The standard for customers to buy high-quality LED display_commercial LED advertising screen|LED display manufactureru200b|LED floor tile screen

In recent years, LED display screens have been widely used in various fields such as indication, display, decoration, backlight, general lighting and urban night scenes. Roughly divided into: indoor LED display, outdoor LED display, commercial LED advertising screen, LED creative screen, stadium LED screen, LED floor tile screen, LED color screen, etc. Different companies have different sales strategies. Some companies focus on price wars. Materials, performance, and quality are often unsatisfactory. Don't be greedy for cheap, buy some low-quality and substandard products, and regret it. So how do consumers choose a product that they are satisfied with in the complex LED display industry environment? The following Huaze Optoelectronics will briefly summarize a few points for you as a reference for your screening: the most critical component of the LED display is the LED device . The general selection criteria are: high brightness, low working voltage, low power consumption, large-scale, long life, impact resistance and stable performance. Secondly, refer to: 1. The failure rate refers to the failure rate of the LED display screen from the beginning of assembly to aging 72 hours before shipment should not be higher than three ten thousandths (referring to the failure caused by the LED device itself) 2. The antistatic ability of the LED is Semiconductor devices are sensitive to static electricity and can easily cause static failure. Therefore, the anti-static ability is very important to the life of the display screen. Generally speaking, the failure voltage of the human body electrostatic mode test of the LED should not be less than 2000V. 3. Flatness The flatness of the surface of the LED display should be within 0≤a≤1mm to ensure that the displayed image is not distorted, partially convex or concave. Progress will cause a blind spot in the viewing angle of the display. 4. Brightness and viewing angle The brightness of the indoor full-color LED display must be above 800cd/m2, and the brightness of the outdoor full-color LED display must be above 1500?cd/m2 to ensure the normal display of the LED display, otherwise it will The displayed image cannot be seen clearly because the brightness is too low. If the environment is very bright, please use LED or rear projection first. The level of brightness is mainly determined by the quality of the LED die? The size of the viewing angle directly determines the size of the viewing area of u200bu200bthe LED display, so the larger the better. The size of the viewing angle is mainly determined by the LED chip. 5. White balance effect The white balance effect is one of the most important indicators of the LED display. In color science, pure white will be displayed when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16. If there is a slight deviation in the actual ratio, there will be a deviation of the white balance. The quality of the white balance is mainly determined by the LED chip. The LED chip also has an impact on the color reproduction. 6. Color reproducibility Color reproducibility refers to the color reducibility of the LED display screen. The color displayed on the LED display screen must be highly consistent with the color of the playback source, so as to ensure the realism of the image. 7. Whether there is mosaic or dead spots. Mosaic refers to the small four squares that are always bright or black that appear on the LED display, which is the phenomenon of module necrosis. The number of dead spots is mainly determined by the quality of the LED chip. 8. With or without color block Color block refers to the lack of color in a small area; the main reason is to control the IC, power supply, and control circuit cable quality. 9. The appearance of the LED display The appearance of the LED display is the most intuitive, the most primitive to make the most preliminary evaluation of the quality of the product. The appearance quality can reflect the quality of the production process and materials of the LED display manufacturer.
