Problems solved by technology

[0002] The traditional flexible polarizing cover often uses a flexible transparent hardened film to replace the polarizing protective layer in the flexible polarizing layer. For example, a CPI hardened film is used to replace the TAC or COP film in the polarizing layer. Layer integration, but the BM (black matrix) area is set on the back of the hardened film, so the overall thickness of the flexible polarizing cover is still relatively large, and the roll-to-roll (Roll to Roll) process cannot be used, resulting in high manufacturing costs and low production capacity. too low for mass production

Embodiment Construction

[0027] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. In the drawings, the thickness of regions and layers are exaggerated for clarity. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0028] Such as figure 1 As shown, the flexible polarizing cover includes a polarizer 1 and a hard coating (Hard Coating) 2 , and the hard coating 2 includes a visible area (VA) 22 and a BM (black matrix) area 21 surrounding the visible area 22 . The black matrix region 21 is composed of grooves arranged on the hardening film 2 and ink 211 fille...

Abstract

A flexible polarizing cover plate is provided, comprising a laminated polarizer and a hardened film, the hardened film includes a visible area and a black matrix area surrounding the visible area; the black matrix area is formed by being arranged on the flexible film The plurality of grooves and the ink filled in the plurality of grooves are formed after solidification. A preparation method of the flexible polarizing cover, a display panel and a display device comprising the flexible polarizing cover are also provided. In the flexible polarizing cover of the present invention, the ink is directly embedded into the structure of the cover to form a BM area, and no additional BM area is required, thereby reducing the overall thickness of the cover. At the same time, the method of the present invention does not require ink patterning treatment on the back of the cover plate, so that the flexible polarizing cover plate of the present invention can adopt a Roll to Roll process, which improves production efficiency and reduces costs.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a flexible polarizing cover plate of a display device and a preparation method thereof, as well as a display panel and a display device comprising the flexible polarizing cover plate. Background technique [0002] The traditional flexible polarizing cover often uses a flexible transparent hardened film to replace the polarizing protective layer in the flexible polarizing layer. For example, a CPI hardened film is used to replace the TAC or COP film in the polarizing layer. Layer integration, but the BM (black matrix) area is set on the back of the hardened film, so the overall thickness of the flexible polarizing cover is still relatively large, and the roll-to-roll (Roll to Roll) process cannot be used, resulting in high manufacturing costs and low production capacity. low enough to be mass-produced. Contents of the invention [0003] In order to overcome the abo...
