    Abstract: Inventive driving circuit and driving method of a display are provided. The driving method includes equally dividing a frame time into N divided portions, where N?1 and N is an integer; setting two switch signals in each of the divided portions of time; and turning the OLED (6) on when a first switch signal switches the first switch tube (1) on and the second switch tube (2) receives the first digital signal, in each of the divided portions of time, and turning the OLED (6) off when the second switch signal switches the first switch tube (1) on and the second switch tube (2) receives the second digital signal. By equally dividing a frame time, a digital signal (0/1) may replace for the conventional analog signal to turn on/off an OLED based on time division.
