Problems solved by technology

However, the flat layer 15 and the barrier layer 17 cannot effectively isolate the outside air and moisture.
When the flat layer 15 and the barrier layer 17 are in direct contact with the outside world, they will provide a path L for outside moisture and air to invade the inside of the organic electroluminescent device 200, thereby affecting the service life of the organic electroluminescent device 200.

Embodiment Construction

[0018] First, see image 3 and Figure 4 Shown are a top view and a schematic cross-sectional view of a preferred embodiment of the packaging structure of the organic electroluminescence device of the present invention, respectively. As shown in the figure, the organic electroluminescence (OLED) device 400 of the present invention is mainly provided with at least one organic electroluminescence component 41 above a color filter 30, and through the use of an encapsulant 45, the A package cover 43 is disposed on a part of the upper surface of the color filter 30 , and the package cover 43 includes a top plate 433 and a sealing area 431 such as a side plate is formed on a peripheral position of the package cover 43 . The color filter 30 is mainly provided with at least one color filter layer 33 on a part of the upper surface of a substrate 31, and a flat layer 35 (Overcoat) is covered above the color filter layer 33 to achieve flattening of the color filter layer. The purpose o...

Abstract

The invention relates to a packaging structure of organic electric exciting lighting device. The invention uses sealing pastern to arrange the sealing section at the outer part of sealing cover plate on the surface of basic plate of color filter and uses the sealing plate to cover at least one organic electric exciting lighting element. Since the invention can avoid the flat layer between the sealing section and the basic plate, the flat layer of color filter can avoid contact the outer condition and effectively reduce the possible path of outer water or air entering the inner space of organic electric exciting lighting device, to improve the service life of organic electric exciting lighting device.

Description

technical field [0001] The invention relates to a packaging structure, in particular to a packaging structure of an organic electroluminescence device. Background technique [0002] Compared with other light-emitting structures, organic electroluminescent devices have advantages such as self-luminescence, high brightness, wide viewing angle, low power consumption, high response speed, light and thin panel, simple component structure and manufacturing process, etc., so they are particularly favored by research institutes and manufacturers in various countries. Attention. [0003] Existing organic electroluminescent (OLED) devices 200, such as figure 1 and figure 2 As shown, at least one organic electroluminescent component 21 is mainly disposed on a part of the surface of a color filter 10 to achieve the purpose of light color filtering and full-color display. An encapsulation cover 23 is arranged on the upper surface of the color filter 10. The encapsulation cover 23 inc...
