Display system having monitoring circuit and methods thereof

A method of maintaining a modular multi-panel display that includes a mechanical support structure and a plurality of LED display panels detachably coupled to the mechanical support structure without a cabinet, wherein each LED display panel has a data port that is bidirectionally coupled to at least one other LED display panel, the method comprising:

• monitoring each of the plurality of LED display panels;
• determining that a defective LED display panel has a defective LED pixel based upon a result of the monitoring, wherein the monitoring and determining is performed by a monitoring circuitry comprising a power failure detecting circuit and a camera, wherein the monitoring comprises periodically activating the camera to capture an image and processing the image, and wherein the determining comprises identifying a dark pixel, wherein a dark pixel is a pixel having a lower brightness than an associated brightness to be displayed for the pixel;
• and
• removing the defective LED display panel by hot swapping the defective LED display panel from the mechanical support structure.

A method of maintaining a modular multi-panel display, the method comprising:

• electronically monitoring each of a plurality of light emitting diode (LED) display panels by using bidirectional communication with a network interface card having a unique Internet Protocol (IP) address inside each of the LED display panel, wherein each of the plurality of LED display panels is individually attached to a common frame, wherein the plurality of LED display panels is attached to the frame without cabinets, wherein each of the plurality of LED display panels includes a power supply coupled to a power line that extends along a group of the LED display panels;
• during operation of the modular multi-panel display, electronically identifying a LED display panel is a defective LED display panel by determining that the power supply of the identified LED display panel is not providing a power output for powering the defective LED display panel;
• and
• removing the defective LED display panel by hot swapping the defective LED display panel from the common frame.
