Example Embodiment

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0019] Such as figure 1 As shown, the present invention is realized in this way, a production and processing method of a fully bonded TFT liquid crystal display module. The TFT LCM in the fully bonded module does not assemble the backlight first, and the FOG in the TFT LCM is first on the surface of the upper polarizer. Laminate OCA optical adhesive, after pre-baking and pressure deaeration, use a fixture to perform alignment pre-laminating processing of CTP and FOG, and use laminating machine for pressing and heating by deaeration furnace After pressure defoaming, use the fixture to assemble the backlight.

[0020] Specifically, the TFT LCM part does not assemble the backlight first, and the FOG 3 is first attached with OCA2 glue.

[0021] Specifically, after the TFT LCM FOG 3 is la...

Abstract

The invention provides a manufacturing and processing method for a direct-bonding TFT LCM (Liquid Crystal Module), and belongs to the technical field of direct-bonding module processing. The realization process of the manufacturing and processing method is as follows: not assembling backlight on TFT LCM in a direct-bonding module, and gluing OCA on the surface of an up polarizer of FOG in the TFT LCM; after pre-baking and pressurizing for defoaming, using a jig to carry out aligned pre-gluing processing on CTP and FOG; adopting a gluing machine for pressing operation; reusing the jig to assemble backlight after warming and pressurizing for defoaming through a defoaming furnace. The manufacturing and processing method has the advantages that direct-bonding products processed by adopting the method has the advantages of being simple in processing process, high in alignment precision, less in foams in product gluing, high in yield and the like.

Description

technical field [0001] The invention belongs to the processing technology of fully laminating modules, and in particular relates to a production and processing method of fully laminating TFT liquid crystal display modules. 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. For ordinary suppliers, because CTP and TFT LCD modules are not produced by the same supplier, generally FOG is first assembled with backlight to form a TFT LCD module, and then assembled with CTP after bonding OCA glue. This production and processing method has an assembly tolerance between TFT FOG and backlight, and a full lamination tolerance between TFT LCD module and CTP, and it is easy to form a full lamination gap, resulting in poor defoaming, which eventually leads to the assembly of TFT FOG and CTP products. If there is a large deviation b...
