Embodiment Construction

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] Such as Figure 1-Figure 3 As shown, a bending test device includes a first clamp 10, a second clamp 20 and a stroke limiter 30, the first clamp 10 is used to clamp the first edge of the flexible component, and the second clamp 20 is used to clamp the flexible component The second side of the second side, the first side is set opposite to the second side; the stroke limiter 30 is used to limit the travel of the second clamp 20 to move to both sides of the clamping plane 11 of the first clamp 10, so that the two ends of the second clamp 20 The first fixture 10 can move in an arc to both sides of the clamping plane 11 at different speeds, so as to drive the flexible component to bend to both sides.

[0031] The bending test device of the embodiment of the present appli...

Abstract

The invention relates to the technical field of semiconductor device testing equipment, in particular to a bending testing device which is used for testing a flexible component and comprises a first clamp, a second clamp and a stroke limiting piece, the first clamp is used for clamping a first edge of the flexible component, the second clamp is used for clamping a second edge of the flexible component, and the second edge and the first edge are oppositely arranged; the stroke limiting piece is used for limiting the stroke of the second clamp moving towards the two sides of the clamping plane of the first clamp, so that the two ends of the second clamp can move towards the two sides of the clamping plane of the first clamp in an arc mode at different speeds, and the flexible component can be driven to bend towards the two sides. The bending test device provided by the embodiment of the invention can drive the flexible component to bend towards the two sides, so that inward bending and outward bending tests of the flexible component are realized.

Description

technical field [0001] The present application relates to the technical field of semiconductor device testing equipment, in particular to a bending testing device. Background technique [0002] With the rapid development of display technology in recent years, flexible displays have attracted great attention, including full-screen, bendable, and even foldable mobile phones with fixed curve shapes will be widely used in the future market. As users have higher requirements for display performance, foldable flexible displays have gradually become a hot spot in industry research. [0003] The bending test fixture is an important tool for testing parameters such as bending angle and bending times of flexible displays, and is of great significance for measuring the performance of bending displays. However, the bending test of the existing bending test fixture has certain limitations, and cannot meet the testing requirements of various forms of bending tests on flexible components ...
