DISPLAY PANEL AND DRIVING METHOD THEREOF

摘要

A display panel includes a control circuit and a pixel structure. The control circuit selectively provides a data signal or a first reference voltage signal. The pixel structure includes a capacitor, a first, a second and a third switch unit. For the first switch unit, a first and a second terminal are coupled to two the capacitor in series, and a control terminal receives a control signal. For the second switch unit, a first terminal is coupled to the second terminal of the first switch unit, and the control terminal receives a first scan signal. For the third switch unit, a first terminal receives the data or first reference voltage signal, a second terminal is coupled to the second terminal of the second switch unit and a light emitting element, and the control terminal is coupled to the second terminal of the first switch unit.
