Step 67: the second inorganic barrier layer M5 of preparation.
The second inorganic barrier layer M5 is prepared in OLED display panel after borehole.First inorganic barrier layer M3, You Jiju Close nitride layer M4 and the compound composition encapsulated layer of the second inorganic barrier layer M5.It is inorganic by the second of the preparation of the techniques such as ALD, PLD, CVD Barrier layer M5 covers all areas of OLED display panel, including area A2 is arranged in viewing area A1 and electronic component.
So far, OLED display panel shown in fig. 6 is obtained.
According to above-described embodiment:
The embodiment of the present invention provides a kind of OLED display panel comprising position is arranged in viewing area and corresponding electronic component Area is arranged in electronic component, and electronic component setting area includes transparent area and buffer area, and the buffer area surrounds the light transmission It area and is contacted with the viewing area;The OLED display panel is formed with micro-nano structure in the buffer area;The OLED is aobvious Show that panel includes light emitting functional layer and encapsulated layer;It is logical that the position that the light emitting functional layer corresponds to the transparent area offers light transmission Hole, the encapsulated layer encapsulate the light transmission through-hole;Light emitting functional layer is opened up light transmission through-hole in the position of transparent area by the present invention, is gone In addition to obstructing biggish light emitting functional layer to light, light penetration is improved, while slow between transparent area and viewing area Setting micro-nano structure in area is rushed, when being cut by laser or other techniques carry out borehole, micro-nano structure can prevent cathode Etc. common electrode layers generate crackle to viewing area extend, alleviate cathode existing for existing comprehensive screen technology and produced in borehole The technical issues of raw crackle is extended into viewing area, and micro-nano structure can delay borehole area side during borehole Water oxygen invasion, it is final to promote device lifetime.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention Decorations, therefore protection scope of the present invention subjects to the scope of the claims.
