Problems solved by technology

[0002] In the prior art, when the OLED (Organic Light Emitting Diode) display panel performs high-grayscale display or low-grayscale display for a long time, the OLED light source will be in an extreme working state for a long time. At this time, if the OLED display panel If the display screen is switched, the display screen before switching can be seen on the switched display screen, which becomes a ghosting phenomenon and affects the display effect of the OLED display panel

Abstract

The invention provides a pixel driving circuit, a driving method thereof and a display device, wherein the pixel driving circuit, the driving method thereof and the display device belong to the fieldof displaying technology. The pixel driving method is applied to an OLED display panel and comprises the steps after the pixel of the OLED display panel displays current gray scale value preset time and before the pixel is switched from the current gray scale value to a target gray scale value, acquiring a corresponding voltage compensating value in switching the current gray scale value to the target gray scale value; compensating target data voltage which corresponds with the target gray scale value by means of the voltage compensating value, and obtaining an actual voltage value; and inputting the actual voltage value into the pixel. The pixel driving circuit, the driving method thereof and the display device can improve a ghost phenomenon of the OLED display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit, a driving method and a display device. Background technique [0002] In the prior art, when the OLED (Organic Light Emitting Diode) display panel performs high-grayscale display or low-grayscale display for a long time, the OLED light source will be in an extreme working state for a long time. At this time, if the OLED display panel If the display screen is switched, the display screen before switching can be seen on the switched display screen, which becomes an afterimage phenomenon and affects the display effect of the OLED display panel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pixel driving circuit, a driving method and a display device, which can improve the afterimage phenomenon of the OLED display device. [0004] In order to solve the above technical problems, embodi...
