Problems solved by technology

However, this method often causes uneven stress distribution on the display panel after the display panel is stressed due to the distribution of the lines or components on the tested display panel, which makes the flexural curvature of the tested display panel unpredictable at each position.
In other words, the experimental data obtained in this way tends to be more variable and less informative

Abstract

The invention discloses a flexible board deflection testing device and a testing method thereof. The flexible board deflection testing device includes a first barrel, a first clamping part, a swing arm guide unit and a second clamping part. A portion of the first barrel surface is formed as the barrel surface; the barrel surface has a first location thereon. The first clamping part is provided on one side of the first barrel for clamping the soft board under test. The swing-arm guide unit rotates with an axis parallel to the axial direction of the first cylinder as a rotation axis, and when rotating, can be raised or lowered relative to the first plane defined by the first clamping part and the first position. The swing-type guide unit is provided with a second clamping part for clamping the other end of the soft board under test, and the second clamping part can move toward or away from the first tube along the swing-arm guide unit.

Description

technical field [0001] The present invention relates to a flexible board deflection test device and a test method; specifically, the present invention relates to a display panel deflection test device and test method. Background technique [0002] With the evolution of technology, the technology of flat panel display is also constantly improving. In order to meet the needs of products, flat-panel displays continue to be researched toward increasing the display area, narrowing the frame, thinning the thickness of the module, and improving the display effect. However, in addition to the above-mentioned research directions, flat-panel displays have recently begun to develop towards the direction of flexible structures. [0003] Corresponding to the production of flexible display panels, it is also necessary to develop relevant product verification methods, so that the products can be tested in a quantitative manner such as the bending curvature and the number of times of bendi...
