With the development of the market economy, the application range of LED displays will continue to expand. As a new type of information dissemination tool, LED display has been widely used in various industries. The long life, low power consumption, high brightness and other characteristics of LED light-emitting diodes are destined to become the first choice for large-screen information display applications. But at present, some people don't know the difference between outdoor LED display and indoor LED display. Let's explain the difference between the two.
Difference 1: The use environment is different. Indoor LED displays generally do not need to be waterproof or fireproof because of the location of use, while outdoor LED displays pose a challenge to the adaptability of products in diverse environments due to the diversity of use environments. The outdoor LED display is a system produced after combining the results of the external environment research and applying it to the preliminary design and the later maintenance. It is mostly used in large outdoor plazas, such as government plazas, leisure plazas, commercial centers, advertising information boards, commercial streets, railway stations, etc. Indoor LED displays are much better than outdoor environments. They are not affected by high temperatures and have no special requirements for waterproofing. Indoor LED displays have high requirements for air humidity. In southern my country, it is necessary to strengthen ventilation measures during the return to the southern season. Maintain a dry environment before and after the indoor LED display screen.
Difference 2: Different brightness requirements. Strong outdoor light leads to higher brightness requirements for the P4.81 outdoor rental LED display. P4.81 Outdoor rental LED displays are generally placed in the sun and exposed to direct sunlight. If the brightness is not handled well, or if reflection occurs, the viewing effect will definitely be affected.
Difference 3: The higher the suitable viewing distance of different pixels, the clearer the display and the larger the information capacity that can be contained, so the closer the suitable viewing distance. The P4.81 outdoor rental LED display has lower pixel density requirements than indoors. Because the observation is far away, the pixel density is low and the dot pitch is larger than indoors.
There are also differences between P4.81 outdoor rental LED display and half-indoor LED display:
The P4.81 outdoor rental LED display is manufactured with glue and then put on the kit, while the semi-outdoor LED display is not glued, and the waterproof function is not as good as that of the full outdoor;
P4.81 Outdoor rental LED display needs to be fully waterproof, semi-outdoor does not need to be waterproof;
P4.81 The brightness requirement of outdoor rental LED display is higher, and the brightness of semi-outdoor is generally sufficient;
The P4.81 outdoor rental LED display is made of a fully enclosed cabinet with high protection level; while semi-outdoors are mostly made of direct aluminum or simple cabinets, with a low protection level. The structure of the P4.81 outdoor rental LED display also requires waterproof planning, while the semi-outdoor LED display structure does not require waterproof planning. 6. Waterproof and moisture-proof should be the main consideration for all outdoor LED display screens, otherwise the circuit board may be damaged if water enters.
Regarding the hanging position, font size, and brightness, the P4.81 outdoor rental LED display must also consider the reflective brightness, or you can’t see the words on the screen during the day.
When exposed to high temperatures in summer, it will have a great impact on the P4.81 outdoor rental LED display. Take proper heat dissipation measures, and air conditioning must be installed for heat dissipation if the area is large.
The screen size, appearance and communication requirements, etc., P4.81 outdoor rental LED display and semi-outdoor are still somewhat different. For example, the size of the screen is subject to the environment of the scene, and the area of the semi-outdoor screen is generally not very large. The area of P4.81 outdoor rental LED display is almost unlimited.
Since P4.81 outdoor rental LED displays are different from the above two, they will also have a big difference in price. From the price composition of led displays, we can know their price difference.
P4.81 Outdoor rental LED display is mainly divided into three parts:
The main screen, the main screen is the display in the center of the stage. Most of the time, the shape of the P4.81 LED display is approximately square or rectangular. Due to the importance of its display content, the pixel density of the main screen is relatively high. The main display specifications currently used on the main screen are mainly P2.5, P3, P3.91, P4, P4.81, P5.
The secondary screen is the display used on both sides of the main screen. Its main function is to set off the main screen, so the content it displays is relatively abstract. Therefore, the models it uses are relatively large. Commonly used specifications are: P3.91, P4, P4.81, P5, P6, P7.62, P8, P10, P16 and other models.
Video expansion screens are mainly used in relatively large-scale occasions, such as large-scale concerts, singing and dancing concerts, etc. On these occasions, because the venue is relatively large, it is impossible to see the characters and people on the stage clearly in many places. Effect, so one or two large screens were installed on both sides of these venues. The content is generally live broadcast on the stage. Common specifications are similar to the main screen. The LED displays of P3, P3.91, P4, P4.81, and P5 are more commonly used.
