Abstract

The folding test device of the present invention may include a support member, a first swing frame, a second swing frame, a first support plate, and a second support plate. The first swing frame is swingably connected to the support member through a first rotation shaft, and the second swing frame is swingably connected to the support member through a second rotation shaft; the first support plateis supported by the first swing frame, and the second support plate is supported by the second swing frame, wherein the first rotation shaft and the second rotation shaft may be different from each other.

Description

technical field [0001] The present invention relates to a folding test device. Background technique [0002] With the development of information technology, the importance of display devices as a connection medium between users and information becomes more and more obvious. In response to this, the use of display devices such as Liquid Crystal Display Devices (Liquid Crystal Display Devices), Organic Light Emitting Display Devices (Organic Light Emitting Display Devices), Plasma Display Devices, etc. is increasing. [0003] Recently, a foldable display device that can be folded or bent by using a flexible plastic substrate or the like has attracted attention, unlike the existing flat display device using a glass substrate or the like. [0004] The case of folding such that the display surfaces of the foldable display device face each other is called infolding, and the case of folding such that the rear surfaces of the display device face each other is called out folding. ...
