A method for handling a product substrate includes bonding a carrier to the product substrate by: applying a layer of a temporary adhesive having a first coefficient of thermal expansion onto a surface of the carrier; and bonding the carrier to the product substrate using the applied temporary adhesive. A surface of the temporary adhesive is in direct contact to a surface of the product substrate. The temporary adhesive includes or is adjacent a filler material having a second coefficient of thermal expansion which is smaller than the first coefficient of thermal expansion, so that stress occurs inside the temporary adhesive layer or at an interface to the product substrate or the carrier during cooling down of the temporary adhesive layer.

According to a flexible OLED device production method of the present disclosure, after an intermediate region (30i) and a flexible substrate region (30d) of a plastic film (30) of a muitilayer stack (100) are divided, the interface between the flexible substrate region (30d) and a glass base (10) is irradiated with laser light. The multilayer stack (100) is separated into the first portion (110) and the second portion (120) while the multilayer stack (100) is kept in contact with the stage (210). The first portion (110) includes a plurality of OLED devices (1000) which are in contact with the stage (210). The OLED devices (1000) include a plurality of functional layer regions (20) and the flexible substrate region (30d). The second portion (120) includes the glass base (10) and the intermediate region (30i). The step of irradiating with the laser light includes forming the laser light from a plurality of arranged laser light sources and temporally and spatially modulating a power of the plurality of laser light sources according to a shape of the flexible substrate region of the synthetic resin film such that the irradiation intensity of the laser light for at least part of the interface between the intermediate region (30i) and the glass base (10) is lower than the irradiation intensity of the laser light for the interface between the flexible substrate region (30d) and the glass base (10).

An apparatus of separating a flexible panel from a glass substrate is provided. The apparatus of separating a flexible panel from a glass substrate includes a console, a movable object fixing table, a position catcher, a lifting platform, and a suction separator. The console respectively drives the movable object fixing table and the lifting platform to move to a first position and a second position according to a real-time position of a fixed object fixed on the movable object fixing table captured by the position catcher, and a adhesive element of the suction separator tightly attaches to the flexible panel of the fixed object fixed on the movable object fixing table, drives the lifting platform to move to a direction away from the movable object fixing table, and drives the movable object fixing table to move to a direction away from the suction separator to separate the flexible panel from the glass substrate of the fixed object and fix the flexible panel on the adhesive element.

A movable member is gripped in a delamination-start configuration, and the other-end side of a rib of a delamination member is pressed towards the other-end side of a flexible plate. The flexible plate then warps and deforms about the other end side of the flexible plate, which is supported by a support member, the flexible plate deforming along the direction in which delamination progresses. In concert with the delamination action, a reinforcing plate also warps and deforms along with the flexible plate, the reinforcing plate being vacuum-chucked to an air-permeable electroconductive sheet on the flexible plate, and the reinforcing plate is sequentially delaminated from a substrate 2 along the direction in which delamination progresses.
