    Abstract: A flexible polarizer and a flexible touch display device. The flexible polarizer includes: a support protective layer; a linear polarized layer provided on the side of the support protection layer and comprising an acidic substance; a retardation layer provided on the side of the linear polarized layer distant from the support protection layer, and bonded to the linear polarized layer by means of a first bonding layer; and a block layer provided on the side of the retardation layer distant from the linear polarized layer. The block layer is bonded to a flexible touch display panel of the flexible touch display device by means of the second bonding layer. The block layer is used for blocking the acidic substance in the linear polarized layer from permeating into the flexible touch display panel.

    Abstract: The present disclosure relates to the field of display and, in particular, to a polarizing structure, a modular structure, and a manufacturing method thereof. The polarizing structure includes a support film having first and second bonding sides disposed oppositely in the thickness direction thereof, wherein the first bonding side can be bonded to the curved cover plate, and a polarizer bonded on the second bonding side of the support film. An outer contour of the orthographic projection of the support film on a reference plane is located outside the outer contour of the orthographic projection of the polarizer on the reference plane. The minimum distance between the outer contours of the orthographic projections of the support film and the polarizer on the reference plane may be, for example, greater than 0.5 mm. The reference plane is a plane perpendicular to the thickness direction.

    Abstract: A flexible touch display module (100) and a touch display device (1000) including the flexible touch display module, the flexible touch display module (100) includes: a flexible display panel (1), a flexible cover plate (2), a linear polarization layer (3), a first retardation plate (4) and a second retardation plate (5). An absorption axis of the linear polarization layer (3) is at an angle of about 90°. The first retardation plate (4) includes a first retardation film (41), and the first retardation film (41) is a liquid crystal layer having a quarter-wavelength retardation. The first retardation film (41) has a major axis and a minor axis in a plane parallel to flexible display panel (1), and an included angle between a direction in which the minor axis of the first retardation film (41) extends and the absorption axis of the linear polarization layer (3) is about 45°.

    Abstract: A cover for a display panel is provided. The cover for a display panel includes a cover film; a first adhesive layer on the cover film; a polarizer on a side of the first adhesive layer away from the cover film; a phase difference layer on a side of the polarizer away from the first adhesive layer; a second adhesive layer on a side of the phase difference layer away from the polarizer; and an ultra-thin glass and an opaque filler layer on a side of the second adhesive layer away from the phase difference layer. The opaque filler layer includes an opaque material. The opaque filler layer abuts at least a portion of a periphery of the ultra-thin glass.
