Dynamic LED matrix lighting control using scanning architecture |
摘要 |
This invention is a new LED back lighting architecture that each individual LED is controlled by its associated LED drive cell. The LEDs are sequentially connected one after another. A host controller transmits image displaying signals by signal scanning-flows. The current flow for controlling each LED's color lighting is by either binary current flow control or two-steps progressive current flow control.
