Ultra-long strip screen application: using led screen controller from Huidu technology. The total number of points of the ultra-long strip screen is not very large, but the width is very long. Generally, the led screen control system of small and medium-sized screens cannot meet the width load requirements, and the cost of large-scale control systems is very high. How to solve the loading of the ultra-long strip screen at the lowest cost, which requires the use of an asynchronous discount control scheme.
In the practical application of the strip screen, in order to maximize the function of the receiving card, the multi-open connection method is often used, which not only improves the display effect, but also reduces the equipment cost.A series of products discount notes:The canvas resolutions supported by the A series are as follows:(576, 4096), (640, 3728), (768, 3096), (864, 2736), (1056, 2176), (1280, 1864), (1472, 1564), (1760, 1344), (1920 , 1080), (1920, 1232), (2176, 1120), (2432, 992), (2688, 864), (2816, 816), (3072, 782), (3200, 720), (3712, 642 ), (3840, 600);As shown in the canvas resolution above, if the A-series products are discounted by 1024 dots, the display resolution width after the discount should be calculated as 1056; if the discount is 2560 dots, the display resolution width after the discount is 2688 Calculation.
