Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Referring to shown in Fig. 3, is the explosive view of a kind of AMOLED modular structure of the present invention.The object of the invention is to solve the problem that thickens in AMOLED module packaging process, because of in full laminating process, OCA optical cement need be filled and led up the enclosed space forming on cover-plate glass, makes to need the OCA optics glue-line thickening of use, and then has increased the thickness of AMOLED module.Below in conjunction with accompanying drawing, a kind of AMOLED modular structure of the present invention is described.
As shown in Figure 3 and Figure 4, a kind of AMOLED modular structure of the present invention comprises a cover-plate glass 10, ink layer 20, OCR gelatine layer 50, OCA optics glue-line 30 and display module 40.
Ink layer 20 is arranged at the end at cover-plate glass 10 back sides, it is the edge at cover-plate glass 10 back sides, be formed with an enclosed space with cover-plate glass 10, OCR gelatine layer 50 is placed in the enclosed space forming between ink layer 20 and cover-plate glass 10, and fill and lead up this enclosed space, make the back side of cover-plate glass 10 smooth.This OCR glue is filled and led up process and cover-plate glass 10 and ink layer 20 and is completed in same technique, the manufacturer that can be chosen in making cover-plate glass has located the operation of filling and leading up of OCR glue, because OCR glue need solidify with UV, and UV can have damaging influence to the display module 40 of AMOLED, so above-mentioned OCR glue solidification process need complete in advance, avoids the impact of UV on display module 40.Then, with OCA optical cement, display module 40 being bonded on OCR gelatine layer 50 and ink layer 20 is the back side of cover-plate glass 10, has formed OCA optics glue-line 30 and has been placed in the structure between display module 40 and OCR gelatine layer 50.
Because adopting OCR gelatine layer 50 to fill and lead up the enclosed space forming between ink layer 20 and cover-plate glass 10, can be so that cover-plate glass 10 and display module 40 while entirely fitting, be used ultra-thin OCA optical cement.Because the back side of cover-plate glass 10 is smooth, when bonding with OCA optical cement, can not produce air bubble problem, so that OCA optical cement can be accomplished is the thinnest.In contrast, in the prior art, if adopting OCA optical cement directly fits entirely, during the enclosed space at its filling cap glass sheet 10 back sides, can produce bubble because of this offset, this bubble can affect the caking ability of AMOLED modular structure, think the bubble get rid of producing, need to apply thicker OCA optical cement.When the thickness of ink layer 20 is 0.03 millimeter, at least need the OCA optical cement of 0.3 millimeters thick.
