Abstract
The present invention discloses a method for driving a full-color LED display board with high resolution. It features three original color LED pixels that are arranged in a diamond pattern to form LED array, and an interlacing scan circuit is used to control the LED array. As a result, the display of a new pixel can be inserted between two contiguous pixels and the resolution of the full-color LED display board increases.
Claims4
A method for driving a full-color LED display board with high resolution, comprising the steps of:
- providing a full-color LED display board including a first LED array, wherein the first LED array has a plurality of first LED pixels arranged in a diamond pattern, and each first LED pixel has a top LED dot, a bottom LED dot, a left LED dot and a right LED dot;
- outputting odd dot signals of odd rows and even dot signals of even rows of an image to be displayed onto the first LED array;
- and
- outputting odd dot signals of even rows and even dot signals of odd rows of the image to a second LED array, wherein the second LED array includes a plurality of second LED pixels arranged in a diamond pattern, each second LED pixel has a right LED dot of a left adjacent first LED pixel, a left LED dot of a right adjacent first LED pixel, a bottom LED dot of a top adjacent first LED pixel and a top LED dot of a bottom adjacent first LED pixel.
