The present invention discloses a display device and an operation method thereof. The display device comprises a display module, a solar cell, a voltage transmission unit, a controller and a voltage selection unit, wherein the solar cell is used for outputting electric energy, the voltage transmission unit couples with the solar cell so as to receive the electric energy and outputs a light energy conversion voltage at a maximum power point, the controller couples with the solar cell so as to detect the electric energy and controls the voltage transmission unit for outputting the light energy conversion voltage when the electric energy reaches the maximum power point, the voltage selection unit couples with the voltage transmission unit and receives an external voltage, and the voltage selection unit outputs the greater one between the light energy conversion voltage and the external voltage to the display module when the voltage selection unit receives the light energy conversion voltage and the external voltage.
Description
technical field [0001] The present invention relates to a display device and its operating method, and in particular to a display device configured with solar cells and its operating method. Background technique [0002] With the rising awareness of environmental protection, the concept of energy saving and carbon reduction has gradually attracted people's attention. The development and utilization of green energy (ie renewable energy) has become the focus of active investment in development by countries all over the world. In recent years, as the development of green energy has become more mature, the application of green energy will be more frequent, and it is also trying to combine with green energy at many levels (such as construction and consumer electronics). In green energy, since sunlight is available everywhere and does not pollute the earth like other energy sources (such as petrochemical energy and nuclear energy), solar energy and solar cells that can convert sun...
