  • Patent number: 10164213
    Abstract: The present disclosure provides a method for bonding an integrated circuit (IC) chip onto a flexible display body. The method includes providing a substrate having a flexible display body thereon, and aligning a first stiffening component with the flexible display body having an IC bonding region. The method further includes attaching the first stiffening component onto a front surface of the flexible display body, and separating the substrate from the first stiffening component and the flexible display body to expose a back surface of the flexible display body; and bonding an IC chip onto the IC bonding region.

  • Publication number: 20170271625
    Abstract: The present disclosure provides a method for fabricating a display substrate for a display panel. The method includes providing a flexible organic light-emitting diode (flexible OLED) substrate with a thin-film transistor (TFT) layer on the flexible OLED substrate and a patterned adhesive layer on the TFT layer, wherein the TFT layer includes at least one testing area; providing a barrier film (BF) with a patterned laser barrier layer on a surface of the BF, the surface of the BF facing the TFT layer; and bonding the BF onto the flexible OLED substrate such that at least a portion of the patterned laser barrier corresponds to the at least one testing area. The method also includes irradiating a laser beam along a cutting line on the BF to remove a first portion of the BF.
