As SMD/LED display technology continues to advance, higher refresh rates such as 1920Hz, 3840Hz, and even 7680Hz have become increasingly common. While the human eye cannot easily distinguish between these refresh rates directly, the choice largely depends on the intended application and viewing environment. 1920Hz: Ideal for Outdoor Advertising The 1920Hz refresh rate is widely used in outdoor SMD/LED screens, particularly for digital out-of-home (DOOH) applications like advertising billboards and video walls. Since outdoor viewers typically observe screens from a distance ranging from 10 to 200 meters, 1920Hz is generally sufficient for delivering a visually acceptable experience. It also offers a more budget-friendly option, considering the balance between performance and cost of the control ICs. 3840Hz: Best for Indoor and Close-Range Viewing For indoor applications such as live events, concerts, and stage performances where audiences are closer to the display and often use cameras or smartphones to capture footage a higher refresh rate of 3840Hz is recommended. This level helps minimize flicker in recorded videos and improves visual clarity. It’s especially essential for fine-pitch displays (below 2.5mm), GOB (Glue on Board), COB (Chip on Board) technology, and 3D naked-eye SMD/LED screens, where precision and quality are key. 7680Hz: Designed for Virtual Production and High-End Media In high-end productions involving 3D SMD/LED screens, camera tracking systems, or virtual sets, a 7680Hz refresh rate ensures seamless synchronization with camera movements. This ultra-high refresh rate reduces artifacts like moiré patterns and scan lines, producing clearer footage that closely resembles what the human eye naturally perceives. It’s especially useful in media production, filmmaking, and promotional content where image quality is critical. Summary 1920Hz: Cost-effective and suitable for outdoor, long-distance viewing. 3840Hz: Recommended for indoor, short-range use, particularly when filming is involved. 7680Hz: Optimal for virtual production, 3D displays, and professional media capture. Choosing the right refresh rate depends on the specific needs of your application, including viewing distance, content type, and whether the display will be filmed.
