Abstract
The application discloses a display device and a driving method thereof. The display device comprises a lamp bead and a micro-rotating device. The micro-rotating device is arranged on the light-emitting surface of the lamp bead. The micro-rotating device comprises a rotating plane, and the rotating plane comprises a first area and a second area with different transmittances. When the first area of the rotating plane rotates to the top of the lamp bead, the display device displays with a first gray scale brightness. When the second area of the rotating plane rotates to the top of the lamp bead, the display device displays with a second gray scale brightness. The micro-rotating structure with the first area and the second area with different transmittances is arranged on the light-emitting surface of the lamp bead. The brightness adjustment is realized by using the physical structure of the micro-rotating device, and the brightness adjustment is realized without the control of the gray scale voltage by the chip, so that the chip cost is reduced, and the inaccurate brightness adjustment caused by the voltage loss is avoided.
