Micro-LED display

A method for controlling a display device including an array of micro-LEDs that form individual pixels and a plurality of pixel logic hardware modules positioned proximate to corresponding micro-LEDs of the array of micro-LEDs, each pixel logic hardware module including a local memory element including a plurality of memory cells and a redundant memory cell, the method comprising:

• for each micro-LED of the array,
• determining if a memory cell of the plurality of memory cells is a degraded memory cell;
• based on determining that none of the plurality of memory cells is a degraded memory cell, during a local update sub-frame of a field time frame designated to visually present an image frame, writing a multi-bit pixel intensity value for the image frame to the local memory element of the pixel logic hardware module corresponding to the micro-LED;
• based on determining that a memory cell of the plurality of memory cells is a degraded memory cell, during the local update sub-frame of the field time frame designated to visually present the image frame, writing a bit of the multi-bit pixel intensity value to the redundant memory cell instead of the degraded memory cell based on said determining;
• and
• during a pixel modulation sub-frame of the field time frame, driving the micro-LED with a drive signal that is based on the multi-bit pixel intensity value for a pulse width modulation cycle that is repeated at a frequency of at least two pulse modulation cycles per the field time frame.

A display device comprising:

• an array of micro-LEDs forming individual pixels;
• a plurality of pixel logic hardware modules positioned proximate to corresponding micro-LEDs of the array of micro-LEDs, each pixel logic hardware module including a first local memory element and a second local memory element, wherein the first local memory element is configured to store a multi-bit pixel intensity value of a corresponding micro-LED for a first image frame, wherein the second local memory element is configured to store a multi-bit intensity value of the corresponding micro-LED for a second image frame that is visually presented by the display device subsequent to the first image frame, and each pixel logic hardware module being electrically connected to a corresponding micro-LED;
• and
• control logic configured to control an intensity of each micro-LED of the array according to a drive scheme that defines a first field time frame in which the display device visually presents the first image frame and a second field time frame in which the display device visually presents the second image frame.
