Abstract

The invention discloses an OLED display device and a packaging method thereof. The OLED display device is composed of a first substrate, a second substrate, a first packaging structure and a second packaging structure. The first packaging structure is arranged between the first substrate and the second substrate; and thus at least one organic luminescence display element is sealed into the space encircled by the first substrate, the second substrate and the first packaging structure. The second packaging structure is arranged in a predetermined area between the first substrate, the second substrate and the first packaging structure. According to the invention, a spraying range and a spraying value of a packaging material can be controlled precisely; the sealing performance and the mechanical strength of the OLED display device can be guaranteed; and the packaging material amount and the production cost can be reduced.

Description

technical field [0001] The invention relates to a display device and a packaging method, in particular to an OLED display device and an OLED packaging method. Background technique [0002] An OLED display device is a current-mode semiconductor light-emitting device based on organic materials. Its typical structure is to make a layer of tens of nanometers thick organic light-emitting material on the ITO glass as the light-emitting layer, and there is a layer of low-power metal electrodes above the light-emitting layer. When a voltage is applied to the electrodes, the light-emitting layer produces light radiation. The light-emitting mechanism and process of OLED is to inject electrons and holes from the cathode and anode respectively. The injected electrons and holes are transported in the organic layer and recombined in the light-emitting layer, thereby exciting the molecules of the light-emitting layer to generate singlet excitons. The singlet excitons radiatively decay to...
