NEC Display Solutions is a manufacturer of computer monitors and large-screen public-information displays, and has sold and marketed products under the NEC brand globally for more than twenty years. The company sells display products to the consumer, business, professional , digital signage and medical markets. The company became a wholly owned subsidiary of Japan-based NEC Corporation on March 31, 2005. Prior to that date, the company was known as NEC50 joint venture between NEC Corporation and Mitsubishi Electric that began in 2000, and sold display products under both the NEC and Mitsubishi brands. The company, which is no longer affiliated with Mitsubishi, currently sells and markets products under the NEC brand only. Wikipedia.

A projector in an illumination optical system, the projector comprising:a laser light source (101);a synchronization signal processor (505) that converts synchronization signals that are synchronized with video signals input from outside into video signals to be used inside the projector;an LD driver(506) that controls a lighting state of the laser light source according to the synchronization signals output from the synchronization signal processor;an LED light source (102);an LED driver (507) that controls a lighting state of the LED light source according to the synchronization signals output from the synchronization signal processor;a rotational state detector (510) that detects a rotational state of a phosphor wheel (508); anda phosphor wheel driver (508) that, based on a detected result of the rotational state detector, controls the rotational state of phosphor wheel such that a color of a video signal indicated by one of the synchronization signals output by the synchronization signal processor matches a color output by the illumination optical system that indicates the rotational state of phosphor wheel detected by the rotational state detector.


A data transfer system (1) includes a display device (200) and a portable information terminal (100). The display device (200) includes a first display panel (201) having a first display screen (202) for displaying an image, a terminal detection unit (212) configured to detect that the portable information terminal (100) has approached the first display screen (202), and a first display processing unit (213) configured to cause the first display screen (202) to display a storage location image which is an image indicating information about a storage location of data in another device when the approach of the portable information terminal (100) is detected by the terminal detection unit (212).

A display apparatus includes a sight line detection sensor that detects a sight line of a user; a distance measurement sensor that measures a distance between a display panel and a user; and a control unit that determines a control region set in separate light emitting parts arranged on the display panel, where an amount of light emission is controlled in the control region, based on the sight line detected by the sight line detection sensor and the distance measured by the distance measurement sensor. Typically, the control unit determines the control region in a manner such that the longer the distance measured by the distance measurement sensor, the smaller the control region, and the shorter the distance measured by the distance measurement sensor, the larger the control region.


A signal input switching circuit, including a switch circuit including a plurality of input terminals to which signals are respectively applied as input from different signal sources, and the switch circuit supplying as output thereof a signal that is applied as input by way of an input terminal selected from among the plurality of input terminals, and input control units provided corresponding to each of the plurality of input terminals belonging to the switch circuit, controlling signal sources that are connected to input terminals that were not selected by the switch circuit to not present signals to the corresponding input terminals.

The object of the invention is to provide a projector that, when using a high definition display panel as an image forming means, can use a projection lens having an MTF value less than a predetermined value relative to the spatial frequency of the panel, and that can prevent an increase in the size and cost of the projection lens. The projector of the invention includes a DMD that forms an image, a projection lens that projects the image formed by the DMD on a projected surface, and a display control unit that controls an image forming operation of the DMD. The display control unit forms a frame image by sequentially forming a plurality of images using a combined pixel (303a, 300b) which is configured of a plurality of pixels (302), and with respect to temporally continuous two images, the display control unit forms one image at a position that is shifted by a distance that corresponds to the pixel pitch of the DMD in a predetermined direction relative to the other image.
