Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0016] FIG. 1 is a schematic diagram showing an example of a computer as an information processing apparatus related to a first embodiment of the present invention. Of course, the information processing device may be any other device including, but not limited to, a mobile phone, personal digital assistant or similar device.

[0017] The computer 10 includes a computer main body 12 and a display unit 14 . An LCD 16 as a display panel and a privacy filter 17 are incorporated in the display unit 14 .

[0018] The computer 10 may output video signals to the external display 200 to display video images thereon.

[0019] As shown in FIG. 2 , the privacy filter 17 is a viewing angle control filter installed on the image display surface of the LCD 16 . A privacy filter may be installed on the surface of the LCD 16 on the opposite side of the image display surface. The comp...

Abstract

According to one embodiment, an information processing device includes a display panel, a viewing angle control filter configured to control a viewing angle, a connector to which an external display is connectable, and an inhibit unit configured to inhibit to output a video signal via the connector when the viewing angle control filter is driven.

Description

technical field [0001] Embodiments of the present invention relate to an information processing device and a method for controlling a viewing angle and outputting a video signal to an external display. Background technique [0002] In recent years, liquid crystal display devices have been widely used as displays for notebook computers, monitors, or the like. Improvements in viewing angle dependence of liquid crystal displays have been advanced, and viewing angles at the same level as CRTs have also been achieved for liquid crystal display devices. [0003] However, for a display device, allowing a user to view displayed items from the front and making the display device difficult to view from an obliquely front direction is an important aspect mainly for the use of a mobile terminal or the like. This is because, when a confidential document or the like is prepared or read in a public place or the like, the display device should prevent people...
