Testar obtains patent for MINILED light guide structure and display device

The patent abstract shows that the utility model discloses a MINI An LED light guide structure and a display device include: a substrate and a light guide structure; a plurality of LED lamp beads are arranged on the substrate; the light guide structure is arranged on the light-emitting side of the LED lamp bead; the light guide structure is provided with a light-incoming light source on the side close to the LED lamp bead. A light-emitting surface is provided on the side of the light-guiding structure away from the LED lamp bead; the light-emitting surface is a conical surface to refract and diffuse light; the straight-line distance from any position on the light-emitting surface to the central axis of the light-guiding structure is inversely proportional to the straight-line distance from the position to the substrate. This structure can diffuse the light emitted by the LED lamp beads over a large area, thereby increasing the distance between the LED lamp beads, diluting the shadows between the LED lamp beads, reducing the number of LED lamp beads used, and further reducing the overall heat of the MINI LED light guide structure and increasing its service life.
