Factors related to brightness1. Ambient light conditions- Indoor environment: If the monochrome LED display is used in an indoor environment, such as an office or conference room, the ambient light is usually weak. In this case, there is no need for too high brightness, and a general brightness of 300-500cd/㎡ can meet the needs. Because too high brightness may cause visual discomfort indoors, and it will also increase unnecessary energy consumption and costs.- Outdoor environment: For monochrome LED displays used outdoors, such as in streets and squares, the ambient light is very strong due to direct sunlight. At this time, a higher brightness is required, usually requiring a brightness of 1500-2500cd/㎡ or even higher, so that the information on the display can still be clearly seen under strong sunlight.2. Visible distance- Close viewing: When the audience is close to the display, such as in some small indoor places, the visible distance is within 1-5 meters, and there is no need for too high brightness. Because at a close distance, even if the brightness is low, the audience can clearly see the content on the display. Generally speaking, a brightness of 400-800cd/㎡ is sufficient.- Long-distance viewing: In some large venues, such as stadiums and large squares, the distance between the audience and the display screen is far, which may reach tens of meters or even hundreds of meters. At this time, higher brightness is needed to ensure the legibility of the information. Usually, the brightness needs to reach 1000-2000cd/㎡ or more, so that the audience at a distance can see the content on the display screen clearly.Resolution factors1. The degree of refinement of the displayed content- Simple text information: If the monochrome LED display is mainly used to display simple text information, such as digital clocks, simple notifications, etc., the resolution requirements are relatively low. For example, in some factory workshops, it is used to display production data, and only the characters need to be clearly identifiable. At this time, a lower resolution display can be selected, such as a P4 or P5 model display with about 17,200 pixels per square meter.- Complex graphics or small font text: When complex graphics or small font text need to be displayed, a higher resolution is required. For example, in some financial trading places, detailed transaction data and complex charts need to be displayed, so it is necessary to choose a high-resolution display screen, such as P2.5 or higher resolution models with about 64,000 pixels per square meter, so as to ensure the clarity and accuracy of graphics and text.2. Matching viewing distance with screen size- Small screen close-up viewing: For smaller-sized monochrome LED displays, if they are viewed at close range, such as displays with an area of 1-2 square meters used in small conference rooms, the viewing distance is about 2-5 meters, and a higher resolution is required to ensure the delicate degree of display effect. You can choose P2-P3 resolution specifications.- Large screen long-distance viewing: In some large-screen monochrome LED displays used in large places, such as outdoor displays with an area of more than 10 square meters, the viewing distance is far, at 10 meters or even farther. At this time, the resolution can be relatively reduced, such as choosing P6-P8 resolution specifications, because when viewed from a distance, the human eye's sensitivity to resolution will decrease, and lower-resolution displays can also meet visual needs while reducing costs.Reliability and stability factors1. Working environment- Temperature and humidity: If the monochrome LED display will be used in an environment with large temperature and humidity changes, such as in the open air without shelter, the temperature may be as high as 40℃ or above in summer and as low as -10℃ or below in winter, and the humidity will also fluctuate greatly. This requires the selection of a display that can adapt to such harsh environments, and its electronic components should have good high temperature resistance, low temperature resistance and moisture resistance. For example, industrial-grade chips and housings with high protection levels are used.- Dust and vibration: In some industrial production environments, such as machinery factories and construction sites, there is a lot of dust and vibration. For monochrome LED displays in such environments, good dust and vibration resistance is required. You can choose a display with a sealed design to prevent dust from entering the internal circuit. At the same time, the structure of the display should be made of sturdy materials and a reasonable fixing method to resist the impact of vibration.2. Service life and maintenance cost- LED lamp bead quality: LED lamp beads are the core components of monochrome LED displays, and their quality directly affects the service life of the display. High-quality LED lamp beads have a longer lifespan, generally up to 50,000 - 100,000 hours. For example, some well-known brands of lamp beads have better performance in terms of luminous efficiency, stability and lifespan.- Driving circuit and power supply stability: The stability of the driving circuit and power supply is crucial to the reliability of the display. A stable driving circuit can ensure that the LED lamp beads emit light normally and reduce the occurrence of faults. A high-quality power supply can provide stable voltage and current to avoid damage to the display due to power supply fluctuations. When choosing a monochrome LED display, pay attention to the brand and quality of its driving circuit and power supply, and try to choose products with good reputation and quality assurance.Cost factors1. Budget constraints- Low-budget projects: In some projects with limited budgets, such as small community activity centers, small shops, etc., it is necessary to reduce costs as much as possible while meeting basic display needs. At this time, you can choose a monochrome LED display with relatively low resolution and brightness but high cost performance. For example, some domestic low-end products have advantages in price and can meet the simple display needs of these places, such as displaying basic notifications, advertising information, etc.- High-budget projects: For some projects with high requirements for display effects and sufficient budgets, such as large commercial centers, high-end office buildings, etc., you can choose higher-end monochrome LED displays. These displays have better performance in terms of brightness, resolution, reliability, etc., but the price is also relatively high. For example, some products of internationally renowned brands have invested heavily in technology research and development, product quality and after-sales service, and the product price is higher, but they can provide better visual experience and more reliable performance.2. Long-term operating costs- Energy consumption: Although monochrome LED displays are relatively energy-efficient, there are still differences in energy consumption between different models and specifications. When choosing, consider the power consumption of the display, especially for displays that need to run for a long time, such as in places such as railway stations and airports. For example, choosing a display with an efficient power management system can reduce energy consumption, thereby reducing long-term operating costs.- Maintenance cost: In addition to the purchase cost, maintenance cost is also a factor that needs to be considered. Some poor-quality displays may require frequent replacement of parts, increasing maintenance costs. Although good-quality displays have high purchase costs, they have relatively low maintenance costs during their service life. For example, choosing a display screen with good after-sales service and easy-maintenance design can reduce long-term operating costs.
