2. Comparison of technical characteristics
1). Brightness and visibility
1.1). Indoor LED screen:
- Suitable brightness:
Designed specifically for indoor environments, the brightness is moderate to protect the audience’s vision while ensuring a clear display under various light conditions. The screen uses high-efficiency LED chips and color calibration technology to keep the picture bright and details clear even under indoor lighting.
- Intelligent brightness adjustment:
Some high-end indoor LED screens have intelligent ambient light sensing functions, which can automatically adjust the screen brightness according to the intensity of indoor light to achieve the best visual effect and save energy.
1.2). Outdoor LED screen:
- Brightness adjustment strategy:
In response to the diversity of outdoor environments, outdoor LED screens are usually equipped with brightness adjustment functions, but they may focus more on quick response and flexibility.
For example, when used on a moving vehicle, the brightness needs to be adjusted in real-time according to the vehicle’s speed and driving environment to ensure effective communication of the advertisement.
- 节能技术：
In order to cope with the energy consumption challenges that the outdoor environment may bring, outdoor LED screens will also incorporate a variety of energy-saving technologies in the design, such as low-power LED chips, smart sleep modes, etc., to ensure the display effect while reducing energy consumption. Consumption.
2). Waterproof and dustproof grade
2.1). Indoor LED screen:
- Suitable for indoor environments:
Given that the indoor environment is relatively stable, indoor LED screens usually do not need to reach high IP protection levels. However, in order to ensure long-term stable operation, dustproof designs, such as sealed box structures and easy-to-clean surface materials, will still be used to prevent dust accumulation from affecting the display effect.
2.2). Outdoor LED screen:
- Special waterproof and dustproof design:
For portable or temporary outdoor LED screens, although they may not need to reach the same IP protection level as outdoor LED screens, special designs will be used to ensure basic waterproof and dustproof capabilities. For example, waterproof connectors and sealed interface designs can be used, and the screen surface can be covered with a waterproof and dustproof film.
3). Thermal performance
- Silent and efficient heat dissipation:
Indoor LED screens focus on the balance of heat dissipation and silence.
The use of efficient heat sinks, heat pipes, natural convection, and other heat dissipation methods ensures that the screen temperature is stable during long-term operation while reducing noise interference and improving the comfort of the indoor environment.
For high-brightness or large-size screens, fans may also be equipped to assist cooling, but the noise level will be strictly controlled. Outdoor LED screen:
- Heat dissipation optimization strategy:
Outdoor LED screens may pay more attention to lightweight and portability in heat dissipation design. Therefore, a more compact heat dissipation structure and lightweight materials will be used without affecting the heat dissipation effect.
At the same time, corresponding heat dissipation optimization strategies will be formulated for specific climate conditions (such as high temperature, high humidity, etc.), such as increasing the speed of cooling fans, optimizing air duct design, etc.
3. Differences in application scenarios
1). Indoor LED poster screen:
- Brand stores and shopping malls:
In indoor commercial spaces, LED poster screens have become a powerful tool for brand display and product promotion. They can display brand image, product features, and promotional information in high definition, attract customers’ attention, and enhance the shopping experience.
In specialty stores or shopping malls, the flexibility and interactivity of LED poster screens enhance customers’ sense of participation and promote sales conversion.
