Abstract: The present disclosure provides a display device and a control method thereof. The control method of the display device comprises: obtaining, based on the first light output ratio and the second light output ratio, a first luminous flux set composed of values of luminous fluxes output by a combination path at a current bit depth, and a second luminous flux set composed of values of luminous fluxes output by the combination path at a target bit depth respectively; obtaining, based on the first luminous flux set and the second luminous flux set, a value of a luminous flux to be expanded to achieve the target bit depth at the current bit depth; and adjusting a mapping relationship between the value of each luminous flux to be expanded and a value of a maximum luminous flux in the first luminous flux set corresponding to the current bit depth based on a display bit depth of the display device.

Abstract: Provided is a polarization splitting device. The polarization splitting device includes a first optical element. The first optical element comprises a light incident surface, a polarization splitting interface and a reflective interface, and the polarization splitting interface and the reflective interface are correspondingly arranged. Incident light enters the first optical element through the light incident surface, and is split into first light and second light through the polarization splitting interface; the first light is incident on the reflective optical element after being reflected by the reflective interface: and the second light exits from the first optical element after being transmitted through the polarization splitting interface.
