Problems solved by technology

The smear phenomenon refers to the phenomenon that when there is a moving object in the image displayed on the display panel, the moving object may produce a smear phenomenon on the display panel, and the smear phenomenon will seriously affect the viewing experience of the user.
[0003] Existing smear measurement methods for display panels often rely on human eye observation, but this method is highly subjective and has a low accuracy rate, making it impossible for technicians to make comprehensive and targeted improvements to the display panel for smear phenomena

Abstract

The embodiment of the invention relates to the technical field of display, and discloses a smear detection method, which comprises the following steps of: acquiring a measurement image in a process of moving from a first display position to a second display position when a test object of a display panel to be detected respectively displays three colors; determining tristimulus values in a smear area in the measurement image corresponding to the three colors; according to the tristimulus values in the smear area corresponding to the three colors, a white color coordinate measurement value is determined, and the white color coordinate measurement value is regarded as the white color coordinate measurement of the corresponding white smear area in the process of moving from the first display position to the second display position when the test object displays white; and determining a smear color cast value of the display panel to be tested according to the white color coordinate measurement value and a pre-acquired white color coordinate true value of the test object. According to the smear detection method and device and the storage medium, the method for accurately and objectively measuring the color cast condition of the smear area of the display panel to be detected is provided.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a smear detection method, device, and storage medium. Background technique [0002] In the production process of the display panel, in order to ensure the performance and quality, it is necessary to detect and judge the smear phenomenon of the display panel. The smear phenomenon refers to the phenomenon that when there is a moving object in the image displayed on the display panel, the moving object may produce a smear phenomenon on the display panel, and the smear phenomenon will seriously affect the viewing experience of the user. [0003] Existing smear measurement methods for display panels often rely on human eye observation, but this method is highly subjective and has a low accuracy rate, making it impossible for technicians to make comprehensive and targeted improvements to the display panel for smear phenomena .
