A distributed LED direct display control method and system

Abstract

This invention relates to the field of splicing display technology, specifically a distributed LED direct-view control method and system, comprising the following steps: acquiring module coordinates and calculating offsets to form sets according to network port order; reading whole-frame pixel segments and converting them into two-dimensional coordinates to generate a queue; matching horizontal and vertical offsets to determine modules and establishing mappings; reassembling data in sequence to form a transmission sequence; calculating display memory addresses, writing to the queue, and latching the display. In this invention, by establishing a spatial offset relationship between modules based on coordinate differences, the physical arrangement, cascading order, and data starting position are uniformly associated, enabling image distribution to shift from fixed segmentation to matching the actual layout, reducing misalignment and boundary issues. The data plane position is clearly defined based on two-dimensional coordinate indexes; horizontal and vertical offsets participate in boundary determination to improve addressing accuracy; the sequence is reassembled according to the transmission order and column coordinates, ensuring the connection order is consistent with image unfolding, reducing adjustment costs; and the data is directly written to and latched based on address calculations, enhancing data arrival certainty and display continuity.
