A display unit for use with a computer and a power supply, includes an environmentally-sealed enclosure having a removable cover, and housing a liquid crystal display screen, the removable cover serving as an integral heat sink for the power supply, the power supply being mounted on the internal surface of the cover. Further, a backlighting device backlights the display screen, and a cooling plenum conductively and convectively cools the backlighting device, the backlighting device being mounted directly on a surface of the plenum.
Cette invention concerne une unité de visualisation à cristaux liquides pour ordinateur portatif à bloc d'alimentation intégré. L'objet de l'invention comporte une enveloppe scellée à couvercle amovible qui sert de dissipateur de chaleur intégré du bloc d'alimentation monté sur sa surface intérieure. De plus, l'unité comprend un dispositif d'éclairage à contre-jour de l'écran dont le refroidissement par conduction et convection est assuré par un caisson de refroidissement sur lequel ledit dispositif d'éclairage est directement monté.
