Color, brightness and viewing angle are gradually upgraded with the combination of diode system and semiconductor, and its production materials and manufacturing processes have been gradually upgraded, breaking the original brightness and color limitations. A large number of blue diodes and pure green light-emitting diodes are used to enhance the brightness of the display.
Furthermore, the advantages of outdoor LED display screens in outdoor environments are improved, which can adapt to different display requirements and enhance the effective value of LEDs in different environments. The evaluation of outdoor LED display performance must be the result of comprehensive consideration, because its related performance indicators are closely related, and indicators such as brightness, viewing angle, and resolution affect each other. At present, surface mount LED devices are used in high-density, full-color indoor displays to improve the viewing angle and brightness performance of the display.
