Title (EN) ELECTROPHORETIC DISPLAY DEVICE WITH ANTI-REFLECTIVE NANOPARTICLES
(FR) DISPOSITIF D’AFFICHAGE ÉLECTROPHORÉTIQUE AVEC NANOPARTICULES ANTIREFLET
Abstract:
(EN) Example implementations relate to an electrophoretic display (EPD) device with anti-reflective nanoparticles. For example, a display device may include a display panel to display content and an EPD device adjacent to the display panel. The EPD device provides a voltage to at least a portion of the EPD device such that positively-charged anti-reflective nanoparticles in the EPD device are moved toward a negative voltage and negatively-charged anti-reflective nanoparticles in the EPD device are moved toward a positive voltage. The content is displayed based on locations of the positively-charged anti-reflective nanoparticles and the negatively-charged anti-reflective nanoparticles in response to the voltage.
(FR) Des modes de réalisation exemplaires de l’invention concernent un dispositif d’affichage électrophorétique (EPD) avec des nanoparticules antireflet. Par exemple, un dispositif d’affichage peut comprendre un panneau d’affichage pour afficher du contenu et un dispositif EPD adjacent au panneau d’affichage. Le dispositif EPD fournit une tension à au moins une partie du dispositif EPD de sorte que des nanoparticules antireflet positivement chargées dans le dispositif EPD soient déplacées vers une tension négative et des nanoparticules antireflet négativement chargées dans le dispositif EPD soient déplacées vers une tension positive. Le contenu est affiché sur la base des emplacements des nanoparticules antireflet positivement chargées et des nanoparticules antireflet négativement chargées en réponse à la tension.
