Display panel, driving method thereof and display device with the display panel

Abstract

The invention provides a display panel, a driving method thereof and a display device with the display panel. A pixel circuit in the display panel comprises the components of a storage capacitor; a driving transistor; an initializing module which controls a gate scan line of this grade in an initializing time period for supplying an initial voltage for the first end of the storage capacitor; a compensating module; a data write-in module; a reset module which controls for realizing conduction between the gate scan line of this grade with the second end of the storage capacitor in a light emitting time period; and a light emitting control mold. The driving transistor is conducted in the light emitting time period for driving a light emitting element to emit light. The driving transistor is conducted in the light emitting time period for driving the light emitting element to emit light. The display panel, the driving method thereof and the display device with the display panel settles a problem of lighting brightness non-uniformness of the light emitting element caused by threshold voltage offset of the driving transistor and IR voltage drop of a power line. The gate scan line of this grade is used for supplying the initial voltage and a reset voltage. The display panel, the driving method and the display device with the display panel have advantages of effectively utilizing a gate scanning signal of this grade, reducing number of wirings in a pixel space, and facilitating realization of high-resolution display.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] In recent years, conventional display panels have been gradually replaced by portable flat display panels. The organic light-emitting display panel has attracted more attention due to its high brightness, wide viewing angle, good contrast, low power consumption, and high-speed response speed. [0003] However, when AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diode) display panels develop to high resolution, due to the reduction of pixel area, insufficient wiring space has become the biggest problem in the industry, especially in the pixel circuit of thin film transistors. When the number cannot be reduced, reducing the power cord opens up another trend. In addition, due to the impact of the LTPS (Low Temperature Poly-silicon, low temperat...
