Detailed ways

Referring to FIG. 1 , an electronic device 100 includes a housing 10 and a display screen 20 . The casing 10 includes a bottom 11 and side walls 12 located on two sides of the bottom 11 . The display screen 20 is located in the space defined by the bottom 11 and the two side walls 12 . The electronic device 100 also includes a solar receiving panel 30 and a light splitting element 40 . The solar receiving plate 30 is disposed on the side wall 12 for receiving solar energy, and the received solar energy is converted into electrical energy by a photoelectric conversion element (not shown) disposed in the casing 10 .

The light splitting element 40 is disposed above the display screen 20 , and the size and thickness of the light splitting element 40 can be set corresponding to the display screen 20 , so that the light splitting element 40 can just cover the display screen 20 . The light splitting element 40 is made of transparent glass, and includes a slope 41 inclined relative to the display screen 20 . The inclined surface 41 is coated with a coating, and the coating can reflect part of the light incident on the inclined surface 41 , while the rest of the incident light passes through the light splitting element 40 and irradiates the display screen 20 .

In this embodiment, the display screen 20 is a reflective display device, such as an electrophoretic electronic paper, a cholesteric liquid crystal display, and the like. The light passing through the light splitting element 40 can be used as the light source required by the reflective display screen 20 . When needed, more light can be transmitted through the light splitting element 40 or reflected onto the solar receiving panel 30 by changing the inclination of the slope 41 relative to the display screen.

In this embodiment, the electronic device 100 further includes a transparent protective plate 50 disposed between the two side walls 12 of the casing 10, and a protective film is provided on the protective plate 50, and the protective film is used to prevent Scratches, etc. are generated on the 50.

Referring to FIG. 2 , in another embodiment, the electronic device 100a is an electronic book device, which includes a reflective display screen, and on the basis of the electronic device 100, an illuminating element 60 is added, and the illuminating element 60 is arranged on the casing 10 On the side wall 12 of the solar panel, it is roughly juxtaposed with the solar receiving panel 30 . After the light emitted by the illuminating element 60 is incident on the light splitting element 40 , part of the light passes through the light splitting element 40 and illuminates the display screen 20 . In this way, when the ambient light outside is weak, the illuminating element 60 can be used as a light source so that the reflective display screen 20 can work normally. In this embodiment, the lighting element is a light emitting diode.
