Light emitting diode array structure, and printing head and printing device thereof

摘要

A light emitting diode (LED) array structure includes a substrate and a plurality of light emitting thyristors. The light emitting thyristors are arranged linearly on the substrate. Each light emitting thyristor includes a strip portion and a plate portion connected to each other, and the plate portions of the adjacent light emitting thyristors are staggered with each other, so as to maintain an arrangement density of the light emitting thyristors, and increase a distribution area of the light emitting thyristors. A printing head and a printing device with the foregoing LED array structure are also provided herein, so as to improve photoconductivity and printing speed of the printing device through the light emitting thyristors, which provide a raised light emission amount by increasing the distribution area.
