Pixel circuit, drive method therefor, display panel, and splicing screen

摘要: The invention provides a pixel circuit, drive method therefor, display panel and splicing screen, belongs to the technical field of display. circuit comprises switching unit anda light emitting diode, wherein diode has first electrode for receiving power voltage, second voltage. responds scanning signal controls illumination state according signal. Compared with driving in an existing panel, used can reduce wires, thereby realizing narrow frame design employing is applied screen realize large-sized high-resolution panel.
