摘要: A display device, a virtual reality equipment, and a driving method are disclosed. The driving method is configured to drive a display device, and the display device (1) includes a display array (10) and a light valve array (20). The display array (10) includes rows of sub-pixels, the light valve array (20) includes a plurality of sub light valves, each of the plurality of sub light valves corresponds to at least one row of sub-pixels, and the light valve array (20) is on a light-emitting side of the display array (10). The driving method includes: allowing a sub light valve to be in a light-shielding state in a case where any sub-pixel in the at least one row of sub-pixels corresponding to the sub light valve is in a response phase of a display operation. The driving method can avoid the smear phenomenon during the display process and improve the display quality of the display device.
