Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The main solutions of the embodiments of the present invention are as follows: a resin layer and a sealing layer are formed on the light-transmitting substrate, and an extended film is formed on the sealing layer; and the light-transmitting substrate is peeled off from the resin layer.

[0037] The existing separation of the resin layer from the light-transmitting substrate is usually a laser lift off (Laser lift off, LLO) process to separate the display panel and the resin layer from the light-transmitting substrate. However, in the process of separating the resin layer from the light-transmitting substrate, the resin layer (polyimide) will cause the resin layer to curl and warp due to stress, which in turn will cause damage to the electronic components of the display panel. affect the function of electronic c...

Abstract

The invention discloses a display panel stripping method, and the method comprises the steps: forming a resin layer and a sealing layer on a light-transmitting substrate, and forming an extension filmon the sealing layer; and stripping the light-transmitting substrate from the resin layer. The technical problem that a display panel is curled and warped when being separated from the light-transmitting substrate can be solved, the flatness of the display panel is guaranteed, and the yield of the display panel is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for peeling off a display panel. Background technique [0002] The manufacturing method of the flexible display panel is usually based on a light-transmitting substrate as a carrier, coating a layer of polyimide film on the entire surface of the light-transmitting substrate, curing the resin layer, and the resin layer acts as a flexible substrate; The thin film transistor array layer, the anode layer, the organic light-emitting layer, the cathode layer and the sealing layer are fabricated sequentially from the top, so that the flexible display motherboard is produced; and then the cutting process is applied to divide the light-transmitting substrate and the flexible display motherboard into individual pieces. Finally, for each single flexible display panel, laser lift off (Laser lift off, LLO) process is applied to separate the resin layer from the light-transmitting su...
