    摘要: The present disclosure relates to a moire quantitative evaluation method. The method includes obtaining an image of a first pattern layer; obtaining coordinates of each of the first image units; according to the coordinates of each of the first image units and a thickness and a refractive index of a dielectric layer, determining coordinates of projection image units each of which corresponds to a corresponding one of the first image units along an oblique view light path; determining a pixel value of each of the projection image units according to pixel values of second image units in each of the surrounding regions to obtain an oblique view image; superimposing the image of the first pattern layer and the oblique view image to obtain a first superimposed image; converting the first superimposed image into a moire image; and performing a moire quantitative evaluation according to the moire image.

    摘要: This disclosure pertains to the technical field of liquid crystal display, and in particular to a display panel and a display apparatus. This display panel comprises a first substrate and a second substrate provided by cell-assembling, wherein the first substrate and the second substrate are both flexible and bendable, and wherein both of the first substrate and the second substrate are provided with a repulsion layer therein, which enables the first substrate and the second substrate to repel each other. By the addition of the repulsion layer to the display panel, the effect of maintaining a uniform cell thickness of the flexible display panel is achieved and the display panel is allowed to have a better displaying effect.

    摘要: The present invention discloses a method and device for image detection. After an acquired dark state image of a display panel is divided into a plurality of areas according to a preset rule, RGB values of each area are determined and converted into XYZ values. The L* and C* values in the CIE-LCH standard are calculated and statistical analysis is performed to the L* and C* values of the areas in the dark state image to determine statistical parameters of the display image. A dark state uniformity coefficient of the dark state image is determined based on the determined statistical parameters, and the uniformity of the dark state image of the display panel is determined through the dark state uniformity coefficient. A standard for evaluating uniformity of a dark state image is established through the above process, which facilitates unified detection of uniformity of the dark state image of the display panel.

    摘要: A display panel, a display device, and a method for manufacturing a display panel are provided. The display panel includes first and second substrates, first and second alignment films and a liquid crystal layer extending along a first direction and a second direction and sequentially along a third direction perpendicular to the first direction and the second direction. The liquid crystal layer includes a column of liquid crystal molecules along the third direction, and includes a first liquid crystal molecule closest to the first alignment film and a second liquid crystal molecule closest to the second alignment film. The first liquid crystal molecule and the second liquid crystal molecule have different tilting tendencies with respect to the plane defined by the first direction and the second direction, and form a twist angle.
