Abstract
A display device includes a display plate, a micro light source, a first reflecting element and a second reflecting element. The display plate has a pattern. The micro light source emits a light beam. The first reflecting element is arranged beside a first side of the display plate. A first portion of the light beam is reflected by the first reflecting element. A second portion of the light beam is transmitted through the first reflecting element. The second reflecting element is arranged beside a second side of the display plate to reflect the light beam. The light beam is repeatedly reflected by the first reflecting element and the second reflecting element, so that a multiple-luminous effect of the pattern is provided.
Claims11
A display device, comprising:
- a casing;
- a display plate disposed within the casing, and having an unchangeable pattern;
- at least one micro light source disposed within the casing, and arranged near the display plate, wherein the at least one micro light source emits at least one light beam;
- a first reflecting element disposed within the casing, and arranged beside a first side of the display plate, wherein the first reflecting element is made of a translucent material, so that a first portion of the at least one light beam is reflected by the first reflecting element, and a second portion of the at least one light beam is transmitted through the first reflecting element;
- and
- a second reflecting element disposed within the casing, and arranged beside a second side of the display plate to reflect the at least one light beam, wherein the reflectivity of the second reflecting element is 100% so that the at least one light beam is repeatedly reflected by the first reflecting element and the second reflecting element to provide a multiple-luminous effect of the pattern.

A display device, comprising:
- a casing;
- a display plate disposed within the casing, and having an unchangeable pattern;
- at least one micro light source disposed within the casing, wherein the at least one micro light source emits at least one light beam;
- a light guide plate arranged between the display plate and the at least one micro light source, wherein after the at least one light beam is received by the light guide plate, the at least one light beam is guided to the display plate by the light guide plate;
- a first reflecting element disposed within the casing, and arranged beside a first side of the display plate, wherein the first reflecting element is made of a translucent material, so that a first portion of the at least one light beam is reflected by the first reflecting element, and a second portion of the at least one light beam is transmitted through the first reflecting element;
- and
- a second reflecting element disposed within the casing, and arranged beside a second side of the display plate to reflect the at least one light beam, wherein the reflectivity of the second reflecting element is 100% so that the at least one light beam is repeatedly reflected by the first reflecting element and the second reflecting element to provide a multiple-luminous effect of the pattern.

A display device, comprising:
- a casing;
- a display plate disposed within the casing, and having an unchangeable pattern;
- at least one micro light source disposed within the casing, and arranged near the display plate, wherein the at least one micro light source emits at least one light beam;
- a first reflecting element disposed within the casing, and arranged beside a first side of the display plate, wherein the first reflecting element is made of a translucent material, so that a first portion of the at least one light beam is reflected by the first reflecting element, and a second portion of the at least one light beam is transmitted through the first reflecting element;
- and
- a second reflecting element disposed within the casing, and arranged beside a second side of the display plate to reflect the at least one light beam, wherein the reflectivity of the second reflecting element is 100% so that the at least one light beam is repeatedly reflected by the first reflecting element and the second reflecting element to provide a multiple-luminous effect of the pattern;
- wherein the display device further comprising:
- at least one light guide element arranged around the display plate, and located near the display plate, wherein after the at least one light beam is received by the at least one light guide element, the at least one light beam is guided to the display plate by the at least one light guide element, wherein each micro light source is aligned with and arranged beside one corresponding light guide element;
- and
- at least one reflective structure corresponding to the at least one light guide element, wherein each reflective structure is disposed on a surface of the corresponding light guide element, and the at least one light beam is reflected by the at least one reflective structure.
