The invention provides a novel film packaging method so as to solve a problem that the atomic layer deposition (ALD) film is compact but the rate is slow in the device film packaging field. The method comprises: step one, depositing a first inorganic barrier layer on a substrate by an atomic layer deposition method; step two, depositing a second inorganic barrier layer on the inorganic barrier layer prepared in the step one by means of physical vapor deposition; step three, depositing a third inorganic barrier layer on the inorganic barrier layer deposited in the step two by using the atomic layer deposition method; step four, preparing an organic barrier layer to form a periodic structural barrier layer; and step five, repeating the steps from the step two to step four to form a film packaging structure having a plurality of cycles. Because of combination of the ALD with other common film deposition methods, the novel film packaging method has advantages of high film compactness and fast film forming rate.

Film packaging method

The invention provides an encapsulation method of an OLED display panel. A circle of elastic blocking layer surrounding a display area is formed outside the display area; a mask plate used for depositing an encapsulation layer is a rigid mask plate; when the encapsulation layer is deposited, the rigid mask plate is supported by the elastic blocking layer; and seamless joint between the upper surface of the elastic blocking layer and the rigid mask plate is achieved through elastic deformation of the elastic blocking layer, so that the deposited encapsulation layer is completely located at the inner side of the elastic blocking layer; extended deposition of the encapsulation layer is effectively avoided; the encapsulation layer is prevented from covering an IC to affect IC binding; and development of a narrow-border panel is facilitated.
