Abstract: A floating image display device, configured to generate a floating image, is provided. The floating image display device includes an image module and at least one transflective optical element. The image module is configured to provide a first image. The transflective optical element includes a first reflective surface and a second reflective surface. The first image is located between the first reflective surface and the second reflective surface. Each of the first reflective surface and the second reflective surface includes a curved surface and has no opening on an optical axis thereof. The second reflective surface is a transflective surface. The first reflective surface and the second reflective surface are configured to re-converge rays from the first image to form a second image. The second image is a floating image.

Abstract: A switchable floating image display device, including a light-emitting stack layer, a light-emitting pattern stack layer, a transparent barrier layer, an optical imaging module, and a power supply module, is provided. The light-emitting stack layer is configured to generate a first pattern beam. The light-emitting pattern stack layer is configured to generate a second pattern beam. The transparent barrier layer is disposed between the light-emitting stack layer and the light-emitting pattern stack layer. The optical imaging module is configured to enable the first pattern beam to form a first floating image, and enable the second pattern beam to form a second floating image. The power supply module is electrically connected to the light-emitting stack layer and the light-emitting pattern stack layer, and configured determine whether to generate the first or second floating image by switching between the light-emitting stack layer and the light-emitting pattern stack layer to emit light.

Abstract: A light source module including a light guide plate and a light emitting element is provided. The light guide plate includes an upper surface concentric circle structure and a lower surface concentric circle structure opposite to the upper surface concentric circle structure. The center of the upper surface concentric circle structure corresponds to the center of the lower surface concentric circle structure. The light emitting element is disposed corresponding to the center of the upper surface concentric circle structure and the center of the lower surface concentric circle structure.

Abstract: A light field display module including a light field display layer, an adjustment layer, and an image forming layer is provided. The light field display layer is configured to form a light field image beam. The adjustment layer is disposed on a path of the light field image beam, and configured to adjust the light field image beam. The image forming layer is disposed on the path of the light field image beam from the adjustment layer, and configured to change a position of a light field image by changing a direction of the light field image beam. The image forming layer has multiple optical micro-structures.
