The displayer comprises a pixel driving circuit which comprises a first switch element, a second switch element, a third switch element and a fourth switch element, the first switch element has a first end, a second end coupled to a first node and a light-emitting element, and a control end coupled to a second node, the second switch element has a first end coupled to a first signal source, a second end coupled to the first end of the first switch element, and a control end coupled to a first scanning signal line, the third switch element has a first end coupled to a second signal source, a second end coupled to the second node, and a control end coupled to a second scanning signal line, and the fourth switch element has a first end coupled to a third node, a second end coupled to a grounding end, and a control end coupled to the second scanning signal line.

Description

technical field [0001] The invention relates to a display, in particular to a pixel driving circuit. Background technique [0002] A liquid crystal display (liquid crystal display, LCD) includes a first substrate, a second substrate facing the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The first substrate includes two phase-isolated first pixel electrodes and second pixel electrodes on the same plane. A first pixel voltage is applied to the first pixel electrode, and a second pixel voltage equal to the first pixel voltage is applied to the second electrode, so that an electric field is generated between the first pixel electrode and the second pixel electrode, so that Drive the liquid crystal molecules. [0003] The first pixel voltage and the second pixel voltage are usually generated by the first data voltage and the second data voltage, however, the first data voltage and the second data voltage have certai...
