Description
The present invention relates to a bending test apparatus for bidirectional folding flexible display, and more particularly, to a bending test apparatus for a flexible display and a bending test for applying a physical deformation to a specimen of a flexible display, A double-sided flexible display device capable of obtaining a high reliability measurement result by relieving the stress concentration of a specimen by bending the specimen in both directions while stably supporting the specimen, and simultaneously testing a plurality of specimens using a detachable specimen holder To a bending test apparatus.
Flexible displays are attracting much attention as a representative product of next generation displays that can achieve the same image quality even when folded or bent. Flexible displays are expected to be applied to cell phones, PDAs, MR3 players, etc. because of their lightweight and non-breakable characteristics.
Flexible displays can be fabricated by thin and lightweight TFT array layers and color filters that adjust the direction of liquid crystals on thin and light substrates, and they are tested for various characteristics of flexible displays.
Korean Patent Registration No. 10-0970204 discloses an apparatus for inspecting material properties by using a tester which clamps both sides of a specimen and applies mechanical deformation such as stretching and bending to the specimen repeatedly by operation of an actuator.
In the above-mentioned prior art, when the clamp is subjected to the bending operation repeatedly for several tens of times with both sides of the specimen firmly fixed, the stress is locally changed at the boundary between the fixed part and the bending part by the clamp, It is not suitable for life test because it may occur or break. When testing the bending stress of a specimen, it is necessary to give a test condition that the stress applied to the bent portion works uniformly, so that a high reliability test result can be obtained.
In order to solve the problem of this prior art document, Korean Patent No. 10-1489667 (published on Feb. 4, 2015), which is a patent application filed by the present applicant, discloses a method in which a specimen is flatly spread on a support plate, And a bending test is performed in which one of the support plates is rotated to bend the specimen. Since the specimen is placed on the plate, the stress variation is reduced compared to the existing technique. However, a series of bending tests are carried out by lifting the specimen on the plate surface of the support plate, folding it back and returning it to its original position. The stress concentration in a specific site still remained, which made the reliability of the measurement result lower.
In addition, since the conventional technique has a structure for testing individual specimens, it was impossible to simultaneously test the same kind of specimens. Therefore, the longer the test time, the longer the time required.

Also, the connecting member may include a plurality of brackets and gear boxes coupled to both sides of the first and second support plates, the plurality of brackets being coupled to the first and second support plates using a fastening member, And the gear box includes a driven gear directly connected to the rotary shaft of the electric motor and a driven gear coupled to the driven gear.
The main gear and the driven gear rotate in mutually opposite directions and the main gear and the driven gear rotate the first and second support plates in opposite directions through the plurality of brackets .
Further, the gear box is installed on both sides of the first and second support plates.
According to another aspect of the present invention, there is provided a bending test apparatus for bidirectional foldable flexible display, comprising: an electric motor capable of normal and reverse rotation; A rotary plate that is rotated by the electric motor; A fixed plate installed at a predetermined interval facing the rotary plate; A first support plate for attaching one side portion of the specimen and a second support plate spaced apart from the first support plate by a predetermined distance to attach the other side portion of the specimen to the specimen, And a connecting member for connecting the second supporting plate to the first supporting plate so that the second supporting plate rotates synchronously with the first supporting plate in accordance with the rotation.
