Abstract: A display device includes a display module emitting collimated light along a propagation direction and an adjustment panel disposed on the display module. The adjustment panel includes a first substrate, a second substrate, a medium layer disposed between the first substrate and the second substrate, a first electrode layer disposed on the first substrate, and a second electrode layer disposed on the second substrate and facing the first electrode layer. The medium layer includes a first medium. When the adjustment panel is in a first enabled state, a voltage difference exists between the first substrate and the second substrate to form an electric field distribution. At least one equivalent dioptric structure is formed in the medium layer according to the electric field distribution. At least part of the collimated light passes through the equivalent dioptric structure and emits along a predetermined light emitting direction deflected from the propagation direction.

Abstract: A backlight module includes a plurality of light emitting elements and a plurality of lens structures. Each light emitting element has a light emitting surface. The plurality of lens structures covers each light emitting element. Each lens structure has a light exit surface having a curved shape. The light exit surface has a vertex and a focal point located between the vertex and the light emitting element. The distance between the focal points of two adjacent lens structures is a first distance, and each light emitting element has a light emitting width. The ratio of the first distance to the light emitting width is greater than or equal to 10.

Abstract: A display module includes a backlight module, a liquid crystal layer disposed on the backlight module, and a first light-expanding layer disposed on the liquid crystal layer. The backlight module provides a surface light source. The surface light source forms an image light through the liquid crystal layer, and the first light-expanding layer increases the viewing angle range of the image light along a first direction. The first light-expanding layer substantially extends along a virtual plane, the first direction is perpendicular to the normal of the virtual plane, and a second direction is perpendicular to the first direction and the normal of the virtual plane. The light intensity at the 60-degree viewing angle of the surface light source along the first direction is lower than the light intensity at the 60-degree viewing angle of the surface light source along the second direction.

Abstract: A backlight module includes a supporting plate, a light source module, and an optical modulation film. The light source module includes a plurality of light sources disposed on a supporting surface of the supporting plate. The optical modulation film is disposed above the light source module and has a plurality of light emitting holes. Light from the light source module is distributed by the optical modulation film and emitted via light emitting holes at different positions. The optical modulation film has a periphery area and a central area. An average perpendicular distance between the periphery area and the supporting surface is different from an average perpendicular distance between the central area and the supporting surface.
