1. Brief introduction to direct-view LED display
Direct-view LED display, in simple terms, is the kind of large screen that we usually see in the streets, ショッピングモール, cinemas, and even in the living room at home, which is a large screen with a large number of small LED lamp beads densely arranged.
Don’t underestimate these lamp beads; they can emit light directly, without any backlight, additional light source, etc., so our eyes can see it clearly.
Is the direct-view LED display an ordinary LED display?
In fact, the direct-view LED display does not refer to an ordinary LED display but a more advanced display technology. Direct-view LED displays create text and images through an array of micro-pixel LEDs that directly emit color and light with higher brightness and contrast, as well as a better color range.
Ordinary LED displays, although they also use LED technology, may not be as good as direct-view LED displays in terms of pixel structure, brightness, contrast, etc.
Direct-view LED displays greatly improve resolution due to their fine pixel pitch and seamlessness and are particularly suitable for high-end applications such as large direct-view LED walls.
In general, direct-view LED displays are an advanced form of LED display technology that provides a better visual experience.
2. What are the characteristics and advantages of direct-view LED displays?
Speaking of direct-view LED displays, it is really a magical existence. Not only can it be used on various occasions, but it also has many unique advantages that make people shine. Let’s talk about its advantages.
1). High 輝度 and contrast make the picture come alive
Have you ever wondered why the content on those large LED screens is still clearly visible outdoors in the sun? This is due to the high brightness characteristics of LED displays. Its brightness is high enough to ensure that the picture is bright and not dim, even under strong light.
Moreover, the contrast of the LED display is also first-class, with clear black and white and rich colors, and it looks comfortable. In this way, whether you are watching advertisements outdoors or holding meetings indoors, you can enjoy a clear and sharp visual experience.
2). Energy saving and environmental protection, the choice of green life
Nowadays, everyone pays attention to energy saving and environmental protection, and LED display screens have done quite well in this regard. It is more power-saving and more environmentally friendly than traditional display technology.
Moreover, the life of LED display screens is particularly long and can be used for tens of thousands of hours! In this way, not only is the frequency of replacement reduced but a lot of maintenance costs are also saved. Choosing LED display screens is choosing a green and environmentally friendly lifestyle.
3). Wide applicability: Wherever you need it, you can move it
There are so many application scenarios for direct-view LED display screens. The billboards, traffic signs you see on the street, the display screens in the conference room, and even the TV wall at home may all be the “figure” of LED display screens.
It can not only adapt to various environments but also be customized according to different needs, which is really convenient.
4). Flexibility and customizability, creative space at will
When it comes to the flexibility of LED display screens, they are really unique. You can splice multiple display screens into any shape and size according to your needs, and you can assemble them however you want.
This flexibility not only makes installation and layout more convenient but also provides unlimited possibilities for various innovative applications. Imagine a giant ball screen composed of multiple LED display screens; how shocking it would be!
5). Fast response and リフレッシュレート, smooth dynamic images
If you like to watch e-sports games or live sports events, you must have high requirements for the smoothness of the picture.
The high refresh rate of LED display screens can meet your needs. Its refresh rate is particularly high, and it can update the picture many times per second so that the picture switching is faster and smoother.
Even if you watch a high-speed motion scene, there will be no smearing or blur. Such a visual experience is simply a kind of enjoyment!
In general, these characteristics and advantages of direct-view LED display screens make it a leader in modern display technology. It not only makes our visual experience clearer and more comfortable but also contributes to energy conservation and environmental protection.
With the continuous advancement of technology and the continuous expansion of applications, I believe that LED display screens will have more surprising performances in the future.
3. How are the classification and technological development of direct-view LED display screens?
As an important part of modern display technology, the classification and technological development of direct-view LED display screens show a trend of diversification and rapid iteration.
1). Classification by ピクセルピッチ
Direct-view LED display screens can be classified according to pixel pitch (that is, the distance between two adjacent LED pixels), mainly divided into small-pitch, medium-pitch, and large-pitch products.
- Small pitch (below P1.0):
The pixel pitch of this type of product is very small, usually below 1 mm or even smaller. The pixels of small-pitch LED display screens are very dense, which can present extremely high resolution and delicate picture effects. It is suitable for occasions that require high resolution and delicate display effects, such as high-end conference rooms, TV studios, etc.
- Medium pitch (P1.0-P2.5):
The pixel pitch of this type of product is between 1.0 mm and 2.5 mm, which is a more common type on the market.
Medium-pitch LED display screens have achieved a good balance between price and performance, which can meet certain resolution and display effect requirements without being too expensive. It is suitable for various commercial displays, billboards, stadiums, and other occasions.
- Large pitch (P2.5 or above):
The pixel pitch of this type of product is larger, usually above 2.5 mm. Although the resolution of a large-pitch LED display is relatively low due to its large pixel points, it can still maintain good clarity when viewed from a distance.
It is suitable for outdoor billboards, large stadiums, and other occasions that require long-distance viewing.
2). Technological progress
In recent years, with the continuous emergence of new technologies such as Micro LED and Mini LED, direct-view LED displays are developing towards higher resolution and finer pictures.
- Micro LED technology:
Micro LED is a new display technology based on micron-level LED chips. It has extremely high resolution, extremely low power consumption, and extremely long service life. Micro LED display can achieve seamless splicing and present a more delicate and realistic picture effect.
However, because Micro LED technology is currently facing challenges such as cumbersome manufacturing processes and high costs, it has not yet been commercialized on a large scale.
However, with the continuous advancement of technology and the gradual reduction of costs, Micro LED is expected to become one of the mainstream technologies for direct-view LED displays in the future.
- Mini LED technology:
Mini LED is a new display technology that is different from traditional LED and micro LED. It uses smaller LED chips, which can achieve higher brightness and contrast while reducing power consumption and cost.
Mini LED technology has been widely used in TVs, monitors, and other fields and has achieved remarkable results. With the continuous maturity of technology and further reduction of costs, Mini LED is expected to be more widely used in the field of direct-view LED display.
In summary, the classification and technological development of direct-view LED display screens have shown a trend of diversification and rapid iteration.
With the continuous emergence of new technologies and the continuous expansion of application fields, direct-view LED display screens will play a more important role in the future.
