. High-Speed Refresh Technology
1. Innovation Vision's high-speed refresh technology addresses the inherent differences between LEDs and CRTs. CRT phosphors exhibit a relatively long afterglow when bombarded by an electron beam, while LEDs have a much faster photoelectric response, reaching nanosecond levels. Therefore, LED displays have significantly higher requirements for refresh duty cycle and refresh rate than CRT monitors and televisions.
2. Innovation Vision's high-speed refresh technology allows the display screen to achieve a refresh rate of 800-2000 Hz/second, with a refresh duty cycle approaching 1, using a static refresh method. This ensures that viewers experience no flickering, water ripples, or other undesirable phenomena, whether viewing the entire image in static or dynamic conditions. Viewers can comfortably watch the content displayed on the screen for extended periods without fatigue. Early LED display control system designs used the same progressive scan method as televisions for refreshing display data signals. This resulted in image distortion when displaying fast-moving images. These phenomena are visually apparent, manifesting as what we commonly see – high-speed object movement causing image discontinuity or jagged edges, etc.
3. To overcome these challenges, Innovationview Technology Co., Ltd. has adopted frame refresh technology in its LED full-color display screen control system design. This means the display screen refreshes the entire screen simultaneously, rather than line by line, eliminating the delay between transmitting the first line and subsequent lines, improving image reproduction quality. It can also be used in conjunction with high-speed cameras to prevent distortion when displaying fast-moving images.
II. Faroudja's New Broadcast System Technology Innovationview's newly developed Faroudja broadcast system technology offers a complete set of advantages for progressive scanning: color crosstalk suppression technology, adaptive progressive scanning for each pixel's movement, directional correction progressive scanning, movie mode, or 3:2 and 2:2 pulldown.
III. Color Crosstalk Suppression Technology (CCS) InnovationView's proprietary color crosstalk suppression technology addresses color crosstalk caused by poor decoding of composite video. CCS eliminates residual angular information from the luminance signal, enabling 2D decoding systems to achieve the same effect as 3D decoding systems, eliminating image flicker and maintaining optimal color accuracy.
IV. 3D Motion Adaptive Noise Reduction Technology This true 3D noise filtering technology differs from other low-level filtering techniques. It avoids a weak or lifeless image. Dynamic adaptive operation is linked to progressive scan algorithms and dynamic detection to prevent "ghost trails" and blurred images. Skin tone sensitive filtering uses different techniques in skin tone areas to eliminate "plastic faces" and distortion of image details, reducing noise by 6-10 dB without causing rainbow effects or reducing image clarity.
