Abstract: An electro-luminescent display apparatus which is capable of displaying two kinds of images is disclosed. The apparatus has a front and a rear electro-luminescent unit therein, and the green light emitted from the front unit directly displays the real image which looks close to a viewer while the orange light emitted from the rear unit is reflected by a reflector disposed at the back of the apparatus and displays a virtual image which looks far from the viewer. In order to reflect the light emitted backward from the front unit and the light emitted forward from the rear unit, reflecting electrodes are provided on the rear surface of the front unit or a reflecting film is disposed in the space between the front and the rear units.

Abstract: A power system for a display, particularly an electroluminescent display, includes a temperature sensor for sensing the temperature of the glass panel. A first power supply circuit supplies a first power output having a first average power and first peak power. A second power circuit generating a second power output having second average power greater than the first average power and a second peak power less than the first peak power.
