Problems solved by technology

[0005] The purpose of the present invention is to provide a method for testing and calculating the bending strength of flexible parts, which can solve defects such as breakage, cracks, and fractures that occur when the bending stress of ultra-thin glass exceeds its bending strength when the existing display product is bent. Leading to problems such as reduced reliability of OLED screens

Embodiment

[0030] Such as figure 1 As shown, this embodiment provides a method for testing and calculating the bending strength of the flexible member 1, which includes the following steps: S1, obtaining the minimum bending radius R of the flexible member 1 that is close to failure 0 ;S2, establish the bending radius as R 0 The simulation model of the flexible part 1; S3, analyze and calculate the simulation model, and obtain that the bending radius is R 0 The maximum stress of the flexible part 1 in the bending area at time, the maximum stress is the bending strength of the flexible part 1 . In this embodiment, the flexible member 1 is ultra-thin glass.

[0031] Through the testing and calculation method of the bending strength of the flexible member 1 of this embodiment, the bending strength of the ultra-thin glass is obtained. When the ultra-thin glass of this embodiment is applied to a flexible display product, the flexible display product can be bent according to the bending stren...

Abstract

The invention relates to a method for testing and calculating the bending strength of a flexible part. The method comprises the following steps: acquiring the minimum bending radius R0 of the flexible part close to damage; establishing a simulation model of the flexible part with the bending radius of R0; the simulation model is analyzed and calculated, the maximum stress of the flexible part in the bending area when the bending radius is R0 is obtained, and the maximum stress is the bending strength of the flexible part. When the flexible piece is ultra-thin glass and the ultra-thin glass is applied to the flexible display product, the flexible display product can be folded or curled according to the bending strength of the ultra-thin glass, so that the bending stress of the ultra-thin glass is prevented from exceeding the bending strength of the ultra-thin glass, and the defects of breakage, cracks, fracture and the like of the ultra-thin glass are further avoided; and finally, the reliability reduction of a flexible display product is avoided.

Description

technical field [0001] The present application specifically relates to a method for testing and calculating the bending strength of a flexible piece. Background technique [0002] Organic Light Emitting Diode (English full name: Organic Light Emitting Diode, referred to as OLED) is an organic thin film electroluminescent device. With the development of display technology, OLED has the advantages of easy to form flexible structure, wide viewing angle, low voltage demand, high power saving efficiency, fast response, light weight, thin thickness, simple structure, low cost, almost infinitely high contrast, low power consumption. The advantages of electricity and extremely high response speed have become the mainstream in future development. [0003] OLED screens can not only be used as rigid screens, but also can be made into flexible screens to meet the needs of different customers for different forms. At present, the flexible screen technology mainly adopts two methods: one...
