Light Guide Module and Display Apparatus

摘要

The present invention relates to a display apparatus capable of mounting a transparent touch screen for presenting flexible and extensible characteristics by providing light by a piezoelectric film. The display apparatus of the present invention includes: the piezoelectric film; a light source unit which is disposed on a side of the piezoelectric film to provide RGB light to the inside of the piezoelectric film; a front electrode which is disposed on the front surface of the piezoelectric film; a rear electrode which corresponds to the front electrode and is disposed on the back of the piezoelectric film; a power supply unit which supplies power to the rear electrode and the front electrode; and a switching element for controlling the on-off of the front electrode and the rear electrode.
