20120242714 | DISPLAY DEVICE AND PROJECTOR - Since green is expressed by the first sub-pixels and the second sub-pixels, and at the same time, red is expressed by the third sub-pixels using the yellow illumination light, and green is expressed by the first sub-pixels and the second sub-pixels, and at the same time, blue is expressed by the third sub-pixels using the cyan illumination light, the display device can assure the apparent resolution and the brightness using the first and second sub-pixels with greenish color. It should be noted that red and blue can be expressed by the third sub-pixels with magenta color. | 09-27-2012 |
20140022514 | PROJECTOR AND METHOD FOR CONTROLLING PROJECTOR - A projector including a first light source, a second light source that emits light having a color different from the first light source, a light modulator that modulates the light emitted from each of the first and the second light sources, and a controller that controls a first operation state in which the first and the second light sources are driven based on time division driving to perform image display and a second operation state in which the first and the second light sources are driven based on time division driving to perform illumination, wherein in the second operation state, a switching frequency at which the first and the second light sources are switched from one to the other is higher than a switching frequency at which the first and the second light sources are switched from one to the other in the first operation state. | 01-23-2014 |
20140022515 | PROJECTOR - A projector includes a light source; a spatial light modulation device which modulates light from the light source according to an image that is written; a light diffusion device which adjusts a degree of diffusion of the light incident on the spatial light modulation device or the light emitted from the spatial light modulation device; and a light diffusion controller which controls the light diffusion device so that the light diffusion device diffuses the light when the light source starts to light up. | 01-23-2014 |
20140036164 | PROJECTOR - Two light modulators, a first light modulator and a second light modulator, suffice for four light sources, a first light source, a second light source, a third light source, and a fourth light source, whereby the cost can be lowered as compared with a configuration in which three light modulators are required. As a result, cost reduction is achieved. Further, since two light modulators suffice, the size of the projector can be reduced as compared with the configuration in which three light modulators are required. | 02-06-2014 |
20140139811 | PROJECTOR AND METHOD FOR CONTROLLING THE SAME - 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. | 05-22-2014 |
20150022788 | PROJECTOR AND METHOD OF CONTROLLING PROJECTOR - 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. | 01-22-2015 |
