Abstract:
A display module includes a display panel and a reflective optical film. The display panel has a display surface. The reflective optical film is disposed on the display surface of the display panel. The reflective optical film includes a cholesteric liquid crystal layer and a first anti-glare layer. The first anti-glare layer is disposed between the display panel and the cholesteric liquid crystal layer.
Abstract:
An embodiment of the disclosure provides an electronic device including a power supply, an optical to electrical converter and a controller. The power supply outputs a first electric power. The optical to electrical converter receives an infrared light beam and converts the infrared light beam to a second electric power. The controller is coupled to the power supply and the optical to electrical converter. The controller operates in a first mode and a second mode. When the controller operates in the first mode, the controller is activated by the second electric power and after the controller is activated, the controller operates in the second mode and drives the power supply. Then, the controller receives the first electric power and stops receiving the first electric power for operation.
