LED screen companies: Regardless of the stormy seas, only a "strong channel" can allow you to roam freely!

In recent years, the LED display screen market has been changing rapidly and there have been many variables. However, no matter how the market fluctuates, at this stage, for LED displays, which are "engineering-type, durable" products, the advantage of product differentiation is becoming increasingly prominent. For LED screen companies to maintain a leading edge in the market, they must have their own unique product advantages. In addition, the strong driving system of "marketing + channels" cannot be relaxed in the slightest, especially strengthening channel construction... In fact, the business logic of the entire Chinese LED display screen industry has always been driven by strong marketing and powerful channels, maintaining market leadership with continuous scale advantages, and then establishing corresponding phased leading advantages in the terminal market with differentiated products and innovative technologies. Ultimately, a brand-based foundation centered on comprehensive strength is formed, and on this basis, more leading strategies in technology, fine products, and services are actively explored. Among them, "strong channels" are of great importance to the market competitiveness and significance of many LED screen companies. Recently, including Leyard, Lianjian, and Unilumin, LED screen companies have successively "returned" to the wholesale channel market. In addition to the increasingly saturated terminal market, the situation of increasing volume but not increasing profits in the LED display screen industry is becoming increasingly severe. Although some screen companies maintain relatively stable gross profit margins through scale and technological innovation, the market's contribution to the profits of screen companies is very limited, and the importance of channels is particularly prominent at this time. More and more LED display screen companies are beginning to switch to the development model of "strong channels". However, building good channels is not something that can be achieved overnight. On the one hand, when the LED display screen industry is in a critical period of transformation and upgrading, the core of strong channels has shifted from the initial blind pursuit of channel scale to quality optimization development based on a certain scale. Nowadays, whether it is first-tier or second-tier cities, or third-, fourth-, fifth-, sixth-tier cities and even counties and towns, brand influence, product shipment volume and quality assurance, and service capability optimization are the key to channel construction for screen companies. On the other hand, the sales model and channel expansion methods of the current LED display screen market are becoming increasingly diversified. LED screen companies need to follow the trend and choose channel development methods that suit their own actual situation, and must not blindly follow the trend. At the same time, they cannot blindly pursue brand marketing while forgetting that the ultimate buyers of LED display products are customers, not distributors. Ignoring the strengthening of terminal management and service quality improvement will make it difficult for screen companies' channels to truly become "strong". Currently, the LED display screen industry includes many sub-fields. With the improvement of LED display screen product technology, the LED display market has been further expanded, including advertising media, commercial display, stage rental, and various special applications. Among them, each field includes low-, mid-, and high-end applications. For high-end engineering application projects, the direct sales model is obviously more competitive, while for the mid- and low-end market with improved overall product quality, channels are absolutely the "king" of the industry. No matter how the overall industrial environment develops and changes, for LED screen companies, their business laws have never changed, that is, to return to the origin, win over users, provide products, achieve profits, and achieve rolling development. In short, "obvious product advantages, unique channels, and accurate marketing positioning" are the key to the development of LED screen companies in the future!

How about LED large screens? What are their features?

LED screens are ubiquitous, appearing in shopping malls, subway stations, hospitals, and many other places. However, not everyone understands their inner workings. An LED screen displays characters, text, graphics, animations, and videos by controlling the on/off states of semiconductor light-emitting diodes (LEDs), typically combinations of red, green, and blue LEDs. What are its characteristics? LED screens are suitable for various public places. The frequent appearance of LED screens reflects their advantages. They are effective for advertising, announcements, and other promotional uses in public areas. They can be used for advertising campaigns, as traffic guidance system displays, and in many other applications due to their versatility, rich functionality, and durability. LED screen technology is advanced and impressive. Many people know that LED screen technology is comparable to CRT technology, enabling quick ad content changes, large screen sizes, high-resolution images, high brightness, rich colors, and diverse display modes for text, graphics, videos, and both 2D and 3D animations. Importantly, the presence of LED screens showcases development strength, enriches people's lives, and improves a city's intelligence level, making it more welcoming to residents. After learning about LED screens, it's clear that they are superior products, offering excellent technology, rich colors, and high-quality images, suitable for both indoor and outdoor use, and worth considering.

Precautions for selecting small-pitch LED displays

Small-pitch products feature high refresh rate, high grayscale, high brightness utilization, no ghosting, low power consumption, and low EMI. They are non-reflective for indoor applications, lightweight, ultra-thin, high-precision, space-saving for transportation and use, quiet, and efficient heat dissipation. Small-pitch LED displays are widely used in indoor and outdoor smart advertising machines, stage performances, exhibitions, sports events, hotel lobbies, and various other occasions. Among them, P1.66 and P1.9, which are representative of small-pitch displays, have become the most popular products. Some may ask, since we are choosing small-pitch displays, why not choose those with even smaller pixel pitches? This question clearly indicates a lack of understanding in selecting small-pitch LED displays. Let's learn more together. Traditionally, people believe that pixel pitch, large size, and high resolution are the key elements determining a small-pitch LED display, believing that the best of each is always the best choice. However, in practice, these three factors influence each other. In other words, for small-pitch LED displays, the best application effect is not simply achieved by the smallest pixel pitch and highest resolution. Instead, it requires comprehensive consideration of factors such as screen size and application space. Currently, the smaller the pixel pitch and the higher the resolution of small-pitch LED displays, the higher the price. If users do not fully consider their application environment when purchasing products, they may end up spending a lot of money without achieving the desired application effect. Indoor LED display, A prominent advantage of small-pitch LED displays is "seamless splicing," which can fully meet the large-size display needs of industry users. However, in practical applications, industry users need to consider not only the high procurement cost but also the high maintenance cost when choosing large-size small-pitch products. Although the lifespan of LED beads can reach 100,000 hours, due to their high density and the requirement for low thickness in indoor applications of small-pitch LED displays, heat dissipation can easily become difficult, leading to local failures. In practice, the larger the screen size, the more complex the repair process, and the higher the maintenance cost. In addition, the power consumption of the display should not be underestimated, and the later operating cost of large-size displays is generally higher. The issue of multiple and complex signal inputs is different for indoor and outdoor applications of small-pitch LEDs. Indoor signal input has diverse requirements, including a large number of signals, dispersed locations, multiple signals displayed on the same screen, and centralized management. In practice, for efficient application of small-pitch LED displays, signal transmission equipment cannot be overlooked. In the LED display market, not all small-pitch LED displays can meet the above requirements. When purchasing products, avoid focusing solely on the resolution and fully consider whether the existing signal equipment supports the corresponding video signals. Shanghai Lexian focuses on the LED display industry and has rich R&D and industry solutions to provide professional solutions. Small-pitch LED displays attract users with clearer detail display and realistic image effects. During the purchasing process, customers must comprehensively consider their application needs to achieve the best desired use effect.

What is a double-sided LED display screen?

There is a type of display screen called a double-sided flip, which is widely used in the field of outdoor media advertising and is highly praised by users! Do you know what an LED double-sided flip display screen is? Below, we will introduce the concept, product functions, and characteristics of the LED double-sided flip display screen. I. Introduction to the LED Double-Sided Flip Display Screen. The LED double-sided flip display screen is a combination of a three-sided flip billboard and an LED electronic display screen. Its working principle is as follows: one of the three images on the original three-sided flip prism is replaced with an LED display module, while the other two sides still use screen-printed images. In this way, it alternately displays two screen-printed images during the day, and at night, it automatically turns out the LED display module to play video images, equivalent to a conventional LED display screen. II. Functions. The LED double-sided flip display screen not only has the effect of a three-sided flip but also the effect of an LED display screen, fully leveraging the advantages of both. Two painted images can be displayed during the day, and its function is equivalent to a conventional LED display screen at night, which can play various video files and support live television broadcasts. III. Advantages. The traditional three-sided flip is a semi-dynamic outdoor advertising medium. Its advantage lies in its ability to display large-area advertisements at a relatively low cost and accommodate more advertising content than static billboards. Its semi-dynamic display effect, realistic colors, and huge size leave a deep impression on the audience, resulting in outstanding advertising effects. However, it cannot display a complete dynamic image. The display content is limited to three images, and the night-time effect is poor. Lighting equipment is needed to highlight the advertising content. Traditional display screens can display multiple images, completely dynamic images, but the effect is not ideal under strong direct sunlight, the initial investment cost is high, energy consumption is high, the later operation cost is high, and the service life is short. The LED double-sided flip display screen overcomes the shortcomings of both. During the day, the three-sided flip is used to overcome the poor effect of the LED display screen during the day. The aging and attenuation of LED lights and chips working under high temperatures and harsh environments lead to a shorter service life. The effect of the LED display screen at night merely utilizes the superior display effect of the LED display screen at night, overcoming the defect that the three-sided flip needs external lighting to illuminate the advertising screen. It fully leverages the advantages of both, achieving optimal advertising space, minimum investment, the best product combination, and the highest return! IV. Product Features. 1. Screen-printed images are displayed during the day, and screen-printed image A and screen-printed image B are alternately displayed. 2. The three-sided cross-section belongs to a general cross-sectional specification. 3. At night, the LED display automatically turns out to play video images equivalent to a conventional LED display screen. 4. The overall structure has good compatibility with traditional three-sided flips, making it easy to achieve simple grafting of the display screen and the three-sided flip billboard. 5. Supports front maintenance, and the LED display screen has a modular design that is easy to install and disassemble. 6. When LED display modules are installed on the three-sided flip, it ensures that any light-emitting diodes are arranged uniformly, achieving image integrity. 7. The LED display screen can play various texts, animations, and full-color video images, and the content can be changed at any time, reflecting multimedia functions. 8. It has good outdoor performance, with comprehensive performance such as dustproof, moisture-proof, salt-spray resistant, rainproof, snowproof, electromagnetic interference-proof, and lightning-proof. 9. The power consumption is only one-eighth of that of conventional display screens. There is no dedicated heat dissipation device at night, using protective modules, resulting in low later operating costs and a long service life. V. Application Scope. It can not only be used as a commercial advertising display platform but also as a perfect platform for various levels of government departments to conduct public welfare propaganda and legal publicity. Suitable for large shopping malls, rooftops, walls, squares, commercial centers, crossroads, pedestrian streets, etc. Its modular design is easy to disassemble and reinstall, allowing consumers to change the installation location as needed, making it widely applicable.

Five points to note about LED screens

1. Dead Pixels LED display dead pixels refer to individual pixels that are constantly lit or dark on the display. The number of dead pixels is mainly determined by the quality of the LED chips. Fewer dead pixels result in better display quality. 2. Brightness Brightness significantly impacts indoor LED displays. Excessive brightness can harm eyesight and health, while insufficient brightness leads to unclear images. Generally, the brightness of indoor LED displays should be between 800cd/㎡ and 2000cd/㎡, although this varies among different brands. 3. Color Reproduction Color reproduction refers to how accurately the display reproduces the colors of the source, ensuring image realism. 4. Flatness The flatness of the display affects image quality. The surface flatness of indoor LED rental screen cabinets is generally within ±1mm. Local protrusions or indentations on the cabinet surface can create blind spots in the viewing angle. Flatness is determined by the manufacturing process, which should be carefully controlled by LED display manufacturers. 5. Viewing Angle The viewing angle of an LED display directly determines its audience reach. A larger viewing angle is better, allowing for a wider audience. The viewing angle is affected by the LED chip packaging method. Therefore, the chip packaging method should also be considered when choosing indoor LED rental screens.

How do naked-eye 3D LED screens trick your eyes?

Since 2020, naked-eye 3D screens have gradually entered the public eye. From the wave tank in Seoul, South Korea, to the spaceship in Chengdu Taikoo Li, and the tricolor cat in Tokyo Shinjuku, naked-eye 3D screens have attracted countless people from all over the world. Compared with traditional 3D displays that require glasses or helmets, naked-eye 3D screens, which can be viewed without any equipment, seem to have a natural advantage. However, behind the naked-eye 3D screen, is it technological advancement or a visual trick? Human eye parallax/How to deceive the eyes to produce a 3D effect? As early as 1839, British scientist Wheatstone was pondering a question - "Why is the world we observe three-dimensional?" After research, he found that because there is a distance of about 6.5 cm between human eyes, when observing three-dimensional objects, the perspectives are slightly different, which produces binocular parallax. The left eye sees the left side, and the right eye sees the right side. There is a slight difference in the images seen. The object is imaged on the retina at the same time. The brain compares the two different "images" to distinguish the distance of the object, thus producing a three-dimensional effect. The effect that causes this three-dimensional sensation is called "visual displacement." It is this visual displacement that allows us to distinguish the distance of objects and obtain a three-dimensional sense of depth. When observing an object with both eyes simultaneously, each point on the object has an angle to both eyes. The closer the object is to the eyes, the larger the angle of each point on the object to the eyes, and the greater the visual displacement. The farther the object is from the eyes, the closer the lines of sight of the two eyes are to parallel, and the visual displacement is close to zero. It is difficult for us to judge the distance of the object, and we will not have a three-dimensional sense of it. Looking at the stars at night, it feels like all the stars are on the same spherical surface, and it is difficult to distinguish the distance. This is the result of zero visual displacement. Visual displacement is the basic principle of 3D movies producing a three-dimensional effect: during shooting, two cameras are used to shoot simultaneously, obtaining two synchronized images with differences. Then, polarized glasses are used to separate the content for the viewer's left and right eyes, so that the two eyes obtain different images for the left and right eyes respectively. In this way, there is a three-dimensional effect, and what is presented in the brain is the feeling of a 3D image. Naked-eye 3D screens also utilize the characteristics of human eye parallax, projecting the pixels corresponding to the left and right eyes to the left and right eyes respectively, thus producing a three-dimensional image, allowing viewers to feel the three-dimensional effect at a specific angle. How does "visual illusion" deceive the brain to produce a three-dimensional effect? The three-dimensional effect of a plane image is caused by the "visual illusion" processed by the brain, or the brain supplements the three-dimensional effect. When the brain processes plane images, it will calculate the distance and spatial sense. If the image does not provide enough information, the brain will actively supplement the depth when trying to judge the spatial depth of the image. Just as painters use the distance, size, shadow effects, and perspective relationships of objects in a two-dimensional image to construct a three-dimensional effect, making the brain misjudge the spatial sense and depth of the image, 3D video sources also use perspective and shadow relationships to expand and confuse spatial perception, causing visual illusions in the human eye, thus producing a realistic three-dimensional effect. Most plane naked-eye 3D screen video sources use the visual illusion of significant frames. When the brain selects obvious frames as distance reference objects, the dynamic image suddenly blocks the "front" and "back" of the frames, or the contrast between far and near is highlighted, forming an illusion of brain distance judgment, thus producing a three-dimensional effect. Most of the current popular naked-eye 3D screens are corner screens, which use two adjacent plane screens to present different sides of a three-dimensional object. They use spatial perspective and the imaging properties of two adjacent sides of a corner screen to create visual illusions of light and shadow, brightness and darkness, and reality and virtualness for the human eye, making the screen content appear three-dimensional. Each 3D video source needs to be customized according to parameters such as screen shape, size, and viewing angle. First, the optimal viewing angle is determined, then video content conforming to the perspective principle is created according to the viewing angle, then the box layout diagram of the display screen is used for corner positioning, and finally, a video source that presents a three-dimensional effect at a specific angle is output. Because the video source is created based on a specific angle to simulate the 3D effect, only by standing at a specific angle can you obtain the optimal viewing angle of the three-dimensional effect. If you are not standing at the optimal angle, the screen content will be deformed. This is why the shooting angles of most naked-eye 3D corner screens are the same, because only at a specific angle can you see the best 3D effect. In order to achieve perfect integration of creative content and the real environment and create an immersive 3D experience, designers need to customize video sources that conform to the perspective principle according to the on-site installation scene of the display screen. The closer the boundaries of the video content are to the real scene, the more realistic the three-dimensional effect will be for the audience. Hardware requirements and display effects of naked-eye 3D screens depend on screen hardware conditions From the perspective of hardware devices, not all outdoor LED screens are suitable for naked-eye 3D effects. The display effect of naked-eye 3D screens has high requirements for screen quality, installation precision, and creative reality materials. To present better 3D video effects, LED screens must meet at least the following three requirements. Seamless transition: The mainstream 3D large screens on the market are mainly corner screens and curved screens, and true seamless corner screens are preferred. Seamless transitions can better integrate two adjacent plane large screens, bringing a visual experience with stronger spatial sense and three-dimensionality. High-definition images: Outdoor high-definition large screens have become the direction of development, and 8K resolution and small spacing are becoming mainstream, with spacing developing from the original P16, P10, P8 to P6, P3.9, and even P2.5. The smaller the spacing, the more delicate the screen display effect, and the more realistic the 3D effect. Immersive effect: Compared with ordinary outdoor advertising screens, naked-eye 3D displays pursue more stable images and realistic colors. Excellent screen quality can present more image details and bring a more immersive visual experience. Impressive naked-eye 3D screens often have "three high" characteristics. High refresh rate: 3840Hz and higher refresh rates ensure higher image stability; High grayscale: 16bit (i.e., 65536 color changes) ensures more delicate color changes, avoiding color difference or discontinuity; High contrast: The maximum brightness of 10000nits ensures that the image remains visible under direct sunlight and presents more details and purer colors. Naked-eye 3D screen trends, domestic and foreign layout At present, naked-eye 3D is mainly distributed in the CBD business districts of some large and medium-sized cities, achieving the purpose of attracting customers for commercial entities and creating city landmarks. For cities, successfully integrating 3D content with local culture will bring huge traffic and exposure to the city, creating a popular check-in location. With the popularity of naked-eye 3D screens worldwide, overseas markets also favor naked-eye 3D outdoor large screens. Naked-eye 3D large screens can be seen in countries such as the United States, the Netherlands, the Philippines, and Thailand. Compared with traditional LED screens, naked-eye 3D screens, which have built-in hotspots and traffic, are obviously more popular with customers and advertisers. However, as more and more naked-eye 3D outdoor advertising cases appear and the screen content becomes homogenized, high-quality displays are the key to maintaining the popularity of naked-eye 3D screens, thus bringing continuous advertising benefits.
