Abstract: A multi-screen display apparatus includes a first display screen, a second display screen and a prismatic structure optical element. The display area of the first display screen includes a first main display area, a first and second sub display areas. The display area of the second display screen includes a second main display area, a third and fourth sub display areas. The fourth sub display area is adjacent to the second sub display area. The first main display area displays the first part of the first image frame. The first and fourth sub display areas display the second part of the first image frame adjacent to the first part. The second main display area displays the first part of the second image frame. The second and third sub display areas display the second part of the second image frame adjacent to the first part. A display method is also provided.

Abstract: A multi-screen display device includes a plurality of display screens and a prism structure optical element disposed between two adjacent display screens. The prism structure optical element includes a substrate and a plurality of prism columns. The substrate includes a first region and a second region adjacent to each other, and the lengths of the first and second regions are respectively La and Lb, and La≥Lb. The prism columns include a plurality of first and second prism columns in the first and second regions respectively. Each first prism columns has two interior angles θa1, θa2, a first surface and a second surface. Each second prism columns has two interior angles θb1, θb2, a third surface and a fourth surface. The second and/or fourth surfaces are light absorbing surfaces, or a roughness of the second and fourth surfaces is greater than that of the first and third surfaces.

Abstract: The invention provides a display device including a panel module, a reflection module and a light guide module. The panel module has a display area for displaying an image and a perspective area for displaying a background. The reflection module is disposed at a side of the panel module. A reflective sheet on the reflection module faces the panel module. The shape and position of the reflective sheet correspond to the shape and position of the display area, respectively. The light guide module includes a light guide plate and a light source. The light guide module is disposed between the panel module and the reflection module. The light guide plate has a plurality of optical microstructures, and light emitted by the light source is at least partially directed away from the panel module by the optical microstructures and is transmitted to the reflection module.

Abstract: A light guide plate (LGP) and a light source module are provided. The LGP includes a plate body, first microstructures and second microstructures. The plate body has a first light incident surface, a second light incident surface adjacent to the first light incident surface and a first surface connected thereto. The first microstructures are located on the first surface, and each has a first optical surface facing the first light incident surface. Two sides of each first microstructure respectively have a first edge portion. One of the first edge portions faces and is inclined relative to the second light incident surface, and there is a first included angle between the first edge portion facing the second light incident surface and the first surface. The second microstructures are located on the first surface, and each second microstructure has a second optical surface facing the second light incident surface.
