The invention provides an energy-saving display and an electric device. The energy-saving display comprises a first display screen, an eye sight detection unit, a first data processing unit and a first display control unit, wherein the first display screen is used for displaying output information; the eye sight detection unit is used for intercepting image information of eye sights and calculating parameters of the eye sights in the image information by a preset algorithm; the first data processing unit is used for calculating a first coordinate of the eye sights in a first area and a second coordinate of the eye sights in a second area in the first display screen at present in accordance with the parameters of the eye sights, wherein the first coordinate and the second coordinate are taken as display control parameters; and the first display control unit is used for generating electric energy-saving signals so as to control the power consumption of the first display screen. According to the embodiment of the invention, a user selects a proper energy-saving way and utilizes an eye sight diction technology sufficiently, so that the display can realize adaptive energy conservation, thus the energy-saving purpose is reached and the experiences of the user for the display are not influenced.
