摘要： An image generating module and a floating image generation device are disclosed. The image generating module includes an image generation unit and a floating image generation unit. The floating image generation unit having a light axis is disposed parallelly on one side of the image generation unit and includes a light receiving surface and a light emitting surface disposed opposite to each other. The light receiving surface faces the image generation unit. The image generation unit provided an output light for generating a real image outside the light emitting surface. The absolute value of the radius of curvature of the light receiving surface at a position close to the light axis is smaller than the absolute value of the radius of curvature of the light emitting surface at a position close to the light axis. The floating image generation device includes a light source and the image generating module. The floating image generation unit is disposed parallelly on the opposite side of the image generation unit with respect to the light source. The light emitted by the light source passes through the image generation unit to generate a real image.

摘要： The present invention provides a display cover, which includes a light transmission layer, a window pattern disposed on the light transmitting layer, at least one light source disposed on the light transmission layer or the window pattern, and a light conduction layer disposed on the light transmission layer to cover the window pattern and the at least one light source. The window pattern is designed corresponding to a predetermined pattern, so as to define a light transmission window of the predetermined pattern in the light transmission layer. Moreover, at least one light guide structure is disposed on one side of the light conduction layer facing away from the light transmission layer. The at least one light guide structure is configured to at least partially guide light emitted from the at least one light source to the light transmission window.
