| Summary: | A display apparatus having an alterable penetrative index and reflective index and a method of same includes a primary display device and a back light module. A secondary display device is interposed between the primary display device and the back light module to function as a reflective plate. When the external light source is strong, the secondary display device directly reflects the light to the primary display device and the back light module is turned off to save electric power. When the external light source is weak, the reflective index of the secondary display device is adjusted to the minimum so that light provided by the back light module projects directly to the primary display device to achieve optimal utilization. |
