoother, but data transmission and processing are also difficult; with lower latency, XR is more realistic, but the technical difficulty is also higher.
- Solution discussion:
But don’t worry, technology is always improving. We can use new technologies such as Micro-LED to improve resolution and refresh rate; optimize data transmission and processing algorithms to reduce latency.
Use advanced sensors and tracking technologies to improve tracking accuracy. In this way, LED displays can better achieve XR effects.
2). Problemas de costos
Although XR technology is fun, it is not cheap. Hardware, software development, and operation all cost money. High-quality LED displays, tracking systems, and rendering engines are not cheap; software development and maintenance also require manpower and material resources; operation and promotion also cost money.
- Solution discussion:
But don’t worry, we also have ways to reduce costs. More efficient hardware design and manufacturing processes can be used to reduce hardware costs; software resources can be shared and reused to reduce software development costs; innovative business models and marketing strategies can reduce operating costs. In this way, more people can play XR.
