Detection clamp and method for bending capability of flexible screen

Abstract

The invention provides a detection clamp for the bending capability of a flexible screen. The detection clamp comprises a clamp unit, an umbrella handle part, hinging seats and hinging umbrella ribs, wherein the clamp unit is of a sector-shaped flexible sandwich structure with two fixed ends and forms a containing space; the clamp unit is combined to form an umbrella surface part; the top of the umbrella handle part is fixed at the center of the umbrella surface part and the bottom end of the umbrella handle part is fixed; the hinging seats sleeve the umbrella handle part and move along the axial direction of the umbrella handle part; the hinging umbrella ribs are arranged along the peripheral direction of the hinging seats and correspond to the clamp unit; one end of each hinging umbrella rib is hinged to the corresponding hinging seat and the other ends of the hinging umbrella ribs are hinged to the corresponding clamp unit; the hinging seats are moved to drive the hinging umbrella ribs to change the radian of the clamp unit. According to the detection clamp provided by the invention, lossless fixation is carried out on an object to be detected in batch and an extrusion and bending test is carried out to test the bendability of the object to be detected; the problems of a traditional manner of clamping a flexible screen substrate that irreversible damage is caused and the detection efficiency is low and the like are solved. The invention further provides a detection method for the bending capability of the flexible screen.

Description

technical field [0001] The invention relates to the detection field, in particular to a fixture and a method for detecting the bending ability of a flexible screen. Background technique [0002] A flexible display is a display device made of soft materials that can be deformed and bent. Flexible displays are widely used in portable electronic devices due to their extremely thin, light, low power consumption, and deformable features. Since the bending performance of the flexible screen of the flexible display directly affects the quality of the flexible display, it is necessary to evaluate the bending characteristics of the flexible screen. [0003] In the prior art, the testing of the bendability of a flexible display panel is limited by fixtures, and all tests are performed on a single flexible screen. For example, the application number is CN20130698708.4, the name is "flexible screen bending test method and system", and the application number is CN201320881195.6, the na...
