Abstract:
1. A display apparatus, comprising: a backlight module, comprising a plurality of sets of light emitting devices, wherein each set of light emitting devices comprises at least one first color light emitting device and at least one second color light emitting device, primary wavelength ranges of light emitted by the first color light emitting devices in different sets of light emitting devices are different from each other, and primary wavelength ranges of light emitted by the second color light emitting devices in different sets of light emitting devices are different from each other; a filtering module, disposed on a transmission path of light emitted by the plurality of sets of light emitting devices and comprising a plurality of sets of filtering units, wherein each set of filtering units comprises a plurality of filtering units, and each set of filtering units is configured to allow light emitted by one set of light emitting devices in the plurality of sets of light emitting devices to pass through and block light emitted by another set of light emitting devices; and a display panel, disposed on the transmission path of the light emitted by the plurality of sets of light emitting devices, wherein the backlight module turns on the plurality of sets of light emitting devices by turns, and the display panel displays an image corresponding to the set of light emitting devices being turned on in each sub-frame time of each frame time.
