Abstract
A LED controller includes an image buffer to hold image data. An LED pixel forming a part of a large pixel array is activatable in response to image data, LDO state, and pulse width modulation module state. A logic module including a pixel diagnostic mode using an LDO bypass is connected to modify LDO state and allow direct addressing of the LED pixel for diagnostic purposes without needing to use image data from the image buffer.
Claims7
A LED controller, comprising:
- an image buffer to hold image data;
- an LED pixel activatable in response to image data, LDO state, and pulse width modulation module state;
- and
- a logic module including a pixel diagnostic mode using an LDO bypass connected to modify LDO state and allow direct addressing of the LED pixel without image data from the image buffer.
