COORDINATE SCHEMES FOR ADDRESSING LED BASED MATRIX DISPLAYS

摘要

A display system (300) includes controllable lighting elements (330) having a control configuration; and a controller (310) configured to query the lighting elements (330) to determine their configuration. The controllable lighting elements (330) include LEDs. The controller (310) is further configured to translate input information into output information in accordance with the control configuration for control of the lighting elements, where the LEDs display a pattern in accordance with the output information. The pattern may be displayed by masking desired ones of the LEDs, where mask-based addressing compresses and reduces the size of the output information. The input and output information includes different coordinate addressing information.
