Abstract
A light emission display device according to an aspect of the present invention includes: a light guide member that converts rays of incident light from a back face thereof to produce diffused light and emits the diffused light from the front face; a plurality of point light sources that are arranged at intervals on a side of the back face of the light guide member, in which the light guide member includes a light shield structure that partitions the front face into a plurality of light emission regions each corresponding to at least one point light source of the plurality of point light sources immediately below the front face, such that transmission of the rays of light to an adjacent light emission region is reduced.
Claims20
A light emission display device comprising:
- a light guide member that converts rays of incident light from a first face thereof to produce diffused light and emits the diffused light from a second face thereof on an opposite side to the first face;
- and
- a plurality of point light sources that are arranged at intervals on a side of the first face of the light guide member,
- wherein the light guide member comprises a light shield structure that partitions the second face into a plurality of light emission regions each corresponding to at least one point light source of the plurality of point light sources immediately below the second face, such that transmission of the rays of light from each light emission region to an adjacent light emission region is reduced.
A sound collection device comprising:
- a microphone;
- and
- a light emission display portion that switches between a first display state in which an entirety of a light emission face emits light, and a second display state in which a part of the light emission face emits light, in accordance with a functional status of the microphone.
