Electronic device

An electronic device, comprising:

• a display panel;
• a light-emitting element layer used for providing a light source to the display panel;
• a touch element layer overlapping the display panel;
• a timing control unit electrically connected to the display panel and used for providing a first synchronization signal;
• a light source driving unit electrically connected to the light-emitting element layer and used for receiving the first synchronization signal;
• and
• a touch processing unit electrically connected to the touch element layer and used for receiving the first synchronization signal,
• wherein the display panel is used for displaying a first frame, and a duration of the first frame comprises a duration of the first synchronization signal, a first duration, and a second duration, wherein within the first duration, the touch processing unit receives a touch signal from the touch element layer, and within the second duration, the light source driving unit has the light-emitting element layer perform scanning, wherein the first duration and the second duration are separated.
