Abstract

A display apparatus includes a panel, a first light source, a second light source, a first light guide plate, a second light guide plate, and a processor. The panel includes a first area for displaying a first data and a second area for displaying a second data. The first light guide plate corresponding to the first area reflects the light provided by the first light source to the first area. The second light guide plate corresponding to the second area reflects the light provided by the second light source to the second area. The processor determines the states of the first light source and the second light source. The first or second light source is not operated all the time so as to conserve the power.
