Claim Text:
1. A display apparatus, comprising: a display module, displaying image content and providing a charging light, wherein energy of the charging light varies in response to light transparency or light reflectivity of the display module adjusted by shifting the image content thereof; a solar cell module, disposed at one side of the display module to receive the charging light and proceed to charge, wherein efficiency of charging for the solar cell module is in response to the energy of the charging light; and a detection unit, disposed on the display module or on the solar cell module, detecting one of a system state of the display apparatus and an intensity of an ambient light, wherein the display apparatus is in a high efficiency charging mode when the display apparatus is in a low power state or a standby state, or when the intensity of the ambient light is low, and when one of the system state of the display apparatus and the intensity of the ambient light meets at least one of the conditions of getting into high efficiency charging mode, outputting a high efficiency image control signal, and the display module displays high efficiency image content according to the high efficiency image control signal, so as to enhance efficiency of charging for the solar cell module.
