Abstract
The utility model discloses a light-emitting diode (LED) display module which comprises a fixing mounting plate. Printed circuit board (PCB) substrates are arranged on the obverse side of the fixing mounting plate. LED chips are respectively arranged on the obverse sides of the PBC substrates. Each LED chip is provided with a reflective shade in an assembled mode. Each reflective shade is provided with a reflective surface in a parabola curved surface shape. A semitransparent diffuse reflection cover plate is arranged on a light outlet side of each reflective shade. The reflective surface in the parabola curved surface shape can effectively reduce light loss and simultaneously is capable of enabling light rays of the LED chips to be evenly projected out. The semitransparent diffuse reflection cover plate is capable of obviously improving the surface texture of a display screen. Due to the fact that the semitransparent diffuse reflection cover plate is capable of enabling the light rays passing through the semitransparent diffuse reflection cover plate to be reflected in a diffused mode and scattered, staggered light rays can occur in a splicing area between two adjacent reflective shades corresponding to the semitransparent diffuse reflection cover plate. Consequently, the light rays projected out through the semitransparent diffuse reflection cover plate are uniform. And then, occurrences of moire fringes can be effectively restrained, and camera shooting effects or picture recording effects can be greatly improved.
