Abstract:
A display module (100) and an OLED thin film encapsulation structure (10), the OLED thin film encapsulation structure (10) comprising an array film layer (1), an OLED film layer (2), a first inorganic film layer (3), an organic film layer (4), and a second inorganic film layer (5) which are sequentially stacked. Concave isolation grooves (11) are provided on one side, in a periphery area of the organic film layer (4) and opposite the first inorganic film layer (3), of the array film layer (1), and are provided along the periphery of the organic film layer (4). After ejection, an ink needs to be planarized, and during the planarization process, if the ink overflows, it will flow into the isolation trenches (11) to prevent the ejected ink from overflowing when the organic film layer (4) is formed by means of an inkjet method.
