MY9268 - The best LED Driver solution for creating a high visual refresh rate multiplexing display
From concert to show event, FIFA to Olympic Games, we are always being amazed by the cutting-edge technology of LED display. With up to date photographic equipment and camera, traditional 240Hz refresh rate multiplexing LED panel cannot reach high end market anymore. Now, high refresh rate multiplexing is taking over the position. Dedicating to solve possible system difficulties, MY-Semi launches our innovative multiplexing LED driver IC solution to the market- MY9268.
Appearance of scan line annoys video taking, thus scan frequency must be faster than shutter time in order to avoid such issue. As a result, display refresh rate higher than 1,000Hz is required for high quality video shooting. Furthermore, loss of gray scale may also happen, root problem also comes too slow refresh rate. To ensure perfect screen performance, at least 4,000Hz refresh rate needs to be reached. In sport event, high speed camera enables delivery of LIVE sceneries to audiences; 8,000Hz refresh rate is thus requested. To sum up, high refresh rate is the key to next generation of high quality panel.
MY9268 is a 16-channel, 16-bit grayscale PWM driver IC with 8-bit Global Current Control. Reinforcing by “MPDM” (Multiplexing Pulse Density Modulation) technique patent pending, MY9268 is designed particularly for high refresh rate scan panel use. By interlacing scan images averagely, high refresh rate can be easily reached. In dynamic scan system, 16,000Hz and 8,000Hz refresh rate is achieved in 4 rows and 8 rows scan accordingly.
Comparing with traditional PWM driver, MY9268 raise LED driver IC cascading capability with its built-in memory. Thereby reduce cost of receiving card greatly. Thanks to MY-Semi’s latest innovation, Double-edge triggered grayscale clock, MY9268 successfully reduce EMI problem. One step forward to consider the ghost issue in multiplexing LED system, MY9268 offers double insurances avoiding such problem. Firstly, trigger MY9268 Automatic Black Frame Insertion and within adjustable period, pull output pin to high voltage, therefore ghost image is being abated.
