Abstract
An LED display panel structure comprises a PC board, a front plate having a plurality of through-holes defined thereon, a plurality of washers, each of which is provided on a back surface of the front plate in correspondence with each of the through-holes, a plurality of LEDs, each of which is inserted through a central aperture of each of the washers being smaller than a diameter of the LED to be clamped therein, and a plurality of holders, each of which has a first recess and a second recess, each of the holders receives and holds each of the LEDs in its first recess and is attached on the PC board by water resistant adhesive filled in the second recess. A pair of through-bores communicating the first recess with the second recess are defined therebetween to allow a pair of leads of each of the LEDs to extend therethrough and connect to the PC board. Such a structure can prevent moisture from seeping in to damage the LEDs.
