Electronic device

An electronic device, comprising:

• a display panel;
• an optical structure layer disposed on the display panel;
• a driving unit electrically connected to the display panel;
• a timing control unit electrically connected to the driving unit;
• and
• a light sensing unit electrically connected to the timing control unit for providing a light sensing result to the timing control unit,
• wherein the timing control unit is used to receive a first signal, and provides a second signal and a third signal to the driving unit according to the light sensing result, and the driving unit drives the display panel according to the second signal and the third signal, wherein the second signal includes an image signal regulated from the first signal by the timing control unit;
• wherein the timing control unit selects one gamma conversion data from a plurality of gamma conversion data based on the light sensing result;
• wherein the second signal is converted from the first signal based on the gamma conversion data;
• wherein the first signal includes an image signal of the display panel, wherein gray-scale values of at least some pixels in an image presented by the second signal are different from gray-scale values of corresponding pixels in an image presented by the first signal;
• wherein the third signal includes a clock signal or a synchronization signal.
