Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0015] The present invention is achieved in this way, a method for processing a fully laminated liquid crystal display. For the TFTLCM in the full lamination module, OCA optical glue 2 is first attached to the surface of the upper polarizer, pre-baked, and after degassing under pressure, the CTP1 and TFTLCM3 are pre-laminated in alignment with a jig, and then Laminating machine is used for lamination operation, and after degassing by heating and pressure in degassing furnace, it becomes a finished product.

[0016] Specifically, TFT LCM3 first sticks OCA2 glue on the surface of the upper polarizer.

[0017] Specifically, after the TFT LCM3 is bonded to the OCA2, the defoaming operation is performed under high temperature and high pressure.

[0018] Specifically, after the TF...

Abstract

The invention belongs to the technical field of processing of full-lamination liquid crystal displays and provides a processing method of a full-lamination liquid crystal display. The method comprises the following implementation processes: laminating an OCA (Optical Clear Adhesive) on the surface of an upper polarizer of a TFTLCM (Thin Film Transistor Liquid Crystal Module) in a full-lamination module; pre-baking the OCA; after being pressurized de-foaming, performing counterpoint pre-laminating on a CTP (Computer-To-Plate) and the TFTLCM by using a fixture, and performing lamination operation by using a laminating machine; performing heated and pressurized de-foaming through a de-foaming furnace to obtain a finished product. A full-lamination product which is processed in the mode is mainly applied to the situation of inconvenience in integrated provision of a supplier caused by separate purchasing of CTP touch screens and modules. The processing method has the advantages that the display is easy to process; incoming materials are convenient to check; according to the processing method, after the OCA is laminated on the upper polarizer, the CTP is laminated after de-foaming is carried out at one time,; steam bubbles are less, and the lamination yield is high.

Description

technical field [0001] The invention belongs to the technical field of fully laminating module processing and provides a processing method for fully laminating liquid crystal displays. Background technique [0002] With the improvement of living standards, one of the development trends of color display modules is to develop towards the direction of full-fit TFT liquid crystal display modules. In the case that some CTP touch screens and modules are purchased separately and it is inconvenient for suppliers to integrate and provide them, the processing method of the full lamination module is generally to paste the polarizer on the TFT module with OCA, then directly bond it to the CTP, and finally pressurize it. After degassing, it is made into a finished product. Due to the presence of water vapor and insufficient softness in OCA thawing, the finished product after final lamination has low yield and many bubbles. Contents of the invention [0003] The purpose of the present...
