Abstract:
A light emitting diode (LED) matrix display panel, comprising:an array of LEDs each having a first electrode and a second electrode; a first metal frame normal to the emitted light from said LEDs for bonding the first electrode of said LED to conduct current and for radiating heat generated in said LEDs, having a plurality of first large air ducts, a second metal frame for mounting said LEDs and bonding the second electrode of said LED to conduct current and for radiating heat generated in said LEDs, having a plurality of second air ducts each corresponding to said first large air ducts; spacers to insulate electrically said first metal frame and said second metal frame, and circulating air in said first larger air ducts and second air duct to propagate air radially along the surfaces of said first metal frame and said second metal frame for air-cooling the LEDs.
