Abstract: The present invention provides a liquid crystal display integrated with a solar cell module, which includes a first transparent substrate, a second transparent substrate, a cholesteric liquid crystal layer, a third transparent substrate, and a photoelectric conversion layer. The second transparent substrate is disposed on a side of the first transparent substrate, and the cholesteric liquid crystal layer is disposed between the first transparent substrate and the second transparent substrate. The third transparent substrate is disposed on the other side of the first transparent substrate opposite to the second transparent substrate, and the photoelectric conversion layer is adhered between the first transparent substrate and the third transparent substrate. The first transparent substrate, the photoelectric conversion layer and the third transparent substrate constitute the solar cell module.

Abstract: An electronic device including a display unit and a photoelectric conversion board is provided. The display unit includes a display surface and a back surface which are opposite to each other, and an edge of the photoelectric conversion board is rotatably connected to the back surface of the display unit. The photoelectric conversion board includes a substrate, a first photoelectric conversion unit, and a second photoelectric conversion unit. The substrate has a first surface and a second surface which are opposite to each other, the first photoelectric conversion unit is disposed on the first surface, the second photoelectric conversion unit is disposed on the second surface, and an absorption band of the first photoelectric conversion unit is different from an absorption band of the second photoelectric conversion unit.

Abstract: A power source circuit includes a power source detection unit, a control unit and a switch unit. The power source detection unit detects whether a plurality of power sources including a green power source is supplied to the power source circuit, and detects and outputting a power value of the green power source. In addition, the control unit is electrically coupled to the power source detection unit and a load, and the control unit further detects a power consumption value of the load, to generate a switch signal to the switch unit according to the power consumption value of the load and a result detected by the power source detection unit. Therefore, the switch unit selects the green power source and at least one of other power sources thereof to supply electric power to the load when necessary.

Abstract: A method is designed to adjust the distance between the central axes of two ocular lenses of an optical instrument. The method involves the use of a link mechanism to actuate two movable prisms and the two ocular lenses of the optical instrument to move respectively along a base surface such that the optical axes of effective diameters of the two movable prisms are coaxial with the optical axes of the corresponding ocular lenses.
