Abstract

According to an aspect, a display device includes: a display unit; a light source device that irradiates the display unit with light, and that includes a plurality of luminous bodies; at least one power reception unit that receives power for the light source device; and at least one power transmission unit that wirelessly transmits power to the power reception unit.

Claims (38)

1. A display device comprising:

a display unit;

a light source device that irradiates the display unit with light;

at least one power reception unit that receives power for the light source device;

at least one power transmission unit that wirelessly transmits power to the at least one power reception unit;

a housing that houses the light source device and the display unit; and

a power supply substrate that is disposed outside the housing and on which the at least one power transmission unit is mounted, wherein

the light source device includes a plurality of luminous bodies to which power is supplied from one power reception unit,

the light source device includes a light guide body, a front cover and a back cover interposing the light guide body therebetween, and a light source mounting substrate on which the luminous bodies are mounted,

the back cover includes a light source holding unit disposed on a side surface of the back cover,

the front cover is made of a resin, and includes a side surface cover portion disposed along an outside surface of the light source holding unit,

the light source mounting substrate and the at least one power reception unit are positioned closer to the light guide body side than the front cover,

the at least one power reception unit is inserted into a first penetrating portion that penetrates a part of the back cover, and

the at least one power reception unit faces the at least one power transmission unit with the resin front cover interposed therebetween, and the side surface cover portion covers the first penetrating portion.

2. The display device according to claim 1 ,

wherein the light source device and the power supply substrate are not coupled to each other on a flexible substrate.

3. The display device according to claim 1 ,

wherein each of the luminous bodies emits light in an amount of luminescence according to transmission power transmitted from the at least one power transmission unit.

4. The display device according to claim 1 , further comprising:

a shield portion that surrounds the at least one power reception unit.

5. The display device according to claim 1 ,

wherein the luminous bodies include at least a luminous body of a first color, a luminous body of a second color, and a luminous body of a third color, and are driven by a field sequential method.

6. A display device comprising:

a display unit;

a light source device that irradiates the display unit with light;

at least one power reception unit that receives power for the light source device;

at least one power transmission unit that wirelessly transmits power to the at least one power reception unit;

a housing that houses the light source device and the display unit; and

a power supply substrate that is disposed outside the housing and on which the power transmission unit is mounted, wherein

the light source device includes a plurality of luminous bodies to which power is supplied from the respective power reception units on a one-on-one basis,

the light source device includes a light guide body, a front cover and a back cover interposing the light guide body therebetween, and a light source mounting substrate on which the luminous bodies are mounted,

the back cover includes a light source holding unit disposed on a side surface of the back cover,

the front cover is made of a resin, and includes a side surface cover portion disposed along an outside surface of the light source holding unit,

the light source mounting substrate and the at least one power reception unit are positioned closer to the light guide body side than the front cover,

the at least one power reception unit is inserted into a first penetrating portion that penetrates a part of the back cover, and

the at least one power reception unit faces the at least one power transmission unit with the resin front cover interposed therebetween.

7. The display device according to claim 6 ,

wherein the light source device and the power supply substrate are not coupled to each other on a flexible substrate.
