Problems solved by technology

The flexible cover located on the outermost layer of the flexible display panel will be subject to greater stress when it is bent inward or outward, so it is also the most prone to cracks in the bending area.
[0003] The current flexible cover is generally composed of a flexible substrate and a hard coating. The hard coating takes into account the surface hardness (stiffness) and other characteristics, resulting in poor foldability. Therefore, the stress generated by the flexible display panel during folding is easy. Cracks occur when the ultimate stress of the hard coating is exceeded
Moreover, it is inevitable that the flexible cover will cause fine cracks at the edge of the bending area during the process of processing, transportation, and use, and the stress of such fine cracks will gradually accumulate and spread during the bending process of the flexible cover, and even lead to hard cracks. The coating may diffuse and fracture along the micro-cracks within the stress limit, thereby reducing the service life of the flexible cover

Abstract

The invention discloses a flexible cover plate which comprises a hard coating, a flexible base material layer and a protective layer, the hard coating is arranged on the first surface of the flexible base material layer in a stacked mode, and the protective layer is arranged on the peripheral side of the hard coating and the peripheral side of the flexible base material layer. The flexible cover plate is divided into at least one bending area and at least two non-bending areas, the bending area is arranged between the non-bending areas, the modulus of the flexible base material layer corresponding to the bending area is smaller than that of the flexible base material layer corresponding to the non-bending areas, and the modulus of the hard coating layer corresponding to the bending area is smaller than that of the hard coating layer corresponding to the non-bending areas. The invention further discloses a flexible display panel comprising the flexible cover plate.

Description

technical field [0001] The invention relates to the field of flexible displays, in particular to a flexible cover and a flexible display panel with the flexible cover. Background technique [0002] With the progress of science and technology and the continuous development of display technology, the flexible display panel can change the display form of the display device and improve the display effect of the display device. During the folding process of the flexible display panel, the bending area is deformed to generate stress, wherein, the outermost layer of the flexible display panel receives the largest tensile stress, and the innermost layer of the flexible display panel receives the largest compressive stress. The flexible cover located at the outermost layer of the flexible display panel will be subject to greater stress when bent inwards or outwards, and thus cracks are most likely to occur in the bending area. [0003] The current flexible cover is generally compose...
