Abstract

This technique provides a display device including an optical unit that is located at a lower section of a housing accommodating a display panel. The optical unit has a unit main body that includes a plurality of light guide members integrally provided at a base, and a case accommodating the unit main body. The light guide members of the unit main body include a receiving light guide member that has an incident surface exposed to a front surface of the housing, an emitting surface for emitting light to a light receiving sensor, and a reflective surface provided between the incident surface and the emitting surface, and an emitting light guide member for guiding light from a light emitting diode to the front surface of the housing.

Claims (16)

1 . A display device comprising:

an optical unit located at a lower section of a housing accommodating a display panel, wherein

the optical unit includes a unit main body having a base and a plurality of light guide members provided integrally to the base, and a case accommodating the unit main body, and

the light guide members of the unit main body include a receiving light guide member that has an incident surface exposed from a front surface of the housing, an emitting surface for emitting light to a light receiving sensor, and a reflective surface provided between the incident surface and the emitting surface; and an emitting light guide member for guiding light from a light emitting diode to the front surface of the housing.

2 . The display device according to claim 1 , wherein the case has a reflective surface at a position opposite to the reflective surface of the receiving light guide member.

3 . The display device according to claim 2 , wherein the reflective surface of the case is glossy.

4 . The display device according to claim 2 , wherein the reflective surface of the case is located substantially parallel to the reflective surface of the receiving light guide member.

5 . The display device according to claim 1 , wherein the receiving light guide member includes a light guide member for guiding infrared light from an infrared remote controller and a light guide member for guiding ambient light, and the case has a reflective surface at a position opposite to the reflective surface of the light guide member for guiding infrared light.

6 . A display device comprising:

an optical unit located at a lower section of a housing accommodating a display panel, wherein

the optical unit includes a unit main body having a receiving light guide member that has an incident surface exposed from a front surface of the housing, an emitting surface for emitting light to a light receiving sensor, and a reflective surface provided between the incident surface and the emitting surface; and a case accommodating the unit main body, and

the case has a reflective surface located at a position opposite to the reflective surface of the receiving light guide member.

7 . The display device according to claim 6 , wherein the reflective surface of the case is glossy.

8 . The display device according to claim 6 , wherein the reflective surface of the case is located substantially parallel to the reflective surface of the receiving light guide member.

9 . The display device according to claim 6 , wherein the receiving light guide member includes a receiving light guide member for guiding infrared light from an infrared remote controller and a receiving light guide member for guiding ambient light, and the case has a reflective surface at a position opposite to the reflective surface of the receiving light guide member for guiding infrared light.

10 . The display device according to claim 6 , wherein the unit main body of the optical unit has an emitting light guide member for guiding light from a light emitting diode to the front surface of the housing.
