Display apparatus

A display apparatus, adapted to display on at least one of a first display surface and a second display surface, the display apparatus comprising:

• a display panel, provided with the first display surface, and adapted to emit an image beam;
• an optical path selection module, disposed on a transmission path of the image beam from the display panel, and comprising:
• a beam splitting element, adapted to allow a part of the image beam to penetrate and reflect another part of the image beam;
• a first filter element, disposed on the transmission path of the part of the image beam penetrating the beam splitting element;
• and
• a second filter element, disposed on the transmission path of the another part of the image beam reflected by the beam splitting element, wherein the image beam transmitted along a first optical path after passing through the optical path selection module is adapted to present a first image on the first display surface, the image beam transmitted along a second optical path after passing through the optical path selection module is adapted to present a second image on the second display surface, and the first image is different from the second image;
• and
• at least one reflective element, disposed on the second optical path, wherein in response to the image beam having a first color, the part of the image beam is adapted to penetrate the first filter element and be transmitted along the first optical path, and the another part of the image beam is adapted to be blocked by the second filter element and is not transmitted along the second optical path, and in response to the image beam having a second color, the part of the image beam is adapted to be blocked by the first filter element and is not transmitted along the first optical path, and the another part of the image beam is adapted to penetrate the second filter element and be transmitted along the second optical path, and the first color is different from the second color.
