Abstract

The embodiment of the present invention discloses a method, device, device and storage medium for determining the trailing time of a display device. The method includes: setting the background color of the currently displayed page and the foreground color of the first display area, wherein the first The pattern formed by the foreground color of the display area is switched between the display state and the disappearance state at a first set frequency; the first brightness value of the first display area is obtained, and the trailing time is determined according to the first brightness value, wherein, The measurement frequency of the first brightness value is the second set frequency. From the perspective of quantification, the tailing time is measured, with high consistency, reproducibility and good stability.

Description

technical field [0001] The present invention relates to the data processing technology in the display device, in particular to a method, device, device and storage medium for determining the smear time of the display device. Background technique [0002] When a display device displays moving images, smearing usually occurs. The smearing phenomenon of moving images generally refers to the phenomenon that moving images leave afterimages behind them on a relatively still background, making the boundaries blurred. The degree of afterimage is the most direct measure of the degree of smearing. It is directly proportional to the moving speed of the object, and its proportional coefficient is related to the characteristics of the display device itself, and has a time dimension. The proportional coefficient is called the smearing time. [0003] In the prior art, the determination of the smear time can be realized through the subjective judgment of the single product or the subjectiv...
