Abstract

The invention discloses a display device, which comprises a photovoltaic cell, a dichroic reflector adjacent to the photovoltaic cell, and a low-refractive index layer adjacent to the dichroic reflector. The low refractive index layer may have a refractive index of about 1.1 to about 1.4.

Description

technical field [0001] The present disclosure relates to electronic display devices that can be self-powered by photovoltaic cells. Background technique [0002] Electronic display devices, such as electronic readers, including electronic paper displays, are used by a large number of users for a variety of applications. These devices are typically powered by rechargeable batteries such as Li-ion batteries. Battery life is very important to users. Short battery life may be detrimental to the commercial viability of any product including such devices. [0003] Solar cells or solar panels are photovoltaic devices that can represent a supplemental or alternative energy source for electronic display devices. Some electronic display devices may have sufficiently low power requirements and may have sufficiently large available surface area such that they can be powered entirely by one or more solar cells, especially when used in light conditions.
