DISPLAY SYSTEM CAPABLE OF AUTO-ADJUSTING BRIGHTNESS AND METHOD FOR AUTO-ADJUSTING BRIGHTNESS THEREOF
First Claim
1. A display system comprising:
- a display panel;
a solar battery configured for converting light energy into electric current;
an electric current measuring module configured for measuring current from the solar battery;
a memory configured for storing a pre-defined associative array comprising a collection of current values and a collection of corresponding brightness values; and
a brightness adjusting module configured for querying the associative array to get the corresponding brightness value using the electric current value, and adjusting the brightness of the display panel based on said corresponding brightness value.

Abstract
A display system includes a display panel, a solar battery, an electric current measuring module, a memory, and a brightness adjusting module. The solar battery is for converting light energy into electric current. The electric current measuring module is for measuring electric current generated from the solar battery. The memory is for storing a pre-defined associative array of current values and their corresponding brightness values. The brightness adjusting module is for querying the associative array stored in the memory to get the corresponding brightness value, using the measured electric current value as a key, and adjusting the brightness of the display based on the brightness value returned from the associative array.
