This is a National Phase Application filed under 35 U.S.C. 371 as a national stage of PCT/CN2014/078072, filed May 22, 2014, and claims priority benefit from Chinese Application No. 201410036350.3, filed Jan. 24, 2014, the content of each of which is hereby incorporated by reference in its entirety.
The present invention relates to the field of fabrication technology of flexible display panel, in particular, relates to a flexible device carrier and a method for attaching a membrane on the flexible device.
As shown in
However, since the flexible device 03 has a thickness smaller than a depth of the positioning groove 011 in the body 01, while attaching the membrane on the flexible device 03, there may be a gap between the membrane 04 and the flexible device 03, resulting in that, after the membrane 04 and the flexible device 03 are attached together, there may be defects such as bubbles or the like between the membrane 04 and the flexible device 03, thus product yield of the flexible display panel is lowered.
An object of the present invention is to provide a flexible device carrier for a flexible display panel and a method for attaching a membrane on a flexible device, which can improve yield of attaching the membrane on the flexible device and can improve product yield of the flexible display panel.
In order to achieve the above object, the present invention provides the following technical solutions.
A flexible device carrier for a flexible display panel, comprising: a bottom plate; a position-limiting plate provided opposite to the bottom plate and detachably mounted on the bottom plate through a position-limiting mechanism, wherein a slotted hole is provided on the position-limiting plate to match with one side of the bottom plate facing the position-limiting plate, so as to form a positioning groove for the flexible device.
In the flexible device carrier, the bottom plate and the position-limiting plate are detachably mounted together, and after the bottom plate and the position-limiting plate are mounted together, the positioning groove for positioning the flexible device and the substrate base is formed by matching the slotted hole provided on the position-limiting plate with one side of the bottom plate facing the position-limiting plate. When a membrane is to be attached on the flexible device, the substrate base and the flexible device are separated from each other by a corresponding process, and the substrate base is removed. Then, the position-limiting plate is detached from the bottom plate so that the flexible device is directly placed on a surface of the bottom plate. Subsequently, the membrane is attached on one side of the flexible device away from the bottom plate of the flexible device carrier by for example a roller and the like. With the flexible device carrier, while attaching the membrane on the flexible device, the membrane can be tightly attached on the side of the flexible device away from the bottom plate of the flexible device carrier, thus reducing probability of defects such as occurrence of bubbles between the membrane and the flexible device.
Therefore, the flexible device carrier of the present invention can improve quality of attaching the membrane on the flexible device and further improve product yield of the flexible display panel.
Preferably, a vacuum suction hole is provided at a position on the bottom plate opposite to each the slotted hole.
Preferably, the vacuum suction hole is a circular hole, and the circular hole has a diameter equal to or smaller than 1 mm.
Preferably, the position-limiting mechanism comprises: a slot provided on the bottom plate and a plug provided on the position-limiting plate, the plug is plugged in and matches with the slot; and/or, a slot provided on the position-limiting plate and a plug provided on the bottom plate, the plug is plugged in and matches with the slot.
Preferably, four pairs of slots and plugs are provided, and the connection lines between center points of projections of the four pairs of slots and plugs on the side of the bottom plate facing the position-limiting plate constitute a quadrilateral.
Preferably, the position-limiting mechanism comprises: a fastener provided on the bottom plate and a hook provided on the position-limiting plate, the fastener is clamped in and matches with the hook; and/or, a hook provided on the bottom plate and a fastener provided on the position-limiting plate, the fastener is clamped in and matches with the hook.
Preferably, both of the bottom plate and the position-limiting plate are of a quadrilateral shape, and at least one pair of sides of the bottom plate and the position-limiting plate are provided with the fastener and/or the hook thereon.
Preferably, the position-limiting mechanism is of a mortise and tenon structure.
In another aspect, the present invention further provides a method for attaching a membrane on a flexible device supported by the flexible device carrier provided by any technical solution said above, comprising: separating and removing the substrate base attached on the side of the flexible device away from the bottom plate of the flexible device carrier; detaching the position-limiting plate from the bottom plate of the flexible device carrier; attaching the membrane on the side of the flexible device away from the bottom of the flexible device carrier.
With the method to attach the membrane on the flexible device, after detaching the position-limiting plate from the bottom plate of the flexible device carrier, the flexible device protrudes from the bottom plate, and the membrane can be directly attached on the side of the flexible device away from the bottom of the flexible device carrier, defects such as bubbles between the membrane and the flexible device due to the gap therebetween after attaching the membrane on the flexible device is reduced, and product yield of the flexible display panel is improved.
Preferably, the step of attaching the membrane on the side of the flexible device away from the flexible device carrier comprises: attaching the membrane on the side of the flexible device away from the flexible device carrier by a roller pressure process.
