What factors should be paid attention to when purchasing indoor LED displays

November 30, 2022

Nowadays, indoor LED display screens have gradually become an indispensable publicity medium, especially in densely populated areas such as banks, hotels, supermarkets, hospitals, etc., where there are many people coming and going, and a striking reminder board is necessary. The indoor LED display has played a very good role in helping.

For different occasions, the size of the LED display is not the same, users should also pay more attention to the following details when purchasing.

1. LED display material

2. LED display power consumption


4.Viewing distance

5. Installation environment

6.Pixel pitch

7.Signal transmission equipment

8.Low light and high gray


1. LED display material

The material quality of LED display is the most critical. The quality of materials used in the production of indoor LED full-color displays mainly refers to the LED lamp core, module power supply, IC driver, control system, packaging technology and cabinet, etc. Some other equipment used mainly include: computer, audio power amplifier, air conditioner, power distribution cabinet, multi-function control card, and users in need can also be equipped with TV card and LED video processor. In addition, the manufacturing process of the display screen and the packaging technology of the lamp are also important considerations.

2. LED display power consumption

Generally speaking, indoor LED displays have very low power consumption, and they will not consume too much power for long-term use. However, for bulletin boards with relatively large screens, such as banks and stock halls, high-strength LED displays are required. For the LED display, not only the subtitles must be cleaned and visible, but uninterrupted is also the focus of our consideration.

3. Brightness

Considering the limited installation area of the indoor LED display, the brightness is much lower than outdoors, and in order to take care of the adaptation process of the viewer’s human eyes, the brightness must be adaptively adjusted, which is not only more energy-saving and environmentally friendly, but also can meet the needs of the viewer. Set off for human adjustments.

4. Viewing distance

The dot pitch of indoor LED displays is generally below 5mm, and the viewing distance is relatively short, especially the viewing distance of small-pitch LED screens can be as close as 1-2 meters. When the viewing distance is shortened, the requirements for the display effect of the screen will also be improved, and the presentation of details and color reproduction must also be outstanding without giving people an obvious sense of graininess, and these are the advantages of large LED screens.

5. Installation environment

The working environment temperature range of LED display is -20℃≤t≤50℃, and the working environment humidity range is 10% to 90%RH; avoid using it in adverse environments, such as: high temperature, high humidity, high acid/alkali/salt and other harsh environments ;Keep away from flammable materials, gas, dust, pay attention to use safety; ensure safe transportation to prevent damage caused by bumps during transportation; avoid high temperature use, do not open the screen for a long time, and should be properly closed to let it rest; LEDs with more than specified humidity When the display is powered on, it will cause corrosion of components, or even short circuit and cause permanent damage.

6.Pixel pitch

Compared with traditional LED screens, the outstanding feature of indoor small-pitch LED screens is the smaller dot pitch. In practical applications, the smaller the dot pitch, the higher the pixel density, the more information capacity that can be displayed per unit area at one time, and the closer the viewing distance is. On the contrary, the longer the viewing distance is. Many users naturally think that the smaller the dot pitch of the purchased product, the better, but this is not the case. Conventional LED screens want to achieve the best visual effect and have the best viewing distance, and the same is true for indoor small-pitch LED screens. Users can make a simple calculation through the best viewing distance = dot pitch/0.3~0.8, for example, the best viewing distance of P2 small-pitch LED screen is about 6 meters away. maintenance fee

Generally speaking, the larger the size of the display screen of the same model, the higher the purchase cost, and the higher the maintenance cost, because the larger the display screen size, the more complicated the maintenance process, so it is necessary to fully Combined with the on-site environment to make the display screen of the optimal size, it can save maintenance costs while showing the best effect.

7. Signal transmission equipment

In order to ensure efficient and convenient application of indoor small-pitch LED screens, the support of signal transmission equipment is indispensable. A good signal transmission equipment must have the characteristics of multi-signal unified display and centralized data management, so that the display screen can be used for smooth and convenient transmission and display.

8. Low light and high gray

As a display terminal, indoor LED screens must first ensure viewing comfort. Therefore, when purchasing, the primary concern is brightness. Relevant studies have shown that in terms of the sensitivity of the human eye, as an active light source, LEDs are twice as bright as passive light sources (projectors and liquid crystal displays). In order to ensure the comfort of human eyes, the brightness of indoor LED screens The range can only be between 100 cd/m2-300 cd/m2. However, in the 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 judging the high-quality indoor LED screen is to achieve “low brightness High gray” technical indicators. In actual purchase, users can follow the principle of “the more brightness levels that can be recognized by the human eye, the better”. The brightness level refers to the brightness level of the image from the blackest to the whitest that the human eye can distinguish. The more brightness levels are recognized, the larger the color gamut of the display screen and the greater the potential for displaying rich colors.

9. Resolution

The smaller the dot pitch of the indoor LED screen, the higher the resolution and the higher the clarity of the picture. In actual operation, users want to build the best small-pitch LED display system. While paying attention to the resolution of the screen itself, it is also necessary to consider its collocation with front-end signal transmission products. 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 several Therefore, in order to avoid waste of resources, users must choose according to their needs when purchasing indoor LED screens, and avoid blindly catching up with trends.

At present, the indoor full-color LED display products produced by MPLED are widely used in hotels, financial enterprises, cultural and entertainment enterprises, sports halls, traffic guidance, theme parks, mobile applications and other occasions. Our indoor products WA, WS, WT, ST, ST Pro and other series and models can meet your various needs.
