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.

This electronic device includes connector (11) to which an external device is connected via a communication cable, controller (13), and output unit (14). Connector (11) includes at least first and second pins. A predetermined voltage is supplied from the external device to the first pin. Controller (13) includes a communication unit to which a signal is input from the external device via a pin other than the first and second pins of connector (11), and outputs, when the communication unit is in an activated state, a first signal indicating the activated state. Output unit (14) outputs, when the first signal has not been output, a detection signal indicating that a connection has not been established with the external device to the external device via the second pin.

An information processing device includes: an image signal processing unit that processes an image signal representing an image, the image including the region, the image signal processing unit sequentially changing a color to be displayed in the region; an image signal output unit that outputs the image signal to a display device; and a receiver unit that receives, from an input device, a signal that instructs to stop the change of the color. The image signal processing unit stops the change of the color in response to the receiver unit receiving the signal.


A light source device capable of improve energy efficiency is provided. A light source device includes a yellow phosphor that emits yellow fluorescence excited by exciting light, a red laser light source that emits red laser light, a first light combining unit that generates first composite light by combining the emitted yellow fluorescence with the emitted red laser light, a blue laser light source that emits blue laser light, and a second light combining unit that generates second composite light by combining the combined first composite light with the emitted blue laser light.

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.

A display system includes a plurality of display apparatuses. Each of the plurality of display apparatuses includes a display panel that displays an image and a sending and receiving unit that at least receives setting information of one of the plurality of display apparatuses. A first display apparatus that is one of the plurality of display apparatuses further includes a coordinate acquiring unit that acquires a coordinate. A first sending and receiving unit of the first display apparatus receives setting information of a second display apparatus specified by the coordinate from the second display apparatus. A first display panel of the first display apparatus displays a setting image that indicates the setting information.

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.
