Display apparatus
[Object] To provide a display apparatus capable of obtaining excellent heat radiation performance of a light source while ensuring positional accuracy of the light source. [Solving Means] A display apparatus according to an embodiment of the present technology includes a light guide portion, a casing, a projection portion, a heat source, and a heat-transfer member. The light guide portion is disposed in front of eyes of a user. The casing is fixed to the light guide portion. The projection portion is housed in the casing and is configured to be capable of projecting an image to the light guide portion. The heat-transfer member includes a first end and a second end, the first end being connected to the heat source, the second end being connected to an inner surface of the casing, and is configured to be deformable.
1. A head mounted display, comprising:
a casing fixed to a light guide portion, wherein
the casing includes a first casing portion and a second casing portion attached to the first casing portion,
the first casing portion comprises an inner side surface of the casing,
the inner side surface of the casing is a user side,
the second casing portion comprises an outer side surface of the casing, and
the first casing portion is removably attached to the second casing portion;
a heat source within the casing, wherein the heat source is supported by the first casing portion; and
a deformable heat-transfer member housed within the casing, wherein the deformable heat-transfer member comprises a first end and a second end, and wherein the first end is connected to the heat source and the second end is connected to an inner surface of the second casing portion.
2. The head mounted display according to claim 1 , wherein the light guide portion is in front of a user's eye.
3. The head mounted display according to claim 1 , further comprising a projection portion housed in the casing, wherein the projection portion is configured to project an image to the light guide portion.
4. The head mounted display according to claim 3 , wherein
the projection portion includes a projection optical portion and an image modulation element, and
the image modulation element is between the heat source and the projection optical portion.
5. The head mounted display according to claim 3 , wherein
the heat source is an image display portion that includes a self-emitting element, and
the projection portion includes a projection optical portion configured to project the image from the image display portion to the light guide portion.
6. The head mounted display according to claim 1 , wherein the deformable heat-transfer member further comprises a sheet-like carbon-based material.
7. The head mounted display according to claim 1 , wherein the deformable heat-transfer member is in a folded state.
8. The head mounted display according to claim 1 , further comprising a detection portion attached to the casing, wherein the detection portion is configured to detect a user input operation.
9. The head mounted display according to claim 1 , further comprising a detection portion that includes a pair of detection elements on the second casing portion, wherein
the second end is between the pair of detection elements, and
the pair of detection elements comprises proximity sensors configured to detect a user input in a contactless manner.
10. The head mounted display according to claim 1 , wherein the heat source is a light source.
