The present disclosure relates to an automotive glass product comprising a glazing having at least one glass substrate, a first image, and a second image separated in space from the first image, wherein the first image and the second image are at least partially aligned at an angle through the glass product, and wherein the first image and the second image provide a three-dimensional pictograph from at least one viewing angle.

The present disclosure relates to an electronic device, a display device, and a driving method for the display device, and relates to the field of display technology. The display device includes a display panel, a polarization conversion layer, and a lens layer. The display panel is used to display multiple depth-of-field images in a time-division way during a frame. The polarization conversion layer is arranged on the light exit side of the display panel, and is used to convert light for different depth-of-field images into polarized light of different polarization states. The lens layer is arranged on the side of the polarization conversion layer away from the display panel, and includes a plurality of lens units, each lens unit including a metasurface lens.

An apparatus and a method for image display include a projection screen, a projection device, a control unit, and an imaging element. The projection screen is movable back and forth along an axis perpendicular to the projection face under control from the control unit. The control unit is configured to divide an image to be projected into a set of sub-images depending on distances, of one or more objects in the image, to be perceived by a user along the axis, and to control the projection screen and the projection device such that the projection device projects the set of sub-images onto the projection face when the projection face is moving to different positions respectively. The imaging optical element is configured to form a virtual image of the respective sub-image when the projection face is moving to the corresponding position.
