Problems solved by technology

[0005] However, due to the parasitic capacitance between the gate and the drain of the switching thin film transistor, this will cause the source of the switching thin film transistor to change due to the change of the drain voltage of the switching thin film transistor when the switching thin film transistor is turned from on to off. , thus causing a voltage change at one pole of the storage capacitor storing pixel data, causing the current flowing through the OLED to be unstable, affecting the display effect of the screen and increasing the power consumption of the light emitting diode

Abstract

The invention provides a display panel, a display device and a pixel driving method. In the display panel, each row of sub-pixels is correspondingly connected with at least one voltage switching circuit, each voltage switching circuit comprises a first voltage switching sub-circuit and a second voltage switching sub-circuit, the first voltage switching sub-circuit is configured to control a threshold compensation circuit of the sub-pixel of the corresponding row to work or not to work when a scanning line of the corresponding row controls the threshold compensation circuit of the sub-pixel ofthe corresponding row, responding to the control of the scanning line of the corresponding row, different power supply positive voltages are provided for a power supply positive voltage end of the rowof sub-pixels, and the second voltage switching sub-circuit is configured to provide different power supply negative voltages for a power supply negative voltage end of the row of sub-pixels in response to the control of the scanning line of the corresponding row when the scanning line of the corresponding row controls the threshold compensation circuit of the sub-pixel of the corresponding row to work or not work. Therefore, the display effect of the display panel is effectively improved, and meanwhile it is guaranteed that the power consumption of the display panel is not changed.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of display technologies, and in particular, to a display panel, a display device, and a pixel driving method. Background technique [0002] Organic Light Emitting Diode (OLED for short) display devices have the advantages of low power consumption, high color gamut, high brightness, high resolution, wide viewing angle, and high response speed. OLED display devices can be classified into two categories, passive matrix OLED (PMOLED) and active matrix OLED (AMOLED), according to their driving methods. Among them, AMOLED has pixels arranged in an array, belongs to the active display type, has high luminous efficiency, and is usually used as a high-definition display device. [0003] The AMOLED is a current-driven device. When a current flows through the organic light-emitting diode, the organic light-emitting diode emits light, and the brightness of the light is determined by the current passing thr...
