LED ELECTRONIC DISPLAY SYSTEM FOR DISPLAYING IMAGE ON INCLINED LED ELECTRONIC DISPLAY

摘要

The purpose of the present invention is to provide an electronic display system that can rotate and output an image, which is outputted on an inclined installed electronic display, by one-degree unit. An LED electronic display system according to the present invention is characterized by comprising: a main controller (1); an electronic display (2) which is electrically connected to the main controller (1) and is composed by connecting a plurality of display units (2-1, 2-2, ... , 2-k); and a sub-controller (20) which is provided on each of the display units (2-k) and is for rotating and outputting an inclined image by using image and information data of the main controller (1), wherein the sub-controller (20) comprises: a first address generating unit (24) which sets a writing region for storing image data; a first register (25) for storing a vertex coordinate of a first region corresponding to an image to be outputted and a rotating angle () which are received from the main controller (1); a second address generating unit (26) which generates read addresses by means of calculation using the vertex coordinate and rotating angle stored in the first register (25) and a variable table value stored in a second register (27); and a memory control unit (28) which controls a memory (29), in which image data are stored, thereby reading and writing data.;COPYRIGHT KIPO 2020
