Abstract
The present application relates to a virtual reality display device and a control method thereof. The method comprises: acquiring time required for three-dimensional scene rendering when three-dimensional scene rendering is performed on a frame of image to be displayed (S11); and selecting a mode of local backlight dimming according to the time required for three-dimensional scene rendering and a predetermined screen refresh rate, wherein the greater the time required for three-dimensional scene rendering, the less the time required for the selected mode of the local backlight dimming (S12).
