Compensation method and compensation device of display panel

Abstract

The invention discloses a compensation method and a compensation device of a display panel. The compensation method of the display panel comprises the following steps: acquiring a current display picture of the display panel; updating the compensation data of the display panel according to the current display picture and the target pixel value; and compensating the display panel according to the updated compensation data. The compensation data of the display panel is updated according to the current display picture and the target pixel value, so the updated compensation data can compensate theproblem of non-uniform light-emitting brightness caused by the aging phenomenon in the use process of the display panel, and the display panel can be compensated when the aging phenomenon occurs in the use process of the display panel; the problem of non-uniform brightness generated in the using process of the display panel is effectively solved, the replacement rate in the using process of the display panel is reduced, the cost generated when the display panel is replaced in the using process is reduced, the using cost of the display panel is reduced, the utilization rate of the display panel is increased, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a compensation method and compensation device for a display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display panels have become the mainstream direction of display panels due to their advantages of thinness, wide viewing angle range and flexible display. [0003] The lifespan of the light-emitting materials in the OLED display panel is different, so that the lifespan of the OLED display panel is shortened faster than that of the Liquid Crystal Display (LCD), so that after the user uses the OLED display panel for a period of time, the OLED display panel Remaining and aging phenomena of the display screen lead to the problem of poor brightness uniformity of the OLED display panel, which reduces the display effect of the OLED display panel, thereby reducing the experience of the user on the OLED display panel. In order to ...

[0003] The lifespan of the light-emitting materials in the OLED display panel is different, so that the lifespan of the OLED display panel is shortened faster than that of the Liquid Crystal Display (LCD), so that after the user uses the OLED display panel for a period of time, the OLED display panel The phenomenon of display screen residue and aging leads to the problem of poor brightness uniformity of the OLED display panel, which reduces the display effect of the OLED display panel, thereby reducing the user experience of the OLED display panel

In order to ensure the display effect of the OLED display panel, users generally adopt the method of replacing the OLED display panel, which will not only reduce the utilization rate of the OLED display panel, but also generate high costs, further reducing the user experience.
