Modular display panels

A modular light-emitting diode (LED) display sub-assembly comprising:

• a front side and an opposite back side, wherein the front side of the modular LED display sub-assembly comprises a display surface of the modular LED display sub-assembly;
• a frame comprising a top horizontal member, a bottom horizontal member, a left vertical member, and a right vertical member;
• a plurality of modular LED display panels attached to the frame, wherein all of the plurality of modular LED display panels have a substantially rectangular perimeter and the same length, width, height, and shape, wherein each of the plurality of modular LED display panels comprises:
• attachment points facilitating attachment of the modular LED display panel to the frame;
• a printed circuit board comprising a first side and an opposite second side;
• a driver circuit electrically coupled to the printed circuit board;
• a casing attached to the opposite second side of the printed circuit board;
• and
• a plurality of LEDs arranged as pixels and attached to the first side of the printed circuit board, wherein the pixels are arranged in a rectangular array comprising at least fifty pixels as part of the display surface, and wherein
• each of the pixels of the rectangular array is a surface mount device (SMD) module comprising a plurality of LED devices and a top surface, the top surface being exposed to an external environment,
• each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch, the pitch is a predetermined constant number, and each of the plurality of the modular LED display panels being configured to be swapped with another modular LED display panel having a pitch different from the pitch of a modular LED display panel being swapped while having the same height as the height of the modular LED display panel being swapped and the same width as the width of the modular LED display panel being swapped.

A modular light-emitting diode (LED) display panel comprising:

• attachment points for use in attachment as part of a multi-panel modular LED display;
• a printed circuit board comprising a first side and an opposite second side;
• a water-sealed plastic casing attached to the opposite second side of the printed circuit board, a perimeter of the water-sealed plastic casing being substantially rectangular and having a height and a width;
• a driver circuit electrically coupled to the printed circuit board, the driver circuit being directly attached to the opposite second side of the printed circuit board, wherein the water-sealed plastic casing encloses the driver circuit;
• and
• a display surface comprising a plurality of surface mount device (SMD) LED modules arranged as pixels and attached to the first side of the printed circuit board, wherein the pixels are arranged in a rectangular array comprising at least fifty pixels, and wherein
• each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch, the pitch is a predetermined constant number, and the modular LED display panel being configured to be swapped with another modular LED display panel having a pitch different from the pitch of the modular LED display panel while having the same height as the height of the modular LED display panel and the same width as the width of the modular LED display panel.
