  • Reasons to choose outdoor LED advertising display
    I remember reading this line in an article: "The Internet has eaten everything. It has eaten television, it has eaten print, it has eaten newspapers, music and books. But it has not and will never eat outdoor media." Many outdoor LED billboards have become a beautiful landscape, integrated with urban buildings and become part of the landmark! Outdoor large LED screen advertisements have been sticking to their posts for many years. Some people may think that they are used to its existence and have little effect on themselves. However, when shopping, he will think of this outdoor advertisement, and even choose to buy the product. Therefore, we found that outdoor advertising does not have no effect on consumers. In fact, they have memories of the content of the advertisement, and the audience receives the content of the advertisement unconsciously. When exposed to the product again, short-term memory kicks in, influencing its final decision. Outdoor advertising has a subtle impact on consumers' psychology, leaving an impression in consumers' subconscious, thus playing a role in consumers' purchasing decisions. Under the premise of making full use of the media scene environment and space, outdoor LED large-screen advertising can mobilize a variety of on-site expression methods to create a comprehensive and rich sensory stimulation, images, sentences, three-dimensional objects, dynamic sound effects, environment, etc. can be combined ingeniously. At the same time, using AR interactive 3D naked eye and other technologies, the large-screen media interacts with the mobile Internet terminal, realizing a seamless connection between offline and online.

  • How much is the led electronic display screen?
    Many friends will be concerned about the price when purchasing LED screens, but there are many factors that affect the price of LED screens. The low price is one thousand yuan per square meter, and the expensive one is tens of thousands per square meter. see it 1. LED Display specifications From the color, the LED display can be divided into dan color, two-color, full-color, and from the use environment, it can be divided into indoor, outdoor, semi-outdoor, and the price of each type of led screen is different. LED Displays with the same point spacing are generally more expensive outdoors than indoors. Outdoor led screen will be equipped with technical requirements such as waterproof, dustproof, and sunscreen. 2. LED Display model Generally, the smaller the point spacing, the clearer the point, and the higher the natural price. For example, the price of P3 led screen will be higher than that of P5 led screen. 3. LED Screen Display area The larger the area, the higher the price will naturally be. 4. LED Screen Display shape Common special-shaped screens are cylindrical, round, square or Rubik's cube, etc. The more difficult the shape, the more expensive the price; 5. LED Display raw materials Among the raw materials, light-emitting chips (light tubes) are currently the main factor affecting the price of LED screens. In addition, there is also LED driver IC, which is a very important factor affecting the quality and life of the led display. If the led display screen is used in very important occasions, it is recommended to choose imported light-emitting chips, constant current and constant voltage driver ICs to be more secure. Other materials that affect the price are power supplies, cabinets, and various accessories for making led displays. 6. LED Display supporting system a. System accessories: sending card, receiving card, transfer card; b. Playing system: control computer, multimedia card or graphics card, playing software; c. Editing system: editing computer, video compression card, editing software; d. Monitoring system: sensor + monitoring software; e.

  • Transparent LED screen Selection Guide , How to choose size and model
    Transparent LED screen have become a rising star in the display field, and naturally become one of the popular choices for users in many industries. However, in the actual demand process, factors such as model, size, and viewing distance need to be comprehensively considered, which undoubtedly makes it more difficult for users to recognize. Let's talk about the factors that need to be paid attention to when choosing LED transparent display. Transparent LED Display Selection Guide and Points to Note: 1. The dot pitch and resolution are closely related, and product selection should pay attention to the application In the current small-pitch LED market, permeability, dot pitch, large size and resolution are the key points of manufacturers' technical PK. In practice, these factors also affect each other, and the specific dot spacing must be matched with the appropriate transparent screen size to achieve the best display effect. 2. The selection of LED transparent screen brightness Full indoor display. Including: indoor stage, exhibition hall, conference room, etc. The indoor light is dim, and the brightness of the transparent LED display should be controlled between 800-1500nits. It is recommended not to exceed this brightness range. If it is too bright, it will appear too dazzling, affect the viewing effect, and also consume more electricity. Semi-outdoor display. Including: shopping malls, sales offices, etc. The semi-outdoor light environment is better than indoors, and the brightness selection should be controlled at about 2000-3500nits to ensure the normal display effect of the transparent screen. When the LED transparent screen faces no sunlight, it is perfectly satisfied according to the customer's environment of 3000CD-4500nits; when the LED transparent screen faces the sun, the low-brightness transparent screen will appear blurred pictures due to insufficient brightness. The brightness selection should be around 5000-6000nits to meet the normal display effect in a strong sunshine environment. 3. Large-sized products must fully consider maintenance costs In practical applications, not only the high purchase cost but also the maintenance cost should be considered when selecting large-size products. Although the theoretical life of LED lamp beads can reach 100,000 hours, because high-density LED transparent screens are mainly used in indoor applications, the products are required to be light and thin, and the thickness should be low. , it will make it difficult to dissipate heat, and the probability of local failure will be high. In actual operation, the larger the screen size is, the more complicated the maintenance will be, and the maintenance cost will increase accordingly. Therefore, for large-size products, users must choose on demand. 4. The combination of signal transmission equipment cannot be ignored The signal compatibility of the LED transparent screen is very important. If the signal access requires a variety of requirements, the number is large and the location is scattered, it usually includes video signals in H.264, 720P, 1080P and other formats. When purchasing a product, you should avoid paying attention to the product unilaterally. The resolution must be fully considered whether the existing signal equipment supports the corresponding video signal.

  • Outdoor LED display considerations
    In the outdoor LED large screen environment, the quality requirements are higher, and there are many factors to be considered. 1. From the perspective of the application of LED large screen, LED large screen full color screen is the mainstream in the future. Because of the high brightness and full color, it can work all day, but the price is high. 2. From an application point of view, there is a reason for a product that meets user needs. Due to its cheap price, maturity and stability, the dual-primary color display has a large market in terms of no blue characters and color display. 3. The direction and distance of the outdoor screen play a decisive role in the price. The farther away, the larger the pixel and the brighter it is. Displays in the northeast are much less expensive than those in the southwest. 4. The joint between the screen and the building must be strictly waterproof and leak-proof. The filter should adopt good drainage measures, and once there is accumulated water, it can be discharged smoothly. 5. Install lightning protection devices on LED displays and buildings. The display body and the casing are well grounded, the grounding resistance is less than 3, and the large current caused by lightning can be discharged in time. 6. Install ventilation equipment for cooling to ensure that the internal temperature of the screen is between -10-40. A fan can also be installed at the rear of the screen to dissipate heat. 7. Select an industrial-grade integrated circuit chip with a working temperature of -40-80 to prevent the screen from not starting when the temperature is too low in winter.

  • Characteristics of Several Different LED Display Modules
    According to the different surface treatment technology of LED display screen, we can divide it into plug-in module, table-mounting module, sub-table-mounting module, three-in-one table-mounting module and three-in-one table-mounting module. Plug-in module It refers to the DIP encapsulated lamp which passes the lamp foot through the PCB board and fills the tin in the lamp hole by welding. The module made by this process is the plug module. The advantages are large angle of view, high brightness and good heat dissipation. The disadvantages are low pixel density. Surface mount module SMT, also known as SMT, solders the SMT encapsulated lamp on the surface of PCB board by welding process, the lamp foot does not need to pass through the PCB board, and the module made by this process is called SMT module. The advantages are: large perspective, soft display image, high pixel density, suitable for indoor viewing; the disadvantages are that the brightness is not high enough, and the lamp tube itself does not heat well. Subsurface Mounting Module It is a product between DIP and SMT. The packaging surface of LED lamp is the same as SMT, but its positive and negative pins are welded through PCB in production as DIP. Its advantages are high brightness, good display effect, and its disadvantages are complex process and difficult maintenance. Three-in-one table sticker It refers to encapsulating three different colours of LED wafers, R, G and B, in the same colloid. The advantages are: simple production, good display effect, and disadvantage: difficult spectrophotometry and high cost. Three-in-one sticker It refers to the vertical juxtaposition of three independent packaged SMT lamps, R, G and B, according to a certain distance, which not only has all the advantages of the three-in-one, but also solves all the disadvantages of the three-in-one. From the above classification, we can see that different classification modules have their own advantages and disadvantages, so when we make the LED display screen, we should classify according to the actual application situation and the scene situation.

  • IP Protection Level of LED Display Screen
    The IP (International Protection) protection level system for LED display screen was drafted by IEC (International Electro Technical Commission). The lamps and lanterns are classified according to their characteristics of dust-proof, foreign invasion-proof, waterproof and moisture-proof. The objects referred to here include tools, human fingers and so on. They can not touch the charged part of the lamp, so as to avoid electric shock. IP protection level is composed of two numbers. The first number represents the level of dust-proof and foreign invasion prevention of lamps and lanterns, and the second number represents the degree of sealing of moisture-proof and water-proof invasion of lamps and lanterns. The bigger the number, the higher the level of protection. The two numbers indicate the level of protection as follows: IP protection level: The first indication of the degree of protection indicated by the characteristic number (number) The first number is: 0 unprotected IP0- 1. Prevent solid objects larger than 50mm from intruding and human body (such as palm) from accidentally touching parts inside lamps. Prevent large size (diameter greater than 50mm) objects from intruding into IP1- 2. Prevent solid objects larger than 12 mm from intruding into the lamp and prevent human fingers from touching the parts inside the lamp. Prevent medium-sized (diameter greater than 12 mm, length greater than 80 mm) objects from intruding into IP2- 3. Prevent the intrusion of solid objects larger than 2.5mm, tools, wires or similar small objects larger than 2.5mm in diameter or thickness from touching the interior parts of lamps IP3- 4. Prevent the intrusion of solid objects larger than 1.0 mm, tools, wires or similar small objects larger than 1.0 mm in diameter or thickness from touching the interior parts of lamps and lanterns IP4- 5 Dust-proof, completely prevent foreign invasion. Although it can not completely prevent dust intrusion, the amount of dust intrusion will not affect the normal operation of lamps IP5- 6. Dust tightness completely prevents foreign matter from intruding, and also completely prevents dust from intruding into IP6- The second indicates the degree of protection indicated by the characteristic number (number) The second indicator number: 0 unprotected IP-0 with no special protection for people or objects outside 1. Prevent drip intrusion. Vertical drip (e.g. condensate) will not cause harmful effects on lamps and lanterns IP-1. Dripping water can still be prevented when the lamp is inclined to 15 degrees. When the lamp is inclined from vertical to 15 degrees, dripping water will not cause harmful effects on the lamp IP-2. 3. Prevent the invasion of sprinkled water, prevent rain or water sprayed in the direction of vertical angle less than 60 degrees from entering the lamps, causing damage to IP-3 4. Prevent splashing water from intruding into lamps, and prevent splashing water from entering lamps in all directions, causing damage to IP-4 5. Prevent the water from spraying into the lamp and damage IP-5 by spraying water from all directions. 6. Prevent the intrusion of big waves, install lamps on deck, and prevent the damage IP-6 caused by soaking due to the invasion of big waves. 7. Prevent water intrusion during immersion. Lights immersed in water for a certain time or under a certain water pressure can ensure that IP-7 is not damaged by water inflow. 8. Prevent water intrusion during sinking, and ensure that IP-8 is not damaged by water inflow under the condition of specified water pressure for indefinite sinking of lamps and lanterns.

  • Analysis of Performance Indicators of LED Display Screen
    LED display has been developing rapidly in the world since the 1980s, and its performance indicators have been gradually improved and improved. At present, the performance indicators of all aspects of LED display have reached a new level. Performance indicators are more responsive to user needs. Key performance indicators of LED display: 1. Maximum output current: At present, the maximum output current of the mainstream constant current source LED driver chips is about 90 mA per channel. It is more meaningful for the display screen to output the maximum constant current at the same time in each channel, because in the white balance state, it is required that each channel output the constant current at the same time. 2. Number of Constant Current Output Channels: Constant Current Source Output Channels have 8-bit and 16-bit specifications. Now 16-bit occupies the mainstream. Its main advantage lies in reducing chip size, facilitating the wiring of the LED driver board (PCB), especially for the LED driver board with smaller point spacing. 3. Accurate current output: one is the current error between the same chip channels; the other is the output current error between different chips. Accurate current output is a key parameter, which has great influence on the display uniformity of LED display. The larger the error is, the worse the display uniformity is, and it is difficult to achieve white balance of the screen. At present, the bit to bit current error of mainstream constant current source chips is generally less than (+3%) and the chip to chip current error is less than (+6%). 4. Data shift clock: It determines the transmission speed of display data, and is the key index affecting the update rate of LED display screen. As a large size display device, display refresh rate should be above 85Hz to ensure a stable picture (no scanning flicker). High data shift clock is the basis of high refresh rate screen acquisition. At present, the shift clock frequency of the mainstream constant current source driver chips is generally above 15MHz to 25MHz. The greatest advantage of LED display is that it can be manufactured without the limitation of area, and can reach tens or even hundreds of square meters. It can be used to display text, graphics, images, animation, video and other information in indoor and outdoor public places. With the improvement of various performance indicators of LED display, the application of LED display will be realized. More widely distributed, the function will be more powerful.

  • "Anti-aging" Magic Way of Full-color LED Display Screen
    With the development of science and technology, LED advertising screen has developed from the original monochrome display to the full-color LED display screen nowadays. Full-color media also have the advertising characteristics of high effective arrival rate and relatively low price. Unlike traditional outdoor media, it has both the characteristics and advantages of TV and other media, and has greater creative space and advantages. The broader space for interaction and communication with consumers in time and space can meet the individual needs. It has the concept of communication in the digital age and is a unique form of screen. When we use led, we often have such problems. The LED display screen works normally at the beginning of the product, but after a period of lighting, there will be dark light, flashing, failure, intermittent lighting and other phenomena, which will bring serious damage to the product. The reasons for this phenomenon are as follows: when applying products, there are some problems in welding process, such as too high welding temperature, too long welding time, and not doing a good job of anti-static work. More than 95% of these problems are caused by the packaging process. Or the quality of the LED itself or the manufacturing process. The prevention method is simply aging test. Aging is an important guarantee for the reliability of electronic products and the last essential step in the production of products. LED products can improve the efficiency after aging, and help to stabilize the efficiency of later use. Aging test of LED advertising screen is a very important link in product quality control, but it is often neglected in many cases and can not carry out correct and effective aging. The aging test of LED is based on the characteristics of the failure rate curve, i.e. bathtub curve, to improve the reliability of the product, but this method is not necessary. After all, the aging test of LED is at the expense of the life of a single LED product, including constant current aging and constant pressure aging. Constant current source means that the current is constant at any time. The problem of frequency is not constant current. That's AC or pulsating current. AC or pulsating current sources can be designed with constant RMS, but they can not be called constant current sources. Constant current aging is the most scientific way to aging LED, which is in line with the working characteristics of LED current. Overcurrent shock aging is also the latest aging method adopted by LED display manufacturers. It is carried out by using constant current source with adjustable frequency and current, in order to judge the quality life expectancy of LED in a short time, and can be selected. Many hidden dangers of conventional aging can not be identified by LED. So the friends who are going to buy full-color LED display screen must wipe their eyes and choose a good supplier. It is not feasible to be too small, and there is basically no aging test link out of the factory. Only after the factory aging test will the old slowly.

  • What causes the aging of full-color LED screen?
    What is the meaning of aging test for full-color LED screen? When we use full-color LED screen, we often encounter such problems. The full-color LED screen works normally at the beginning of the product, but after a period of lighting, there will be dark light, flashing, failure, intermittent lighting and other phenomena, which will cause serious damage to the product. The cause of this phenomenon: What is themeaning of aging test for full-color LED screen? When we use full-color LED screen, we often encounter such problems. The full-color LED screen works normally at the beginning of the product, but after a period of lighting, there will be dark light, flashing, failure, intermittent lighting and other phenomena, which will cause serious damage to the product. The reasons for this phenomenon are as follows: 1. In the application of products, there are some problems in the welding process, such as too high welding temperature, too long welding time, and no anti-static work. More than 95% of these problems are caused by the packaging process. 2. The quality of full-color LED screen itself or the production process. Preventive measures are: 1. Control the welding process well. 2. Aging testing of products: Aging is an important guarantee for the reliability of electronic products and the last essential step in the production of products. LED products can improve the efficiency after aging, and help to stabilize the efficiency of later use. The aging test of full-color screen is a very important link in product quality control, but it is often neglected in many cases and can not carry out the correct and effective aging. LED aging test is based on the characteristics of the product failure rate curve, that is, the bathtub curve, to improve the reliability of the product, but this method is not necessary, after all, aging test is at the expense of the life of a single LED product. The aging methods of full-color LED screen include constant current aging and constant pressure aging. Constant current source means that the current is constant at any time. The problem of frequency is not constant current. That's AC or pulsating current. AC or pulsating current sources can be designed with constant RMS, but they can not be called constant current sources. Constant current aging is the most scientific way to aging LED, which is in line with the working characteristics of LED current. Overcurrent shock aging is also the latest aging method adopted by the manufacturers of full-color LED screens. This kind of aging is carried out by using constant current source with adjustable frequency and current, in order to judge the quality life expectancy of LED in a short time and select the right one. Many hidden dangers of conventional aging can not be picked out by full-color LED screen.

Environmental protection: LED display materials are made of materials that are environmentally friendly, which are recyclable and will not pollute or destroy the environment due to heavy use. 8. Small calorific value: LED display is LED, because the power of single LED is low, generally 0.04~0.08 W, so the heat is not high. It can be used as a decorative lighting in a fish tank, without producing a large amount of heat and causing the water temperature to rise, affecting the growth of ornamental fish. If have calorific value also is normal, because of the need to use electric, will inevitably produce a certain quantity of heat, therefore, breakthrough, large companies have begun to gradually improve the heat problem developed can reduce heat radiator, fan. This greatly reduces the heat generated by the work of LED displays. Nine, wide application range: LED display because of characteristics such as light, the color is pure, is widely used in building outline, the steps, booth, bridge, hotel, KTV decorative lighting, as well as the production of advertising signs, all kinds of large animation, calligraphy and painting of advertising design and so on.
