An active optical device and a display apparatus including the same are provided. The active optical device includes: first to third electrodes that are sequentially disposed spaced apart from one another; a first refractive index change layer disposed between the first electrode and the second electrode and in which a refractive index is changed by an electric field; and a second refractive index change layer disposed between the second electrode and the third electrode and in which a refractive index is changed by an electric field.
摘要:
An active optical device is provided. The active optical device includes an optically variable layer having a refractive index which changes according to temperature; and a temperature control unit that controls a temperature of one or more regions of the optically variable layer.
摘要:
A flexible display apparatus includes: a flexible display unit; a sensor unit which detects an amount of bending of the flexible display unit; a power supply unit which supplies operating power to the flexible display unit; and a control unit which controls the power supply unit to stop supply of the operating power to the flexible display unit depending on the detected degree of bending of the flexible display unit. With this configuration, the flexible display apparatus is capable of decreasing power consumption and increasing user's convenience by stopping supply of operating power to a flexible display unit based on a degree of bending of the flexible display unit, without requiring a separate switch manipulation or input from a user.
