Abstract
A light path control device includes a substrate, a viewing angle control member including light-shielding patterns patterned on the substrate at regular intervals, and a lens assembly that is formed on the viewing angle control member and includes a plurality of lenses, wherein the light-shielding patterns include electrochromic elements to implement a light-shielding mode or a light-transmitting mode, and a display device including the light path control device.
Claims19
A light path control device, comprising:
- a substrate including a central area and an edge area adjacent to the central area;
- a viewing angle control member including light-shielding patterns patterned on the substrate at regular intervals and substantially arranged in the central area;
- and
- a lens assembly that is formed on the viewing angle control member and includes a plurality of lenses,
- wherein the light-shielding patterns include electrochromic elements to implement a light-shielding mode or a light-transmitting mode, the electrochromic elements comprise a plurality of electrode patterns spaced apart from each other,
- wherein the substrate has a plurality of sides,
- wherein the electrode patterns are connected to each other in the edge area adjacent to at least one first side of the plurality of sides, and
- wherein a first distance between the central area and the at least one first side is greater than a second distance between the central area and at least one second side, different from the at least one first side, of the plurality of sides.

A display device, comprising:
- a display panel that displays an image through a display area in which pixels are arranged and non-display area surrounding the display area;
- and
- a light path control device that is controlled to operate in a light-transmitting mode or a light-shielding mode in response to a share mode or private mode of the display panel,
- wherein the light path control device comprises:
- a substrate;
- a viewing angle control member including light-shielding patterns patterned on the substrate at regular intervals;
- and
- a lens assembly that is formed on the viewing angle control member and includes a plurality of lenses,
- wherein the light-shielding patterns include electrochromic elements to implement a light-shielding mode or a light-transmitting mode, the electrochromic elements comprise a plurality of electrode patterns spaced apart from each other,
- wherein the substrate has a plurality of sides,
- wherein the electrode patterns are connected to each other in the non-display area adjacent to at least one first side of the plurality of sides, and
- wherein a first distance between the display area and the at least one first side is greater than a second distance between the display area and at least one second side, different from the at least one first side, of the plurality of sides.
