Title
(EN) INFORMATION HANDLING SYSTEM MULTIPLE DISPLAY VIEWING ANGLE BRIGHTNESS ADJUSTMENT
(FR) RÉGLAGE DE LUMINOSITÉ D'ANGLE DE VISUALISATION D'AFFICHAGES MULTIPLES DE SYSTÈME DE TRAITEMENT D'INFORMATIONS
Abstract
(EN)
A portable information handling system presents visual images at first and second displays integrated in first and second rotationally-coupled housing portions. When the housing portions rotate to a clamshell configuration, a refractive layer in a "DO" display aligns light illuminated from the display off an orthogonal angle and towards a user while a "SEE" display aligns light illuminated from the display along an orthogonal angle.
(FR)
L'invention concerne un système de traitement d'informations portable qui présente des images visuelles au niveau de premier et second affichages intégrés dans des première et seconde parties de boîtier couplées en rotation. Lorsque les parties de boîtier tournent vers une configuration de coque, une couche de réfraction dans un affichage "DO" aligne la lumière éclairée à partir de l'affichage à un angle orthogonal et vers un utilisateur tandis qu'un affichage "SEE" aligne la lumière éclairée à partir de l'affichage le long d'un angle orthogonal.
