L~ght Apparatus for Vse Nith A Co~pact Computer V~deo Screen
Background ~f the Invention
Compact computer apparatuses having video vlewing screens
are quite popular and typically comprise hand-held, portable,
battery-operated devices which typically display information
or play games employing a video screenl particularly a generally
flat, liquid crystal display (LCD) screen. Such compact video
computer apparatuses may include, but not be limited to:
calculators, computer video games, lap top computers and other
- computers where a variety of software is employed. In particular,
compact video games, such as the compact video game system known
- as GAME BOYTM (a trademark of Nintendo of America, Inc.), is
a completely self-sustained video game system which may be
operated by employing a collection from a library of software
game packs. The Nintendo GAME BOYTM compact video game system
provides a compact, self-contained, battery-operated, portable,
~: hand-held computer with a cross key joy stick to operate the
game and start and select buttons with an LCD-type screen,
together with volume controls 80 as to display and enable the
user to display images and play games.
~`` While video display screens are employed and typically
`; include a flat LCD-type screen, such LCD-type display screens
are often difficult to observe by the user in partial light,
particularly, for example, in semi-darkened rooms, automobiles,
`, planes, trains, buses and the like due to the lack of illumination
on the LCD screen to permit suitable contrast during use.
~i, Therefore, it is desirable to provide a light apparatus
`~ to enhance the view of the video screens of compact video systems,
` 30 particularly video systems employing a flat, LCD-type screen,
such as for example, as illustrated by the Nintendo GAME BOYTM
video game system.

without the need for direct lighting and so positioned to provide
indirect lighting or employing different light bulbs, such as
soft llghts, or employing lights on all or one surfaces to provide
the lighting necessary to enhance the video screen. The light
apparatus includes electrical ~witch means, typically a sliding
switch mean~, to pro~ide off/on power with electrical wiring
from the batteries in the battery compartment through the
electrical switch means and to the light, with the electrical
switch means typlcally comprising a sliding off/on switch which
makes contact with a tengion-bissed metal bar which in the "on"
position forces the metal bar to make contact ~nd to light the
light bulbs and in the "off" position to break the circuit.
- In the light apparatus, the optical light system employed
in combination is of considerable importance in providing view
enhancement of the display screen. The light bulbs are a source
of white light (filaments), the light bulb shields or tabs prevent
concentrated light from illuminating directly the surface of
- the LCD screen, the white or light-colored wall~ about the screen
diffuse the white light from the bulbs and the white finish
~`~ 20 is preferably a flat white rather than a glossy white finish
; to reflect a homogenous light onto the surface of the LCD display
` screen to eliminate uneven illumination of the display screen.~he light apparatus includes an attachment means to
- releasably secure the body of the light apparatus in a releasable
manner to the compact computer apparatus and optionally so as
to permit adjustment of the open viewing ~area of the light
apparatus to be slid or positioned over the video screen of
