Embodiment Construction

[0015] Embodiments of the present invention will be described below with reference to the drawings.

[0016] FIG. 1 is a perspective view showing an information processing device corresponding to an embodiment of the present invention. This information processing device is realized as a battery-operated notebook computer 10 .

[0017] The invention turns on the backlight of the area to display any pre-registered application program in the display unit, and displays other areas in black, so as to reduce energy consumption. In addition, the present invention turns on the backlight of a wider area than the application display area, controls the brightness of the backlight of the application display area, and displays the area other than the application display area in black.

[0018] As shown in FIG. 1 , the computer 10 is composed of a main body 16 and a display unit 11 . A display device composed of an LCD (Liquid Crystal Display) is embedded in the display unit 11 . The dis...

Abstract

According to one embodiment, an information processing apparatus includes a display unit comprising a plurality of light-emitting devices, a light-emitting unit which, if a predetermined area of the display unit is displayed, urges the plurality of light-emitting devices corresponding to the predetermined area and an area wider than the predetermined area to emit light, and a controller urging a display area other than the predetermined area, in a display range in which the light-emitting devices emit light by the light-emitting unit, to be displayed in black.

Description

technical field [0001] The present invention relates to a display control technology of a display unit, and in particular to an information processing device and a display control method, which can uniformly control the brightness of a display area for display. Background technique [0002] Generally, as a technique for saving energy consumption by partial display on a display unit, display is controlled by turning on the corresponding backlight of a portion of the area to be displayed, and turning off the other backlights (see JP-A10-207400 (KOKAI)). [0003] However, according to this technique, a display is performed outside the display area, since the backlight illuminates the area, and the luminance in the periphery of the display area degrades when the area to be illuminated by the backlight is set near the display area. Contents of the invention [0004] An object of the present invention is to provide an information processing apparatus and a display control method...
