Abstract

The invention discloses a flicker judgment method and a flicker judgment device, and the method comprises the steps: obtaining a time domain brightness signal of a to-be-detected panel when a brightness parameter is a preset brightness value, wherein the display brightness of the to-be-detected panel changes with time; obtaining the flicker degree of the to-be-detected panel according to the time domain brightness signal; determining a flicker degree threshold value of the to-be-detected panel under the preset brightness value according to a calculation strategy corresponding to the brightness range where the preset brightness value is located; and based on the flicker degree of the to-be-detected panel and the flicker degree threshold value, determining whether the to-be-detected panel flickers or not under the preset brightness value. According to the flicker judgment method provided by the invention, the process of judging whether the to-be-detected panel flickers or not can be simplified.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular to a flicker judging method and a flicker judging device. Background technique [0002] With the application of LTPO (Low Temperature Polycrystalline Oxide, Low Temperature Polycrystalline Oxide), the source leakage rate of display panels such as OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has been significantly improved, and the refresh rate can be further reduced, so that Use a lower refresh rate to save power consumption and improve image quality. [0003] Although the display panel with a low refresh rate has many advantages, it also has a prominent problem, which is periodic flickering. Therefore, in the manufacturing process of the display panel, it is necessary to judge whether it is flickering in order to debug the display panel. [0004] The inventors of the present application found that currently in the manufacturing process, th...
