Viewing angle switchable display module
A viewing angle switchable display module includes an organic light-emitting display (OLED) panel, a viewing angle switchable device disposed on the OLED panel, and a quarter wave plate disposed between the OLED panel and the viewing angle switchable device. The viewing angle switchable device includes an absorptive polarizer, a reflective polarizer, and an electrically controlled viewing angle switching element. A transmission axis of the reflective polarizer is parallel to a transmission axis of the absorptive polarizer. The electrically controlled viewing angle switching element is disposed between the absorptive polarizer and the reflective polarizer and includes two conductive layers and a liquid crystal layer including liquid crystal molecules. When there is a potential difference between the two conductive layers, an orthogonal projection of an optical axis of each of the liquid crystal molecules on the absorptive polarizer is parallel to or perpendicular to the transmission axis of the absorptive polarizer.
