LED has the advantages of small size, low power consumption, long life and environmental protection. In the actual production and development process, the reliability level of the LED chip needs to be evaluated through the life test, and the reliability level of the LED chip is improved through quality feedback. To ensure the quality of […]
The static and dynamic scanning of LED display screens correspond to each other. Generally speaking, real-pixel LED display screens refer to each of the red, green and blue light-emitting tubes that make up the display screen and only participate in the imaging of one pixel. To obtain sufficient brightness. Today, I will introduce the difference between static and scanning […]
In the LED electronic display, the driver IC’s role is to receive the display data in accordance with the protocol (from the receiver card or video processor and other information sources), produce internal PWM and current time variation, output and brightness and grayscale refresh related to the PWM current to light the LED. The display’s […]
