Abstract
An image projection optical module including: an image generating element configured to generate an image; an image display unit configured to display the image; and a coupling member thermally connected to the image generating element, the coupling member including a front heat dissipation portion on a front portion of the coupling member when a direction of line of sight of a user wearing a casing of a head mounted display provided with the image projection optical module is defined as a forward direction, the front heat dissipation portion being to dissipate heat.
Claims15
An image projection optical module comprising:
- an image generating element configured to generate an image;
- an image display unit configured to display the image;
- and
- a coupling member thermally connected to the image generating element,
- wherein the coupling portion including a front heat dissipation portion on a front portion of the coupling member when a direction of line of sight of a user wearing a casing of a head mounted display provided with the image projection optical module is defined as a forward direction, the front heat dissipation portion being to dissipate heat, and
- wherein the coupling member has an opening in which the image display unit is inserted, and an adiabatic member is provided between the coupling member and the image display unit, the adiabatic member being lower in thermal conductivity than the coupling member.
A head mounted display comprising:
- an image projection optical including an image generating element configured to generate an image;
- an image display unit configured to display the image;
- and
