A projector capable of simultaneous or concurrent projection in different positions in the depth direction. The projector includes a plurality of display sections each of which forms a collimated image light ray, a superimposing optical system that superimposes the image light rays having exited out of the plurality of display sections on one another with the image light rays unfocused, a projection optical system that projects an image corresponding to the image light rays superimposed by the superimposing optical system, and a circuit apparatus that causes the image light rays to exit out of local image source areas set in the plurality of display sections to shift a position where the image light rays are superimposed on one another to a plurality of superimposition positions different from one another along an optical axis.

A projector includes a light exit adjustment mechanism that adjusts (sets) a light exit angle to be used for each of component light fluxes IL that exit from self-luminous devices disposed in a plurality of positions in a light emitter and a circuit apparatus that is a light controller that controls a light exit position and the light exit angle of each of the component light fluxes IL that exit out of the light exit adjustment mechanism in accordance with a projection area PD that is irradiated with the component light fluxes IL having passed through the light exit adjustment mechanism. Under the control of the circuit apparatus, the light exit adjustment mechanism allows the component light fluxes that form image light to exit from a plurality of positions at angles different from each other to perform simultaneous or concurrent projection on the projection area.

A projector includes a power receiving terminal, a light source that emits light based on electric power supplied to the power receiving terminal, a light diffuser that adjusts the degree of diffusion of the light from the light source, a specifying section that alternately specifies one of illumination projection and image projection every time electric power supply to the power receiving terminal is started, and a light diffusion controller that controls the light diffuser so that when the specifying section specifies the illumination projection, the light diffuser diffuses the light from the light source, whereas when the specifying section specifies the image projection, the light diffuser transmits the light without substantially diffusing the light.

Projector and method for controlling the same

A projector includes an electricity reception terminal to which electric power is supplied via an electricity feed terminal, a projection section that includes a light source, a spatial light modulator, an irradiation system, and a projection system and projects light, and a control section that switches a content to another whenever electric power supply to the electricity reception terminal is initiated and causes the projection section to project light carrying an image related to the content selected in the switching operation.

Projector and method for controlling projector with changing content

Projector

A projector includes a projection section adapted to project a projection image on a projection surface including a target part, a detection section adapted to detect a distance from a predetermined position to the target part, and a control section adapted to set an area to be projected on the projection surface other than the target part out of the projection image as a partial area based on the distance thus detected, and change a display state of the projection image so that the partial area set is masked.

Projector and projection image control method

A projector includes a projection section adapted to project light, a human detection section adapted to detect a human existing in a predetermined region, and a mode switching section adapted to switch an operation mode to one of a content mode for projecting light of an image related to a content by the projection section, and an illumination mode for projecting light for illumination by the projection section in accordance with a detection result of the human detection section.

Projector and method of controlling projector

A projector includes a light source, a light modulator having an image formation area to form an image, a projection system that projects the image on a display surface, an enclosure that holds at least the light modulator and the projection system, an inclination detection section that detects the inclination of the enclosure with respect to an axis along the optical axis of the projection system, and an image display control section that forms a reference line on the image formation area, the reference line having a predetermined angle with respect to a horizontal line irrespective of the inclination of the enclosure, and the image display control section changes the inclination of the reference line with respect to the image formation area in accordance with the inclination of the enclosure in such a way that the reference line has the predetermined angle with respect to the horizontal line.

A touch panel includes: a first substrate; a second substrate disposed to face the first substrate; an annular seal material that adheres peripheries of the first substrate and the second substrate to each other so as to set a gap between the first substrate and the second substrate; first seal portions that adhere corner portions of the first substrate and the second substrate through the seal material; and second seal portions that are in connection with the first seal portions and adhere side portions of the first substrate and the second substrate through the seal material. Each of the first seal portions has a thickness which is smaller than each of the second seal portions so that the substrate gap is set to be small.

A conductor pattern having both elongated conductors and a dummy pattern is formed on a substrate. The dummy pattern is formed of dummy conductors. The elongated conductors are typically transparent electrodes. The dummy pattern is so configured that each of the dummy conductors are mutually set apart with a spacing as appropriate in the extending direction (top-and-bottom direction) and in the array direction (right-and-left direction) of the transparent electrodes to prevent any two inspection probes from contacting a single dummy conductor.
