Abstract

The embodiment of the invention provides a Mura detection method and device of a display panel and a readable storage medium, a pixel circuit in the display panel comprises a data write-in module, the control end of the data write-in module is connected with a first scanning signal end, and the first end of the data write-in module is connected with a data voltage signal end; the control end of the first light-emitting control module is connected with the light-emitting control signal end, and the first end of the first light-emitting control module is connected with the second end of the data writing module; the control end of the negative voltage input module is connected with a second scanning signal end, the first end of the negative voltage input module is connected with a negative voltage signal end, and the second end of the negative voltage input module is connected with the second end of the first light-emitting control module; the method comprises the steps that for any ith pixel circuit, a data writing module, a first light emitting control module and a negative voltage input module are controlled to be switched on, and current parameters of the ith pixel circuit are obtained; and determining a Mura detection result of the display panel according to the current parameters of the plurality of pixel circuits of the display panel. According to the embodiment of the invention, the accuracy of Mura phenomenon detection can be improved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a Mura detection method, device and readable storage medium of a display panel. Background technique [0002] With the development of the display technology, the application of the display panel is more and more extensive, and the requirement for the display effect of the display panel is also higher and higher. During the production process of the display panel, due to the production process and other reasons, the display panel may generate a mura phenomenon. The Mura phenomenon refers to the phenomenon that the brightness displayed on the display panel is uneven, causing various traces. The Mura phenomenon will reduce the display effect of the display panel. [0003] The inventors of the present application have found that the detection accuracy of the mura phenomenon in the display panel in the related art is low, and it is difficult to accurately dete...
