as shown in fig. 3, the surface of the flat layer 6 of the OLED display substrate is first formed to be uneven, so that the surface of the non-display area is uneven, and the uneven surface can effectively reduce the flow rate of the rheological organic material.
As shown in fig. 4, the first inorganic film 10 is formed on the OLED display substrate shown in fig. 3, since the planarization layer 6 is uneven, and the surface of the portion of the first inorganic film 10 located in the non-display area is also uneven, in this embodiment, two first barriers 41 and two second barriers 42 are formed at the edge of the OLED display substrate, and the first barriers 41 and the second barriers 42 jointly form a barrier structure, the distance between the first barriers 41 and the display area is smaller than the distance between the second barriers 42 and the display area, and the horizontal height of the first barriers 41 is smaller than the horizontal height of the second barriers 42, so that the first barriers 41 and the second barriers 42 can form a step structure, and the rheological organic material can be better blocked from crossing the barrier structure 4.
As shown in fig. 5 and 6, after the rheological organic material is inkjet printed in the filling area surrounded by the blocking structure 4, an organic material droplet 7 is formed, when the organic material droplet 7 is flowing flatly, the display area of the OLED display substrate can be shielded by using a mask plate 8, and the rheological organic material in the non-display area is cured by ultraviolet irradiation in advance, so that the organic material flowing into the non-display area is cured in advance, which is beneficial to the rheological organic material being solidified to form an organic thin film before crossing the blocking structure, so that the design distance between the edge of the display area and the blocking structure 4 can be reduced, the width of the non-display area is designed to be narrower, and the narrow frame of the display device is beneficial to being realized. Considering the accuracy and the alignment accuracy of the mask plate 8, when ultraviolet irradiation curing is performed on the rheological organic material in the non-display area in advance, the distance between the edge of the orthographic projection of the transparent pattern of the mask plate 8 on the OLED display substrate and the edge of the display area is greater than a first preset value, so that the influence of ultraviolet irradiation on the display area on the performance of the OLED display substrate can be avoided, and specifically, the first preset value can be 50-100 um. And the surface of the non-display area is uneven, the structure is favorable for reducing the flow rate of the rheological organic material, so that the rheological organic material is solidified to form an organic film before crossing the barrier structure, the design distance between the edge of the display area and the barrier structure can be further reduced, the width of the non-display area can be designed to be narrower, and the narrow frame of the display device is favorably realized.
As shown in fig. 7, the mask plate 8 is removed, and ultraviolet irradiation is continued to the non-display area, so that the organic material is cured to form the organic film 3.
As shown in fig. 8, the second inorganic film 11 is formed, so that the encapsulation thin film layer of the OLED encapsulation structure manufactured in this embodiment is made of the first inorganic film 10, the organic film 3 and the second inorganic film 11 which are stacked, and the encapsulation effect of the encapsulation thin film layer can be ensured. As can be seen from fig. 8, in the OLED encapsulation structure manufactured in this embodiment, the distance D2 from the edge of the display area to the blocking structure is much smaller than that of the conventional D1, so that a narrow bezel of the display device can be realized.
The embodiment of the invention also provides a display device which comprises the OLED packaging structure. The display device may be: the display device comprises a television, a display, a digital photo frame, a mobile phone, a tablet personal computer and any other product or component with a display function, wherein the display device further comprises a flexible circuit board, a printed circuit board and a back plate.
