Embodiment Construction

[0026] In order to introduce the solutions of the embodiments of the present invention more clearly, the idea and principle of the present invention are first described:

[0027] Such as figure 2 As shown, the curved display panel includes an array substrate 21 and an opposite substrate 22 , and a frame sealant 23 located around the curved display panel. In the process of implementing the present invention, the inventors found that, for curved display panels, the frame sealant 23 around the curved display panel has a great influence on light leakage in the dark state. The following is an analysis from the perspective of the force of the substrate.

[0028] by figure 2 The upper left corner of the opposite substrate 22 in the figure is taken as an example for illustration. The long side of the frame sealing glue 23 is bent, and both the long side and the short side of the frame sealing glue 23 have effects on the opposite substrate 22, such as image 3 As shown, there are...

Abstract

The embodiment of the invention discloses a curved surface display panel and a display device. The curved surface display panel comprises an array substrate, an opposite substrate and a plurality of floating spacers positioned in a non-display region; a height of each floating spacer is smaller than a box thickness between the array substrate and the opposite substrate; at a position of at least one floating spacer at side edges adjacent to bent side edges of the array substrate and the opposite substrate, a frame sealing glue structure positioned between the array substrate and the opposite substrate is cushioned; the sum of a thickness of the frame sealing glue structure and a thickness of the floating spacer in contact with the frame sealing glue structure is equal to the box thickness. Therefore, a stress of the array substrate and the opposite substrate, which is generated due to resistance to acting forces of the floating spacers and the frame sealing glue structure, is increased, and part of a stress generated due to bending can be balanced out, so that a combined stress is reduced and deflection of an optical axis is reduced, thereby reducing dark-state light leakage and improving image display quantity of the curved surface display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved display panel and a display device. Background technique [0002] In a curved liquid crystal panel, when the glass substrate is in a curved state, the refractive index of the glass substrate will change due to stress, resulting in birefringence, and optical retardation will occur when light is transmitted in the glass substrate (array substrate and opposite substrate). , plus the optical retardation caused by Advanced SuperDimension Switch (Advanced SuperDimensionSwitch, ADS) mode liquid crystal, such as figure 1 As shown, the direction of the optical axis changes. If the optical axis is not in the same direction or perpendicular to the direction of the polarizer, the light leakage phenomenon in the dark state is very serious, resulting in a decrease in the display quality of the picture, causing a decrease in contrast and a decrease in display effect.
