How to quickly select high-quality LED display screens?p2.5 rental indoor led display

　　LED display screens have been widely used in various fields such as indication, display, decoration, backlight, general lighting, and urban night scenery in recent years. It can be roughly divided into: indoor LED display screens, outdoor LED display screens, LED commercial advertising screens, LED creative screens, LED stadium screens, LED tile screens, LED color screens, etc.

　　Different companies have different sales strategies. Some companies mainly engage in price wars, where materials, performance, and quality are often unsatisfactory. Don't be greedy for cheap prices and regret buying low-quality and substandard products.

　　So how can consumers choose a product that they are satisfied with in the complex LED display industry environment? Below, Beijing Runxian Technology will briefly summarize a few points for your reference in screening:

　　The most critical component of LED display screens is LED devices. The general selection criteria are: high brightness, low working voltage, low power consumption, large-scale, long service life, impact resistance, and stable performance.

　　Secondly, we also need to refer to:

　　1. Inefficiency

　　The failure rate of LED display screens from assembly to 72 hours of aging before shipment should not exceed 3/10000 (referring to the failure caused by the LED device itself)

　　2. Antistatic ability

　　LEDs are semiconductor devices that are sensitive to static electricity and are prone to electrostatic failure. Therefore, their anti-static ability is crucial for the lifespan of display screens. Generally speaking, the failure voltage of LED's human electrostatic mode test should not be lower than 2000V

　　3. Flatness

　　The surface flatness of LED display screens should be within 0 ≤ a ≤ 1mm to ensure that the displayed image does not distort. Local protrusions or indentations may cause blind spots in the visual angle of the display screen.

　　4. Brightness and visual angle

　　The brightness of indoor full color LED display screens should be above 800cd/m2, while the brightness of outdoor full color LED display screens should be at 1500? Above cd/m2 is necessary to ensure the normal display of the LED display screen, otherwise the displayed image may not be clear due to low brightness. If the environment is very bright, please prioritize using LED or rear projection. The brightness is mainly determined by the quality of the LED tube.? The size of the viewing angle directly determines the amount of visible area space of the LED display screen, so the larger the better. The size of the visual angle is mainly determined by the LED chip.
