Abstract

"ELEMENTO DE DISPLAY COM CAPACITáNCIA REDUZIDA". Um elemento de display, como um modulador interferométrico, compreende um condutor transparente configurado como um primeiro eletrodo e um espelho móvel configurado como um segundo eletrodo. Vantajosamente, o refletor parcial é posicionado entre o condutor transparente e o espelho móvel. Como o condutor transparente serve como eletrodo, o refletor parcial não necessita ser condutivo. Por conseguinte, uma maior gama de materiais pode ser utilizada para o refletor parcial. Além disso, um material isolante transparente, como um dielétrico, pode ser posicionado entre o condutor transparente e o refletor parcial para diminuir uma capacitância do elemento de display sem alterar uma distância de abertura entre o refletor parcial e o espelho móvel. Desse modo, uma capacitância do elemento de display pode ser reduzida sem alterar as características ópticas do elemento de display."DISPLAY ELEMENT WITH REDUCED CAPACITY". A display element, such as an interferometric modulator, comprises a transparent conductor configured as a first electrode and a movable mirror configured as a second electrode. Advantageously, the partial reflector is positioned between the transparent conductor and the movable mirror. Since the transparent conductor serves as the electrode, the partial reflector need not be conductive. Therefore, a wider range of materials can be used for the partial reflector. In addition, a transparent insulating material, such as a dielectric, may be positioned between the transparent conductor and the partial reflector to decrease a capacitance of the display element without changing an opening distance between the partial reflector and the movable mirror. In this way, a capacitance of the display element can be reduced without changing the optical characteristics of the display element.
