Display Device With Two-Dimensional Shared Lines For Controlling Distributed Driver Circuits

A method for operating a display device comprising:

• in an addressing mode, assigning addresses to driver circuits in an array of driver circuits based on addressing signals sent by a control circuit on a set of shared lines, the set of shared lines including row lines coupling driver circuits in respective rows of the array of driver circuits and column lines coupling driver circuits in respective columns of the array of driver circuits;
• in an operational mode, communicating, from the control circuit to the array of driver circuits distributed in a display area of the display device, driver control commands and readback commands on the set of shared lines, the driver control commands including an address of a targeted driver circuit;
• controlling, by the targeted driver circuit in response to the driver control commands, driver currents through one or more light emitting diodes in a light emitting diode zone;
• obtaining, from the control circuit, via the set of shared lines, readback data from the driver circuits in response to the readback commands;
• and
• adjusting, by the control circuit, the driver control commands in response to the readback data.

A display device comprising:

• light emitting means for generating light in response to respective driver currents;
• driving means distributed in a display area of the display device, the driving means for
• driving respective light emitting means with the respective driver circuits based on driver control commands and to generate readback data comprising sensed conditions in response to readback commands;
• control means for generating the readback commands, obtaining the readback data in response to the readback commands, and generating the driver control signals based at least in part on the readback data;
• and
• shared communication means for communicating the driver control commands and the readback commands from the control means to the driving means and to communicate the readback data from the driving means to the control means, the shared communication means including at least a first subset of shared communication means coupling driving means in respective rows and a second subset of the shared communication means coupling driving means in respective columns.
