The invention relates to an inflated radial truck tire. The existing inflated tire, in particular to the inflated radial truck tire, has the step abrasion phenomenon on the end of the strip pattern which is positioned at two ends of the driving surface, and greatly reduces the service life of the tire. The invention places a ring-shaped disk groove with the appropriate shape and position at the tire shoulder, which is continuously positioned along the circumference of the tire and extended toward the inner direction of radial direction, for decreasing the ground contact pressure of the end of the tire shoulder, thereby inhibiting the occurrence of the step abrasion of the tire shoulder and eliminating the bad phenomenon of seizing stones. In addition, a specified arc shape is designed on the bottom of the ring-shaped disk groove, even if the tire shoulder suffers the strong lateral force and consequently the repeated distorsion is generated, the groove bottom can not generate the tearing failure.

The application provides a backlight module, a manufacturing method thereof and a display device. The backlight module comprises a substrate and a plurality of LED chip structures arrayed on the substrate. Each LED chip structure includes first and second LED chip structures stacked, and a reflecting layer between the first and second LED chip structures, the reflecting layer reflects light, opposite to the surface of the substrate and emitted by the first LED chip structure between the substrate and the second LED chip structure, and the light exits from the side of the first LED chip structure. On one hand, the reflecting layers compensate lateral emission quantity of the light from the front of the first LED chip structures; on the other hand, the added LED chip structures help increaselateral emission quantity of the LED chip structures at the premise that the light emitted from the front of the LED chip structures has unchanged brightness. Both the two aspects weaken the starry effect and even thoroughly eliminate the starry effect.
