1. A display apparatus comprising:
a transparent display panel comprising a plurality of pixel devices, wherein each pixel device of the plurality of pixel devices comprises a plurality of sub pixels and an aperture;
a first optical shutter part provided at a first side of the plurality of pixel devices and a second optical shutter part provided at a second side of the plurality of pixel devices opposite from the first side;
a plurality of third optical shutter parts, wherein each third optical shutter part of the plurality of third optical shutter parts corresponds to the aperture of a pixel device of the plurality of pixel devices;
memory storing one or more instructions; and
at least one processor configured to execute the one or more instructions,
wherein the one or more instructions, when executed by the at least one processor individually or collectively, cause the display apparatus to:
control the transparent display panel to alternately display a first image and a second image at a pre-set output frequency,
control the first optical shutter part and the second optical shutter part to be in an open state or a closed state based on the pre-set output frequency,
control the second optical shutter part to be in the closed state while the first optical shutter part is in the open state,
control the second optical shutter part to be in the open state while the first optical shutter part is in the closed state, and
based on at least one of the first optical shutter part and the second optical shutter part being in the open state, control the plurality of third optical shutter parts to be in the closed state.
 
10. A method of controlling a display apparatus, the method comprising:
controlling a transparent display panel of the display apparatus to alternately display a first image and a second image at a pre-set output frequency, wherein the transparent display panel comprises a plurality of pixel devices, and each pixel device of the plurality of pixel devices comprises a plurality of sub pixels and an aperture;
controlling a first optical shutter part of the display apparatus and a second optical shutter part of the display apparatus to be in an open state or a closed state based on the pre-set output frequency, wherein the first optical shutter part is provided at a first side of the plurality of pixel devices, and the second optical shutter part is provided at a second side of the plurality of pixel devices opposite from the first side;
controlling the second optical shutter part to be in the closed state while the first optical shutter part is in the open state;
controlling the second optical shutter part to be in the open state while the first optical shutter part is in the closed state; and
based on at least one of the first optical shutter part and the second optical shutter part being in the open state, controlling a plurality of third optical shutter parts of the display apparatus to be in the closed state,
wherein each third optical shutter part of the plurality of third optical shutter parts corresponds to the aperture of a pixel device of the plurality of pixel devices.
 
15. A non-transitory computer readable medium having instructions stored therein, which when executed by at least one processor cause the at least one processor to execute a method of controlling a display apparatus, the method comprising:
controlling a transparent display panel of the display apparatus to alternately display a first image and a second image at a pre-set output frequency, wherein the transparent display panel comprises a plurality of pixel devices, and each pixel device of the plurality of pixel devices comprises a plurality of sub pixels and an aperture;
controlling a first optical shutter part of the display apparatus and a second optical shutter part of the display apparatus to be in an open state or a closed state based on the pre-set output frequency, wherein the first optical shutter part is provided at a first side of the plurality of pixel devices, and the second optical shutter part is provided at a second side of the plurality of pixel devices opposite from the first side;
controlling the second optical shutter part to be in the closed state while the first optical shutter part is in the open state;
controlling the second optical shutter part to be in the open state while the first optical shutter part is in the closed state; and
based on at least one of the first optical shutter part and the second optical shutter part being in the open state, controlling a plurality of third optical shutter parts of the display apparatus to be in the closed state,
wherein each third optical shutter part of the plurality of third optical shutter parts corresponds to the aperture of a pixel device of the plurality of pixel devices.
