Did you buy the right indoor and outdoor LED display?

When selecting and applying Shenzhen LED display, the key points are in these aspects, and the following will give you an explanation:
1. Detailed description of the life of indoor LED electronic screen
The service life is 100,000 hours. The technical documents produced by the LED raw material manufacturer indicate that the life of the LED luminous object is 100,000 hours under ideal conditions. The ideal situation means that the LED luminous object will never shine under the condition of constant voltage and constant current power supply in the laboratory. By the time it does not shine at all, 100,000 hours will be converted into 11 years. The LED display screen currently uses civilian-grade components, and its application life span does not exceed 8 years.

The function of the LED display is the display function. When the LED display is on and can only be seen at night, it cannot be explained that it is up to the standard and has the value of the commodity. A car can run for 15 years, and if it is not used for 3 years, it will be charged. The natural environment and method of application are quite harmful to the life span of the product.

2. Price selection of indoor LED electronic screens
The choice of LED display depends on the comparison of the use effect and not simply on the price. Because the prices on the sales market are too chaotic at this stage, many prices are not even the cost of people’s products, which indicates that the raw materials used are not very good, so when customers buy goods, they must grasp the company’s status and a display screen. How much is the cost and price, customers can not only pay for the goods, but pay attention to the useful life and display effect of the LED display.

The LED display is the ultimate fusion of high-tech and news media. It can vividly present the core concepts of beauty and fashion, and it can completely become a new force in stage design, in new stage performances and outdoor advertising. Ways continue to appear, from traditional LED billboards, to solid-color word-moving screens, to today’s wonderful LED displays. With the development trend of the LED manufacturing industry, outdoor media advertising methods have become more and more fashionable, and may become the development trend of urban new media in the next few years.

At this stage, most of the KTV nightclubs, etc. install ultra-clear displays in the rooms. Outdoor LED displays have already occupied 80% of the outdoor media advertising industry’s market share, becoming a new carrier of large and medium-sized outdoor media advertising. 160-degree angle, broadcast-level color saturation, LED color temperature and chromaticity are intelligently adjustable, which is more suitable for long-term watching.

Three main points that must be clear when choosing a small-pitch LED display

In the field of LED display in 2017, the small-pitch LED display has become a well-deserved star product, and its market application scope is expanding rapidly. For users, although they are not unfamiliar with small spacing under the promotion of manufacturers, they are still not sure about how to choose products that suit their requirements. Then, when purchasing small-pitch LED products, what are the key points that users should pay attention to in order to maximize the investment benefits while meeting the needs of use?

1.”Low brightness and high gray” is the premise:

As a display terminal with a small-pitch LED display, the first thing to ensure is the comfort of viewing. Therefore, when purchasing, the primary concern is the brightness issue. Relevant studies have shown that, in terms of human eye sensitivity, LED as an active light-emitting source, its brightness is twice that of passive light-emitting sources (projectors and liquid crystal displays), and to ensure the comfort of human eyes, the small-pitch LED screen The brightness range can only be between 100 cd/m2-300 cd/m2.

However, in traditional LED display technology, reducing the brightness of the screen will cause the loss of grayscale, and the loss of grayscale will directly affect the picture quality. Therefore, an important criterion for high-quality small-pitch LED displays is to achieve ”      “Low brightness and high gray” technical indicators

In actual purchase, users can follow the principle of “the more brightness levels that human eyes can recognize, the better”. The brightness level refers to the brightness level of the image that the human eye can distinguish from the darkest to the whitest. The more the recognized brightness level, the larger the color gamut space of the display screen, and the greater the potential for displaying rich colors.

2.Select the point spacing and pay attention to the balance between “effect and technology”

Compared with the traditional LED screen, the outstanding feature of the small-pitch LED display is the smaller dot pitch. In practical applications, the smaller the dot pitch, the higher the pixel density, the more information capacity per unit area can be displayed at one time, and the closer the distance suitable for viewing. On the contrary, the longer the distance suitable for viewing. Many users naturally think that the smaller the dot pitch of the product, the better. However, this is not the case.

Conventional LED screens want to achieve the best visual effects and have the best viewing distance. The same is true for small-pitch LED screens. Users can make simple calculations through the best viewing distance=dot pitch/0.3~0.8. For example, the best viewing distance of the P2 small-pitch LED display is about 6 meters away.

We know that the smaller the dot pitch, the higher the cost of the small-pitch LED screen. Therefore, in actual purchase, users must comprehensively consider their own cost, demand, application range and other factors.

3. Choose the resolution, pay attention to the match with the “front-end signal transmission equipment”

 The smaller the dot pitch of the small-pitch LED screen, the higher the resolution, and the higher the picture definition. In actual operation, users want to build the best small-pitch LED display system. While paying attention to the resolution of the screen itself, they must also consider the combination of it and the front-end signal transmission product.

For example, in security monitoring applications, the front-end monitoring system generally includes video signals in D1, H.264, 720P, 1080I, 1080P and other formats. However, not all small-pitch LED screens on the market can support the above. Therefore, in order to avoid waste of resources, users must choose according to their needs when purchasing small-pitch LED screens, and avoid blindly following the trend.

At present, small-pitch LED products have been widely used in TV studios, power system monitoring centers, aerospace command centers, military command centers, government halls, urban monitoring centers, video conference rooms, dispatch rooms, airports, train stations, hotels, and large Medium-sized enterprises and other occasions.
