Backlight and light uniformity technology are two key technologies for backlight module design of LCD. On the basis of discussing the advantages and disadvantages of the Intercalated LED traffic signs, backlight and light uniformity technology are creatively applied to the active light-emitting traffic signs in this paper. The novel traffic signs overcome the shortcomings of Intercalated LED traffic signs which follow solar road traffic signs (GA/T 580-2005), make the light-emitting mode of active light-emitting traffic signs upgrade from point emitting to surface emitting, so as to make the large guide signs to realize active light-emitting.
