- OLED Organic Light-Emitting Diode
- the current OLED display panel is generally packaged by means of a plastic package.
- the process of encapsulation by means of a glue encapsulation is as follows: a film 104 is formed on the OLED substrate 101 (ie, the substrate on which the OLED structure is formed), and the OLED substrate 101 is disposed opposite to the package cover 103 to complete the package. Since moisture in the air may penetrate the film 104, the lifetime of the organic luminescent material in the OLED structure 102 is negatively affected, so that the lifetime of the organic luminescent material in the OLED structure 102 is prevented from being avoided as much as possible by the moisture in the air.
- a moisture barrier layer 105 completely covering the OLED structure is also disposed between the OLED substrate 101 and the adhesive film 104. Since the moisture barrier layer 105 has a certain thickness and width, the moisture barrier layer 105 increases the volume of the OLED display panel.
- the current OLED display panel in order to prevent the water vapor in the air from having a negative influence on the organic luminescent material in the OLED structure, the current OLED display panel generally includes a moisture barrier layer having a certain thickness and width, thereby increasing the volume of the OLED display panel.
